C4 Ati Procharger/ Intercooler
Im getting ready to buy a ATI supercharger for my 88. Can anyone give me some feed back on this unit? The car is a stock L98, Flow master exhaust from front y to tail pipe and upgraded ignition coil. Auto trans, factory 3.07 rear. Im looking to buy the 8 LB boost kit with the intercooler.What kind of gains can I expect. Is it REALLY worth the cost? Can anyone recomend a ATI Procharger dealer? If you know of anything I should purchase with this this kit, please let me know. Thanks,Mike

Give Greg at blowerworks a call or check out the site www.carrollsupercharging.com. I spoke to Greg last week about a s/c setup for my vette. He is very knowledgeable on the subject. He's also out in NJ to.

Greg is the man! www.blowerworks.com his number is there... feel free to tell him Mo sent you as well.
With 8 pounds of boost, take your HP and multiply by 1.54 that will give you a rough Idea...
So as an example, 245 * 1.54= 378 hp roughly make sure your trans is up to the extra power...
hope this answers your question...

Proper way is to rebuild your engine for boost and THEN add blower.
Take it from me.
You won't be dissapointed in the performance, but I'm speaking dollar for dollar w/ respect to reliability and tuning issues you will have.

I want to start out by saying that I'm in no way bashing ATI, just commenting on what I have heard and read. There was a member, LT1Vetteguy78, that was not too happy with his ATI setup after spending a lot of money on it. Greg was able to tune it for him and get a few extra horses, but overall he spend a considerable sum (I'm guessing over $8k). Greg himself will tell you that the ATI kit is not the greatest and will steer you in the direction of his modified Vortech kit.

All I'm saying is be prepared to spend at least %50 additional than the $4-5k the kit costs initially.

What you try to save up front, you have to spend once it is installed. You generally get what you pay for. I have found that setups straight from vortech, and what I have heard from ATI. ight be fine for an occasional "romp" but if you are serious aboutt he perfomance you are ging to need to invest in more than just the kit...
Gregs products may "appear" pricey, but the are complete, well documented and are well thought through... priceless! I hate having to run to the parts store in the mddle of a project!
Logging software, programming software... widebands... perhaps fuel pump, injectors... Depending how far you want to take it... and that does not count the parts breakage that comes with more power.
HEH But that is all in the risk of the hobby...

Hey Mo, I haven't been around in a while, I think you said you were getting a Carroll Gaseious Intercooler, I see in your sig you did. how's that working out for you? How much money and time did it take?
Sorry to get off topic.

hey vvv90,
I'm doing great thanks, broke my transmission
Yes, I bought Greg's Gassuoues "plus" version which has a switch in the cabin to turn it on or off.
It have been a TREMENDOUS help! I've ben able to trim the fuel back and increase the timing... it is putting me over the 500 HP mark...
Taking my time, I'm using my washer fluid container it took ~ guessing~ about two hours, as I rerouting things . As I recall it was like 395, my opinion the best investment I have made!
I was doing some testing with a 50/50 methanol / water mix and took out second gear again. So the trans is on its way to be TOTALLY rebuilt and beefed up!

My pleasure any time 
Sell your ATI Intercooler and get the deluxe unit from Greg! I had bought a ATI intercooler early on and had it installed, there is no comparision... The water injection is far superior.
If I'm not into it, I generally top off the Water / alky or Meth per tank of gas... I use distilled water and 50 % methanol. I have it kick in about 3 pounds of boost. I was leterally seeing 0 knock with 10 pounds of boost, and an estimated 522 horse... and a couple peaks to 540 pulling almost 800 CFM. I was starting to exceed that when I broke the trans HEH, I orginally was resigned that I'd be happy with 450 horse...
well once I got the water injection in I quickly surpased that. I had the trans built to handle 450 horse, it is now as I mentoined going in to be built to handle 700 even though I will be pretty much around 540 since the engine has all stock internals. I might add the 540 was at 5500 rpms.
I'm planning on getting another block and starting to build another engine as I know eventually HEH well you know the story...
Everyone is telling me trade it, get a ZO6 I'm like well... I have the car where I'm liking it now , why start over? HEHE

Holy Crap! That's by far the highest gains I've heard from a stock mill. Dayum that's awesome. Do you have long tubes?

no I'm using stock manifolds...
Estimated , I'm showing on my log runs I'm averaging at 6100 rpm 56.47 lb/min of airflow..
56.47 *14 = 790.58 CFM Using a rule of thumb 1.5 CFM per horsepower
790.58 /1.5 = 527.05 Hp
527.05 /12 pounds of fuel = 43.91
I'm running 36 pound injectors at about 60 pounds of fuel pressure.
With the Methanol I'm hedging 12 psig of boost right at the shift...
12 pounds 14.7 atmospheric pressure = pressure ratio * base hp
11+14.7 = 27.7 /14.7 =1.74 * 300 = 524.48
12+14.7 = 26.7 /14.7= 1.81 * 300 = 544.89
I'm running 18 gallons per hour of 50/50 water / methanol mix...
