CT26 power

[SoarerTT]

hey guys my mate just bought a MA70 with a 7m turbo in it and he was asking how much power is a ct26 able to put out at the wheels stock and whats the max safe boost to be running

[Yian]

11psi made 152rwkw. Any higher than that, it hits 'boost' cut (i.e. maxes out the AFM). As for safe, I got no idea. It was only put on 11psi for the dyno run.

Ceramic wheel MR2 ct26. I've run 1.2BAR 16-17Psi but blew the engine The turbo is still fine it though the motor lasted 2 months a compltely stock 3SGTE.

[chris davey]

what exactly "blew" in the engine?

Doesn't sound like that much boost to be blowing engines.

[sw20r]

high milage motor (115,000kms) with some sort of oil being burnt somewhere as it needed 2L a month filled up the rods went and bearings too

my 7m stock ct26 wouldnt flow anymore air then 270 rwhp at 8-10 psi

[Classique71]

Running a steel wheel Ct26 ( group A gt4 spec ) on my 3sgte - stock as a rock - 220 thousand on the dial

At 15 PSI , its happily punching out 170 KW thru all wheels ..

At a rough estimate thats about 230 KW at the flywheel at maximum noise

Still going to try squeezing another 2 - 3 PSI out of her before it retires before upgrading to a Garret

7mgte ct26 is very different from the sw20/st185 one

[Classique71]

yups - if anything - its better

[Mr Revhead]

yes it certainly is

Is the supra ct26 a twin entry aswell as the 2nd Gen 3sgte?

in my car (st185) with a 220000km engine mine is good for 14-15psi and 140kw atw.

The only mod to the motor is a 1mm steel head gasket, this was only needed cause my boost controller fubar'd a year back and it spiked to over 20psi and blew the OEM HG.

since the gasket was done almost 6months ago it hasnt lost any oil or coolant and doesnt miss a beat.
(i service my car religiously though)

I had a steel wheel 7MGTE turbo on my 3T GTE. It managed a best of 193rwkw. I figure that is about 230 engine kilowatts.

[RA65 Sleeka]

A MA61 Running a 7m-gte with a stock ct26 at 1 bar made 225rwkw.

i'm running a 7mgte one in mine,,, dunno the exact specs on it, but it was rebuilt with a steel wheel and said to be "hi-flowed"..
compared to the old stock turbo its done wonders. i'm still running stock boost on it,
i'm happy with how it is at the moment so i havent really rushed to get a boost controller.
though what i am waiting for is the wolf3d. and once i put that in i will set it to about 15 for a daily driver.

No. I believe that it is single entry (at least the ones that I have seen are).
