It's post #12 in your forum. Scroll down and read it. Surely you are capable of taking responsibility for your own postings, no?

I don't know/care who you PM'ed it to, it was read in its entirety here, post #12:

https://g35driver.com/forums/florida-g-club/48134-time-another-cfl-dyno-day.html

You have officially gone off of the deep end. You are now making things up from whole cloth. Read what you posted here, and then re-think your above statements.

Adieu, Neff.

Those pulls helped to warm up the engine oil... My guess is that the spacer was then added and then the car was dynoed another 5+ times to get the car good and hot and this lead to the spacer showing the "great results". (This is just a hunch and I could be wrong, but after reading the comments in their posts, this seems reasonable to me).

....
Since this was posted on a public forum, I'll address this.

Here's exactly what occurred that day for the dyno testing at Church Automotive.

Tony and I met up at Church Automotive. It was the first time we had met each other in person.

My car gets the wheels taken off, and is set up on the dyno. This is done by Shaun, the shop owner.

I was already running the Crawford V5 plenum (CV5), so it makes sense to dyno that setup first.

First 3 runs are done with CV5 in 4th gear (5AT coupe). All the runs are performed by the shop owner sitting in my car. He's got the OBDII scanner in one hand, the keyboard for the computer in another. His routine is to run at the same coolant temps (I forgot the exact temp). The numbers are about 257-260. I had specifically requested 4th gear runs since my previous runs at that shop were in 4th.

We then do 3rd gear runs. Unfortunately, Shaun forgot to save the 4th gear run data, so I don't have those. We do 4 runs. The numbers have been posted several times. BTW, the numbers were 267.15, 270.18, 267.96. In that order of running too, so the numbers did not show a simple increasing trend. This is going off my plot, and I didn't plot the 4th run, because it was essentially the same stuff.

Tony and I take off the CV5 and put on a 1/4" spacer with stock plenum. We take about 30 minutes to do this, while Shaun takes care of other stuff in the shop. The car is still on the dyno machine, and hasn't moved.

We do about 4-5 runs with the spacer. Again, the numbers have been published. Again, Shaun is doing all the dyno runs. Tony and I are just standing there looking at the computer monitor. We didn't toss out low numbers. The very first run with the spacer is 275.83, then the next is 273.99, then 274.48. I didn't plot every single run, since the graph would be too hard to read, but the numbers did not show an increasing or decreasing trend with a given setup. Again, the complete Excel file with data from every single run is available to anyone on request.

We then take off the spacer and stock plenum, but notice that my lower plenum bolt threads are starting to strip. We leave the spacer there, add the CV5 on top of it, and take my car off the dyno. I drive home that night noticing that the car definitely feels stronger with the spacer.

I typed all this out to set straight the events that day, so people don't go off a "hunch." I had already bought the Crawford, there's no reason why I would want it to do worse than the spacer. But now I'm running both, so life's good.

I give up!

I've gone in a tailspin and cannot get out of this one. I've stood behind my own opinions/convictions and the information that I've received. Without this data being published, I only have my own opinions and I've pushed them as fact.

What to do now?
Delete all of my posts and pretend this never happened? Not fair to everyone else.
Continue to take a beating for Doug when he could easily come on here and help clear a few things up? Not going to happen.
Do I still not like the fact that Tony stated that his plenums "balanced air flow"? Yes.
Have I said more than enough negative things towards him and the rest of you to more than make up for it? Unfortunately, yes.

All I can do now is tuck my tail between my legs and take the lashing that I rightfully deserve.

Unfortunately a very good point about 2 good products both making the same claim, when only one of them can actually do what they claim will be lost in the shuffle. That's all my fault so I'll have to live with this.

So, to anyone I've personally attacked or offended, "I'M SORRY". If a "blanket apology" isn't good enough, send me a PM with a "you owe me" in the title and I'll send you a personal well written apology. You can then post that if you like in the public forum but that's all I can do at this point.

So... where do we go from here?

How about we just enjoy our cars and the mods we've chosen to add (for whatever reason)???

Thanks for at least editing out the (undeserved) insults towards me about allegedly posting your PM.

I love revisionist history.

I was in the process of editing and deleting all of my posts when I realized that this was not right. Realizing this was not fair, I immediately stopped. I then went to where the post was made (where you found it) and added in some verbage to the fact that I screwed up and "I'll have to take my lumps like a man". Unfortunately I had already edited the post you're referring to so I thought this would be the best way to handle the situation from that point forward. I will not, out of principle, delete or edit anything else that I've said. I'd really like to edit/delete a few statements, but it will serve absolutely no purpose at this point.

Apology stands.

Even posting flow data from both sides will not solve anything, there are too many variables at work. Besides, I doubt Doug would even show up here anyway, they seem to have some sort of a God complex over there on My350 and apparently we lowly G35'ers are just not relevant enough to them. They have basically admitted as much in one of the threads over there.

What we need is an independent dyno shootout on a virtually stock car, and make sure there are also reps from each side that can inspect/do the installs in between runs, making sure all things are fair and equal.

Yea sure, in the end I couldn't really care less which one makes a couple more HP or TQ, because I am happy with the spacer, but it's fun competition and we will all learn something in the process. This is how product designs improve which benefits the consumers.

I think it's shootout time!!!

LOL. PURE COMEDY. this is funnier than dave chappelle or southpark...well not southpark, but dave chappelle...some episodes.

Seriously though, i think most of what i read of what NEFF has said adds to much advertising for Tony. LOL. everyone hates the crawford cheerleaders on my350z (dunno if its everyone, but its me, so to me thats everyone LOL) and everytime they post, people go and buy other people's stuff.

so i come to conclude that NEFF and TONY are working together!!! LOL. that must be the answer. AHAHAAA

Guys, hold on here this is getting way overheated for just a bunch of parts.
Todd has been repeating some of what we have discussed between him and myself. But be clear on this we are not knocking anybody’s parts just saying in or testing we found a 30 percent flow differential between the ft and rear intake runners with the stock plenum. We tried all kinds of solutions, we did look at spacers but to satisfy the flow difference we found the plenum idea to be most beneficial. We now have a 0 percent drop to the ft cylinders. Again please don’t think for a minute we are out to downgrade anybody else’s ideas or parts. We are all in this together trying to find the best bang for the buck solution out there for these cars and we are truly sorry for offending anyone. That said I think everyone will benefit from these discussions so lets not get all heated and bent out of shape. If anybody has ideas or just wants to chat call me. The number is on the web site.

Doug

Thanks Doug for chiming in. Also thanks to Dizz, Copbait, Tony and tazdevl for accepting my apologies.

One good thing came out of this (even though I made an **** out of myself in the process) I did get a nice PM from Hydrazine that stated...

The cool thing is the plenum "allegedly" balances the air flow (by Doug's claims) perfectly and the spacer "gets close" (by Tony's claims). This was the argument I was pathetically trying to make earlier, and now that he dust is settled (don't worry I'm not going to say it), looks like the answer prevailed, sort of.

I'm sure both products are good, I guess it just boils down to whether you want to pay $395 for the Cast Crawford Plenum or save a hundred dollars or so and get the Motordyne 1/2" Plenum Spacer. Kind of depends on your priorities and your end goals I guess.

Tony- how's that for a "fair and objective" post?

It's all gravy baby.

I hope your dyno day goes well.
