Turbo Charging a '94 F350 7.5L

Another question I'd consider:

How long will it take to pay for the modifications being considered? If you spend $2,000 on a turbo setup, custom tune, gears, ect, ect, to improve your fuel mpg by 2 mpg (10 mpg to 12 mpg), it will take 43,000+ miles @ $2.75/gal to break even on the venture. This doesn't account for the potential increase in fuel cost (higher octane?), increased maintenance costs (oil change interval, spark plugs, ect), or the risk of undertaking a project that could ruin a perfectly good engine in a heartbeat.

Have a good day!

I rode with Blake to the Columbus Swap Meet last year in his truck. I've never been so impressed with the way anything ran as I was his truck. That thing is scary fast and the excelleration is just way BADAZZ. You'd never know it was bad at all under normal driving ,but when that thing starts that silly whistling...you'd better be hangin on and pointed the right way.We passed a car on the interstate running about 70 MPH by the time we were around it we were about 110MPH in just a few seconds. That's just a super set up. I was Totally impressed with that SVO (Inside Joke)

Blake,

my buddy put a Turbo on his F-350 dually with a 460 and mounted it underneath the truck.He kept the speed density deal but had some gremblems with it.He wasn't sure if it was from using the speed density setup or the turbo was to small.I you're interested i have some pictures of it on his truck i could e-mail you.He took the setup off his truck and was trying to sell it.

I remember reading years ago where someone put a turbo on a 86 Mustang 5.0 with speed density and ran into a similar problem.
He ended up putting a 1-way vacumm valve near the map sensor.
I assume it was to prevent the map sensor from "seeing" a boost condition but allow the map sensor to work normal under cruising high vacumm conditions.

That one thing has stuck in my head about speed density and boosted engines.

Alan,

He tried different things but don't know if what you mentioned was one of them.I would ask him but i can't get in touch with him,he just went through a stem cell transplant.

Blake,

Pictures sent to both e-mail address's let me know if you got them.

Later Mark.

Your Welcome,Later Mark.
