VVT1 or VVT2 - Help me choose It's time to buy a cam for my 09' 6.2 L92. The plan is to swap the cam, add long tubes and a tune for max power and good driveability. The motor is a VVT engine without DOD. I am considering either the Texas Speed VVT1 or VVT2 but finding apples to apples dyno comparisons is difficult.
The engine is going in my 3600 lb 1986 Olds 442. It has a beefed up suspension and frame with the 3.73", 8.5" rear and will get a 4L80E trans and I'm willing to buy a small stall if needed. I hope to break into the 11's with this car. Any thoughts or recommendations for those that have TSP VVT cams?
Thanks

The argument I always have to the let someone custom grind you a camshaft is this:
If you could use a lobe catalog & nail every cam combo why would companies spend 100k+ to build dyno cells? Why not just buy the latest lobe catalog & roll out some lobe numbers?
With the TSP profiles I just about wore out a L99 engine making countless dyno pulls testing everything you could imagine. With weeks & weeks of nothing but swapping camshaft profiles into the L99 engine I'm 1000% confident the TSP camshaft will outperform a custom grind in most applications.
Patrick does a great job & I like him a lot, he will always do a great job lining you out a camshaft no doubt.
What we offer is simple. We spent the tons of money & R&D time to make sure we offer the best combinations for our customers. Nobody else in the LS industry has spent 200 dyno pulls testing L99 camshafts side by side. Nobody...
That's why when you call & say what does this cam do vs this cam side by side we can tell you. You don't have to hear Bobs SS made 425 & Larry's SS made 430 so cam 2 must be 5 better. We all know side by side is the only way you actually know which cam is better at each rpm!

Thanks for your input Jason,
Can you provide an Dyno curve that would represent my combination and your VVT1 camshaft? The L92 will be stock other than long tube headers, and an ECM tune. What is peak horsepower likely to be?
Thank you

Haven't seen any other shops make and perform like what they do.
Ryan spends nights and days on VVT profiles. No one has gotten close what he has done

Sorry about the delay. We have been so covered up with phones lately, we have not had much chance to log onto the forums. PM me your e-mail address and I will try and send you the dyno graph you're looking for today.

I still say Patrick G
After considering the options, I have chosen to take the vvt out for a new cam. The first thing I noticed when I pulled off the vvt was the WEIGHT of the phaser. It must weigh 4 lbs. The new cam gear weight less than a pound. That should be an improvement.
Thanks
Yeah, I have seen that also. Not wanting to call them out, but I find it hard to believe that they spent all of this time researching these cams, then can't seem to find any results.
