FSAE Guys, Step inside

On my locla CL this popped up.... Giving me REALLY bad ideas on a big boy go kart.

FSAE motor and diff. Anyone have a clue as to what the rear end is? Motor?

Its cheap and close to home.... No ECU, said to be custom single TB, thoughts?

Odds are its the Torsen University Special, or whatever it's called, diff that basically every FSAE program runs in some kind of custom housing.

Well, Buy it of course !

In reply to Furious_E:

Any idea what CV's it uses?

One of the main things you need to understand is that FSAE rules require a near-complete redesign of the car each year, so backwards compatibility is not highly valued. Some teams are worse than others about making one-off parts, but expect many of the components to be things that you will need to have custom machined, and you WILL want to take a hard look at everything to determine whether it's safe- it was most likely designed by somebody who hadn't finished engineering school yet

Based on appearance, I think that's probably a late 90s or early 2000s car, but it could just as easily have been from a school that was behind the curve. The engine looks like a CBR600 of some sort, and that intake will have a 20mm restrictor built in.

Thanks for the input! He says he thought it was a 2005 motor, but has no real details. From the add says 20 ish hours on the dyno, but no race time.

I dont think the safety issue is any worse than if I built it myself! But I do understand they try to make everything as light as possible which mean minimal design sometimes.

The thing that has kept me away from owning any FSAE hardware is the lack of a mill to remake broken parts. It seems easy to whip up another set of brake pads or differential upright when you have access to a fully tooled shop and plenty of raw materials. At home it becomes a daunting task to keep a full car running. This drivetrain is somewhere in between.

Agreed, I have zero experience with it, and no mill or lathe.... But this seems like the least complicated parts.

Link?!? Is it limited slip?

That could be REALLY helpful for my challenge build. Let me know if you decide to pass.

I think I can barely make out a cam sensor on the left front side of the cylinder head in picture #4 - that would make it a CBR600F4i engine.

You'll need either a standalone ECU or a stock ECU and a Power Commander to run that intake since it has the 20mm restrictor required by the rules.

As a current FSAE member, I would strongly advise against this. The diff is $3500/4500 dollars US, and while very reliable get expensive when they go bad. Engine has custom oil pan from the looks of it, the likes of which I have built and they tend to cause oil starvation in a car chassis. Remember, all of this stuff is built by students, so buyer beware, custom parts are expensive.

However, if you have the bravery and fab skills to do it, those headers and diff parts are unobtanium. Replace the intake with stock, mount in car, make it stupid fast.

The add expired.... If it pops back I'll pass it along if I don't pick it up. He was asking $200

I figured mega/microsquirt and a pile of tube would make it easy fun go kart. I need to teach the kid to drive

Booo I came for all the encouragement!! Bit really I appreciate the input from people in the know! I'm still tempted at the price point!

I can get thing machined as needed but can't do it myself.

The FSAE I had was basically built from scratch or a mix of parts stuck together. Mine had a lawn tractor diff. with Beetle axles hooked on to custom hubs with real Mini wheels. I knew the guy that helped build it and even he didn't remember what all it was made from. Had a Judson supercharger on a tiny rotary snowmobile engine that fed a torque converter. Everything had some level of custom work done to it or was flat out created from a block of aluminum. Still, I planned to keep it, I have machine tools, but I was too tall. I don't recognize anything in those pics.

Oh, and to answer your question, I can't see what the diff is, but chances are it's either a Taylor Race Engineering MK1 or MK2, or a Drexler. Really the only diffs that get run in FSAE these days, everyone runs those or custom ones to my knowledge. Motor is 100% CBR600, looks like F4i to me. All in all, for $200 bucks its worth it, just be ready for headaches with diff mounting and replacing the intake and wiring with stock.
