it's difficult to hit 300 on the greddy, so you usually don't need to bother getting larger injectors.

there is much more to detonation than psi /timing and a/f ratios. those are very important no doubt--just dont forget all the other things--and as everyone has been saying there is no safe psi of boost.

/\ true but past a certain point with the Greddy does seem to be problematic so staying under 9psi will avoid a lot of that

JIN13

ok so greddy kit max boost would be 9 psi what is the max a stock rx8 can take with good tune and biger turbo and injectors

FLOW NOT BOOST FLOW NOT BOOST.....

Now write it down 100 times....

we're going to assume the car is properly tuned.



assuming you're using a properly sized turbo, you should be able to hit 350 whp without much problem. Several have gone to 400, but I personally won't venture that far because of what I precieve as longevity issues.

no no wha is the max boost of flow (for kane) that tha motor can handle stock

Fixed - and really good question... I don't think anyone knows yet for sure.

JIN13

thank you Kane that's what i was trying to say...

Here is a real brain teaser...

Will it be the ports that get overwhelmed? Will it be the Dowel Pins / E-shaft / rotor / housing / spark plug threads... etc.

Force moves in all directions - at what point does the FORCE of the ignition event (low order explosion) overwhelm the motor? At what FLOW does the motor cease to be able to draw any more air in; or push it out? What is the next weak link? - Seals?

No one really knows... that is half the fun!

JIN13

i guess we'll just have to wait till it happens to someone, hopefully never

It's an open question whether or not it's possible to get 100k+ miles out of a turbocharged Renesis making >= 300WHP; even if it is tuned to perfection.

Pushing the boost up is asking for trouble, IMHO.

Either way, expect to need a new engine long before 100k miles.

For what component?

Take your pick.

I choose.... Seat Belt Braket.

At 48 lb/min the seat belt will fail....

^ true statement- dont ask how i know

MazdaManiac

Exactly.
Though, I have heard that the glovebox latch is prone to failure at the same point.

how about the door handle?

Driver? Do your eyeballs explode at that speed?

no but there is a real danger if your female companion is wearing a thong .

Well, you shouldn't be towing a skateboarder at those power levels, anyway!

Only in the morning.

That is why I keep emergency services on speed dial.
You haven't lived until you see an EMT use the "Jaws of Life" on a deeply embedded thong.
