Dyno Sheet:

Notes:

We have got alot of request and questions regarding what the stock turbo can do with a set of camshafts. Nothing was changed on the vehicle other than the camshafts and tuning. So here is the results.

We installed out AMR 272in / 272exh v1 Camshafts on a STOCK TURBO 2008 STi. We were very impressed with the results. The turbocharger is pretty much done with the camshafts. Boost hits 21psi and tapers hard to 14psi. The original tune boost tapered from 21psi to 16psi. The turbocharger does is not large enough to produce the air needed upstairs.

As you can see from the dyno sheet. Across the entire RPM band we picked up HP and TQ. Peak torque jumped from 390wtq to 420wtq. Peak horsepower increase by 20hp at 5200rpm but continued to gain and showed a 40hp increase at 5700rpm. No doubt with a larger turbocharger the gains will continue to grow and shine.

AFR: 10.8afr
Octane: Pump Gas (93 octane)

On a side note we will be installing our v1 272/272 camshafts on a 2008 STi equipped with our T60R to show you guys the gains with a larger turbo.

That's pretty impressive! Tons of torque out of that little turbo!

wow very impressive

EDIT: i definatly want to see these cams with a bigger turbo...the power and tq fall off fast up high...

Damon · 05-18-2009, 05:46 PM

to change out the cams, does the motor HAVE to be pulled? i can def see it'd be a much easier job with the motor out, but is it a must?

id prefer a cam of this nature over meth injection personally. i feel it'd be a safer alternative to similar power gains.

most people would...and i agree...but other would say meth is better because of the cooling abilities it have, but still i agree with u

Yes, the engine, unfortunately has to be pulled out in order to install the camshafts on the EJ series engines.
