Vortech Supercharger Installed!!!!!

[kmech_7]

Well i got it in......i am so happy!! i cant wait to show it off... we should get another meat together in San Diego ASAP. I have 6 guys that also want to get together from work...3 g35 owners and 3 350Z owners.

[audtatious]

Congrats. How do you like it thus far?

I would post a thread in the CA Regional forum concerning a meet.

[2mhighside]

Good job! when do we get to see pictures and some numbers?

[gwoods]

I'm a big fan of supercharging vs turbo charging. You give up some power to turn the pump but the pay off can be bigger!

Can't wait to see the numbers! Should be a 40-50% increase in power across your band!

Actually, it's pretty well known that a properly designed turbo system will outpower any supercharger system currently out there boost for boost, motor for motor. Turbocharger efficiencies are higher than positive dislacement chargers. while centrifugal supercharger efficiencies can theoretically be the same, the step up gear design and the fact that it is mechanically connected to the crank means that boost increases in a linear fashion with the engine speed. So at say, 4000 RPM, the turbo can already be at peak airflow while the centrifugal supercharger might be as low as half the peak boost.

Add to that the exhaust driven turbine frees up the crank allowing for a measurable advantage over a supercharger. Turbos do have higher backpressure in the exhaust, but if sized properly, it will be quite minimal.

The comparison is much more complicated, of course, but for all intents and purposes, turbos can easily outpower superchargers.

Pretty well know to everyone but me

I like superchargers more, if turbos were so much better funny cars would run a turbo instead of supercharger right?

I actually like nitrous better then either cause its cheaper initially and easier to adjust for power. Nitrous is only putting additional stress on your drive train when you use it and you can just use enough to win

But that just my opinion to each his own.

IF I put a power adder on my G it would be nitrous, if I didn't do nitrous I would do a supercharger, turbo is bottom of my list but still a COOL mod and big props to anyone running any kind of power adder!

Actually, Top Fuel Dragsters and Funny cars don't use turbos because they were banned.

According to SCC magazine:

"In the early 80's, the domestic performance turbo guru, Gale Banks tried to develop a turbocharged Top Fuel Dragster. Even with only 20 percent nitromethane in the fuel (a 90 percent mixture of this powerful, nearly explosive oxidizer was typical at the time for Top Fuel racers), the engine developed so much explosive power that the drivetrains at that time could not contain the power. The team lacked the money to fully develop the concept and soon the NHRA banned turbochargers from Top Fuel before a real, well-funded turbocharged team could come upon the scene. "

Problem with nitrous is that they are not generally friendly for road coarse racing. It's generally on/off, which means less ability to modulate throttle on corner exits. There are staged systems available that can be tuned based on throttle position, but there are still stair steps of power. It's definitely not ideal.

Superchargers will put a constant load with any internal compression it performs as the crank will always be turning the supercharger. Turbos however, aren't under the same stress as cruising would only be as stressful as the backpressure the turbine provides. At low airflow, itshould be minimal.

The limitation to nitrous is that it will always be limited to the amount of atmospheric pressure available unless it is used in conjunction with a turbo or supercharger. This means that theoretically, it is limited to the displacement of the cylinders themselves (where turbos and superchargers increase the pressure/density of the air allowing cylinders to be filled with more oxygen molecules). From my understanding of Nitrous, it is further limited by the fact that you need some percentage of atmospheric air content in the cylinders to start the combustion process so the Oxygen atoms can be released from the nitrogen atom.

hey just curious, can u add an intercooler and a blow off valve to it? I had a civic b4 my G and with the vortech you were able to put both on. THanks

[C-Kwik]

I know the Vortech kit has an intercooler. I would suspect it would have a blow-off/bypass valve too as compressor surge would be of concern.

[gwoods]

interesting, I still like superchargers better then turbo charger.

I like to 1/4 mile race (less skill involved ) so Nitrous meets my needs and the bang for buck can't be beat!

[joe603]

Congrats! I expect to see pics ASAP!!

Turbo for the VQ35 will give you more power, but it is a very difficult install. A supercharger is something you can do in your garage with hand tools. If you install it yourself, you save thousands of dollars...this is the benefit of a supercharger VS a turbo for me.

Make sure to tune it properly by a good shop, and post some dyno #'s!

[kmech_7]

yes my system has an intercooler and a blow off valve. also came with an FMU, EMU, and fuel pump....any other questions?

for this car in california you have to use a supercharger. the VQ35 motor is not legalwith Turbos. so it was either Stillen or Vortech. NO turbo system is carb legal here. bummer.

[adren77]

How long did it take to install?

Turbo kits, particularly for the G35 do take longer to install, but it is certainly a project that can be tackled at home.

On the other hand, the Turbonetics kit is supposedly pretty simple to install.

