The problem is the D-1SC can be purchased with the tune. Bob

So, I asked this in another post but not answered. The D1 has more cfm so I can turn it slower to start, at 7 psi to work with the supplied tune, will my discharge temperture be lower? If so, that's better protection and room to tune? If not, and I don't plan on heading for 500 rwhp or more, what is to be gained?

At only 7 psi I doubt the difference would be enough to be considered. It's a mute point though as the D-1SC cannot be had with the included tune from ProCharger. Bob

Thanks again Bob. So with the P1SC, how much boost can I get with the supplied intercoolers before the discharge gets too hot?

You're welcome. The blower that comes with the 1GJ213-SCI kits these days is not the P-1SC, but is a better P-1SC-1. It is more efficient than the P-1SC. This kit can be optioned with the larger 4.5" twin intercoolers and it will still come with the tune. The 3.5" standard intercoolers do a good job, but the larger 4.5" intercoolers certainly help if you out in the mid day heat of a hot day. Bob

either the p1 or d1 go with the 8 rib kit , if you are buying new the d1 is almost the same price and make sure to do the 8 rib kit right off the bat . The 6 rib isnt worth it .

The eight rib is a very good way to go but it requires buying an ATI Performance Products harmonic balancer pn# 918853. Back in 2002 my '99 Z28 had a D-1SC 6 rib kit with the 3.5" intercoolers on it, as the 8 rib and larger 4.5" intercoolers were not offered until around 2005. At 7 psi of boost I did not have problems with belt slippage. We kept the same blower belt on it for several years without having any problems with it.
I'd say it depends what your future plans are for the car, plus you can always upgrade to the eight rib down the road. Bob

Bob, do the 4.5" IC hang down lower than the 3.5s ? I am concerned about speed bumps and being able to still get under there with a floor jack? Thanks, Les.

The difference in height is very minimal, I doubt you would notice the difference. Bob

Hi Bob, this kit comes with a booster fuel pump, do you recommend this? I have researched changing out the in tank for a higher volume pump, seems that cutting the trunk is the least painfull and allows better access should it ever fail? It would also seem that its one less thing to fail down the road and lean out which is even worse! Les...

The Booster pump works just fine, and supplies enough fuel until you get up closer to 550 to 600 rwhp. Take a look at the gauges I have in the links below.
The fuel pressure gauge is a very useful gauge as if you get use to looking at it you will see it being around 58 to 60 psi at idle, then dropping down to around 54 psi at wide open throttle. If you started to have a fuel pump problem, the pressure at idle and at wide open throttle will start to drop. This gauge can alert you to a potential problem before it causes any problems.
The boost gauge is helpful because at first the added power is going to seem to be a huge power increase, but as you get use to it, you'll wonder if you're still getting as much power as you first did. This gauge helps to let you know if you're getting any belt slippage, which more than likely you won't be. Bob

Right on, I was told that the booster pump is noisy and one other thing to fail, but if its not then I may consider using it as I am not planning on going over the kit design. After reading the install manual you sent me, I see that the balancer is torqed to 40ftlbs, I guess because of the aluminum SC pulley. Should I pin the crank?

Tighten and torque the new crank pulley center bolt to 40 ft/lbs. Now turn the
bolt an additional 120º of rotation (1/3 of a revolution). Verify that the face of the ATI crank pulley is now parallel with the face of the factory harmonic balancer.

I always recommend pinning the crank. Thanks. Bob
