I attended a private rental with a group of guys last week in London Ky. I had the car on 50/50 race gas with my street tune with additional timing added. The car is short shifting due to running out of fuel up top with the stock pump (using a BAP).

The car has a Boss short block, Boss intake, Kooks long tubes and x pipe, stock axle back with GT500 mufflers, Vortech V3si using Beefcakes waste gate limited to 12 lbs.
I am running an auto with a Circle D 3c and 3:31 gears. I have quite a bit of suspension mods done that lets it 60' very well.

My best run is below in the right lane. The DA was 800' on this run.

Awesome run! Have you been running the Boss shortblock this whole time? Also what supercharger and pulley setup are you running?

Yes, I ran the boss short block for 4 years and just pulled it out. I am running a Novi 2200 HD oil fed head unit with a 3.48 pulley in the video above. At 7500 it is around 17 psi. I run a Boss intake also.

I noticed the motor was using a little antifreeze every time I raced, when it was pulled found a small crack in the #3 cylinder. The car ran fine however, The last pass was a 9.26 at 149... then drove it 60 minutes home. That motor was unbelievably strong. It had a little over 5000 street miles and well over 600 passes.

This combo dyno'd at 856 rwp on a Mustang dyno at 6700 rpms..... but we rev'd it to 7500. So my guess is around 900 rwp. The Boss internals are strong for sure.
