that looks great. i'm really impressed by the custom MAF. that was one thing that concerened me about the other requiring an adjustment to be made after installing the intake.
awesome find scott.
very impressive.

I wonder if that included a reflash. Like others have been saying, no mods are gainful unless a flash is included. At least the gain won't last long anyway.

The computers on these vehicles actively monitor the air/fuel ratio under normal driving and make adjustments only under part throttle and normal driving conditions. The wide open throttle strategy is not constantly being adjusted to "undo" your gains. If this were true, then your air/fuel ratio (stock) would be at the commanded 12:1 that the computer is set up for. In reality, the stock air/fuel is in the high 10 to 11.0:1 range. The calibration of the CNC machined air meter housing makes sure that the air/fuel goes to the (low 12:1) range that the computer is programmed for from the factory. We could make it leaner, but then it would cause you to need tuning as you do other mods (like exhaust).
I have been spending a fair amount of time talking with Diablo Sport about the development of this kit, so I have been given some great tips on how the computer works from them. They have already tuned a vehicle with a supercharger, so they have seen first hand what is needed when large changes are made. By making the ACTUAL air/fuel the same ratio that the computer is programmed to expect to see, we don't have to worry about the need for a re-tune. For those who are using this system and you want to do a re-flash, Diablo may program the Predator with an option to specify the use of our system to make it easier for the end user (to ensure that the programming doesn't alter the air/fuel ratio too much). They have some test vehicles that they want to use our system on, and I am trying to get them production parts as soon as possible. We appreciate the interest in this product, and I am sure that once people get to try it first hand, it will become very popular.
This package can not be directly compared to any other system, as the inlet pipe alone added 6 rear wheel HP over the stock inlet plumbing. Although our heat shield was not available at the time of this test, a mold is currently being made, and we will update our website with photos and more information about the completed system when it becomes available.

Thanks for the info.
Another question. Since it seems that the HC filter is required for emiisions inspection (for those that have to get it done). How will adding this intake effect us? I assume by the pictures, the filter will not fit in the intake pipe. Should we switch back to stock to get an emissions inspection?

I think I just found my intake system. 15-20 ponies and no need for a chip re-flash...
Sweet.
Lee, be sure to drop back in the forum in Jan and let us know when they're ready to order...

I like everything here but the price. He seems to be trying to recover his mold and setup cost too soon. $250.00 would be a fair price. That comes in at 16.66 per HP gain. The $300+ price still beats the exhaust HP gain claimed. On a score of one to ten on looks this system scores a nine in my book for sure.

Ill wait till someone from this forum installs one and comes up with similar results. Not that I don't trust them, but I've seen alot of promised numbers on other items which have fallen short of their original numbers.
A+ on the look , very clean.

This is a great looking installation, but I have a question. Were your Dyno tests done with the hood open or closed? It strikes me that the Aluminum would store and transfer more heat to the intake charge than the rubber would. Here in Arizona, underhood temps are a major concern.
Nice Job!

Wow, that is awesome!
Two questions:
1. Stock warranty problems? Comments?
2. How hard would it be to swap the factory airbox back in for service if it was a problem?
Wonder what the gains would be if you added a cat-back exhaust?

Not sure how or why it would effect warranty since it is just the air intake. As far as swapping it back it only takes a few minutes to install so changing back and forth would be easy.

i think it may be a benifit on the part of the c&L design that the car doesn't need to be retuned after installing the intake. like they said, since the MAF is the same size you don't need to adjust the computer (which does void the warranty). although after talking with swingle007 and 2005RedGT at their dyno tune on saturday, it seemed like the computer automatically picked up the changes to the MAF from their MMR intakes.

I don't get it.
I saw a 17+hp gain via an SCT tune and removal of the HC Trap.
Now, our tunes may not be the same. BUT, my guess is that a tune that massages A/F ratios is good for 12hp at 87 octane, based on my SCT tune dyno runs. And my HC trap was good for 5-7hp across the board, and the differences were additive to about 18hp difference between factory stock and removal of HC trap plus tune.
I'm not convinced that this cool looking aluminum intake tube actually buys you anything. And it is sure to weigh more. But it does look cool.

My bad, the C&L didn't require a flash.
Well, that looks like an additional 10hp over HC trap removal alone.
