"537/505 out of a truck rated at 350/380 crank from GM seems to work. yeah its no AWD, but since it dyno'd around 275 at the wheels stock..."


dyno sheet





Never knew the paxtons were that efficent, 1 psi boost = 23 rwhp

 

This on a Trailblazer SS? Stock CR? Seems like he is on borrowed time but I can see that gain with that much boost on a higher compression engine.

 

That is very nice and very well tuned.

 

a buddy of my had a 90 mustang with a paxton novi: the engine made 198 hp to the wheels, with 10psi boost it made 426 hp to the wheels!!

 

How are people either doubling, or in the last post, more than doubling their power levels with only 10-11 psi. I didn't think this was thermodynamically possible unless using something like an a2w intercooler to exceed 100% thermal efficiency. Cam swap also maybe?

 

You mean an LS2 trailblazer only dynos 275 at the wheels? Doesn't that sound low? I know I've seen SS trucks make over 300. With an LS2 and its larger cam, I'd assume they would make more than that.

 

Maybe they dynoed the baseline in colorado and the test in death valley.

 

wait, what truck are we talking about, and what else is done to it?

 

wondering what blower too...

 

This is on a Suburban. The owner post here under the username Y2KLimited.
