Dude sweet.. KA supercharger kit!!

[s13satch]

I may have missed it on one of the previous post, but is there a website to order this kit from?

I may have missed it on one of the previous post, but is there a website to order this kit from?

the new website for the supercharger systems will be up soon. it will have pricing, pics, descriptions, dyno videos and a forum moderated by mr. knight and myself. we will be releasing eaton based kits for twin cam ka's and intercooled centrifugal supercharger kits for both e and de's. we are also currently in the process of creating ka block to vg30dett trans adapters, z32 eaton kits, altima kits (eaton and centr.), new intake and turbo manifolds and twincharged ka packages.

the new site will be done soon, in the meanwhile deposits on eaton-based kits will be taken at the boosthead site.

GREG, I CAN STILL DUPLICATE THOSE KITS. I REMEMBER EVERY DETAIL. JUST NEED A FEW INTERESTED PARTIES TO JUSTIFY MAKING THE KITS AND BUYING A SPARE ENGINE FOR THE PATTERN AND FITMENT. HAVENT SPOKEN TO DOC IN A WHILE. TURBO'D HIS 'BUSA AS WELL!!! 335 WHEEL HP ON A BIKE--TOO WILD FOR ME.

[Burnsey]

i like the idea of SC kits ... would it produce better or worse gas mileage than a turbo?

Cant wait to see the finished products .Sadly I will not be able to keep in touch during the next couple of months because I am leaving for Marine Corps basic, but if you feel the need you may keep in contact with a close friend of mine using the same Email. I am having him look over things while I am gone.

Oh Greg thanks for the tagging cards, came in this morning .

Cant wait to see one of these kits for myself (on one of my cars ), and on cars of fellow NICOnauts .

Hi Tom -

From what I recall, Wes was heading up the plans to get a kit replicated... When I go back down to Orlando, I intend to get the original brackets and pullies and manifold off the original boosted Q.

I will have a spare VH45DE here soon, but I'm a long way from you and shipping would be counterproductive.

We'll discuss further I'm sure...

[CCurate]

Please oh Please huryy and finish these kits. For more than two years I have been looking for something to compliment the torque of the KA. I didn't want to turbo charge but that was my only choice until now. I don't care for high horsepower numbers. They mean squat to me. Now torque (Homer simpson style; mmmmmmmmmmmmmmmmmmmmmmm Torque) thats what I want. Yeah throttle response. I mean this is great I can't wai- oh oh oh oh............. gimme a sec i have to change my pants. like I was sayin PLEASE hurry I want more. gimme me more. thanx in advance

[hybrid_flyer]

please forgive my ignorance but what are the differences between the centrifugal and easton based sc's?? what are the pros and cons of both?

Also I read in an earlier post that you were planning on adding additional injectors to handle the extra fuel. But you were also wanting to make the sc's alcohol injected. Where do u plan on puttin all the new injectors?? just curious about this because I love the idea of sc's but dont want to have to install an intercooler as well

thanks for your time.

glad to see somebody finally getting around to this I have been waiting for this for a long time

[JesusLikesKFC]

difrence is in design. centrifugal is more like a compressor side of the turbocharger made belt driven, has more lag and better top end posibilitys. eeton usses a twin screw design style compressor.

FIRST OF ALL, I WANT TO THANK YOU FOR YOUR SERVICE TO THIS GREAT COUNTRY. TKTURBO GIVES SPECIAL DISCOUNTS TO MILITARY PERSONNEL. WHEN YOU RETURN, FEEL FREE TO CONTACT ME PERSONALLY AND I WILL SET YOU UP WITH A KIT AT A HUGE DISCOUNT. WHILE SOME DONT UNDERSTAND WHAT DRIVES BRAVE YOUNG PEOPLE TO ENLIST, WE FEEL IT IS A SPECIAL BREED WHO DOES AND THEY DESERVE SPECIAL TREATMENT. THE ENTIRE WORLD OWES A DEBT OF GRATITUDE TOWARDS OUR GREAT MILITARY.

