I notice your truck has a Paxton on it now, pretty much the same Paxton that Paxton sells for the Gen 3 Viper. The Paxtons don't blow up the trucks because Paxton knows what they are doing.
The rear mount Turbo company, STS did not know how to tune for the trucks, they used cheap $200 turbos form china that boost surged and they did not utilize a proper charged air cooling system.
There are quite a few high horsepower gen 3 vipers running around with the same basic engine as the trucks have. My tuner has a twin turbo stock internals Gen 3 viper (exact engine as your truck) and he is putting out 800+ RWHP and has done so for over 15000 miles in the Florida heat.
A lot of people tune on a dyno jet, - BAD DECISION,
you have to tune under load for a turbo because the load causes the boost to grow, no load on the dyno, WRONG TUNE
This is compounded by the extra weight the truck has over a Viper at any given RPM the load on the truck motor is more due to the extra 1500 lbs the truck has on the Viper.
It all comes down to the tuning and a properly designed system, there is no reason a Viper truck cannot run a turbo front, rear, foot well, or in the passenger seat even, it makes no difference, it all comes down to the tuning and a properly designed system
