I used a nice and big IC for the T25! Man that was sweet! But I think it I should have gone bigger.

With a good intercooler you should get some pressure drop no matter what. Cooler air is denser. From the Ideal gas law, in order for the same volume of air to enter an intercooler and come out the other side cooler, it has to lose some pressure.

REALLY?

Here's buschur street kit:

Indy Race Cores street core can be seen on www.turbotrix.com

RnR's core can be seen on www.rnrracing.com

Slowboys can be seen on page 1

Look at the placement of the inlet/outlets on the SlowBoy endtanks and the weird perfect triangle shape of the endtanks. That's what I am talking about,

The 1G core from Kinetic Motorsport looks very similar to Buschur's-

Look at the pipes as Ecoli mentioned... if they are near the edge its much better but slow boys are like in the middle of the triangel shaped endtanks...

Did someone delete my saddam post?

the endtanks are not perfect triangle shaped. ya the inlets and outlets are a little lower, i see what ur talkin about, but they have to be lower because the core is taller than most of the other "street" cores at 12" tall vs. like 8-10" on other street cores, and the bottom already sits right at the bottom of the bumper, here's another pic of it btw...

but anyway, who cares, im still saying that AHP's kit does not appeal to me whatsoever.

Cool, so don't buy it.

This is a pretty pointless debate as all the IC's in question are pretty much identically the same, in the long run it just comes down to the piping. IMO AHP's piping is exceptionally long and a little overdone.

Now on the other hand the comment about a 16x8 core being suitable for up to 600hp, riight. 16x8 core may be suitable for a 14b/16g other than that primary as usless as the SMIC. I'd probably rather have a supra SMIC than a 16x8 FMIC. I'd say you can never really have to big of a FMIC, the bigger the better... Now on the other hand not necessary or feasable for a 14b/16g, but who wants to run one of those pee shooters anyway.

Maybe im completly wrong on this whole concept and thats why we have such slow cars, hehe. I think for next year i got a pure genius concept of running a smaller FMIC and larger injectors, that should be the key to 10's!!!!

...and dont forget to add longer, more complicated piping because its supposidly easier to install and makes it easier to bring the car back to stock.

AHP's kit is actually about 10x easier to install...I have done both and his is deffinately easier since absolutely zero hacking is required.

The piping hacking is cake work. The only hard part is if you want to hack the stock bumper. I think it took me 6 hours to install my FMIC with short piping.

Has anyone ever done any dyno testing comparing different piping styles on the same core? I guess I don't understand what is so key about having short route piping. Sure there may be a difference rate of air temperature increase due to the pipe length increase but is the increase rate really that large?
Is there a standard composition for intercooler piping or does it vary for each manufacturer?

There will be no power difference, the only difference will be a slightly longer spool-up time. Think of it this way though, that air is moving 200-250 mph, how long does it take to move 3 feet at 250 mph (3 feet being the extra piping)? The 178 core with long(er) piping will have aproximately the same spool-up time as a 120 core with short piping. As for metals used, SS is the best since is dissapates heat better than does powdercoated mild steel. SS is of course more expensive, so its another trade-off.

To add one more thing to the piping write-up, more vendors, including Buschur, use 18-gauge piping, but AHP uses 16-guage. For comparison, most exhaust sytems are 16-gauge except for brand-names such as Apex'i and GReddy, I forget what they are.

Actually there is a HP loss to longer piping. There is a drag against the surface of the piping, the longer the piping, the more drag area. Not to mention that it has more bends in it which also cause more drag. I would want my IC piping pretty thin. Being thicker for that is just adding weight.

I am not for or against AHP. I have never dealt with them. I am just stating theory.

One more thing for piping, SS is the best choice for exhaust systems since it will hold in more heat than bare aluminized steel. Remember, you want to keep that exhaust as hot as possible without restricting the flow...thats why sometimes 3" exhaust is not the size of choice for a fairly stock car.

JET has some very valid points. One thing to remember when purchasing an IC system is the differences in end-tanks and piping probably make up a difference of 1-2 horsepower...compared to the 20-30 (don't quote me here, ask Shane for more exact numbers) it really isn't that big of a deal. One more thing to think about (yeah I know I am whoring the thread, but I feel like talking) is how unefficient the endtanks are on short-route IC sytems (thats why VPE did a redesign, too bad there welds can't handle 5 psi). I am not arguing against short-route piping since that is what I have, I am just stating many different points of view. I was originally going to get the AHP kit, but at the time I got a better deal on the Buschur kit so that is the one I went with.

I like the endtank design on the AHP cores, but the piping is just long. The endtank design on all the short route 1G kits are not optimal, but at the boost levels we run the endtank design is not all the important. At 6psi endtank design becomes more critical. SS and aluminized steel are probably the worst materials for intercooler piping, but they are the most commonly used due to cost. Mild steel is ok for heat dissipation, but it will rust instantly, so you have to either powdercoat it inside and out or use aluminized steel. Straight aluminum is probably best overall for intercooler piping due to it's fast heat dissipation and very light weight, but you don't see it used as often due to it's higher cost.
