dont know if this has been addressed yet, but does anyone have any ideas on why the kinetix plenum has made created signifigant gains across the board whereas the crawford showed only a 4 hp gain at the top end? i would have thought that the crawford design with its larger size (no room for STB) would have allowed more airflow compared to the kinetix one. albiet all of the dynos have been on cars already modified and not stock, this is an interesting turn of events.

 

wait for more tests my friend..... dynos that is.... i am not a loyal crawford fan, nor do i own any of there parts, but from what i have seen and followed only the last independent dyno showed such poos gains, and imo the whole thing seems a little shady.....

thats obviously not the only indepentdent dyno though .... just a few days before 350_danny? took the crawford plenum to the dyno and made 10 peak hp and 17 at redline....... almost better then claimed by Crawford.......

im not buying either anytime soon... gonna sit back and watch everything unfold.....

 

i believe the dyno that showed only 4rwhp gain is not valid. well in my book anyways.

 

this would be a very hard question to answer with pure speculation at this point....so if it works, who really cares about why...not me....just go with it...

 

I am thinking that people are basing this off of only 2 of the latest dynos, with different cars, different machines, different mods, etc.....I would bet that even LSD would disagree with the outcome of the latest Crawford dyno, but he sure isn't going to put out a fire that he didn't set. Time will tell.

 

Eventually, someone with a completely stock car will dyno with both the Crawford and the Kinetix plenums. These dyno results should put things into proper perspective and show what each of these plenums can do on their own with regard to HP and torque gains as well as A/F readings.

Following that, a test of each plenum with their company's respective High Flow Cats would show what the "package" can do.

Both companies (Crawford and Kinetix) should at this point be applauded for their pioneering spirit and for the innovations they have achieved thus far.

 

well said, and agreed!!!!!

 

I also agree.....This Crawford...Kinetix.....thing is getting stupid......My daddy can beat up your daddy...thing.....Only way to do it is...to compare both on the same car..same Dyno..same day....by people that dont have connections to either

 

Hooray...are these the voices of reason shouting out above the din of the throng?

 

I would be happy to do that. I'm running a dyno day, and if I can work it out with LSD, maybe I can get him to throw me over one of the final prototype Kinetix plenums. Cost would be minimal to me, but no promises. It's alot of work going from stock to Kinetix to Crawford on a warm engine.

Perhaps Sport Z Magazine could conduct a PLENUM SHOOTOUT?!?!?

Crawford Vs. Kinetix Racing, Vs. Esprit

 

Does anybody else out there realize how great this is for everybody without a plenum?! Since Kinetix released a plenum that made Big gains, we have competition on the market thus prices will continue to get better and both crawford and kinetix will have to continue to get better and better. Good news for us!

 

Then everyone has to wait 3 months for the results and they have to buy Sport Z.

 

Different cars, different dyno's, different days, different flow patterns, different plenum material.....

Also, your example is of only one Crawford dyno (of which there are many). Some of the other crawford dynos have shown gains similar to that of the Kinetix dyno.

These dyno's are a very good example of why it is so difficult to quantify gains from mods. There are so many variables that it is extremely difficult to get an accurate portrayal of how each mod affects each car.

So, I don't find this surprising at all. Each dyno is simply another data point that can be used in determining an average gain and weighing a purchasing decision.

Plus the b!tch-fests are quite entertaining (at least for an outsider - probably not so much fun for those involved)

-D'oh!

 

Not fun at all. Don't know how I got so involved in the mix, and all I did was volunteer my car and my time. In light of all this mess, hopefully some lurking new Z owners may volunteer their time and effort on their stock Z's to show us some more numbers to study. But those are high hopes, because many have probably been scared off.

Hey, at least we've got some cool choices now, and our Z's are only getting faster and faster. Hopefully soon our competitive nature will turn towards getting the win at a race or an improved track time instead of brand loyalty concerns.

 

also do not forget that my baseline was done with a set of brand new hi-flow cats.

I honestly think the cats (with another week to loosen up) did a little something to help my dyno numbers with the plenum. AND, when you look at the last dyno, sae corrected, smoothed to 3(what ever that does) shows the dyno gains lower, still nice but less. On a good note, by adding cats and plenum I jumped 17 rwhp!


here is that last dyno so you do not have to jump over to find it (if interested)

 

Thanks all_bark. You did a great job on getting this done. I know that it was not easy to do and required a lot of effort, money and personal time. I for one, am convinced that you did a totally neutral and honest assesment of the product. You told us what went right and you told us what went wrong. You reported fully on the gains shown and I know that had the gains been disappointing, you would have reported just as fully on that outcome as well.

I very much appreciate your efforts......Ya Done Good!

 

Well, I believe that both the crawford and kinetix products would put up similar results in similar environments. As for the plenums, kinetix is probably lighter cause it is plastic. But the biggest difference is the price, and that difference is real hard to ignore.

 

Has the price for the Kinetix been released? I must have missed it in all these threads if it has. At any rate, if it is priced competitively with the Crawford, the biggest draw is that you get to keep your stock plenum.

 

One of the first threads on the plenum said it would be less than 400 dollars. How much less I do not know.
