I'll have to dig out a log of when i was working on getting my boost to be flat through the gears (never got there, gave up on that but that's for another time) but yes i was holding 26~26.5 at high rpm through gear changes and IDC's were in the upper 80's and the only time IDC's went crazy high was when i was having problems with the lower bound fuel table that you helped me because AFR's went pig rich during upshift...
Anyway, in the mean time, here's a recent log that i did and you can see there's still head room for more boost

 

Hmm, I have a hard time believing the 1100cc's are almost 30% less IDC's then my ID1000cc's.

I'm starting to wonder if something else is going on with my RA....

 

Well when I first switched to e85 about 5 tanks ago my AFR's would go very lean at high rpm but only after 3 gears, I knew it wasn't the injectors because IDC's were below 90's for 2 full gears up to 7500 rpm.
So I decided to pull the fuel pump to check things out and I noticed the hose coming out of the pump looked like it was getting pinched when the pump assembly gets compressed in to the tank, changed the line and moved the pump on the hanger so the hose didn't get pinched at all and the problem went away compleatly. You would think that the AFR's would have gone lean I any scenario but it didn't , have you checked your pump , filter and lines?

 

BTW, tomorrow morning is supposed to be "cold" (in the 60*'s) here so I'll take a log and I'll let you know the IDC'S for the run

 

Bryan, didnt you get one of those dw400 pumps? Not working out or just not enough time to put it in yet?

 

Have you already tried the relief mod, according to david it raises fuel flow through the curve and not just above a certain pressure.

Also I'm wondering have you looked to see if the stock fuel lines from the tank are the same diameter as evo x's perhaps they are smaller creating a flow bottleneck.

 

I seem to recall that for E85, my FIC1100s scaling is about 680 cc/min and my ID1000s scaled out to 580 cc/min. That's almost 20% higher scaling, so I could believe that the FIC1100s can support the same power at 20% less IDCs than the IDs.

The FIC1100s in 3dman1's Evo 10 are going static at right about 525 whp:

If I do the math, it looks to me that ID1000s should be done at about 450 whp with E85 on an Evo 10.

 

Yea I should pull the assembly and take a look, just in case.

Relief mod meaning drilling out the return? No I have not yet.

I also haven't checked the fuel lines. Are you talking about the actual hard lines?

I have one of those new Walbro 400's but I have not installed it yet.

He has a double pumper right? This is starting to sound more and more like a pump issue with my RA....

I'd venture to say my RA is currently right around 400whp on the GST mustang dyno. It was 370whp before I upgraded the rear OEM catback.

 

Yes, double pumper with 50 psi base pressure. 400 whp on GST MD is approximately 440 whp on a DJ. If you're on a single Wally at 44 psi base pressure, I'd say that you've hit the wall for those injectors.

 

I really wish I could just buy some 1200-1400cc injectors and put in the Wally 400 and not have to worry about anything....

I'm happy with the car right around 400, don't need anymore in the RA on stock motor/SST. I also don't want to punch a rod through the block running 14 AFR's at WOT with a craptastic fuel system either...

 

Wally 400 + AFPR might get the job done. If you include FIC1100s, you're sure to be there. I think 3dman1 might be selling his FIC1100s soon.

 

No punching the release on the pressure relief valve on it. There is a write up on here somewhere.

Ya I mean the actual hard lines, I know it seems weird they would already be maxed out but if they are much smaller then evo x hard lines perhaps they're the limiting factor. If your the only person with this much hp on a RA then maybe its something to look at.

 

Bryan, what are your injectors scaled to? My FIC1100's are 665.

 

562

 

So a set of FIC1100's would give you 18% more fuel. Seems like an easy fix.
