I'm upgrading to gsc r2's and kiggly beehives and the r2's are supposed to build power to 8500, but I've been getting mixed opinions on what I should rev to. My turbo is a custom apexi it's equilivant to a 3586r with a 1.06ar hotside. Some say 8k others say 8.5k is fine. Whats your guys opinions thanks again as always!

 

8k on the 100mm crank.

 

What the R/S ratio on the 2.4's again? isn't it like 1.56 or something like that?

 

Is this a rev limit you are going to bang on the street regularly or just at the track? I go over 9k at the track, but drive like a grandpa in the street

 

Yea it's a summer car, so it will see a good bit of street usage something to do some damage to the local v8s lol

 

yeah 8k is a good number, even 8.5k but ideally 8k

 

I guess alot will be dependent on where my turbo starts to fall off no sense spinning it if it is falling out of range. For street use anyways

 

No, it's really more along the lines of piston speed is high on a 100mm crank, and they make a lot of extra harmonics. Regularly revving it past 8k isn't ideal for longevity. Sure, some guys do it at the strip in their drag cars, but that's not nearly the same as holding 3rd to 9k in between every corner of a twisty road, or at an autocross. Or even more punishing, at a track day.

 

I'll probably stick to 8k then it's going to be a. Summer street car with some strip time here and there.

 

This is great advice.

Even with a long rod 2.4L you don't want to constantly explore the outer limits of it's rev range.
