thanks matt
hey im in my last year of Mechanical/Biomed Engineering
and can apply the 'theoretical' calculations regarding stress, strains and fatigue
if needed
but dont want to
can i ask what you're doing it based upon
is it good old intuition?
and what kind of engineers did you approach
This part first, yeah pretty much intuition, and overengineering, and trial and error. Luckily and this is no lie I haven't had to cut something off which is highly suprising. I did put one on the spars less than 90 degrees to the back of the subbie but it ended up working in my favour (equally surpising). As for engineers I rang up my version of the RTA in the ACT and they gave me a list of auto engineers that they recognise and I rang each one up telling them what I wanted to attempt and just went for the one who either a) didn't laugh or b) didn't say it had to have everything worked out (ie a plan!).

Matt, have just read what you were saying and have two quick questions.
1. Do you plan this on paper or is this a mould, change, weld, unweld, change, check, modify, weld again, check, change etc etc process...?
2. What do you say to an engineer..? I understand building, so if I want something built I go to an architect who draws it all up and then I talk to a builder who understands from the drawings what brick needs to go on what brick... but what do you take to an engineer..?
(apologies for stupidity... the simple questions come before the hard and more technical ones oh master..)
I think I answered 1 a bit above. I did make a jig that I sat the subframe in which is always a definite don't try this without sticking the subframe i a jig, that my first piece of advice! I then sat the engine in the jig after cutting the front of the subframe away, then measure, judge, have a go, hope for the best, and most times it worked out OK.
As for the engineer it was a strange situation. He came around with his clipboard and I basically showed him the Mini as it was and I had another dry frame sitting there and basically described to him what I was trying to achieve. He nodded alot and rubbed his chin and mumured alot. I told him I was going to use a jig and he seemed reasonably impressed by this. He went away and wrote his initial report (I don't know what happens to this?), then he says give me a yell when it is running? From there we are going down to the old Canberra Dragway and I have to put it through its paces and if the whole thing doesn't fold up like a pretzel I get my certificate then it is off to the Rego people. Most engineers I spoke to are either perfectionists and purists or pesimists (ie it can't be done) just keep going till you find one that shares the dream, but don't go ahead without one as there is a good chance that no matter how good your work you won't find an engineer that will certify a completed project.
Cheers
Matt

yes A COUPE!
I think that the adaptation of the subaru system is amazing and cant wait for the finished results.
