Small turbo Escos I think mate. Or RS500, depending on the depth of your pockets.

JonnyBravo

Best for what ?

2wd is good upto 400 ish iirc 4wd upto 450, eec4 upto 500.

I think Rod is still running the RS500 one on his engine isn't he ?

Yes RS500 with 14mm spacer good for 750bhp+

JonnyBravo

Did you ever dyno it with the MIS manifold on ? What was Marks opinion on that over what your using ?

Does a RS500 plenum have much in the way of gains over a much cheaper option of a 'swedish' style plenum?

Rod-Tarry

Yes & No.

No direct comparison was made but Daves info & mine on the GT35 were compared & the RS500 made Power earlier. 500bhp @ 1.3 bar whereas the MIS needed 1.7 bar. Up to 770bhp it appears to have no advantages over the Spaced RS500 in fact I suggest its inferior, looks good though.
