Hey guys,

I have been looking at threads about the new Kinetix intake and have noticed that most are untuned. The one saying it is a Show Piece had a 20hp incrrease and is very rich. Lorca is rich and also has increases, and untuned. Can everyone post their tuned charts. I want to see what this thing is really capable of. I contacted Kinetix today and they are going to get some dyno charts from tuned systems and post them.

Take care,
AlanL

 

Jeremy's is tuned and rich also. they ran out of tuning room, small hp decrease.

 

Alan, I did the testing on the "prototype". My RWHP and TQ #'s were questioned when they were posted (i.e. "Bad Tune"). Plus, some of the RWHP gains were probably as a result of the IM richen up the A/F between 3700 and 6000 rpms. Even after getting the finished product, long before the GB, the #'s were OK, but some GREAT tuning and 28 pulls later we had the following:

 

Man I wish my air/fuel looked like that!

 

THat looks great SungNamZ
Hey 20003z. If Jeremy's car has been tuned but is not "in tune" then you still don't know. As you can see by the SungZamZ's A/F, his hp went up when it was leaned out to a reasonable amount. It appears he was in the right range of A/F on his, and his hp is up. Looking at the dyno chart from the other post G352NV and Lorca's, they are incredibly rich. G352NV's was trying to blow a hole in the bottom of his dyno chart it was so rich. I am wanting to see other cars that are tuned to proper A/F
ratios.

AlanL:-)

 

I have dynoed 375hp before. This one is 361hp. I have a return fuel system, Walbro Pump, and 440 injectors. When I was using an FMU mine was very hard to tune. Even with the 440 injectors and no return fuel system. Previous tuning took a couple of hours with problems in the A/F. The line you see on the dyno took 4 pulls. More pulls were done because of tip in enrichment.

It can! Your tuner just need to devote the time, be patient and work in 500 rpm cell increments starting at 3500 rpms.

I am sure he has been looking at some of the threads/posts? Did he ever try to communicate with Ryan at Speed Dreams or perhaps Sharif? He needs to work on getting cells below 3500 and 0 psi boost to numbers starting in the 10's and getting perhaps into the 7's.

 

Besides having the TS "Limited Flash", I return my ECU to TS for flashing when I changed the injectors from OEM to PE380's.

 

Let me get rid of all the garbage. This show my A/F after the Kinitex Polished SSV IM was installed before tune and then after many hours and 28 pulls of adjusting.

 

Jeremy, do you have any fuel system upgrades? I have the AAM spec fuel solution for FI. Same as AlanL. I also have the TS ECU flash for FI.

Do you think that this would be beneficial to have in tuning for this manifold?

 

This is probably the best and closest example of a side by side of stock vs. Kenetixs, at roughly the same AF. At the top, some of the gain is a result of slightly leaner AF...you can see that on the chart. But in the midrange, the A/F's are nearly identical, and I see some decent gains.

Thanks for sharing this...looks like a very good tuning job by SD.

 

Looks like the gains maybe in the tuning gurus out there but with this being the best gain(sung), nobody for sure knows the exact hp gains of the SSV.
I have looked at all the people who have posted their numbers in the past week and so far LeMans lost a tad of power, G352NV got 373hp and Lorca only picked up 9hp. This is confusing the heck out of me.....

 

SungNamZ: was the boost identical on the before and after run? And what about the ignition timing? was the fueling the only thing that was "tuned" or were there other variables? how did the coolant temps compare between the runs? how about the intake air temps? I guess my point is, can we say that 100% of this increase in HP was from the manifold or not?

Being a dyno owner myself I can say without doubt that "back to back" pulls are worthless unless all conditions except for the test variable are maintained. I'm not pointing fingers at any person or product, I'm just looking to further understand the testing that was done. Considering the huge gains seen on your car it seems odd that others are experiencing far less of an increase. Obviously tuning matters, but on any manifold that I've built/used that actually increased power, the first step was that the car went lean as a result of ingesting extra air... once the AFR was richened back up to the old ratio, the power increase was obvious. It seems odd to me that others are reporting the opposite phenomena with this manifold and that its installation makes them run richer. The only way that would make sense (other than the manifold being worse than stock) is if a higher MAF reading was scaling the fueling up to a level where it is disproportionately richer. For example, imagine if the ECU's tables were such that 10% extra metered air selected an index where it commanded 15% extra fuel, thus leaving you 5% richer than before even though you have more air coming in.

 

Note that no one should be looking at peak gain on sungnam's dyno chart. The dyno operator stated that he (unintentionally) hit the button to end the run before the 350Z was through the entire powerband. (on the dynojet, this causes a spike of power)

So if you are looking at 55rwhp and thinking that's similar to what you'll get it isn't. Look at the numbers on the rest of the powerband.

Just wanted to remind everyone.

2jz, the higher air flow reading wouldn't be possible would it? The MAF is pre intake manifold and therefore there should not be any increase in avg. MAF (correct me if i'm wrong: it wouldn't even do this on a turbocharger setup because I don't think it would change the airflow enough for the MAF to be out of avg. range.


Like Sharif said in another thread, the only way we will know how much power this intake manifold makes, is by tuning the same A/F ratio and comparing the dyno charts (preferrably on the same dyno on the same day). I also believe dyno-operator-error (intentional or not) should be non-existant on these tests.

I'm hoping that this I.M. will gain at least 15-20rwhp so it is at the bare minimum for power vs. price for those who bought one.

 

butt dyno likes the new IM even though my car is running crazyily
i need a flash BADD i got:
crank pully
injen coldair
kinetix SSV
xerd test pipes
gruppe s ypipe
HKS 3in single

a flash would gain me some good power i think

 

Unless the MAF was maxed out before it will increase it's reading. Think of it this way, if there is no more air per second passing the MAF, then there can NOT be any more air/second making it into the motor... the new intake manifold doesn't "create" air, it just helps whatever is coming in through the MAF and tubing get to the heads with (hopefully) less resistance... if its easier for the motor to suck air through the intake then it will ingest more air total, but of course this extra air has to go past the MAF meter...

and yes, in the case of a blower or turbo, the extra air will be metered by the MAF as well, again, unless it's maxed out...

one situation that could allow the extra air to slip under the radar would be a speed density system... in other words, you might have the same air TEMP and PRESSURE as before, which the computer interprets as the same amount of air, but if in fact you have a better flow path you will be getting more air... THAT is actually the entire reason for the invention and use of the MAF... nothing escapes its view... it is the ideal metering device (in terms of accuracy), it's only downside is the flow restriction that it provides...

I believe that is true, regarding the MAF readings, plus tuners have been telling me about the sensitivity of the factory MAF sensor.

I believe that a true comparison would be dyno factory, install SSV and tune to same A/F curve and redyno for after results.

All these cars are reacting differently in regards to the A/F with the SSV install.

I wish everyone's car would have the same reaction to the SSV install, but there are just far too many variables. Tuning is far less critical in NA form, where we are getting good feedback from our NA users.
