Hi, some came in last December but were immediately sent out to customers so we didn't get a chance to do any testing.
There is quite a big waiting list for them but the next one on the list is being fitted and tested here so I'll let you know the results. We haven't seen any plenum spacer kits that actually work yet, so it'll be quite interesting.
What do you mean by work? As in peak power, area under the curve.
Are you saying that the plenum kits you've tested have made a loss?
Which ones have you tested?
Im sure the Cosworth will make more than the spacers it looks like a decent bit of kit, but just want to know the facts.
We haven't seen any plenum spacers that work at all yet - ie yield any power or torque increase. I'm not sure whether any have actually lost power.
We have not undertaken deliberate testing on every single spacer kit available. We have have only done testing whereby clients have provided the kits themselves and asked us to install and test them.
Hope this helps
Hya what were the results on the kits supplied by customers that you have tested, would be interested to know what the results are especially if there is loss of power as I have a plenum spacer installed,
