Results Of My Gtr Tune

Its a tomei stroker isn't it?

[Beer Baron]

stock cams and afms is pretty good going for that kind of power. I was assuming maybe nismo afms mounted to the stock airbox, with maybe some 272/10mm or thereabouts cams in there

Who told you that ? I think i should know whats in this engine , i helped Mick assemble it and put it in the car !

Mik actually ended up sticking with the 2.6.

I think money is a big factor in a build like this.

Actually Mik, i made 305awkw on crd's dyno, but at something like 19/19.5 psi, which i didnt think to be safe on a stock car. And we made 315rwkw on bel's dyno with what i reckon to be another 15-20rwkw to gain (hopefully).

This car sounds absolutely awesome. Particularly on the dyno when it starts spooling. The power curve picks up ridiculously after about 4-4500 rpm

ok fair enough, thanks for answering my question Tommy

Sorry guys I was wrong about the crank

Nope Nismo AFMs and the stock airbox. I don't think it would have this much mid range with wild cams like that.

[Beer Baron]

aha! I guessed the nismo afms ok, then cams maybe something a little milder, like 260 deg 9.15mm all 'round? am i getting warm?

Just another interesting point. The guy we use to do cranks checked my new jap crank fro starightness befiore I used it. He said it is the straightest new crank he has ever seen out of the box. He said that most yankee cranks ( mostly v8s) usuallly have a couple of thou runout.

It's a forged semi counter 73.7mm Jap crank of unknown origin.

are you going to tell us how much boost was used for the run?

I don't think he wants to tell the truth as to what specs or boost its running

The thread is just so we can all say WOW look at your power and how your turbos aren't to laggy when its probably not even RB26 stroke anymore I say close the thread its a bunch of crap

[Shibby]

wait wait I forgot its got a stock airbox aswell oh WOW your amazing, forged crank and what ever else but lets just talk about the airbox so it makes you look even better

well you did say in the 3 litre thread

"The guy we use to do cranks checked my new jap crank fro starightness befiore I used it. He said it is the straightest new crank he has ever seen out of the box."

well what did it say on the box....my bet is it would have came in the same box as the rods and the pistons.....im with bu5ter on this one....why the smoke and mirrors?

Whatever mate...When did I talk about the airbox??

And I don't answer to capitals.

For anyone else that want to know...boost on that run was 1.45bar.

haha...there is nothing on the box...do you want to see it? Your welcome to drive down to sydney and take a look.

And the pistons and rods definately came in a seperate box.

[BU5TER]

Maybe its a china crank

[SLY33]

so whats the deal here? Mik, people obviously think your are telling furfies, why would you want to post your results then lose credibilty for appearing like your not telling it as it is?

My opinion is that the setup is making full boost far shy of 5000rpm, which would be some feat given other 2.6's with GTRS's make full boost (1.3bar for eg) at at least 5100, 5200.

id love SK to drop his views, as once he has a look at the graphs and does his maths, all will be revealed!!

dont get me wrong, not trying to bag your credibility, just would like to see all the facts.

theres nothing wrong with the stock airbox. I run one in mine too, but im making about 60rwkw less than Mik at the moment

My old set up (bog stock, tired 86mm bore engine) and GTRS turbines made 1.4 kgcm^2 boost at about 4750RPM.
