if you have to ask this question then, imo, gilmours are not really for you

I believe gilmer belts have less drag meaning less friction -equals more horse power .dont no bout rotors but look part on my 8

Synchronous or timing belts don't use friction to transmit power, unlike a v-belt drive. They also can transmit more power with less tension, therefore less bearing load, and they are at least 5% more energy efficient than a v-belt drive. It's a wankel, not like it can afford to lose any power anyway!

Bellky-- Please explain to me how a toothed beltrequires as much tension or more than a V belt or multi groove flat belt. Yes I do understand the issue a wider pulley causes on a bearing only supported on one end. -Sok I'm not saying you are wrong I just don't understand your logic

a lot of guys want them noisy as poss so tighten them up = wear on alt bearings and wreckage of gilmour alt pulley too if not steel.
and in case anyone missed it: the point of gilmours is the NOISE and the LOOKS - to get loud noise they need to be tight, and so result is WEAR on alt bearings (and alt pulley too if not steel)

you know this really depends ay.
rotarys with a viscous fan, and an old hard aftermarket v belt that doesn't fit the v in the pulley properly will need a bit of tension to stop them slipping at high revs - probly more than a loose gilmour running electric fans. (loose gilmours do jump teeth though)
on an engine without viscous fan, a nice new v belt from mazda doesn't need to be as tight as a noisy gilmour, and won't put any where near the load on alt bearings

also gilmours don't slip a high revs like v belts do

I was always told by guys who seemed to know a rotas,that they used gilmer style belts to stop the slipping at high rpm.Some of the guys built rotary curcuit and rally race cars.But most road going cars have them for looks and sound,-rotary,6,or v8.Each to there own I guess.I have always found them troublesome.

The load on the bearings also depends on how wide the belt is as if the centreline of the belt moves away from the bearing the load increases. So the load may in fact increase.
the belt is a GILMER BELT not gilmour . I suppose if you cannot spell the word then using the belt properly will be hard as well.

this means nothing imo
(opinion formed by what you have have posted here - you obviously don't know very much and your credibilty is very low with me)

still an xpert then, definition sorted

on the subject of spelling, it's 'expert' thanks

The load would only exceed that of a v-belt due to the tool who over tensions it to create noise. As a pure power transmission function, the width of belt and tension required would be lower with a synchronous belt.

drill holes in the pullys will make more noise too.

this might be true but is an impracticle argument because almost no-onebuys a gilmour because it's thinner than a v belt
