Equal length tubing, 4 into 1, short collector I'd say that possibly they have done quite a good job at a mid range power producer. I don't know how many of you have ever had a Comptech Header but I'll tell you this, their headers are impecable and the welds are damn near perfect. I ran one on my Type R. No thanks Pinky, that's another $300.00 to $500.00 on top of this cost.

I hope MikeB stops by and gives us some dyno numbers. It's been along time coming but I'm sure a very worth while wait. I've always been very impressed with their work and patiences in development. There's a lot of very pleasent folks that work there and are always ready to help and share the information.

Pinky, if you'll look at the intake on the SC it's very similar. As far as I can see it utilizes the open intake area to the left of the radiator on the left fender. Well out of the way of the radiator and the heat. With the addition of axcillas open intake panel it should breath quite well without being subjected to water injestion. It looks to me that they went to great pains to ensure maximum airflow without the danger of hydralicing the motor.

I maybe wrong calling it a CAI also!

Thanks Comptech!

 

I thought a 4-1 header was better at creating top-end power...am I wrong in this? Isn't a 4-2-1 supposed to be more effective for the midrange?

Not necessarily! This is the general misconception that goes with headers. Yes, 4-2-1 headers generally produce more torque than 4 into 1 headers. It's an overall proposition and combination. Tube length and collector length determine engine exhaust scavanging. Longer tubes and collectors maintain some back pressure for more lower range horsepower. Where shorter tube length and collector length scavange exhaust quicker and develop horsepower farther up the powerband with some loss of torque in the mid range. Using a 4 into 1 with longer tubing and collector would help to solve the loss mid range torque, while maintaining high output horsepower. I'd say this is a middle of the road approach. I think that your going to see some good mid range increases while still maintaining some good gains at the top end. I guess time will only tell.

Header building is a complex proposition. It takes time to build one which will truely enhance the overall performance of a specific engine. It's a give and take kind of thing. There are so many configurations that can be use it's mind boggling. This best header is the one which will give gains through the entire powerband. I'll bet this was their goal. I could be wrong though.

Actually, they produce some of the best headers on the market. As far as proven, it's not going to lose power if that's what your getting at. Comptech doesn't put out aftermarket parts that lose power. Generally, they're not the top horsepower producers eather. Remember, the focus is on street ability. They produce most of their parts with this in mind.

As far a porting the airbox, I think Wes is the only one that's done this to date. Like I said, I might be wrong calling it a CAI. But I will tell you this, it will flow better and stay cooler than the stock box with pretty close to the same wet weather protection. Am I hyped about the prospects.......Yep! Especially since these products will be authorized and sold at most dealerships.
