Just went to a visit at Jian Hang, mechanic says I need to completely change my exhaust system from scratch as the one I'm currently using is for 850 Stock .
Person is asking me if I should use bigger pipe or 2" is enough . 2" just normal stock turbo exhaust system. Not sure about this eh.
Should I change to a higher performance blow off valve or keep it stock ? What about K&N high performance drop in panel air filter ? Should I change to that as well ?
The stocks 850 exhaust size is bottlenecking the exhaust flow of u convert to a turbo engine. 2" size piping will be just rite for OTR / daily used.
Stocks blow off valve is adequate already for the stock turbo..there's not much increament in term of power gain for aftermarket blowoff valve. Just increase the efficiency a bit on releasing unused air when the throttle closed to prevent backflow to the turbo.
Changing to aftermarket air filter closed / open pod does give some minor power gain but your fuel consumption will increase a bit with all that extra air coming in into the intake / engine.
wah looks like another overhaul and mods coming....
the engine was fully overhauled before this race..maybe something went wrong when assembling the engine ...need to do compression leak test to find out where got bocor one
But I sent it to a shop. Did top overhaul. There was some head skimming done according to the receipt hahah. Is it that bad to skim the head? Or maybe he lied and didnt really skim? Idk.
But now all is good and smooth. Hopefully no more overheating.
BTW, where can I get a complete samco hose kit? Not just for the radiator but for all hose. Is it possible?
Thanks!
Rev performance at sunway so sell L5 samco radiator hose kit
