Ahh, I see what you guys are saying... I guess I looked at the graph too fast.

This weekend I am going to try and get a log, a full 1/4 miles type pass. (We don't have 1/4 miles here is SC (Charleston).. So, I usually go out to a road that is so little traveled. I really am wanting to see what a log like that looks like in my car.

 

And, what is going on with the wierd 1st gear RPM line at 6727 rpm?

I am trying to figure out what is going on there....

 

I assume it's the clutch slipping ...

 

I had the same experience. 116 was the best trap I could get in 4th gear bouncing of the rev limiter of 8000.
Now I have an Evo VIII 4th gear. Trapping 117 at around 7100.

ShamelessCookie - you can get at least 116 traps before you will need 5th.

 

I may be a puse but I don't spin the motor past 7600. I don't make power up there and once north of that you start to see cap studs let go.

 

whoah - i've never heard of that on an evo.

 

i trapped a higher 119 in 4th gear the same night i made my 11.8 pass at 116.5... Its possible even without the viii fourth gear

 

Wheelspin looks similar on a log as well. My last weekend in Roswell, saw logs like that in first every run.

 

Mine really starts to fall on its face at 8300. On the stock turbo it always pulled hard to 8K so thats where I would shift. On the street I have gotten away with 6* at 25psi at peak torque (lots of other variables probably allowed me to do that). Even with cams and a Green at the same boost I am running 0-1*.

Up top though is like what everyone else is saying 13-14* tops seems to be all the car wants on pump. On race gas I get a few more degrees but the car still seems to only like 17-18* maybe 19 on occasion.

How many lbs/min were you moving for those times?

 

 

shameless, what software are you using ?

 

I'm coding a web-based log reader that does dynamic graphs

other than that, I just use Excel

 

Oddly your tune and airflow look great but those times are pretty slow.

 

thats pretty cool... thanks man

 

My stock clutch is toast and my shift points were a bit high. I figure I can trap 110 with better shifting, which equates to low 12's on a good launch... but with a gross burning launch and sub-par shifting, I can only make 12.7 or 12.8 hehe
