Pumpers really pump?

[shadow88]

I was wondering how much air do pumpers pump? We know they're directional and I believe they're made to draw air out of the wheel well area. At say 60mph, is there significant airflow to really make a difference?

Probably not effective as actual brake ducting, or we'd see wheels like this much more. Any functional benefit would be negated by the fact that they are narrow and heavy.

I always wondered why they only made the 16" wheels directional and not the 15".

Are you road racing then? Please say yes! There's only like 3 of us here on TM.com and 3000 drag racers

I have 4 wheel disc, independent rear suspension, but I also have close to 4000 lbs, so I'm not a road racer. I'm one of 3000 I suppose. I was wondering if the pumper wheels could assist in extracting hot air from the rear engine compartment at freeway speeds without adding an additional electric draw to my one alternator system.

ah, no

[shadow88]

ah, no

I'm not expecting miracle wheels here that can empty a 10 by 10 room of all it's air in a minute, just assistance.

So how much air do they move? If you spin them on a hoist or jack stands at 60mph, is there a breeze?

I'm sure a wheel like this doesn't come into being without some testing behind it to justify the manufacturing process as well as additional weight.

I road race the GLH.

[Dr. Johny Dodge]

it's only ment to inhance brake cooling - maybe

all oem alloy wheels are heavy as they are forged , not cast

[jonnymopar]

Still my favorite wheels. I've got 15's on the Neon and 16's on the Daytona.

I always wondered why they only made the 16" wheels directional and not the 15".

If I had to guess, I'd say the added cost of having different left and right wheels could be justified on a low-volume premium performance model like the Daytona Shelby (which I believe was the only car to see the 16" version). Where as a Shadow ES turbo was still a car on a budget, so all 4 wheels were made the same. Purely speculation though.

If they are indeed functional, I'd bet that ol' Carroll had something to do with the directional version.

I road race the GLH.

We're taking over! Spiro, Mike W. You, Me. 3 L bodies and a Consulier. Wonder if I should count Benji F, he ice races

I would love to road race my GLH. The only place it raced to was the garage.

[Dr. Johny Dodge]

I can't remember now who made the pumper wheels but they were avaliable from the aftermarket with the manufacturer's name on em

I saw a set on a mazda sedan once long long ago

[Reaper1]

Don't forget me! I road race...well...I will...again...someday...I hope. LOL

You have a running TM Chris?? What is it

[iTurbo]

I just bought a set of 16" pumpers to use on my Spiirt R/T. I plan to send them off to be powder coated white (any takers?)

Anyway, like Mike said (contraption22) I doubt they do much to extract heated air compared to the brake cooling ducts on my CSRT.

I would totally be into road racing, but here I am out in the middle of nowheresville!

Actually...I have TWO RUNNING TM's! 1 '89 SOHC TII Masi and 1 '89 DOHC Masi!

[shadow88]

So nobody has had a pair of these on a car and on jack stands and noticed if there was even a breeze?

I was thinking of modding the lip on the back side to improve the fan effect

and yes i have seen the differece in brake temps on my Glh at misson raceway ( short hard braking course) over say stock pizzas
