2011 GT500 Dyno with Headers

[venom55]

I wanted to share the surprised gains I got from just added 1 7/8 American racing Headers in place of the off road x pipe. This was done with the same street tune, same day, the same dyno at SPEED Inc. We expected to see little power gains with the work that is already done. Those headers must flow even better than the x pipe, lost 3lbs boost still.. 39 whp gain, 42 tq.

Finally some nice weather today:lmao: Anyone up for Route 66 tomm. and some cruising at night???

Sorry attachment of dyno to big???? PM your e-mail if you want see it.

Thanks,
Joe

WOW that X-pipe was restrictive as hell. Losing 3psi is a BIG gain in flow. Congrats :biggthump

lean is MEAN baby!!!













until it goes BOOM! Am I reading this right? That graph shows a lot of time above 12:1 AFR between 5-6K rpms. On a forged motor that might be OK but with a cast/boosted engine that's on the ragged edge.

 

[venom55]

The car keep breaking up in second under WOT... then some black smoke comes out.. not all the time.. thought it was a little too fat on fuel??? any suggestions

 

[Bob_Kurgan]

what plugs and what gap?

 

[venom55]

NKG TR6 plug 1 degree cooler, .030 gap.. Bob could i have you retune my car?? I have an SCT tuner, it was remote tuned by Jon Lund on a dynojet at SPEED inc. I also want a C116 tune for the track.. If you can please PM me.. Joe

the first thing i would do is get a new set of NGK BR7EF and gap em around .022-.024... this is a CHEAP and quick test.. if that solves it, i would contact lund and ask him to richen up your tune... if all else fails, send me an email and we can talk.

thanks and goodluck
