i was just wondering what's your HP/torque with Comptech S/C, IHE, etc... done. RWHP if you have it. can you have it a little over 400 crank, say 420-450?

tnx

 

my SC whp post

 

350/200 with just an exhaust. I guess its about 400 to the crank.

 

I wouldn't discount the EMS and larger injectors, 'cause you ain't getting 350 w/o 'em! In fact, I'd be interested in what fuel pressure you have to run to get those 550's to do the job.

 

Assuming a 20% loss from crank-to-wheels, 450hp would net you 360 at the wheels. That is doable. Which dyno you get that on matters a bunch, too.

 

I think I misread what he was actually asking. With just the stock pulley, stock header, test pipe, and exhaust I was about 300/175.

The gauge on my fpr reads 40psi at idle.

 

I got 300 whp at 5 PSI of boost. Thats the stock pulley. Also had Comptech header and exhaust.

 

This is the number one thing to consider when you are compairing numbers. I can say that I got 320whp/191tq on just about the same setup OyATL is running and that sounds rather low to his. But considering that it was on a dynojet and I assume that his was done on a dynopak (if not you are my hero ), they are really close. And when you are figuring crank hp...it's around 15-18% higher than dynojet numbers...not dynopak numbers.

Edit: Nevermind I though he was running a vortech...a comptech running 10psi will net larger gains than a vortech at the same boost level. Dems' really good numbers OyATL

 

Boost is boost. How can the one supercharger make more power than the other if the only thing that counts is boost??? Nobody has measured the power necessary to run the snail. Please enlighten us.

 

What do people dyno at with the stock vortech kit? This has been argued forever now.


I did 315/202 with 6.6lbs on my comptech.
