Student in Clemson, SC. My Formula Society of Automotive Engineers team is building a formula car to compete in May. We are using a 600 cc 4 cylinder, 4 stroke motorcycle engine. We are designing a fuel-injected intake. I am looking for info. on a fuel pump and injectors for this baby. fuel pump capacity is about 10 gallons/hour = 60-65 lbs./hour injector capacity is 15-18lb/hr If you could give me some numbers, I'd really appreciate it! More about the car project: These cars have lots of rules concerning safety, design, and includes using a 22 mm restrictor plate!! It consists of about 90 schools for U.S. and Brazil competing in Detroit in May. This is our first year racing and we want it to be fun. The cars can pull 1.3 g's on a skidpath, and 0-60 in less than 5 seconds. Tom Buehrle Clemson U.

Other than these resistors, the L-Jets all appear to be basically the same inside. All the resistors of interest (in the several I have looked inside of) are mounted on terminals about 1/4" above the board - it looks like they were intended to be changed for different engine and injector sizes. Any ideas? I need a new box for my '81 BMW 745i (Bosch 0 280 001 124 or 127), and they are extremely rare. On the other hand, 733i boxes are readily available. Thanks. - -Charles cmorris@xxx.com ------------------------------ From: Steve Lamb Date: Tue, 16 Sep 1997 13:37:48 +1000 Subject: Re: o2 sensors in Australia >Steve, did you check out the site I gave you ?? > > > > Partlink@xxx.com Tom, I sent a couple of messages to this address on got zip in reply. Others in the States have advised that a single wire sensor is about $US40 plus shipping. Once you do the conversion plus add shipping it works out at around $A70, which (for me) does not make it a sufficient saving (~$20) to make it worthwhile. Others will have a different view, of course............

An ex-girfriend had an early 80's (82-83?) Ford T-bird with a *carbureted* 3.8 liter V6. It had the trip/mileage stuff on the dash and a fuel flow meter in the fuel line between the carb and the mechanical fuel pump. It's near the front of the motor and it's got a couple wires coming out of it... That's about all I remember. It's been several years ago, and I tried to spend as little time as possible under the hood of that one... Go to the wreckers and look for some 80's carbureted T-birds or Lincolns that have the mileage meter stuff...

I've merely requested some advise, tips, hints, and directions about where and how I should start and conduct my research... I am not asking anyone to do my job for me....I'm completely willing to put in both the time and effort to learn! I was just hoping that I could ask for a few "starting tips" and "pointers". Hey! If asking for "directions", is not "netiquette" with this maillist I apologise.
