[QUOTE="fl-krawler, post: 731063, member: 884"] I don't have a lot of real estate to for a radiator. The portal setup, combined with a lot of uptravel leaves little room for a front radiator. I really didn't want an elevated radiator above the belt line of the chassis , due to it limiting visibility, plus it raises the COG. Being a 4 seat buggy, I'm trying to keep the overall length of the chassis as short as possible with keeping enough space behind the backseat for a cooler and tool bag (20lbs of **** in a 5lb bag). I also have to fit a 15+ gallon fuel cell somewhere in the mix (my LSA is thirsty). I went back and forth with running a radiator behind the back seat, and fuel cell in the dead space behind the front seats and belly. Even at the rear of the buggy, a 26 x 18 radiator was going to be about as large as I could fit, and then I would lose my ability to carry a cooler in the back unless I mounted them high. I was also worried about being able to keep my engine cool. I've since settled on putting the fuel cell at the back of the buggy, and running two 22 x 19 x 3 radiators mounted horizontally under the front seats as low as possible in the belly of the buggy. They will draw air from the cabin area, and I plan to duct the hot air out the back of the belly and downward. A surge tank will be the high point of the cooling system under the hood. Currently the plan is to mount my steering and engine oil coolers, as well as a air to water heat exchanger (for the supercharger) at the front of the buggy, then the radiators and trans cooler under the front seats.
