without slicks lol. so now you cant bolt on slicks huh. wanna make another rule lets think about how you can limit the factors more, huh how about 2 plug wires have to be pulled , will that help your side out more? click on the link in my previous post. 137,000 mile lt1 bolt ons only 11.8 . theres your bolt on car running more than low 12's. you can say "oh e took weight out " , "he did this he did that" FACT is hes a bolt on car, NO CAM, no nitrous, no blower. hey dont cry casue he has slicks, he is getting it done with bolt on's only.

Settle down chief. I would believe he would know if his friends car had a full tubular suspension and half the car was hacked up. Not to mention the 3 gallon fuel cell that would have replaced the gas tank. We're not talking about someone who went hog wild, like some of the fast bolt on cars have done. From the way it sounds, and this is my interpretation, the car just has a FEW boltons and the kid claims low 12's. End of story. Myth busted.

By the sounds of it this guy your mentioning ain't no Shon Herron or any of the guys who have made some REAL progress making some good #'s with bolt-ons.

Your typical LT1 will need a cam to get into the low 12's.. by typical I mean full weight street car w/o radical gearing or converter.

I went low 12's and as fast as 12.0 @ 112.81 with a 1.66 60' time with just a cc503, 2800 stall, nitto's, and bolt ons... car would have gone 11's but I bent a pushrod and hurt stuff, so that quest ended.

Re: what does it take to run a 12.2 in the 1/4

I know we're talking F-bodies here, but my buddy ran a 12.50 in his 94 LT1 Vette. MT Dr's, longtubes, 52mm TB, LT1 Edit, CAI... and I think that's it... definitely no head, cam or gear upgrades. He races in national SCCA events and has been to many driving schools. He's probably one of the best drivers and drag racers I've seen. Unless this guy has some serious weight reduction, I highly doubt he's seen a 12.2 with those basic bolt-ons.

Has he owned the car since it was new? Maybe it has a cam (and/or other internal mods) and he doesn't know about it.

Re: what does it take to run a 12.2 in the 1/4

Off the shelf, out of the box, full weight 97 TA at Englishtown Raceway park; 14.2's - 14.4's through the summer.
Gear change from 2:73's to 3:42s', DR's; 13.7s
Headers, cat back, mail order tune; 13'3s

But what's the point if your're bracket racing...

Cam and 1.6rr's this weekend...

This is what I got when I questioned the advertised 13.53 stock times of a 1993 Firehawk.

The F-bodies are all over the board with times, I remember in '97 we tested a bone stock SS 6spd car and the average time we pulled was somewhere in the 13.38's. Scott Kallita (top fuel driver) got in the car and then ripped out a 12.27 and he backed it up with a 12.29! (we didn't advertise that time). In 1999, I drove a bone stock Formula Firehawk six speed at Napierville Dragway outside of Montreal. Out of the box I ran 13.30's and then with my slicks I ran a 13.05.


Sea Level, Barometric Pressure, Track Conditions, Driver capabilities and the car all play a part in your ET's. Just because you may be in Denver at Bandimere Speedway and you run a 14.40 doesn't mean your car is slow. Adjust the ET based on your altitude and you may be surprized!

Even if he had slicks I guess the 'bolt ons' included a new rear end. Hard launches with slicks on a weak *** 10 bolt spells out gear oil all over the track.

cheif lol thats cute havent heard that since i was a kid. i didnt say his friend could run low 12's with his unknown setup, only made the point it can be done. if you meet a kid thats tells the truth about how his car runs , when he isnt stading at the track, i'll give you the keys to my old 79 z28 project car. thats not a myth thats called a lie by the way, by that kid. my only point is it has been done and is currently bring improved on by the same folks.

Na, it's cool. I completely understand where you're coming from. It just seemed that you were getting a little upset. The myth part was something that I thought sounded cool and would finish the post nicely.

Bottom line, it's difficult to do and I would call .

i would call a 12 bolt a bolt on, in a split second. hell a 12 bolt will take more power to turn. guess you guys think of bolt on as cheapass mods that dont do to much to help , like air foils lol. when can you call something on a car not a bolt on? i would like to see the list of qualities that makes or breaks a product from being called a bolt on. when you see a new set of heads they nornally say "100 bolt on horsepower" so where is the line drawn?
