Anyone running 11's on street tires?

I'm just wondering if many people have done it?

and how hard would it be?

Thanks

It is very hard to hit 11s with street tires.

I have seen it done twice.
First time was when I was a freshman in high school and this guy had a white mustang gt(fox body). He had a cam, AFR heads(with extensive head work), gear, and a supercharger pushing 14 psi. I went to the track one time to watch him run. First run he made went something like 2.2060ft 12.12@120 mph. Well finally he managed to work the clutch well enough to get a 1.99 60ft and ran a 11.89@121mph. I would not have drove that car to save my life. He was running a true street tire, no drs or et slick or anything. I think they were goodyear eagles on 17inch cobra r rims.

Then I have a friend that is 17 and attends Cardinal Newman High School in South Carolina. His father owns the local dodgeland. My friend in highschool drives a 2001 Dodge Viper GTS. Well he ran a run that went like this- 1.9x 60ft and 11.9x@121mph.

I have 4.10 gear and can't come out of the low 13s on street tires.

Thanks, that's my new goal.

I might have put the 125 jet's in, and go down when the track prepped.


What do you guys think?

A 1.9 60ft and a 125 shot, would do the trick?

I know a friend of mine has a ls1 with a 125 shot of gas and slicks. He runs 7.80s in the eigth. Another one of my friends runs two stages of gas on an ls1 and has been some 7.10s in the eigth but about two months ago while running the gas he separated his intake.

You have a friend in High School who has a Viper?!?

Anyway, to run 11's with street tires, you'll probably need a lot of power to get you down the very end of the DS as fast as possible as you'll be spinning or not going to WOT at the first half of the track. The track will need to be prepped very good to. This weekend I was spinning a few times on my 3rd to 4th gear change. The car that went down the strip before me might have leaked something on the track. It scared the crap out of me. I have 255/50/ZR16's (@16 psi) and posi. I think it will be easier to run 11's with an automatic because when I let off the gas, shift, and then floor it, it just wants to spin all over.

There is a guy from Belmont, NC running 11.8@118 mph on street tires. Its LS1 automatic with a 150 dry shot I believe. I believe he's running 1.6 60' times!?! :bow:

:D

357 RS- Yea he got the car brand new when he was 16. It is a red 2001 GTS with a few mods. His dad owns the local dodgeland, but drives a 12 cylinder mercedes.

bgoins11 Trans Am- Is that with "true" street tires? What I mean is same tires that come on the car from the factory(No Drag Radials or Et Streets). I find it hard to imagine hitting 1.6 60ft times without power and traction. I know 3 guys that run 9s@140+ with Mickey Thompson ET Streets.

There is the post talking about it!!! It is one fast ass Z!! :bow:

I read it, still hard to believe but not calling anyone a liar, I would just have to see it. I have been to the track many many times. I have seen Mickey Thompson Sportsmans turn 1.7 60ft times but they had a tread with of 13 inches.

His car would be alot faster with a stall and slicks. I don't know why he hasn't changed it.

my 3900 lb., NA 74 firebird ran 12.02 last week on ET streets. i'm hoping it'll make an 11 second pass this wednesday night. the 60 ft. on that pass was 1.668. on "true" street tires, my 60 ft. times would be 2.0's or worse. :)

rumair- Good luck on getting the 11s man. I am like you, with slicks my 60 fts are in the 1.5 range(on n/a runs), but with bfg radial tas(275/60/15) I can't even get a 2.2 60ft.

Believe it or not my N/A run in my sig, was done on the Factory F-1's I have on my car now?

I've gotten a lot of 1.9's and a 1.8 when they prep the track?

Yeah, it can be done. I love running true street tires. Saves on parts breakage. My previous Malibu with with a 400 SBC and a plate nitrous kit sneaked into the 11s on Dunlop all season radials. 2.0 60 foot time.

My current Malibu with the 383 and blower should be good for only a low 12, though- it's just not as strong. Yet. It's also run only on true street radials- no DRs, no slicks. It still has the original 7.5" rear in it so you know I'm not gonna be doing any Bansai launches.

