Hey guys, my name is Carl and I've been racing in the Houston area since around 2000 or so. I've been through several different combos over the years and ran everything from T&T, grudge, Indexes, and heads up in Ultra Street. I've spent the past two years trying to get my car competitive with those Ultra Street guys and finally decided I'm done with that heads up biggest pocket book is the winner racing. I'm going to switch to just running 5.80 index stuff locally and probably a no prep race here and there when we have them. That said, I've always run either pump gas on the old EFI combo, or race gas with the newer high compression stuff. Never tried E-85 although I have a few buddies that do run it.
The combos I've been through, first my 90GT:
started out with the stock motor with a little nitrous, blew a head gasket and installed TFS heads, then hurt that motor. I want to say 12.70s on a 100 shot.
Switched to a 347ci setup with the same TFS heads, Lunati 51012 cam (hydraulic roller 544/560 232/242), tried 3 different intakes (Performer 5.0, Victor 5.0, and Holley Systemax II). Went fastest with the Holley and 10:1 compression. 1.53 sixty, 7.05@98 1/8, 11.15@119 1/4 on motor and 10.70@121 on 75 shot.
Sold the EFI 347 and switched to a Carbed 408 with Canfield 192 heads and ported Victor Jr intake, 950 carb, solid roller Comp XE292r. Went 10.50@127 on motor. Spun a rod bearing after a year and switched to a 427ci shortblock at 11:1 compression. 10.30@130 on motor at 3000 lbs and pump gas. Switched to AFR 225 heads, still went 10.30 but picked up to 132 mph all motor.
Wrecked the 90GT back in 2008 on the top end of the track on a 10.60@127 pass (had weight in it and detuned for a 10.60 index). Picked up my current 80 Coupe race car and switched my drivetrain and some suspension into it. Ran the same numbers n/a with the coupe at the same race weight.
Sold the 427 shortblock and built a Dart blocked 434ci setup at 13.5:1 compression. Switched to a Super Victor intake with a 1050 dominator. Raced on 114 race fuel, 1.34 sixty foot, 6.05@113 1/8 mile, 9.57@139 1/4 mile all motor at 2950 lbs. 1.27 sixty, 5.67@122 1/8 mile on a .082 nitrous jet in the plate.
Threw a rod in the above motor in Nov of 2012 and parted it out. PIcked up a 9.2" deck SBF 12:1 compression 417ci setup with Yates C3 heads, 2863 intake with the same 1050 dominator built by Dan Davinci. This was a motor built for nitrous and has spent the last two years making nothing but nitrous passes. I think I only made one motor hit the first time I took it out and ran a 6.20@113 on motor at 3000 lbs. The best nitrous pass to date is a 1.26 sixty foot, 5.46@128 1/8 mile, no 1/4 mile hits on this motor. The motor came out of the old LX Law car from Fun Ford days in the late 90s early 00. it went an 8 flat 1/4 mile in Outlaw trim back then. So I figured it would work well for Ultra Street on drag radials. Just couldn't quite get it in the range that it should have been running (my guess is it should go 5.teens).
So after two years racing for 2nd place/runner up dollars and being the slowest car in a field of 5.0x cars, I've decided to step back to some budget racing and start running in the local 5.80 index stuff. I figure the car should get there on a little 100 shot on the progressive controller and back on some 28x10.5 stiffwall slicks.
So talk to me about the conversion to E-85. My fuel system consists of an 8 gallon plastic cell in the tank, -10 fitting/line from tank to a Magnafuel Prostar 500gph pump, then -8 line to a small inline filter and to the Magnafuel regulator just behind the passenger strut tower. -6 lines feeding the carb from the regulator. The lines are probably 9 years old or more. I have a separate 1 gallon fuel cell and Holley Blue pump with -6 lines to feed the nitrous system, so I was planning to just leave that alone and continue to use a race fuel on the nitrous side to keep things easy/simple (not have to retune the nitrous).
So based on my existing fuel system, what are your thoughts? Is -8 line enough or should I go ahead and make the switch to -10 line that is Teflon coated?
Since I'm always on the nitrous I run an NGK -10 plug, will this be OK to stick with?
Any tuning problems with E-85 on motor and race fuel going through the nitrous system on a plate kit?
Stripes gas stations have been the most prominent in my area that I've noticed having E-85 at the pump, anyone care to comment on their fuels and consistence? What kind of test kit should I get and what do you look for with regards to the testing and how do you adapt it to what you need?
I think that is all the questions for now, feel free to give comments/suggestions.
