EFI Options

[rspears]

We've talked quite a bit here about some of the new self tuning throttle body EFI units, the kind that resemble a 4-barrel carburetor and bolt on to your existing manifold. If you're thinking of making the investment in one, like the Holley HP EFI, the FAST EZ EFI, or the MSD Atomic EFI you might want to cool your jets for a bit and take a look at Edelbrock's new E Street package. It's had over a year of development, and it will take the self tune function to a whole new level, giving the best of the self learning with features that allow human interface to over ride the computer when needed. Looks like a cool new deal that may be raising the bar again. http://www.edelbrock.com/automotive_...et_intro.shtml

Roger.What kind of money are they getting for those??. Is there a hp range for them??.

[1gary]

I forgot to ask if there is a camshaft limitation like for the lobe centers needing to be 112 or better for tuning??.

there are probably efi stuff for about any make/model engine out there and you probably otta take a look at oem type stuff----might be a lot cheaper to do and you can find parts for them at any dealership if your on the road away from home---------keep in mind that any of them will require O2 sensors, higher level of temp control(both coolant and intake temp), some type of trigger and throttle position sensors, MAP,MAF and rpm/speed, especially with automatic trans and lockup converters-----also a higher pressure fuel supply system--------

I personally would stay away from the carb type throttle body systems UNLESS they have sequential injectors located in the ports , not at the throttle body location..

Yes on the O2 sensor, Jerry, as well as the higher capacity fuel pump. The TPS, MAP, MAF and air temp are all built into the body with no extra wiring. Not sure if they provide a dedicated coolant sensor for input to their ECU or not (probably). For a high performance application I agree that multi-port injection is definitely better, but for the run of the mill street rod that sees an occasional WOT for play, but mostly is cruising around I think these throttle body systems are a great replacement for a carb. Great tuning across the power band, good economy, and easy to install.

I'm not an Edelbrock rep and only heard about this new product today when I was talking to my Edelbrock guy about how correction curves work together. I'm just pointing out that another player has entered the game with the other "quick EFI" systems, and it appears they are raising the bar for the market with some improved tuning options and tuning accuracy. Any application questions go back to their website, or call their product sales lines as advertised.

Good write up on it on the Edelbrock site, lots of good information!!! I like to see more companies coming out with EFI stuff, the competition certainly seems to raise the quality of everyone's offering!!!!

[1gary]

I'm always curious about these systems. Not sure what Dave is talking about for a write up. I'll go back to their web site and take a peek.

and this is a link to the setup I keep dreaming about for the '57!!!!!!!!!

WARNING!!!!! Don't look, it's really nice!!!!!

Hilborn Fuel Injectors

Ok, you were warned!!!

[jerry clayton]

Edelbrock has had a system out for many years---left a lot to be desired

The Hilborn electronic----what I put on the 32 ford in my gallery for a customer---what , maybe 7 or 8 years ago?????

Traced a ref link to Edelbrock's forum where the ref link to Jeg's stated a cost of $2,184.99 is.The Jeg's link was removed from their site.

Yup, I put one of the old units on a customer's car about the same time. Lots of problems!!! They have new and greatly improved electronics now, local dude put one on a SBC this summer, runs great!

[jerry clayton]

Corey just stopped by to pick up his dogs--they dynoed/tuned a new Camaro ZL1 today that they had changed cam, ported the heads, blower and throttle body plus 2 in headers/exhaust---709 hp to the wheels and idles---

[Dave Severson]

Wow!!!! great big number for a bit of work!!!! It will probably still get decent fuel mileage, too!!!!!!!

With EFI throwing anybody out based on what they were doing seven or eight years back is pretty hard to justify. The whole world of electronics and computer controls is evolving so fast that systems change on a regular basis. The beauty of dealing with a company like Edelbrock is that they have techs who are in the trenches twisting wrenches on real cars, not just desk jockeys pushing theory. I've had some struggles with my ProFlow XT system, but they were mainly me not understanding the system, or overlooking corrections that are now obvious to me. I've got nothing on the line with Edelbrock, or any other supplier. I'm just pointing out that they have been looking at all of the systems out there now, assessing shortcomings and strengths based on owner feedback, and have developed theirs to springboard off of that experience. If I were building another one today and needed a total induction system I would likely be looking to Edelbrock.

Dave, that Hilborn system is killer in the looks department. I talked to a guy at the Arizona Good Guys that was running the Inglese system with the tall stacks - looks similar, but not as sexy as the Hilborn. I will say that they seem to be pretty proud of those units!!

Yeah, they are spendy-=---which is why I'll probably just keep dreaming about it and run either the Edelbrock or Fast intake!!!!!!!
