Now, there are Mustangs that now go 12-1 and can run on CA 91 piss gas. That is kind of impressive.
I ran 12.25 with those out dated E-heads. Soffen chambers for running nitrous,
One of key things for running pump gas is cam design. Itís design to bleed off compression. Carb tunning is also key ! Which is Just one part of it. Donít care what pondents think, like I said 93 octane right out of the pump 30 dyno pulls and 16 passes at the track. No denotion was so ever.
New combo only 11.1 much more tuner friendly for my son. Another thing the 93 octane around here has 10% ethanol which also helps. Yep the new LS 6 fast burn chamber helps. But itís not the be all end all clincher.
Besides I could give a F.U.C.K less whether anyone believes itís possible or not. Iím not trying to impress anyone. People ask how and I just tell them what we are doing so far having success.
The things they hide, the way they spin things, the excuses that they make and the things they omit.
