Finally got some dyno numbers, lower than I expected but I'm only running one tune for boost/nitrous so its a conservative tune. My boss thinks my no name port and only making 13lbs of boost is holding me back, which i can see, but i'm not worried about it. Boost only it made 458/472 and on a .038 jet(around 55 shot from what I can find) it made 530/571. That said, what should I run at the track now, figure it made right around the same numbers on the mail order (right around 450-460), so my original goal of 10's on boost only might be a stretch. Still hoping for mid 10's on the juice tho, you guys think that's possible?

038 should be closer to a 75 I think..my 75 says 040 and my 50 says 022. Either way, no matter what the dyno read today your Cobra has still gone 11.4 and trapped 124 mph. So everything you do from that point on including the new tune will only help. Even on the 50 shot you should run a high 10 at worst and maybe a mod 10 with all that extra TQ. Have you tried spraying on the street yet?

it only trapped 123 . lol. I'm hoping for a 10.5x @ 130 depending how good the track hooks and air temp is on thursday. I haven't sprayed it on the street yet. To be honest when it activated on the dyno I couldn't even feel it, guess that's what happens when you activate it high at 4k rpm. I'm gonna have to lower that some lol.

I don't know what suspension you have but 460 should get you pretty close to 10s. On the spray I thing it should go mid 10s. I'd set your window for 3-6K for the spray.

I wouldn't worry about the numbers greddy! Your car runs strong for what it is and we both know it
