1990 350 formula w/ kn, headers, chip, power pulleys, 160 thermo, 4.10's w/ auburn pro carrier,.....and 150 hp nitrous express...what time would it run motor and N2o!?

 

You got a nice car, tho I woulda only went with 3.73s or 3.42s I think the gears will hurt a tad. I say 13.9 if you can hook up N/A and on the juice maybe 13.2??? I would run a 75 shot if you want ur motor to live a little longer tho.

 

Yeah, 4.10 is too much gear for a TPI+700R4 combo. I wouldn't go with more than 3.42. With traction high 13's shouldn't be a problem N/A and possibly mid to high 12's on nitrous. Still think you'd be much happier with 3.23 or 3.42 gears unless you're planning on adding a Superram or Miniram.

 

got back from the track ....ran a 14.03 with a 2.11 60' best....i did notice thats too much gear for a tpi...i went from a 5.o to a tpi car..so ya..lol..3.55's would be nice, i didnt get to spray the juice though.
