Project Thread 3.3ltr whipple into Ls400

The 1UZFE EGR Delete Kit is available for sale here.
Cross section area of the slot is fine. 18mm (0.71") by 300mm (11.8") (guessing on slot length since total length of the cooler is stated at 410mm) is 54 sq/cm (8.38 sq/in) which is more than the cross section area of a 3.25" exhaust tube and there are 4 of them in this design. The shape of the slot(s) also contribute(s) to the distribution equalization. The edge shape may not be ideal since it is fairly sharp but everything is a compromise.
The design of the cores looks robust enough to try something like using a CO2 bottle and doing an expansion cooling settup instead of water through the cores for short contests such as drag racing. Maybe water and CO2.
Still compromised compared to a nice open plenum is my point. As i said, waiting to be convinced and currently i'm not by some paper specs. Real world results i have seen have been mixed and the independent result was poor?
The theory is good but useful real world only if the application is also good. Maybe they are sensitive to design parameters or fabrication tolerances?
Some healthy sceptism is not a bad thing. I have seen combo's that were supposed to work... not... and I have seen things that should not work... work!
That said plenum area is only important after cooling and that area can actually extend into the cores to some degree. Less expansion and re-compression means lower pumping losses.
The total flow area of this proposed IC core is 54 sq/cm x 4 x 66% = 1425 sq/cm ( 22 sq/in) (corrected my previous posting from 540 to the actual 54 sq/cm). Anyone have any area calculations for a typical tube or bar and plate A/A intercooler core? My guess is the equivilant will be a big core.
Here is a posting that claims the tube style pictured has 3.2sq/in while the bar/plate style has 5.3sq/in. These look to be 5 inch tall sections. This would equate to a bar/plate core more than 20" tall to equal the cross section area of the Laminova design here. A twenty inch tall A/A core is pretty stout.
Of course proof of concept is always needed. My guess/vote is that it will work well.

Where these setups look to fall down to me is not the core, which is very clever, but the slotted housing you use with them? The 15mm slot is not a nice entrance, less than ideal shape and compromised x-sectional area?
I have only seen 2 tests with completely opposite results, so for now i'm waiting to be convinced...especially as it's a fair investment to go down this path.

OH YEAH BABY !!!!!!!! Now your talk'in...... like ...................................WOW .......................
.
man, i like that.... i like it alot..... i can't stop looking at it........
..... . . . . Now that's a real f**k off system.. .. .. . . . . . . . .

Yeah there was more in the tune but even 270-80 rwkw is pretty decent considering how much they take to drive at 16psi?
It definitely needed more WI in the plenum so a good chance for the new owner to tap in an extra nozzle or 2?
Whatever, it was never going to touch the TT setup....just worlds apart i'm afraid.

I reckon you'll be happy with it 
Twinscrew is more efficient so you'll make more hp/psi boost.
If my setup sat under the bonnet line i'd probably have tried to develop it a bit more but i really missed that mid range punch the turbos deliver.
If you do go turbo forget the garretts...those ones anyways. The new Borg Warner turbos are definitely the best bang for buck around, if not the best outright turbo at present. The new light weight wheels and and package design is pretty darn impressive.
The only garretts that would touch them would be the new GTX3076R with the Tial turbine housings?....dammed expensive though.
