My guess would be at least 30# maybe more.
I never tried to calc the true difference in power potential, but by the rules we know the Iron Headed cars do get the weight break, and all cars are limited to the maximum power that a 3-bolt 70mm turbo can provide.
By the times Dave & Roy have posted so far, it seems the rules have somewhat equalized the performance potential of either type of combination.
In addition some decided to stay with 200r4s, with stock type rears, others went TH400's & 9" Ford rears. Each have advantages & disadvantages, the list goes on etc.
Hats off to those who put the TSM class together, and all that particpate. Its a very exciting class to watch and talk about.
All the racers/participants are a class act for sure.
Good Luck & Safe Racing to all at Reynolds.
