Air to air m62 Eaton supercharger on 5ltr V8

[v8sag]

Has anyone had any experience with one of these?
They have to run upstream of the tb,would I have to ditch the hotwire ecu and run without the afm,any other forseen problems?

Its a common mod to put these (& the smaller M45) on 1.8l mx5's/ miata's.
I had an M45 on my previous car- but I also had a Motec fully programable ecu.
You'll NEED to reposition the TB UPSTREAM of the blower- they don't like positive pressure. You probably find the AFM needs to be there aswell.
Try to keep the downstream volume as small as possible to prevent problems.
ie On the miatas they found a hotside install coupled with larger intercoolers gave pickup & idling problems due to the volume of the chamber between the blower & the inlet manifold.
If I was looking at doing this on an engine of your capacity I'd be looking at the MP 90 (4th gen)
Good luck with the install

why not go air to water and mount it directly under the charger? as long as you have a large enough pre rad there should be no probelms. also will help with packaging, thats as long as you have enough hight.

thanks Chris.

Are you talking about intercoolers, or the supercharger itself? If you keep the boost low you don't need an intercooler, in fact it can do more harm than good. If you're only using an M62 I think you can guaranty that the boost will be low, I think that's far too small for a 5L, it's only 1L displacement so it won't flow more than about what a 4L NA would draw.

I'm talking about the blower itself,I would'nt run intercooler and was wondering about its displacement however I only want enough to give it a bit more poke to lower the diff ratio as I'm running out of puff on the straights.
So if its run upstream of the afm,before it?will I need to map the ecu
I don't know enough about the unit besides them being fairly bulit proof and apparently been run on a few Range rovers without any probs,the price is ok and fabrication wont be an arm and a leg,just need to get more speed fix to the Griff while my never ending progect continues..

Don't think the 62 was used on any range rovers, 90 has been used in some conversions but is marginal on capacity, 112 is what you need. It is literally twice the size so much harder to package though. Impact on the engine management system will be substantial. I would suggest pull through the AFM and throttle, with a vacuum operated recirc valve for cruising. I would advise you not to underestimate the amount of work involved, there are a few people now who have conversions available using a centrefugal blower and these are safer and easier to package so you might want to look at that option - or just save yourself a lot of time and money and go for one of the existing conversions.
