Q45 Supercharger Project: From Conception to Reality.

[MJC]

Like I said... it increases flow.

What allows it to flow more air to make the same psi? The efficency of the larger compressor. Again it's symantics, I know what you're saying and you know what I'm saying.

[PoorManQ45]

Possibly a larger compression chamber on the larger blower

Nismo Freak:

Thank you for your brilliant posting. You said what we all knew, and explained it precisely. Again Thomas and all of us have known this, and hopefully with your brilliant explanation, this issue can be laid to rest.

It's been argued since 2004, and I don't understand the point.

There is a reason one of the countries most respected supercharger Fabricators works with the M90 and choose it specifically for the VH.

Some people act as if he just picked straws, and think they can do better.

[PoorManQ45]

Ryan: You have to agree that there are multiple roads to reach the same point, correct? SOme just have a few more obsticles along the way.

There's no reason to give anyone grief about suggesting a different route

[350zQ45a]

Whatever works, but I have a real problem with the continual doubting and hating on eaton setups. This should be the end of the discussion. Like Thomas's word wasn't good enough, Nismo freak has put it down on paper yet again.

I'll continue to be devisive as long as people continue to think that people such as thomas are wrong, when they have no experience or clue about what they are talking about, and are disagreeing with people that do this for their livelyhood

PERIOD

[QShip]

As I said before, I'm not looking for a 600whp 2 1/4 ton missle

I am!

My friend, it was not an issue of thinking Thomas didn't know what he was talking about, I've seen even the most seasoned builders and shops make choices I didn't agree with on turbo setups. Who is right or who is wrong is up for debate. Anyways, again, it was not doubting his supercharger expertise, it was more asking for the information that you and Nismo Freak brought to the table, that's it. I offered up the information that I had heard and seen and was hoping someone could set me straight, and you guys did. Nothing more, nothing less.

I work on forced induction cars for my livelyhood as well. Being an Eaton M90 expert is not a requirement.

In the respect of Thomas' word, sure he obviously knows what he's talking about...but call me cynical, I almost NEVER take one man's word for something without any numbers or explanation, regardless of the person. I hope you don't see this as an insult to him or anyone else, I'm just a 'make me believe it' type of person. Maybe the topic had been discussed and proven prior to this thread as you suggested, it was just before my time on this forum. So please stop trying to think I was trying to discredit someone's work or ideas, I was just looking for the data that you all presented me with.

All is well.

[450zxtt]

as usual,such passion discussing this boosted q thing...heres an idea...do the job.its obviously not that deep.450zxttvh45dett power baby

[jamesmost]

Yes _ who is # 1 - surely the rest will follow I am certanly abord the ship

[350zQ45a]

We're working on that. I was going to, but I just got tired of the Q. One day I loved it, the next I hated it.

Wes will get 'er done

[jamesmost]

i was under the impression that Wes was bowing out for the moment

[elwesso]

Negative, im still gonna be number one but the project will not be completed as soon due to my lack of funding.

[rsiwicki]

don't worry Wes...If I hit lottery then I will just drop off my car at Thomas Knight's place and let him have a go at it since he is only 50 miles away.

[jamesmost]

rob if u hit the lottery after u buy youd Bentely coupe i expect u to supercharge Wes ride as well as mine b**ch

[350zQ45a]

rob if u hit the lottery after u buy youd Bentely coupe i expect u to supercharge Wes ride as well as mine b**ch

+1

[QShip]

You guys are all wrong...

Rob will boost my Q and my Titan!!

[Death by Mullet]

Negative, im still gonna be number one but the project will not be completed as soon due to my lack of funding.

work nights, steal, what ever it takes, I want to see this supercharge thing moving.

[NICORPS-Q45]

I think what I'll do is take out a loan so I can get this done with all the proper modifications to the car so I can get 500whp safely. That's my plan anyway, it's just a little way off because of having to move into an apartment and planning on getting married next summer.

[1993TanJ30]

So no new progress, right?

Funds holding this up... I wanna see this already!!! And see some dyno slips!

