changing cam

[benjaminn78]

Hi guys,

i plan to change the cam from 264 to 288 with 9.2 lift, anyone using 288 cam? mind to share the experience? can piggyback support 288? i just using e-mange...

264 tara cukup ka ben?

ben with higher lift and duration of cam u need a higher compression of piston to cope with it oh...dun forgot to mod ya...and dyno out and make 4ag proud....our hope on u d ben....haha

ya..will try it out...and found out AUS standalone ECU adaptronic...less than 4K...good to have try...anyone can share their 288 experience?

Ben, don't mind if i ask. With a standard ECU running 264, does your rev goes beyond 8k and still going?

 

[benjaminn78]

BT rev cut is around 8.2k if not mistaken..so no matter high cam or standard ecu..can go beyond 8k.

cooool... but 1 word FOC you. Piggy back will not fulfill your high cam, and most important is check to fuel pressure, if not enough add in fuel regulator. It will slightly help.

I personally done upgrade to 272 hi cam only. But end up engine blow. reason is fuel not enough and A/F showed lean. Higher compression piston will only more early to blow up only. A decent ECU management is much important.

common... can anyone please help me out here.... http://www.zerotohundred.com/newforums/toyota/295970-seriously-need-help.html

the cause of ur engine blow is engine mapping tak chun...as ur cam duration get higher and ur valve overlap get longer. u need to a higher compression piston to compress the intake air ...it is hard for me to explain to u ....

as ur fuel lean out the combustion chamber get dry and heat up easily...so u need to add more fuel and slightly over rich at 8-9 k rpm to protect ur engine from blow..u won't care much bout petrol when u decide go full throttle rite....
