Dyno numbers for HKS Hi-Power Ti???
 

I've been patient and I've searched..... cannot for the life of me find dynos for HKS Hi-Power Ti exhausts. I know AK installed this exhaust and only saw +1 HP from it, but the dyno was messed up.

Does anyone know what this thing is putting down to the wheels? I figured HKS would have put more time into marketing their product with dyno numbers.... or perhaps they didn't like the outcome? I don't know. But this is one sexy exhaust and sounds amazing too, but I need numbers! lol

Who has them?

Mine just came in yesterday...I plan on dynoing, but it will be with the G3 intakes and Berk HFCs installed as well. If the dyno wasn't an hour away, I'd definitely do independent dynos.

Sounds good because I'm going with Berk HFC's as well and I've already got the Stillen G3. Hopefully this setup doesn't throw a CEL.

Here is HKS with kinetix HFC on dyno. It makes 305

YouTube - z34 getting tuned

That looks like ilive2win's car. I don't believe he had a baseline dyno so it's impossible to say what gains he got after installing the exhaust unfortunately.

True but the final numbers are good :tup:.

Agreed :)

I don't have the chart laid over the stock at the moment but on mine (NISMO model) the HKS made a small gain all the way through over the factory NISMO exhaust (which already has the better section 1). Peak was 305.1 HP & 249.8 TQ at the wheels on a rainy day and on a Dynojet. Average was about 5 HP higher than the NISMO exhaust. Sound DB level was below 95 DB (for all states that comply with CA law on that). 98's dyno may be more apples to apples for you though.

Sounds very nice but not annoying in any way due to the sub silencers and looks aswesome. Tips are adjustable in lenght as well so it's nice for guys who are running the diffusers and rear skirts.

Hi i'm new here so i don't know what to say but i got a 370z 40th anniversary. I wanted to hook up the HKS Hi-Power Ti exhausts but i don't know the number's it puts out. Does anyone know how much hp and torque it puts out?

That is the whole point of this thread. It's the exact same answer I'm looking for. Stay tuned and I'm sure somebody will get those numbers in here eventually.

According to Import Parts Pro, the Nismo exhaust adds 5.4HP and you're saying you got approx 5HP more than stock Nismo, then it might be safe to say this is a 10-15HP exhaust??? I was hoping it would be more in the 15-20HP but I can live with 10-15HP increase.

It's a little difficult to gauge as the Nismo S-tune exhaust is different than the Nismo exhaust that comes with the Nismo edition 370Z. S-Tune uses a Y-pipe configuration whereas the Nismo edition OEM exhaust uses an H-pipe.

10-15hp is typically the normal gains expected for a catback though.

I just changed my exhaust from an F.I. with 12" resonators to the HKS and I noticed significant low and mid-range improvement with the butt dyno over the F.I.

does any one think magna-flow exhaust would be better then hks hi-power?

um...lol:icon18:

:facepalm:

I don't think Magnaflow looks like this!

Magnaflow will be cheaper but HKS is well built using best materials and equipment(s).

Ha fail!

All this HKS talk is making me excited! My package is coming this afternoon!

Not in my lifetime.

I'll give you the lol on the butt dyno :icon23:, but...

Thier stuff is 100% made in Japan. I've seen it with my own eyes when I did a factory tour in 2001 when I went to Tokyo Auto Salon. That just appeals to some people. The exhaust systems are an impressive combo of automation and hand build. They're the oldest tuner of the major Japanese brands and the most stable. They also have the best reputation for stelling stuff that works and doesn't break. It's not far fetched to think it works as well or maybe even better than and FI. It also has a different look and tucks under the car better.

I'll have my review done soon. I know a fair amount about the company and the exhaust so I'll try to make it an interesting read. Only bummer is I dont have a comparo dyon, just the final result. I'll come back and link it here when it's up.

AK that is looking hot with your carbon diffuser... :drool:

I just got back from Sound Performance, and my dyno results are.....

Baseline was 282WHP and I had the baseline done a month ago, I installed Berk Test Pipes and HKS Hi-Power Exhaust went to the shop today and made............


+22whp it ended up making 304whp I will post dyno sheet later tonight :)



DAN

^That's a good number. Did you get it tuned?

No I didnt get a tune that is just bolt-on gains :)

awesome! im installing my hks today!

You will not be disapointed :)



DAN

That's awesome! Does Berk test pipes make that much of a difference? Anyhow dyno without test pipes?

You will probably get more hp after the tune.

if its not a problem, culd u post a real quick sound clip? I cant find any HKS or ARK exhaust clips.

Here is my sound clip.

thank you :tup: sounds great!!

Thanks you beat me to it putting up a video, I will be making a Journal later tonight and it will have photos and videos of the car and my parts :)

Just so you have a database on my progress


DAN

Tons of HKS videos on Youtube. I have like 6 vidoes up. Here's 1

And here is mine on the dyno...

Very nice sir. Thanks for posting. Sounds great.

What numbers did you get from this exhaust?

I only dynoed pre/post tune. I never did independent dynos for each mod. I did 337whp/265wtq.

Awesome. I've got a woody because you went the same route I had planned on going anyways as far as intake, exhaust, and HFC. Probably won't be doing the manifold unless money flys out of my *** and I can get a TT setup.

Did you say TT setup?:happydance:

Don't forget the extra 20rwhp gained by placing the HKS logo ON the exhaust system.....

True statement!:tup:

How loud is this exhaust below 3000 RPM compared to stock or a nismo exhaust?

Not bad at all after warm up, sounds a little louder/deeper than stock with my test pipes.
