They are outdated, and expensive to fix if they Kaput.

Needs more Cowbell

1.7l AR owners what are you RPMs when you are shifting at the track? When pushing around 20~.

My dyno sheets are not a good graph to see peak power and I dont know where to shift to at the track.

Im not an AR owner but I wait until it screams before I shift.

I shift at 6000. It pulls good to the 6200 rpm rev limiter, but it's hard to shift over 6000 and not hit the limiter.

Despite what Dalke says, I think it would pull fine to 6500 rpm and all I've really got is that 208/.509 Crane cam with stiffer valve springs.

Well my dynos were 5800rpms Dynos and HP was still climbing so I want to guess that peak HP was around 6100-6200rpms. I was shifting at 5800-6000rpms according to the Data logs last weekend. But the higher I shift the more trouble I have getting into the gears. I suspect that I should be shifting at 6500 RPMs to get the most. But want to hear what others are doing with a AR 1.7l and a cam between 218 230 duration.

I try to shift at 6300.

I shift at 7500 RPM.

I believe a lot of people are leaving a decent amount of ET on the table trying to race their cars like diesels.

Solid lifter cams help in that department dude

[CMac89]

Yes, they do. Along with other things.

I can play this game.

I don't shift until she is done screaming.

[XxSlowpokexX]

Me shifting is what makes her scream.....

Has anyone gone from an m90 to an AR and changed there shift points?

I'll experiment with that next spring. I was shifting at the shootout with the M90 at 5000-5200.

Most people are limited with shift points by their valvetrain moreso than blower or cam.
