First Visit To Track This Year
Finaaly made it to the track this year and wasn't happy with the results.
First off i spent a bunch of time installing a boost controller and never turned it on last night
because i already had enough with just spring pressure alone.
Sunny day to begin with temps about 75 low humidity, racing didnt start till 330 because they had a junior dragsters before that.
Had trouble launching the bike at first, i bogged it then got back into it and the front wanted to come up, bad 60ft around 2.00 and went through the traps at 175mph.
After a couple more passes i started to get my weight more forward and 60's went to 1.60,but still only 890 at 170mph, but then the tire started to spin about 20 feet out as the evening went on and the track cooled way down.
I went back to a 17 tooth sprocket and this might have something to do with my 60's being a little high,on motor my 60's used to be 145 to 150.
Motor seems to have the power now i have to learn how to use it all over again.
I made 5 passes all were over 170 mph, highest 2 being 175.

Damn 175 is trucking. How much power are you putting down and how much to you weigh???

I have no idea what the motor is making since the last time i had it on a dyno it had a boost leak.
I have the small spring in it now 5psi because i installed a ams-500 boost controller,which i never powered up yesterday.
Running e85 with 4 degrees timing pulled after 5 psi.
I weigh 170 so about 185 with gear.
I imagine the 5 psi spring creeps to about 7 or so before opening,cant even think about looking down at the gauge .

Well like i said i have no idea what the actual boost was,only going by the rated spring pressure which is 5, its a turbonetics waste gate and i heard they usually creep up a few psi before opening. It would be nice to have a data logger for all that,but its only a stage 1 kit and dont want to stick any more money into it.
I suppose i could hook up a airline with a regulator and check when the wastegate is opening to be safe.
