Turbo 5.0

[Mercmarquis]

1/2" fuel lines, 42lb injectors? like 5 mpg?

Depends at what duty cycle the injectors are at. Running at 100% duty cycle all the time wont get you any mpg but rather gallons per mile lol. its just at full throttle you want there to be sufficeint fuel flow so you dont starve the motor and blow it up. But if you drive around flooring it everywhere, its gonna eat up a ton of gas no matter what.

instead of expensively and painstakingly tuning the computer, could you not use an AFC hack device, or an FMU to manage air to fuel ratios? I was working on a turbo 1988 acura integra using an APEXi air/fuel controller and it worked great, cheap too.

You might be able to hack the computer with one of those. I wonder if it would be able to work with the larger injectors and upgraded parts, I dont see why it wouldn't be able to tho. Interesting, good idea.

[89LincolnTWNcar]

yeah we upgraded the injectors on the integra too, 450cc instead of 2** stock, and popped on the turbo apparatus, and all that was needed was a bigger fuel pump and that APEXi air/fuel hacker. 180whp in a 2100lb car = fun

how much are they, and do they work with ford eec? hmmm....ricer parts on a ford lol

I'm gonna use the Megasquirt v2 on my car. It has no MAF to mess with, Wide band O2 A/F controll, can use high or low impedance fuel injectors, can use cheaper GM sensors. Also you can control all of your ignition timing and I can use the EDIS-8 No distributor!!! and it even has a rev limiting feature. Its really inexpensive too, around $245 for the kit.

[89LincolnTWNcar]

they are around $250 and they work with any EEEC I'm pretty sure. It just tricks the ECU into adding more fuel via the MAP sensor. It works best on vacuum advance engines which is also good.

you can do it with all the stock components (except for the fuel system), it just will be very sensitive to any error in tuning. For turbo 5.0 info search turbomustangs.com

Got twin tbird turbos on a 302 in a friends turbo tbird. The last few yeres with the Issy turbos are best. The turbo tbirds also have a booster fuel pump in the frame that is needed. We did this set up cheep and dirty it delivers 600 lbs of torq. MAX rpm IS HELD TO 5200 OR SO.

There are ways to do boost with speed density. I don't know for certain how different it is, but I know there was a KB supercharger system for 86-88 Mustangs that did not use mass air. There is a guy on LoL who has a stock Mark VII motor and ECM with a KB running speed density at like 6 psi or something. Not certain there isn't a tune involved with the ECM but I do know it does not have mass air. I imagine if a supercharger can be made to work with it a turbocharger could be fitted in a similar manner.

Thats good to know. Because i dont want to F with the wiring harness. I was thinking of going with a carb that can handle small amout of boost.

A chip tune would be all that is needed to keep the SD setup.

2 255's and 42's? For 400+ HP maybe. You will not see that with a turbo'd lopo. Seriously, go search around turbomustangs for all the info you'll need.

How about one of my boats

[interceptor1985]

Interesting? What is that engine in the boat? It looks like it got two huge turbos! LOL

I dont want to even compute the brainpower into reasoning why u would want to turbo, better yet TWIN turbo a marine engine? most marine equipment run with a consistant rpm..... (ie crusing) then comes the cooling of the inlet charge automobiles use ambient air threw a front mounted intercooler in most cases, im sure there could be some adaptation of a watercooled intercooler as im sure the block is cooled with water is in as most marine engines are

nevermind, a second look at u can see its running open inlet turbos.... duh

thats gotta be one bad ass boat on accelleration

is it running a stern drive? or fully inboard propultion?

Guess you're gonna have a hard time figuring why they run turbo diesels in tractor trailers too, and generators. Turbo's make power under load, and they make lots of torque. Perfect for any situation that require lots of tq and are constantly loaded.
