Well my d1 got destroyed a week ago so i've been talking to Lonnie and decided to go with a D1R.
Has anyone switched like me from a d1 to a d1r? IF so what kinda of gains have you guys seen with them?
Also if somone has any kind of numbers i would like to see them.
I'll be doing a front mount at the same time cuz i dont think the twins will be up to the task of 20+ psi

 

HI

I have a similar setup to you

What did you do for crankcase ventalation?

I have a FAST and am having troubles with driveability issues.

 

It's not a direct replacement, the brackets will need to be modified and you will have to space the blower out about 1/2"

 

i know that i have to space out the whole bracket, but the bracket it self from what i understand bolts up to the blower it self no problem.

 

Crankcase evacuation kit from Mr. Gasket. JEggs sells it, its like 30 bucks, 2 breathers go into both vlalve covers they also supply you with 2 fittings to weld into each collector, you have to buy heater hose though to connect but its only couple of bucks from any hardware store

 

I have a D1-R on mine. It came with the brackets so I don't know if they are the same as the other models but they are different for my old P600B brackets. As far as gains, I'm still working out the bugs but the difference is night and day.
