dyno time for my whipple denali
#11
I am not 100% positive but from what I understood is the kit from whipple used the stock injectors. I was told when it was tune that I was close to maxing out the injectors and I would have to install larger ones when I stared to increase the boost.

From what ive seen those 6l80 transmissions are good at taking power they just have to be tuned right.. Im running 550-600rwhp on a stock 6l80 and its doing well, ive seen camaros and cts-v's running close to 700rwhp with a stock 6l80 as well.. 425 is awesome with 5.5 psi.. Any plans of adding more boost? Its addicti g

I would go with RPM transmissions for you build. I had gearstar build me a level 4 4l85 transmission which should have been plenty for my setup considering I was only making around 450 rwhp in my Whipple Denali setup only for it to blow up and they wouldn't stand behind it.

They don't offer a 6l80e for the trucks. If its the same company, then they probably use PATC, who do make a nice 6l80 but to the tune of $6,900. The Gearstar 6l80e upgrade actually has more upgraded parts with the exception of the powerglide 4-5-6 clutch packs that PATC uses. Also, Gearstar is only an hour from me. It's kind of a risk whoever I use. Plus, I don't like the idea of a new TCM. Gearstar will take my tranny, upgrade it and upload an optimized TCM tune.

The 8# claim is based on 5.3L. All of the 6.2L trucks with Whipples using the 3.625" pulley on this site have been right around 5.5-6#.
