restrictor effects

[aious]

hi,
thanks to grant mahler for the help.
as i have searched the forum but could not get the answer to this question
can someone tell me the lower limit of rpm greater than which the effect of restrictor on air fuel ratio comes on picture. and similarly the upper limit of rpm above which the restrictor effect cannot be controlled by power commander.

can someone give their dyno result of their engine(honda cbr 600 f4i) without restrictor?
as we have no setup for dyno in our college.

and if some teams if have used power commander in past can give their maps so that we can refer to them and see restrictor effects.so that we can compare and can make an approximate idea??

i am adding a map that i had made out of a file (.xls) from forum only? can anyone tell that this map can run with restrictor . because the file is not fully explanatory so it was difficult to understand it.

That is a result of fluid dynamics. This has been discussed on the forum many, many times before. There are several ways to get a basic idea of where the effects will be significant. Logical thinking, asking a fluids prof, asking an I.C.E. prof, or asking a good mechanic you could probably get a reasonable answer.

Here is a thread started recently:

I know that it sounds weird and completely counter intuitive, but with our GSXR600 controlled by a Power Commander we actually had to add fuel almost all the way through out the range. We were also running on 100 octane, so the chance and effects of accidental detonation wouldn't be so detrimental.

Using someone else MAP might be a good start, but every engine, intake, and exhaust will be different. So just because someone has been able to flat line the AFR for their engine, doesn't necessarily mean that it will work for yours.

If you want the MAP we have that worked for our GSXR, you are more than welcome to it, just PM me.

Our restrictor begins to choke power at 10,500 - 11,000
