My 4x4 cossie turbo has arrived and my adapter to fit my S2 should be here in 2 days or so, so i would like to know what max boost i can put thru it? Turbo is mint no play done 60k, engine also done 60k.

I am curious as how much boost my engine can handle it is a case of getting it set up (fueling etc) so it can handle whatever boost the turbo can handle till it blows?

The tuning limit is the detonation limit which can ONLY be found by live mapping !!

The physical limit will be engine strength, turbo efficiency and injector size/fuel pressure.

Stoo

Is it the standard ERST fuel set-up?

i used to run 22psi on my erst on standard injection mate

all thanks to mark shead's setting up
but i did lower the compression, shot peened the rods and crank
totally lightened and balanced from pully to and including clutch.
arp big end bolts, grs intercooler

its a standard engine, apart from chip, zorst, cam, filter,

Eagle cool 22psi, wonder how far down the road i would get if i asked SCC to set it to that

If you want to make it home in one peice I wouldn't go for anymore than 17/18 psi mate.

I reckon spike about 20 hold about 18

keithG666

mine spikes at 20 holds 18, 17, 16, 15, 14, 13, 12, 10......

but that was with the old wanky pace!!

should be peaking at apporx 21 / 22 and holding 18 with the new much BIGGGGGGGGEEERRR intercooler!!

but i won't run more than 18psi...... (as i have nos)

It's all to do with cylinder pressures and the correct a/f ratio. Obviously with stock c/r, you will be limited to the amount of boost you can run unless you lower this .

I would take it to someone who can det check it for you and set it safely using the correct equipment to find out where the limit is (det-cans etc).

oh cool cheers mike, thats wicked, as it explains it very well.

Keith it dont matter how much boost you got, when your nOZ blows your engine up

**read signature**

and its FACT that a VERY VERY VERY small % of NOS users blow their engines!! in fact, it can help cool the engine!!

the blown engines are usually down to either crap installations or just badly setup with too much NOS!!

GEEK!!!!!!!!

wiring..JUST the wiring

Gra

Max your mistake, Jim did the wiring, Keith did the install,

Well probably have to evacuate Santa pod

Jim Galbally

i havent touched it yet

which reminds me kieth, when you wanna get the wiring done? i SHOULD be free on saturday afternoon (im going to SCC in the AM providing my springs turn up in time). you pay for my petrol and buy me a maccyDs tho

CabrioTurbo

PMSL i reckon the ACT will be in tripple figures if your using a standard intercooler and lots of boost...
If your still on the standard cooler then judging by the rest of the spec this will be what limits you most.. IMO you wont want more than 13Psi

keithG666

how much is your petrol???

and yes, if you want to come down saturday....I'M FREEE!!

but i got to meet up with chip sometime next week to pick up the minimiser...can you still wire it all up without this at the moment?!?!?

Gra

no i meaant to say i will be using a cossie 2wd intercooler as well

Nitrous doesnt blow up engines, just like boost doesnt.

Its STUPIDITY that blows engines.

If people are going to play with things they should learn enough about them first, or get the help of someone who does.

Keith, you can wire it up without the minimiser and then alter the wiring later.

Gra

chip you should re word that
