Its a generic W2A. i havent datalogged it yet, but noticed a huge difference. Mainly in performance. It FEELS like its flowing 200% more air. I noticed a little bit of boost lag, and alot of surge lag. It stays fairly cool (to the touch). but once its heat soaked, its done. you gotta stop and let it cool down. I put the system together hoping for better airflow, and i believe i hit my goal.
I had it sitting on the shelf for about a month, then i broke my distributor so the truck had some downtime, and i put it on. When i park it for the winter, i'll make it all hardpipe and get rid of all the silicone fittings.
