You need to tune for the smaller pulley. You can’t just slap the smaller pulley on there and expect to instantly make more horsepower. You may or may not need larger injectors as well. Who’s cobalt was it? ---

Moreso than the injectors but the supply of fuel like the fuel pump. If injectors are an issue, you could increase fuel pressure or buy new injectors. Be careful even with the WB02 if you suspect fuel issues. If might look good until it leans out for a split second at high RPMS. I’ve pushed my fuel system beyond what most people do (I’ve ran like 18V to it) and noticed that I’d lean out for a millisecond near peak power and barely noticed. ---

The new owner destroyed the tranny within the first week. I guess 8K dumps can do that to a stock tranny. ---

Honestly, Morgan at Synapse knows his shit especially about turbo Hondas. Stop by and show him your setup. At the very least, you are on the right track with some sort of datalogger/WB02/etc… so you can monitor. After I dynoed my car, I had an idea of what AFR/timing I could run and then I was completely comfortable tuning my own car (conservatively) and never worrying. ---

Not 100% but someone here will know. Regardless, for a honda, there is none better in this area and they have a good repuation. Talk to him and see what he says. Can’t go wrong. ---

It depends. If you already have tuning software it is some where around 450-500 ---

Unless he’s missinformed and thinks it’s the actual crank pulley too? Or unless I’m retarded and am confused by all the confusion going on in this thread. ---
