Im just curious to see what are the best times out there on a stock diff on pump gas. please include your power level, tires you were on and setup.

ill start:

11.9 @ 120mph
496whp
all season kuhmo 255-40-17
inline pro kit

 

Don't forget to include generation of diff.

AP1 vs AP2

 

Im sure Inline pro did a 10.70 on a stock diff if i recall correctly. Not sure what fuel they used though.

 

sorry, mine is ap1... is the ap2 stronger or something?

 

The end caps that hold the lsd inside the pumpkin are more reinforced than the ap1's not a whole lot though.

I did a 13.5 at 103.5 last night but I only launched at 4k. Wheel hop which is bad for the diff kept happening to me all night. I need to figure out how to eliminate it. Would springs help guys?

 

what tires are you using? do you have big rims with a real small sidewall? that creates wheel hop. i have stock suspension. the bigger the sidewall the less chance for wheel hop atleast thats how it was for me when i raced FWD, im still very new to RWD drag racing

 

I have the ap1 stock rims and tires, I am looking to uprade them both with a 1" drop. So if you have any recs on 17 " rims with caps and springs let me know I have been searching and have not yet found anything I really like. I don't want to spend a ton of money on them.

So far I like the Rota rims for the money and Swift springs.
