Is there any gain from changing the 2wd plenum/elbow over to a 4x4 plenum?

Have read on here before that the elbow on the 2wd is restrictive.

Car is going to be live mapped on greys in April,running T34.63,just wondered if it is worth changing the plenum or is the 2wd plenum/elbow ok for this power level?

Thanks

 

The problem with the 2wd and 4x4 is the distance between trumpets and cover...solution is put a 10mm spacer on.

 

or get a eecv plenum and throttle as its bigger than 4x4 and 2wd

 

Cheers
Got a spacer to fit

Any gain to be got for changing the plenum do you know,or just use the spacer and 2wd plenum???????

 

Changed mine from a 2wd to the 4x4 and got a 8bhp gain with the same boost

Nice one

What did you do with the fuel rail,I noticed the one mounting point is different?

Will need a different fuel regulator then too???