THESE KITS ARE AVAILABLE RIGHT NOW. WE ALWAYS TEST SYSTEMS ON THE DYNO TO EXTRACT EVERY POSSIBLE HP, AND THE DIFFERENCE BETWEEN WHAT YOU WOULD BUY NOW AND WHAT WE WILL EVENTUALLY HAVE ON OUR DYNO WILL BE A ONLY FEW HP DIFFERENCE. AS I SAID IN PREVIOUS POSTS, EXPECT AT LEAST 200/200 WITH THE SC, HEADERS, EXHAUST, AND 7-8 PSI.

please forgive my ignorance but what are the differences between the centrifugal and easton based sc's?? what are the pros and cons of both?

THE REASON WE MAKE BOTH CENTRIFUGAL AND EATON KITS IS TO COVER THE NEEDS OF DIFFERENT ENGINE/VEHICLE REQUIREMENTS. A CENTRIFUGAL BLOWER (LIKE A TURBO) SEES AN INCREASE IN BOOST AS RPM INCREASES, BUT IS A BIT MORE EFFICIENT THAN AN EATON. HOWEVER, AN EATON GIVES FULL BOOST IMMEDIATELY FROM OFF-IDLE RESULTING IN LOW RPM AND MID RPM POWER UNAVAILABLE FROM A CENTRIFUGAL DESIGN. THE KA24DE HAS LITTLE LOW RPM TORQUE, SO IT BENEFITS GREATLY FROM THE INSTANT RESPONSE. AN AUTO TRANS CAR WILL BE AMAZING WITH THE EATON. THE SOHC KA24 IS THE OPPOSITE. IT WAS ORIGINALLY A TRUCK ENGINE AND THE HEAD WAS DESIGNED FOR MAXIMUM TORQUE AT LOWER RPM, NOT HP. THE CENTRIFUGAL BDT WILL GIVE TREMEDOUS POWER INCREASES AT HIGHER RPM WHERE THE N.A. SOHC JUST FALLS ON IT'S FACE. I HAVE OWNED A NISSAN TRUCK KA24, AND IT COULD PULL A STUMP OUT OF THE GROUND, BUT AFTER 4K RPM IT WAS DEAD. SO THE BDT (BELT DRIVE TURBO) WILL REALLY COME ON AT 3K RPM TO GIVE INCREDIBLE HP AT THE TOP END. THE EATON IS 58% EFFICIENT OUT OF THE BOX. RACE PORTED THEY REACH 70% AE, AND THE BDT IS 78% AE. AE IS ADIABATIC EFFICIENCY, WHICH IS DETERMINED BY WHAT PERCENTAGE OF THE HP THAT TURNS THE BLOWER CREATES HEAT VERSUS HOW MUCH BOOST IT CREATES. ANY BLOWER THAT IS 50% AE SPENDS HALF OF THE CRANK POWER MAKING HEAT, AND THE OTHER MAKING USABLE BOOST. A UNIT THAT IS 75% EFFICIENT USES 25% TO CREATE HEAT, AND 75% TO MAKE USABLE BOOST. THIS MEANS A UNIT THAT IS 75% AE WILL USE MUCH LESS LESS CRANK HP TO TURN IT WHEN COMPARED TO A BLOWER OF 50% AE. TO FULLY UNDERSTAND THIS, WE USE THE FORMULA CFM X PSI / 229 / AE TO DETERMINE THE CRANK HP USED TO MAKE BOOST. LETS LOOK AT THE KA24DE MAKING 8 PSI. 350CFM X 8 / 229 /58 = 21 CRANK HP. NOW LETS LOOK AT THE SAME SETUP PORTED TO 70%AE. THAT IS 17HP. NOW LOOK AT A BDT @ 78%AE WHICH IS 15.7HP. WHILE IT IS NOT THAT MUCH DIFFERENCE, IT IS STILL FREE HP YOU GAIN FROM PORTING AN EATON. THEN THERE IS THE FORMULA FOR HP LOST TO HEAT, WHICH IS ABOUT 1HP PER 10 DEGREES.

Also I read in an earlier post that you were planning on adding additional injectors to handle the extra fuel. But you were also wanting to make the sc's alcohol injected. Where do u plan on puttin all the new injectors?? just curious about this because I love the idea of sc's but dont want to have to install an intercooler as well

MY PERSONAL FAVORITE WAY TO ADD FUEL IS ADDITIONAL INJECTORS. WHILE IT DOES NOT APPEAL TO EVERYONE, IT IS STILL A GREAT ALTERNATIVE TO LARGER INJECTORS AND A MODDED ECU. ONE EXTRA INJECTOR ON EACH RUNNER IS BEST, BUT A SINGLE INJECTOR PLACED BEFORE THE TBODY ON THE CAI PIPE ALSO WORKS. THE LATTER DESIGN IS USED BY TRD ON ALL THEIR DEALER INSTALLED EATON KITS AS OF LAST YEAR.

