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. |

Please correct me if i'm wrong anyone.....
Generally speaking most torque engines use a low rise intake. More low end and quicker response. The closer to the head the better the response. At low RPM's the air velocity is slower unless the intake runners are more narrow. If I was you i'd go more narrow tubes. Shorter intake. The trade off. Smaller intake runners = less top end. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Top end motors use high rise intakes and velocity stacks to optimize air pulses stacking one on top of another. My intake is a high rise and runners are very open all the way to the ported heads. I am trying to avoid lots of low end torque in my setup. The oposite of what you want.
