Anybody fi running the kinetixs velocity manifold? What do you think. It feels like it defiantly pulls harder after 5500 rpms. I know it has threads already but most of the talk is na and not much fi

 

I own the kinetix as do several friends.
So, four things that I can tell you, and it's about the best I can offer:

1. I like mine
2. My friends like theirs
3. I can't speak to the power differences between the cosworth, kinetix, or just a plain plenum spacer... but our cars make good power. Mine is 402whp on 9psi procharger, a friend with a 9psi vortech has longtubes, the kinetix and exhaust, puts down 454whp, and several other turbo guys I know have it and make good power.
4. They crack. Often.

Good luck to you, kind sir, on your quest for knowledge.

 

#4 is a deal buster for me..
at only 9psi, having a cracking plenum is unnaceptable for this guy.

I imagine ill be upwards of 15-20psi. Sticking w stock n a spacer.

 

It is for most people, as it should be. Haven't cracked mine yet. But I know three people that have cracked theirs. One twice, one about 6 times (he's in the 15-20psi range) and one only once.

Then again, I can have it welded up for about $30 locally if/when mine does let go.

At that pressure, I'd look at the Cosworth. Supposedly a little better "durability." But, having not owned one, I couldn't offer much insight for you. I'm sure there are plenty of guys in here that can offer personal experiences with it.

 

i have one and no cracks even when i accidentially had the wastegate tuned too high and made a few 15 psi pulls, most of my driving was at 10 psi. where exactly is it cracking? everything on mine is pretty damn beefy i would imagine cracking the throttle body first

 

Mine is sturdy so far. I've hit 10psi a few times according to the log.
The others are cracking at the base of the runners I believe.

My Vortech friend says that his cracked when he gave it "surprise boost." lol
Downshifted into 3rd and punched it immediately. Bypass valve closed, boost jumped to 8psi in a split second.

Just makes me more careful with mine.

 

You'd be better off with the stock plenum and a spacer for either NA or FI applications. Just get the plenum polished if you want some bling. The Kinetix SSV and the newer Velocity version are both crap for anything other than show. They don't make any power and have a bad history of cracking under light to medium boost.

 

+1 stock plenum is fine for making power... spacer optional. I dyno'd exactly the same with or without a spacer.

 

i never found anything on that i just found a bunch of stuff that the newer tapered version showed losses in NA but gains in high rpm FI, i do still intend to do cams just not right now so it could be a benefit. not to mention the stock manifold is a ***** to try and add direct port meth and a aftermarket AIT sensor

 

I lost power NA with the original SSV. I haven't seen any compelling evidence that the newer tapered Velocity version is significantly better. If you want gains in a high RPM FI setup, the billet CJM intake manifold is the best option.

 

Where does it crack? Can you guys post a picture? Is it the welds not holding??

 

FAPFAPFAPFPFAPFAPFAP

everytime that name comes up, I jizz myself, and then I fap. It's just wrong.


If it was half the cost there's no doubt in my mind I'd have one. But for 3k? i'll stay with my 200$ spacer 1/2" spacer.

You wouldn't happen to know the runner design, would you? I'd love to have my buddy recreate one.... (we're just about to drop the motor back in... might just have to get him to fab some stuff with the excess aluminum we have hehehehehe).

Not even 1 hour later I've got an idea together. just need to get to a computer with solidworks!

 

You can see the runner design in these pics.

 

Yep I jizzed a little too.

 

Thank you rude. Seriously. That's awesome.

Damn I'm really going to have to put up a build thread soon... maybe once the cars running.

 

Mother of all that is Holy and pure on this earth.....

That's magnificent.

 

alot harder for the methanol/ait setup im trying to run though, and ALOT more expensive too lol. theres a couple dynos showing gains on fi but i think alot of people have stayed away due to the inferior design of the original.

as for the cjm........yah price lol

 

Charles should bring his other version back with the TB neck in the stock position and have enough units cast to turn a profit at a ~$1000/unit. I think he will sell them all.

The Kinetix "show" welds are a known failure point. My understanding is that they can re-weld with a bead and it'll hold, but it'd be up to you to grind and polish it so it looks decent.

 

which is too bad i cant use it as is.. cuz it looks fantastic. .but yes.. ^^^ Id certainly buy one.

 

yah i dont give a **** i was honestly thinking of matte blacking mine, not a big fan of shiny
