So Since we are talking about ID injectors, they have a 1000cc and a 2000cc.
I have been told I'm 400cc short of 300hp and i have upcapped Secondaries flowing 880cc's. If I swap in the 1000cc's that gets me 40cc shy of the desired fueling.

I'm guessing i need to swap in the ID2000 's in the future.

(remember I'm a Four Port kinda guy )

I wonder how the Elliot and Jeff are doing today. Hmmmm

 

Aux ports open first graph

And open vs closed

10 PSI, NO AI, Stock Block

 

DAAAAAAAAAAAM!

Stock Block...OMFG!

 

HOLY CRAP!

I can't believe my eyes!

 

wow

 

BAM! Do you have the boost and afr graphs?

 

/\ +1 Awesome numbers .

Corrected or uncorrected ?

 

Omfg!
Congrats guys, that's awesome!

 

Thanks guys. Sae corrected.

09factor is next, dave get some bigger injectors and let's do 15psi I want to see 350 ft lbs of torque . Now that would be quick..

 

wow big things! you guys just raised the bar dramatically! any videos?

 

wow 426 out of 10psi, holy ****

what are your egt's like?

when is full boost hitting?

 

Personally, I think the 360 HP dyno looks like more fun, but that is just my opinion.

We didn't have any telemetry for the EGTs, but I suspect they were pretty low.
When we first started tuning, we had a pretty good misfire going on up top which would cause a pretty significant boost surge from the elevated EGTs. Once we got the fueling under control, that went away.

We loaded the dyno at 3000 RPM before starting the run. The turbo would start at 3 PSI or so at that point. It hits the full pressure at 4200 or so, but, as you can see, it is making pretty good torque by then.

 

I'm guessing you didn't want the lean spike from the ports opening ?


That is the really surprising thing (to me)- low down torque looks to be excellent .

 

Keeping the ports closed to 6700rpms~ish yields a lot more torque down low( just look at the graph). Having a functioning SSV would really make this powerband incredible.
All the kits from now on will have enough space to allow ECU operation of the SSV valve. I was under the impression that the SSV was basically useless on the turbo cars, so I didn't accommodate it for this build. I preferred the extra downpipe space as I originally didn't build this turbo & downpipe on this car.

Vidoes are coming! We are also re-upping our vendor status...

 

was this "360hp" done Before the final run?

looking at the dyno thread brettus made your car's 307s still makes more power lower then the top mounts


thats neat, I would think with the smaller T3 flange that EGT and Pressure would be higher, I really don't know the size difference perhaps the t3 divided is only lightly smaller.

 

SSV or Aux ports ?
Yes , having fully functional aux ports will indeed give you an awesome powerband . Some tuners leave them open all the time to prevent a lean spike but that does leave some on the table down low .

 

With the aux ports operating normally the curve will actually be above the 3071 all the way pretty much . That I find staggering for a large turbo .

 

He meant AUX, not SSV.

The 30rxx still beats it in torque before 5000 RPM, but total power isn't as high.
Different animal.

 

Yes only by a whisker though . Are you surprised how good it is low down ?

 

but its not about max power, its about how it feels


so am I incorrect about excessive pressure and heat on a smaller size exhaust housing and flange?

 

So, can we now agree that most were under estimating how much this motor can flow w/ the restricted exhaust ports. Nice Work fellas.

I can understand why you might think this for the street, but the later is the better.

 

w/ the restricted exhaust ports

I did't see a port on this block in the mod list, what are you referring to?

 

So the SSV was permanently wired open for both dyno graphs obviously?

I'm still blown away that this was achieved with an un-modified motor...the results are just all the more respectable...

 

read again, one was tied open, yielded good top-end power
other run was tied close yielded higher low rpm power but top-end suffered

hence leave it closed till 5300rpms then open it = best turbo rx-8 dyno yet

but it sounds like how this kit was built, the AUX will no longer work with out a different down pipe

 

No, actually I understood it pretty clear the first time...the AUX ports are open on the first graph and closed on the second comparison graph, E mixed up AUX and SSV, nothing was mentioned about whether the SSV was open on both graphs but they obviously look like they are, I just wanted clarification. Right, the AUX port actuator won't work with the dp in the way, which is fine for my setup and I'm sure Jamaal will leave his open too with this setup...
