new data log from my quickest run today

[TurboCajun]

well I guess that is a good problem to have, that means nothing is BROKEN.

[Steve Wood]

Nope, it just means the turbo is too small to pump the volume of air that the engine can swallow.  Very few people have taken a TE 60 significantly lower than 11.100

[TurboCajun]

I guess I will be at this level for awhile, Thanks for all your help

[motorhead]

At this point you could start looking at maximizing what you have.  I'd consider porting the turbo and spraying a small amount of alky pre-turbo to extend the compressor map.  As well, you would benefit from a 3" downpipe.

here is a new log from 1/19/14, fastest pass to date 11.11 @ 119.9  1.584 60ft . I have change the converter and the two pressure switches in the trans and are now working. the three other passes I made today I spun at the line, after watching videos we noticed the only the right tire would spin after take off. now we have rear end problems.

Is this file from a 1/4 mile pass at the track? if not...have you got one from the track?

[Steve Wood]

it was

[TurboCajun]

time slip from that pass. Right lane

[Scoobum]

It appears you left the line at 3000 RPM...and the 1-2 shift was at 5600 RPM...and dropped to 5400...and the 2-3 shift was at 5700 RPM...and dropped to 5400 RPM. You're not getting enuf RPM drop. Your IDC at 85 percent is too high for only 22 PSI with 60's. Grumpy cracked a 9 with 60's and alky...and at the same boost pressure in my car and a relatively same size turbo, my IDC checks in at 60 percent. Fuel starvation mite be the issue for the high IDC. I'll assume this is a NL convertor...cu z your convertor slip checks in at 11 percent. Throw some 28 inch tires on it...and figure out your IDC issue...mite be a voltage issue as I'm seeing 12.8 at WOT. You're flying for only 22 PSI.

Dan was running a dual nozzle alky set up...makes a big difference

[PacecarTA]

that timeslip with 3700lb car should need 40 lb/hr per inj

on 65# injectors , i would expect to see an inj duty in the  60s - mid 60's

You're flying for only 22 PSI.

This isn't a fair comparison as 22 psi with high flow heads such as his GN1s present a much lower restriction than a set of stock heads - there is a lot of air going into that motor.  If I had to hazard a guess I would say he is running out of fuel pump capacity, not injector, as the ECM is compensating for the pressure/flow drop by hanging the injectors open longer.  I'd get a pressure transducer on the injector rail and/or measure the flow of the pump.

[Steve Wood]

given his chip programming, the dc% is about what I would expect

[TurboCajun]

the converter is a lock up. and I do need to check on the voltage issue.

[Steve Wood]

try to connect a volt meter to the pink/black wire going to the ecm or any of the pink/black under the dash....someti mes the scantool reads low due to the ecm conversion from digital to analog and the meter will show the correct voltage...and sometimes it is a bad connection or ground....no need to panic yet
