Well after 3 trips driving to and from the track and about 20 passes my M&H Musclecar drags I have only managed a best sixty of 1.79

I am thinking about another street/strip tire that I can drive everyday and was thinking about the following:

27 inch tall Hoosier quick time tires. (Not the pro) or another 27 inch tall tire

Has anyone used these tires on the track/street? do they hook well?

I need something I can drive on the street and in slightly wet weather yet hook well on the track.

I have also got the car back to full street trim. front and back seats are in and every panel.

I weighed my car on Saturday and it was 3480 with me in it without back seats and under dash panel and 1/4 tank of gas.

Probably going to hit 3500 even with cats and airpump back in the car. (Damn emissions police!!)

4.10s should help make up a bit for the ~20 RWHP loss through the cats and extra weight. With a 27 inch tall tire I should be right around 125mph at 6400rpm. (motor peaks at 6000rpm)

Goal is high 10's to low 11's@~125-126mph at ~3550 pounds.

Going to be fully emissions legal, FULL interior driving to the track, racing through the cats and going home.

Any suggestions for a tire? anyone try the MT 28 inch Drag radials yet?

01-z uses the 27" QTP's, obviously he'd doing well with them. not sure on their street capabilities in terms of water, i would assume same as an et street..basically anything over a bit of dampness and you're in trouble.

I gotta weigh my car,I can only imagine what it weighs

i cant believe the m&h did'nt work for you. my bud just put them on his stang and is lonching like mad. guys that were beating him by a car,he is now beating them by two. i'm spraying in first gear on the streets with the cheeter slick and hooking. well....i guess not everything works for everyone.

CHRISPY

I am probably making a fair bit more power and especially torque on motor. ~466RWHP/~440RWTQ)

Also tracks up here (with the exception of one) tend not to hook as well as the ones I have been on in the states.

CHRISPY

You have K-member/HALS and everything right? Best way to check is to throw it on a scale

I still have heater, airbags, stock suspension, stock K-Member, heavy BMR Extreme TA and subs, powersteering etc etc.

With a full tank it is going to come in at 3550 pounds with me in it and full interior. I usually try to race with about 1/3rd tank of gas.

Chris.

i think their scales were off, based on what i heard a couple of the guys say what they weighed them to. i think you are heavier than that.just an fyi.

You have 3.73's now? I would keep them and see how they work? With smaller engines gears help wind out the motor since smaller engines need rpms to make power.

When I had my 422ci I made 472rwhp/505rwtq locked and went 11.02@123mph at 3550 raceweight... I had 4.10's and 28x10.5 slicks. I think the car ran thru 1st gear too fast. If I could do it all over again I would run a 26" slick and a 3.73.

John I agree,more gear can hurt in an auto..
I ran 4.56/28 and felt it went threw the gears too fast..

Pipster I'd try the M/T 275/60/15,its 28X11X15
I think you'll be amazed at how well it works on your car,both for street/track.

Pipster,I'm weighing my car this week..
We'll see what she weighs,Any guesses buddy (JS 340lbs help me)

Actually i've been driving my car about 30 miles to the track and back home on ET Streets and I've never had a problem. I've run into water a handful of times and I haven't had any problem. Just stay part throttle through the water of off the throttle before the water and it will be fine.

I've finally figured out the ET Streets after struggling with them for the better part of the year. Running 26X10.5X15 tires with no tubes at 12psi. The tires do not like a big burn off. Took me forever to figure this out. Just a quick two second burn off and I'm pulling consistant 1.68-1.70 60' times with a little bog. I'm sure Chris ARE 346 is putting about 100 more horsepower to wheels than I am, and less weight, so I don't think there would be any kind of bog issue.

CHRISPY

hmmm you are probably correct.

I was adding up the extra weight compared to what I took out and it didnt make any sense.

Weight added:

6 point cage: 80 pounds
Battery in the trunk: ~20-30 pounds
Kill switch
airbag
heavy torque arm, subs, clutch, driveshaft

Weight out:
convo pros - 60 pounds?
AC, Swaybar: 25-30 pounds
lightweight carpet: 20 pounds

I am probably forgetting stuff. I'll weigh at Trafalgar this week and see what it comes in at

Convo Pros with skinnies up front and 26X10.5 slicks in the back saved me 90lbs over the stock 17X9's.

The A/C and sway bar are probably 30-40lbs together.

CHRISPY

The M&H tires I am running are heavier than slicks. The swaybar was ~15 pounds and the AC was ~24 pounds (so ~40 total)

thanks for catching that

Maybe I'll pick up a set of 26x10.5 ET streets and be very careful to drive in dry weather only. Track is 1.5 hours away.

FYI, the 26X10.5X15 ET Streets are 19lbs each. Part number on them is 3752. I've driven on them to California speedway which is about an hour and ten minutes to and hour and a half depending on traffic and never had a problem. Since they require very little burn off they should last you a while despite the long trip to the track. I have the 15X7.5" convo pros and the tires on those rims tuck up under the rear fender well.

CHRISPY

That is the same rim I have What psi you run on the street? I usually run 15psi hot at the track

bad2000ss

iTrader: (6)

I run at least 30psi for the street. I've been running 12 cold/13 hot at the track, but I should probably go up a pound or two because I bog little off the line. Like I said before, you're probably putting 100 more horsepower to the rear wheel than I am, so 12 psi cold might put you right in the sweet spot. I wouldn't go any less than 12psi. The rear gets really sloppy at the top end with any less than 12. I am still running the stock rear sway, if you have a heavier replacement, you might not have the same problem.

CHRISPY

Here is the plan

4.11 gears 28 inch ET Streets (27.6 actual height)

Dual 3 inch carsound cats on the car and full exhaust with single cutout in intermediate pipe

FULL interior (All panels, both front seats and back seats, carpet, headliners, etc etc etc)

6000rpm shiftlight

Hopefully high 10's low 11's emissions legal without changing a tire

I have two sets of tires..

4.30 gears..

I run the 27 x 11.5x 15 in the street class that we run in brackets. I also drive around on the street with them also.
I've cut a 1.55 last year with old combo..They can hook if everything is right.

I also run a 28 x 9 x 15 et drag.. I screwed these rims, and have a lot of luck with them.. They measure 27.7 and have been great. I've lost a little 60 ft with them, but that is my fault. We picked up some torque, and I have not gotten the torque arm, air pressure, setup right..

I wish you were still down here, you could try the 27's..

CHRISPY

I am going to be coming down in August for a visit I'll meet up with you guys then

I have 4.30's and was thinking of going to a 275x60x15 et street radial. Is the 4.30's good with that size tire? I have a small tq cam so I dont have to rev to the moon so I was thinking for consitant times the taller tire would hook better. Chris, I am glad I read your post because with all the hype on the m&h race masters, I almost forgot how bad they sucked on my old 69 cheby truck I use to race. Best she would pull on m& h was 1.89 , swithched to a 28x10.5 dt drag and went 1.76's and that was just all the truck would do.
