No idea really, but I wasn't expecting it to be that much! I'm really just building this thing because I can, and I like the characteristics of supercharged engines compared to 16Vs.
I'm used to V8s and TDIs so I'd rather make something with lots of torque low down rather than revving to 7K to get the best from it, but I guess that depends what the power curve looks like when i's running....
Would I be right thinking that if try and get maximum airflow through the engine (head, inlet, exhaust), I can get more flow with less psi? That would help intake temps then wouldn't it? Otherwise I'll have to have a hyuuuge cooler at 18 psi
Maybe the spec should also read p&p head, 4-1 header & 50mm inlet?
