Anyone running one of the new bolt-on all-in-one fuel injection kit?

all of the efi systems will need a high pressure pump.
i know that the fast ezefi has a multiport kit. this means that you can use a factory intake, fuel injectors and all the factory stuff. i would go junkyarding and find an explorer. take the whole intake assembly, throttlebody, injectors, fuel rails, and grab the intake air temp sensor.

 

Theres is a guy on here that has the MSD kit. I think its Mavdog71, not sure though. its a red early grabber that he races a lot. Might be sponsored by MSD or something.

 

Speaking of fuel pumps... I did have an issue with mine overheating and dropping out. This is what spurred my new fuel tank with in-tank pump purchase. Could have been my fuel system routing and/or pump mount location as the route of the problem.

 

glad yours is doing good...
mine...wouldn't hold a tune...it wouldn't go back to the default settings, it would just put any #s in...
replaced it with a new one...same thing...sent it back.
the tech said they must have gotten a batch of bad parts being both were doing the same thing...
...installed the 670 street avenger that I took off my 347...the next morning Effie and I left for the Gathering/Roundup...gone 11 days/2200 miles 21.73 MPG...

 

600 Holley...would do that...

 

I saw the F.A.S.T. multi-port vs the F.A.S.T. CFI in a dyno shootout somewhere in the last year or so. When they were all tuned and running right the multi-port system was ahead about 5-6 HP. I think it was on a Chevy 350 making 400+ HP.

I can't remember where I saw it but I remember making a mental note of it.

 

I read that article too, one of the things they did note that part of the reason they were so close to the horsepower rating was because it was in a canned environment, I mean I hate to say it how much of a real world evironment is a dyno, and 10 min of time on a learning computer...
Where both systems are adaptive the multiport would have ended up with more of a significant difference in both horsepower and fuel economy under real world driving conditions.

But that being said I think most of the kits nowdays are on par with each other, i was really looking at the projection III setups. The original projection I setups have been plauged with quality issues stemming in part from utilizing very cheap offshore manufacturing facilities, and in part from a new product for a small(comparitively) company..

But hands down I would probably stick with either the MSD or the F.A.S.T system if I was buying one of those systems.

MSD has allot broader knowledge base, and are able to utilize all the data they have available from both their superchips division and the Edge products division...so yeah they have been making tuners for years. And most of us know and love their Ignition systems.

F.A.S.T is a division of the Comp Cams performance group, they have allot of knowledge in making obscene ammounts of power and have advanced the bolt on EFI kits allot. They also have a good knowledge base with the Inglese fuel division and do allot of performance fuel systems in accordance with those setups.

 

What about doing your own???
Take a -cough - cough GM throttle body; adapter plate; and I dont remember the specifics for the computer but the guy i knew used one from a G-20 van with a 350 I think - but it worked pretty well i dont remember if it used or if he used a spark input for it....it was on a fairly stock 351 in a pick up truck... JM

 

I was going to go with the Powerjection III for the simple fact that it's the only one of the bunch that can deal with boost. I was thinking of supercharging later on and it's MAP can go to 21 PSI. I would only go 5-7 PSI of course Also it only requires a bonnet for the TB entry. Not a whole box, because the TB assembly is sealed.

Also. I talked to the guy there (Bryce I think) and he said the aluminum components are made over seas and the electronic stuff is made here.

 

Thanks for bringing that up about boost! I would also like to boost in the future. I also asked an MSD rep about if the program can handle nitrous, and he said they are in the process of creating a program you can flash into the computer to handle it, but they haven't finished it yet.

My problem is that I have had bad luck with FAST products in the past, and it leaves a bad feeling that will be hard to overcome.

But, to give them credit, they spent a good deal of time on the phone with me after they realized I was "fairly" technically adept. We ran several electrical tests and determined that one part was faulty, and they quickly sent me a replacement.

It works now, so I guess the outcome was positive.

Better customer support than you get for 95% of the products we buy nowadays.

 

I say go with a holley hp series efi..onlythings you need to buy on top of the kit would be distributor harness and injectors

for fuel delivery cant beat a fuelab prodigy pump paired upwith their electronic fpr!(can control 2 pumps)

 

btw, check around on buys ofthe powerjection 3..ive exchanged minetrhough summit over it

need to modd the throttleblades, i think it was..prettymuch having the same problems as a carb such as cold start issues and so on..though I think they may have solvedeverything by now

For about the best thread on the pjIII forproblems,fixes/tunning fixes here you go. definatly a must read before you purchase and also after for tuning!
