Like the title says, but i have the kelford st2 cams installed, but all else is stock.

And does anyone knows how high can i go with these cams?

 

No.

 

The problem isn't the cams, it is your valves and springs. At 8000 you could snap a spring and float a valve, especially with aftermarket cams having a higher lift and duration than stock cams. They are just more aggressive on the valvetrain than the stock cams, and that added with a higher rev could cause serious problems. Build the head if you plan to rev that high.

 

^+1 what he said, with higher cam you might snap even worse. Did you change your rev limiter or ?

 

dont most people switch switch valve springs/retainers when they do cams? I have always done Ti valve springs/retainers when I worked on Hondas but we were also talking about 9k + revlimiter

 

I'd be the most worried about your rodbolts revving that high on stock internals. Torque tends to snap rods on the stock internals, revs tend to loosen the rod bolts.

 

No for that i would build the head so as the engine internals. Like rods pistons etc. Also i would stay with the 2.ol engine set up. And you can rev it even higher.

 

thanx for the heads up guys

 

Gonna have to say a big negative ghostrider. No real reason to raise the limiter anyways unless you're running a bigger turbo. (In my opinion. Could be wrong.)

 

wut? Turbo really does not effect how high and engine can rev, its a bolt on piece. The main components of a high revving engine is the internals and being well balanced. Also if he has cams without a tune shame on him !

 

He probably mentioned that because the stock turbo is out of steam at high rpm so there is no point to rev that high.

 

Gotcha makes sense now

 

I have tuned an EVO X with upgraded springs and cams and she shifts at 8000 RPM. I wouldn't want to go much higher than that with the stock connecting rods.

 

I am not trying to be a jerk, but saying that you have done one thing doesn't mean its a good idea. The same logic could be applied to people that have jumped out of airplanes and lived without a parachute...just because it has been done doesn't make it a good idea.

8k on a stock turbo with cams/spings, maybe, but on a more powerful setup that isn't a great idea if you ask me.

Like I said, the rod bolts have let go on several people due to 8k rpm revs...so i would at a minimum do rod bolts if you plan to rev a little higher...but in my true opinion rod bolts are dumb and if you are going to that trouble you mind as well do drop ins.

 

Definately recommend against reving that high on stock internals. I was running over 600whp on a daily driven stock block and never wound her higher than 7300.....even now I count myself lucky that I never did any damage to the engine.
