Ever wonder how far 160lb injectors go on E-85?

Not now. Before the summer is over I'll probably put some Id220s in it.

Nice, madd power for 25psi. 
Time to add the Methanol Injection, Meth will give you the head room you're looking for and keep that MAT temp nice and chilly at 25psi.
Pre and Post-Turbo Injection would be interesting to see on this combo.
What were MAT's at 25psi?
What intercooler?

I will definitely be selling them. If you are interested we could work something out now and I'll just put the 220s in my car.
The dyno sheet says all this happened at under 4300 rpm
Cal, Maybe it was the dyno rpm pick up
Aeromotive Pro Series pump. -12 feed with -10 to the front of the car.

The converter is a Neal Chance bolt-together.
I asked about this and he said that he doesn't use the tach pickup on a sparkplug wire for higher horsepower cars because the data gets skewed. He gets the car rolling to 3000rpms then calibrates the dyno for the pull. I'm sure that the rpm number shown isn't accurate.
In talking to others about this I'm told that this would produce an accurate HP number but a skewed torque number. I really don't know...
All I know is that the real story here is that it used up 160lb injectors which will tell you how much power the engine is making based on fuel consumption alone. And after driving this car I have no doubt this car is an easy low 9sec car to high 8s.
I've driven alot of fast cars, most of them my own (including my mid-7sec Mustang), and my butt dyno is usually pretty accurate.

220's should....
do what you need. May be a handful to get tamed for street driving???
In the "fwiw" dept: I just finished some 550's and 160's for a local shop....[These are staged, w/ the 550's on static when the 160's hit 50% dc.]
He is using strait meth @ 40# boost, 70psi fuel psi....
Is reporting a duty cycle at 95%
He's stepping up to 220/550 combo...

Wow....
I don't know and don't care. The car is a street cruiser and its fricken fast already. I'm not gonna beat it up at the race track.
Make 3 (if the tranny has 3 gears) runs on a chassis dyno in each gear. Overlay all three runs on the same graph. Where the hp (or torque, doesn't matter, you get the same answer) curve falls below the curve of the next highest gear, that is your shift point(s). This ensures that the maximum amount of hp (or tq) will be delivered during a run.
If the different gears causes the dyno to have an incorrect hp (or tq) reading, there is an alternate way to do this with one run.

its2quick - bad ass combo, love the build. Don't doubt the numbers at all, and like you stated its a street car so the numbers don't matter too much anyways.
The one thing I would comment on though in regards to the HP limit of the 160s on E85, is that maybe either your base fuel pressure could be increased or maybe the pump is at its limit or starting to go away. The only reason I suggest this is that I have seen 6 cyl cars (supras) make over 1100 to the tire with 160s on E85. I have also seen 6cyl make over 900 to the tire on a mustang dyno on E85 with 120s and 40psi base fuel pressure and about 88-90% injector duty cyle. That same 6cyl I am sure could break the 1000 barrier (if the motor would take it) with the 120s on E85 with the base FP bumped up as it has plenty of pump.
I agree there no reason to bump the injector size on your beast, as even with your combo turned down its more than enough for the street.
