I know this new IM gained ~50whp "peak" on a vorteched Z, but how come the N/A results have better average gains across entire the rpm line? I would suspect the FI would have the same gains across the board too, if not better.

*FI Dyno chart for reference*

 

good point...

 

I believe the baseline Vortech Dyno there is w. the Kinetix V4 ... so it's not a direct comparo w. the stock plenum.

 

this seems suspect why is the baseline sooo low?

 

I think his baseline is with 20's also.

 

I can do w.o. the selective filtering of the dyno info and see ALL the dyno runs plotted. The readers can decide for themselves which one's to throw away.

 

they cant find a bone stock z to test this thing out on? I would think people would be jumping for the chance

 

This stock car must have had a reflash because they let off RPM at 7100 which means reflash was done, now was it before or after the manifold install? And what effect does this have on the overall outcome. Somthing isnt adding up?

 

Listen, the baseline is what the baseline is.

This is generally why we dont do our own dynos, but because of the larger amount of testing and changes, we did our own dynos.

I guess all I can say is trust me when I say that theres no "funny" business going on with the baseline.

We did 3 baseline runs , here are the numbers UNSMOOTHED
run 1 - 223.00
run 2 - 225.3
run 3 - 227.2

Smoothing generally takes a couple hp off, below are the manifold runs with no smoothing. Run #2 below is the one on the graph, but also notice the number is higher below because it is not smoothed

run 1 - 234.8
run 2 - 237.6
run 3 - 238.2

 

uh oh the doubts are starting to creep in

 

We had the rev limit increased with a limited reflash. This was done AFTER baseline runs, and before manifold runs.

There were no changes made to timing or A/F

 

I think you guys that are disappointed need to realize what's being compared here. Unless you have a complete solution for the entire manifold, all the upper intake manifold & spacers out there will have near similar results (including Hydrazine's, AAM's Angled, APS's upcoming, Crawford's plenum, the old/new kinetix, etc). Don't get me wrong, the new Kinetix manifold is absolutely gorgeous of all the current solutions out there, but I think people overhyped it. You can only do so much when dealing with only upper manifold.

The same would apply if 350EVO released only their upper intake manifold, you'd also see similar numbers between what's already out there. However, 350EVO is working on an entire solution (replaces the whole OEM manifold). They are probably the only company right now that will produce the desired N/A results people are looking for. Otherwise, don't bash on Kinetix just because their numbers are too close to Brand X's plenum/spacer.

Personally, I would have gone for the new Kinetix (because I'm really into the appearance of how my engine bay looks), Crawford's Plenum, or 350 EVO's upcoming solution, but I won a black powder coated cast Crawford plenum for free from Crawford a few weeks ago at ZAttack in Nashville, TN. Since I wanted one of these 3 upper intake manifolds anyway, I'm going to stick with my Crawford one. I like how it looks in my engine bay and it performs very well. Those of you who haven't done anything to the upper manifold are in a very good position right now. Kinetix, hands down, is the most beautiful and performs just as well (if not better) than the other guys' solutions.

 

Which I believe is true, our own expectations were not that high, people were hoping for LARGE numbers, and I am very happy with the results.

We also think this will continue to perform with better results as more mods are done to it (intake,exhaust,cats, cams,etc.)

 

glad to see someone got the pic out. Took me time to get back to my desk.

Base numbers do not seem off to me. Most stock Zs put down around 235-240rwhp SAE corrected. This car is running 20" rims. That can easily account for the 10hp loss at the wheels.

What I like here is the nice gains across the entire powerband. They're not big, but you also aren't waiting to 4000+rpm to get more power.

Now, as has been mentioned... when is that darn GB starting???

 

definately not knocking but just trying to gauge what this would do to my car which just has intake and exhaust

 

Definitely and I'm glad you guys are satisfied with your numbers. As you said, your numbers will only increase as people do intake/exhaust mods. It's just many of the people anticipating this were expecting like 30hp increases which is impossible with just an upper intake manifold solution.

As I said before, your new product looks ****ing sweet (especially polished). Those of you who haven't gotten into any plenum mods need to get in on this group buy. Of course a lot of people are saying "$700 for an upper intake plenum is crazy". But then you have to consider that most of the solutions range from $200-$400. That leaves about $300-$500 and I know many people who spend more than that just dressing up the engine bay (I know I have).

 

thank you for the dyno, but to make us more eager to buy it how about a run with a modded (light) CAR, LIKE INTAKE AND EXHAUST?

 

The numbers seem low? Maybe I am wrong but why was reflash done and did it net anymore HP?

 

I am with him...or wait is he with me?

Either way I am good lets role that GB....

Jeremy

 

I think you are right Clint. That explains it.
So it is safe to say that the new IM have about the same gains at low/mid range of the rpm line and decent gain at highend comparing to the V4 plenum on a FI...But it may have about the same gains over the entire board comparing to the V4 on a N/A?(looking at the baseline vs new IM dyno).

Does anyone have a baseline vs V4 dyno handy?
