Gen 3 2.9 Whipple

[GT500_012308]

Knew a guy and with same setup as his gen 2 pulley etc made like 35whp more but he noticed lower temps because blower isn’t being taxed to make the power........he is gonna throw a smaller pulley and lower tho so interested to see what it makes

Results are in on my 07 GT500, 748whp and 729tq @19lbs of boost and 770whp and 768tq @ 21lbs of boost. Car has Innovators west 15% lower and 3.25"(19lbs)/3.0"(21lbs) upper pulleys Was at the edge of the stock maf @ 21lbs so will be running the 3.25 upper with 19lbs for the time being.

How does the torque feel? Is it improved to TVS style low end torque or is the power more top end of the RPM band?

Curious about the low end as well. What blower did you have before?

That on E85?

Yes this is on e85 and about 19.5 for the timing i believe. I had a stock Stegi ported blower before @15lbs with longtubes making a touch over 600. The short time i have behind the wheel of this now, i say it still pulls very hard down low but the top end it crazy.

Cool man. Those are great numbers for sure.

Wow, 1.5 psi increase and you gained 20 hp and a monster 39 torque? That's pretty impressive!

Any idea on blower discharge temps?

 

[whitesnake86]

Thanks! Very happy with the numbers. As far as discharge temperature I'm not sure.

Very nice and I’m jealous. My car is just rotting away in the garage with very seldom spirited cruises.

I haven’t modded in years and won’t be happening anytime soon.

But I do have 3 beautiful new baby girls!

Nice numbers! The Gen 3 2.9L Whipple is very efficient. I saw similar gains over my Gen 2 same pulleys. ~ 40rwhp/40rwtq peak but gains are across the entire useable rpm range. I see ~ 19psi w 3.0 UP and 15% IW lower on my 5.8L 2013. Tune is 17 degrees max timing on 93 oct making ~ 780rwhp/750rwtq. May do a mono blade and E85 tune next just afraid to push the stock rods well over 800rwhp.

I'm thinking about changing to a mono blade as well but not sure if I should push it anymore as well. Just gotta drive it as is and enjoy it for now
