Just wanting to know if there is anybody done this and were you stand. My car went 110.44 with a miss at 4900 rpm. my mods are ta49,009 injectors big neck intercooler 218 218 cam stock heads stock torque converter 340 fuel pump and adj fuel reg 87 ecm and jumper valve.
 
I ran 12.65 @108.5 with the tran slipping and a crack in the header, no scan tool. This was with the sperco intercooler and stock intake and heads and headers. Ta33 , 307 pump 206 cam and some others.
 
Cool. this car is really flying. just need to locate this miss fire ,we have linked to to this since my maf numbers fall from 255 to 225 above 4800 rpm.this was at 21 psi. we are looking to run 24 psi we it all said and done.
 
What was the time that it ran , and was it with a street chip or race chip. Fix that mis and you should fly.
 
It was with 108 octane and a chip with timing at 22. that pass was a 12.71 with a 1.90 60 foot slicks are wearing out fast. Since we are guessing on fuel now since the maf is maxed out we been adding 4 percent more fuel this is chip number 3. o2 volts 770 to 800 that run but it will need more when we add more boost. On this run I ran a all out race car with a 440 big slicks the hole nine yards. another 1/32 of a mile he would of been seeing them buick tail lights. we looking to go 12.0 on this combo and I think it will do it.
 
I've been 12.3 @ 109 with a te44, 40# injectors, IC and a half, Walbro 340, red stripe TC, ATR 3"dp and single shot exhaust, JC strip chip, BFG 275x50x15 DRs on GN steel rims. Motor has never been opened and this was with 22-23#'s FP. Car had a best of 12.0 @ 110 with skinnies and slicks on Weld draglites a few years ago, missing at the top end.
 
It has weld lights with skinnes. I was shiffting at 5100 so this miss was only for 300 rpm. leaving at 6 pounds of boost . this is a car that went 15.40 stock in hot air form. havent backed it up yet but that should be no problem since the pass before was a 12.89 at 109.97 and then I added two pounds of fuel pressure then it went 12.71 at 110.44. this is with the converter locked. what a releif now that things are under control. all the credit goes to our local chip burner. great job.
 
I went 12.9@ 110.3mph with the Spearco setup. TA49, ported intake, headers, and 2.5" DP. This was pump gas, no alky, 18psi for almost the 1/8 and then falling to ~13psi for the rest of the run due to a plugged convertor. I feel this combo had an easy 11 sec pass in with race gas, race chip, slicks, and more boost.
 
I've done 12.80's with out an intercooler and hope to do 11's here shortly also without an intercooler and before adding the alcohol.
 
The valve springs should be ok, this happen when I changed a few parts at the same time. it used to go to 5800 but I sold some parts off of it like the ecm typeII ing set up and then put the turbo, injectors, different ecm and ing set up now wont rev. should have it sorted out this weekend.
