Gear ratio for Turbo aplication !
Help me beat some more this dead horse !
For what I read and know, lower gear ratios are a no-no for boosted aplications.
Lot of reasons here, but the one most builders tend to point out is loading the engine in order to make boost.
And the other main reason tends to be traction.
If we go to basics of 1/4 mile, we want to pass in the shortest time posible.
If we have a drag dedicated car, we will want to pass 500-1000rpm before hitting the rev limiter 1:1
Now, if we have a 4wd drag car, that has non to minimum tire spin, and because of it's weigth (4500lbs) and the resistance that all the drive line puts to the engine.....will it load the turbo?
Top this with the long 1st gear from the 80e.
And pretend the gear change is minimal, like 3.73 to 4.10
Will this gear ratio swap give lower ET's ?
