[Andy Greene]

I must be getting old, or its been waaaay to long since I ran my 40 mono-

Base line pipe length needed- CMB45/Cooper QHP - from case center . I wanna say 10 5/8th's ???

Would rather run a tic long than chase a needle for now btw, so I dont wanna hear 9 1/2

OMHO, lose the cooper pipe and run a OPS 67 with a stinger muffler. Let it breath, and remember 0 Dnf's = Wood. RRRay ==={} B)

Interesting, 67 pipe on the 45 motor ? Never really had any issues with the setup Im going back to- but Im open to ideas. Do tell ??? What kinda length are we talking about and why the larger pipe on the smaller motor ? I dont have an OPS pipe but I do have a 13cc macs ?

OPS pipes were never meant to run at nitro numbers we run. The 67 has the vol. for a 45, stinger reduced to approx. .395 set at 10 and 3 daughters. Shoot me you addy, I'll hook you up with stinger muff. NC ==={}

 

[ALLAN YUEN]

I know it must be an up north thing - but for the life of me I cant figure out how far "3 daughters" are , but I will figure it out
