Ok I am getting ready to play with cam gear timing because my last trip to the dyno was depressing to say the least(360whp) so let me list some basic mods I have,20g-8,HKS 280's,1000cc inj,built lower end,built ported head, ported everything else, ams fmic, hard pipes blah blah, I had ams tune it on e-85. I know there is way more left in the car so I am trying to find it so any input is going to be helpful.

Has anyone found any power with cam gear timing on similar set up's? Also I will be spraying a 75 shot or so in the near future. Cam gear timing is where my knowledge starts to taper off so please explain if you can. I just need to know where to start and what the pros and cons will be.

Also before anyone asks I do not have any boost leaks.

 

anyone? someone has to know something.

 

This test was focused on 272s but i'm sure it will still be valuable info in your case. Here's the link https://www.evolutionm.net/forums/sh...d.php?t=100413

 

Tuned an EVO IX tonight on AEM EMS. The setup was not similar to your's but I was able to gain an additional 35whp - 38whp midrange and stayed exactly the same uptop. Owner was impressed as he didnt think we would see any gains
