Front tubes

I have struck a problem. Due to the size of my engine, tubes T and S (in original book) dont quite fit. They will fit if i make them 3/4 of the length but that may be defeating the point of them. Any suggestions?





How long can i resist the temptation to drop a V8 in?

This should make more sense. The tubes (green) will only fit if i move them to where the blue ones are. Does this matter?

Tubes

Looking at the book the tube length looks to be quite critical.

How much were you looking to be shorten them by ?
I have just noticed by about 25%. A tad too much I think.

They look like they provide critical triagulation for the upper wishbone assemblys, tr1 & tr2, fu1 &fu2.

I am sure you will get some more advice on this.

can't you do a curved piece instead, you've not left every much, a bit drastic

Ok.
Green line = original design
Blue line = obviously wont work
Pink line = Another idea (waiting for abuse
Black line = Where engine comes to (approx)

Edit - Liking you idea Mr W

bent tubes are bad. bent square section where one wall is buckled in seems even worse.

if i were to need the extra space, i'd go for something like below. it'd be harder to weld, but i'd imagine you could get into it all if you were a bit creative with mig shrouds

Just thinking that the +4 is a tad wider where it matters most with the standard chassis width at the point shown being 506mm for standard chassis and 608mm for the +4 chassis

Would the extra 102mm help in resolving the initail problem in the first instance with clearance

Can someone tell me if the Haynes chassis is 506 or 608 at the front end on the top

so are you building a +4 locost or a +4 haynes roadster?

a haynes roadster is 2" wider than a locost, so a +4 roadster's a +6 locost

did you follow that? you can have a merit if you did.

thats 150mm longer and 150mm wider!!!

That would make the chassis at the front (if the haynes chassis is 608mm wide at the front) 760mm (app) which is nigh on 30 inches wide!!!

And that is between J1 & J2 810mm or 32 inches if you include J1&2 overall
