Efr 9180c iwg 823whp 558tq
I had a day off work today so I got to work on my tune on the Dyno with the new setup.
Power mods:
Sleeved ERL 2.0L, 87mm 10.1CR CP pistons and Carrillo Pro H rods.
AMS TMP cams and Kelford springs.
Full Race EFR IWG turbo kit, upper IC piping and intake.
Borg Warner EFR 9180C IWG turbo, .92ar hotside.
TurboSmart dual port IWG with 26psi springs.
Akrapovic exhaust (quiet/restrictive).
Depo 3" LICP.
Greddy 33F IC.
Moroso Oil pan.
E77 fuel.
ID 2k's.
Fuelab Electronic FPR, 8an 6 micron fuel filter and 42402 fuel pump.
Radium 2.5L surgetank fed by a Intank Walbro 450.
Custom dual 10an catchcan.
Stock valves, ports, intake manifold, throttle body.
I think this is a great turbo but I don't really think it shines in this internal wastegate configuration, and at this point, a really small hotside.
These runs are at around 37psi and the turbo is running around 108k rpm out of the recomended 116k so the turbo probably can do 40psi to 9k rpm but it wasn't making more power on the dyno (probably due to heat soak, it was like 90* in the room) with the added boost so I stopped here.
The tune is also much less aggresive then the last one on the 8374. 770whp (and 800 unoffically) on the 8374 was just to much for that turbo. This time the setup is more happy and I don't feel like its going to blow up the next pass LOL.
Anyway, to the numbers!
This was a 3rd gear pull:
This is the same 3rd gear pull compared to a 3rd gear pull on the 8374 from the same day it made 770 and both pulls are very close in boost:
And this is a 4th gear pull and the 4th gear pull on the 8374 that made 770, also close on boost:
Keep in mind that the car now has a Shep 4.30 final drive. I don't know if that makes a difference in power or not but I figure I mentioned.
4th and 5th gears really need more tuning but even on the dyno is really scketchy running the car in 4th to 9k so I'll reserve that for fine tuning on the track. I'm sure the car will make 850whp in 4th once that's done.
Overall the tune is not fully completed, lots of MIVEC and fueling work still need to be done and I'll slowly work on it as I have time but I don't really want to push it more power wise as I just want to enjoy and race the car the rest of the year.
I do feel that the stock throttle body, intake manifold and/or the stock head ports are holding me up from easily making more power. I may do the MAP Rev3 manifold just to try to even out the flow in to the cylinders.
EDIT:
I did a pull this morning since it was a little cool for a South Florida Summer around 75* and got some impresive results. I always know that the car makes more power on the street then on the dyno due to the fact that it loads the car better, gets more boost,carries more boost and has good airflow to the intake, IC, etc. On the street the car does 38psi and holds 37 to redline. Take it as you wish.
The 823hp pull is the actual pull that made 823 on the dyno yesterday.

It's def laggier but I've since done a lot of low end tuning with MIVEC, timing and AFRs and it's honestly not bad at all. The turbo can take a surprising amount of valve overlap before encountering surge.
I also changed to the Shep 4.30 final drive so the car feels different from that also.

I would think so yes. Ideally you'd have a 3.5" downpipe too but the exhaust increase in size would for sure help, not sure how much but you can pull the exhuast off and do a pull and see to know for sure. I bet you pick up 20-30whp with no exhaust.

A ported head, race manifold, and external dumps. Will make a tremendous difference. I bet your car would hit 1000 whp. Car must be a handful on the streets with all that wtq, must be scary.
