K, so 7.5 and 4.10s it is.

 

running nitro in ur V6 is about one of the worst boosts out there for it. might as well poor acid right into ur radiator and save some time
go with a better alternative nitro from what ive seen at tracks will kill ur car after u run it to death

 

There are several V6s running Nitrous on here and they are doing it safely with no damage to there Engines. I think it just depends on how much of a shot and how you run the car. 75 Shot can be run on V6s with no issues.

 

the people around here do drive the life out of their cars, i guess ive never seen them done properly
