Cool thanks bud so driver / driven. There abouts 1:1 will let you know what the et 750 ones are tomorrow

I bet it's 29 : 38 on that 750

So the 750 is 38/29 1.3:1 and the 1100 is 34/33 1.03:1 how much difference does it have on pressure. I can see it will spin about 30% faster. The efe runs at 4psi i think what will this take it up too

if i remember correctly about 8 psi

2.8 to 5.6 psi std
