GT Motoring I believe was running a stock AP2 motor on the track up to 9k and it didn't last more than a season.

 

I think its when these engines have been majorly mishifted like 10,000+ and then you beat on them something lets go
Just get the valves checked out and keep checking it should be fine with whatever retainers

Realy is there a situation in an auto-x you need to run an ap2 to 9k because you are caught between 2nd/3rd that bad?
i think that would be an unlucky course that day

 

Almost every national tour.

 

I can't speak for any of the big events because I have yet to attend one but happens a lot at our local events here in N.J. We run at Metlife Stadium's HUGE 1,000,000(I believe that's how big it is, don't quote me on this) sq ft parking lot and the courses tend to have long open stretches where an AP2 "should" be upshifted to 3rd instead of riding the limiter in 2nd.

 

Yeah, when I was running my AP2 with flashpro, I had my limiter set at 8800 and I hit redline in 2nd all the time including Nationals in 2010.

 

Ditto @ 8500. Blytheville and Nashville this year. I am just getting a handle on driving and once I really figure out how to keep more of my speed in corners it is going to be more problematic.

 

AP2 folks, how long do you feel comfortable keeping it pegged in 2nd?

 

I can't say for sure in STr trim but I know on my previous 04 when I ran against collett in ft Myers at the national tour we had it pegged for a full 20-25 seconds

 

If you have it pegged for that long, your just lossing time. I ran an event last season where at 2 different spots I would hit the limiter for at least 7 hits(bah,bah,bah,bah,bah,bah,bah). During fun runs later that afternoon I decided to shift to 3rd and gained over half a second over my fastest run.


Ap2, tuned w/ FP and redline set to 8500.

 

It seems to me, if you're sitting on the rev limiter like some people are saying, you really should be shifting to 3rd. I'll shift if I'm sitting on the limiter for more than a 3 seconds or so.

I'm not reflashed, so I can't say for sure, but it seems like with a lowered VTEC engagement and more low end torque, you'd be better off short shifting third slightly than banging on the rev limiter for more than a few seconds.
