Who is doing it?

Combo is 575ish HP, with nitrous, S60 4.30s, 28" DR.

Either the 275/60/15 or the 295/55/15.

Who's doing it? Looking for 1.50 or better short times n high 10s at my elevation..

With that kinda HP, with a bottle-fed LS motor, you are making well over 600 ft-lbs of torque at the rear wheels.

I would go with slicks if I were you, and don't look back. At the power level you are at, a lot of people have traction issues with the T-56/radials.

Alan that owns ThunderChicken is and now that I have good rear shocks my car hooks better on the street then it ever did with bias tires. Not to mention it drives on the street way better. I think the key to hooking a radial is good suspension and bias tires are just a band aid IMO.

Any EXPERIENCE with radials and a stick you'd care to enlighten us with?

I remember Cartek (LS1 company) built a H/C LS1 6 speed a while back making 507/433. Had a 12 bolt with 4.56s, 28 inch M/Ts. Best time was 10.32 at 132, 1.43 60 foot. He would leave at 6000-6500 each time.

This^^^^

Iv been low 1.6s high 1.5s out of radials and single adj rear shocks. Im hoping to get some AFCOs and shave a few pounds..then see what it can do..I like radials better..just a lot smoother driving and going down the track!

Yeah, leaving with enough RPM to cut a 1.5 sixty is going to be tough with a radial design. The sidewalls are just too stiff for the initial shock of a high RPM stick shift launch. Just the way things work. That's why you don't see dragsters and chassis cars with radials. A bias ply tire is used because it works, not because it's a "band-aid" for suspension. The soft sidewall construction of the tire absorbs the shock and hooks the car up, while a stiff sidewall will just spin. Don't get me wrong, radials can be made to work wonders on cars, plenty of people go fast with drag radials, but I doubt many of them are stick shift cars. They work great with auto cars that preload the tire and suspension. Contrary to popular belief, bias ply tires are also easier on driveline components than drag radials are.

Not arguing or anything...Iv heard everything about radials and 6 speeds..But a T-Braked Auto hits the tires just as hard..Like you said its all about suspension set ups and tuning...And VERY true about a bais ply being easyer on the driveline..

Heres a 6 second car on raidals..

Dang Dave has a T56 in his car?

And a transbrake auto does hit the tires harder than a footbrake, but it still transfers power through the converter, which doesn't hit as hard as a on/off kind of clutch launch which puts the power there right NOW. Torque converter takes some of that abuse leaving off the transbrake.

No 6 speed..Just a High 6 second car on Radials..My point was agreeing with you saying a car can be fast on radials it just takes someone that knows how to make it work. I 110% agree with what your saying with converter slip..All I was saying it CAN work..lol

The Cartek video tells you what tire its got in the video lol

Yes I am with Madman custom valving and now the car hooks better on the street in 40* weather with radials than it did on the track.

I used to think that to when my car dropped .2 just by switching to bias ply on stock suspension, then I saw this with radials and a M6.
