67's pretty big surely they would surge?

500kw sounds big though

[mr skidz]

Luke at race pace said he'd tried GTX2860's on a turbo combo test car and said they'd surged a bit and made 390kw

[sneakey pete]

Any idea what front housings he used?

[mr skidz]

I mentioned GTX2860's with oem .42 comp covers machined out with -5 rear housing and he said yeah he tried that, might be worth giving him a call yourself speak to Luke and ask him to confirm the supporting mods maybe.

I thought that would at least make 420.

My motor is being assembled very soon and I'm currently on the dash 9 bandwagon at the moment until I change my mind again lol

Well if Luke tried it and failed... Takes more than 20psi get the numbers.

Isn't that exactly what Daz used? I see he has given up on twins though...

[sneakey pete]

Well, that's not very good then.

Guess i can throw the standard comp covers back on if it doesn't work out...

[jangles]

I thought everyone knew the gtx turbos don't come to life until 25psi?

[burn4005]

Yea the compressor map goes to the moon pressure ratio wise compared to the normal gt wheel.

[mr skidz]

Who said anything about 20psi?

Who knows what he ran them at

[mr skidz]

Don't write them off just yet.

Unless someone sees the boost /set up, comparison graph we're all just pissing in the wind.

Lots of people saying that but my GTX2867 is fine at 19psi and drastically out performed the GT2871

I haven't seen results from GTX2867's got a dyno plot somewhere?

[Leroy Peterson]

Not a good one, just with a huge exhaust leak. Plenty of SR20 GTX graphs around though

Small single application doesn't apply.

Although they still wake up at higher boost, whether they make more on the same boost or not.

Gtx2867s will do 500rwks and above on a dyno dynamics dyno with excellent response with the right set up

Hi Daz,

have you got a dyno graph of the GTX2867s?

[GTRsean]

On a 2.6 you definitely need the right setup/method to be responsive

Daz has the right ingredients and method heheh!

By the way Daz I wasn't trying to be a smart arse I had good results from GTX2860's with a stroker setup, stock cams and BP98, but went shit when I put in cams and got another tuner to tune the setup when I headed north...

[Daz]

A good tuner is vital for a good result, I've wasted plenty of time and money on poor tuners

My car is on e85 which helps.

Ill put a dyno result once car is fully tuned unless I go single
