If you are worried about off-boost power, just adjust your ALDA. |

OH NO! Don't go there - FI will be on you like white on rice! JUST KIDDING! Seriously, off boost power isn't the issue so much as responsiveness - at least not for me. But then I'm less concerned with getting more power than I am with optimizing efficiency...

I don't know if you could noticeably decrease the turbo lag or not, but I suspect the turbo lag has more to do with the inertia of the turbo than the design of the inlet plumbing. I've pretty much decided that it is what it is, and I just patiently wait for the turbo to come in at 2K rpm.

I also found a nice series of articles on reducing intake losses. This guy reduced his loss by about 1/2 a psi. http://autospeed.com/cms/article.html?&A=0629

What filter setup was this measurement done on? I tried to read that article, but sentences such as " probably don't have to tell you what a boost gauge is - but I will anyway cos unless you understand ..." and "Positive boost makes cars go hard" turned me off.

The article really has some useful information. Try to force your self to read through the rest of it and remember that its written in a way for rice boys to understand it It gets much better in Part 3 of it. http://autospeed.com/cms/article.html?&A=0646

It is written in a style meant to appeal to, and be understood by, GenX ricers, BUT I believe the principles and tech are solid. I wish I had his differential Manometer to measure the pressure differential between the throat of the stock airbox and the inlet of the turbo. I think the pressure differential across those two u-turns would be a real eye opener...

As I suspected, I saw the u-turn with the stock air box get up to 137* when stuck in heavy (stop and go) traffic (for about 15 minutes). After 12 miles on the freeway the temp in the u-turn only got down to 103 (ambient temp was 96). This was the extreme condition, but the rest were comparable to the level of traffic I was stuck in. It's kind of funny though, as long as you keep moving, the temp stays the same, you actually have to be stuck in traffic for about 10 minutes for the heat to build, then it doesn't want to go away. After this, I decided to make an el-cheapo intake with some stuff from Autozone (cost about $20). I had to use a cotton filter, but I truly believe that I get better filtration than the unsealed, un-fitting u-turn that was on there stock. Since then, I don't see the motor being drained from being stuck in traffic and getting REALLY hot air into the turbo. Since I put it on, I can't say that I have found any real performance gains, but I think the turbo spools up a bit sooner. In the end, I believe it's worth the effort to change to a warm air intake, but only if you spend time in traffic. If you mostly drive on the freeway, I would stick with the stock setup. Honestly, I would like to see an IC that doesn't need much custom fabricating, but I'm not holding my breath. *note, I don't have pyrometer yet, but it would be interesting to see what that shows in the same process.
