So I have short intakes and 44IDF's with 38mm vents
How long of an intake should I go to with these carbs or should I go to 40 IDF's with 32 vents or 28 vents. I have some longer runner intakes and the other carbs so it's just a matter of experimenting I guess. 2.0L Bus piston Web 86B portmatch intake and exhaust ports. 13lb flywheel Bursch SSI Car weighs 1965 lbs 205/50-15 Kumho V700 R tires. Thought of playing with spacers under the carbs to get more length and maybe spacer under the common length velocity stack. Looking for more torque down lower to pull harder exiting the apex of tight AX turns. Whose got the experience of really been there done that? great gains or don't bother. |

Jake, I don't know where this "conventional wisdom" is that you reference is coming from. However, what I said, and Andy said, and a couple of others here have said, and virtually every academic book on intake tuning will tell you, exactly matches what you say above. And it works on ALL engines, not just the Type IV.
I know you don't like "theory", but I think sometimes that if you sat down with a good book on the theory and actually read it, you'd find a lot of the hard-won knowledge you've picked up over the years right there on the page. And a lot of this research is pretty old. Much of it was known as early as 1920, and I doubt there's been a whole lot of new knowledge added to the pile on intake and exhaust tuning since 1950. |
