Turbo for Towing

I really like my A2k! I think the ATS site says it's good to 450hp and the A3k good for 550hp. The turbine housing is so big it doesn't need a wastegate and it spins up like a stock turbo. Craig

If you want to utilize the Predator while towing, go with the 3k or a HTT 64/13ss. With that load and the extra fuel, it will still probably be a struggle with egts. A 2k or 62/12 for sure won't cool things.

Ohhh really, have you checked out an A2k? You WAY underestimate it! I don't know about the 62-12 but I know I can't get above 1225 on 100 hp and 1350 on Extreme. I did some comparing (measuring) on my A2k and Holset 14 turbines and I guesstimate the A2k is ~20 sq cm. The A2k cools terrific! I don't know if the A3k follows the same pattern IAW the huge turbine. If it does, it would also be great for the next step up. I was as much concerned about driveability as I was with cooling and boost so I went with the 2k and not the 3k. I also did the A2k and 4" before the Pred and holy cow, what an improvement that was!

I tow heavy and run a II SPS 62/12 and have had no problems with cooling and running mutiple boxes, propane, etc. I do have a Banks Intercooler through and that might be helping the EGT's a little when towing. I am happy with it and have had it on for about 45K miles. No problems and very happy about the price, got a new one off E-bay for $1000.00, a few years ago.
