Hi Guys, As many of you know, I bought an ATI D1SC for my project truck. I know very little about this blower except what I have heard and seen at the track. With the large number of P1SC's out there, I have been asked if I would post a picture of the D1SC impeller so here it is:

Now I would like to see the impeller of the P1SC if someone has a good picture. I hope this helps for those that wanted the info.

 

I'm changing my oil tonite and will snap a shot if no one else beats me 2 it.
( i wish they'd beat me to changing MY oil!)

Thanks 00EXPO, I thought my impeller was the same as the P1SC but I can see a difference. How did the oil change go?

 

I think the impeller is the only real difference, and is why the D puts out 12PSI and not 9.

The oil change went well, I have things really tight on the back side where all the rubber 90's are, and it takes a while to get the clamps and hoses right., Only took about an hour, along with some minor tinkering. As soon as my 12 # pulley comes in I'm going to take it out again and enlarge the fender well.

I relocated the MAF (location of plug) to the top of the tube instead of the bottom. I noticed a slight decrease in throttle response. I will be playing with the location in the next couple days.
