With the advent of my new super high resolution Dyno Dynammics Dyno it was time to spend an hour moving the car gears around to see which gear settings yeidled the most power and best shaped power band

Car was a Buschur Racing Stage 3

HKS 272 / 272 cams

Here is the before and after one hour of cam adjustment

You can see that HKS out of the box are dialed in a very good balance

The adjustment basically just moved the power band up a bit higher in the rev range - taking a awahy a bit of TQ and giving some top end


The cam gears used AEM are nice and have 5 locking bolts - good stuff

wat is the cam setting before & after....

 

Sorry to bring this thread back from the dead but............

+1

I saw a thread about the 280 cams on a dyno and the cam gear settings played with on there and wonder if the same applies to the 272 cams!!!

 

hey Al, was the idle improved just a little bit with the special settings?

 

The idle might have been improved with the setting but for the most part 272's idle fine.

 

This image depicts two back-to-back runs with no change aside from moving a set of HKS 272 cams from -3/-3 (red) to -4/-1 (blue). The difference was noticeable from the driver's seat.

 

Al my question is...

will the EVO IX with cosworth cams gain anything by playing with the exhaust cam against the mivec timing? for example a +2 or a -2 cam timing on the exhaust cam will it generate more power or not? Have you tried something similar?

P.S. Still waiting for the parts to come... I will call you to do your magic tricks again soon... !!!

 

The effects at altitude seem to be more pronounced
