dajogejr Posted October 15, 2009 Report Posted October 15, 2009 He did...and here was my reply for other users as well. You'll have to fatten the pilot jets (to 55 or so), .120 on the dumps sounds about right. Probably start of with 3 sets of mains drilled. One set at .116, one at .118 and one at .120. The main can only flow as much as the dump tube is drilled. I honestly don't know what needle to run. Dan Hull @ A&S racing is the man with PJs on methanol. He grinds his own needles....he can probably tell you better than anyone out there. Also...when my buddy had his 34PJs done by Dan Hull, he also told him unless he had triple exhaust ports on his cylinders, he didn't need a power jet (an external adjustable jet that uses engine vaccuum to pull more fuel) While he is the man, for a little extra money I would rather have the insurance of Powerjets for more fuel.

JMADD Posted October 15, 2009 Report Posted October 15, 2009 Yeah,you can always turn the powerjets off if you don't need them. I'd definitely install them. Quote
tundish2800 Posted October 15, 2009 Report Posted October 15, 2009 Im running 34pjs with a 124 dump 118 main and a 58 pilot. With no power jets and it ran just fine. But i will put them in for next season. i only drag race though Quote
