4wd plenum
Anyone have an idea as to the level a 2wd plenum becomes restrictive and it's worth changing to the 4wd one. Also I think the small turbo escos one is the best but think it needs a bit of work to get it fitted, my car is planning on being stage 3 at some point and wondered if it was worth the expense to fit one
Thanks

From R&B Motorsport:
The OE inlet manifolds are limited to the following bhp (in the main due to the restrictive elbow NOT the throttle body, which will comfortably flow 650+bhp), 2wd = 430bhp 4x4 = 450bhp EECIV = 500bhp.

Too many posts.. I need a life!!
Dont get a spacer as they only do things worse. You want to lead the air behind the trumpets as it is here the trumpets suck from. The spacer only makes the situation worse, and it makes the engine less responsive as you get more plenumvolume.
I dont think the marginal gain of peak hp using the spacer is worth the price, modify your inlet like mine, or get a proper Hart one if you want to go bigger. The responsive gain on the modified however is HUGE.

Ive got a reyland 14mm spacer on a 4x4 inlet, not sure on how much i gained but it produced 410 lb/ft, imo its worth fitting one as theres definatly a gain in there somewhere. Cheap mod too
