ive actually been three times this year since gateway reopened. First two times where a couple months ago, and it ran a consistent 13.8-13.9 @101-102 with 60's in the 2.1-2.2's (yes, i suck at driving, but still seems a touch slow). The second time i went a heater hose decided to burst on the second pass, forcing me to limp it a mile or so to get a new one. Ended up putting new head gaskets and a timing set gasket on it to cure leaks that popped up, and issues with an ect and a dead battery, but its been driving fine down the road now for two weeks. Also switched my pos mac cai to the stock airbox setup because one of the couplers decided to rip in two (that and the fit was horrible).
Then i went to the track again on weds. Got 6 passes in, missed third twice (oops, like i said i suck at driving). The real problem is the other 4. Could not get the car out of the 14.4@98 range, even with a (single) 2.0 60'. I could even feel the sotp power loss, especially on the 1-2 shift. And it was like this on EVERY pass, even playing with launch rpm and shift points a bit (3500rpm launch and a 6200rpm shift on the stock tack seemed to work best)
Im just not understanding how it lost (gained?) a 1/2 second and 2mph, though to be honest the 2mph worries me more than the 1/2 second (remember how i suck at driving?). Im hoping its just a tuning issue more than anything else.
Been tinkering with it today, pulled all the plugs and they look a little white/gray, and while i was there hooked up the compression tester and got 130-145psi on all 8. Timings at 14 initial. Whole combo is:
Explorer gt-40p long-block
tfs stage1 with the tfs spring kit
stock explorer rockers/pushrods/lifters
shorty headers
tfs street intake
24# injectors
c&l maf for the 24's(yeah, i know, not the best)
fpr set at 38 psi with vac off
stock suspension other than b-springs and tockio blues
