    I have this Garrett 3x5x7 core, but it looked like too rare an item to tear up, possibly 1/2 of some twin turbo system. Yes, I'd like to try that.

      Any reason why SC guys tend to do A-W intercoolers more than say a A-A intercooler?

        I didn't know a ton about it so I quickly searched up some Pro's and Con's of a-a and a-w

        http://www.enginebasics.com/Advanced...tercooler.html

        i think the main reason for him would be to use it at the track and throw ice in the A-W for optimal results in cooling the charged air.

          That makes sense for that application. I just look at all that's involved with a A-W setup and wonder why... Seems way to complicated for some applications. But definitely for a short run drag only car it makes sense because of the limited time the vehicle has air going over an A-A setup.

            if i had to guess, with a roots blower, i'd say plumbing issues.

              People say that but there is quite a bit of extra equipment needed to make the A-W setup work, never mind the A-W core itself. I can understand it for the application, but in my mind I would think if you can fit a A-W core, and heat exchanger and all the necessary plumbing for the water lines, tank and pump, you should be able to fit two pipes for a A-A inter cooler. But then again I've never had to try so I may be out in left field LOL

                    My guess is plenum volume. Having an a2a behind the throttle would increase plenum volume much more then a2w. Since it needs to be plumbed behind the throttle blade and to a place where it can get good ambient air flow.

                    Turbo can intercool ahead of the throttle, making a2w less desirable as it is less efficient cause it is really air to water to air again.

                    Just a guess though...seems logical.

                      Not all SC's have the TB before the blower though but for this type yes your correct.

                      for instance...

                      And this setup has a A/W intercooler and it takes up a lot of space in the bay.

                        I swear, Moses didn't put up with this much blasphemy! heh

                        Anyway, moving on, constructed a new and improved driveshaft mount and installed my straight shot UIM with transition pipe:



                        And got some runs in at Beech Bend Saturday afternoon. Nice 75-degree day, 7.5 inch slicks, bypassed filter. I forgot to have the tank full, it's been over a year away from the track, so it ran out of fuel near the end of track on each run.

                          I guess if somebody in the community really had to have a set of castings, I could probably do that, but the mounts are just in the prototype stage. They seem sturdy enough, but who can tell what could happen with severe road use. Now if one of the "Big Three" (ha), WOT-Tech, MMS, or BCC wanted to make and test mounts, that would be great, but they're not that interested in this platform, it would take their time and money. I don't have any way to make precision cuts or obtain good aluminum stock material, or even a welder. I can tell you it's nerve-wracking drilling holes in those castings lol. Also, the case mount system will most likely have to be modded for intercooling.

                          You'd have to get the SC from Magnuson Products, then make the mounts from patterns or pics. And also, a 4-inch notch has to be cut out of the hood bracing. Right now, unmounting of the SC requires removing the inlet casting, 9 bolts, and loosening 3 others. You have to do that to change spark plugs 2 and 4.

                          That being said, the effort is well worth it to me. The car made it a good 180 miles loaded down round trip to the track, got beat on, and ran effortlessly, worn-out engine and all.

                            No blasphemy, just trying to figure out why SC guys typically go A/W... that's all. And with a Roots type blower it makes sense because the positive pressure is post TB so plenum volume comes into play, where a centrifugal SC the boost is like a turbo setup.

                              Based on what I understand, SC's produce heat sooner and more of it than a TC. So for a drag car with a SC, it would be faster to cool and prevent majority of the heat soaking to occur. However, with all the types of liquid injections available, an A2W is really not needed anymore (meth/water/alky) .

                                not to drag it on but.....a2w are less efficient then a2a per cross section area. Because an a2w is actually two stage heat transfer. Air to water then back to air again. Makes it less efficient then regular air to air. That and the water can become heat soaked, where the a2a does not.

                                I am pretty sure water takes longer to heat up then air does, making a2w slower at cooling the air charge. That I'm not 100% on.

                                With the complex nature of plumbing a2w, the efficiency drop, heat soak issues......a2a is far better. Unless you plan to ice the cooler or cryo spray, even then a2a can do that too. The advantage is having far less volume needed to cool X amount versus a2a.

                                That's my take on it, not going to clutter up the thread.
