Engine Movement
rayroni - 6/8/04 at 07:01 AM

How much space have people got between the top of their (side-flow) carbs and the bonnet?
In other words, how much is my crossflow likely to move on its mounts?

Cheers,
Andy

depends on the mounts you have used, but i would allow 20mm either way as an extreme on mine. There will be very little up down movement, mine seems to just rock left and right.

can't tell you how far it moves, but moves a fair bit while cranking, then settles down when engine is running

my V6 moved a bit more than I wanted, so I got a tie bar made up - bit like the ones minis used to use (except this one is about 400mm long - mini is short). One end is on the chassis, other to a braket on top of bell housing. Its rubber bushed, so no loss of vibration insulation. The engine is VERY steady now.

Older BL / Rover cars (summat like allegro) with the A series had longer tie bars that might be useable.

I'm using Landrover mounts and have less that 10mm total movement

I think the prob on mine was the angle of the mounts.

The granada ones are donut type. like the LR, with a stud each side. On the ford, they seemd to b emounted at a tiny angle, inwards, towards the engine. I think this kinda make the engine settle into a shallow 'v' for stability.

(too techie for ya? )

I mounted em flat.

wobbled a fair bit.

not with the stabiliser tho!

I made my motor mounts like end of the "a" arms the mount comes down to a welded cross tube with two bushes at each end(rubber suspension bushes from a full size crownvic axle) and a bold goes through them to u bracket welded to the chassis. On cranking I dont see more than a 1/4 inch of movement at most.

Dale,
I`m sure i`ve seen something like that, but i can no longer go back to the page. (Saved as a favorite on different `pooter)
Do you have any pics?
Thanks in advance

Hope this helps. The U bracket on the bottom is just temperary untill as a much tighter fit will be required but it does the job for right now. Rescued attachment mounts_resize.jpg

Dale,
Great....
Thats what I was looking for.
I`ll make to suit 5.0 Ford V8.
Thanks a lot

nomaly the engines rock left-right when not in gear but when you are actually accelerating the engine moves forwards and backwards. I noticed this when the car was on the dyno with the hood off, shoving 160hp through the live axle. no noticable sideways movenment as seen only lengthways

I thought about trying an anti-roll bar drop-link as an engine stabiliser if mine turns out to be a bit 'wobbly'. Some cars have nice long drop-links, not too hard to find in the scrappy.
