91 Galant VR4

Thanks, the tranny shifts great. I will figure out a launch before it sees the track again, then I will try some no lift to shift stuff.

Looks great John! is it a little laggy in 1st off the line?

Not really, the first run of the day it spun in 1st. Then the 2nd run I need to launch about 1500rpm higher then I did, they just finish track prep so there was a lot more traction.

Goodluck on your future passes.

The issue was not the EMS dumping the tune, but the one issue I set on before leaving the track. The 1/4 coil is toast, its the electrical connections and the base of the coil started to arc out to the mounting bolt. So I now have 2 replacement coils and the car should be at Cedar Falls the 26th for some more track duty. I will be working on the launch for the first few runs, then its off to break the record.

Just answered your question in the post above mine.

Nice, I'm looking forward to see that record getting broken this weekend.

I ran at Cedar Falls this weekend, It all came down to track prep, I knew what RPM I need to launch at to get the 60' and 1/2 shift where they need to be to get the 9 second pass. But the track had no prep, so it just spun with a little wheel hop. Then I tried lowering the launch RPM and tire pressure, I ended up with a 1.73 60', but it did not shift into 2nd, so it was a bad run.

My last pass of the day I upped the boost a hair, cooled the W/A down, lowered the tire pressure again and ran another low 10. 10.11@149mph, I was 2mph slower in the 1/8 vs my Rock falls run, so the traction in 1st/into 2nd was not there.

I looked over the logs and I could see the lack of traction, but I was happy to see my shifts averaged a .250 seconds, and I nailed the shift points with in 100rpm of 9500rpm on each run, my last run it got up to 9500rpm in 4th, so I may need to up the rev limiter a hair.

The day was cut short again, the radiator started to leak, so I cut it off to fight another day.

149mph, on E85, also the highest trap in the Galant VR4 that I know of. I plan to be at Rock falls on October 9th for the last time this year.

[awd-drifter]

haha. i missed the typO! apparently it is. I've looking around the internet/youtube and it seems that you have the fastest trap for a gvr4

[niterydr]

Good luck in October!!

John, have you looked at trying to setup the AEM traction control? With the trac prep issues, perhaps limiting the power in 1st and 2nd to the limit of the traction will help you fix the short time.

Let me know if you want help.

[Pushit2.0]

That will be next year, right now it has a ball/spring MBC.

Pending temps with the good track prep on the test and tune days at Rock I should be able to get the 60' down to the 1.6 it needs to be. The hand break helped a lot with getting the launch, I will also setup the 2 step and the no lift to shift, I looked over the logs and the engine likes to free rev when I shift, I see where I shift at 9500 but the motor keeps going. In the logs the motor got to 9950rpm between some of the shifts.

I thought they were going to do track prep at the house of hook, if I knew they were going to do no prep I would have waited and gone to rock falls for a test and tune. Next year on QTP tires I might have better luck with less track prep.

Any idea what would cause that?
