2010 Camaro TVS Cam suggestions
2010 Camaro TVS Cam suggestions We have a 2010 Camaro L99 (auto) running TVS 1900 currenlty 5psi with current cam (will be 7-8psi with new pulley), ARH headers (cutouts will be added soon). The current cam is a N/A style cam designed around the VVT of the L99, in an effort to make more power, we are contemplating using a non-VVT cam designed specifically for the TVS.
My only stipulation is this...right now my cam is mid 22x/high 23x ~115 LSA, I like the sound of it, it hits pretty hard...I'd rather not lose that "sound" if possible. I know I might sacrifice "some" power like this, but I'd like to find a nice compromise between the old fashioned cam sound and forced induction power production.
The goal for this project is at least 520rwhp thru the auto, and at least 122mph trap @ +2000DA.

LMR has a car that has a TVS, blower specific cam headers and CAI and on 5psi it made 570+rwhp...they said on 7psi it was easy 600rwhp thru the manual tranny. That would equate to a little over 700 fly wheel hp...If you figure my motor with similar cam and boost would make 700 fly wheel, figuring 80-82% drivetrain loss, it should be around 560-580rwhp with blower cam and 7-8psi...If I get 7psi on my current set up I might be at 500rwhp...
So that is why the cam is so important. HPtuners appears to be a little behind on the VVT tuning ability, and my cam is VVT specific, so we are debating deleting the VVT components and just running a straight blower cam...we've seen from other shops what regular cams + TVS's are making...and with a blower boosting low end TQ the VVT is not really that big of a deal for a FI application.
I'm holding 5psi now and i'm at 470...don't think i'm picking up 80 rwhp from 2psi...something else is wrong. The VVT cam needs to go. Need a blower specific cam that doesn't utilize VVT...no one, including the cam grinder knows how to make this VVT work with a blower.

Yes, the VVT cam needs to go. A mild blower cam and 7psi will get you well past your goals. 2300 TVS on my LS3 vette with blower cam and bolt ons made 672 at 8+ psi. The cam wasn't even as big as the one you're considering. High teens on the intake, lots more on the exhaust, healthy lift, and 115LSA.

I saw your thread when I searched TVS...Awesome power man, congrats, I settle for way less than what you made.
With a performance exhaust, there's no mistaking mine for stock. With a bigger cam, you might kill a little of the low end power that the TVS can make. Drivability won't be quite as good either. If those two issues don't bother you, go for it! It won't "hurt" power wise. It will probably just move the power band up a little. Might get you a few more ponies on the top end too. You might check with Allen at Nelson Performance. He can help you on cam choice.
Does the LS9 or LSA have the same cam design as your Camaro? If the cams interchange, that gives your two pretty good blower-specific options... unless the LS9 and LSA are VVT engines.
