give us a break down of the time slip... do you have a wide band on the car? what ind of tires? open diff might not be helping the situation..

Ya sounds like extremely short shifting or BAD Bad tuning, 20 psi on that motor shoudl be over 500 hp depends on what you have pushing it, so 105 sounds way off.

lsd will help alot along with bfg's. but do not miss a shift, for the w-58 hates it.

Interesting.

I ran a 13.8 last week in my MK3 which recently dynoed at 293 RWHP.

Here are mine for comparison.

60 ft 2.124
1/8 et 8.952
1/8 mph 80.35
1/4 et 13.833
1/4 mph 101.08

The big difference I see is our 1/8 times since I would have been well ahead there but you would have closed the gap by the end of the 1/4.

Did you have major traction issues in 1st and 2nd?

I was also at 12 psi by the way.
