I'd take an inline 4 motorcycle engine any day. Moto GP bikes often have >230HP from 1000cc powerplants.

Time for another update as I sit in the library procrastinating by any means possible. This past week, I finished up TIG'ing our test stainless headers... (pictures to come, thread where I got advice on how to do it -> http://www.diygokarts.com/vb/showthread.php?t=23898) With a whopping half...

Obviously, quality is everything, but a billet one will be da** near perfect, aside from grain imperfections at an atomic level. Let's find a GrabCad model, write some GCode, and CNC them...

Good call! I wasn't thinking of doing all that extra, but it surely gives exactly what you'd be looking for. I want to spin up a fly wheel and see where it bursts... For SCIENCE!

Just came across this in studying for my materials class. I wonder how close of an approximation this can get to when a fly wheel would actually fail? I think the biggest issue would be finding exactly what material the flywheel is to get its yield strength.

Each tube comes with a label corresponding to the line number from the BOM you sent with the job request. We do the model in SolidWorks, then go through and make all of the trims to the tubes in the order we want for sturctural purposes (secondary/tertiary tubes mouthed to primaries). You can...

Alright. We definitely have an older Miller machine, I think it's a Syncrowave 180. And the tubes from them have what I'd say is a normal, oiled stock finish. I'll try to get a picture tomrrow. For prep, I'd lightly hit the surface with some 120 grit or so, then wipe with acetone and go for...

Doc, the event date in Barrie is set for May 22-25 and the page for Formula North has more info, too. It's at the Barrie Molson Centre and is open to the public. FN was much more lax than FSAE Michigan, so I feel you'll be able to wander just about anywhere you wish. I don't think they had...

You use 2% Th for aluminum? I've always been told pure is the go-to for aluminum. Also, we got our chassis tubes made by VR3 Engineering.

Recently, our team held a car show on campus. I just wanted to drop off some photos and show everyone some of the awesome cars that came by. Below is one preview picture and a link to a small album of pictures my friend touched up in photoshop. Album

Thanks for all the info. I figured that we would need to get a lens to do it properly. We do have a flex torch, but getting different nozzles would be nice because we have some crazy angles to weld (see the screenshot). Those flow rates should help too, as I don't think anyone around has...

The plug idea is a pretty good idea for using less gas. Granted they're only 1.375" tubes, IIRC, so fully purging them won't take a ton of gas. I'll have to look more into the fluxes, but I still don't know how easily we'll be able to apply them. I also have to do more research into gas...

Hey all! So, this year for our racecar (check here for all sorts of shenanigans http://www.diygokarts.com/vb/showthread.php?t=15130), we're looking to go to single piece, CNC bent headers for a seamless exhaust, aside from collectors into the muffler. We may end up going down the route of...

We should be there this year. Our plans are for Michigan, Lincoln, and Formula North (Barrie, ON).

CSM? Were you guys at Michigan?

Design of the new car is coming along much quicker this year, and the model is far more complete already, and we're not nearly done. Take a look. This photo is from the the team's FB page. Feel free to like it! ;) Sorry it's not attached, downloading from FB saves as a .png, which isn't an...

Fowler, this one is for you. So, my dad sent me a text the other day asking if I'd like to go see some pretty nice cars that a co-worker of his had... He told me the guy had a brand new Cadillac CTS-V (556HP stock), a race-ready Cobra in all of its American muscle stereotypical glory (don't...

From www.motorcycle-usa.com... Horsepower: 98.06 hp @ 13,600 rpm Torque: 42.35 lbs.-ft. @ 11,300 rpm I'm guessing it's just the bike. I don't know how large the stock intake is, but if we were able to feed it though more than 20mm, we surely would! And the a-arms baffled me the first time I...

Here are some interesting shots from a few days back as well as two rendered shots. We've had it out and running now, but broken a few things... :D Build, test, break, repeat, huh?

On another note... Here's the graphs from our engine this year. It's a CBR600RR, but the intake is limited by a 20mm restrictor. :( https://sphotos-a.xx.fbcdn.net/hphotos-prn1/901672_398099783621918_646088926_o.jpg
