Intercooler pipe sizing and spool/ turbo efficiency
#22
I have a question as well, I have a b6t Festiva with a rear mount setup.
2.25 exhaust back to the vj14/t bird hybrid, the turbo outlet is 2" and I have it stepped up to a 2.5 to the meter (which is stepped to a 3") then back down to a 2.5 which goes into the TB.
Now I'm curious as to if I went to 1 7/8 exhaust wrapped with heat wrap and 2" IC piping would it yield faster spool times? I currently get full boost at 4200 which I feel is a little late.
Discuss?
