Intake manifolds testing - April 3

[DCJ98GST]

Looks like RMDSM.org is doing testing for Intake manifolds:

RMDSM.ORG presents the 2004 Intake Manifold Shootout on April 3rd, 2004

FRH
BJ'S
Magnus Motorsports
Extreme Motorsports
Venom
STR
Mitsubishi 2g intake, extrude hone
Mitsubishi 1g intake, extrude hone
Stock 2g intake
Stock 1g intake

The test

Mount each intake on the same test vehicle
Run the test vehicle on an all wheel drive dynamometer (Dynojet 248/224)
Record the following
RPM
Air flow (in grams per rev)
Air fuel ratio
Torque (uncorrected)
Horse power (uncorrected)
Time index

The test vehicle (courtesy of Dave Landry)

1990 Eagle Talon Tsi AWD
2.0L 4g63 (8:1) motor using 30 psi of boost
Stock head casting
HKS 272 intake/exhaust cams
Stock throttle body
2.5" intercooler piping
3.5" GM MAF (blow thru)
MAFT (zeroed out)
Buschur Racing front mount intercooler
Forced Performance 3065 turbocharger
No intake on the turbo
No exhaust beyond the 3" tubular o2 housing
DSMLink V2

The results (installed pic, video of pull, dyno charts, dsmlink dat and csv)

Should be interesting.

I will definately keep an eye on that. Thanks for the heads-up.

FINALLY, too bad I already ordered my smim.

 

[Dick Hertz]

This should be good Hal rocking 30 psi on a 3065

i lub hal.

 

[Mike 99GSX]

Great job for going through all the trouble I'd like to see the Buschur SMIM included in the testing though

 

[DCJ98GST]

Anyone taking bets on which will give the most hp?

I am going w/ BJ's or FRH

magnus..........woot woot

April 5th is my bday, looks like I'll finally be buying myself an intake manifold.

I've been waiting forever for a good shootout like this.

 

[Slappster]

Hell ya this is gonna be great

 

[DSMJim]

Wow, this is going to be amazing, I can't wait to see that.

Just a note about this test.

We are not running around asking for intakes to test.

The intakes being tested are those that we have been asked to test.

Manifolds have been submitted by individual owners as well as vendors.

If Buschur Racing wishes to submit a manifold or if the owner of a Bushur Racing manifold wishes to submit his/her manifold for testing, we will gladly add it to the list.

The fact that a specific manifold does not appear on the list should not be taken as a negative.

In addition, there is more to manifold performance than how much torque/hp a manifold makes.

Where in the powerband does it start to "make" power, and how long does the power band last.

Different manifolds will have different curves, but at the same time those different curves may suit individual setups better.

Daily drivers, auto-x, and drag racers will all have different power band needs.

Matching the manifold to the performance goals of the car will ensure you get the best performance for your investment.

Finally, quite a few people are involved in this test. Everyone listed on the webpage deserves a thank you from the DSM community for helping to make this test happen.

When is this testing going to be completed? This should be very interesting.

 

[L2RTSiAWD]

Many people will awaiting the results from this test. It will help alot of people be able to choose an IM for there needs.

 

[DSMTurbos]

sweet, that rocks, thanks a lot for organizing this!

 

[Tallen]

Thanks Hal!

 

[Violater101]

This is very good news! Can't wait to see the outcome.

 

[Groomz]

I would like to see Dejon Tool's SMIM for the 1G tested.

[Kingdom]

wow, this is gonna be great!! thanks to all the people named on the site.

I think the two main competitors are the SMIM and the FRH!! which will make more power without losing bottom end?

good thing I didnt buy one yet.


and dont forget to do a pressure test after each manifold install

Check on the site, its there.

What are your precautions for making sure all the dyno runs are under the same conditions? For example, your first manfold might be on a crisp morning run at 9 am, but the last one may end up being done at 2 pm when the sun is blazing at full strength.

Is the car going to be cooled or warmed up before each dyno run?

Are the runs going to be open hooded? Fanned?

How many runs each? Are you going to try to finish all the manifolds in one day?

What you're doing is really awesome, and definately not an easy task. I just wanted to ask because i'm curious and would like to see the data accurately displayed (even if it means saying that manifold #1 was run at 60 deg but Manifold #5 was run at 80 deg) so that we can make accurate comparisons.

I'm sure you know what you're doin though and i'm probably just blabbering off on things you already know.

Sorry.

I see it now. Thanks.

the people doing it dont post on here so dont bother asking questions.
