I must admit it amazes me how badly you people can complain. Last I left off HP gains are good. I guess I'm wrong! Everyone here wants more products for the msp. Right? If all you do is flame the new products then wtf do you want. Why in the hell should anyone even try to come out with new products. I have been running a protype manifold on my pr5 for 2 months now. It is N/A and let me tell you it is worth the money. On a N/A engine the engine growls and it is a awesome sound. As far as HP I can beat the fuk out of civics oh and 1.8t vw's. not bad for a former stock 97whp station wagon. If any one has removed the manifold I think you will agree that is has a lot of room of improvement. Cullen did just this. I was there when he did the dyno. It was around 2:00 and hot as hell, 97 degrees out and the system was heat soaked.The fan hardly worked and the garage was closed up till we got there. Even with this the car ran 201.9 whp. You can argue and b**** all you want but there are gains involved. Also the baseline that was used was ran 3 months ago at 187 whp. The car has had no other modifications done. It was about 82 degrees then. So say what you want the number are there. The most impressive thing is the curve. The car pulls and pulls. You will fill a difference. I drive these cars every day. I even took a engineer from Japan out in my car and he said this is how the car should have been built. Well it was more like (with a Japanese accent)mazda need build car like this...Can I take car home with me...Gotta love the engineers...Well that's about it......... let the flaming continue and the ignorant bs start. Thanks
