any ideas what power my EP91 will make??

[babu_rashu]

im going to book my car in on a Dynapack for a power run any ideas wot sort of power do u think il b looking at with this spec:-
forged with wiseco 74.5mm piston,TD04L turbo,WEPR extrnl wstgate mani,running 1.2 bar of boost,full straight 2.5" exhaust system, relocated air filter, EMB,warlbro,460cc injector, HDI FMIC, etc
oh on more info the octen is 91...

 

[Mark-ep91]

230-240 bhp

91 octane sucks i thought 99 was bad

Hard to say but on an EMB, id reckon 230bhp but under 250bhp at 1.2bar.

 

[babu_rashu]

octane rates sucks man.. nothing to do...any advice ???

 

[babu_rashu]

dyno result is 205 bhp @15 psi of boost...afr 10.5

 

[Mark-ep91]

is that at the wheels or flywheel?

 

[Iain@CRD]

Fly i would suspect at that octane rate.

@ flywheel mate

hi mate the reason why ur power is down because ur afr is at 10.5, far too rich its just chocking the engine with fuel, ideal afr should be at 11.5 if you are running big turbo and big power, full build ect. (boost)
11.5 afr should help cool the pistons and engine down.
12.1 afr should be ideal for stock turbos or light mods as you can't run much boost anyway.

have you got your graphs so maybe we can see where you should maybe lean it out ?

 

[babu_rashu]

hi dynoray.. thanx for da info bro...added my graphs...oh rep added

 

[dynoRay]

hi mate that fine, but ideally need the afr readings to read the peaks throughout the rev range

 

[babu_rashu]

oo ok... i will post it very soon...

assuming them figures are at the wheels dude thats about 200bhp is it not ?? good for your octane rating :rockon:
