Twin 45 jenvey on xflow

Recommended Posts

Hi guys 

I’ve fitted twin 45 jenvey TB’s onto my xflow engine but I’m having trouble fitting the pipercross air filter as the TB’s sit quite low so the bottom of the filter is sitting on the chassi.

the TB’s are mounted to a 81mmx34mm x 2.5* burton manifold.

i could get the longer manifold but that would only lift the  TB’s up about 12mm which wouldn’t be enough. 

What have you xflow guys go fitted on yours?

forgot to mention the car is a 89 SE model 

thanks in advance 

John

Would raising the engine be an option by inserting a metal plate under the engine mount, my old prelit had this just watch the clearance to the bonnet.

Incidentally if you can post some pics that would be nice and some one else might have better ideas than mine.

What filter are you using? If its a pipercross foam one you can get a blank backing plate that you can then cut it to raise it up.

Here’s a couple of pics to give you a better idea.

Pete, I did think of getting another backplate but thought I might be able to purchase another make of manifold to lift the TBs.

cheers John

I have had this issue a couple of times. Shimming the engine mounts with ally plate or 5mm washers has helped. On the Supercharged Crossflow build we have taken a more extreme approach. Machined  an angle on mounting faces on the inlet manifold.
