Direct Port...Waste of money on stock motor?
This may just be internet gossip, but I've read that its not advisable to spray more than 150 on a stock motor (4.8 in my case). Nitrous is something that I'm just starting to get interested in, but I'm wondering if direct port is more for higher shot/hp applications and if I'd be pissing money away on it compared to a plate kit with my application?
P.S. If I were to go direct port it would definitely be on an aftermarket intake manifold...Pro-Flo XT more than likely.

Just various conversations I've had with people, the way the truck intake manifolds are designed they are not meant to flow fuel, and puddling can be an issue. What I've been told is that once you get over a 175ish shot the dry intake can start to be a pain in the ***. So really two options for big shots, a carb style intake with a plate, or a direct port. There is quite a few stock bottom ends running around on a 200 shot by the way. Just takes caution, good tuning, and GOOD PLUG READING.
Oh and nothing looks more bad *** than a direct port.

The direct port is for more serious applications. The reason for the direct port is that with the nozzle in each runner it gives perfect distribution no matter what jetting is thrown at it. Also having independent jets per cylinder allows for cylinder to cylinder tuning which is again, a huge advantage when you really step up in jets.

I like the way you emphasized plug reading. That is the best advice that can be given.
