get rid of that a.f.c.

 

Or a 30R thats tried to relocate some sand or something, thos tq numbers seem very low, when were you making peak boost.

Scorke

 

His numbers will be low because his timing numbers will be off. Get a custom relash and bump up that rev limiter to atleast 8000!

 

Are those 91 pump numbers.Looks pretty laggy for a 30r regardless of tuning.What are your mods.Are you running a stock cat or exh.Need more info?

 

I have all the mods ready and yes it was on 91, thta's what I like to hear too laggy for a 30R
what do you guys think? too laggy for a 30R??

 

Just going by the dyno chart, my guess would be that this is a 3076 on 91 Octane (edit: I guess it's not a guess anymore ). Judging from the late spoolup, I'd also guess that you have one (or more) of the following issues:
1.) poor choice of turbo housings
2.) poor choice of cams or cam gear settings
3.) poor choice of exhaust manifold
4.) some kind of mechanical issue (install/bad parts, etc.)
5.) poor tune

Is the equivalent of ~385whp and 350ft/lbs really that bad for a GT30XX on 91 oct and a SAFC?

After all, I'll bet he's not running a ton of boost. I agree that it does appear to be somewhat laggy (which may be rectifiable), but it seems plausible that better fuel and more boost pressure will increase the power in the familiar fashion.

 

Yeah, the whp looks to be in line with what I'd expect on 91 Oct. My setup (3071) put down the same amount, but that was on 93.

or maybe it is not a GT30R afterall?

i have 264/272 cams
i have the RNRracing manifold
i dont think I have any mechanical issues..

 

How much boost are you running? I

 

You are currently running a 2.3l, correct? In which case this whole discussion is a moot point, since the car is no longer in the state that it was in when it generated the dyno chart in the first post.

I think he is hoping someone has mistakenly sold him a larger turbo then he wanted to get.

 

FWIW, my 3071 hits peak torque (on both Mustang and DynoJet dynos) at 5100rpm. My power and torque are in the same ballpark (350hp/330tq @23psi) with the mods listed below. So, unless there's a problem somewhere, this appears to be a laggier turbo than a 3071 on a 2.0L.

 

edited...found the answer

 

so you think it don't seem like a GT30 with ball bearing?
but aren't all gt30 ballbearings?
