Safe EGT For RB Engines

[adam 32]

what sort of exhaust temps can the stock RB20 engine take? is there a temp you want to stay below?

or if the engine gets over a certain temp youll be causing engine damage?

thanks

I have taken my RB25DET up to 950°C and that was flat out. I don't know how long it can take it at that temp though. It certainly didn't hurt it I don't think.

I dont think it is much of an issue 1000 deg wouldnt be a big deal

urs would run cold with that big turbo and manifolds on it Adam

Mine gets to 700 at the mo

[adam 32]

yeh mines at 700 on full load

how would the different manifold cool it down?

[macka]

Bigger pipes, bigger turbo housing and wheels = less dense air = cooler zorst temps

u on icq?

I probably should mention that 950° is at full throttle for like a minute straight. That is hardly normal driving. It's between 650° and 800° for normal usage.

As per usual, the 950° was done on a private road

[adam 32]

well i nailed it on my favourite road today and only got up to 600....

i think im just stressing!!

so theres no real temp which if you go over then your ugnah do internal engine damage

900-950 is a safe level i have heard.

the lower the better

Depends where you have your EGT probe mounted too.

Sounds like you have it on your dump pipe.

the temps u all state are quite safe but over 1400,1500,1600 id be looking at some sort of support bracket for turbo/s as manifolds have a tendency to sag or fall off under high temps...
