Hi Neil,
I'm also trying to weigh the diffent systems against each other and found the information given on SDB's website the most convincing.
The biggest gains will surely be achieved with modification on the induction side, complemented with a sports exhaust and a more free-flowing cat + ECU reprogramming. These modifications will already take you near the 200 BHP territory. Mild cams may free another 10 - 15 BHP.
My favorite kit is SBD's 214HP taper throttle kit with cams.
However, Jochen (numog) suggested the Cosworth system desinged for FWD applications. This system features only one (bigger) throttle body but long induction pipes for more torque.
He got me thinking with his advice because I now fear that I'll loose to much torque in the lower revs.
On the other hand he'll have to route the air intake around the rear end of the engine because the induction side of the FWD system faces towards the bulkhead. He'll probably modify the hood "TOK-style" to create a "ram-air-system".
I'd also appreciate comments on this matter.
