2wd elbow and plenum right now. there was a small pic of a modded elbow in one of the mags in an article about jenspeed, looked simple enough, but does it work well?

I've modded 2 4x4 plenum elbows but don't have pictures. I also know someone with a modded small turbo escort plenum, again no pictures!

Also need to fit a spacer on there, as std plenum deepth is abit restrictive.


My rs500 inlet with mod's and spacer.

The Plenum was done by Julian Godfrey, for a Rally X car a few years ago, think it most of been flow tested, but i haven't seen any results etc etc.

i did the spacer, and internal 2nd inj bank mods.

...what a pointless exercise ...there is a plenum cover for any power requirement...messing around may increase flow but how many get the fueling checked after!!!!

2wd cover = 440bhp
4x4 cover = 460bhp
eec4 cover = 520bhp
RS500 cover = ???
Swedish plenum = MAXIMUM

..all approx

..dont like the look of Baskys.
