This is with a 3600 stall through a built A4 with stock 10 bolt and 3.73 gears, 17" MT ET streets @ 19 PSI on Heavy *** WS6 rims. Single cutout, and only 24* of timing. Judge for yourself. Please keep in mind I have just about every bolton and supporting mods imaginable. FWIW, I'm now running true duals and 28* of timing, and it pulls harder then it did when the graph was made. I haven't had a chance to have the car re-dynoed yet with the new changes. Oh yeah...It REALLY likes N2o. Have fun.

a buddie of mine has pp 5.3's and the g5x3 and only made 420 rwhp. that was with a m6 and 10 bolt w/ 4.10's. the best times he has ran at the track is an 7.87 @ 94 mph (1/8). i was going to get this cam until he got his. the car pulls like crazy up top but not enough down low for me. my car pulls away from him all the way until the begining of 4th gear.

Well I intend on stepping up to a 383 this winter and I will be staying with my X3. I was just going to get forged pistons and rods, but for the price difference I'm going to go ahead and get the Eagle 383 package. It's only like $2000. I'm not too sure how much the extra 40 cubes is going to help, but I figured that I'm getting 1.3 rwhp per cube now, if I can step up 40 cubes, I should be able to get real damn close to 500rwhp, which is my goal. I'll also be sending the heads back in to Patriot for some updating to the new Stage III. I've actually got the old springs in mine so they will be doing new springs bigger valves and new port design, along with seals and all that good stuff. I 'll think I'm going to have them take the compression down about a point to 10.3 or so. I intend on going to a moderate (7psi) turbo next year, and getting rid of the nitrous. I want the power all the time. Hell who knows I might keep the nitrous too.
