GTRS n Full boost with Stock Cat

[starfriend]

Hi,

Running Revo GTRS but only at 14psi atm. Will it be dangerous to run the turbo at full boost with stock cat? i only have cat-back exhaust (magnaflow) and will most def be changing it asap. but in the meantime, will it be dangerous to run it at max boost?

Thanks,
Starfriend

i wouldn't, i suspect that is why my K04 died and have also heard stories of others having the same issue.

well, your basically going to SERIOUSLY heat shit up there... You can do it, but Id keep a big eye on EGTs

Even on the stock K03, REVO stage 2 (injector file), it is susposed to be detuned (lower boost/timing settings) if you don't have a test-pipe and Full exhaust. My local dealer said that its to prevent premature turbo failure due to too much back pressure.
That's on a K03...I def wouldn't suggest it on a GTRS.

I have the REVO BI file and an ER TP (AWE exhaust in shipping now ). Before the TP I could heat the stock cat up pretty good (I don't have logs), but the stock cat/turbo would visably be starting to glow red after a hard run. Now the turbo may show a little...but no where near as bad as before the Test pipe.

hmm, running my gtrs @ 0.7BAR (12psi ish i think) i only get eGT's of max 750 @ 3rd gear pulls.. only tried like two tho, to be sure at least i can drive the car meanwhile im locking for a local exhaust shop to get the cat and downpipe switched out. Thanks a lot all.

Ran mine on a stock cat and stock manifold up to 18 PSI for a while and it did just fine.
