apex seal
 

I would like to know what does it change to performance and to the engine to change the apex seals.

Thanks

somebody knows ??

it shouldent change the proformance what so ever.
but upgradeing to larger apex seals will allow you to run higher boost.

you say that larger apex increases boost, but with thinner you get more fuel-air mixture. Can somebody light me about that...

Larger apex seals do not make you run more boost necessarily but ALLOW you to run more boost... i.e. stronger and capable of withstanding higher amounts of boost.

I've been told by a few people that the 3mm seal motors won't last as long... the inner rotor housings must be properly clearanced, and that's not easy to get 100% right. I would only go w/3mm seals if you're planning on running over 20# boost. Otherwise, check out the seals I'm running; there's a website out there which gives alot of good info. I can't remember the address; hopefully someone out there can supply it...
