I would like to know, from people who have the timeslips to prove it, who is running 12's all motor and on street tires. No slicks or "DOT" racing tires, no power adders, no track only mods. My car is a daily driver that has to get me to work, regardless of the weather. I would like to know your combination, and key parts/techniques you feel contribute most to your times. My ultimate goal is to run 12's in street trim.

To make a 3500 pound car run 12.99 you need to be getting at least 315 hp to the rear wheels. Since you don't want to run a slick, you're going to need more hp than that to compensate for tire spin since a street tire can easily break free and spin down the track.

The easiest way to make a car faster is to make it light. It takes less hp to run 12's in a 3200 pound car than it does in a 3500 pound car.

times in sig, mods in sig. Fully streetable, driven everyday it's nice, gets better mpg than a miata on the highway

sounds like your setup is close to mine except for the demon 750. I need to pass an emmissions test, so thats probably out. What kind of MPG are you getting?

zupmanZ28

i got through DE emissions with my demon. I actually did better with it than i did my old qjet thanks to a huge jet change.

My speedo and odometer don't work right now cause i put in a t56 and haven't decided what i wanna do about a speedometer, but for reference, i went to the dragstrip about 60 miles away and used just over an 1/8th of a tank at an avg speed of 80mph. Its a 16 gallon tank, so figure i used about 2.5 gallons, thats 24 mpg. Not bad considering i have 4.10's and a DP carb.

Now in the city....thats another story

does delaware have a dyno test or just idle emmissions?

fast86z28

my buddy ran 12.8@109 on street tires in his 84 ta...the motor is a 355, scat crank, h beam rods, lightweight forged pistons, canfield aluminum heads, huge cam dont remember the specs but its around .550 or so, victor jr intake and 750 double pumper, going through a super t10 4spd and 3.73 gears, he drives the car everyday, temp never goes over 190

well.....I'm almost there, times in sig. unknown horsepower.

zupmanZ28

DE tests emissions at idle, and then at 2500 rpm. No rollers.

Two words that translate into 12 seconds. BIG BLOCK. There are guys running low 12's with daily driven big blocks all the time. that is definitly the easiest way to the 12's.

laiky

i would love a nice big block but unfortunatly i don't think i can sneek that one by the visual much less the dyno inspection that we have to pass in NYS. Maybe once i get past the 25 year mark and don't have to pass emmisions anymore.

laiky

Any body have performance numbers going from a ccc qjet to a holley of FI

I'm there....
Here are the timeslip and comments.

David 91RS/Z28

I went to the track back in December in full street trim. I drove 35miles to the track, clicked off some 12.3'x passes with a best of 114.8 mph. This was with a 2.0 60'. I was on Nitto's, but these are the only tires I run. Still have all the comforts of AC, heat, etc. and I don't use any ice on the intake. Looking to improve this as I'm working on the latest round of mods.

I run consistent 12.20's with a best ever 12.13@112. Very streetable. 26 mpg on the highway. Never checked the mpg in town.

laiky

what kind of tranny and gears are you running? What about ecm, is it production or aftermarket?

jeffsbluez

Built 700R4 with SLP coverter. The rear has 3.73 in it and I run a 28" tall tire. The computer is a 730 with an Ed Write program. I spent many hours on the dyno to get the program right. Thank *** I have a friend with a dyno

paul_huryk

I don't know if it would be the easiest, considering the mods needed to drop a big block into a 3rd Gen. Besides, if you have a streetable 350 that runs low 12's, a streetable 454 should be able to run low 11's easy.

85TPI400

I better be in the 12s with all the money I just spent on all kinds new goodies. Ill find out when I get it back together!
Do you guys think so?

Major mods:
400 SB approx 9.5 comp.
w/ Edelbrock 6085 heads
Superram intake & base
Comp Cam 222 in.- 226 ex. @.050 .496 lift w1.6 RRs
SLP 1 3/4 headers

Tons of minor mods!

WC T-5 (until T56 conv.)

3.23 Gears

Any guesses on my times/ HP

Well I, like David, run around on drag radials, so if those don't count then I'm out.
Otherwise, count me in as well. 12.8-12.9 @ 106'ish mph in street trim. Drive it out to the track, run some 12s, drive it home.
Very streetable, sits in traffic for 45 mins. with no probs, could get 21-22 mpg if I really tried.
For my race weight I'm doing ok, not good enough though!
Timeslip is on my website.
