Here's another pic of Allan's TR, to tell you the truth, I am not sure if this car started out as a GN or if it is a Turbo T but one thing for sure it is FAST!  9.86 at 136 mph and it IS street driven.  Allen sent me the two graphs below with a comparism of air temps WITHOUT and WITH my 4" inlet pipe and Big Mouth cold air kit installed on his car.  Look at the purple line and you will see the air temps on his runs. Air temp degrees are on the left, seconds of the run are at the bottom.  Note that he was getting higher temps on the cooler day WITHOUT the Big Mouth kit installed!

Below is the email that Allan sent to me recently.

 Mark , I ran my Buick last friday(10-17-03) and made a new best pass of
9.86 @ 136.8 MPH.  I will attach a data file that shows last years run
without your big mouth kit and this year with your kit installed. Your Big
mouth kit made a big difference on the intake charge as you may see from
the graphs. I included these paramaters to show your kit was capable of supplying
enough air for my  272 cid Stage 2 engine to about 7500+ rpm .Without your Big
Mouth kit, air inlet temps started high and as the car went down the track
the air inlet temps went down. Without your cold air kit, Temps were in the
120 range and it was a very cold mid 40 degree day. The other graph(with
cold air kit) shows air temps much lower and it was a warmer day.
