How much boost?


Recommended Posts

How much can I increase my boost too before having to make modifications to the turbo?

You might wana keep it around 11-12, for more reasons than just the turbo's life.

To avoid detonation, and keep the turbo efficient most people tend to keep it round there. With correct tuning you can get alot of power out of them on low boost with a SAFC or similar.

agreed.

i think the general consensus is that @ 14psi you are pushing not only the flow capacity of the turbo, but also the life of the exhaust wheel

people generally run around 12psi feeling that this offers the best power for turbo reliability

(also, a search would yield quite a few threads on this matter)

Waz.

you blew the turbo 3 times on the standard set up? Im thinking your boostguage was faulty and you were running significantly more than that...

either that or there was another inherant problem that caused it and wasn't being addressed...

no my boostguage was perfect ... my car was standerd ... only for the KSROM chip

which is set up for 12 psi ( i dont have a boost control ) .. and 8000 rev ( they did it is japan) and some fuel and ignition remaping ...

and 3.5 inch exust ..

no cat no nothing .. but the muffler at the end .. thats why my turbo exust wheel spen all the way out of the exust .. lool ... :cheers:

maybe from the way i was driving ... lol .. drifting all the time .. and the rev was always high ... above 3500 .. :rofl:

any way ... its over ... i have my r34 now ... never reach 3000 RPM :jk: lol

some pic of the turbo ... with something missin :)

lol good effort, im not sure how the hell you managed to kill 3 on standard boost but thats pretty special dude lol

Take it easy on the 34, those turbos cost a wee bit more. I guess you could buy in bulk? lol

Cheers
