Hell yeah they have potential! 240 hp = 168 kW, which is not bad at all, but not that impressive either IMO. They can go better. From memory the EL produces 165 or 175 at the fly, so allowing for power loss from the auto he's picked up maybe 30 or 40 kW? He can get more yet
Course I don't remember the power figures that well so I could be making a dickhead of myself, but I think I'm right.
Have a look around, there are some blokes on here getting pretty bloody good power outputs. Personally, I've only done EF intake, exhaust, and manual to mine and I have little trouble flogging auto v8s....
Total cost of $500 - mind you I wreck my own cars so the box cost me $30 hehe, otherwise it would have been about $1500.
