So did you find any documentation supporting raising the intercooler off the floor on a twin screw application?

 

There's some info floating around for the Maggie's and LSAs.

It was significant if I remember correctly. I believe Richard had tested his put some before and after IAT numbers up.

 

Yeah stuff about raising it off the floor, floor design, discharge point (front, rear, centered) and distribution...FI and Blow Thru

 

Yea there is a lot to be said about it. Its not so much about plenum volume as it is about creating an efficient flow path for the air and using as much area of the intercooler as possible.

 

I didn't ask if they would but they only have 1/2", 1" , 1.5", 2" listed


The stock floor has a very slight curve to it but I have ideas to make a better flow path like a tented roof design

 

I think I would shy from a sharp edge... again the clearance below the intercooler is what it is for a specific reason. It helps to use the entire intercooler. With more of a hump you will force the intercooler to use its edges more and in turn help direct airflow even better. thats My opinion anyway...

Look at the LSA lid. Obviously guys have great luck with those.

 

IMO with this Whipple the little bit of clearance below the intercooler is for packaging reasons. They would've made more clearance and used a large core like they do on mustangs if they had more room under stock hoods. But yes I agree a rounded center with it sloping towards the ports is better than a sharp roof.

 

Oh if they could have fit the large core they would without a doubt. But I don't think the clearance is a mistake.

 

Look at what is now standard on all COMP LS Camshafts:

COMP Cams Micro Surface Enhancement - CPG Nation

They aren't the first for this as Crane Cams (Mikronite) has offered this similar treatment for quite some time and the process for out sourcing has been around from a very long time "isotropic / supermicro / REM etc polishing"


Gen5 Nice intercooler that makes the air flows through it twice and a splitter in the upper plenum to divert/channel the air. Basically the entire rotor casing/housing also gets cooled by the chilled air which is a plus.

And a pic of the Gen 3 design

 

Also noteworthy is that it's now a 3/4 lobe rotor design as opposed to 3/5. So at the 18k blower rpm limit you'll now have the second rotor spinning 24k rather than 30k. I'd imagine it will allow for higher RPM limits on these rotor packs.

Lookin a lot more like a TVS rotor design if I do say so myself. Obviously they spin in different directions... but I wonder how much more efficient they are.
