Another Va Speed mild combo

For a retired gentleman that drives, well, like he's retired LOL.

06 Vette, LS2 (obviously). When it came in it had quite a bit of spark knock in it. That's why the before numbers are so low.

We did an induction service to it. Then we added 1 7/8s headers, catted X-pipe, custom cam (pretty mild), pushrods, springs, underdrive pulley, Halltech CAI.

The car has a bit of lope to it when warm, but not much really.

Gotta love the gain in the low end. She pulls hard from just off idle.

Great numbers, that's for sure.

Probably just a build up of carbon from just puttin around. The induction service got most of that out. We would have picked up a good bit of power with just the induction service and a tune.

Why the larger primary pipe on such a mild combo?

I would have been inclined to go with a 1.75 pipe for better part throttle scavenging and improved SOTP

Nice WOT numbers no doubt....

I've never seen a significant reduction in low end torque from using 1 7/8s over 1 3/4s. EVER......

Matter of fact I've swapped a couple sets of 1 3/4s out for 1 7/8s and saw zero loss.
