BLOWN FUEL INJECTION DISCUSSION

[Blown70]

So, I am interested in the knowledge of EFI and Superchargers.

I am told mechanical Injection is only for idle or wide open and therefore NOT a good Idea for the street.

Speaking to MEW (rick, or rich?) states the enderle injection is good but the fuel mapping can be short exp on the 16 nozzle set up.   He would recommend 8.   However still states that A LOT of tuning would need to take place. Carbs would be better.

Now I can get the injected look from ALSBLOWERS.com   But you still have the height of the carbs and there SC520 scoop.   (which is the one I like with the Barndoor opening.)

So RON...... time to spill your knowledge of Blown fuel injection.   Keep in mind I have spoken to several people.   BDS has the Fuel injection for about what $7,000?

Second question..... Best supercharger.   Everyone hands down told me the BEST was Littlefield..... BDS was ok but not the best?

Lastly the motor this is going on will be a big # hemi.   528 or so.   I was also told to run a 10/71.

THOUGHTS.....Anyone with some knowledge feel free to respond.

That sounds like quite the project ! I've got no experience on fuel injected blower applications....only what i've read. The one name that keeps popping up is FAST and those units seem to be the hot ticket these days. There's a member here that just built a big stroker blown hemi with a FAST efi system and he could probably walk you through it better than i could. His name is Johnathon and his handle is : Eastcoastchargers. He doesn't post much in the tech section but you could send him a pm for more info.

My experience has been limited to carburated roots type applications. My friend has a Dyers 6-71 on his Bulldog headed 440 and seems satisfied so far. The new combo is still being dialed in and it uses modified 850 cfm double pumpers. BDS is reputed to be a good source for blowers....haven't heard much negative about them.

Inmo, the blower business that you decide to buy from will be your best source of information...they'll have a good idea what works and what doesn't. I wish there was something more i could tell you but i won't speculate on something i haven't wrenched on...that wouldn't be fair to you. I should read more on this stuff but i've had good success doing it the old school way using carbs. There's no doubt fuel injection is superior, just look at new car technology....carbs are long gone, lol !

Here's a link to the FAST efi website:

Good luck with it....sounds like a killer project !

Personally, I'm a big fan of MegaSquirt - www.msefi.com for forums, www.megasquirt.info for info.   The current iteration of the board has amazing capacity.   Not even a consideration if you don't want to do it yourself, though
The coolest thing about it is scalability, though; the fact that you can custom set all the maps (including the range of those maps) means that you can use it for NA tuning with great detail, then scale the map up to handle boosted readings as well.   Looking at the FAST system web site, the MS can do nearly everything listed.   The only capacity difference is that FAST can do individual port tuning, where MS is restricted to only batch-fire port injection.   Still, that's not going to make more than a few HP difference at the most, and when you compare the prices... whew.   MS can be had for around $350 professionally built, much less if you build it yourself...   I found a FAST controller on sale on one site for $2150!
Of course, the MS requires hand-configuring many of the options, so it's definitely more difficult.   But on the other hand, when you're done, you'll know your setup ABSOLUTELY, no question there...   As for performance, I'll let you know when I get mine - which is in the process of having a manifold machined to switch it from throttle body injection to port - off the dyno in a few weeks

 Blowen 70, what kind of power are you looking for?    If what I have been told about my money pit right I have more power than I want. Just a 440 and a big bore 6-71 GMC blower and mild blower cam. If Ray is close on the power mine will be around 789 foot pound and 300 HP at 2000 RPM, 600 foot pounds and 685 HP at 5200 RPM's. I was hoping for 575 to 600 HP so even if Ray is hight will meet my needs.

Two tips I will give you. Forget what you think you know about engines when you go with a Blower. I have learned more in the last 2 years than I have in the last 15. Buy all your parts from one vendor. I wasted around $500.00 trying to save $200.00.

Here are a few numbers for you. Leo's Supercharger's. Leo bulit my GMC 6-71 and gives a life time warrty on the blower's he bulids. Does the blower's to support his gear head habits. 636-227-7684 he will have a blower that will make no matter how much power you want. He is also a BDS out let. If you call him just tell him the Ken with the red 69 Charger sent you, would not know who Cuda Ken is.