[heywier427]

ive been watching this forum for a while anticipating something...anything. if it is funds holding this up, how much is needed. id donate to the cause, and id have no problem trusting wes with my money. money's tight for all of us. youd be buying a well documented install on a future purchase. seems worth it to me. id love to print out a step by step supercharger install with all parts n pieces listed. how nice does that sound?

[slownslurious]

its cheaper (lots cheaper) more reliable, and with some cheap n' easy mods it can be made just as good as the 112.....

Possibly, but won't that require spinning it faster and heating up the intake charge more? Another issue to consider is that a smaller blower can build more pressure on a smaller motor (ie the 3.8). PSI is pounds per inch, increase the volume of the area the supercharger is pressurizing and if nothing else changes, the pressure will decrease. Thats why v8's have to use larger blowers to reach the same boost pressure. I don't doubt the ability of the M90 to reach the low boost setup you guys are going for, but I think you are gonna have to be spinning that pulley pretty fast, and then you have to start worrying about blower longevity, belt slip, and excess heat.

Quote »112s generally go for like $500+ on ebay and the 90s go for 100-200... With race porting and such low boost, the choice is obvious!!! We're not going to be able to go above like 8 PSI due to the injectors... I think 6 is about the most ill go, im going to start at 3..[/quote]I have been shopping around for a while and I noticed that while the older uncoated M90's off Tbirds etc certainly go for those prices, the newer ones with teflon (or even the mid 90's ones with epoxy) coated rotors are a bit more expensive (average selling price seems to be $275 and up). I found an 03 cobra blower (m112) for a paltry $250 bucks, which was actually less than a 94 thunderbird teflon coated blower that I was also looking at. Just something to consider.

Quote » Thomas has said that intercooling is definitely ont worth the money on this setup, as a W/A setup would be perfect and very inexpensive... When it runs out, just pull over and put some more water in there!!! [/quote]if I was porting and speeding up the M90 I might be concerned about heat without an IC... water and alcohol might do the trick but if it runs dry and you forget to fill it you might be in for a nasty surprise next time you floor it on a hot day.

So, anyway in conclusion I was checking out some efficiency charts for the different blowers and thinking that an M112 might be a better choice as the M90 just seems a little bit undersized to me.

[ZedZillaZ32]

is this still being worked on r has the project gone dead?

[elwesso]

Someone just needs to step up to the plate to be #1

[PoorManQ45]

Wes: I've got a VH you can have

[redmanfx]

Hmmm.. the engine would still have to be tuned correctly and how would we get that done? Who would do it? I didn't see a solution to what Allan said about needing something more than the off the shelf JWT Tune.

[elwesso]

For those that only race their cars and want every last HP out of their car, then yes youll need more than the one size fits all JWT tune.

However, the JWT tune probably only holds back 10% of the HP, and in return you have the safety factors that:- the car will probably never detonate- You wont run out of fuel- the car will never detonate..- you can run the car on pump gas- the car wont detonate

WHY DOES EVERYONE INSIST ON MAKING THINGS SO HARD. DONT FOCUS ON THE END PRODUCT, FOCUS ON THE STEPS. GET THE STUFF WORKING, THEN TWEEK IT TO MAKE IT WORK BETTER!!!!! BECAUSE NO MATTER HOW GOOD YOU DO IT THE FIRST TIME, YOULL STILL NEED TO TWEAK IT...

The point is, the JWT ecu will get the car running in good fashion and as soon as you want, you can retune the car....

Its no wonder theres no boosted Qs since everyone trys to make things harder than they are!!! WHO FREAKING CARES IF YOU BLOW A MOTOR, YOU CAN GET A NEW ONE FOR A GRAND!!!! Its probably one of the cheapest nissan motors you cna buy now (besides the KA and VG)

[redmanfx]

Is that attitude I detect young man??? Why must you make me feel like the kid who put his fingers in the monkey cage?

Step back once to the left and let Rover take over! Rut Roe!

MP90 it is.

P.S. A thousand dollars is allot for me. I need to find a sponsor......

P.S.S. It'll be a JDM engine.

[elwesso]

your not the kid who stuck his finger in the monkey cage, your the crazy guy that set seats on fire!

[TBrack]

any news?

[slownslurious]

I'm in the middle of fitting an intercooler caddilac supercharger to the vh. I'll post pics/results if/when I'm done.
