Performance Camshafts

i thought few guys at ah wah setup till 1.8 bar safely. but not really sure internal stock or not..

 

[stutzedward]

1.5 bar is safe level. U can boost to even 2 bar but briefly only. If you keep at that level for long, engine will kong.

 

[4gbanger]

2 bar is already wayy to high for internal stock..

 

[stutzedward]

I've seen stock internal reaching 2 bar.

Actually 1.5 is considered high for us but must use bigger turbo. Stock turbo is no point reaching above 1.2. Anything higher won't gain much fr td04.

Original only 0.6 bar la.

my point of view, 2 bar of boost is not practical for daily use.. only drag car set that high. even most race car ( in my experience, kancil turbo) set boost below 2 bar to maintain engine endurance during race..

anyone know how to send our stock airtrek camshaft for engineering to get higher profile n lift? i know matspeed can do it.. any idea?

 

[stutzedward]

High profile to low can do but low to high, add steel and re-machine it?

 

[4gbanger]

yup. i dont know for sure how they do it. but basically it may need to be welded back and re-grind the profile i think.. and i heard the charges are quite high.. rm 1k++

 

[stutzedward]

I see. I'll stick to original used high cams. Hehhee.

no, they just remove more material on the lower area (valve close)...then adjust tappet to compensate...

 

[4gbanger]

I see. I'll stick to original used high cams. Hehhee.

but if we compare the price with aftermarket camshaft is more expensive bro.. thats why i'm wonder is it okay to do or not..
