ok, Sky I sent you an email back.
Lag, yes it has some, about equal to a hx35 with a 16cm housing.
Less then a hx40 with a 16.
way stronger than the 40 with a 1mm bigger shaft. Flows 20%more than a 40 with a much higher alowed boost of 48psi( can be easily run to UNDER 60psi)
Cost is about 1/3 less than the B1 with no exhaust mods necessary so you save the 200 off the downpipe also.
Its not magic, just another bigger turbo for the guys that want to stay single with Over 400hp.
