hi guys so I bought stage one turbo busa and I need some help with some problems iam having.
03 busa stock motor
stage one mr turbo kit
old pc3
stock wheelbase
5 up rear sprocket
fuel system
auto meter boost gauge
those are the mods on the bike.
on to my problems.......
bike make 4 to 5 psi in 3rd gear same with 4th 5th gear. I haven't opened up all the way in 5th and 6th. bike gets a little tank slap happy in top gears. 1st gear it makes like 2 psi and 2nd gear it make 3 psi. had the bike dynod and it only made 178 hp at the tire. I have done a boost leak test and the throttle body shaft seals are leaking pretty as soon as the system get pressure built up. that's the only leak I have found.
so my questions are why is it low on power?
why does it not make full boost in 1st and 2 nd gear?
can the boost leak cause it to be low on horsepower?
things I do plan on doing.
upgrade to pcv
a/r gauge
fix boost leak if I can figure out how to do it.
