GPI L99 Whipple w/ VVT Custom Grind *DYNO PG 2*

Results are in!

I installed a whipple with a 4" pulley, MSD Boost a pump, Zl1 pump, Custom Grind VVT, (already had LTs and CAI intake). Car drives good with stock converter, Idles at 700 rpm, and made great power despite the heat today!

611.7 rwhp and 527 rwtq on stock heads and stock bottom end, unlocked stock converter.

It made 6.8 lbs at 3000 rpm and at 6700 it was about 8.1 lbs.

Super flat tq curve and HP just climbs and climbs, and was still climbing at 6700 or so.

The cam works great in conjunction with the Brian Tooley springs. Valvetrain is super quiet and car makes great power everywhere.

The owner is a member here, I didn't get a pic of the graph before they left but Ill post it up when I get to the shop in the morning. Here is an idle clip though.

Are you going to install another cam for comparison?

What cam do you have in mind? Compare it to which one?

A non vvt. No specific numbers in mind. That's your department. That shits Greek to me!!


I thought the plan was to show a blower vvt set up vs an ls3 conversion cam. Actually, someone prob already has a whip with an LS3 conversion cam.

Not on this one, Id like to do a comparison on one that already has a ls3 style cam. This car was on a deadline. I ran the cam at various spots during tuning, to determine where to set the cam timing at for each rpm point, and it made a nice difference in power from 5000 rpms and up vs leaving it at full advance (installed centerline).

Cam is small, and at peak tq its only at 7 lbs with the 4" pulley. Also take into account I don't lock the converters on the dyno unless its a triple disk.

With the stock cam, on my TVS, I made 550 rwtq with 2 more psi? Is the extra boost worth that much?

About 20 hp per lb.

TVS cars typically have higher tq than the whipple, with the whipple being a 2.9 vs a 2.3 and only spinning enough for 7-8 lbs, its not as efficient as the Maggie at lower speeds. It needs another 2lbs on this car and we would see 560 tq easy and around 640 rwhp easy.
