M62 Supercharger Specs?

[fmaster7]

How much boost does it put out? And is it safe with milled 95tm heads and the stock bottom end?

I'm not sure of the boost but explorer express uses this blower. I'd say around 6 lbs but it all depends on the pulley you put on the end of it. If you put a smaller pulley then the boost goes up but there's a catch; the intake air temp starts going up (depending on the efficeincy of the blower) and that's what makes it unsafe.

To answer your question, I suggest you do a search for "M62 specs" and see what you come up with. For the second yes It can be done safely on a stock 4.0 but tuning is the key. Same goes for the other blower you posted about.

It would be good information to know how far the heads are milled and the expected compression ratio.

okay sounds good. i dont want too much boost so I wont play with the pulley. im definately getting a custom tune done but not until I get all my stuff together and all the answers to my questions.

I saw a post about this blower that a guy put on his red explorer. It says in the post you have to weld a fitting to the fuel line...do you know why that is?

Thanks Jake

I'm not sure what he welded to his fuel line but it's probably "brazed" and not welded. The only thing I can think of is a fuel pressure gauge but there are other ways other than brazing to the fuel line. If you link me to the post I could tell you what he did.

That thread sounds really sketchy to me.

I'm not sure what the fitting is for but the guy that made the kit appeared to chime in a time or two and said something about using an F150 inline pump and some sort of S-AFC to manipulate the MAF. I don’t like the sounds of that. 1) The MAF should be upgraded and a new tune made; not manipulation tactics which is a band aid and will more than likely give you more troubles. 2) If these OHV explorers have mechanical return less fuel systems, like the one I have with the SOHC, the proper thing to do is drop the tank and upgrade the fuel pump. Using an inline pump, like the kit maker suggested, after the stock pump has regulated in the tank itself is not a good way to keep fuel pressure regulated. There was a post made by Doug904 where he told the right way.

This thread is old and I believe there are much better ways to do this. There is a guy named Turbo Cat that you may PM and ask about the OHV engine but I wouldn't do anything mentioned in that thread. IMHO

well mine has a return to the tank. i think the fitting is for a fuel gauge or something. im going to talk to the owner that supplies the kit for this S/C
