18psi? (Yawn!) LOL! Your GT could do back to back to back runs all day and all night!
This is the magic of twin turbos. You are barely 4 psi over stock and only a couple psi over "common" pulley/tune upgrades. Of course the BIG difference is that the engine is no longer expending energy to spin the SC and all of that energy is added to the RWHP.
*IF* you were so inclined, you could tune with some nasty C16 and crank that psi up to 23-24psi and gain another couple hundred HP. In our experience, that's about the limit of the FGT stock fuel system - approximately 1000 RWHP with TT's. Conversely, with the stock fuel system, you can squeeze 820-850 RWHP with a SC set-up.... losing a 100 or more HP to turning that big pump.
Kendall, great to hear from you my friend!
So, I'm wondering: Since it appears that I am pretty easily able to get to redline in 5th now, what kind of results will I see if I start trying to pull speed in 6th? What kind of boost do you think I would need to make that happen?
