Re: Considering switching from H/C to S/C, any suggestions? the D-1 is like $300 more than the P-1
D-1 can support more power and is supposedly a little higher quility
gas mileage shouldnt change
and thats a bout all i can tell you since i dont actually have one yet <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />

Re: Considering switching from H/C to S/C, any suggestions? Well I spent $139 to upgrade to a D1. The reasons I did were that I heard a couple of people complain about the P1, but no complaints about the D1. The D1 is more efficient, making more cfm per rpm. And when I decide to go bigger the D1 will more easily grow with my increasing boost needs.
As for gas mileage, I haven't installed mine yet, but my suspicion is that you will lose a lot of mpg unless you drive her very responsibly, which will be tough when all that power is at your foot <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> But keep the RPMs down and you won't notice much of a difference. Highway driving shouldn't be drastically effected.

Re: Considering switching from H/C to S/C, any suggestions? I know most people here are die-hard proponents of the ATI D-1SC. But I'm very happy with my setup. I made 536RWHP at 6600RPMs and 8PSI, running out of fuel injector. And I still have a little room to grow with a smaller pulley, bigger injectors, and a forged bottom end.
I know I won't make 700 godzilla RWHP, but around here, there are very few folks on the street who can mess with close to 600RWHP, 4.10s, and slicks.
Not to mention the Vortech polished kit is a VERY pretty kit. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Considering switching from H/C to S/C, any suggestions? Crunch,
You made 536rwhp on stock injectors? So I am guessing I won't need larger injectors right off if I have an S/C, small cam and headers.
Also I noticed that the ATI kits are priced in the low $4k range and the Vortech (aftercooled) are in the mid $5k range.
Why the price difference?
If I get the ATI race or tuner kit, what else will I need?
I have LS1 Edit already.

Re: Considering switching from H/C to S/C, any suggestions? I have the ATI D-1SC, I liked the vortech too, but was more impressed w/ATI's setup...
I also wouldn't want to be pushing it w/maxing out the injectors....I would go bigger to have the extra security that the fuel will be there.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">When you add in the cost of new fuel injectors, and a new fuel pump, the price is roughly the same. However, Vortech did increase the price of the LS1 kit by a few hundred dollars in February. This may account for any price difference.

Considering switching from H/C to S/C, any suggestions? Right now I have a mild H/C set-up.
224/222 .568 112LSA and CNC heads, w/ MACs, stock pulley, stock LS1 intake. It made 385hp/380tq untuned and w/ an A/F of 14:1.
I just bought LS1 Edit.
I am considering selling my heads, cam and other stuff and buying an S/C. (I am tired of piddling around)
I am looking at the ATI P1-SC or D1-SC.
The car is a daily driver. I don't plan to do any drag racing (well, maybe once a year) but I do go to a couple of open track events (road course) each year.
I have searched on the board some about this.
Is the D1-SC only a $100 more than the P1-SC?
Approx. how much power would the P1-SC make with a mild blower cam, MACs with O/R Y?
What are the pros. and cons. going with the P1 vs. the D1?
How's gas mileage with a blower? (don't rag me)
What all will I need besides fuel pump, injectors, boost and fuel pressure gauges and tuning?
Sorry for all the questions.

Re: Considering switching from H/C to S/C, any suggestions? So,
If I go with the ATI D1-SC, I'll need bigger injectors, in-line fuel pump and also maybe a larger intank fuel pump, and of course tune it with LS1 Edit.
What else? Are the stock cooling fans enough?
I don't want to buy this thing and then realize that I have to spend another $2k to get it right.
I want to figure out what everything is going to cost up front.

</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">I think the stock fans are good at least initially. In hotter climates that see a lot of 100+ degree days, you can upgrade to spal fans. But the ATI kit already comes with it's own fan and that unit is fine for most applications.
Other things that you might want to consider are spark plugs(NGK TR-6 or Autolite 103s, ~$15) and maybe even a Boost referenced Fuel Pressure Regulator(Aeromotive and Weldon make nice ones, $120-150). Don't forget gauges. You'll definitely want at least a fuel pressure gauge(~$170), then most people get a boost gauge($70-170) and Air/Fuel Ratio gauge(~$50).
That's the extra stuff I had to buy for my ATI install. there are some extra hidden associated with FI installs, but I think you got the basic's now. So you can get an idea of what it will cost. Good luck with your install.

Re: Considering switching from H/C to S/C, any suggestions? I don't believe you have to go with an Intank FP and an Inline. One or the other should suffice but I'd recommend the Intank route. I'm about to replace my inline with a Walbro 340 tomorrow. The Inlines are noisy and although do a good job it's usually the stock intank pumps that can't keep up and later become a problem.
