Metric 200 Change
 
Thinking of changing from my Good turbo 350 to a Good Metric 200
about how much quicker would it be ?

I think Chuck Norton might know, as well as who to have build it. Pretty sure that is what he used, and introduced me to his builder at Vegas a couple of years ago.

Ken,

Talk to Jack Sepanek @ 570-457-6517 ( in Pa. ), he can help you out ... How much it will pick you up depends on your current combo .. That said, I think you will find at least a tenth or more .... He does lots of T-350 and M-200 for racers in Div. 1,2,3,4,5 ... Best part is he & Kattie are both racers..
You won't be Sorry, easy to work with & knows his stuff .... Remember the Metric comes with a 2.75 first gear, did your T-350 have a low first gear ? Good Luck,

When I got my Metric from A-1 .07 was discussed. I did more than one change at the same time so not sure of actual numbers.

I do know this for sure it was worth a 60 pound savings from my t350

The 60 foots lowered ( different first gear ratio )

I used the same convertor between the two trans.

Great weight savings!

Scott McClay told me that on our big block car he would guess less than 0.03. His feelings were the less power you had, the bigger gain you see. Our TH350 stuff is all aluminum with gun drilled shafts and scalloped planetaries, so it is very light, only the ultra trick Coan stuff is lighter than what I have, in our TH350.

my coan xlt is about a tenth faster than the 200, you can feel the difference in the burn out box on how quickly the coan unit comes up to speed.
