When you say it should run low 11's with those parts you are assuming he has the tires and suspension to dead hook it at high boost off the line I assume.
I have basically this same combo TE44 and its first trip to the track with Nitto 275/50 drag radials was a dismal ...
12.45@110 with a spinning 1.95 60 foot ...
most were 2.0 and 12.5 to 12.8 @ 108 to 109.
My deal and irritation is a dang new Camaro or moostang will out trap me all day long... so I am down HP...
I would love to build my car to have more mid track top end charge so the launch is less important.
Hated that dang Vette walking my butt last year from about the 1/8 mile on trapping 118 to my 110.
