Building a new project and was able to pick up one of these units pretty cheaply and plan to use it on a blow through system. My question is: Does anyone have any experience or words of advice/warning about it?

Thank you to anyone who can help me out, have a Happy Holidays!!

 

don't go cheap on the fuel pump or regulator. still get a 1:1 rrfpr and my suggestion would be aeromotive. top notch products.

i'm not entirely sure how the ecu for that setup will respond with boost, i know it's been done tho. good luck and keep us posted on your results!

 

I helped setup one of the pro-jection D's about 9 years ago when they first came out. so this is probably old news, but the originals used a stock o2 sensor for a/f readings, and we found out that unless you got lucky and got it within the reading range, you were hopelessy lost, an aftermarket wide band is a requirement regardless of what they say in the manual. good luck.

edit: we were setting it up on a chevy 350, which it came with a base map already loaded.

 

I was going to go with a GSL-SE fuel pump for now, if need be I will upgrade to an Aeromotive. The RRFPR I have is a Malpassi from the old Cartech turbo kit I used to have, or I might buy a Mallory 4309. ****, I might have already bought one and can't remember since it's been so long!!

The O2 I will be using is a bung welded universal unit, I am pretty experienced with cars running too rich or too lean so even if the A/F gauge doesn't read I will probably be able to fudge it okay.

Thanks for the suggestions and comments, I really appreciate it!!

 

those will work fine to get you going.

 

I did some research on it and it's ecu has no provision for additional enrichment under boost so you have to run overlly rich under acceleration to compensate. Gas mileage will suck.

 

or be ghetto about it and rock an FMU... ooorrrr rock out methanol injection under boost.

 

My previous setup was a blow through IDF, that didn't have any boost enrichment either. It's not a daily driver so I am not too worried about it, the last one was and the 10 mpg sucked but oh well, it's the price of owning a sports car right?

 

You can get a megasquirt version 2.2 kit for $130 now...

 

But then I would still have to buy fuel rails, injectors, a throttle body and other stuff, the Megasquirt is just a CPU right? Nothing is set in stone just as yet, I still have a Dellorto DHLA sitting here and I REALLY want to do the Weber-style throttle body from TWM with a Haltech F9.

 

Pillage6,

I remember that you PM'ed me a while back about my old Carburator.
I lost all your PM's and information during the move, as I changed PC's etc.

Seeing this post reminded me of your screen name.
Let me know if you still want to try the Holley Carb itself. Just PM me if interested.

 

PM sent.

Does anyone want to buy a Dellorto DHLA and manifold? Will post it in the "for sale" section shortly.

 

holley projection on turbocharged applications work like ****.. better off with directfreaks holley carb!!

 

I thought about this setup many years ago on my first 7. Glad I didn't go through with it.

 

Yeah, that's only for the computer, but it's a complete stand alone system. You'll need add-ons if you want ignition or some easier wiring, but compared to a haltech, it is dirt cheap..
In the end it all depends on your preference and budget, but for me FI is a better long term solution.
If you have a DHLA side draft mani, I believe the DCOE and IDA have the same bolt pattern, in which case, you can just buy a IDA TB and two big injectors to use with your current manifold.. That'd save some cash.

BTW, do you still have your IDF carb hat? I have an IDF throttlebody and wouldn't mind putting together some turbo parts for a conversion down the road...

 

I have a very nice aluminum 40 IDF plenum that is just sitting there, if you want it send me an offer.

The DCOE and DHLA are side drafts, the IDA is a down draft so I don't think they are interchangeable. I PM'ed DirectFreak about his setup which is what I wanted all along, I only decided on alternate systems when he didn't get back to me on it. It's been almost 2 years since I have driven a 7, it's time for my car to live again!!!

Again, thanks for everyone's input, how is business Robert?

 

WTF?!! 2 years since you drove your 7?! thats waaayyy to long!!
business is great, thanks for asking....struggling to keep up with orders, but whats new... lol the worst part is i have no time to work on my own cars, that sucks cheese *****!!
Alex's setup would be sweet on your setup!!

 

I'm not saying the carbs are interchangable. What I mean is that the throttlebodies should be because the bolt pattern is the same.. my bad.

 

Received and replied.

 

The bolt pattern isn't the same. But, you can get DCOE throttle bodies.

 

Thanks for everyone's input, I am going to buy Alex's old setup. I can't wait to get it in, my fingers are shaking in anticipation of turning a key and hearing two little rotors underneath a Holley carb and next to a T76 rumble to life!!

 

get the holley complete jet kit and rock out!!! his jetting may be a bit much, it definitely wont be dead on. but with a little tuning it's gonna be fun as hell!

 

That's what I am thinking, I have an O2 bung welded into the downpipe for easier tuning. I REALLY wanted to go with the throttle body injection but didn't like the $2200 price tag. Alex's setup is way cheaper, easier to install and is almost tuned already.

 

trust me, alex's holley is PERFECT for your setup. you will need a wideband, not a regular o2 air fuel meter. mainly all you should have to do is jet down a bit, probably won't have to mess with the air bleeds or anything else. WOOHOOOO!!!

 

Is it not? Well, my bad again then. I swear I read that someplace. Nevermind..
