Performance Camshafts

[stutzedward]

Most of us who chg cams will use evo stock cams. I'm asking if anyone else use cams like hks or tomei in their Airtrek.

i know one guy in this forum uses tomei poncam with TD04..

 

[stutzedward]

I see... I heard with the right cams, adv timing and tuning with stock evo mods, we can get 300whp even not using 2.4L kit. So that's why it interests me. Ya'know, wanting that 30whp more. Hahaha..

increase your boost to 1.8 bar sure 300 whp one mah..

only if ur engine can tahan.high mileage can't go tat high unless rebuild with forged parts.

 

[4gbanger]

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...
