now the only question that remains for me is:

which one makes the most power 1/4 inch, 3/8 inch, or 1/2 inch?

Knowing
Tony, there is just no way that they would fabicate these results. He
has been a member of these boards for a long time and is highly respected
by me as well as many others.
I second that! Plus, if you did the runs at Churches Automotive, how more independent can you get? Shawn Church is not affiliated with Motodyne at all. I know him personally.

Just to add to the objective nature of the tests, all of the runs were done by Shawn Church himself. He sat in the car for all of the tests, did the work on the keyboard, had the ECU scanner in his other hand, basically was the one man show with the tests. The coolant was warmed up to the same temp. All Hydrazine and I did during that time was stand and watch the numbers on the screen.

It would be physically impossible for me to influence the numbers just standing there. If I could somehow do this, I would have made 300 HP. I know that Shawn has no vested interest in either config. In fact, he was very surprised by how much higher the 3rd gear numbers were compared to the 4th gear ones. He expected a 2-3 HP difference at best. The Crawford is a good product. Hydrazine's spacer is also good. That's why I'm running both now.

I want to do two dynoes with the spacer and Crawford. One back at Church Automotive, and one on the dynojet in Reseda. But I'm looking at $150 for the dynos, and I'm quite broke right now.

I'm not calling BS or trying to bad mouth these guys. I've just been modifying cars for nearly 10 years now and I've got "taken" a few times and believed what I read on the internet. I am a bit of a pessimist....for good reason I hope to God this thing does work as good as the dynos suggest because I'd be much more willing to go with this setup over an aftermarket plenum because it would look factory and it's cheaper plus it might make more power. My primary concern is how well it seals with gaskets on either side. I hope it stays metal because it will be a much better material for trueness.

Any info on how this spacer would work with the kinetix plenum? I have this plenum, either way im going to get the spacer... i have access to a dyno hear on Long Island for fairly cheap, cheaper than anywhere else ive seen, if people in the NY area are down to do some test we can get $50 three-four runs at night time with a group as small as 5 of us.... cheaper with more peole too....

I just havent seen anything discussed about this and the kinetix plenum.... also would a 3/8" spacer fit with the kinetix, if so thats what i want for my group buy....

Sorry, bad choice of words. I meant that there has to be some sort of bias because the two parts are simply serving the same purpose. You might want to try dynoing the stock plenum w/o the spacer vs. the stock plenum w/spacer.

Hi guys,

I said I would post the A/F, so here it is. Also note from the AF plots that the AF results track with the HP results. Hence the results/differences are real. How else could the engine run leaner?...

Yeh, they started a thread on 350z and announced thier own mock spacer made from a stack of gaskets, claiming the joke was on us. It's looking more and more like the joke is on them though =)

Yeah, I saw the thread and your responses.

None of my posts were meant to put down any products. Hydrazine and I planned on also dynoing a stock plenum only and Crawford V5 with spacer, but as I already said, we had to change our plans. It just so happened that the spacer with stock plenum made more power than a Crawford V5. None of us expected that. I can't explain why one config makes more power than a comparable one, all I can do is relay the dyno results, posting all the runs that we did.


The fact that I'm running both the Crawford and the Motordyne spacer speaks well on what I think of both products.

I don't think anyone put down Crawford products at all, they just came out mocking the spacer idea. Like I said in that thread I think they feel very threatened by this new development and are just attempting to discredit it, and are not handling it very professionally. Too bad because they do have some quality products to offer, but so far their business practices are a turn-off for me...

yeah, i kinda read that thread a little........it reminds me of that "we lost another loan to di-tech" commercial!!!.......but in reality, one more name added to the spacer group buy is one less potentially to crawford............i didn't follow their thread that deep, did they back up their "testing" with solid proof(dyno) showing that NO hp was ascertained with that 1/4 stack of gaskets with back to back runs?
