Help fitting mantzel inlet
« on: 24 July 2014, 19:55:30 »

Ok so I copied the design for the mantzel power box and now it doesn't fit.

I had no idea there were 2 inlets on the omega, are there 2 designs of the power box?

Here's what I've made, had it all heat wrapped and everything :(





Is it possible to fit the other type of inlet?
FYI the cars a 98 3.0l elite

Thanks pete

My first suggestion is  :-X

My second suggestion is to move it about 18" towards the drivers side in the bottom picture...

Not sure which is more helpful, but beyond the obvious, it's difficult to understand the actual problem :-\

You might also need some silicon plumbing to actually attach it ::)

Yes I'm demonstrating the power box to size of hole in the picture and yes I have all that.

Omegas use 2 inlets, are they interchangeable?

Ah, you mean the plenum...

Yes, but you'll also need the shorter throttle cable(s) and different coolant hoses for the shorter plenum :y

once you start using this , variable length inlet design is gone to the bin..


there are many alternatives in design but that box alone wont give something important..

Dont quiet understand what the pluming problem is, the box is designed to replace the multi ram air flow divider before the throttle bodies, assuming your measurements are correct it should fit.

Needs to fit it to figure that out ::) but should have been about 95mm deep instead of 169mm at a guess ;D

It was probably designed for the short plenum V6. Could swap the plenum, but the short plenums had different throttle position sensor wiring, IIRC, so you might need to make the current throttle work of modify the loom. :-\

Could rotate it forward 90° to fit it, and use the existing ducting to the TB :-\

Then again, could simply not fit it... might work better ::)

I didn't ask for your opinions, if you've got nothing good to say then don't say anything at all

If anyone is genuinely interested this is how it should fit


And as you can see this is not possible with the later design of plenum


I'll swap to the older style short plenum but I guess I'll work that out myself how to do that, nobody on this site seems to understand modifications.

Ooooohohooo now that's totally unfair. My car is much "improved" over the original design. But the thing is, a modification needs to be better than the original remember. :y


Although what's better for me, won't be better for ..... The more comfortable gent. So to speak.

But my point is, that's clearly designed for a short plenum, as said. A modification that's negated by the fact you already have a long plenum, which supersedes that modification anyway. It would be remiss not to mention that the short plenum in conjunction with that box will loose all the low down grunt. But as long as your happy :y

Ffs, use just an ounce of imagination and rotate it forward 90° and use rightangled hoses to fit it to the throttle body :-X

Many of us do modifications, from LPG installs, suspension setup to electrical changes. A mod should improve things, not make it worse.

Longer plenum aided in low down torque on the 3.0 so a lot of time wasted for no improvement.

As said it should fit, but needs to be lower down using right angle hoses from the TB's. If still in doubht have a pm chat with PaulK member on here as he had one ot two made up for his 3.2 from memory. ;)
