BPD HD cooler and 155s towing review
I'm in flagstaff AZ, Vegas tomorrow final destination, started in WA DC. Did the same trip with same load (reverse direction) with OEM fan, injectors, and BPD standard cooler exactly 2 years ago. The load is my 40' toyhauler that weighs 14 empty, with a 3200 lb car, and 2500 lbs of household items and tools. Ill weigh it tomorrow but I've towed the load many times its right at 30k. On my trip two years ago I has no issues with EGTs but did run high EOTs. Seen 240ish a good bit and got up to 265 on a long hard pull. Over the two years in DC I did some mods to try to fix this for return trip. I added 7.3 fan (BPD adapter) BPDs HD (taller) cooler and a mesh grille to promote higher airflow. I also added 155/30s.
I have now pulled across near the entire country and can say the BPD HD coolers are the end all be all, period. Same sections I flirted with 250 I was running 220. Highest EOT seen yet is 228 and that's long grades at 50 mph where it's toped out, the cooler is amazing. Combined with my 7.3 fan and mesh grille, overheating is a thing of the past. It's such a huge differance then last time I'm sure I could of kept the OEM Fan and grille and would of been fine. Thank you Ken and BPD my overheating issues are behind me.
Now the 155/30s, mixed feelings. In running a "heavy tow tune" with fuel pulled from the 155s for this heavy load. DC all the way thru TX no problem worked great, but in NM the elevation across the entire state is 6k, for whatever reason this is not good for the 155s, I have to monitor them and in OD could rocket past 1400 if I tried. I'm babying the throttle to barely squeak out 65mph at 1200 EGT (for hours). Just checked motor tonight and didn't melt anything, so I've proven you can run right at 1200 for two hours straight. I would just drive to keep pedal pressure to maintain 1200 and this got m 65 mph give or take. The speed limit is 75 but I can't get there. Before NM and the high elevations, 1100 EGT would keep me at 70mph all day long. So I have mixed feelings, yes you can tow but I feel I could of had more power on stock sticks in NM. Ill drop out of 6-7000 feet tomorrow and leave these worries behind me, but you guys that live at altitude, I'd recommend against.
I can't say enough good things about the BPD products, my truck runs like a champ and once again gets my Fam and toys across the country.
