We can do it tomorrow if everyone wants...

I will gladly open up shop on Saturday... we can BBQ some churassco and drink some Miller Light... still have about 10 in the fridge...

and of corse some music will be playing..

 

im good, I got the tester ready.

Do you have the compresor with you?

 

and the final pic DONE

 

Any reason why you didn't match the shape perfectly? I think I saw one posted before that had the exact shape as the rotary works throttle body.

i dont see how you could

 

Hmm. It was a long time ago since I saw the pictures so I think I slightly warped them in my head. Here are the threads I had thought of. Perhaps it is the light but it looks like the runners on the top might have less restrictions. Perhaps they were ported more or just the light/camera angle.

The difference between mines and the one you are showing me is that mines is completely open there no divider i remove it and made all open.... The ones on the thread you are showing me they didn't they are just ported

 

Any more leaking issues?

 

Good question.

The more I look into the RW TB the more I want to pass on getting one.

 

There's really no point in it. The same amount of money spent on something else will get you something much more useful.

 

took my Rotary Work throttle body apart, and the only thing that stops the air from leaking out is a small oring that's in the shaft, and there is a double sealed radial bearing, but those seals are to keep the bearing itself sealed.

bearing and retaining clip


Throttle cable side bearing and retaining clip


TPS side bearing removed for pic.



i have being searching online and found a seal with the same dimension as the bearing, the problem is that once you install the bearing there isn't any room to install the seal.

 

Last sunday at Import Faceoff in Dallas I was talking to some of the rotary racecar guys from Kansas about these throttle bodies. He is running 40 psi with no leaks and Poncho's RX2 is running 50 lbs of boost with no leaks. Possible bad batch?

 

have they done a pressure test, i though i had no leaks until i tested it, small leak nothing big, most TB leaks anyways.

 

All TBs leak to some degree. If those TBs can hold that much pressure I'd consider that a success. How long have they been running the TBs for?

 

I am really on the fence with this. I was going to port & polish my OEM unit during my 500whp build. I really like the idea of this setup, but don't want to sacrifice quality for convenience. The mixed reviews makes it tough.....

 

Ok I'm handing off the torch to someone else now.

This guy seems to be the guy

 

My understanding is that they been running them for about a year and a half, not sure if they pressured tested them or not. I'm kinda on the fench myself.

 

After a bit of research, I plan to just port and polish the OEM TB. My car is a street car, and I think the OEM TB will work best in that application.

 

^smart man. There is nothing wrong with the OEM TB, I don't see any real reason to 'upgrade' it.

 

Send it to me XLR8. I'll do it for you.

XLR8, read reviews before you send your stuff anywhere.

 

Bumping this back up. I got mine apart, and I am going to try something with rubber washers. Once I'm done I will take some pics.

On a side note when I installed this unit I had maade many upgrades (35r to aspec 500r) so it was impossible to quantify any difference. Now. That I have the throttle body off the car I put my stocker back in. I can not feel any difference in top end but my butt dyno feels a difference in response. The stock unit feels slower.

Take it for what that's worth - almost nothing because its a feeling not a number like a dyno.

 

The tps side I added a rubber washer, and a aluminum washer so the tps arm can still swivel smoothly.



On the throttle cable side I added two rubber washers that will press in to the TB. These are basically acting the same as the O rings. If air some how managed to still sneak past I then added a nylon washer that presses up against the TB with again a metal washer that things will pivot against.


I know it is better for a few reasons. The spool seems quicker than the stock unit again - but dyno.
The car will start to lose traction, and chirp the tires through second gear. Something it wasn't doing before.
The car sounds quieter while in boost. I don't hear as much air like I did before.

I still have doubts that it is leaking because the stock unit was even quieter. I will try to do another leak test to confirm for sure but it deffinately is better.

 

Wow man good stuff!

 

So I had a chance to do a boost leak test, and I am impressed. I found many leaks in the couplers, and even my BOV. My throttle body has a very small leak now. I only found it with soap and water compared to the loud hissing it previously made. Right now it is leaking on both sides of the tb (against the greddy elbow and uim). While the leak is minor I will be taking it back off to see if some gasket sealer will close it up 100%.

Despite 45 - 50 degree intake temps fixing all the other leaks has again has made a noticeable improvement in wheel spin, so I am happy with that

I tested the system up 20psi as that's eventually where I want to get retuned to. Regardless of what TB you have it is worth checking for leaks!
