IN all honestly, it goes like hell if I punch it....I'm not
that good a driver to squeal the wheels on my shifts or anything. I have the MSDS headers and also lightened my
flywheel when I had the P/P work done. It loves to revs, and gets to 7500 very quickly, so right away the secondaries get engaged, and the power curve is very smooth and powerful. Before the PP work but after the header work, a good driver in my car would have no problem keeping up with Mustang SVT's.
If I were to do it again, I would do the header install at the same time because it pretty much is the same work and the guys actually pulled the engine to do the head install.
I probably should have done the 3.0 conversion too but it would mean my mechanic would be doing something like that for the first time, and I didn't want to be the guinea pig.
I ended up with all the power I really need anyways.
Not enough to pay for your dyno, but I'll be supportive until you get it done!
