need some advice on injector size runing 6262 turbo and e85. current mod list 109 block 20 over dimond oistons,h beam rods,forged stock stroke crank,billit mains studed,revolution 206/210 roller cam ,champion ported iorn heads,hrland sharp roller rockers 1.65,e85 ss fuel pump,60lbs injectors,teflon lines,3inch dp external w/gate 4inch rjc single shot exhaust built trans 3200 ptc l/u converter.would like to run about 26lbs of boost. any advice would be great thanks...

youve already spent a lot of doe ,so it seems logical you will, at some point, turn up the wick...the 80Lb inj will support you til around 600 hp, on e85,or so,which you can make if you crank the boost up...(80s will be getting close to maxed)..you need the 120s and a new chip. If/when you go there ,you will most certainly need a great converter to harness the power..without it your leaving ALOT on the table ,period. its a 'must have' item top pick=PTC 9.5 N/L. Also...with the big f/pump and injectors ,running e85, i would personally need to redo the fuel lines -8/-6 as all that old stock stuff may or may not flow the best as it could be...not to mention if any debris starts to get flushed through : o (big bitch then) If your car sits for long periods? you may give thought to what is that old e85 fuel eating ? some have no issues ..some do. i personally didnt want the aggro. Plan to part with another 3 g's or so. All that said...the car will be a low 10 second rocket.

95lb injectors are another possibility. We put 95's in Bobby Smiths car and they behaved just like 80's with a MAF based control system (TT 6.1) with stock like drivability. Plus they are a great match for the big walbro pump.
I run 120's myself but I have found that they can be finicky with a MAF system when the chip tries to due a closed loop learn at low idle. The 120's are a bit on the edge when trying to idle at stoichiometric especially with a cam. But if you're running speed density then that's not a problem at all. If you boost the voltage then that big walbro pump will come darn close to fully supporting the 120's too.

The 430 lph pump: flows about 94 gph at 70 psi (43 base plus 27 boost). That's just enough fuel supply to feed 95# injectors at 100% dc or 120# inj at 80% while they are at 70 psi.
The compressor looks like it flows about 70 lb/min, and at 11:1 afr that's enough air for about 63 gph of gas or about 85 gph E85. That figures out to 6 of 85# inj at 100% dc or 100# inj at 85% (and 27 psi boost).
So the answer is either 100 or 120 # inj to max out your current configuration.

Will 95# injectors work without modding the ecm? Im doing the same thing but i already bought 80s and an e85 chip from Eric...

Deka 80's are a hi imp inj. Run them at LS fuel pressure of 4 bars, and have a 94+PPH inj.
Chuck .. don't bother .. this has been brought up over and over ... falls upon deaf ears .. these guys want to drive their injectors with 40 psi and 11 volts at the pump and see 60% duty cycle...
500 lph pump 200 pound inj no rail pressure 50% duty cycle
Funny I've pushed 36 pounders on V8's to 140 ...
72's have been 140 in V6's on fuel ... 80's have been middle 10's on E85 in V6's
and I agree with the post above ---- 128-129 is about the limit for the 80's ... and a lot of it depends on the setup
Whats it worth to you to see it ?? on E85 and a 80# injector with NO WEIGHT reduction other than welds on it ?? PUT UP OR SHUT UP NOW .

You keep making the claim that this car has ran the numbers. Several people here have met 100% DC using 80# injectors at the 11.0 range. You keep hiding it behind "its a grudge raced car."
Just show us a 10.40-10.60 with 80's and E-85. Take the plates off and dress the driver up like a ninja to keep his identity hidden Lmao.
