Alright, I've got a few theoretical tech questions here and I hope to get some answers.

What is the difference between 4-2-1 headers and just 4-1 headers? Which is better/yields greater gains?

Does anyone know the redline for a B18C GSR engine?

Is it better to duct cold air to a boxed-off area of the engine bay (containing the CAI) or to duct a tube directly on to the CAI?

Also, does anyone know where to find mugen parts? I can't seem to find any vendors.

Flames, explanations, expanding my questions, and anything else is welcome.

T.I.A.

4-1 header will provide a specific powerband, whereas 4-2-1 may provide a more broad powerband

Redline for gsr engine is 8000

cold air intakes provide a spike at low-mid rpm at the expense of high rpm power
i would rather duct air to a short ram in an enclosed area in the engine bay

talk to mike m on the board for mugen parts
