Truck should freaking roll out!

Lysons · Apr 30, 2014

So why are you going with 3 "same" sized turbos?
Someone explain this to me.

JDub · Apr 30, 2014

Atmospheres are the same size, s300's with 67.7mm compressor with 80/73mm turbine wheels. The high pressure is bigger, its an s400 with 67.7mm compressor and 83/74mm turbine.

I believe kind has a setup like that but I don't understand the reasoning either

Spools faster than a conventional large atmospheric turbo

Lysons · May 1, 2014

How much air would these three turbos flow?
Equal to an S480? More air? Less air?

So are we talking like S510 area then?
or is that overkill?

S300 + S300 + S400 = S1000 duh....

JDub · May 1, 2014

In a compound setup, you only move as much as your atmosphere moves, even in triples which is still a basic compound system.

An S480 moves around 120lbs/min. Those S367/7 atmos move around 90-92lbs/min each, so the atmosphere in this case will be around 180lbs-min. An S510 is just over 160lbs-min.

You watch your filthy whorish mouth. LoL

If two 67 fmw can flow 94 lbs/min each. Then it's probably close to what a 105mm flows. Depending on how efficient their plumbing is and what not.

Time to wake this up, anything new boys?

At this point we are waiting for a few things to come back from the coaters. Once they are back the mad rush to get her done will begin. We have a few parts left up our sleves to throw on to her also.
