Hi...I'm a new member.....live up on Skyline about a mile from Alice's. I'm doing some mods on my ride and have been reading the ads regarding Eight Stack Injection. Does anyone have one installed and any pros or cons would be appreciated.

Thanks....Limpopo .....Jack Mccloskey

You find dozens (if not hundreds) of people using the various 8 stack systems, with varying degrees of success.

Any individual runner intake system is going to be inherently more complicated than anything with a common plenum. They can be made to work, and work very well. But you have to spend the time and learn how to do that.

For people who have never worked on them, and performance EFI system is quite complicated. The sales brochure will tell you that's the system is completely self tuning. They never are. Some are better than others. And the ECU will tune itself fairly close. But you have to do the final tuning yourself.

I think it's great, and I really like mine. But it's not for everyone.

TWM/Borla with a Mega Squirt. TWM good,,, Mega Squirt way to complicated. Get professional help from the guys that do it for a living to set it up. Don't let Billy-Bob down the road convince you he knows how to set it up. Chances are he doesn't.

read post number five by me.

I have not run my Eight Stack system yet. Well let me say that when I tried I had so many problems with the motor and the system that it would not run correctly. Intake leaking, wiring problems, program screwed up, etc.
Those problem are being corrected and I look forward to driving my car with a beauty fuel injected system. The best of all the worlds.

You can not go wrong with buying a new Eight Stack system.

pics of my car just before I removed the body for paint. Body still in paint shop and I'm building a 347 to go under the injection system.

I have had this Imagine Injection on my car since 2007 and have liked it very much. The original ecu on it was a FAST XFI and when tuned correctly worked fine. My problem was that I never learned to tune it my self and good tuners are hard to find. Lots will tell you that they can tune FI but not many can really tune the multi port stack systems. One tuner totally f'd my ecu in 2010 and I switched over to the FAST EZ system. It is self tuning and has given me what I call a 90% solution. If I were racing I probably would want a more tunable ecu to have an edge on the competition. For the rest of my driving use this system has been great. I would highly recommend it.

Interesting. That sure looks like a Momar EFI system. Momar went out of business about 8-10 years ago. I thought that was too bad, because they were the best throttle bodies on the market at that time. Nice to see something like that is still available. I wonder if they're the same????

when I bought the GT 40 the previous owner installed the system he bought on the car and shipped it. It would crank but ran very rough blowing fire out the stacks and exhaust. I and my buddy tried for a month to get it to run correctly. When it idled it was at 54 degrees timing. There was a problem with the vacuum which effected the computer.
I gave up and pulled it off and call Eight Stack. They help me with several problems. Two years later I'm shipping it to them to go thru it and check everything. I have the car torn down to the frame for a total rebuild, nothing was right.

If you think my written skills are poor you should hear me talk. Sorry.

I'm trying to explain how Eight Stack has helped me. I believe that my system will work perfectly when I received it based on the help I have received from them in the pass.
Others have PM'ed me of the same experience they had with Eight Stack and are very pleased with the way their injection system works.

Hi Jack,
which engine are you running ? I may have a new Inglese 8-Stack Efi with FAST ECU to sell for a good price......it's for a Ford SBF engine....

I use this combination on my ROUSH427R and it works perfect !

If you're interested, please contact me.

Best,
Stephan

I have the 8 Stack system on my car and love it, starts up on the turn of the key and shuts off the same way, no gas smell (My wife loves that ) But you need to have a professional
Install it. It's not plug and play.I have over 2,000 miles on mine without any problems. George

If I wanted FI I would take a cardboard box and stick 8 toilet paper rolls into it and place it over my Holly Street Avenger when the car is parked. Remove the cardboard box when I wanted to drive and enjoy the Holly as I have for the last 7 years and 24K miles...

Sorry, I just couldn't resist. I have yet to meet anyone (in person) who said, "My FI is perfect"! To me it's like having 8 separate downdraft carbs that are never in sync.

Love the look, but if I ever thought about FI, I would go with something like the Edelbrock system. ...Good luck, I hope you find one that's worth the cost and performs correctly for many miles to come.

Eight Stacks can be tricky and need to be setup by someone who has access to technical support from the vendors and the talent to make it work, then it needs to be tuned. -- however there is a new product we saw at SEMA where the Inglese 8 stack can now run on the self learning EFI controllers. However there is more to a EFI system than the FI....the gas tank , fuel lines and how the pumps are powered ( and when they are powered ) are all of concern. -- we would be happy to show you fuel injection setups on my Cobra and Daytona Coupe ( panavia.com )
