They quote a 12-20+ horsepower increase with 14-22 ft.lbs of torque

Worthwhile and will it fit??

Opinions please Jimmy, Gavin or Guy?

Thanks

Not road legal?

I dont' see why it wouldn't be road legal, forcing in more air! Just make sure you change your fueling to compisate it.

That's just in the States due to thier over the top emissions laws.

I heard sometimes manifold swaps can result in more HP but less torque..

Id love to see a dyno sheet for stock car and then a modded car..

Watch the torque curve..

I dont understand how it "forces" more air in ? The boost should remain the same it only changes the amount being stored in the plenum and the way its delivered . Fueling will adjust to suit the new mod anyway , they run motronic ecu's .

Exactly right , you'll find the gains they are quoting are probably for a 1.8t with a gt30 or something where increased plenum size will benefit the engine .