ALCOHOL INJECTION IS NOT ONLY FOR THE BENEFIT OF ADDING 140 OCTANE FUEL, BUT FOR EVAPORATIVE GASSEOUS INTERCOOLING AS WELL. WHEN ALCOHOL AND WATER ARE MIXED AT A 50-50 RATIO, THE FLASH POINT (TEMP ANY LIQUID STARTS TO EVAPORATE) OF ALCOHOL IS 32 DEGREES F, AND WATER IS 212 DEGREES F. THESE COMBINE TO GIVE A FLASH POINT OF OF 122 DEGREES. WHEN INJECTED AT HIGH PRESSURE AND FULLY ATOMIZED, THE W/A FLASHES THE MOMENT IT SEES 122 DEGREES. THIS OCCURS EITHER IN THE IC PIPES OF A TURBO OR BDT SETUP BEFORE THE MIX REACHES THE TBODY, OR AS SOON AS THE MIX ENTERS THE TBODY PLENUM JUST BEFORE THE ROTORS ON THE EATON. SEVERAL THINGS TAKE PLACE. THE ROTORS ARE COOLED AS WELL AS THE INTAKE MANIFOLD--SOMETIMES TO THE POINT WHEN ON A DYNO THE INTAKE MANIFOLD IS COLD TO THE TOUCH WHILE THE ENGINE IS SEEING 10+ PSI. USING THE FACT THAT COLDER/DENSER AIR MAKES MORE POWER, IT IS EASY TO SEE WHY W/A WORKS SO WELL. N20 FLASHES AT -20F, AND THAT INCREDIBLE COLD/DENSE AIR IS WHAT MAKES NITROUS SO EFFECTIVE. W/A USES THE SAME PRINCIPLE. THE SECOND BENEFIT IS THE COMBUSTION CHAMBER IS STEAM CLEANED SO WELL CARBON DEPOSITS LITERALLY MELT AWAY WITHIN A FEW WEEKS OF W/A BEING INSTALLED. THE THIRD BENEFIT IS FROM THE EXPANSION OF THE W/A MOLECULES WHEN THEY TURN TO VAPOR. THIS RAISES CYLIDER PRESSURES WHILE AT THE SAME TIME COOLING THE CYLINDER. BOTH ADD POWER.

Thanks for the such kind words, you wouldnt believe how hard it is to find that kind of support sometimes. I cant wait to get one of these kits for myself. I am glad that I was able to help get the word out about your product, and I am glad that you made sucha a awesome product. Once again thanks for the support.

[AZhitman]

Tom, let's do this, so we don't piss off any of the sponsors:

1) Let's get you set up as an "official" sponsor of the forums (we'll talk via email).

2) Let's see about getting you a new CAPS LOCK" key.

3) Let's set up a seperate thread for marketing the SC kits for the KA.

[Cholos_D]

<--- I'm stationed at Shaw AFB in SC. What kind of military discount are you talking. And yeah, I'm in the Air Force. I know it's not the honorable Marines , but this time last year I was getting mortared daily on the most attacked military installation in the world...It's not the "Chair Force" anymore!!!

+1 for an eaton when can i order?? thanks for all the helpful info. I agree with you on the extra injectors its much easier to control than using larger injectors. I just have a couple more questions on alcohol injection. 1. Where do u plan on storing the tank? Or do you plan on converting the washer fluid tank?

2. How often would you need to refill the bottle? Since its constantly being used how fast would you burn through say 1 gallon.

I was wondering the same thing.

