Ported 241's and Cutout Results http://i166.photobucket.com/albums/u.../dynograph.jpg Red is with Cutout open Solid 6 whp and 7 wtq gain from the cutout I made 409 whp and 394 wtq before the ported 241's and cutout. Note that I also have a 12 bolt with 4.10's now as well. So if I factor in the loss from the 12 bolt I would guesstimate a 30 whp gain from the ported 241's. 2002 Trans Am 6-speed Advanced Induction ported 241 heads Custom Comp Cam Bolt-Ons 12 bolt w/ 4.10's |

damn, im gonna get some cutouts....it cant hurt. 7WHP is hard to argue with |
may be wrong but i have seen setup like that be near 450whp. or does a set of after market heads make that big of a diffrence?AFR,TF,etc. |
AI ftw!! They are doin big things with lt1's and ls1's :usa: |

Let me clarify a few things here... Bruce was a ding dong and went to the dyno without me ( :lol: ), so I wasn't able to dial the setup in. If I was present with him on the dyno I could've probably got the car in the 430-435rwhp and 400'ish TQ range. Which is a respectable # for Stage 1 241's, 12 bolt/4:10's, stock intake, and a rather small 228/232 cam. The heads have stock valves. We'll get some better #'s when Bruce and I can schedule a time to go together to the dyno for some adjustments. These are preliminary #'s. |
definately preliminary #'s. I'm still impressed the ported 241's gave me as much as they did though! |
Yep. Nice big fat TQ curve though. Thats what matters. |
Thats a pretty good gain from the stock heads |
Great numbers! Sweet combo and I love the Keep it Simple Stupid rule that you are using with maximizing those parts. Awesome man! Let Damian tune it. Post a video if you can. |
Nice. Graph has a steady pull to it. |
Nice numbers! Ai does great work!! |
My exhaust sucks so bad I gain 17hp from a open cutout. I have kook 1 7/8 w/custom build off road and the power killer is the b&b tryflow catback. The b&b sucks for power... |

I am always curious to see how much cutouts affect HP/TQ. Nice ride! |
