dyno question ?

[t6shee]

ok am new here,

 

i just bought a 2004 shee in mint condition with stock pipes a week ago.and i just ordered toomey t6 pipes, 2into 1 toomey air filter, vforce3 reeds, cool head with 20cc domes and i am advancing the timing +4 degrees. and razr2 tires. ( i know no performance gains there but its pointless to make more hp if you cant get it to the ground.)

 

 

going to the dyno next week.and was woundering how much hp can be gained from a dyno tune vs a non dynoed shee with all same mods ?

i dont belive ur see a HUGE diffrence in # from a none dyno tuned bike to a dyno tuned bike

I don't believe you will see any difference at all if a competent tuner works on the carbs without a dyno. Remember, a dyno only gives data. It is the tuner's job to know what to do with that data and make use of it.

i understand how a dyno works. all they are doing is useing a wideband o2 sensor to monitor th air fuel ratio. i was just curios thats all. thanks for the replys thou.

We dont do that on either of the dynos we use. We jet for max hp and torque.

i agree with that stament but isnt the wideband o2 there to prevent from running to lean and at the same time gaining max hp & tq ?

Most of the guys I know that have them only use them on 4-strokes. They dont like the thought of the 2 stroke sauce getting in them. Any builder who is good with a dyno, will be able to identify if your running lean just by watching the numbers on the warmup runs. Dave watches stuff like water temp as well on the crank dyno.
