like the car would surge up and down constantly...trying to find the ideal idle spot...it does all the time, and i have a T-Back w. no cat and my car is loud as hell even @ idle...w. it going up and down it gets annoying real quick..now the idle is a constant...just like stock except its lumpy...the rpm does drop and go up once in awhile but nothing u cant handle...

LMAO....

 

...I couldn't resist

 

How many 264 users are installing them "zero'd" without adj cam gears? I don't want to spend the extra $$$ on the gears nor do I have access to a local AWD dyno for tuning. Will I still see good gains just dropping them in?

If I can really get 20whp from the cams combined with a flash, TBE, 20psi and IC piping I will be thrilled!

 

I thin you can. I don't see a need for gears if your running 264's.

 

i have adjustable cam gears with my 264's but theyre but still set on 0/0. they are nice to look at though!

 

I have mine at the stock settings and had Al custom tune my car this past Sat. and what a difference it made. I drove my car all the way from KY to Chicago to get tuned and it was a totally different beast on the way home. Depending on your intake setup, you might want to think about getting some 660 injectors to. I have the HKS RS kit and I'm on the border line of running out of injector. I had to turn the boost down since I still had the stock ones.

 

How's the idle on the 264's and how your gas mileage with the cams. 264's seems the best for all around driving.

Upper IC pipes are not a limiting factor for you. I'm making ~350whp with the stock upper IC pipes.


There are cars running 11s on the stock airbox and filter. Contrary to what you may have heard, you may actually lose power by changing it.




No. You wouldn't run out of injector unless (a) you had a bigger turbo, or (b) your A/F is incorrectly tuned (much too rich).

 

Does anyone have sound clips of the idle on the EVO w/ 264's or 272's?

 

Is there much loss of bottom-end power or increased turbo lag with the 264s?

 

No, not at all when the ECU is properly tuned.

 

I made 31whp with cam gears on the OE cams, then got 12 more whp after adding the cams. The peak numbers don't tell the whole story, because I advanced the gears from -5/-5 to -3/-2, and picked up a nice amount in the midrange. Still, cam gears will do a lot more than cams by themselves, particularly from 5000rpm to fuel cut.

 

The idle was a little lumpy til Al fixed it. He has a idle fix reflash for guys with cams. It adles alot better, but you can somewhat tell I have them in there.

What would you consider a "much too rich" tune?

 

The stock injectors will support just about everything one can do with the factory turbo. So this begs the question, how specifically did you come to the conclusion that you are running out of injector?

 

What setings did you set the stock cams at for 31whp gain??-3/-2??Thats a huge gain.I might have to put these cam gears on.
