The build part is finally finished. Testing on the dyno started Friday, first full pull @7,000rpm with 26 degrees of timing:
1120 RWHP Est. 1400 at crank - 22.6 lbs. boost - 66 degrees inlet air temp
We will do the final tuning at the track + add more timing to about 34 degrees. After that is done I will take it back to get a final dyno HP number.

I am using Holley dominator with Holley digital dash.
I would put a procharger F-3-136 on if I wanted to go faster.At the end of the 1/4 mile @ 180 mph the marauder is not that stable when the slicks come down .

Have you ever considered putting a radial on it? Like the 315/60-15 Mickey Thompson ET pro?

I have considered it but I will stay with the 32/16/15 slicks. they have given me a 1.22 60ft.

I couldn't imagine a 1.2. My converter is out getting restalled, I'm just hoping to get back into the 1.50s, maybe 1.40s. It's footbrake, I don't wanna put a brake on it (yet).
That ET pro, Keith Haney has gone .98X to the 60' with that tire. Not an apples to apples comparison I know, but the tire can get the job done if you adjust your program, which you seem to have no problem adapting.

The ET pro is a great tire.My friend uses it in the NMRA renegade class and has run 7.40 @ 187. The Purple car has a 1.34- 60' on footbrake with a 31x13x15 slick.
