Brain. The reason they popped a lot of blowers in the past was the Nitro mix.
I think NHRA finally decided that 90% Nitro to 10 % alcohol is a lot safer and track/time constraint/cleanup friendly.
Nitro is basically like a nitrous engine, except the air charge, etc is containted in the mix itself instead of adding the two together as in a Nitrous combo. Nitro is it's own Power adder even without a blower.
MB1966: Just make sure it's a good unit. When they first came out there were a lot of issues with them. More so then not, it was the design/quality of the product or tuner that was 90% of the problem.
