Hey all, we had an opportunity to visit TurboTrix last weekend and dyno one of the 280 cammed Evos. The 280's had no detrimental effect on the powerband, in fact they provided for nice, strong pulls.

what other mods did you have?

 

Generic bolts-ons; turboback exhaust, profec b ebc; nothing crazy besides the 280's.

 

What were the numbers before the 280's.

 

pump gas?

 

i was thinking about getting 272's, but if the 280's run good i might get those. Is the idle about the same as the 272's? And what is the gain on the 280's compared to the 272's? Do u lose any tq? Or does it just have same tq and more top end then the 272's?

 

How much more hp do you think you can get with the 280's vs the 272's? Would you say 280's would be fine on a stock turbo?

 

bump for some answers

 

Any stalling /idle problems using the reflashed ecu ?????

What were the cam gears set at ????

 

We originally set the cams for -3; however max power peaked at 0. So, from that, we discovered that Cam gears were not all that necessary, concluding that the 280s would have worked okay with stock gears.

There were no stalling or idling problems - ever.

Unfortunately no concrete #'s on the 272 vs 280. However, I believe that Buschur has dynoed them @ 30 or so wheel HP.

The main point we wanted to establish is that 280's work just fine.

 

Good info...THX

 

hmm, its going to be hard to decide what to get. the 272's or the 280's

 

it is my understanding that the 280's yield the most power ONLY with a large turbo since the stock turbo runs out of steam when even adding the 264's. correct me if i'm wrong...

 

I have 272's, here is my sheet



Same exact Dyno.

I think my powerband is fatter, more power faster.

What mods do you have on your car?
