Just looking for a comparison between the two tires. I'm basically thinking if the drag radial will hook as good(or almost as good) it would be a benefit on the top end. Am I thinking right???

 

I think you're thinking right.
What's your set up?

 

stick or auto car?

 

Radials are more stable during the entire run compared to a standard bias-ply tire like a QTP or regular ET Street.

My setup will be a 408 solid roller with a T400 tranny. It will eventually see some nitrous as well. Anything to get rid of the top end sway would be great. I hate that feeling. Would the radials also trap a bit higher then the qtp's?

 

radials all the way. get the 325 radials as so many are hitting the **** out of that tire with great results.

 

The 325's won't hold a full throttle transbrake hit on my N/A car. Great tires for a radial though.

 

I've run both and, on my car in the 1/8th mile, the radials trapped a MPH higher than the Hoosiers. I would expect the difference to be even greater in a 1/4 mile. The radials are at least 10 pounds per tire heavier depending on which size you decide to go with. I don't really notice this in the 60' times but the Hoosiers were ~.1 quicker to the 330' every time. The only thing I can think of causing this was having to accelerate a heavier tire up to speed. After the 330' mark the lesser rolling resistance of the radials took over and pretty much made up the time difference by the 660' mark. I never tried pumping the Hoosiers up tight to see if I could trap higher speeds like that because they won't hook at 30 PSI. Somewhat higher pressures did cut down significantly on the top end sway with them though. The sizes I am talking about are 26x9.5x16 QTP's and 275/50-15 MT Street Radials.

 

well take a look at two exteme examples. the guys down in TX running 5.6s in the 1/8th coming off the transbrake and the ohio boys coming off the transbrake at 19 psi. they had a hard time keeping it off the bumper.

its possible, just a bunch of suspension tuning.

I wish I could get them to stick off the t brake. I've got all aftermarket suspension parts, all stock style but I haven't had any luck getting them to grab off the t brake.

 

Nice video, It can be done I guess, just not by me yet

 

this is the case! unfortunately, many of us are in teh same boat.

 

I pulled a 1.520 60 foot on my M/T 275/60/15 radials off the transbrake at 3400 rpm, but the * on that run was b/c of a prepped track, cool at night with a good groove and rubber patch on the starting line. I've spun as much as I've hooked on these, it definately takes everything being set-up right.

The 325s are the hot ticket around here...know of a few local guys going mid 9s with them with 1.30ish 60's...and they ride like a....radial

i wonder how your nova would hook on the 325 radials? not too many hook that hard on the 275 but the 325 guys are putting it on the bumper.

 

Maybe the problem is with the 275's that I'm running then as they're not able to hold a max effort WOT throttle launch every time like the itty bitty QTP's were. The 275 is already too big (IMO obviously) for the back of my car. It's perfectly even with the fenderwell. The 325's would surely hit both on the inside and and even stick out beyond the fender. I've got them mounted on Bogart Welded RT's and I understand these rims stick out a half inch more than Centerlines, Welds, etc. Do the TA's have a larger wheelwell opening in the back than the Camaro's? Do the 01-02's have a larger wheelwell opening in the back than my 2000 does? Whatever it is, I just don't see putting a 325 in the back on my car and have it stick out beyond the fenderwell. That look just doesn't do it for me even in the search for superior traction. What am I doing wrong??? I ask this because I'm getting ready to purchase some full slicks in the search for traction when I go with the spool and 4.10's. Anybody got pics of 325's on Bogarts on the back of a 98-00 Camaro??? Thanks.

 

The above car has 410 gears in it with a TH400 leaving off the brake. That pass was a 5.56@124 with a 1.30 60ft

You would need to get a 10in wheel with a 7.5in back spacing for it to look right. 325/60/15's are the same size as a 28/10.5/15W slick. To run this tire on back of a 4th gen you have to cut the bump stop metal out and that is all. Maybe some masssssaging of the inner fenders some with a BFH...other then that, they do not stick outside the fenders nor do they touch on the inside. The above car is minitubed with offset LCAs.

 

That car leaves like a bat out of Hell on those radials. I can't hope for a launch like that as I'm SI and therefore power challenged. I am going to a full spool and 4.10's in the very near future though. I hit the track again tonight on the Bogarts/MT Street Radials and spun once and dead hooked once. 20 PSI in the MT's. Once again on the pass that they hooked driver error cost me a low 7.4x or possibly even a really high 7.3x timeslip. My driver delayed making the 1-2 shift nailing the rev limiter because the car was pulling so hard off the line. This according to him anyhow. 1.620, 4.788, 7.501 @ 90.228 on the 1st pass that spun of the line just a tad. 1.591, 4.824, 7.568 @ 89.70 on the Oops! pass. At least it hooked off the line. I'll still have the MT Radials once the spool/4.10's go in. That, IMO, is going to be the ultimate test of how they hook. My car is going to hit those tires hard with the new combo even though I don't have a transbrake. I'm anxious to see how good these 275 radials really are.