YOU CAN ORDER THE KIT TODAY. PLEASE LOOK THROUGH THE POSTS TO SEE MY WEBSITE AND CALL ME. THIS IS NOT THE PLACE TO DRUM UP SALES AS GREG ASKED. WATER INJECTION IS ONLY USED AT FULL THROTTLE. A 1/2 GAL RESERVOIR COULD LAST YOU WEEKS IF YOU ONLY USE BOOST OCCASIONALLY. MOST WW RESERVOIRS ARE 1 QT. YOU MUST ALWAYS MOUNT THE TANK LOWER THAN THE INJECTOR SO SIPHONING NEVER HAPPENS. INSIDE THE FENDER WELL IS A GOOD PLACE--WHEREVER YOU FIND A SPOT. ON A HOT AND HEAVY DAY WHEN ALL YOUR BUDDIES ARE RACING YOU AT THE TRACK, YOU COULD GO THROUGH 1.5 GALLONS OF W/A. WINDSHIELD WASHER FLUID IS A CHEAP ALTERNATIVE TO MIXING YOUR OWN. IT HAS ABOUT 30% ALCOHOL. THE SWITCH THAT TURNS ON THE W/A IS ADJUSTABLE, SO YOU SET IT AT 2 PSI BELOW MAX BOOST. THAT WAY IT RARELY COMES ON DURING NORMAL DRIVING. I USED TO MAKE STAINLESS OR ALUMINUM TANKS THAT HELD 1 GALLON, AND ON A TT CORVETTE MAKING 1000+HP WE FILLED THE TANK ONCE A WEEK. AT THE TRACK, WITH RACE FUEL, NON-INTERCOOLED, AND BOOST AT 18 PSI WE WOULD GO THOUGH A QUART EACH RUN. I MIX MINE 50-50, WITH SEVERAL DROPS OF RED AND BLUE FOOD COLORING. THIS MAKES IT PURPLE POWER JUICE IF ANYONE EVER ASKS YOU WHAT IT IS :-)

^ How can anyone not like Tom?

Good stuff, Mr. Knight!

[s13satch]

Will the belt for the Eaton SC work on cars without the factor crank pulley?

and

What is the approximate installation time for the complete kit?

[hybrid_flyer]

Y. WATER INJECTION IS ONLY USED AT FULL THROTTLE

does that mean i have to loosen the lead foot cuz I am at WOT a lot?? Also what kind of alcohol is used?

yeah and the other question was already asked how long for install time, for a decent mechanic (which i like to think I am)?

[SCMASTER]

