I have a 07 HD saleen charged f150 and am putting a nitrous shot on it this week. What can this truck handle? I was thinking around a 75-100 shot max before I got into the redzone. What do you guys think?

 

Stock engine internals can't handle (safely) more than about 425 HP to the wheels. You're pushing you luck with 75+ with the supercharger --- plus you need to get it tuned for the nitrous.

 

I tossed the 100 shot on their yesterday and the truck runs like a champ...I should be somewhere around 430 to 450 at the tires respectively with the exhaust and JDM tune...we'll see how it works out!

 

Are you willing to bet your piston rings on this because they aren't designed for it and can fold. Is the JDM tune written for nitrous (needs to pull out 2 degrees of timing for every 50 HP shot)?

I'd be very careful unless you do work on beefing up the engine, or its not going to last long.
