Well my rear mount Turbo RX8 GREEN-T survived the nay-sayers and the dyno. Here are a few pics and the dyno run.
Car Specs: kinda fuzzy since it's a "put-together" meaning mostly off the shelf
2004 Nordic Green
Haltech Nexus
Half-Bridge (built by Eddie Renown)
Primaries - Rx8 yellows
Secondaries - Seimens Deka blue shorties 650 both
Comp Turbo oiless mounted in rear
@10psi 273-275hp (motor still not broken -in)
Modified Holly 6port intake w/ Racing Beat adapter

 

totally different intake but the rear mount has been done. hows the lag? cool set up

 

Congratulations on completing and dynoing your setup. Don't think anyone has actually posted dyno results for a rear mount before so this is a first.
Results are about what I would expect to see given the specs provided.
