my tial aint all that loud.... 50mm valve on a t25 is overkill....i get quite a bit of surge than a soft pshhhhh from the tial..... ive heard it on large turbos and its much louder..... ive been contiplating switching the hks ssqv on my t3/t4 sr20 to the drift car (t25) and the tial on the drift car to the t3/t4 car....it would make sense.... the hks is more reponsive and the tial can take anything!
