[QUOTE="mrogerc, post: 2196837, member: 23256"] Although I own and love a Trilogy-equipped Marauder, and one kit is all I will ever buy (or, more correctly, be allowed to buy)---I am interested in some technical aspects of the ProCharger kit. That a centrifugal blower is more efficient than a roots blower is well established. Is that why you were able to use air-to-air intercooling with fairly long tube lengths? I would be curious as to your post-intercooler temperature rise over ambient. My car is a modifed Trilogy kit, and has a larger than standard intercooler radiator--it is from an Audi A6. With this setup, I get an post-intercooler temperature raise of about 30-32 degrees F. I think that is pretty good, given it is a roots-type blower. (BTW, I am reworking the routing of the hoses to this radiator--one tends to crimp, and that may be limiting efficiency, but as I said, it was not the original Trilogy part) One noted disadvantage of the centrifugal blower is the lower performance at lower engine RPMs. Actually, this is not always considered a disadvantage as lower power at low RPMs can mean lower wheelspin and since boost is lower at the lower rpm there is less tendency to knock at lugging engine speeds--something I have had to work on in my tune. Do you get a ton of wheelspin at launch? Even with Nitto 305's, I still am traction limited on all the surfaces I have launched on..... Finally, looking at your picture, it appears you have built a kit that allows you to keep the standard engine intake. That is pretty cool--from the looks of it you do not need to take off the upper intake, remove the knock sensors, etc. I like the look of your kit, and even better, the fact that you did it on the correct color Marauder--DTR. Is the intake air sensor on your car after the intercooler? Again, I would interested in seeing what your net raise above ambient is. Sometime, I would like to insert a temp probe after the blower and before the intercooler to calculate the real-world efficiency of each, but that, I am afraid, is just one of the many things I will never get to.