[kmech_7]

ok....here is the pics of my supercharger(vortech) install.



enjoy

Sweet! can't wait to see the numbers.

It would be really cool for me to put at SC on my Sedan... No one would ever know... and you could beat just about any other sedan on the road.

Do you think it would run with E55 AMG or M5?

DJ

[kmech_7]

yes it can run with the E55 amg. the benz goes from 0-60 in 4.5. mine goes in about 4.1 or 4.2........

i know that in the 1/8 mile i get 7.5-8.0's all the time.

and yes im pushing about 405whp. 475ish at the crank if i did the calculations right.

[Andy_V35Sky_350GT]

If you don't mind me asking, how much did everything cost from in the box to in the bay?

[SVTCOBRA]

VERY NICE!! Would LOVE to have one!

Have had turbo cars, would rather have a sc. just preference

[2mhighside]

Just one question. Do the directions say to install and aftermarket fuel pump underneath and not in the tank where the original one is? My Turbo kit came with a Walbro high flow that required me to make several changes to the stock in tank fuel lift system that would allow for greater fuel delivery. Just somethin to look into. Hate to see ya starve it for fuel and lean out on ya. Cheers and good job.

Nice mod, but more importantly, what part of San Diego do you live in?

[Jacko3]

Very nice! I think at the end of the day, Superchargers are winning out over Turboe Chargers for the Gs. If you plan to keep your car for just 6 years, adding a supercharger should be just fine. My advice is to wait for the engine's warranty to be over before installing a supercharger. A supercharged engine should last as long, but your car will have reduced reliability. Since these cars where built to last 200K, with a supercharger, I think 150K can be achieved. So, why not install one? If you plan to keep your G for much longer than 6 years, NA might be the way to go, only for the reason of increased reliability.

I doubt the G-35 would be a great car to keep beyond 6 years. 6 years is my target date, assuming 20,000 miles a year of driving. There will be a more powerful car and a more beautiful infiniti car, with more bells and whistles, by then. I try to balance risk with pragmatism.

After my warranty is up, in about 3years, I will be gunning for a supercharger, which I will use for another 3 years before selling the car. I am already enjoying the car with NA mods already. I wonder how much more fun a SC will be? What does anyone think of this?

C-Kwik, what do you think?

After spending a weekend underneath my late model LT1 firebird, installing a set of headers, I vowed to never mess with exhaust again! To do a twin system, most shops drop the engine out of the bay...not something most can do in a garage without a lift.

[kmech_7]

Ok, it looks like there are a lot of questions here so im going to try to answer them all....here we go....

1. the compleate system only cost me $4200.00. it retails for $5800.00 but vortech has one of the best military discounts i have ever seen. for all the rest of the crap like oil, plugs, gages, gage pillar, wire, and misc crap the total is about $5000.00 even. i did all my own work as you can see. (i was the guy under the car as my buddy was diconecting my fuel lines.)

2. the fuel pump is to be there under the engine. the directins are very clear on this. this is just an inline pump. from the factory the vortech EMU/FMU are set to run very rich to be extra safe. when you tune this you can lean it out.

3. the warrenty issue is a non issue for me. my car is an '03 coupe with 72,000 when i put this on in dec. plus if you do use this system there is a free warrenty program with it. the warrenty is against any damage to your car if you dont modify the s/c (dont f*** with it) for 3 years!! good warrenty!!

p.s.- i plan on keeping my g35 for many years. i have invested a lot of money into it. about 12K. i think i might keep it for a collecter car in the future.

[kmech_7]

oh ya, i forgot 1 question....

i live in the bonita/ Eastlake area. off of the 805 at telegraph cannon road.

here....enjoy this....more pics of my car....



say what you want its my rac/show car...lol...and everyday driver

[Kenrik]

Supercharge is better for a road course/curves due to the power being in the whole RPM range.

Turbo is better for straightline/highway/open tracks

I prefer the Supercharger...

[TeflonG35]

I like superchargers. I've been going back and forth in my head for some time whether i want to go with stillen or vortech. Both have advantages. Vortech is more like a turbo so it has a nifty Blow off valve. But stillen gives alot of power sooner, No spool up lag, and is sold in stages. So it is easier to save up for. But stillen you have to use a cowl hood with.

[Jacko3]

kmech_7:

When i grow up, I am going to be like you---iinstall a Vortech Supercharger.

[G_whizz]

man... I REALLY envy you... car's hawt bro!

[USAF_G35_Guy]

Hawt dude!

I agree with Joe..screw workin with header lol..I've already got aftermarket so I might as well keep em and go SC. I think I just may have to do this instead of ST. I've been thinking about all types of FI for awhile and definitely don't wanna do TT cause IMO...it's just more stuff to go wrong. So, does anyone know how a SC does with a 50 or 100 shot of NOS?
