Hi all what is the max RW KWs i can get out of my 4liter without putting noz on it. Is 260-270 just a drem i have or can i get that ? And what are you guys getting at your RWs

260-270 RWKWs is quite achievable without nitrous... But forget about naturally aspirated, forced induction is the only way to achieve these sorts of power figures.

Be prepared to spend A LOT of both time and money.....

ok if i have 120/130 rwkw how much do i have at the flywheel?

YOOT · 09-26-2002, 17:17

About 185kw at the flywheel.

What have you done to you rcar, I am interested in about 130 rwkw.

Try a T04S turbo (12-25 psi), polished and peened rods with H/D bolts, lowered pistons, balanced crank. Another 6 fuel injectors and rail (w/- computer controller), exhaust and inlet mods, front mounted intercooler = 250-300 RW kW. Also need ignition amplifier. Has been done on an ED XR6.

Cheers

And alot more has been acheived in a el falcon it runs 10s

I just read on fullboost that a turbo charged 4.0ltr EF ran a 10.36 on the weekend. Damn thats quick!

i would say get away from the turbos and go 4 superchargers they r much more efficiant i got a qoute from capa for an ef kit that runs 9psi for 6000 grand pluss fitting which the guy said puts out 240rw kw! im a bit sus on that figure i reakon it would be 240 flywheel! but thats still a big improvment then u can always put a cooler on it and work the engine a bit more i reakon u could achive 300 rw kw with a bit of planning!

Thats what i want to do anyway! but mums ef when she trades it in and then i will have bout 12 to spend on it which would have to include suspension stereo and rims! then hopefully have enough 4 a full rebuild, intercooler and supercharger! which will all be fitted for free so i am hoping i have enough and that i can convince the parents to sell me the car!

Wrong, Superchargers are less efficient than turbos.

Turbos are spun using exhuast gases, which is free power, superchargers are spun by the engine, which uses valuable engine power.

With a decent quality setup running at the same PSi, a turbo will ALWAYS make more power than a supercharger.

And the Capa 9Psi kit for the Falcon is 240Kw at the engine, and the price is for the kit, does not include installation.

yes i no that and superchargers are more effiacant no matter what you say i have talked to alot of people about it and even turbo guys agree that superchargers are more efficiant!
