Rocket pipes vs. CPI inframes

[locogato11283]

ill tell you guys would would be a really good test is to take a dune ported 350 and a identical 4mill  with average dune port timing of  198ex and a 130 transfer with the usual add ons goodies,like vforce 2's ,k&n intake  ,33 or 35 pwk carbs ,20cc domes,then get yourself a set of rockets ,cpi ,and shearer inframes and make several runs on a modern winpep dynojet  with low humidity and same dyno setup entirely. i and a million others would  like to see those results

but rockets were designed for 200 over 134! why f with the designers intentions? in fact how many rocket riders have these porting specs? i do!

i think if you asked enough banshee builders youd find those are fairly close to an average dune port alot of people would run with shearers cpi or rockets,and while the 200 and 134 specs are said to be the ideal for rocket pipes ,it also should be mentioned the rocket pipes were designed around the perameters of 7millimeter ported stroker engine too,which of coarse would allow for your bike to run higher durations due to the increased torque and powerband width , 200 and 134 specs seems to me to be a very high port timing for a 350 with rockets ,for anybody that wants any lowend or torque anyways.
