MG MGA - waterless coolant

I see MGOC sells Forlife coolant at £15.95 for 5 litres. This is about 1 quarter of the price of Evans Classic Cool as sold by Moss for instance. Apart from the debate about whether one needs this sort of stuff at all does anyone have a comment on the two offerings?

If you really want to depress the cooling capacity that much, just install 100% glycol antifreeze, and it will have almost exactly the same function. You only need to look a the specific heat number, and the boiling point. Specific heat (heat carrying capacity) is way down no any of them.

There is a thread from Peter Burgess on this subject in the MGB board:

On a previous thread discussing waterless coolant I was rather scathing about it's properties. We had a race engine eat its rear two pistons twice and the only reason we could see was a change from water to waterless coolant. The engine has now finished a race at long last with no signs of overheating at all.

I attach a picture of the best power curves we could achieve with and without waterless coolant. There is no difference at all in engine specs or ancillary specs, all down to running on water or waterless coolant in the engine/rad. With the waterless coolant we had to retard the ignition to stop pinking hence the lack of power at lower rpms. We even had to drop the cr on the rear cylinders with shims under the plugs. The top end lack of power mainly comes down to the viscosity of the waterless coolant plus poor igniton. It takes more bhp to drive the coolant with the water pump as it is thicker than water. John who runs the car was spot on when he said...I reckon the waterless gloop costs bhp to pump it!

The uplift at the end of the power curves happens if I lift off power just before I press the stop record button and it fools the software as the pau momentarily has no inertia as there is a cush drive twixt rollers and pau with a fraction of 'soft' clearance.

This has cost me two engine builds in terms of labour as my warranty is free labour with customer paying for parts if a race engine dies prematurely.

Peter Burgess has been given this link to another forum. It appears to be a technical appraisal of Evans waterless coolant. http://www.pistonheads.com/gassing/topic.asp?h=0&f=12&t=1269629&nmt=
