Alright man, I will leave your thread alone.



If any of you have questions on the vmount, you can just email me at rotaryextreme@aol.com or you can post on the forum under the 3rd gen section.



BTW, if you are worry about pressure drop, I have the intercooler flow map that shows pressure drop diagram and efficiency. With this core, the pressure drop on a 13B will be less than 0.5 psi. This thing is recommended for a 7.6-8.5L engine. haha

Yeah, I don't think that I'll have to worry about outflowing Chuck's Monster V-mount setup!! That is good news!



Sean, will you be able to supply the IC pipes for the GT40R kit as well?? Or at least recommend a good place to pick up ones that I will need?



Zach

 

I dunno, Zach. Basic rule of thumb is 1.92 CFM per a RWHP. I would like to PLAN on 600, so its close to 1200 CFM. That is ~ what the IC core is rated as. I like more margin.

Tony:



CFM does not indicate how much air is going into the motor. You have to account for the air density.



A engine's CFM rating is fixed but the higher boost you run, the more power you are going to make because the air density is higher at higher boost.



Beside that, the new core is rated at 1400 CFM, not 1200 CFM.

You're preaching the the choir, Chuck. Air Density is THE thing I am worried about.



We all have benchmarks, gut-checks, reference points, sayings, that we use. Mine is 1.92cfm per a RWHP. Granted, this goes back to the days of getting small block V-8's into the low double digits, probably before you were born (me thinks). But I use it.



We can take it to the other extreme (Four Gas Law) and calculate it out. The net, is, what are it's dimensions, it's surface area, pressure drop, or better yet, it's graph showing all the pertinent details at once? That would be nice. Like this:

 

Ok, I'm back from the dead now. Near dead anyway, being sick sucks!! So, any updates from Sean or anyone else that may have pertinent info on this subject??



Zach

 

I will add this for you, I am stuck waiting for some clamps so I'm kinda idle right now but they should be here any day.

The dimension of the core is 19.5" (width) x11" (height) x4.5" (thickness)



Flow Rate is 1400 CFM at 15 psi. All those are given by Spearco.



The flowchart is here

Thanks for the info, Chuck!



That the right chart?

 

chuck dont **** around..... of course its the right one
