Well it seems to me I have too much converter slippage on the bottle.

Setup is th400, 3.89's, 28's and i trap 134ish and im hitting the 7k rev limiter right at the stripe. To me and everybody else it looks like people are going 140 or so with the 3.89's but i go 134 and am already maxed out.

I calculated converter slippage at 12%. Does this seem good,bad,average for a nitrous car? and what do you big shot guys like to see?

Just a little weird to me, so I wanted to get your guys' opinions.

 

Might be alittle loose, What does it fall back to on the shifts?

Th400 should be about 1500rpms (shift @ 7000 should come back to 5500)

 

Come to think about it, I havnt even payed attention to what it falls back to. I have only made two passes in the car with the current setup. ill have to check next time.

Just guessing i would say it is only dropping back 1000 or so.

134 with 3.89's and on the limiter just seems weird to me for some reason

 

How did u calculate ur converter slippage?

 

rpm on the datalogger vs. optimum/theoretical rpm required at 1/1 lockup at that speed?

 

in one ear and out the other...lol

 

anybody else have any opinions?
