40 IDF-how much hp?
Posted: Fri Sep 05, 2014 12:47 pm
I have a 3 pair of 40 IDF Webbers. I see people have used these on anything from stock 1600 to a 2.7 T4.
I understand the venturis are changeable.
What horsepower will these reasonably support in a occasional street car?
I recently acquired a 912, 914, Thing, a rail, and a Manx, all need engines.
I am hoping to build a strong T4 for the Porsches with the 2.0 heads.
I have a big valve head T1 motor, 1776 I think, older heads make unknown, and some stock 1600 dp.
So I hope to build 2 stout T4 and 3 various T1.
The T4 will be 2056 with stockish 2.0 heads, a better cam don't know which. How bad will the 40's hurt this combination? Should I go bigger?
Does the 40 work well as a single carb on a 1776?
Thank you.
