Gtx2867r Dynos

[keychain12]

I myself have a Gtx2867r and was hoping to see others dyno's and mods list (I'm currently running into issues with my CP-e catted downpipe flowing passed 360+ hp)



My most recent dyno with comparisons from last time:

Don't think it has anything to do with the stock intake and exhaust manifolds?

You know, it could. A local guy had the same mods with a VCTS delete manifold and a tubular exhaust manifold and he made 420hp lol. So something is choking me up

[Kor3y101]

Your sig says you have a 3" HTP intake? So do you have a stocker or HTP?

The guy above was referring to intake manifold and exhaust manifold I believe.

I have a HTP 3" full inlet and intake, but stock intake manifold w/ VCTS.

Ahh of course. My derp has preceded me.

It would be better if you could post a WOT log. That should tell us more about what is limiting your hp

Looking at things like your boost, AFRs, etc can tell a lot about your tune

Tell ya what. I'll get some logs and throw them up.

But for now, I'm just looking at others to see how they are doing on this same turbo

I should note I'm up in WA and we have very limited sources of e85. So WMI is really the only alternative fueling options for most.

21-22psi on dyno
HTP 3in
stock EM
Stock Midpipe
3inch axle back w/o muffler
Meth 30/70 mix 500cc

Yes, but you are on Meth. I could make the same if not more power than I am now on 93 and meth.

That was my concoction. Actually that was a GTX3067. nevermind. Same compressor side as the GTX2867 just uses the GTX30 turbine. They are very similar turbos tho.

I'm on 92 in WA.

I would also be interested in seeing a log.

Just looking at the dyno graph I can see one issue...... your not making any more power above what I'm guessing is like 5k..... what's your boost curve look like?

Well one thing that is for sure I have a boost leak. Just tested last night and I found that I have a leak where my Damond Motorsports throttle body WMI spacer is. Gonna order a couple stock throttle body gaskets and retest.

[Mastertrixter]

Yeah get that shit ironed out. Your missing out on the best benefit of a bt. Power all the way to redline.

Here's my dyno graph comparison from Cobb stg. 2 to bolted & tuned to GTX2867 & tuned. All on the same dyno.



Stage 2 = 254/285
K04 w/ tune = 282/340
gtx2867 w/tune = 380/390

Holy crap man that makes me feel like my GTX2871 should be able to get close to that then. Makes me even more excited to install it!

Would be interested in seeing some logs. Curious as to what your idc looks like? Also timing?

I've always hated how laggy dynapack's makes big turbos look...

My old 3071 could spool to 20psi by 3300 on the street, but on the dyno, never spooled better than 4000...

Here's the 3 logs from the dyno pulls.

[Mastertrixter]

Jebus that's impressive. I need better than 91 oct.

97% idc and 13.5* up top on 26psi is near my meth setup lol

[keychain12]

Guys who have made 360+ with a gtx2867 do you wall have cat less down pipes?
