TURBOV6 said:Finally got some track time on this new 6131e
Best 1/4 ET was 11.38@117.56 1/8 ET was a 7.10@97.57
I've always heard that if you didn't gain at least 20mph in the last 1/8 of the quarter that something was not optimized with the combination. But remember, the 6131E will not breather quite as well as the 6152 because of the smaller exhaust wheel....what you gain in spoolup at the start you loose on the top end..JDSfastGN said:was the 7.10 at 97 on the same run? If so that 1/8th is incredible but the 1/4 seems off for that time. Seems like its falling off somewhere.
murphster said:Nice times and mph. I assume you got your launch issues under control. What was your boost and timing? Did you try any different combinations?
That has to be one of the fastest runs on a GT61 turbo and stock heads/cam. It will probably be late spring or summer before I put a cage on and then a FMIC. At least I have a time to shoot for.

Boost was at 26lbs. Timming was 26 degrees. EGT's was 1620's. Did not have much time running the car, probaly will have done better if I tried to lean it out and up the boost a pound or two.

But either way, those are awesome times and for it to be your first outing with that turbo...I'm sure the humidity has to be killer there with all the rain thats been in Honolulu the last 2 months and this past week.
I'd be happier than a pig in chit if mine ran a tenth slower than that

Plenty of phone calls back and forth to try and resolve, not sure if he now qualifies as a dependent for me on my taxes this year

Blazer406 said:Lean it out??? EGT's 1620's seems like it is plenty lean to me...... You have a wideband on it? You go much leaner... chances of a piston liquifying and exiting through the turbine wheel goes up considerably... IMHO.
Blazer406 said:I am no master tuner... but would recommend a wideband to tune with..... although the EGT is probably better than looking at narrowband readings. The wideband is dead on.... where the narrow band is only accurate around 14.7:1 (approx 450 mv....or so) Someone more skilled at tuning could confir/deny if that EGT reading warrants you to need to lean it out... but IMHO..... I wouldn't like 1620... makes me nervous.....
yes and yes,but inmo there are much easier ways to get into the 10'sVery old post. Anyone hit 10s with the 6131E?
1 option would be to sell one or both and get what your want.I have a 6131e and a 6768.
