cbmax CB a couple of things, First the exhaust is causing you about 20-40 hp. If you want race pipes ERA will build you a set. They are Loud and give ringing of the ears without ear plugs. 2, drive the car for a while and break the engine in slowly. I have 358hp and 467 tork. I have placed high in the R&G in street tires the last 3 years. 700hp is not what you want. Joe has made you a like motor. Stay off the 7000 rpm rev limiter and you should get many seasons of enjoyment out of the car. If you are going for more power take a hard look at the tork numbers, don't worry about HP. Tork moves the car froma stand still, not HP. 550 hp and 650 hp is about all the power you want unless you are a PRO race car driver. This car is quick and unsettling to drive, it's faster than you. Start with what you have, then if you need more build another motor for MAX CRAZINESS
