Bottle Pressure?

Well i went to the track Sunday and ran a 11.14 at 123mph with my bottle pressure at 875 and i was wondering if i would see any gains if it was up higher about 1150?

Depends on which kit your running, and the rec pressure to run at. But yes, more pressure will equal leaner and more power. watch your a/f so you don't go to lean.

Tnt specs their kits for a 900psi bottle pressure, so 875psi was pretty close. As long as your a/f was fine, rasing it any higher will lean ya out some.

Raymond,im running the same kit and had similar questions. I spoke to tnt about it. They said they dont sell a 175hp jet set because by simply raising you bottle pressure to 1100psi would be a 175 shot. I actually took it to the dyno and i was at 170hp gain with the 150 jets. Dont have my dyno sheet handy, this was a while back but all a/f was totally safe and i have more than 40 runs at that psi with no issues. Tnt is a great kit, call them they helped me out alot.

I think that is a great a/f, raising the pressure up will lean things out, depends on far you want to go and what hp level.

Exactly what I was talking about. What did your a/f become after raising the pressure? what was it before? This will add some insight. Tnt is known for good torque out of the box, this is achieved by being a tad rich normally, so seems there may be some room to play with by increasing pressure and going leaner but not to the point of issues.
