The super sniper EFI was $1500, a boost referenced 850cfm carburetor is not much cheaper at $1100-1200, the main reason I went to fuel injection was not having to worry about going lean under boost and the timing control offered by the efi. It actually cleaned up the engine bay by removing several systems that were no longer needed as the sniper now controls the timing, boost fuel enrichment and the water/methanol injection instead of a separate module or solenoid.

Other than ECM’s themselves, and direct injection (not supported aftermarket) EFI really hasn’t changed a whole lot since it came out. Started with TBI, then port and it’s all nearby the same. The ECM’s today are far more advanced than those in the ‘80’s and ‘90’s but the hard parts are all very similar.

I agree, they still need input by sensors but even though the theory is the same, the way that they make the sensors are different. If you look at and compare a mass air flow sensor for an IROC-Z to a mass air for a new Mustang (or whatever) it is HUGE compared to the Mustang. The new ones are tiny in comparison. Sensors like O2, cold air, knock, TPS, MAP, are all very similar still. Still more advanced but very similar. It's the main unit that changes every 10 minutes.

Electronic multi port fuel injection predates TBI by several decades, the first was the Bendix Electrojector in the '57 Rambler Rebel and '58 Chrysler products, while it was a failure at the time Bosch bought the rights to the Bendix fuel injection and refined it into a reliable system that was reintroduced in the late '60s.

Tons of the original Bosch D-Jetronic systems are still on the road today, early Volvos, Jaguars and several others adopted it and the later versions and never looked back.

My IROC and Trans Am was all Bosch from the factory and not very reliable.

A lot of people that hate EFI never took the time to understand it

 

[Canadian country boy]

That's exactly correct. I took the plunge in '91ish with my IROC and forced myself to learn it, and then after thinking I was the next John Lingenfilter my buddy and i built my Trans Am with 100% full custom system from the intake to the main ECU and I still chose to go back to a carburetor! 😂😂😂

That's right, Eddie is a Texan! God bless him! 💪😎
That is way too cool that you live near him! I met him and his wife in Seattle. Such an awesome guy.

Not only are Eddie Hill & Lloyd Ruby local (Wichita Falls, Texas ) to me but we are also home to Nitrous Express Inc. I have met founder Mike Wood several times. He would probably have some good input to this thread. He is a absolute genius when it comes to fuel induction. I drive by their facility regularly.

I would expect him to be pretty smart with induction if he owns a nitrous company, that's for sure. I know the company but didn't know they were from Wichita Texas. I just saw something the other day about Wichita. Weeeeird. I know he's near Fort Worth but have you ever run into richard Rawlings? Lol. That guy cracks me up. He wears the same style shades that i wear, lol.

 

[scatpack_69]

Richard Rawlings is a bag of shit and doesn’t know anything. Only a money guy

 

[712edf]

I don't know Richard Rawlings.

Wichita Falls is about 90 miles northwest of the greater Ft Worth area. I was born in FW in the 60's.

Mr Wood of Nitrous Express got his start doing testing~ R&D work for another nitrous company over 30 years ago. He also was a drag racer. His family owns several nursing homes in the area & he has done quite well. Wichita Falls has some good motor men.

ZZ Custom Fabrications is located here. He builds custom intake manifolds for Cummins powered puller trucks.

That's cool. Nitrous Express is a great product for sure. I was considering buying the Nitrioue Express system before I bought my NOS system. Boy nitrous is fun! Just make sure your engine has forged pistons, I melted my 383 down one time, I burnt some holes in some pistons, lol. That was a fun learning lesson.

EFI vs Carbs, Umm! The memories. I can remember a time when people would hate on certain carbs and how some of those old carbs didn't like un-level terrain or stalled when you hit a bump. There were fixes, but I can also recall some people converting to propane to get away from carb issues in the world of off road. EFI is far more complex but when it works, it really works well.

The Holley truck avenger is the best carb Ive found for off road, angles are no issue, hard bumps or landings can still slosh enough fuel to cause a stumble though. Propane runs at any angle but doesnt produce as much power as gasoline.

 

[Canadian country boy]

Same with my Thunder AVS carb by Edelbrock. Ive had my truck pointing almost straight down and up and it's never stalled. I also have an electric fuel pump which helps a ton. When I had the cross ram on my Cuda I had dual electric fuel pumps one for each carb and it cured my fuel starvation on hard acceleration problem i was having. I imagine that it keeps the bowls full better.

Ha, that's hilarious. Good video. See, ya never know until you try things. I'll have to read some of the comments, lol.
But here's one thing that is weird about this guy's vapour locking issue, typically a small carb would frost up from a greater venturi effect, no? It seems weird to me for it to heat up so bad.

Earlier I was watching a video of a guy stuffing a small block in to lawn mower. I gotta go find part 2.

I started putzing with computers early, have been known to reverse engineer machine code, do other geeky cool things and paid for my current F everybody existence in part by being slick with them. Ya'd think I'd be the one breaking down doors in EFI ECMs, coming up with ways to swap configs on the fly and generally tune by code. Truth is I really like that the most complex bit of electronics on board is the radio from the 90s. It's kinda why all my drivers are pushing 50 yrs old.

I can appreciate the obvious upsides of fuel economy, emissions, power, etc. I prefer being able to rebuild the whole thing with a phillips and a couple of sockets. More so every time I wrench on one of hers. Spent way too long researching oil filter interchanges for her euro jeep today.
