Hi Harry

How much would you expext the gear box to sustain with this upgrade?

Lars

Hi Lars, gearbox has its limits but over 300 BHP should be no problem at all. Certainly with Quaife ATB diff and offcourse control of left foot.

 

cheers,

Hi guys, these are not my "reversed " ring and pinion sets!!!!! Beware.

 

Mine are fully tested, with nothing but good feedback.

 

 

Mr John D is trying to sell un-tested and wrong ratio cwp sets without any feedback at all through my topic.

 

I rest my case.

 

cheers,

"quote " Harry Martens is pretty much the go-to guy for Citroen gearbox parts for Esprits and any other marque that uses Citroen gearboxes. He has developed a CWP specifically for Esprit use that matches the teeth with the way the Esprit uses the gearbox. I know of at least half a dozen people who have installed Harry's new parts and to date, they are all working well. Harry can also provide everything else for the gearboxes for one stop shopping, and will rebuild your gearbox if you ship it to him.

New, all ready the 4th, batch of 12 reversed cwp sets for Lotus Esprit coming in the next few weeks. Well proven and without any weakness. Be wise. All parts in stock, full rebuild possible.

cheers,

Here is some back ground information about the materials, design and quality HML ring and pinion sets.

HML uses 18CrNiMo7-6 for those sets, which is the standard for hardened sets.

The type of tooth is. Gleason, compared to Klingelnberg, has the disadvantage that Gleason has a smaller tooth foot radius and therefore succumbs faster to tooth fracture.


In addition, the geometry over the tooth length at Gleason is a "circular arc".
At Klingelnberg this is an "Epicycloid", which makes the Klingelnberg system less susceptible to installation errors and house deformation under load.
If you are going to calculate with equivalent sets: Klingelnberg vs Gleason, Klingelnberg will be the strongest choice according to the calculation modules.


About the transmission ratio.

The cars with a 7-31 ratio will accelerate faster and you will lose your top speed.
At the same speed, the car will also go higher in revs, which is less comfortable.

cheers,

Harry
