Banks iDash 1.8 super gauge
« on: January 04, 2019, 07:08:39 AM »
I was just wondering if anyone has looked at the Banks idash 1.8 gauge.  They have some videos on YouTube talking about air density vs boost which is not really that new per say but great info on it.  He uses it to measure the intake restriction on his supercharged mercury marauder.  I'm in the hvac world any as a designer flow is all I work with and I can tell you that density is a largely missed aspect of air measurement.  Anyway just wanted so opinions on this from you all.  Check it put pretty great info at the least

Density and Volume are more important then intake restriction measurement (Boost PSI) which I am sure you know.

So for everyone else... Which is better 500 cfm @ 3 psi or 500 cfm @ 10 psi?

First off, I love multiple choice! :)

Second, this gauge seems pretty cool.

Third, if better = more horsepower, I'll go with 500 cfm @ 10 psi.

It's a trick question.....both theoretically should make the same HP if atmospheric conditions are the same.

However, if the turbo that makes 500 cfm @ 3 psi is turned up to 9 psi.... we can assume it should produce more then 1000 cfm if not more.  That is called turbo efficiency. 

We can quickly go down the rabbit hole about boost psi (remember that it is a measurement of restriction).  More boost usually means more heat, more compressor surge, more back pressure, higher IAT's ect. Sometimes more isn't better, esp if you are operating outside of the compressor map. The small turbos on our SHO's I believe are a bit undersized. However, they do work well in the bottom and mid range great.  I think twin 58 mm turbos would be awesome on these cars.

However, it is widely accepted that more volume (cfm) with less boost pressure is better.

Tricky.....I'd like to change my answer. :)  But wait...isn't more ALWAYS better? ;)

Thinking about this more....HP gain/loss aside, wouldn't the air velocity be higher with the 500@10?  if it's flowing same amount of air at a higher pressure, I assume you'd have to have a more constricted opening, no?

As expected, it is a party line LOL

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

The air velocity is only as good as what it holds, and only then can you say more is better right.  I work alot with hot water systems and when I explain to contractors about velocity and DELTA T ( temp change)  with water flow all i say is that you can move the same amount of heat 2x faster and 1/2 as slow but it is the same amount of heat... but the thing that chances is time.  With these cars the turbo was selected i can only imagine for good low end torque till about 100 mph because most of these SHO will have a wife in the passenger seat and at about 100 you feel the car just leave 3rd gear and really start to pull and that's when she slaps you saying" knock it off".  So bigger turbo is what we on the forum would have loved but ford listened to the wife.

I just copied and pasted the link i was on when looking at it... sorry if that didn't work.
