Brake pads

I prefer Hawke Blue's (HB104).  There is no apparent adversity to the
rotors, they last well, they are easy to bed, and the application of
braking pressure corresponds with braking (no sudden lockup).

KEY

this is keith from hawaii with the 1984 red devil.

last solo II i broke the car again.

on the rear axle, the 1/4" steel key that holds the hub for the rear sprocket in place sheered in half.

please help me understand how a steel key sheered in half and an aluminum hub got by with little damage other than being warped?

any suggestions on what type of metal key to use would be appreciated.

i am running a single row sprocket with 530 chain. i was running a 16tooth up front with a 52 tooth rear sprocket that is cut in half to aid in quick replacment. (5 minutes to change both sprockets).

i have heard a 5:1 ratio is best for autox with the kawasaki eng. the smallest front sprocket i have is a 12 tooth. and there is noway i can fit a 60 tooth rear sprocket. ( there is a brace for the rear end that will limit the diameter of the rear sprocket).

thanks for any suggestions.

p.s. yes they did cancel the hawaii super prix.

oh well i guess racing will never make it big here. (except for the hydroplane boat racing.)

brake hoses

Do stainless steel braded brake hoses need to be replaced. I think there may be a restriction. when i bleed my brakes not much comes out of the right front bleeder and a little more out of the left front. and the rear it just shoots out when i am bleeding the brakes. does this sound right?

thanks for any suggestions.

RE: brake hoses

First disconnect the braided hose from the caliper and check the flow to the
caliper and be governed accordingly on the flow observed from the braided
hose...Suspect the problem is in the caliper, either the internal passages
in the caliper on the crossover tube....I'm guessing you are using the
Wilwood Mini-Dynalite Single caliper that has 2 bleed screws, one for each
piston....

Thanks for your input.  I'm going to go with the Hawke blues.

Batterys

I have a KBS Mk V that I'm currently rebuilding. It doesn't have an onboard battery.

I want to run a surge tank setup. This requires an electronic fuel pump I am told. So I guess I need to find a place to mount a battery. I will keep the external battery connector and will have a larger external battery on the car when starting it. However I'd like to be able to start off the onboard battery in case of an on-track stall, etc.

I'm considering the SBS 14 Amp hour battery because of it's small size. Strangely enough it is rated with more CCAs than their 17 Amp hour battery (200 CCA vs 180). So here are my questions...

1) Is this enough for the occasional start (off the onboard battery only)?

2) My external battery should be hooked up in parallel with the onboard battery correct?

3) Should the external battery connector be hooked up "in front" of the on board battery or doesn't it matter? By "in front" I mean between the onboard batter and the starter.

4) Lastly where is a good mounting point for the battery? I considered the right side pod but it seems a little flimsy. I also considered just in front of the jackshaft on the right side. Any suggestions.

Thanks in advance!

Brake system

I'm refreshing as much of my new 85 Red Devil chassis as possible, and right 
now one area that I am focusing on is the brakes. Currently it had 
bagel-sized rotors tucked partway into the wheel, with JFZ calipers, and 
lockheed M/C assemblies. Should I toast the current setup, in favor of a 
larger outboard setup as on pictures of the sidewinder, or are the 6-8 inch 
solid unvented rotors sufficient for a first year thrash-on car? Also, the 
fuel cell is a non-baffled sidepod mounted unit. Is this mounting 
configuration still legal? Thanks again!

RE: Brake system

The solid rotors are the basic standard on all F500's except the
Sidewinder....With you having an 85 Red Devil your primary concern is if the
roll hoops have been updated to the current legality which I believe is
1.375 diameter .095 wall thickness....Unless the roll hoops are up to spec
the car won't pass tech to get on the track. If the car is being used for
Solo then it is OK as built....All Red Devil's came with foam in the fuel
cells be they side or center mounted.

DMD Motorsports

Hi:

Does anyone know if the telephone and fax numbers for DMD Motorsports have changed. I tried to both call and fax them yesterday and never got an answer. I used the numbers posted on the F500 web page under "Suppliers"

RE: Brake system

Jeff,

I bought an 89 Red Devil a few years ago that had a brake system like yours.
Wilwood Dynalite singles should bolt right on to replace the JFZs.  I also
easily replaced the Lockheed MCs with Girling integral reservoir MCs.
Wilwood also makes an MC that looks exactly like the Girling, but I've had
bad luck with those (soft pedal, leaking).  The new Red Devils still come
with side pod mounted fuel cells that have foam inserts, so they are still
legal.  Chuck is correct, if your roll bar is not updated, you have a bigger
problem than the brakes.  Best of luck.  Cory
