Am I the only one that sees squiggly lines on a bright white background??

 

Im sorry if the plots didn't show very well, you have to click on the "thumbnail" to get the bigger version, it seems to display ok then.
The graphs are all the same run with different parameters displayed on the right hand x-axis:
the first shows whp/wtq, in dynojet numbers
then the second show the same in MD numbers
the next two are afr and boost

 

So 408whp and 319lb/ft on pump gas huh. Certainly nothing to sneeze at. I might have to rethink my turbo choice for my power goals though. Was hoping to hit 400whp on a 7064 with 91 octane. Appreciate you sharing the info. Once you get the rest of the issues sorted I'm curious how much power you'll pick up.

 

You can ask the RG guys, but I think that they got a bit more out of it (??up to 460 whp, with meth) but de-tuned it to ~400 as we are learning a lot as we go along and dont want to get ahead of our selves. I dont think we are maxed out yet, but think that with the right tweaks and a bit of luck we can max this turbo out with the current setup (plus this is my first car with any real power (my last ride was a suzuki GSX-R1100) so I'm learning lots too ).
the cams added about 50 whp!!!!!! but all up top, with sig change (loss) below 3k
with "just" the 7670 in traffic it was pretty effortless to drive, not so much anymore...
(losses, according to the "***-dyno" because the curves apparently dont shift much before and after and therefore supposedly not much change, but it feels very different!)

 

you STUPID IDIOTS. This is a low reading dyno. Stock EVO X's dyno 190whp on it you braindead jackasses. The fp black graph is a 75% increase in power over stock you birdbrain morons. There's nothing wrong with it, JESUS.

 

Who pissed in your Cheerios?

 

Lol, gets pissy on an essentially dead thread.

 

I had the efr but sold it

 

I was shopping around for EFRs at one point, the 7670 was only about $30 more. Probably worth it?

Was trying to decide between the two, never came to a conclusion!

 

Apples to oranges.

The comparison is between stock framed turbo vs the baddest turbo in the market.

 

Hi guys, the car is going back on the dyno this week to try and optimise the no meth, pump gas tune.
We had some tech difficulties with maintaining boost at higher rpm (we think it may be a problem with the base maps). Then I actually blew the UICP off on the front straight at the local track and then the hose connecting the boost controller devoloped a hole where it touched the firewall (we've resolved these issues, though, occasionally I trigger an error code and go into limp mode).
Our goal is to get a good solid ~400+ whp off meth.

 

thought i'd bump this thread to confirm that RG's Mustang dyno isn't nearly as low reading as some people make it out to be.

340whp on a FP Black because low reading dyno

nah, 380whp on a CBRD BBK Full on 91 octane, stock cams

 

You can't compare your graph to another dyno, not really apples to apples and not even the same motor dude.

I will agree, both these results are low, so the dyno could just be extra heart breaker. Peak numbers aside you can see the spool up comparisons and its impressive that they are so close considering one is a t4 framed turbo.

I am moving to this exact turbo, the 7670 .92 A/R this spring on my setup and will toss my car on the dyno to compare to my old fpblack setup. My fpblack made 570whp and I am hoping this turbo will make 600whp and have better low end but we will see.

The EFR stuff appears to be pretty legit, they are posting up a lot of time attack wins and some solid power bands on multiple platforms. There is still just not a ton of data on them yet.

 

so for fun we did some tuning on 116 octane race gas, no meth.
short answer: 445whp/334wtq, and pulls all the way to red line at 9k
Thanks to Mark and Tommy for the tune and for figuring out the problem we were having. We had trouble making power gains at high boost over about 7500rpm. We were getting this weird power fade, that looked like the ECU was doing something, but we couldn't see what, and could not make and sometimes couldn't hold power over ~7200-7500. Anyway Mark noticed the 3-1/2" silicone turbo intake elbow felt "floppy", so Tommy observed it thru a pull and under full boost the pipe was collapsing!! So... Mystery solved. Now, I guess I need a hardpipe for that section, Tommy fabbed up some aluminum "stents" that we placed internally and clamped into position. With the new and improved "non-collapsing" model of turbo intake they were able to produce the curves shown in the dyno sheets. The solid lines are race gas, the dotted lines are 93 octane pump gas with 100%meth injection. The same mustang dyno at RG racing was used, the pump gas numbers were from the spring/summer while the race gas session was done on a cold, very rainy day (prob ~10 celsius).

 

Well the boost is lo also but I have an Fp black on my car with map race manifold, map open dump dp, turbo XS exhaust with test pipe, FIC 1100 Injectors, Aero 320 lph, Agency Power adjustable BOV, ETS 4in fmic and all hardpipes, and ETs intake and i made 435awhp 335tq on 93 octane @ 27psi. Oh and that was on a dyno jet
