Who has the most adanced system out there on a Buick??? The Blackhawk system is surely built from parts that would be available to any of us providing they are affordable. Just wondering what anyone has tried. Once the injection is mastered it would be easy to talk blower and then variable cam timing????? ED
The EFI is very do-able, you just have to do it yourself! (or pay someone else) The biggies are having the intake modified for the injectors, adapting a crank trigger and adding a cam trigger (if you go sequential). The cam trigger can be adapted to the distributor. A billet throttle body with a throttle position sensor can be bolted on in place of the carb, and the sensors are just as easy. The fuel pump and filter, EFI control unit and wiring, regulator, etc are almost bolt on (after you drill holes!). Setting up the EFI unit is best left to the experts (I'm not one, yet!) but keep your nose over their shoulder to learn it yourself. A kit would make it eaiser and maybe even a week-end bolt on, but there are no major roadblocks keeping EFI away from the older Buicks! I collected parts for a year before I even installed the system! http://www.thedinosaurgang.com/grnsheet.htm
TA PERF has a picture of port fuel injection on there website no cost or anything shown but it says availiable hope this helps
Hi Guys, Ed........I agree with Alan on all these points! When I get this all together and the bugs worked out, brackets made and properly fitted I MAY offer a complete bolt on kit in the next year or so. Here is what my EFI'd Kenne-Bell Wildcat "Cool Runner" intake looks like so far......
Can someone explain why/how the crank trigger works with the injection? I know what a crank trigger is with respect to ignition, but how's it hook to the injection? I'm guessing the computer senses when to inject and where based on crank position. Kerry, What are you using? How did the early (57 Chevy) injection work?
Well, the way it is on the GN/TR's, the crank sensor tells the ecm where TDC for #1 is...The cam sensor on the GN/TR's is then set to 25* ATDC to tell the ecm when to fire the #6 inj(which is the next cyl. in the firing order)...From there, it just fires the injs sequentially through the firing order...On the 3.8L V6, the firing order is 1 6 5 4 3 2...Now, a V8 will probably have a different initial cam sensor setting(or other type of cam sensor trigger) since the 78-87 3.8L V6 has a split-throw, even-fire crank(meaning each rod has it's own journal, not a shared journal like the V8s and the 77 and earlier odd-fire Buick V6s)... Had to learn this crap to be able to troubleshoot the system when things don't always work out right... o No: Hope this helps out some...
Hi! What should I think of when choosing a manifold to convert to EFI? Is there any reason not to use a single plane intake when adding fuel in the port? The offenhauser 360 intake is cheap on the market, is this because of poor/unequal flow or problems with unequal fuel/air mixture? /Torbjrn
I started using a port FI system in the fall of '99 and love it! Before that I used a TBI system (the infamous Holley Projection) and it is okay, for the money, but now that I have a modern system I'm never looking back! I used the TA manifold and sent it to Force Fuel Injection (www.force-efi.com) in Florida. They did a great job of assembling the whole kit- they install the injectors, plumb the fuel rails, and provide a complete system (fuel pump, regulator, etc.). They also provided me with the SpeedPro controller (now called F.A.S.T.), and that thing RULES! It doesn't require a crank sensor (unless you go with the sequential setup, a waste of money IMO), it just works off of the distributor. (Sidebar: The function of a cam sensor is to tell the ECU where the engine is. Normally the ECU just reads the distributor pickup to tell it where the engine is, but there is no reference for the #1 cylinder so a cam sensor will tell the ECU when your at cylinder #1 so it can sync the injection. If you use a bank-to-bank injection system, which is all you really need anyhow, the ECU doesn't care where the #1 cylinder is in rotation.) From what I understand, my system is essentially the same as on the Blackhawk. Tuning is a piece of cake- just let me at your car for a few hours and I'll have it running like a charm! (as long as you use the FAST controller) Or, with Force, you can always call them for tech help, they are very knowledageble and helpful. I also use my FI system with nitrous, and the FAST system will control that too (including automatically retarding timing, making your A/F ratio richer, or whatever). -Bob Cunningham bobc@gnttype.org
Bob, How much (if you don't mind sharing) did the system cost? I just talked to someone that told me that TA is listing their system for $4000. I don't know what controller they are using, but assume it is the FAST. By the way, good to see you signed up. You knowledge and input here is valuable.
Hey, Adam- I think my check to Force was about $4,300. On top of that I had to buy some fuel lines, fittings, re-plumb my nitrous system, etc., so total cost for the project was right around $5,000. And in theory add to that the cost of the manifold, I sent them my TA manifold. I think that TA uses a different controller- I would definately go with the FAST using a wide-band oxygen sensor. My best time prior to this FI system was a 13.38 @ 104, first weekend out with the FI system I ran 12.79@110. Pretty amazing! And on the way to BG last year I measured 19.6 miles/gallon when I was driving it nicely. -Bob Cunningham bobc@gnttype.org
:eek2: :eek2: :eek2: Pretty amazing,,, I'll say!!! What were you running before the FI setup??? A 2V ??? That's an incredible performance improvement, just from adding an FI system!!!!! Not to mention a, what,,, 5 mpg improvement??!!??!! Wow!
Darryl- Before I went to this system, I had the Holley ProJection, which I'd been running since '93. I'd tuned that thing pretty good, and was very surprised at the difference that the new setup made. Unfortunately I don't have a carbeurated baseline for reference. However, I've heard that in the GN crowd, a 1/2 second gain out of the box is not uncommon. -Bob C. bobc@gnttype.org
