-7/9s Or -5s Garretts

[Piggaz]

It's only 8.4:1 comp ratio isn't it?

[Ants]

yep it sure is.

[wolverine]

More boost + good tuning = still safe

I know Paul.....I know. I'm just conservative and want to have an engine tuned to last as well (I will certainly not push my advance spec beyond 25psi). Your car is insane and would of loved to have a 2.8ltr with similar mods to yours

Keen to see those graphs though.

Look my dyno sheet is in the dyno section running -5

[KING87]

I'm running 25 psi on -5's on a stock 2.6 and it's good to drive on the street. How long it will last is the old piece of string rule I guess. On a built motor push it as hard as you can I say

[Ants]

dude 25psi on stock 2.6 = BOOM!!!

[KING87]

I'm confident it will hold up for a while and so is the tuner. Running e85 so it helps alot.

What power figure you making?

[Marko R1]

I've popped 2 bottom ends on 23psi...ringland both times. It will let go, inevitable

[Ants]

I'm gonna guess - 337rwkw

Built or standard?

[KING87]

Yeah I realise it will let go at some point but why not lean on it a little see how long it holds up.

Both stock paul. Both tired/pushed engines

That would be a safe-ish figure for a stock RB26.

But personally, I wouldn't push anything past 300 rwkW's on a stock RB26.

Fark!

At the rears?

[KING87]

Nah 4WD dyno

[(OO)SKYLINE(OO)]

Nah 4WD dyno

I see!

Still a big power figure!

Under 300kw on a stock engine would be a good buffer. I was only running 325awkw when it let go. But then again I had a 89 gtr so the engine had a long life.

understatement......I have deep reservations about that engine's longevity at that power / boost level ......I sure as hell would not want to be in the car when she goes BANG!
