Default T/B to head lengths?????

Hi, i'm putting a set of bike throttle bodies on my 2L zetec engine. I'm using the injector sandwich plate off the standard zetec inlet manifold.

I need to know the best length for the inlet tubes between the head and the T/B, I'm assuming the shorter it is the more BHP is possible to get but sacrificing torque

Are there any general rules of thumb for this type of set up?

Any help appreciated as I'm getting it welded asap, croft is only round the corner

Bri.

It doesn't matter as its the overall length i.e inc the trumpet length that matters.

What car is it fitted into?

Its fitted in the the rear of a Mk1 fiesta

I always thought the longer the inlet manifold the more torque you could possibly get and the shorter the more BHP you could get.

It wont have any trumpets on the intake, just 4 cone filters.
