Greetings,

 

I had a very optimistic day for my rev-2 upgrade.  First, I weighed most of the large items, and got an estimate of the difference in weight between the turbo version, and the new NA arrangement.  It should be about 54 lbs lighter!  All this weight off the nose is also great, since I was way nose heavy before.  Calculations show that the CG will move aft 2", which is just perfect!  I really couldn't have hoped for any better results. 

 

I also managed to get the initial fitting of the new cowl done, so I can concentrate on fitting evap cores, intakes, and exhaust.  This is actually the fun part, especially when folks drive up to the hanger and rave about the looks of the new cowl.  It's amazing how good a stock cowl can look :-)

 

Cheers,

Rusty (Motivated, but still a ways from the second first flight)

 

 

 

 

Some weights:

 

 

Old radiator- 22 lbs (sure thought it was more)

New evap cores- 5.5 lbs each, total 11 lbs

Difference- 11 lbs lighter dry, and about 19 lighter wet

 

Old intake, TB, pressurized air box-  11 lbs

New intake will probably be about the same, so no weight change.

 

Old 100A alternator- 12 lbs

New 55A alternator- 6 lbs

Difference- 6 lbs lighter

 

Turbo, manifold, spacer, exhaust pipe, heat shield- 44 lbs

New exhaust with Spintech, estimate 15 lbs

Difference- 29 lbs lighter

 

EWP’s, one way valves, and extra hose will probably be about the same weight as the stock mechanical pump. 

 

Cowl will probably be a wash, since the new one will also have the rear cheek extensions installed.
