I want to keep my current cam and add a turbo, can I?
I found a local shop that is going to build me a single turbo kit for my 05 GTO and I would like to keep the cam that's in it. It's a 242/248 .621/.615 on a 111. I know the conventional wisdom says grind it on a 114+ for a turbo, but I've run aircooled VW turbo setups that were ground on a 109-110 and they absolutely screamed.
What gives?

Here's the results from a TT setup we tuned that everyone said would not work due to the cam not being 'correct' for a turbo car.

Could it have maybe made more power with a different cam, well maybe, but check the numbers, there was no shortage of power anywhere.
As it sits right now, that car is running a cam not designed for a turbo set up, and to make it more 'unconventional', he is running 2.73 gears out back, and the cam is recommended for 3.73-4.10 gears optimally....

Amen to that.

Go for it man. I have a TSP torquer 3 (231/234 .643"/.598" 112 LSA) cam in my car with patriot stage II's and on 6 psi it made 590rwhp on a mustang dyno w/ a TC76! Through a six speed of course and I am only revving it to 6,000 to save the motor. The power curve doesn't look typical of a turbo car because the power and torque keep on climbing all the way to redline!

The way the shop is going to do the kit it won't be much of an issue at all to swap the cam once the kit is in and running. If it sucks, I'll change it. It will most likely suck, but I'm a curious kind of person and I want to see what it will do with the current cam and with a different one. That way I can post up and tell everybody about my experiences with a non-optimal big overlap cam, and one that a sponsor specs out for me.

Like I mentioned previously, the other turbo experience I have is with aircooled VW's. We always ran huge durations and overlap. The power hit around 4000-4500 and we shifted at 8000. With the correct converter setup I really won't care if I'm loosing anything less than 4000rpm.
