Fuel Tranfer

feeds@yuku.com (Derek Harling) — Mon, 19 Oct 2009 21:01:45 GMT

I may need to add extra fuel capacity for my enduro races. If I had better access I could incorporate a one way valve and let gravity do the rest but right now it looks like an electrical transfer pump from the extra cell to the main cell is the best way to go. This would not need to run full time though - so two questions -

1 - what happens if a fuel pump empties the extra cell and continues running on 'air'? Good or bad? I assume bad.

2 - is there a way of...

Steering Wheel Switch

feeds@yuku.com (Derek Harling) — Mon, 19 Oct 2009 20:50:10 GMT

Against my better judgement I think I'm going to have to use a steering wheel mounted on/off switch. Never having down this before my question is - do I have to use a coiled cord to connect it to the main harness on the car - or could I just use a plain 2-wire cord wrapped around the steering column with some slack and maybe some thin bungee cord to hold it out of harm's way.

Thx in advance - Derek

Gear shiffting

feeds@yuku.com (Sam) — Mon, 19 Oct 2009 11:30:04 GMT

Hello, I've seen a couple of onboard videos where the driver does not take the hand of the steering wheel to shift the gear.
As I am building up a bike engined race car for the moment i would be very interested in this method of shifting gears.

I tried to realise this already on my previous project. ( A 750ccm GPZ powered go kart) but unfortunately I wasn't lucky, I didn't find any actuator strong enough to pull the gear lever.
But as it seams like , a couple...

Selfbuild chain drive differential

feeds@yuku.com (Sam) — Sun, 11 Oct 2009 12:00:10 GMT

Hey guys , i was asking myself if any of you are driving self build chain drive differentials and how you did that.
I searched the forum and found a lot about quaife etc. but nothing about self made parts done with stock parts from a front drive car.
My idea was to take the differential out of a stock VW rabbit gearbox and put a sprocket on that.
For the beginning i will drive slalom races where an open differential is more efficient than a closed one.
Later for circuit...

More Tech Info

Howdy,

Just a quickie note to let you all know that I've been building an online technical library and got another 2 years worth of Chassis Newsletters posted today at www.auto-ware.com/techref/lib_index.htm It is getting to be quite a good collection of racing materials, so check it out.

Enjoy

Car eating chains - causes?

feeds@yuku.com (Jake Latham) — Tue, 15 Sep 2009 21:17:43 GMT

Hi All -

The last two race weekends, I've had curious chain failures on the car.

The first weekend, the chain lasted until the end of the Saturday race. In retrospect, I could hear it going slack around 10 laps in. When I pulled the body off, all the o-rings were gone, the thing was black and blue from heat, etc. Rear sprocket destroyed.

Before that failure, i'd been having trouble keeping it tensioned, it always seemed to loosen up. Not sure if...

CAD Softwares and Space frame chassis

Hi everyone,

first of all I want to thank you those who will take the time to answer me.

I would to design a space frame chassis with the help of a Computer-aided design (CAD) and I would like to know which one is the most appropriate among
Autodesk inventor professional 2009, Pro/ENGINEER, SolidWorks et Catia.

If someone know another one who matches most than these for this task, let me know.

If someone own as well file(s) of a similar...

Two Batteries - Wiring Query

feeds@yuku.com (Derek Harling) — Wed, 29 Jul 2009 22:09:11 GMT

Has anyone ever done this - added a second on-board battery - just for added oomph when the starter button is pressed? I know it adds 'unnecessary' deadweight but that's a different discussion.

In terms of wiring I'm thinking of just adding a separate starter solenoid into the second battery hot lead. In other words with the starter button not pressed the second battery is isolated and doing nothing. When the starter button is pressed the batteries would be connected...

Seat Safety

feeds@yuku.com (Derek Harling) — Mon, 13 Jul 2009 17:11:08 GMT

This has been discussed several times in the past but it is too important not to keep reminding ourselves of the basics. On a different thread a driver wrote, after a severe but injury-free accident, " I also encourage drivers to consider impact absorbing seats like my Bead Seat, I know I would have been damaged in my old hard fiberglass unit in the previous car."

The point that made me raise this topic again is his reference to his "old hard fiberglass" seat....

High Plains Raceway Gearing

feeds@yuku.com (TMoore) — Sun, 28 Jun 2009 10:00:35 GMT

Just a question to all the DSR racers that have run at High Plains Raceway. Edge Engineering will be running a Formula B at the Double National next weekend. Curious what gearing you use. It would allow us to be close on gearing for a track we haven't seen.

Thanks!

GPZ900 ignition problem

feeds@yuku.com (csp54) — Fri, 19 Jun 2009 11:21:32 GMT

so this forum rocks so far guys have been very helpful, my gpz seems to only have fire on 2 cylinders, do I have a pickup problem, or a cdi, swaped coils and the second coil pack works but no spark on 2 and 3. I'm totally new to this engine

does anybody have a schematic for the CDI box? its discreat components so it looks repairable, im a electronics tech so it should not be a problem to repair, just not sure what wires do what
even a pin out of the 10 pin connector would help

Tow vehicle question

feeds@yuku.com (DSR Jerry) — Mon, 01 Jun 2009 12:43:51 GMT

I have the opportunity to get a very good deal on some diesel fuel. The only hesitation I have is that it was to be used in a diesel generator rather than a vehicle. The guy beleives that it's no different than street diesel except it may contain "more preservatives".

Other than the potential tax ramifications, is there any reason not to use this in my turbo diesel pick up truck?

Chain / Gear question

feeds@yuku.com (MCalvert) — Mon, 11 May 2009 05:13:34 GMT

Sorry about this, but I know I saw this question on here, just can't find it. But, suggestions on chain / gears to use would be appreciated. Have a stock '06 gsxr, I am at the point of putting the LSD in the car, but don't have a gear. Engine is 15t, I am thinking a 46t rear. (Think I read that was a good starting point). LSD is a quaiffe. Plan to run 21/22 inch rear tire. Chain size? 520? 525? 530? My thought is a 530, wider gear, more surface, longer life. I am setting...
