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. |

Well I knew all that. But what I want is the recipe for the engine I have. I am going to try the 40 IDF long intake with 46mm opening at the top vs 50mm short intakes.
I may make up some spacer shims to lengthen the intake even more. Also try to lengthen the velocity stack. can't go to much as I have short filters. I'll let you know how it goes. By the way this motor does rock above 4500 RPM doesn't fall on it's nose ever I have seen 7200 RPM in 3rd. Co- driver thought I was going to scatter it all over the track. That was 10,000 miles ago. I put a rev limiting rotor in it now. Shift light @ 5500 makes my shift About 6000. |
