We decided to take the concept of improving the Throttle Body to the next level.



To reach our goal three areas were given extra attention...

TB Intake: Velocity stack bevel cut improving velocity and airflow.

Butterfly actuator rod: Machined for a lower profile, which allows better
and smoother airflow.

TB Exhaust: Velocity stack bevel cut improving velocity and airflow, and
as such allowing more flow in to the new AGS V.2 or massaged stock SC
runner.


Available sizes:


59mm : For 05 MCS (no cel light).

60mm : No more flat spot.


62mm: All out performance. (flat spot possible depending on software)


58mm for MC: Great uppgrade with great HP potential.

We feel this is the most improved TB on the market bar none.
The TB can purchased directly from us, or from one of excellent dealers
around the country and internationally.

Price: $348.00

And if you have any questions feel free to call us....

Will a core charge be required? I know that dinan does not require one? Will you be keeping up with them? Some people like to keep there origional stuff in case the new equiptement doesn't work up to there liking?

Good work

This is kinda a question I have been woundering, does the mini use a mass air meter?

 

What do you mean by no cel light? Also I will have either the JCW or Randy Webbs software, do you know if either of these has a flatspot with a 62mm??

Thanks

Larger throttle bodies on an '05 supposedly saw check engine lights with the larger throttle bodies. I've never seen it myself, but that's the word. I think M7 could better explain it.

 

I am leaving for San Diego, so I will not be able to answer questions online
but feel free to call me on the celli.

how does increasing the velocity in the region of the butterfly do anything? I can see the improvement to airflow in easing the transitions, but velocity?

 

jlm, I think somewhere I read you’ve peered into the TB while it was on the MINI at full throttle. Did the butterfly ever reach a complete 90 degree opening? From what I’ve seen from tell tale markings on mine is that doesn’t open completely.

 

Pretty darn close:




BTW, it would be pretty simple to attach a Magnehelic differential pressure gauge to spots just upstream and downstream of the throttle. Do a WOT run at a specific RPM, record the pressure drop. Install the replacement TB and do a WOT run at a specific RPM, record the pressure drop. Compare the two.

If the values don't change significantly, then the new TB isn't offering any useable reduction in restriction. If your goal is simply to get a more touchy throttle, then any bigger butterfly should do the trick.

 

Ok, I give I have seen this before and haven't been able to figure it out. What is a WOT run?

 

WOT = Wide Open Throttle

 

If they do, that means the TB does "[offer a] useable reduction in restriction." Cool .

 

Ok makes since now. Thanks.

 

had to be two years ago...that is a pic of my rig on the Helix dyno, sucking hard at WOT, 62mm TB. a scary place to stand while taking the pic, I might add.we found zero increase in hp, switched TB's on the spot to check. no flat spots, though. the 62 is still on my car.

 

I saw both an EML and an SES within 4 miles of driving with a 62mm TB on my 05 MCS. Switched to another 62mm TB and the same thing happened. I went back to stock and there have been no problems since. I am anxiously awaiting my new M7 60mm to give it a go.

 

C'mon guys dont question this item.I'm sure it will out flow anything else on the market by a MARGIN

 

I wouldn't mind seeing some testing numbers. Dyno numbers don't mean that much, but based on certain things, IE WOT isn't always available so how many CFM is able to pass through from 25%~WOT with the tb?


What about stock how big of a variation of the CFM numbers are you able to obtain?

 

i make big bore throttle bodies for the cooper s and i havent seen a check engine light on a single 05 car yet... ive only done 2 or 3 05's... hmm... wonder whats going on... maybe its just luck... maybe its a "hit or miss' problem on 05s...

 

ps the stock throttle body is 58mm! do you really think their is a benefit to have a throttle body that is 1mm larger than stock? Just curious...

 

Well, if there's a benefit to 60/61/62/63, then there's a benefit at 59... If it's not the bottleneck though, it doesn't really matter how large you make it.

 

I am guessing that you've never had a big bore TB on your car. Although it does not make a significant amount more hp it does provide a noticeable improvement in torque. So you'd better have your hands on the steering wheel when you push the go-pedal!

Give one a go, mate, and test it for yourself. Most vendors on NAM would be more than happy to give you a refund or credit toward other mods if you are unhappy. They surely do not want/need the bad publicity. My bet is that you won't be sending it back.

 

Doesn't seem likely since HP is a mathmatical derivation of torque.

 

If you consider 4hp on a 208hp car significant then I guess the TB adds a significant amount. Personally, I do not. My point was that there was a more noticeable torque improvement than a noticeable hp improvement. If someone is going to buy the TB for hp alone then they should spend their money elsewhere.

And thanks for the math lesson...haven't gotten many of those since my chemical engineering courses in college :smile:

 

I'd LIKE to see the difference in 60 vs. 62 mm TB HP and Torque

Especially with Pulley, CAI, larger injectors, Unichip, etc....

Dont forget the throttle response. On the MCS that is the main thing to be had from a TB...and it's a quite important one at that. Who doesn't love quick throttle response

 

Isn't Torque Dirived from HP. Since the toque on a car can vary immensly by simply adding more gearing? If you want more torque add a jackshaft and a gear reduction. More Torquey! But HP is your independent function.
