How much tilt, for a Webber IDF ?
I notice DCOE's tolerate, some "tilt", how about IDF's ? Making my inlet manifolds, and want to straighten the runners. Thanks, roverman.

I like "tip-in", of the throttle plates, towards the short turn radus, of the ports. Thanks, roverman.

Re: How much tilt, for a Faux Webber IDF /port injected?
I learned from "Richard" at West Coast Racing Heads, IDFs' are very time consuming, to get correct throughout the range. I want the "look", so why not use 48's as TB's, with port injection ? Perhaps Fred Key, has heard of SDS, injection controllers, in his domain ? Used as TB's, I could tilt the IDF's at any angle= straighter inlet port. Ported 907 head will port/flow to 300 cfm., and stay dry. Coolant passages limit the inlet port sizes. Onward, roverman.

Re: How much tilt, for a Webber IDF ?
The setup of IDF is time consuming while once synchronised you need to find the ideal idle jet, main jet and air corrector configuration, but same can be said about TB's as you need to map the program on a rolling road or during driving.
If you haven't bought the IDF's then you could also use Jenvey's TB : [www.jenvey.co.uk] or TWM/Borla TB's [www.borlainduction.com] When using the IDF's as TB's you could also check Megasquirt and Haltech as software. Cheers Rik |

Re: How much tilt, for a Webber IDF ?
Only IDF's, will look retro enough, for me. "But" as tb's, I can tilt them any angle, to increase the tuned length, think cross-ram. Making my own inlet manifolds, I can have the stacks, cross each other. Onward, roverman.