THE CRANK PULLEY SHOULD REMAIN THE STOCK SIZE. AN UNDERDRIVE PULLEY WILL SPIN THE EATON SLOWER MAKING LESS BOOST. INSTALLATION SHOULD TAKE 10 HRS OR SO. REMOVING THE LOWER MANIFOLD IS THE FUN PART. ONCE THAT IS REMOVED, IT GOES PRETTY FAST. THINK OF THE W/A LIKE YOUR FUEL TANK. IF YOU RACE AN IMAGINARY FOE AT EVERY STOP SIGN, EVERY STOP LIGHT, AND EVERY TIME YOU DRIVE YOUR CAR, WHAT MPG WILL YOU GET? 8, 10, MPG AT BEST? SAME FOR THE W/A AS WELL AS YOUR EATON BLOWN CAR. REMEMBER THAT AT 7 PSI YOU EFFECTIVELY RAISE THE ENGINE'S DISPLACEMENT 50% FROM A 2.4 TO A 3.6. AT FULL THROTTLE A 3.6 WILL USE 50% MORE FUEL THAN A 2.4, AND THE REAL BENEFIT IS YOU ONLY HAVE A 3.6 WHEN YOU FLOOR IT. THE REST OF THE TIME YOU GET SIMILAR MILAGE TO STOCK. USUALLY IT IS 1/2 MPG LESS THAN STOCK. THE EATON USES 1/3HP TO SPIN IT WHILE CRUISING, SO IT IS NOT A PARASITIC DRAG ON THE ENGINE. ANOTHER REASON FOR THIS EATON KIT WAS TO REPLACE AND COMPETE WITH THE COMMON SR20DET SWAP. MOST JAPANESE ENGINES HAVE NO DOCUMENTED HISTORY, SO IT IS ALWAYS A GAMBLE WHETHER IT IS DECENT MILAGE, HAS A GOOD TURBO, ETC. THE HASSLE OF TRANSPLANTING A SUPPOSED 40K LOW MILAGE SR20DET JDM ENGINE, AND THEN FINDING OUT THE TURBO IS BAD, THE ENGINE HAS A SLIGHT KNOCK, ETC IS FAR TOO COMMON. A WEEDEND PROJECT TURNS INTO A SIX MONTH NIGHTMARE AS YOU REMOVE THE NEW ENGINE, GET ANOTHER ONE, REPLACE OR REPAIR IT, ETC ETC. I WENT THROUGH THIS MANY TIMES WITH JDM ENGINES. THE BS AND FRAUD PERPETRATED BY THE JDM ENGINE IMPORTERS IS HORRENDOUS. NOT TO SAY THEY ARE ALL BAD PEOPLE, IT IS A SIMPLE FACT THAT JDM ENGINES CAN'T BE DOCUMENTED FOR MILAGE. ONCE DETERMINED THAT THE VEHICLE IS 'UNREPAIRABLE' BY YHE JAP GOVERNMENT, THE CAR IS IMMEDIATELY DISSASSEMBLED AND WAREHOUSED WITH NO REGARD FOR MILAGE, REASON FOR UNREPAIRABLE STATUS. ETC. THE IDEA THAT JAPS ONLY DRIVE 4-5 K/YR IS INSANE. A 20 YR OLD ENGINE COULD EASILY HAVE 250K ON IT. WITH THE ORIGINAL KA24DE, YOU KNOW EXACTLY THE MILAGE. YOU COULD REALISTICALLY HAVE THE KA BUILT WITH FORGED INTERNALS, INSTALL THE EATON, AND HAVE 350HP/350TQ WITH UNBELIEVABLE RELIABILITY. SO WHAT IF YOUR JDM SR20DET HAND GRENADE MADE 450HP FOR SIX MONTHS BEFORE IT TOASTED? YOU SPENT $3K ON THE TURBO AND FMIC/PIPES UPGRADE, , $3500 FOR THE JDM SWAP, AND NOW HAVE A USELESS VEHICLE. THE KA WILL RUN 12 PSI ON A BUILT ENGINE FOR 150K MILES, AND YOU LITERALLY WONT BE ABLE TO KILL IT. IT SHOULD RUN HIGH 11'S, AND DO THAT WITH A/C, FULL INTERIOR, AUDIO AT FULL BLAST, ETC. WHILE THE SR20DET GUYS ARE TRYING TO FIX THEIR CAR FOR THE 200TH TIME THIS MONTH, YOU DRIVE OFF WITH YOUR BABE INTO THE SUNSET LIKE THE HERO BOTH OF YOU THINK YOU ARE :-)

[Bigvinnie]

THIS TAKES ADDITIONAL INERTIA AND CRANK POWER TO ASSIST THE PISTON IN PUSHING THE MIX OUT. THE FORMULA FOR THAT IS {[(CID X RPM/2) X PSI] /396,000} % IN/EX PRESSURE RATIO. SO LETS DO SOME MATH.180CID X 6000RPM/2 X 10 PSI/396,000 /1:2.7. THIS MEANS WE ARE LOSING 35HP TO BACKPRESSURE. NOW WE LOOK AT AN SC. THERE IS NO PRESSURE AFTER COMBUSTION, SO WE ADD THIS POWER TO THE FORMULA.180 X 6000 X 10/2 /396,000. SO WE GAIN 13HP JUST FROM THAT. SO NOW WE MUST CALCULATE THE ADDITIONAL HP LOSSES FROM SPINNING THE SC.PSI X CFM /229/AE OF SUPERCHARGER. 450CFM X 10 PSI / 229 /70% AE = 28 HP + 2HP BELT FRICTION LOSSES. SO WE HAVE A 30HP CRANK POWER LOSS WITH THE SC, BUT WE SUBTRACT 13HP FROM THE INTAKE STROKE PISTON PUSH WHICH MEANS THE SC ONLY USES A NET 17 CRANK HP. THE TURBO LOSES 35HP-13HP, OR 22HP TO BACKPRESSURE. SO WHY DO TURBOS MAKE MORE POWER? USUALLY BECAUSE THEY ARE INTERCOOLED WHICH RAISES THE AE, AND USUALLY BECAUSE THEY RUN HIGHER BOOST.

