which intake will be giving me more power ... ams vsr or hks kansai .
money will not be the issue cause they r gona cost me about the same price as im goin to a country for vecations where the hks dealers r ,so i can get the hks kansai by hand and save the shipong charges ,and if i get the ams vsr ill have to pay alota shiping charges and customs duty so they both will cost me the same price .
now u guyz plz help me which way shud i go as i need the maximum power .
thanx

dsmdeliveryboy

Probably the vsr, ive heard alot of good things about it and not so much about hks. Hks is way too overated, had the hks tbe on my 05 evo 8 and it was junk i hated it.

I'ver heard a lot of good info from the people running the AMS VSR, I've got a buddy that runs one on his 500+ AWHP Evo and he loves it. I guess it's just a matter of preference but if Money was no object I would get the Indy/ Buschur V2. I hope this helps and good luck with the build!

Don't let the "Stock Appearing Indy V2" fool you. It's designed for PERFORMANCE and it's already proven it's results on Buschur's Dyno. It makes more whp than anything he's tested. Check it out before going to a fabricated manifold, you'll be glad you did.

The HKS with large throttle body was never tested by Buschur. I think if it was it would have made more power than anything else he tested. That is just a guess though.

I have the HKS and I bought a q45 throttle body off Ebay for like $100 and then gasket from Nissan, and 3.5" to 2.5" from Samco.

To this date, the power that Buschur made when testing the manifolds remains at least the current 'FACTS'. Unless another test is made using different parts and combinations, it would only be an 'OPINION'. David, as well as other vendors, get attacked all the time for giving opinions instead of facts. If another manifold/tb combination makes more power, let's see the tests.

same here...have the HKS kansai and a Q45 throttle body.
Haven't dyno'd yet but I think it'll make some good power.

crcain

Yes I agree. I went back and looked at the testing Dave posted here:

http://buschurforums.com/forum/showthread.php?t=20866

The HKS blew doors off the DI manifold, both in low, mid and top end.

The Indy V2 with 65mm TB barely beat out the DI with 3" TB, and where it did better was the early to mid range.

Since you can't bolt a 3" or for that matter 3.5" (q45) to the Indy, but you can the HKS, I think it is a somewhat logical conclusion to believe the HKS with larger throttle body would have continued to beat up on the DI with larger throttle body, and therefore beaten the V2.

Now 9sec9 is right, the fact is, the HKS was never tested with 3" TB so it is just guessing. It's impossible to guess the gains the HKS would yield going from stock, to 3", to 3.5".

On top all of this, the HKS is significantly different manifold and will require some futzing to install. While the V2 would just bolt right on.

Try the Hypertune intake manifold...@ 7800 rpm it makes 45 hp over stock...this was tested against the ams, magnus, driven, Hks, and Buschur intakes in dsport magazine in may of 08. The evo they used for testing had a best time of 9.65 @ 151.41mph. The stock manifold is pretty efficient up untill 5500rpm so non of these manifolds actually increased power until the 5600 rpm range. Hope that helps.

Please click on the link provided above by crcain. You can then judge for yourself, my findings in the intake manifold testing.

Keep in mind a few things. Magnus now makes a new intake manifold that was NOT tested during those tests. I know you didn't ask about his but I want to make sure you know that the model I tested is no longer made.

Also keep in mind that those tests were done, uncorrected for weather in February. The most current tests using Indy's V2 are in much hotter and less ideal weather conditions than the testing done in February.

It is also a fact that the HKS Kansai intake did well and was never tested with a throttle body bigger than 65 mm on it. With the Q45 throttle body I am fairly certain the HP would go up, how much I don't know.

Right now I have the Indy V2 intake on my car with our 65 mm throttle body. I will be keeping that intake on my personal car which has now run a best of 9.42 at 155 in full street trim. I hope to beat those times next time I go out as the overall power curve is the best of all the intakes I have tested so far with the V2.

Also, if you are looking for a fabricated sheetmetal intake, before you spend well over $2,000 for the Kansai and a throttle body, I'd highly recommend looking at the Driven Innovations intake with a 3" throttle body. That is what I had on my car until I switched to the V2 and what my car ran 9.42 on.

Good luck in your choice.

crcain,

As you know when Dave put Hypertune TB on my manifold it beat all of the manifolds that were put to the test! HKS never blew doors of my manifold. It did perform better than my manifold with the 65mm tb but not with 3in! Hence why Dave was running my manifold after the testing.

This brings it down to the best of the best intake manifold test where Dave and Indy designed their own manifold (stock appearance). The V2 performed flawlessly down low where DI performed a bit better in the upper midrange and performed almost the same up top.

DI intake manifolds are now also bolt on affair and no modifications to your upper intercooler pipe is necessary. We also have an EGR option for those who want it.

Cracin your somewhat logical conclusion is worthless, we have dyno sheets to prove it!

DI makes the best Sheet Metal Intakes Manifolds on the market today PERIOD!

HKS manidfold is $2000 as DI is only $950!

David B,

do you still have the HKS unit on your drag car i.e the black car?

Here are the 'interpolated' figures on the HKS vs the recently posted Indy V2. Although the weather is warmer now and conditions change, the V2 did very, very well in the comparison: (Hope they're accurate, I had several interruptions)
ADDED: The Indy V2 was with clutch slipping also.

Come on guys... I'm simply making observations here from what was not totally complete testing. The HKS performed MUCH better than the DI with same throttle body. That is the only FAIR comparison. You can't say yours performed the best when changed when the HKS did not get a shot. It's only logical to conclude the HKS woudl benefit equally from the larger throttle body.

DI... you have an awesome manifold at a great price and to hear it is a bolt-on deal that is very cool too. But the HKS outperformed your manifold! By a good chunk too!

Dave Buschur thanks for doing all this testing for us to work with. It's pretty cool stuff. Such a variety now for the end user to choose from with good test data to back up their choices so they are not flying blind.
