I'm working on it... The guy that makes them (the Church Auto dyno one) has been sick and not in his shop... I tried to hook up with him last week but he wasn’t in. He is suppose to be back today and I'm waiting to hear from him to go by and possibly get one to test... Tony is doing some track racing so I won’t be able to get together with him for dyno testing till next week hopefully... I'll post results.

In the mean time, whoever has one, post up impressions!

I know - but he hasn't really said anything definitive about performance...

the "swirls" on the inside are (in theory) what helps... if it was just a spacer with smooth inside surface, it definitely won’t do anything... even the "swirls" might not but they did for Shawn Church - so?... you never know...

I would want to see 2 dynos for this from 2 different dynos before I believed it.
you need to read the whole thread... it's all been addressed...

?

Still no answer which way the rifle bore pattern should be facing? Someone should call Shawn and ask him... I'm pretty sure the spacer can be installed either way! I should have mine in a day or two as well.

The rifling “swirls” in a counter-clockwise direction... the tapered end faces the intake manifold/plenum, the wide part of the groove faces the TB. This is directly form the manufacturer (I've met up with him twice)... his concept is to create a funnel effect - I will be testing this with Tony Collette next week... will probably try it both ways for the helluvit.