Im still abit lost in your equation. It makes perfect sence to the calculation that you used for power loss. But not one engine is equal to another. What I mean by this is pulley dampening systems in which some pull more degredation loss than others, and to where some dampening systems can be more effecient in delivering power that could of been lost. There are other instances into the size of the pulleys in which there is the stock crank Pulley to size X of the S/C. There are also harmonic ineffeciencie's that should be discussed adding aditional belt driven components to the crank assembly (which dampening plays a key roll. You would think that as RPM's increase this only effects dampening, to the instance that when RPM increases it only disturbs or agitates the the harmonics of the crank. You did state that after a awile it is a trade off at 14 PSI between turbo charging to S/C, would this be the reason?BTW I saw a cobalt ss run a 15.1 in the 1/4 mile not bad for a stocker S/C on a mildly 90* weather day, humidity sucked as well (this was at infineon raceway on wednesday).This super charged car runs a 14.6, 1/4mile time on good days. Thats better than a stocker silvia sr20det on stock boost (7psi) runs a 14.9 on good days.

THE TYPICAL SERPENTINE BELT LOSS IS 1-2 HP AT MAX POWER. WHETHER THE CRANK HARMONICS ARE DAMPENED BY THE PULLEY OR NOT WONT DO ANYTHING DIFFERENT TO THE ENGINE WITH OR WITHOUT A BLOWER. THE HARMONIC BALANCER WILL HAVE BEEN DESIGNED TO OFFSET BELT SLAP AND CRANK HARMONICS, SO ADDING AN EATON WILL NOT CHANGE THAT AT ALL. WHILE EVERY ENGINE REACTS DIFFERENTLY RO BOOST, ALL CAN USE THE SAME FORMULAS FOR APPROXIMATE FLOW LOSSES, AND HP GAINS. THE FORMULAS I QUOTE ARE STANDARD THERMODYNAMIC EQUATIONS, AND WILL BE FOUND IN ANY ENGINEER'S LIBRARY. THE REASON A TURBO STARTS TO PULL AWAY AT 14 PSI IS BACKPRESSURE LOSSES VS CRANK PULLEY HP LOSSES. AT LOWER BOOST THE BACKPRESSURE ROBS A HIGH PERCENTAGE OF POWER, WHILE A BLOWER IS AT PEAK EFFICIENCY. A BLOWER'S EFFICIENCY WILL DROP AS BOOST INCREASES, WHILE A TURBO'S EFFICIENCY IS LEVEL SO BACKPRESSURE LOSS WILL BE 100% LINEAR. THIS MEANS THE HP TO TURN THE BLOWER IS EXPONENTIAL, AND THE TURBO LOSSES ARE LINEAR TO BOOST. ONE BENEFIT TO A TURBO IS THAT YOU CAN LESSEN THE BACKPRESSURE LOSS RATIO WITH BALL BEARING TURBOS, LARGER AND MORE PROPERLY MATCHED TRIM AND A/R HOUSINGS, ETC. BUT FOR THE SIMPLICITY AND DRIVABILITY ON A DAILY DRIVEN STOCK VEHICLE, IT IS HARD TO BEAT A SUPERCHARGER.

[s13rb25det]

any more news on these kits? were can I view the finished product?

[TravisD]

I went to the website, and all I saw were electric superchargers.

[s13rb25det]

yeah I only saw electric superchargers also! cant find them with a google search either

[SCMASTER]

Orders can be placed through my website, but ultimately there will be a dedicated website directed at only Nissan sc kits, etc. My boosthead.com site will be a temporary location for orders of the Eaton KA24DE kits. It will allow for paypal payments, etc. You may wish to phone us at 786-243-2000

[JesusLikesKFC]

how much will u be charging for a base kit eeaton? whats involved? i know somebody who is very interested. Also have to admit this really is getting my attention too. Checked your site and only came up with electric/ alternator belt driven centifugal type.

[7anshin]

Forgive my ignorance here but I want to learn… What is the difference power wise between the belt driven turbo and the belt driven supercharger? (Yes I understand that superchargers are belt driven and a turbo is usually driven by the exhaust gasses, I want to know the difference in power loss/gain, torque/loss gain… All the average this is better than this because of *blank*. BD vs BD)

If this has been covered in this post all ready, forgive me. I tend to forget, and it seems as if I have been reading this post for ages.
