Hi im after a few pointers in fitting a fireblade engine into a "7" style car.

Does anyone have any measurements for height and where abouts a good position is for the sprocket etc, all your input is apperciated.

id say fit it as low and as far to the left as you can get it mate to allow the prop to be as straight as poss..

had some nightmares with mine...

I have just done this (last weekend) to be honest I just put it where it sat nicely.

If you have a flat bottom sump (like the AB performance one I have) I created a false floor to sit it on so I could slide it around in the engine bay and then aligned it how I wanted it. Basically the engine is in-line with the left side chassis rails with the outer most part of the engine about 1" inboard of the top tube. This lines the output flange up nicely and gives plenty of clearance. Once it was were I wanted it I started making a cradle that I taked together with the engine in place.
It doesn't seem to be an exact science and all cars are different and have differing restrictions on engine position.

(Somebody will probably now inform me that this is all wrong though)

If yu look in my archive there are some pics of the engine placed in, I might have a better pic on my phone that I can upload later.

Edit to add the picture, its not great but you can see the piece of plywood clamped under the chassis to sit the sump on and then how I have aligned the top of the head with the chassis rail with some clearance.

If you car is a Locost it will probably be easier than mine as the engine is tiny and the Locost engine bay has a lot less strengthening tubes than mine.

Ah ye, i can put the car on the bnch and have a play around with engine position thanks

Doctor

You got an email address, off tomorrow will take some photos and measurements of the indy, will you be building the sides to locost sizes or the extra inch of the indy.

try to get the output from the engine parallel to the diff face. Having it parallel to the outer chassis rail could give you problems. I learnt the hard way.

some good sites, just do a google for propshaft alignment - e.g. http://www.vibratesoftware.com/html_help/html/Diagnosis/Propshaft/Propshaft_Angles.htm

No shortage of holes in that chassis mate!

There's around 2500 holes mate

There's 10,000 holes in Blackburn Lancashire.
Sorry I thought it was the Friday song thingy
