The VT1 4.5 psi kit is normally about 45 degrees hotter than the ambient temperature just driving around normally. However, once you get that blower to working things start to heat up. If you go to WOT starting in 1st gear by the time you hit 5th gear the incoming air is now 77 degrees hotter.
I upgraded my VT1 kit to the 5.5psi pulley which added an additional 10 degrees.

In other words, run the VT1 on the track at your own peril. If I was going FI it would definitely be the VT2 kit.
