This section needs to be resuscitated!
Any winter engine projects out there? Engine theory you want to discuss?

4 hours and no reply.. ever since Bob passed (RIP buddy), open discussion doesn't exist , unless your willing to throw out a Credit Card # for advice .
Used to be a fun place...

I'd agree with you, but then we would both be wrong
OK..I'll bite, Done with 110, going back to pump gas..
A snippet from the Snow Performance site:Their kit with a carb spacer plate and digital progressive controller can activate at whatever manifold pressure/vacuum you need and ramp up with rpm. Start spraying at say 4"hg, all in at 2"hg... or whatever....Run 10:1 to 14.5:1 compression ratio (or more) on pump gas...
I think it's a pretty cool solution for the guys that have to run race gas, to be able to fuel up at a pump instead.
Just a thought.

These guys seem to be a little more "professional" than "marketing" (or perhaps just better at marketing LOL) ProMeth
My injection system was $450. I picked up a 100 rpm on the top end which surprised the both of us.
I can run 91 octane. When at the river I run a 50/50 mix of 100 & 91 with a little Marvel Mystery oil. Next season will try another pulley I have, 12 psi boost.
In the pic you can see the tank in back, injection nozzles on each side the the carb hat. Once you figure out where everything will go it's a simple installation.
Wouldn't hurt to have a conversation with Rodney to see what his thoughts are about your application.

My project engine, a twin turbo intercooled EFI 5.3LS (which I should resume shortly after the first of the year) should run great and provide more than I (or the boat) need/s on 91. However, I'm VERY interested in being able to fuel up anywhere on the water. Which means, being able to do it on 87 would be a huge bonus. Sometimes premium isn't available. It would make the whole package even more user and destination friendly.
I think I will get in touch with him when the project gets to that point
Just a 79 CP, no need to be King Shit...getting older
Gen 4 Bowtie,SRP pistons, scat guts,cam re ground by Barry's friend, new to me Edelbrock tunnel ram, Davici flowed my 750s to 910
that's about it
Sounds like a solid build. Do you think you'll keep your performance with the additional cubes? What heads?
Real good match for the cubes.
What do you mean by "nailing down a tune for 14:25 isn't easy"? 14.25:1 static compression? If so, I would imagine as such. Shit, that's on the edge for a lot of ugliness in anything but a diesel.
Make a program for whatever fuel you want to run.
I made a gas program for my setup and set the rev limiter low so it could never hurt itself.
It has gas in the system for the winter.
I also have an E85 program and a Methanol program.
I have a drum of E98 so a little tweaking on my E85 program and I'll have that capability too.
This is one area where I like the FAST XFI better than the Holley HP system.
The FAST uses a fuel energy constant and will read in Lambda.
The Holley does not use a fuel energy constant and will only read in A/F ratios.
You have to input A/F ratios on the target map with the Holley system which is time consuming.
Once the target map is setup the Holley self tunes the main fuel table easier and better than the FAST.
