Salut!

Bienvenue sur le forum Finnbikers Bubuche. Il est bon d'avoir aussi des postes de France.

C'est paquet fabuleux que vous avez dans votre Sportster.
Avez-vous fait des dyno fonctionne avec cette configuration moteur?
Combien de puissance et de couple?

Continuer ä bâtir et l'affectation de nouvelles photos de vos projets.

Here is the english translation  :

Welcome to the Finnbikers forum Bubuche. It is good to have posts also from France.

You have awsome package in your Sportster.
Have you done any dyno runs with this engine configuration?
How much power and torque?

Keep on building and sending new photos of your projects.

Cool stuff! I have no idea what Jarppi just said in French but have you ridden the bike already? How did it work? Those cams sound a bit strange for a supercharged engine, they are normally good for naturally aspirated street bike.

Have you already seen the two Sportster projects on this site, other with Eaton and another with Rotrex supercharger?

Here's links:

Eaton: http://finnbikers.fi/foorumi/index.php?topic=493.0

Rotrex: http://finnbikers.fi/foorumi/index.php?topic=177.0

Hope you don't mind but I'm going to link your pics to www.quadcambastards.com

i put this and i test the last week

i have two problem i think

my andrew came have a 60° overlap (recomended for supercharged max 20°)

and my statique compressio ratio is 10:1 i calculate my dynamique compressio ratio and it s 8.7:1

i look e very nice post whith rotrex and eaton supercharger

a+ eric

Cool stuff! Je n'ai aucune idée de ce que Jarppi vient de le dire en français: D mais avez-vous déjä monté la moto? How did it work? Ces cames sembler un peu étrange pour un moteur suralimenté, ils sont normalement bon pour vélos ä aspiration naturelle de la rue.

Avez-vous déjä vu les deux projets Sportster sur ce site, d'autres avec Eaton et une autre avec compresseur Rotrex?

Yep, you have a problem. That setup is pretty good for a street engine without supercharger, maybe a bit low on compression but mighty good anyway. I know very little about supercharging but I'd say that you need milder cams and lower compression, actually stock cams might work lot better than those N8's.
