ive never heard of takeda... are these guys new?

looking at wat you get, wont it make more sense just to get the JWT pop charger for cheap with heatshield and net about the same? let me know wat's great about this particular takeda
intake over the others..? was it done by some chinese guy and slapped on a japanese name?

Takeda itself has been around for a good amount of time. The parent company Afe power has been around since 1999. I think the issue with these are the engine heat this car creates, and with no heat shields around the filters you are just pumping hot air into the car.

Can Takeda fix the design for a SRI and provide solid gains? Maybe, but it might be best for them to scrape the SRI and rebuild a CAI system.

oh ok AFE... :)

i see, thanks for the info. yes, i agree that heatshields are needed if you want some gains from SRI. CAI is good, but not sure if i want my Z to sound like a urinal flushing...

werd... even their bmw application has heatshields...

here's the email i got from TAKEDA as to why they dyno with the hood open and also explaining their dyno process using a MUSTANG DYNO:

The Mustang Dyno actually adds electrical resistance to simulate wind resistance as the vehicles speed increases. We have to input weight and HP@50 mph for each vehicle.

As far as testing with the hood open, we are not trying to simulate wind. We need to keep the motor cool so that it does not overheat. If we had to test actual wind, we would need a wind tunnel. That wind tunnel would have to be able to simulate wind as you built up speed and actually blow as fast as your vehicles speed and then some, depending on the direction of the wind. We hear time and time again "Why do they test with the hood open?" I hope this answers the question. We could never simulate 70mph winds you would get on a highway with the fans we are using. For those that feel very strongly about the hood open, I ask them about the vehicle manufactures dyno numbers. They are giving a horsepower reading with the motor outside of any vehicle in a test lab with fans. That is crank HP, not wheel horsepower. We are giving horsepower results to the actual wheels.

What I can tell you is that we test one way for almost all vehicles. We do our best to keep all variables the same except for the product we are testing. If we test stock with the hood open, we are going to test our part with the hood open as well. We key in temperature, humidity, and barometric pressure. The dyno does the correction factor at the end of the runs.

We have done baseline tests on the 370Z. We have sent the driver away with the intake so that the vehicle computer could adjust to the new intake. After a few hundred miles, we will bring the vehicle back in, input temps, and test the same way we did the stock runs.

:tup:

We are dropping off our 370Z this morning so they can do the dyno results. They will be doing a video of the dyno session, results and process.

Idk how but one of our memebers said he saw a -2hp on the dyno.
lol...

very nice...

so they didnt mention anything about heatshields huh?

Thats exactly why they are doing more testing to figure out why. As of now, they stand behind the numbers they got and they are using our Z to see if there is or how much of a difference from the first 370z test car they used.

^ Hopefully they fix that issue, cause I nearly bought them when you had them on sale, but am VERY glad I didn't after I saw the results.

theDreamer 09-17-2009 09:36 AM

Well the email is correct in why they do what they do, but at the same time I tested both times hood closed so it should not have been a factor. Both times the engine was hot from the hood closed and should technically be a null factor in a comparison run. Also, I got basically the same HP to the wheels as others have done on the same dyno with my hood closed when they had their hood open so I am not 100% sure the hood open v. close is a factor.

But anyways, I am still here for the results and hoping for good things on what they can or cannot do.

rednek01 09-17-2009 02:04 PM

in for results and fuzzy numbers :stirthepot:

kenchan 09-17-2009 02:22 PM

i suppose the worst case if they can at least net zero but with good sound, that's still better than just keeping the stock intake.

i'd like to see comparison of takeda vs JWT's intake without the heatshield.

very much so. I am very critical about companies advertised gains there are so many tricks they use or fudge the numbers a bit. and sadly if the gains are less than 5-10 the there is really no way of telling with all the variables involved. Somebody needs to make a dyno in a climate controlled room to kill at least some of the variables that skew the numbers

rednek01 09-17-2009 03:24 PM

Really not trying to hijack the thread but....

In the end dyno's must have been created by a woman, and are like women, results may vary depending on the time of the month, weather, or mood. Why couldn't they be more like a man. Boring and consistent, then that would be no fun.

So if you want to judge real results look at timeslips
