At a lower power level like 350-400 I can see it being similar, but I'm curious of the differences at ~600 or more.

I like the idea of EFI, but for me I would like to see a fully mapped system with wasted spark ignition control.

What I will say is I was looking at buying the “kit” last month, I was going Fi Tec but was put off by some of the negative reviews, but what I do like about that system is how neat the install is, looks to be very neat and tidy.

Now with the others brands they have a massive amounts of wiring and huge ECU boxes which I feel clutters up the engine bay of our classic mustangs.

As I will not have my car finished until next year, I will wait and see what happens.

I am really tempted to run a 8 stack from Borla, now that is real fuel injection

I am proud of it, and I would love to show off my FiTech EFI, in fact I hate having to point out to people that its under there. Basically, with a Vic Jr intake, and a 3x14" air cleaner with drop base it gets hidden. The benefit to this carb style EFI probably isn't necessarily the way it looks for most people, it's more likely the way it FITS. Being able to just bolt these in place and still use stock hoods, or factory shakers and scoops is a big plus for some people.

With Megasquirt all you need is a trigger wheel bolted to the crank pulley set 7 teeth from the gap and cylinder 1 at TDC, and a vacuum line to the ECU to run. Wasted spark is easy- it batch fires. The Megasquirt unit is very small. Maybe 6" long, 3 inches wide and 2 inches tall. Wiring is very simple and there is no clutter. You can even mount the ecu under your dash or wherever you want it .

Guy i worked with had a thunderbolt clone with dual quads 427 street and track. he installed one of the first CFI setups the one were you just turned like 4 pots in a box. think they only had 1000 cfm units. installed 2 of them dropped his et 4 tenths on a second in the quarter. of course dont know how well he could tune carbs and did know all that much about the build.

If you're going to run wasted spark + batch fire, the microsquirt would probably work as well and it's even smaller. I don't see much of a reason to run a ms1/ms2 over a microsquirt these days unless you are on an extreme budget or feel like assembling a kit. ms3 pro is a different beast altogether though.

Yeah at the time Microsquirt didn't even exist. Microsquirt does look like a cool option though.

How long do you think before Holley makes a TBI that looks like a 650-750 double pumper? That will be a big seller. I have mocked up putting the front float bowl of my 650 on my FiTech. Looks doable!

It really doesn't add much wire clutter if you are deliberate and neat about it. I have EZ-EFI 2.0 and their controllable billet dizzy and the only way you can tell anything is added is that you can see one wire loom on top of my intake. Other than that all of my wiring is hidden completely in the engine bay.

Oh well, never mind. There are no new ideas! How long has that been out?

$2500! Ouch! I noticed the shipping date on Summit is mid Feb. Told you they'd be a big seller.

They came out pretty recently, May of last year IIRC.

You definitely pay out the nose for the looks. Not that much gain in performance that I can tell as far as fine-tuning ability goes. But dang do I want it!

Me too! The cad plating isn't authentic to the original though. That will remain my excuse for not buying one, until the price comes down!

Sniper EFI also comes in "Classic Gold Finish".
