le non equal full inox en général pénalise les bas régimes mais offre un beau gain en haut tout de même. Après et pour l'avoir monté sur ma caisse je conseille celui de grimmspeed dont bluewrx vous a mis le lien plus haut, pas cher et il allie les avantages de celui d'origine (spool) avec le gain en haut d'un inox, le tout pour un prix contenu Après l'équal fait gagner encore un peu plus, mais on perd le bruit sub (les meilleurs equal à "pas cher" nécessitent le changement du carter d'huile sur les 2L )

Thus far, I have never seen an MD321T fail to make 450BHP on a 2.5 litre. A "2 litre version", the MD321H, also exists which sacrifices some top end power for spool; on an 2 litre AVCS car it achieved full boost at 3050 RPM and went on to make around 400BHP (limited by injector flow, airflow was still rising). On a non-AVCS car it achieved full boost at 3300 RPM on the road and recorded 407BHP on the dyno, this time "limited" by unknown engine internals.... Again this is on road fuel without any additives. All quoted figures measured on Dyno Dynamics rollers. For the benefit of others who have not experienced them, I'll try to relate the way they drive to things people are more likely to have encountered... The MD321H "feels" like a VF34, just with more power and torque but the same throttle response. Similarly, the MD321T on a 2.5 litre with AVCS "feels" like a TD04L on a 2 litre (full boost at 2700 RPM), it's virtually lagless. Without AVCS it "feels" closer to a TD05H on a 2 litre, taking a little longer to wind up (full boost around 3200RPM). No data is presently available for MD321T on 2 litre, but one would expect it to achieve full boost around 3700RPM without AVCS.

bon je vais essayer d'être un peu plus constructif. Perso j'ai le M Voilà les réponses que m'avait fourni Mark Aigin à l'époque: Réponse de Mark Aigin de Lateral Performance: "My quoted power figures are at the flywheel, and on Dyno Dynamics chassis dynos. I would consider that the figures we get in the UK, are conservative, compared to figures achieved in the USA, on the same spec' cars. From the info you have given me so far, it looks like you have standard engine internals, and I would suggest the MD321H. This is a 400bhp rated turbo (at circa 1.4 bar/20psi), and consistently makes 400-425bhp depending on engine, and mapping. It gives excellent throttle response, and spool up, and people comment it's very similar to a VF34, until it gets to 3000-3300rpm, where it just takes off. If you're intending to up rate the engine internals, and aim for circa 450bhp, then the MD321T would be the better option. This consistently makes circa 450bhp, and as high as 504bhp/486ftlbs on 109 RON race fuel. The 321T spools up the same, if not quicker than a 20G, and the 321H is similar to a VF34."
