I have a 93 mustang coupe with a lq4,l92 heads, with a 750 holley setup for e-85. My question is where do I start for jetting with a plate system. The kits an edelbrock plate kit. Tried calling edelbrock on where to start and they say they don't deal with e-85. Any help would be great Thanks.
Please let me know what other info you need to help.

 

what fuel pressure are you running??

 

Fuel pressure is at 6.5lbs. I'm running a a1000 aeromotive pump -10 feed to a dual -8 to each bowl.

 

A lot of people say to start with the manufactures recommended jetting for gas and it will be pretty close to right with e85 since they always have the tuneups rich in the instructions.

 

Ask the master nitro Dave . He just complete a custom set for me with E85

 

Do you have jetting already for non E-85 on 6.5 psi??? if so you can add 28% to the fuel side and you should be good. If you do not already have jetting pm or call us and we can get you squared away.

 

And this is why N20 outlet is the best for Late Model vehicles or anything that is considered "too new" or "we don't do that here".

 

For future reference:

E85 Jetting Conversion
25-30% x Fuel Jet ( 25% or below = leaner jetting, 30% or more = richer jetting, 28% = Pretty much spot on )
Ex. 42 ( fuel Jet ) x 1.3 or 42 + 30%
