Quick backround, went to the track yesterday, waited for the rain to stop and finally got 4 runs in, temp was around 80 and it was humid. The DA was 2100, and we had about a 15 MPH headwind
First time out on my Bogarts, 16" ET Streets and the DFX. All runs except 1 were 12.0x's, I dont get it. The DFX was hittin hard, 60's were 1.67-1.75, and I ran some of my best 1/8 mile ET's and traps, 1/8 mile #'s were in the low 7.7's with traps at 94.xx MPH, that is a big 1/8 MPH for my car as my car has always trapped low. The car would just not pick up more than 20 MPH on the back end, I was trapping 114 MPH consistently, so another handful of 12.0's @ 114. I dont know whats up. If I picked up the normal 24-27 MPH from 1/8 to 1/4, I'd be well into the 11's
The tune is there, tuned by Hermann for 23* timing and I ran 1/4 tank of 93 and 2 gallon splash of unleaded 104, I have a tire and a clutch to hold it, and my 1/8 mile numbers should equate to an 11, but the car was still just falling over in 3rd and 4th. I was shifting it high ~6300ish and thats how I brought my 1/8 numbers up but maybe I need to shift 3-4 a little earlier, I have heard that this might help.
The only factors left are belt slip (74" Gatorback), plugs, and heat I guess, all 4 runs were done in about a 2 hour period so I'm sure the car was not cooled down all the way. The clutch was definitely not slipping. Maybe time for a H/E , and I already ordered the newer BF upper idler bracket and I'm going to try a Gates belt. Who has any other ideas?? I am speed shifting, not powershifting. I have a buddy with very similar mods and he got an 11 on the same day. How much ET is out there with powershifting?? Thanks for any ideas, cuz I am stumped!! Every mod is in sig, is something not jiving with my combo?? Could my MAF be pegged, could I be out of pumps? I wasnt out of either of these when I pullied in January, but have added a few mods, X pipe, Accufab TB, 10" powerstack on my FIPK heat shield, could those have pegged me? Thanks
