I just ordered a Procharger kit for my 04' Z and the local shop has me down for the P1SC system. I just started reading up on these systems here and on the corvetteforum and they also have a D1SC blower unit. Can someone please explain the actual differences between these two blower units so I can better understand what it is I am getting. What can someone expect putting each of these units on an otherwise stock car. Maybe I should have the installer get me the D1SC instead?? I really don't know... FYI, I did call ATI and ask this question and was more confused when I hung up the phone than before I called.
Tony, I can't stay on line very long right now but tell us what else you're doing to the car and what rwhp level you're trying to obtain and we can give you some better answers
So far the supercharger was the only mod planned. I was hoping to be around 500 rwhp from just the procharger. Maybe I'll need to consider doing some other things to get there... Right now the car seems a little on the slow side. It's only got 1000mi. on it. Had it to the track last week and turned 2 runs of 13.4. My driving was off but the car seemd like it was really doggin it. My former 99 coupe was doing 12.8's with just exhaust, airbox and a computer tune. I'm hoping to get low 12's maybe high 11's at some point.
The P-1SC will work great on a stock motor and if you have some mild mods. The D-1SC is recommended if you have more extensive modifications (long tubes, heads, cam or a larger displacement motor). This is also a good choice if your at a high altitude.
Antivenom and myself just installed a P series on a stock block car weekend last that the customer bought from Tom.
This is the best way for you to go with 10.5:1 compression that the LS6 has.
If you plan on lowering your CR and doing heads and cam then the D like I have or as Mike has the new F series.

If it were me; I would buy the D series and a smaller boost level pulley, This way when or if you should grow you won't outgrow the charger. Pricing is similar. The D series will produce lower levels of boost while producing less heat than the P series unit.

Don't disagree with your statement, Greg but if this is all he's going to do, I'm not sure the additional cost of the D1 is justified, do you?
It sure seems more expensive to me to outgrow the P series just to buy a D series. But, the last one that I did, the guy told me that the price difference was very small. Well, does ATI do a P to D swap program? If it is reasonable then that,s the way to go. I still really like the idea of spinning a charger slowly to produce a given boost level, the heating of the air charge is only one of the reasons for it.

I don't think they have a swap program Greg, but I think the cost diff is about $400 between the 2. I like the idea of lower impeller speed too but if your certain that you're not gonna up the bar at a later date, the extra $400 seems like a bit of a waste
That is a good bit of difference, Well I will just say one more thing...once you start adding power, when exactly do you stop? That's what I was getting at, once you are addicted you just can't stop....you do know what I mean don't you.

moi?
I know you don't mean me. I can stop anytime I want...really.....no, I really mean it....I'm serious......well, I could if I wanted to.....
The D1-SC kit costs a little less but doesn't come with injectors. When you add a set of 42# injector to the kit your only about $20. more than the P-1SC. This would give you more room to grow into the kit when you feel that you want more power.
Going from a P1 to a D1 later would be about $1000.

Tom, is this a fairly recent developement?
When I bought my D1 a year or so ago, I saw the ATI pricing sheet for all their Prochargers and I could have sworn I saw a $400 price diff between the P1 and D1 I knew the D1 didn't come with the injectors but I'm surprised that my memory is that far off
