That's really the only good thing I can say about my first ever trip to the track. I was hoping to get into the 13's, and after my first run I thought I could get there.

My first pass I bogged slightly coming off the line, and felt like I was driving way to conservative. But it was my first track experience, so I was trying to get a feel for it. Funny thing is, that turned out to be my best run of the night...14.350@104mph

When I tried to get more aggressive that's when I started having problems. My next pass I thought I actually did break something. I dumped the clutch at the line at about 3k rpm, floored it, and the car just sat there I thought for a second I had blown up the clutch, but I was just smoking the tires. The next pass I babied it off the line, figuring I could make up time in 2nd and 3rd. When I shifted to 2nd I again smoked the tires.

That's how the rest of the night went, never could get the car to hook up. I had put my original 16" Perfos back on for the track, because I didn't want to burn off my good 17" tires. I'm guessing 205/55/16 Michelin MXV's probably aren't ideal for track use

I can get a good deal on a set of 16x6.5 steel wheels. I have access to many used tires. What would be the fattest tire I could squeeze on these rims for track use? Am I still going to be disappointed? Should I just bite the bullet and get a LSD?

For drag racing only--M/T ET Drag, 24.5x8x15. Cut your 60ft time down by a half second or more, and you will have full traction by 2nd gear onwards.

What do the steel rims come on stock? Volvo or other make? 8" wide

[boxpin]

Yes, I have been searching for steel rims...what do they come on?. Those look awesome.

[Volvo5.0]

The widest 15" steel wheel I've seen is 6.5" wide. I know Volvo makes a 7" wide 16" steelie. Anyone know of anything bigger?

Do not put a heavy ass steel rim on a drag car. Get some light spun or forge rims.

They are better than 17's, there was 4 tenths and 5 mph difference in my R when the only change was the wheels.

Steel vs. Volans

Same tires?
Same day?

A week apart, track conditions were close enough to not be an issue. Tires on the 17's actually had good tread, 15's looked like this....

Those steelies are 7" wide. You don't really need anything bigger to fit an 8" wide slick anyways.

And they came on what car again?

[BlackT5]

Guess those 15s wouldn't clear 302s.

[Mesoam]

should be able to stuff these in

I guess you could swap the brakes back to the smaller rotors for the track, but it seems like it would be a PITA. That's why I was thinking about the 16" steel wheels. Until I get a set I'm not even 100% sure they would clear.

Yeah, I was looking at the Hoosier's at the Tire Rack http://www.tirerack....R6DDR&tab=Sizes
Our shop has a wholesale account with Tire Rack and we buy A LOT of tires from them. Maybe I could get a "special" price. Can't hurt to ask

[fischmama]

Its though to launch the car at the track with the quick spool of the K24. I had the same issue. I did long burn outs to get the tires to be as sticky as possible. I never got to finish the second run, and blew the diff and a hole in my transmission.

If you put hoosiers on the car with a stock diff you will almost certainly ruin it, esp when you are going to dump the clutch to launch.

Yeah, I think I'll hold off on the slicks. This is a DD and will hardly ever go to the track. I was just curious, and it turned out to be very frustrating. I'll probably get a LSD though. Since the car gets pretty squirrely on the street it may be a good investment. Then maybe I'll look through my stacks of used tires for a set of 225/50's and give it another shot at the track.

I think it's time to go to a bigger turbo so you can atleast pray for some traction. ;-)

[gmsgltr]

no hate here lol... just asking...

isnt that very slow for all that you have done? this is the car in your sig right? built rn k24 etc...

even if you dont get traction (i know thats the main problem here) shouldnt your trap be higher than 104? how much boost?

Trapping 104 was really one of the only things I was happy with. I didn't read all 16 pages of the pinned "1/4 Mile Times" thread, but looking at the list on page 1 made me feel OK about my trap speed.

Obviously I was disappointed with my first trip to the track, but I really think if I can get a LITTLE traction I could get a respectable run. Remember too...we're only talking about a K24. Most put that turbo in a class with the 18/19T. I love it though, especially for a DD

[TRACStar]

My best trap to date out of my 3 or 4 trips was 103mph with an auto and a 16T.

I really want to go again since I now have a couple more little things done to see if they made any improvements.

There should be more in your setup, time to start playing with the tune.
