i have a 2000 5 speed with a ypipe, gutted cat, custom b pipe, and an hks rear section. before this stuff i was trapping like in the 94-95 range, well i went out on friday and the best i could get was like a 91.8. i think it's the VIAS not working but i'm just wondering what you guys think. i have the new coils on there, with new plugs too. just curious. my times were horrible because i was baby launching the car and didn't really try to get a good 60' time. i just wanted to see what i could trap. so any help would be great thanks

 

Were the conditions the same as when you can the 94-95 mph trap?

 

better conditions, cooler less humidity

 

I notice that u said babying the launch....trap speed doesn't rely on launching or 60ft...unless u seriously didn't go WOT after like 100ft or something...then of course your trap will be a little lower...

definitely something is wrong with your top-end

 

Im going to guess your VIAS, but then again your stock 94-95mph trap is rather high for a stock 5th gen 5speed where as most trap 92-93mph.