Reed Cam's, ask for Dennis. Dennis is Douchebag from the old site. He is the engine bulider for Reed Cam's and set me up with my cam. Reed Cam's number is 770-474-6664. Dennis will know who Cuda Ken is.

Eastcost Charger would be a good person to talk to as well. I thought he went with the BDS injection.

      Good luck and hang on tight, Cuda Ken.

 Few PIC 1 of my money pit before it was in the Charger, Eastcoast injection set up and Leo's shop. Mine is in the center of the PIC on a stand.

WOW great discussion.... I will be doing some reading now.  Keep going gents.

Also, I really dont care about the horse but I would like this to be pretty mean.....

[Blown70]

Does Fast have to deal with the rails?   I like the look, yes I am picky, of this motor.  I spoke with MEW about this and he said 16 lines was a bit much but a 8 line system would have worked much better.  Flow wise however he also said tuning would have to be done on the dyno and still have to tune of course more in the car.

[cudaken]

 Blowen 70, you need to thaink about a couple of things.

How much you want to spend, the stroker Hemi will cost more than my whole 440.

Cost of support gear, that where I am. Have the motor, but need support gear. Tran's, drive shaft, rear end, rear suspension, roll cage so I don't bend the Charger. For my Charger to do what it could I will need another $8,000.00.

I did mine as a driver, so I dont care what the ET is as long as it will do a 13.0. With what you are talking about there is well over 1500 HP and I don't think a 528 Hemi bottom end will handel that kind of power. That is why I stopped where I did, 700 HP is the max a stock casting 440 will take for a while. I have good stuff in the block APR everthing, shoot peened, polished and all the happy stuff. If, I run her hard I will blow the main webs out of the block. On a carb she would spin 7000 RPM's for a long time.

If you are looking for cool, I have that.

Ken,

The only reason I am going this route is my charger is HIGHLY modified.   I will try to attach a pic here.   She has a DANA and will have a back pressure cover for the mains on the rear.

Part of this discussion is to find out just what I am looking at,   I plan on using a KB alum water block so it should stand up to the HP.  I will need to get the heads first as I want to clean up the firewall here.  I have A LOT OF work to do.  But Most of the car part is done.  She has a Alston 4 link in already

[cudaken]

 When I saw the PIC of the Hemi you posted I knew that was a KB. Looks like your are up to handel the HP unlike me. I have a friend that races a KB Hemi that is injected in a Wileys. Leo did his blower set up. It is race and he uses a Brid Catcher that Leo did. If you like his number I will call him and see if it would be OK to send you his number.

Hey Tom, glad you getting to work on her some. As far as the FI goes, get a hold of Jonathan(eastcoastcharger). He just bolted on a FAST system with a 8-71 BDS blower. He said it is very streetable.
I seen it in person a couple weeks ago, its a killer setup. Heres a pic.

[Blown70]

Yes it is nice to finally get to some of this.   I have changed my mind about the 440 so now I am going to do what I had wanted and run the hemi.   However that means I have to change some things.   I plan on doing alot of the metal work this winter.  

I need to learn about a few things prior.   I did find a new lid for her down the road a guy has a clean no dent roof I am going to swap on to her.

I will have to get a hold of johnathan   I spoke with his wife via PM,,,,

Nice car Blown....that's gonna be one sweet ride. Luv what you've done so far. I agree on the hemi...if any motor was made to be blown it's a hemi. That hemispherical combustion chamber is perfect for forced induction.

Ron, some of this was done prior to me purchasing it.  I traded some cars to get this the guy was going to drag the car.  But, found out a 440 could only handle so much horse.  Thus I now have it.  I DO need to change the front end, if you look those coil over struts will not handle street driving.  I plan on going with an Alston front end on it....  Yes I have a lot of work. But nothing better to do in the winter...LOL

did you ever get your blown HEMI and the 1500Hp you wanted for the street?
