ill just get my buddy with a 99 cobra to take out the RX7. hes has over 500hp to the wheels N/A...lol.
The highest hp n/a stroker I've heard of has 430rwhp. I can tell ya right now that if your buddies car has a stock intake it's rwhp is more than likely less than 400rwhp. Sounds like your buddy is the one blowin' smoke.
