Right now i am running 12.93 @ 104.5 with 1.73 60 foot. Almost full bolt on 94 LT1. Long tubes 3600 stall mt drag radials

I want to get to 12.50 or better.

I have an idea of what i want to do and what i think it will run after each please give me your imput if this sounds realistic or not.


1st, cut out, wideband, and some fueling adjustments to net -----> 12.89 or better
2nd, 100lbs or more of weight reduction and drag shocks --------->12.83 or better
3rd, Lightweight drag wheels out back and skinnys up front ------->12.70 or better
4th, 1.6 or 1.7 roller rockers and new springs and pushrods ------->12.60 or better
5th, E85 and full dyno tune ------------------------------------->12.50

also at some point probally when one of my above steps doesnt net the time i am expecting i will add in a home made ram air

does all of this sound possible? Please tell me if i should expect better or worse Thanks in advance.

The drag wheels, 1.6rr, and 100lb weight reduce should have you close. I would just do a mial order tune for a bolt-on car. I ran 12.3s with full bolts-ons besides ewp. I had a 3800 stall tho. What gears do you have. Also how are you leaving the line. off idle or foot breaking

I gained 2 full tenths by removing my a/c,front sway and skinnies. it was 47lbs off the nose + tire weight..

I wouldn't recommend removing your front wheels for weight reduction.

mods so far.
svo 30's 255walbro msd opti plugs wires and (delteq with msd dis4 ign box and msd two tower coils)--->delteq setup possibly for sale soon works perfect
smooth inlet elbow, 3.73 gears, 3600 stall, long tube headers, old crappy mail order tune adjusted by myself with tunercat, k&n cold air, elec water pump, aluminum driveshaft, an airfoil, 100% stock throttle body and engine internals stock valve springs and rockers, still have full ac abs and powersteering, no egr or airpump or sparetire. Fiberglass hood. LS1 trans am 5 spoke wheels painted black with mickey DRs no front sway bar, battery in spare tire well

I cant think of anything else of importance

i foot brake it till about 1200rpms then hammer it on the second to last light how do you do it?

bout the same way. Why did you go to 30 lb injectors? The 24's were more than enough. If you havent had it retuned since you added them then your rich as hell.
Pull your a/c and front sway bar.

yes of course it was tuned for thoose 30lb injectors.. i was going to do a h/c/i package but never got around to it, now im hoping i can do e85 and the 30lbs will be large enough for it. Front sway bar is off and i like the AC

just remember e85 requires about 25-30% more fuel so more pump and injector and hardest thing for me was finding stations within 3 counties i have 1 station on the turnpike that carries e85

i have a walbro 255lph pump and With these 30lb injectors i my max duty cycle is around 60% so i figured if i need 30% more fuel then if you multiply my 60% duty by 1.3 that would put me at about 80% duty cylce, does that sound about right? i have a station less than a mile from my house and also there a station about 10 miles from the dragstrip that i go to so i should be ok if i plan ahead

lol i was just making sure. weight reduction is always the cheapest mod... Good luck i think you will hit your goal. p.s. I wish i would have pulled more weight and ewp. It would have been nice to hit 11.s with bolt-ons. 10s on 150 shot.

what all did you do as far as weight reduction?

Walbro 255 don't work very well with E-85. Just a heads up, I seen a few guys have nothing but problems. So you will need to get e-85 compliant pump.

I pulled out rear seats, front sway bar, a/c, rear seat belts, spare tire, drag wheels, and my exhaust set up was light. Now i have kmember, no airbags, removed door bars, heater box, front and rear bumper supports, horns, and cruise control.
