Is that a bad idea or something?

supercharger maybe, turbo no.

there are plenty for 5.5 psi........they are the guys who just installed their greddy kit and are running around on the stock wastegate springs. 10 minutes later, they have a boost controller hooked up and are runnign 9-10 psi with no problems whatsoever.

Well, I was looking into that as a less expensive alternative to rebuilding the engine to run 400+ WHP.

I don't see a problem with it, but if you decide to go for more power down the road you might regret it. I agree with Nexx though on it only being a good idea if you have a supercharger as a turbo will have more bottom end power. I have considered it but I will need to get my traction issues worked out first!

just run 400hp on the stock block and you will be fine...

ive thought about it with my current setup but idk?

But I thought it was the turbo that had a better top end and the supercharger that had a better low end?

Nope it's the opposite and turbos more than often have the same top end too. You might be getting confused as there is more "instant" power with a supercharger as a turbo takes a bit to spool. Because of the lower torque of a supercharger you can safely run more top end power on a stock block and the gears would be a good way to offset their lack of low end torque. I think there was someone on here that did 4.08 gears with a supercharger.....

I have under 400 on a DD and it spins 1st and top of 2nd consistently below 65 degrees. It might be useful if it is always hot where you are, but I see you are in MD

I am running 3.9 gears with my Vortech setup and it works well for me. But, I don't have near the torque of a turbo setup.

Sentry is also running 3.9's and ZNickZ is running 4.083's. I agree with the others though they work with a supercharger, but they are NOT ideal for a turbo setup.

How does that feel? I would imagine doing gears with my setup, a camber adjustment and some better tires would liven things up quite a bit.

Generally speaking, a positive displacement supercharger will have better low end than a turbo, but a centrifugal supercharger will not. In fact, the turbo kits made for our cars generally outperform the centrifugal superchargers for the VQ platform across the entire rpm range. Most of the SCs I see posted here are the centrifugal type.

I think Stillen does make a small positive dispacement SC for the VQ, but I don't know how well it performs. Based on its general lack of popularity, I would assume that it also does not perform any better, or perhaps performs worse, than a good turbo kit in the low rpms, and certainly won't perform better in the high rpm range. I have not seen anyone here in the forum use a good strong positive displacement SC on the VQ, though it would be interesting to see. There is some discussion on SCs in a thread relating to twin-charging I started a while back. You can probably search on the term "twin-charging" and my screen name and find it if you are interested.

Also, one more thing to note; a SC requires mechanical energy direct from the crank to operate, thereby eating up some of the hp that is produced. In other words, you will be pushing the motor harder to get the same whp numbers in comparison to a turbo setup. Turbos extract energy from the exhaust gases, so they really don't take any additional hp to push (ignoring the effects of back pressure). The centrigugal SCs probably don't take a whole lot of hp to drive, but the large positive displacement SCs certainly do.

I think that the gears and the Vortech compliment each other I am running a 295 tire and I can still hook up part way through 2nd. I can take you for a drive one day if you'd like...just pm me.

did u drive the car before with the vortech and stock gearing or just with the gears from the start? curious if you feel the car is really any faster or just seems it or what you really feel about it in a comparison

Dude! I didn't even realize you are in Columbus until now. I will def. take you up on that. I'll pm ya. Thanks man!

I had my 4.08 gears before the vortech so I honestly dont know what a vortech setup with out it would feel like. The gears compliment the SC nicely though. It allows me to rev higher, faster, which in turn gets me into boost faster. I am very happy with the power I am at now. With the gears, some breathing mods, a smaller pulley, and 275's in the rear I definitely have a hard time hooking up till late 2nd gear, but that combo is amazing for highway pulls ,which is always a good time
