0.86 Turbine housing : 571hp with 1.06 housing

Interesting, I have no problems with EGT even with GT30R and 1.9 bar to 7000...
What kind of exhaust manifold/exhaust?

What timing do you have at redline? Can you run more?

Tubular T3 with 3" exhaust... ignition at redline 25.5 deg...



...with water/meth 625cc EGT 30-40 deg lower

[prj]

That is a lot of timing...
Odd that you have EGT problems. Try to measure the backpressure perhaps...
EGT issues can also be due to cam setup, exhaust manifold, matching machining between head and EM, and so on.

What diameter runners are you using on the EM?

EDIT:
Just read that you have a 3" exhaust. That is too small for sure.
You should have 3.5" at this power level from turbo.

measuring of exhaust backpressure before turbine will be the next step after hibernation

exhaust backpressure of exhaust after turbine is up to 400mbar - so we throw the cats out - no effect in temperature.. so they are back in to keep the car legal...

cam setup is OEM timing 7a in and out...

diameter?? I dont know: http://www.furans.se/buystuff.htm

0.4 bar after turbo is quite a bit of pressure IMO.
Was it less without cats?

never measured because of no effect to temp...

Maybe the restriction are not the cats...
But generally 3" is until 500hp or so, after that you should have a bigger exhaust...

we will see in a few months...

My system is full direct 3" with screamer pipe,what should I see in fifth gear 6000 rpm 2.0 bar?

Maybe you would also like someone to read your palms and tell you the exact date of your death or similar?

what?

ill check tomorrow if is not wet

sounds interesting cause no "Autobahn" in Spain...

you have to go through gear 3 4 and 5 full throttle to get a result...

sometimes we needed 10 sec. in 6th gear full throttle to get 1000°C EGT

the car has 6 speed,so 6000Rpm/5th gear will not be "too" much

i know some nice straights very near to my home....with dual road for the same way

Ok,3,4,5 WOT... 98 RON fuel without water/meth injection

...1000 degrees EGT, whooo !

[mushasho!]

Which tubular t3 manifold is receiving such abuse?

What AFR were you running?
