Dynoed my car before I broke it.

No, you wouldn't want to use it, unless your running 3" or bigger intercooler piping also. The butterfly is about 80mm, the inlet OD for a couple is around 85mm. The MKIV Supra guys have started to figure out that they can use them also, so they might start getting more expensive, but I paid $50 for mine. I am hoping it is a bit stronger than the BBKs and Accufabs that tend to break a lot on high boost cars.
