I currently have the twin intercooler set up and I wanna upgrade it to the big single ...the question is ...how will that benefit the vette ..the car put a lil bit over 600 rwhp through an auto.....on 12.9 psi (built motor with heads and package and a few other goodies...will the car make more horsepower and run cooler? by pushing more psi ..I currently have a 3.45 pulley on the d1sc

my other question is since I'm thinking about upgrading to a single how much might i be spending? and how much could i get out of my current setup?

 

I have a big single with two inlets on it that might allow you to plug and play with your existing setup. Depending on what you're trying to achieve this might be your best route.

 

I don't know how much you will gain! That depends on the efficiency of the intercooler(s). But the cooler you get your air, the denser it is. The more denser the molecules, the more molecules you can cram into those cylinders for a bigger bang with the same boost. I think a big single intercooler could go for $1k easy. Unless you know how to weld and you purchase a core and build your own.

 

Over 10 psi you really need to cool inlet charge down so get the most efficient set up you can. Dont forget if you make more power your going to produce more heat so you might have to do something with your cooling system. I run 8psi daily driven zo6 and when needed spray 50hp shot of n.o.s in her throat and across the cooler which makes a 90hp difference on dyno. I reciently relocated my cooler in my front license plate area so it wouldnt block the air going to my radiator plus with the blower I ditched the vararam for a better filtering element and there's two more spots for coolers.

 

When it comes down to intercoolers it’s about pressure drop as much as cooling. If you cool very well but take a 3 PSI pressure drop with piping, then a single takes 1.5 PSI pressure drop with slightly less cooling, which comes out ahead? Usually single! But then it depends on final goal. Without being specific it’s hard to tell.

A good example is 6 HP per pound of boost at 60 lbs/min. 3 PSI loss equals 18 HP or more to drive supercharger.

You have to look at total package.

That would be a pretty neat kit! A single IC with dual inlets and some piping to mate it to the stock ATI twin pipes. I can't exactly picture how it would route but neat just the same.

 

How is your intake routed?
Is it a large tube over the top or are you using the ATI filter behind the radiator?

 

Amdy's kit really works great!!!

 

Who is Amdy?

Sorry, couldn't resist.

 

I made 13psi with a 4.10 pulley on my d1sc with heads and cam. does that tell you how much better the flow is with A&A's intercooler? it's always good to make more boost with less pulley. less pulley = cooler iat's at a given boost level

 

It's hard to associate boost levels and power. An example is if you added long tubes and loose the cats your boost will drop but you will be making more power and running more efficiently. With respect to the intake side of things you're looking for the intercooler(s) that will reduce the intake charge temp the most with the least loss in pressure becaue if you do something on the intake side that reduces the boost pressure you're restricting flow and loosing power assuming power lost by the pressure drop is not offset completely by the temperature drop.

I don't think I've ever seen these type of imperical numbers from either the dual or single intercoolers that are available (IE: intake charge temp drop and pressure drop). Also most people who switch to a single FMIC tend to go from the ATI flat, behind the radiator air filter to the over the top and in front of the radiator filter when they switch from dual to single FMIC and a lot of power/efficiency appears to be gained from the intake change/relocation alone so it's hard to tell how much power you'd pick up if you already have that and just switch to the single FMIC.
