The conduit that feeds a turbocharger, is extremely restrictive. Experimentally, determined that 4 psi is lost in this piece of plumbing, that connects the ambient supply to the compressor.
My question is, what would the temperature change be? Assume ambient of 100 F, at sea level. Is there...
Thanks, I finally looked it up. I guess as an engineer, I fall into the classic "no common sense" stereotype.
To address your statement, I don't think it is the case. I just determined that the intake has a 5 psi total pressure drop, and that the hot side plumbing is 2-4 psi, depending on...
I am taking a Zytel part, and modifying it for prototyping. It will involve build up and maching of part of the piece, similar to using fiberglass and resin. I need something that will bond to the nylon.
Can I get some ideas on what materials/process to use?

A big part of the objective, is to take an inefficient charger operating off the right side, and real it in.
Inasmuch, there are much more benefits than just cooling charge. Lower drive pressure=lower egt, higher comp efficiency=more MAF...etc.
I realize that water has a small displacement...

is it possible you have damaged the turbine?
If this problem showed up gradually over time, perhaps you have gradually rounded over your turbine blades.
Yes, in some vehicles, oil is every bit the coolant that water is, naturally VW is a good place to find an example. I did an article recently on this as it applies to the duramax motor.

Interesting thread. This is such a science (and I agree, with so many variables, there is no linearity) that even the automakers struggle.
Mookinator, if you wanted to consider "all things equal", then you would take your 10 degrees, convert it into time (us) before peak cylinder pressure, and...
I can see where you would think that, but no, a single charger. With such a lousy hot air intake that up to 240 F has been logged in the intake.
The reality is that a simple CAI will be the cure. But I am going a step beyond that.
very useful, thanks. I would not have thought of symetry. Id there anything I should consider in the aero shape of the fins?

Presently have a turbo that is run off the right side of the map, NE side of the map to be precise. It runs into very low efficiency numbers, and the boatload of heat it is crating is problemeatic. GT40 compressor, with inlet temps of 220F, higher elevations, trying to push 50 lb/min, at 25-29...
It is a tough drive combo. 100 HP is mot too bad on it as long as it is not in 5th.
The effect on combustion delay and burn rate is my main concern. I don't want to cause MEP spikes at TDC. Some kind of timing retard would be prescribed. But I can only guess what that would be.
