AIght well I went to the 1/8th mile track today and ran ok. Not great at all actually. Well, I wanted to know if someone can guess my qtr mile using info from my eigth mile run. Here's my best one:
60' - 2.213
330 - 6.0
1/8th- 9.270
mph - 78.28

I know my 60 foot sucks but I was on M+S tires open diff.
Thanks in advance.

here was my timeslip from one of my very first passes that is similar to yours but a 1/4 mile timeslip.

SD
R/T 0.403
60FT 2.401
330' 6.180
1/8 9.226
1/8 MPH 81.590
1000FT 11.821
1/4ET 14.033
1/4MPH 102.300

Now, what boost level were you running? Since your 60ft time is 2 tenths faster but your 1/8 mile is the same i assume you were running less boost. I was running 14.7 psi on the stock turbo.

the quarter mile convertor says 14.3 but you get the idea.

Awesome. That's is what I'm expecting on street tires.
The run was ass. I had wheel hop on my launch and on my 1-2 upshift. I also went into 3rd kind slow bc of my worn motor mounts causing me to mishift.
Hmm. I wonder why my trap is so low compared to you guys'.
Boost was at 1bar. On a S13 SR t25 with the typical bolt-ons.
Thanks guys.
