Adjustable front shocks to allow the front to lift for weight transfer, especially since you race with the zr1s. Then a dedicated drag tire setup with more sidewall. I dropped .5 sec and gained 3 mph switching from my replica zr1s to hoosier qtp's on 15" rims. It makes a huge difference in my launch, which looks very similar to yours.

An underdrive pulley would be your last big power gain for bolt ons

I have an underdrive pulley already just not listed. Yeah I'm not sure on what tire for the back. I have been lookin at slicks. I have the Weld Rts front runners. I have been looking at front shocks also just unsure what to get. I like the QA1s so maybe just a front set.

I run strange single adjustables and a 275 spring in the front. They can be cranked up for excellent street response, then adjusted when at the track. Obviously they worked great for my car, but I wish I went with a double adjustable.

I run the same 315 et street as you in street trim and Hoosier QTPs on my drag setup. The QTPs feel the same as the MT radials in terms of traction on the street, but holy **** do they hook at the track.

I compared my dyno graph to yours and its within 5 hp at every point. I think its weird you are only trapping 116 with such similar power. Whats your raceweight and DA usually like?

No idea, car has never really had high mph numbers. Race weight it about 3700 with driver, not sure on the DA.

Just an update found out that my throttle was only opening up 74%. It was causing shifting problems at the track. Still ran some good times and haven't been back yet after the fix. Got up to 119mph and down to 11.48.

Glad you are still finding/solving issues to get it where it should be....It would
not surprise me at all if your trans/converter combo is slipping or efficiency--
wise killing at least 5 mph of trap speed. The end justifies the means...
