Converter is too tight probably. Try leaving right off idle, stab the gas as hard as you can to get it to flash as hard as possible, it may help.

Is it spinning or bogging??

On N20 or on motor??

Seemingly its a cammed/n20 a4 car. The converter maybe tame for the track but if your do alot of street driving I bet it does have excellent street manners.

3500 is too tight, even on spray. I would get the SS4000 from Yank if you want a good converter that will take a decent shot and run well on motor.

What's your pinion angle at? What hole in the relocation brackets are the LCAs?

Having the arms in the lowest holes works o.k. for slower cars, but the faster you go you'll find that moving them up some will be beneficial.

you probably don't have enough air in the tires. Put them at 20 cold and try that, the larger sizes you can get away with low air pressure, but the low profile ones don't like that at all.

Need like 18-20psi in those tires. Car is a pig at 3500, probably no weight transfer.
Get a set of Hals all around, set the rears at 6-8 and the fronts at "0", she'll 60' for ya.

I thought just the opposite ... prob explains why I can't 60' better. Mine LCA's are in the lowest relo bracket hole, as well. I need to pull my head out of my a** and not assume these kind of things. Car is in the shop having a Yank PT4000 installed, so, now the pinion angle/steepness prob will play an even more important role.

orangefun, good luck with your times. Please post back up what works for you.
