What Do You Think Of This HP Gain Software?

Hey guys, would you download and play with this bit of free 911 horsepower analysis software from Protomotive. Download and run the file "hpgain.exe".

Edit: Runs in a DOS box. Arrow up/down to move between values, arrow left/right to change values. "Baseline" motor appears to be a NA 3.2.

Do you think it is accurate for NA motors? For turbo'd motors?

Edit: I was impressed at how much HP gain is allegedly produced by relatively low boost. According to the software, just 4 psi gives more HP than increasing displacement to 3.8L (new P&Cs and crank) and C.R. to 11:1.

I was impressed at how much HP gain is allegedly produced by relatively low boost.

When you put a turbo on a high compression engine with a normal cam, the power gain per psi is amazing. The best part is the driveability though. The high compression ratio really helps get the turbo spinning at low rpms.

So this software says the Protomotive stage 1 - 0.5bar boost, stock 9.5:1 CR, stock displacement, no intercooler (efficiency = 0%) - should give 347HP. Well, that'd satisfy me, at least so I'd tell my wife.

I wonder how long the motor would live. Maybe there's some way to have a bypass so that I'd only have boost when I wanted it, rather than subjecting the car to boost all the time.

I think I'm going to spend some time on the Protomotive board . . .
