Are 8 enough for my 351C?.
George has 16. :-D :-D :-D

What Fuel?

Depends on power & fuel...
BTW, George has 18 injectors. 2 set of electronic & 1 set of mechanical. 8-)

In order to obtain increased capacity, a certain tuner, whose name appears above, has used propane injectors (which may be more economical than especially large gasoline types).

HP X BSCF [.55 -.65] divided by # of injectors x duty cycle not more than .9O % result in lbs.
from Holly.con EFI go to Dominator ECU unit scroll down, lots of different questions answered.
WRONG directions, but the formula is there somewhere under tech :-D

Ethanol.

I just saw a photo and thought he had 2 per cylinder. Thanks Michael.

What ECU are you using?

I always wondered what CC to lb was divide CC BY 10.5 2200 BY 10.5 = 209.5 LBS PER HR.
Now got to find formula for lbs per hr to hp :-P It's in the Holly EFI site.

Fueltech FT350.
My expert says it's fine for my application.

Ok found it injector size x duty cycle divided by BSFC X # of injectors
209 x .8 divided .5 =334.4 hp per cyl x 8 = 2675.2 hp
Formula means injector size will support that much hp.

Thanks so much. To be honest, all Greek to me but if that's calculated on
what I have then no problem. I only need 40% of the 2675!!!!!.
ONLY!!!!!?????? :-D :-D :-D :roll:
JL100%. :cheers: :cheers: :cheers:

The 2200 might be to big.

I liked running ethanol. It has a very big tune window. 2200 cc will be fine.
I always run the biggest injectors that I can get away with. As long as you can get it to idle, it will more of a “timed” injection than smaller injectors.
I hear great things about FuelTech.
How much boost do you plan on making?

Rob, I have Nassen Padyachee handling the EFI, turbo and Fueltech system.
He's the local agent and held the record for the fastest FWD drag car in the Southern Hemisphere for 9 years.
He gets flown out to the States on a regular basis for NHRA events due to his skill on tuning Fueltech equipped cars.
All this new stuff is beyond me but Tom says I need 1000HP to reach 300 with what I have.
The guys tell me what to build/have made and I go with their advice.
I'm a good assembler but not an engine builder.
Nassen is the nicest guy you'll ever meet and we have a barter deal going. I make Carbon parts for him and he supplies
BOVs and wastegates etc. It saves on spending. My budget is severely limited. My friend and Carbon supplier Gebi gave
me a roll of some very good Carbon for Christmas.
The Flyer should be called the "Miracle Machine". :cheers: :cheers:
