I'd like to see how quick I can go with my bolt-on camaro on street tires. My car is a full weight SS (3700 lbs) and recently ran a 12.27 on street tires. I know my car makes a bit less power than others I've seen on this site with similar mods. Because I ran my best time on severely weak valve springs, I'm wondering how much power I may have picked up with the new springs.

I was short shifting at 5500 rpms with the valves floating in 4th gear around a couple hundred feet before the finish line.

I may try some skinnies to reduce a little weight but really don't want to try anything else.

What do you guys think? How quick do you think I can go with this setup?

What mph would I need to see to run an 11.9999/

It depends on several things, my SS ran 11.35 @130 on the every day 295/35/18" Kumhos. I had enough power to make it up on the top end though.

With the power you're making, I'm sure you could probably launch in 2nd gear to an 11 second pass. With the power I'm making, it will be a bit more difficult.

Running fast on non-drag radials takes a delicate balance of clutch and gas. Based on your 1.86 60 foot time, there's more left but some street tires are a harder compound than others and that won't help much in your quest for 11s.

I've gone a 1.71 60 foot on std 275/60/15 radials in my Nova but with a good loose suspension that allows for weight transfer so I can roll into the gas quickly. You may want to hit up ranger as he's made plenty of passes in stock cars on stock tires and could possibily provide a few tips.

I tried it tonight and spun like crazy. The best time I had was 12.5 and I was still spinning. I know with dr's i'll be in the 11's. Its hard dude

The tires I'm using are toyo proxis4 on the factory SS rims. I believe the treadwear is 300. I figure it may take another 2-3 mph to get in the 11s with an M6. I don't know where I'll find the addition power but I'm hoping that the new springs gave me a few.

I'm sure there may be a few more boltons I may be missing to get me closer to my goals.

I saw a GN run 11's on on regular street tires, not drag radials, not street legal tires, plain pepboys tires.

It was on and off the gas the whole way and ran mid 11's at some where around 140 mph.

that does not sound too safe :/

Given enough power I'm sure you can spin your way to 11s. With a bolt-on car, it's going to be extremely difficult working with limited power and traction.

11s on street tires. Possible?

Yes, it is.

Excellent time. Was this an A4 and what kind of weight?

It is a bit easier to do it with an a4 but it really is an impressive time for what you have nontheless. I really would like to see how many m6s have done it and at what raceweight.
It is hard enough with a bolt-on car to get low 12s but what chances do I have of running 11.999 with a bolt-on m6 at full weight? What et do you guys think I can run with my current combo?
Do you think I was maxed out on that 12.27 pass even with severely weak valvesprings? What difference would skinnies make?

3700lbs? Damn, mine is full weight and only weighed 3460lbs. BONE STOCK. Do you have a cage or some thing? Is it a vert.?

I've seen mid 11's on street tire, on the street no less, and it does look scary as ****. That did put down 600+ hp though lol.

Do you have a timeslip for your best run? I could probably see where you're lacking better if you posted a slip.

It'd be pretty hard to do at full weight without a lot more power. I'd pull some weight if I were you, at least the !sway-bar, !spare tire and jack, and !rear seats mod.

From what I've seen, skinnies typically will get you .1 to .15 reduction in ET, but that's on drag radials, dunno on street tires.

I think some weight reduction, practice, and good air will get you there. You'll need plenty of passes though... I made around 50 passes for 1 pass in the 11's on street tires, and even then, I just barely made it in there.

who cares? You'll wonder what in the hell you were wasting your time on when you run on a slick I assure you

Some people have personal goals that they want to attain. Don't knock them because they want to do something that isn't done that often.

Look at my car, If I wanted to, I could go get a credit card, buy an axle, drag wheels, slicks, and a kit and run 10's all day long, but I want to make it on the Stock Internal List first. That's my goal.

You've got your goals with your car, the OP's got his.

honestly it sounds like if you play with your rear suspension set up whether it be making is softer/firmer, sounds like since you think your making less power or your just not as fast as other people with similar mods that they might have a different set up for traction alone. as for what speed your lookin for to get the 11.999 thats different with every vehicle. just depends what tq #'s they got, gears etc. id say mess with the rear suspension, tire pressure and try to lighten the car a little bit, take the spare, jack, and other stuff out and leave em on the side of the track with your friends while you make your pass. id say doin that with your new springs should get you into the extreme low 12's or high 11's just depends on the driver

A couple years back I broke 3 rears in 1 season on dragradials. The car still does have the stock rear which is why I'm only running on street tires. I have another car to race so I really wasn't trying to go too far with this one.

Unfortunately my other camaro is down so I thought I'd have a little fun with the SS before the season was done. I really didn't expect it to run as quick as it did considering that my best time was 12.40@112.8 on dragradials a couple years back.

I didn't have any goals set for the SS before I made the 12.2 pass but out of curiosity I thought I'd see what others have gone in their bolt-on m6s. I don't want to turn it into a racecar so I think the only weight I would take out would be the spare tire, jack, and possibly try some skinnies.

If I could get a 12.1 at a raceweight of above 3600 lbs, especially with 140k, I'd be very happy.

It really is tempting to start modding the ls1, in fact, had it been an a4, I probably would've done it. I really don't want to start messing around with a stick car, it really can be hard on parts.
