just what the title says. 272's or 280's with AEM. I dont' know how to start a poll.....so if anyone wants to help me out....i'd appreciate it.

And Idle is a factor. With 272s on my last car with AEM...it idle'd like stock....i dont' mind if it's a little lumpy but i dont' want it to sound like crap.

anyone with 280's with AEM feel free to comment

thanks

 

Are you getting a bigger turbo ??

 

as surprising as it may seem, ive seen the 280's give a nice top end boost in hp even with the stock turbo.i have 264/272 setup and i love it, great tq/hp combo. if you're getting a big turbo go with 280's, if not i'd stick with 272's. Do a search, there are dyno graphs of both setups available.

 

i have my 50 trim sitting in my garage....with that turbo on my last car with 272s it made 429 on pump...

 

it's either gonna be idle or power that's sacrificed when running the big cams. i say try a combo no one has done yet. run a 272intake/280exhaust. with the AEM, you can fix most of the idle. with a good tuner, ALL of it.

 

272's should be fine for 500hp. 280's are pretty aggressive.

 

272i/264e with stock turbo. 272s with upgraded turbo

 

272

 

no matter how you look at it, more duration means a rougher idle..
