I haven't done any 4th gear pulls yet. But on 3rd gear I am seeing 460-470whp vs the 420whp VD that I posted before

probably but I want to keep my setup as simple as possible. I have the 2200cc injector here so there is no really any reason to change anything else

with a rewire, the walbro 400 is only capable of about 310lph when running 27psi of boost and stock fuel pressure. his 1200cc injectors (if actually flowing 1200cc) are demanding 288lph at 100% IDC. now, if he upped the fuel pressure to 55psi base (1200's now become 1350's), his injectors would now demand 324lph at 100% IDC, but his fuel pump would now only be capable of about 260lph. so anything over about 80% IDC would be out-flowing the fuel pump. he could honestly only increase fuel pressure to about 50psi base if he wanted to stay within the flow capabilities of his fuel pump. this would give him approx 1280cc of flow at 100% IDC.

when he goes to 2200cc injectors, anything over about 60% IDC is going to be out-flowing the pump.

once you max out the flow of the walbro 400, you have to either start looking into a larger/more complex fuel system or a BAP. if you don't, your only option is to increase IDC to compensate for low pump output. doing things this way may work (there are tons of people running 1600's on walbro 255's with like 80% IDC or more), but it leaves ZERO headroom in case of an issue, and you have to wonder what your psid is dropping to when running so far outside the maximum flow of the fuel supply.

I have the E85 walbro version. I think it flows 460lph or something like that. I don't know how much it will flow at 27psi... I think I will have enough fuel will see

the 460 = 416 = 355lph flow rate at 13.5V and 70psi...this will get you to approx 67% IDC on 2200cc injectors (assuming they actually flow 2200cc and you are running 27psi of boost...higher base pressure or boost will drop this number lower)

FWIW - Walbro 460's run out of fuel at about 600whp on the dyno with e85. That's about 60% duty cycle on 2200's. But dual 255's can go much farther. Never tried dual 460's though.

Really? EVO's have hit 700whp with the Walbro 460 pump.

I don't think I will be close to 600whp anyway

Why comparing the Evo to a Subaru. The Evo's engine is 100's more efficient than the EJ.

Actually, I think it depends on the dyno. EVO and Subaru's both start losing fuel pressure at ~600whp on our dyno. It's a Dynapack as well, and to further dress in my flame suit....

Subaru's and Evo's both make similar power with a proper build and the same size turbo on the dyno.

I bet I will make more power then this fully built EVO 2.4L FP black EVO on E85 with less boost... the 545whp pull haha.

The other pull is the same car with S3 cams, aftermarket manifold etc etc.

That 629hp pull looks pretty good on the Evo, maybe you need bigger cams, aftermarket manifold, etc etc. Hahaha

Anyone tried vp air race fuel yet nobody seems to answer me when i ask. Or they just don't know what it even is lmao. Says its good for high boost cars so I'm guessing its highly oxygenated. Has rich and lean knock threshold bet its fun to tune on lol.

Maybe I should try 34-38psi like the EVO guys

From what I seen on EVOM there is not really that much of a difference. Mike at AWD Motorsports who has tons of EVO records 8sec etc etc only runs E85 he says that C16 is a waste of money.

I did a 4th gear pull today, it only gained about 10-20whp in some places. This is with 1-2* less and 1-2 psi less than the original tune. I am swapping the injectors this weekend.

Nobody has made 700whp on e85 with a single walbro 416.

STM with the regular walbro 400lph made 572whp on their mustang dyno which reads 13% lower than a dynojet.... about 646whp dj...

I would say it would be close

Maybe you should.............

I don't even know what my Subaru would make at 34+ psi. I probably need a bigger turbo. But since we are comparing, here is my VirtualDyno. Graph looks a little stupid because I can't get a clean pull without wheel spin. It needs to get warmer out here.

Thats a HTA86 right? what is the max boost you run?

What transmission are you running?

It looks great man, congrats

If FP says the old 8cm Red is safely able to do 35psi, then your 35R should definitely be capable of running that...maybe not holding it all the way to redline, but you should definitely be within the turbo's operating range running mid-high 30's in the peak tq area.

No, my car has a GT35r not an HTA86. I've never went over 30psi. PPG 5-speed is the tranny.

But the point was we are comparing similar turbos here. IMO flow-wise the FP black and the 35r are pretty close. You posted an EVO with 600+ hp, I posted a Subaru with 600+ hp.

I think that your car certainly has 600+whp capability in it, just finding the bottlenecks is a pain. Oh yeah, and being mighty careful of those stock cylinder walls!

Thats very impressive... most GT35R's here only make around 520whp VD.. with that boost on E85. What gas are you running? how much timing? what AR?

Yeah the turbos are really close my is supposed to be only 3lb/min bigger but since I am running stock location and small hotside the increase in size is negligible. Probably the only bottle neck that I have right now is that I am running IWG. But with FMIC it seems that it holds boost better at redline.

any plans on going to the track? is that your DD tune?

We need a thread title change, no more tmic madness.

If u end up doing a big fuel system, let me know, I have a great setup I read of that we can emulate. Tell ron to give her some big boost, if u have the fuel.... Hi ron :wave:

I've ran this setup in similar fashion for many years.

1) Running e85 from the local station here ~75% E85 right now. Not gonna run more boost til' summer
2) less than 21 degrees of timing at redline
3) .82 t3 housing
4) I've been to the track lots of times
5) Yes it's my only tune, but I wouldn't say my Subaru is my DD. I lost interest in 93 octane.

PM me for more info.

Ok is just weird that it makes so much power vs my car and other 35R's. You must be doing something right . What were your times and mph at the track ? I will pm you for more info.
