Intercoolers??????

[BLOWN HOWARD]

Curious how much an intercooler would help out my motor and, if it would make the motor last longer,What kind of HP do you get out of them and what is some cost for them also

[Infomaniac]

100 HP at least. On gasoline.
Superchiller is one that will work on standard blower manifolds. Shop around.
Whipple makes a really nice one that fits inside their manifold. Very effecient. No additional height. Not cheap though. I can get you a deal but they are way more than a superchiller.

Hey Infomaniac, since we are on the subject of a whipplecooler, I have a question for you? I have a 502 with a superchiller and a 250 B&M supercharger that I am running currently and am pleased with it but im curious to know if by changing the B&M manifold and the superchiller out for a whipplecooler would I pick up some more HP cause I would be lowering my blower down closer to the motor which should give me more boost with the same pulley im running now. Not to mention the whipplecooler running cooler than the superchiller. Am I on the right track cause if im not mistaking when you do add a superchiller you do loose some boost cause the blower is sitting higher up now correct? Than later I could add a single whipple charger to add to my whipplecooler. Thanks for any input you might have.

[Infomaniac]

The Whipple manifold and cooler will ad a bit more power by allowing you to run a bit more boost.
The additional power would not justify the cost until you put a Whipple on it.

Richard lee also makes a very good cooler?

Not quite... you lose boost pressure with an intercooler because you're cooling the air mass, which drops the pressure due to PV=nRT (perfect gas law). There is also a pressure drop due to the frictional losses of the air moving through the fins of the cooler. That fact that the blower is sitting up higher does not directly cause the pressure drop. On the plus side, you do gain density with the drop in temperature, so the net effect is increased HP because the engine has a larger air mass to work with. A more efficient blower like the screw compressor will produce even more HP gains because it creates less heat and less mechanical loss (HP consumed) to produce the same boost level.

Did you get any of that JBB??? :)

While on the topic of intercoolers----
Finally got my engine together and took the procharged 454 hallett bubble deck down to the river to try it out. Well the intercooler which was supposed to have been pressure checked by the OEM (per the previous seller) sent water all through my intake system (carb enclosure had about 1" of water on the floor) and otherwise nearly hydrolocked my brand new motor. $@#*
So I call the worst customer service outfit on the planet (you know the outfit Procharger) and get put on the tech line and wait and wait and then wait some more until I get one of their top notch yahoos on the line. I explain to him my problem and ask if I can get an envelope drawing for the different intercooler configurations that they offer so that I can place an order for a replacement. His response was that they don't have such a thing and that what I was asking for was an engineering drawing which is proprietary. How absurd is this? I'm about to drop $1200-$1600 for an intercooler and they can't even give me the courtesy of a paper napkin sketch such that I can order the correct item. After finally convincing that genius that maybe he should fax a hand sketch so that I can place an order I wait for the fax and wait and wait and wait...... and never get anything. Beyond that I also ask him to fax a listing of local distributors so that I can do business with them and nothing......
Knowing that GS marine is involved with them I contact overall good guy Greg Shoemaker and place an order for a unit which should be a standard replacement for the kit that I have. Greg does his thing and I get the part well it's not the same as what I have so Greg and I get on the phone with Dorian who is the only helpful guy at Procharger and start the process all over (that is of getting a dimensional drawing of the different intercoolers they offer to compare to the one that I need). What a big waste of everyones time, shipping expense, frayed nerves, etc.....which could have been avoided if Procharger would just wake up and realize that people don't want to do business with an outfit that makes you wait on the phone foreeeeeever, doesn't fulfill their promises (about a simple fax with model numbers vs. envelope dimensions) and makes it as hard as hell to place an order.
I wish I had spent my money with Whipple, BDS, Mert Littlefield, Mooneyham any one else but the undisputed leader in bad customer service.

Infomaniac and Doghouse, Thx for the info. I really appreciate it. Info, Have you ever ran a single carbed whipple set up berore? If so do you have any pics of the set up or any thoughts on what you thought of it. Thanks again. By the way hbhallet, sorry to here all the BS you went through with procharger. I went through the same shit 4 years ago and now im just running a little B&M 250 for now. Dont get me wrong, prochargers work really good but I guess its just preference. And yes customer service really sucks with them. Someday I would like to switch over to a whipple!

My homemade intercooler has worked out pretty well so far.

I pressure tested the core with 40 psi water pressure before I installed it and have rechecked it with air pressure a couple times since.

The core was a new heater core from a bus and cost me $ 50

Unchained hows the boat running?

Mark, Have you measuered how much it drops your temps?? And do you know the pressure drop across it?

Mark, Have you measuered how much it drops your temps?? And do you know the pressure drop across it? [/QB]I don't have a pressure tap above the intercooler, only one below it, so I can't compare the two. The ECU has a data record function so that you can read what the engine has done for up to a 4 minute span and that's how you can review all the sensor readings and what point on the fuel map you were running on.
The readings that I have gotten on the air temps below the intercooler are in the upper 90's but it seems that to get a true efficiency reading you would need to have a steady load and high boost for maybe 15 seconds and that would only be possible on a dyno. Even when I ran the boost up to 20lbs the air temp reading only went up a few degrees because it was only for a few seconds. The intercooler full of lake water resists changing temp quickly and mine probably has more water and fins than most.
I just changed the cam to try to calm the engine down a bit. It want's to run right up to 20lbs+ boost at 5000 rpms and that is higher than where I wanted to run at for fuel map adjusting. That has prevented me from making full power passes.
Also I have had a number of small problems that needed to be worked out.
Had to go to shielded cable from the MSD to the coil because the signal was affecting the ECU.
I've had to add some additional heat shielding around the headers and the turbo's.
I found that I have to shoot raw fuel into the scoop to fire it the first time of the day because the mechanical pump doesn't make much pressure at cranking speed. On the off season I intend to hook up an electric pump to the fuel pressure line that will turn on with the starter and put some pressure in the system. After the engine fires the fuel pressure comes right up and is good for the day.
Mostly I've had a learning curve on the fuel and ignition maps.
I seen the pictures that you put up of the Turbo'ed ski race boats, Were those guys all running EFI?

[Blown 472]

What keeps the fuel from puddling under the intercooler on a pull thru carb dealio?? also wouldn't the air in the blower get hotter due to the restriction from the intercooler??

[NoGoSlo]

I had my superchiller leak like hbhallet. It was under a Littlefield 6-71. If you run a superchiller, be careful to limit the water pressure. I did hydraulic my motor . . . http://www.***boat.com/image_center/data/520/914Early_morning_2X1.jpg
