Mass Weight of ProTrans?
 

Looking for some info on the total mass weight of a ProTrans in an effort to calculate weight savings against a TH400 (JW Bell Housing/ Alum Drums). Any input will be appreciated.

Re: Mass Weight of ProTrans?
 

I believe the lowest mass racing transmission in the market may be the Coan Racing XLT line of transmissions which have a smaller diameter rotating assembly with billet components.

TCS Products in Canada makes a lot of the billet components that are used in the ProFlite transmissions.

Protrans 350 w SFI bellhousing and cast pan 110#
TH400 alum drums stock bellhousing 135#
Coan XLT with SFI bellhousing 115#
TH350 alum drums gundrilled SFI bell 125#

Weighed all of these except Coan, got info from racer who weighed it.

Awesome, Thanks guys!

If you like I can weigh a gear set and a sun shell & all that rotates for the Pro flite.
I have one apart right now.
I can also make you a deal on my spare, almost any ratio you want.

I will try and get the weight of a Kilgore Superlite .

Re: Mass Weight of ProTrans?
 

sure more options the better.. Ive never looked too far into proflite or Kilgore. How do you like them?

Re: Mass Weight of ProTrans?
 

I run a Kilgore in my GT/FA Formula with a BBC. I also run a Protrans in the SS/DA Coronet . Both are high quality transmissions . It would be neat if someone would build a SFI case for the TorqueFlite !

Re: Mass Weight of ProTrans?
 

That would be cool. A while back I saw a project to do a 727 but nothing since. Never seen anything for a 904. I would love to no longer be a CSR customer.

For fun calculate the mass correction factor per gear.