Taking a full 2 seconds to cover the first 60 feet doesn't leave much time to complete the rest of the track. You need a LEGITIMATE 450 HP and a boatload of torque to get the job done in a street car of typical weight. Now if you can get it down to, say, 3000 lbs., the job's a lot easier. My 'Bu weighs about 3650 with me in it.

Steep gears? Forget 'em. No help whatsoever. You'll just spin worse. My old Malibu and my current one have 2.92 rear gears and a stock stall converter in the TH350 trans. The key is to be able to get the pedal all the way to the floor in 1st gear and be right on the edge of the tire's adhesion all through first. You want the hardware to do the work, not be feathering the gas with your right foot. Just my experience.

I found a article I had read about a month ago. The guy has a 99 ACR Viper with a Paxton supercharger. It makes 750 rear wheel horsepower and still has the stock camshaft in it. They ran on his bald Michelin Pilot tires(not drs or slicks) and ran 11.5s with a 2.0 60ft. When he was able to get a 1.8 60ft time on the Michelin Pilot the viper hit 10s(first 10 sec run was a 10.999 then it went a 10.92@134)) on true street tires. That is awesome, to be able to run 10s on non drs or slicks.

This is kinda what i was thinking... When I had 3.73's in my car with the m6 I could do hellacious burnouts and no matter how I drove the car didnt like to 60 ft good, kept on spinning.. I changed to 4.56 and the car didnt like long burnouts any more, and 60 footed regular 1.9X on BFG radial T/As. (of course I still had to launch just right to get decent 60 ft times.)

But hey...If that guy is getting those times...thats cool as hell, I know my buddy would love to get the same out of his A4 LS1!!

I am going to try it next time I go to the track. My car has been 1.82 60'12.87@108mph on radials with the cutout closed N/A so I think spraying about 25-30' out with a 125 I can go 11.90's on some Kumhos. I ran it last weekend and only sprayed to the 1/8th and ran 11.67@116mph on ET streets with a 150 shot. I don't have a rollbar so the local track keeps threatning me about running 11's. I don't think they will complain too much about 11.99? :D

Steeper Gears work if you are going to race with slicks or a tire that is a sticky compound. Don't worry about steeper gear unless you are going to get slicks. With Steeper gear you pick up time running on slicks.

Last weekend I went 11.99 @ 115 on street tires. That is the best she has ever hooked for me. I usually run 12.1's to 12.3's on street tires.......Comp T/A's

Cam only LS1 with most bolt ons.....1.89 60'. Of course this was on a well prepped track and 50 degree weather.

She will go 11.7's on bald DR's at around 116.

Later, Stu

Nice run!

Only if they would have prepped more of the track might have dipped in the 11's:cry:

I kept getting pretty good launches but after the 60ft mark it would start spinning.

2.157 8.572 87.06 12.935 115.66 spinning all the way down

1.859 8.064 90.00 12.347 116.58 should of been the one, but had to turn off the n2o for a second due to spinning after the 60ft:cry:

2.046 8.329 89.92 12.612 116.92 spinning again

2.029 8.045 92.55 12.245 118.44 only if I got a 1.8 :cry:

Might have to get some Nitto's pretty soon, the F-1's are not going to last much longer.

It just takes a very good power/weight ratio. You can't launch hard, so you have to make up the time at the "big end". My car runs 11's pretty easily on street tires, but the times are very inconsistent and the mph is way high compared to the ET.

What kind of 60ft/mph do you get?

Thanks

With street tires (255/16 Comp TA) my best 60's were in the low 2.0's. Some people are in the 1.9's. This improves to mid 1.5's with ET Streets, so the advantage is at least 0.5sec.

Rich Krause

Almost there;)

Not an F-body...but ran 11.85 @ 112 MPH back in Oct of 2001 at E-town. 99 Cobra with bolt-ons, gears, and BFG Drag Radials.

Bob Crosby- The new Cobras must respond well to mods. That thing is running strong man. Good Job and nice Car.
