I've used an IPU from ADD Engineering and they are wonderful. Fairly simple system, but the flexibility and control is very useful.
I'm starting a "budget" build on a track car with some friends and we are looking for something similar, but much less expensive. I've noticed that a good number...
Thanks for the link. I have read that before, but it had been a while. It does not seem to specifically address the above questions though. (unless I read it wrong, which is definately possible.) the study seems to hit on various chambered designs, and then hits on a few perf core type, but...
I am searching for information on mufflers and their designs. I've found a good bit of information scattered about, but still have a lot of questions.
Most of the muffler designs I am investigating are "straight through" designs, perforated cores with some sort of packing material around them...
Thanks for the replies. I've used the headerdesign.com website for calculating/verifying the calculations on the target lengths.
My main question was, if space/packing does not permit the full length that is desired, is there a "compromise" length that is suggested. Instead of just doing "all...
when calculating the optimal primary and secondary lengths for an exhaust system, what options are there in terms of altering the lengths. i.e. is half length ok? quarter length? what are the options/effects?
what other things can be changed?
I used a tool to calculate the target primary...
