DIY: ZTL2 Front Brake Air Scoop

[34nineteen]

what have you done yourself to keep buell alive?
well let's see now: Have helped hundreds if not thousands of board members diagnose problems....source parts....provided advice and counsel....provided impossible-to-find part numbers.....checked factory inventories for parts availabilities.
Have shipped parts overseas on numerous occasions to board members who could not source them locally...all at dealer cost.
Have given away free new and used parts....clothing....gear....tickets to motorcycle events.....endless goodies.
Sell oem and aftermarket parts at a few percentage points over dealer cost to help out board members on a tight budget. Some of those sales even fell into the category of "pay me when you get the money".
Have sold approx. 15 mint condition low mileage buells to board members at extremely fair prices.
But that's just me.

^^^^^^^^^ yes!!!!!! ^^^^^^^^^^^

I like looks of the scoop, but that's a very subjective comment TPEHAK.

It would take 'quality' (as Mr. Pirsig meant it) empirical, evidence that it not only cools the brake, but that the cooling effect actually increases brake performance at a 'street' level.

1: IMO 99.89% of XB owners will never get a well maintained stock rotor and EBR HH pads hot enough to experience brake fade. Ever.

I come from a time where bolt-on additions to vehicles were pathetic assumptions and untested. Most actually de-creasing performance.

2: You like to post about 'turbulent air around the wheels' so lets see some testing that the airflow to the caliper is actually increased vs. no scoop. It could actually be fun!

 

[TPEHAK]

There is very simple method to test it. Just install IR camera focused on the brake disk and brake with and without the scoop and see the temperature difference.

very nice... ill throw one of these on my HP printer tonight and try it out!

 

[TPEHAK]

Great! Please post results.

 

[marcel]

I will also try it out with PETG. Thank you for sharing the details man! To be honest, I don't think I will need it, but is sure looks COOL! I'll post some pictures here and on the FB page when finished!

 

[TPEHAK]

Cool, I'd like to see your results.

Here is brake air scoop for Buell XBRR

FYI That is the John Player tribute bike built by NCCR, the XBRR had a normal shaped front fender and no scoop.

So that’s cool and all but scoops are made for the ZTL2.. make one for the ZTL brake set up and really impress us..


And the spoke wheels are sexy as hell on these bikes.

 

[TPEHAK]

ZTL2 is such better than ZTL that there is no need to do airscoop for ZTL, just upgrade your caliper to ZTL2 and print this airscoop for your new brake.

 

[Cooter]

No one said brake scoops are never needed on pure race bikes.

I said your brake scoop is good looking, but your brake scoop is untested and very well could block airflow making it worse. No one knows, until its tested to ask:
1) Does it affect the brake temp?
2) Does it cool the brake caliper/ rotor?
3) Is it effective?
4) Is it needed?

Cooter, what's wrong with you, it doesn't have to be tested, it was made on teabag's 3D printer using teafoam !

My brakes are stock and, I don't get any chatter, at least not yet I don't.

1500 bucks for a caliper, I'll leave mine stock for now.

 

[TPEHAK]

I already feel huge difference, now my brake works smoother and no chattering at all on long slopes. So for me this question is answered, this airscoop cools the brake down good enough.

If I’m not mistaken…

The reason for the brake air duct is for cooling of the brake caliper only. The problem they had with the braking system was brake fade from the boiling of the brake fluid. This was due to the mass of the single caliper and the fact that “that mass” could not dissipate the heat fast enough under extreme braking conditions.

If you look at a conventional sport bike rotor designs…

First, they are dual caliper, which gives you more brake fluid to not only absorb heat, but to dissipate it at a faster rate throughout the entire braking system.

Second, because of the dual setup, they are made smaller and thinner which again dissipates heat more quickly.

Third, the rotors themselves are smaller and thinner, which again do I have to go on…

On a street bike, the cooling duct is unnecessary, cool but unnecessary.

Why do you think ‘wickedchop” is always asking for a late model GSXR conversion for his bike.
(There is a man that knows what is truly is effective on the race track.:up

Non the less good work TPEHAK:applause:

It does look cool, much better appearance than the factory parts. In street conditions I haven't noticed a difference with the EBR scoop vs not having it so I'm a bit skeptical when you say you noticed a huge difference. Michigan is pretty flat so Im not super hard on the brakes. Thats just my experience.

A simple test could be to run the caliper temperature strip stickers. They have some that are 250°F-536°F and some that are for lower temp service like 149°-248°.

Some sanding on those parts would make them look real nice, have you considered doing that to smooth them out?

 

[TPEHAK]

I'm OK with layered texture, and it looks like factory plastic parts until you watch on it not very close. If you want to remove printing texture you need to sand it, prime it, sand it again and paint it.

heres the caliper air scoop off my HP printer.

 

[TPEHAK]

Looks awesome! Do not forget to post pictures with installed parts! I love HP printer parts texture, those nylon HP parts should last forever, my PLA parts still work with no issues.

 

[pur pony]

will do. placing and order with mcmaster tomorrow for stuff, ill order up the needed hardware and install it.

Yes, the HP builds great parts. I should have my new HP color printer 1st quarter of next year!..... Id love to build this on my MarkForged X but the supported downface will look horrible.

 

[konarider94]

Those have a much more finished look off of that hp printer. We just got a new stratasys printer at work. Hopefully we get some black asa material soon. Its supposed to have great UV resistance.
