Help! We need an engine

[Motu]

we will get there, if we have to beg or borrow we will get there, we are fairly good at getting out of tight spaces.

If you had an engine you could fix yourselves it would be much better - now you are at the mercy of fate.Burt and John didn't panic when their engines blew,they made new parts on the spot.Thought you were Kiwi's?

[Colapop]

You're a hard man awright Motu. But as you say where there's a will there's a way.

I think though that if you're building performance machinery it'd be best to start with top notch kit if you can. If at the end of the day you're forced to rebuild an engine then so be it. No harm in asking for help first up though eh?

What discipline are you studying?

Any discipline can enter into FSAE if they are commited as the project has structual, chemical , electrical etc stuff in it. I know a few in different branches working on things from data logging to carbon fibre stuff.

Burt's bike blew up all the time (which was fine, since he had plenty of time to spare it would seem), and John could shit money (a handy trick), neither things that the university guys have... as the OP has pointed out, and if you'd get your head out of your arse you'd see that.

Why not put two overbored nsr250 (2 * 300 = 600) on a common crankscase. 4 cyclinder two stroke, should easily make 120+ hp and be reliable as.You can get overbore kits for the nsr

[Motu]

If you haven't got the resourses then you don't go for a rare and expensive motor that you can't repair inhouse.First rule - don't paint yourself into a corner.Guess I'm too practical to be an engineer.....

What discipline are you studying?

most of the team are studing Mechanical engineering, with a few electrical, a few mechatronics and few business students. the team size is about 25 people with about 8 people doing most of the stuff.

I'm a natural genius. I have google. What else does one need?

google rocks! there is so much stuff you can figure out with google... i wish i could take it into my exam....

Awww Ixion, was that for me?

How about two Honda RS250 engines? 180hp would be achievable. Can't overbore an NSR barrel, as it's plated. You can use an NSR150 cylinder though, with a bit of modification. Or just fit a TYGA kit.

to compete against the aussies and the rest of the world, you have to have good gear that will perform. we did our homework and that was the best engine for what we wanted to do. if you want to research why we chose this engine the Formula SAE rules are on line at www.FSAE.com. if you want to actualy see what we have done so you know all of the details then come and have a look at our workshop, we are rebuilding the car at the moment.

What we have done with our design, including the engine has got teams from all over the world asking us how we did it. innovation and leading in your area is definitly a kiwi thing (the britten bike?). this is just a little set back that the team will get though, i was just seeing if someone out there might be able to help us with it.

we are working on a v twin design at the moment using two single cylinder yamaha dirt bike engines just exactly like you are talking about. the only reason that we don't run a 2 stroke is we are limited to 4 stroke. no rotaries either. the new design will be lighter, smaller, easier to package and almost as powerful.

Mr peanut, whats a TYGA kit?, excuse my ignorance.

Clumsy sentence. It was the TYGA kit I was thinking of.

Not really for you, just that the NSR should go quite well as a four. Too hard with the RGV, V4s are tricky.

Well, thats a bloody silly rule then., Whats the point of having a contest to design a powerful engine and ruling out the powerful ones!.

Why not have a rule banning overhead cams, and pushrods , too. See who can have the fastest side valve.

yeah, there are some gay rules, but alot of the rules are very open ended to get alot of different designs in the cars. some are space frames, some are monoques, some people make cars that are under 200KG and run a 450cc single, some make turbo inline fours, some have wings some don't.
the rules are done by americans so if you think the 2 stroke rule is bad you should see some of the safety rules...

to compete against the aussies and the rest of the world,

Compete against yourself - that's the best benchmark you'll ever have.You chose a motor difficult to repair,now you are finding out what a smart move that was.Will it break down on the eve of the race,and you'll get to watch from the pits? KISS - frame it.

R6 engines aren't exactly exotic...
