Safe Boost

[Sir Lord Van Von Vader'ham]

Just after a rough idea on how much boost a standard RB30 with a 25 head can reliably take. Should mention that this car is only ever thrashed.

There are some ppl with big numbers in the dyno thread, but i dont know how long any of them have lasted.

Was hoping for around 1 bar and, yes, tuning is happing at the same time.

thanks in advance

P.S sorry, I did search. You try putting those words in and see how many pages you get

What turbo, what internals

[lachlanw]

with that info the only safe bet is none

[Sir Lord Van Von Vader'ham]

dont worry, sorry. looked in the rb30 tread/forum

btw, its just a freshned up, standard bottom end with a TO4z. what can i say, im a cheap 31 owner!

300rwkw to be safe. the tune is more important than any set boost/power tho. ask your tuner to keep it nice and conservative and use whatever boost needed to make decent power

[Adriano]

I dont know if i would consider stock rb30 pistons to be too safe at 300rwkw, plwnty have done it, but they tend to be people who constantly monitor their tunes

Boost doesn't mean anything.

It's power that kills engines.

As long as the engine isn't knocking (i.e. has a safe tune) the power limit (someone said 300rwkw) is what you need to factor in, boost has nothing to do with it.

hence why i said to keep it nice and conservative. theres always gonna be a chance of it dying from bad batches of fuel/dying fuel regs etc. but the same things can kill motors at standard power levels aswell (just not as quickly). aslong as you dont let knock go unchecked theres no reason it cant be reliable at 300rwkw, especially with the nice big exhaust side of a t04z

the biggest issue will be my driving. its a supersprints/drift hack . everything is checked anytime it goes anywhere.

the tune will be fairly juicy done by the boys at ESP, so im not worried at all there

if your going to be bashing limiter a lot it'd probably be worth getting a crank collar and ask the tuner to take out lots of timing just on or above limiter.
