Eaton M112 Inlet Manifold

topcatcustom · Post by **topcatcustom** » Sat Aug 09, 2008 4:15 pm

Hi, I have a M112 blower that I am going to try and modify to fit on my 3.9 RV8, I also have an Edelbrock Performer inlet manifold.... I don't want to waste it though by doing the wrong thing as I am thinking:

On one hand an offenhouser 360 would be a lot better suited due to its simplicity and design..

On the other hand the EP has excellent design for even distribution to all cylinders which gets over the problem of feeding all cylinders equally!

Anyone help?!?!

not as far as i'm aware - sits on top of the jag engine - injectors are in the manifold.

No it is dry however I have done a bit of homework and it should be fine running wet- and aluminium and teflon are fine with petrol! Really really just hoping there isnt any backfires cos I guess you could say goodbye to the blower then and try and find it afterwards!
I have seen some funny setups like people just making a flange and piping away from the 'charger so my EP should be ok I'm hoping with an adapter plate...

i had the offy 360 modified for a 4-71, when i had the blower freshened up by UK BLOWERS they talked me into using the EP manifold, that they adapted for me.It not only sits lower, it is more powerful

The Eaton wont run wet as the bearings are not sealed.

The petrol will clean them out and it'll sieze within a couple of hundred miles.

I've run an Eaton M112 so have experience of this.

I also still have a prototype manifold which can be used with injection. Sits no higher than the normal plenum but you would need an extra long extension for the M112.

Sealed for life bearings? I know a chap who only does bearings every day...?!
Please say "should be fine"!!!

does 'sealed for life' cover being exposed to volatile erosive petrol though? I have sealed bearings in my DH bike, but i wouldn't put them anywhere near anything that could eat the seals away!

Exactly.

Don't go there with an Eaton, you'll regret it.

I spoke to the chap and he can get sealed bearings with which the seal is neoprene and resistant to pretty much everything.
If the old Wade blowers were common I would use one of those instead! Anyone got a spare?!?!

*There are loads of blowers in the states but shipping costs a fortune!! - only 1 thing for it- move over there!!!

I'm about to bring another consignment of kit in from the USA. If you can get a blower to Chicago I can bring it over for £80

Wow that sounds very tempting- there are a few 4-71 blowers on ebay in the states, how long do I have?!

dont think neoprene is resistant to petrol. Its just not worth the risk.
