He picked up over 2 mph in the eighth.
I thought he ran a lb or 2 more boost too?

Well I went to the track friday night.
Ran a 7.35 at 97 mph with a crappy 1.79 60 ft ( Could have been a 7.15 or so with a good 60 ft ) at 18.5 lbs of boost. Track was really bad that night as we had several blow ups on it.
Did not lock the convertor either. The convertor is a mystery convertor to me as it was in a car that I bought. Its a 9/11 lockup with a 3000 stall or so.
Let me know what you think.
Here is a powerlogger file. PLX wideband setting with a 3 bar map
I looked at your log. Something doesnt seem right with the boost. I have a 6262 journal bearing turbo and my boost is at 5lbs at 3,000RPMs. Yours still shows vacuum. Have you compared your boost gauge to what the Power Logger says? Another way is to look at the voltage on the PL screen for the 3 bar map on the "Config and Download" screen with just the key on. The volts would be 1.6 volts in a perfect world. But should be between 1.5 and 1.6. If it is lower than 1.5 volts than it is reading low. I think your PL may be reading a few lbs low. But post back the key on voltage on the PL.
What is you duty cycle at on the big end? You have that thing running good!
That log is a run with the old 9/11 lockup converter. It was still in vac at 3000 because the converter was super super loose.
I will check the volts on the config and download page tho and see what its reading.
If the converter was loose then the boost should have been even higher. I think something is up with the boost on your PL or MAP could be goofy. But your boost seems a few lbs low for sure on the PL reading.
Map volts key on engine off fickers between 1.526 and 1.531 volts.
Boost gauge matches pl readings from the times that I checked before, but I will check again here in the next few days.
Dang injectors.... well a street car it is for sure!
I knew that turbo would kick butt, how do you like the ported shroud sound and compressor surge control when passing cars on the highway?
Do you plan to work on the suspension and 60ft, do fuel upgrades, or enjoy it the way it is for now?
If the converter was loose then the boost should have been even higher.
Timing and increased CR will increase the engines torque while off boost also and can raise the stall speed before boost hits.It is possible that a really loose converter will not load the engine to produce boost. Just like rev'ing it to 4000 in park.......no load to produce boost.
