The Forge is great if you want to pick a fight. I have the Forge with Cobb intake and Cobb turbo inlet. Load up the boost and let off when you get next to the someone. It's loud and will scare them and or piss them off. I enjoy doing this. Got a stang GT pissed Saturday, he thought he was going to teach me a lesson.
How did you teach him a lesson? You have an SRI and at race pipe, but still running the highly restrictive DP and first cat? No MBC or tune and you beat him? How old was that Mustang GT?
Not saying you are wrong, but that must have been an older GT or was a 6 cylinder with GT markings, or had someone behind the wheel who couldn't drive the thing.
And since you are "getting next to" a car that is quicker from a dig, you would have to pull really hard to make up the head start he is going to get due to our poor traction and fwd layout.
I do not care for the Mustang GT. Would not own one. But it is a NA V-8 with rwd. It is very hard for us to pull on that configuration from a dig.
