I have a 97 Supra 6 speed with an SP63/.81AR, SP fuel system, stock cams, stock head, no cam gears, stock wheels, and Tien Coilovers. I was running on VERY bald 275/40/17 drag radials and could not hook worth a shit. In the past, on 1/2 worn drag radials I effortlessly cut a 1.602 60 foot time. All runs were made on race gas and EGT's never went above 750. NOTE: READ BELOW FOR THE INTERESTING POINT.
I took my Supra out to Desoto speedway this weekend. I could only get in 2 runs on saterday since there were too many people and I also made a few passes on Run Sunday. Big thanks to Horacio for all the help at the track (you are the man and a great friend).
The first pass on Saterday I accidently left the bost controller off:
1.94 60 60 foot time
7.619 1/8 mile et
98.45 1/8 mile mph
11.608 1/4 mile et (pretty good for 14 psi)
123.23 1/4 mile mph
The second (and last) pass on Saterday with 27 psi I ran:
1.819 60 60 foot time (missed 2nd!!!!)
7.535 1/8 mile et
99.43 1/8 mile mph
11.396 1/4 mile et
129.75 1/4 mile mph
My first pass on Sunday with 27 psi i ran:
2.014 60 60 foot time (!!!!!!spun)
7.362 1/8 mile et
103.84 1/8 mile mph
11.015 1/4 mile et
134.64 1/4 mile mph
After that my 60 foots went to complete shit
(as if they could not get any worse.) and my bald drag radials would not hook at all.
The most interesting thing I noticed is that on a fresh set of drag radials I can cut 60 foot times in the 1.6's and looking at my 11.0 pass it looks like I should be able to pull off a 10.60 or 10.50 pass using 27psi.
Oh, by the way, I just got my HKS EZ in the mail (thanks Nero) and will be installing that since I am unable to hit more than 27psi with my current profec B controller. Once I get it installed I am going back to the dyno with the help of Angel and hope to hit some dyno numbers close to the 650 range.
I have a set of ET streets in the garage but I think I am going to get another set of 275/40/17 drag radials and see how deep in the 10's I can go with radial tires.
I may get a second set of rims so that I can run my S03's on the street and not have to wear out a set of drag radials every two weeks before I can even make it to the track!!!
email me if anyone has any questions.
