Went to track last night with new yank SS4000. Car has headers Y pipe 12 bolt with 373 Gears Umi suspension,tune, lid,and a flowmaster.


60' 1.61
12.28 @ 107

 

Nice 60 ft. What converter was in it before, stock? Just wondering what your gain was from the new mod.

 

It was a Yank SS3200 and sent it back to get restalled to a SS4000. The best 60' with the 3200 was 1.80. The car went from 12.74 to 12.28 .

 

Good time! But it's weird your MPH is kind of low.

 

Ya it's heavy 12 bolt, sub frame connecters and umi torque arm,panhard bar, it might be a extra 150#.

 

Wow, that's a big gain from only 800rpm's more of stall! Almost sounds more like going from a stock converter. Ya gotta love what picking up 2 tenths in the 60 does to the big end. Guess I won't go mild with my converter selection!

 

Nice time man!!!

What kind of tires were you on?
