Im planning on putting a vortech supercharger on my coupe. But im a little scared about it because i dont know how much power my motor and tranny will hold.... I dont wanna blow my motor or tranny...

 

I plan on putting the supercharger, bigger injectors, intercooler, bigger fuel pump, and getting it tuned. I already have a cold air intake. Kinetix ssv intake manifold, kinetix highflow cats. And hks hi power exhaust. So all that plus what i wanna put on. Will it be to much?

 

Is it a auto or 6MT? Also, if it is 6MT is it the stock clutch? I have a 04 G35 Coupe 6MT and I just put a vortech supercharger on with the stock pulley (8 psi) about a month ago. From what I read the stock clutch will hold a little more then 300 ft lbs of torque, and I'm pretty sure I have read about people running the supercharger with the stock clutch and being okay, it just may make you wear it out quicker if you let it slip when you romp on it. I have a upgraded ACT clutch so I can't comment on if the stock clutch will hold or not. My stock clutch was holding up to my 4.08 final drive gears with Nitto 555R at the track and I never noticed any slippage so I would say you would be okay to use the stock clutch, especially if you don't have any exhaust or plenum mods. I have full exhaust, MREV 2, and 1/2" plenum spacer and I put down 316 ft. lbs. of torque to give you an idea of where you may be at. As for if the engine will hold up, I would say that mainly comes down to the tune and if the engine is already abused then the boost is just going to speed up the problem. It looks like most people are okay running the 8 psi on the engine, now when they jump to 11 psi(400 rwhp+) or more it starts becoming problems with bending rods and pistions. There are some posts where people are doing 500 on stock engine but how long that engine will last, who knows. Most people don't want to find out. Some engines are just made stronger then others. I did a compression test on my cylinders prior to the supercharger and all my cylinders where right at 185-186 and I'm going to check them again on my next oil change and see where they are at. I have been driving the car hard everywhere I go, watching my gauges so I will see what happens.

 

Ive been running 427whp and 434rwt for about 5 years now with just a trans cooler(large) and the Transgo vb mod and all is well after about 45,000 miles with the Greddy twins.

 

Mine is auto. So u guys think I should do some work to my motor first? I'm guessin ill be around 370 to 410rwhp I've never had a problem with my G. Runs better then when I first bought it. Another thing to is I just hit 70000

 

I don't really need more then. 400 that's enough for me. I just don't wanna slap it on n then have the car break down

 

do more research, but you should be fine. out of the box vortech will put you more at the 350-375 range so you should be fine. you'll need pullies and other supporting mods to get into the upper 300s on the vortech

 

I was guessin id be upper 300s because of the mods I already have. What other supporting mods are u talking about what else would I need? I posted all my mods on the first post.

 

427rwhp/434rwt? besides the trans cooler and the Transgo vb mod(what is that btw?), is the rest car stock? I've always wanted to FI my car but i dont have the money for everything that comes with it :[ so if this could be an <7k setup i would love it! and my car has rediculously high mileage so i would probalby run a small turbo setup for drags, the constant power from an SC might be to much on my engine since its my DD. is your car 5AT or 6MT?

 

Greddy TT setup and the block is stock.The transgo is a valve body kit the really wakes these lazy shifting trans up and when under hard throttle will shift fast and hard.

 

ic... so I take it your main(only) concern with your FI setup was your tranny... ima have to check that Transgo vb mod!
