Envy Charge Pipe Long Term Review (no dyno)

major_kusanagi · 03-09-2010, 01:13 PM

As I've noticed a lot of concerns about the Envy charge pipe, I decided to examine mine over the weekend because I was worried that the pipe may have been damaged. Besides, I've recently received numerous PMs asking for my feedback. I hope this answers some of the questions I've received. All the pics were taken this weekend. That is, they show the pipe used for approx. 5K miles.

Disclaimer: No one or no vendor asked me to do this. I am doings this purely for the members of this forum.

Concern 1: under hard acceleration, the pipe may crack because it does not have a flex section.

I inspected the pipe very carefully for any damage. My visual inspection suggests it's perfectly fine with no cracks or distorted CF weaves. I've driven my car with the pipe installed pretty hard and I assume the pipe has managed the engine's tilting under hard acceleration.

Concern 2: electric tape is inadequate to seal the intake and protect the seal from heat.

The electric tape showed no signs of burns or melts. It seems to do what it's supposed to do quite well.

Concern 3: The plaque rubs on the underside of the hood.

True. It does scratches the underside.

Solution: I partially filed the right side rivet on the plaque.

Overall, I still like the improved throttle response the charge pipe provides. Does it have a couple of design flaws? Yes. Does it compromise my car's overall performance? No. If you want a perfect aftermarket product straight out of the box, this is perhaps not for you. I am not endorsing the pipe, but just giving the forum my .02.

P.S. a couple of teaser shots of my next mod. That's some fine looking welding IMO.

nice write up and review of the product after much use.

I installed mine over the weekend........slightly reluctant to due to some of the concerns on the forum.

But, I was actually quite impressed with the response and power gains (butt dyno) of this piece. I will periodically keep an eye out for any signs of wear due to engine tilt, but it seems that it will be okay.

Most likely we were fiddling with the same product over the weekend.

Thanks. I see that you say the electrical tape is holding up well. You also say that it seems to do its job, but how do you know it is not leaking unfiltered air? Just curious.

major_kusanagi · 03-09-2010, 01:56 PM

I had the same doubt. Well, to be honest with you, I dunno. I did put a bunch of post-its around the pipe and got the engine up to 5K RPM. But it's not a controlled experiment. i.e., I dunno. However, if you actually examine the seal and groove on both ends of the pipe, it is very tight. In fact, the groove itself should seal just as tightly as the stock pipe.

Great review.

Thanks

SpencerM3 · 03-10-2010, 11:28 PM

Good take.

I agree with most of what you said, I've had my charge pipe for about 1K miles, and so far so good.

major_kusanagi · 03-10-2010, 11:40 PM

I have no dyno numbers to back it up, but the improved throttle response is quite noticeable.

SpencerM3 · 03-11-2010, 12:28 AM

Just checked my hood, and it doesn't look like my plaque rubs.

novablackm3 · 03-12-2010, 01:34 AM

hmm im going to check mine tomm if it rubs then i'll just put some electrical tape on the underside

xchosun1x · 03-12-2010, 11:29 AM

for addition review...

yes, mine does SLIGHTLY rub as well. However, the sound is great. I definitely do hear much more suction and throatier tone.

It might just be in my head, but I really did feel power and throttle response gains.

My next plan is going to try out the LTBMW intake mated with this charge pipe...i hope

major_kusanagi · 03-12-2010, 11:38 AM

If you slightly file the rivets, it won't rub the underside any more.

Keep us posted how the charge pipe works with the new intake.

Bluesummer · 03-12-2010, 05:11 PM

now the question is, having known the issues, is technocraft ever gonna release a v2?

major_kusanagi · 03-12-2010, 07:42 PM

I hope they do although I think it's highly unlikely.

The charge pipe is still a GREAT performance mod IMO. All they they have to do is move or remove the damn plaque and add a small flex section.

Will that be a good business decision? Unlikely given the extent of concerns people have expressed so far, which will dampen demand for a V2. And it already is a niche market.
