11.48 at 120.82 with a 1.53 60ft, why is the et not better?

Whats your alternator voltage throughout throughout the run?

for having a 44 on pump gas.w/drag radials is why but it,s not bad.you were hooking you need bigger turbo 6152e.and you will see better et,s.i may be wrong but i believe youre turbo is runnig out of steam on the big end.a 61 or 6776 and slicks would cure that!

This could be the case. We need to see the incrementals, and this will tell us.

Car is probably flat to the 330. Post the complete time slip.

Get the 330 down, the rest follows.

The track I go to only has 60ft, 1/4 mile ET, 1/4 mph and 1/8 ET and thats it.

I don't know what the voltage is at the alternator throughout the run, but I could tell there doesn't seem to be a voltage problem after changing the
battery. The voltage at the battery with car running on idle is over 14 volts.

Do you have a scan tool? You need one if you don't. Not only will it tell you your battery voltage but you will also be able to approximate the information that your local track isn't providing (1/8th MPH, 330' times, etc.).

Yes I have a otc 4000e as a scan tool which it does give me my battery voltage but I don't see how I could get the 1/8 mph, 330' times, etc.

Thanks

I should have been more specific. You need something like Turbolink, DirectScan or PowerLogger. They collect LOTS of data including elapsed time, distance covered and MPH. You can see BLMs, injector duty cycle, MAT, MAF, coolant temp, TPS, etc. and so on. You can also record boost, EGT or just about any other analog input with PowerLogger.

Maybe a little too rich at idle and launch could cause slow turbo spoolup?
