Folks,

We're happy to announce our 4-Pass intercooler for those running high boost, high temperatures.

Our 4-Pass intercooler is JBPs gift to those who want to retain stock look, with the best cooling possible for high boost, high temperature builds. We've employed 4 specialty laminova tubes, internal passageway mods and engineering know-how to develop our 4-Pass Intercooler.

The nice this about this upgrade is that it is the stock unit revamped. Stock appearance, with double the flow, and close to triple the cooling effect with a 4-pass intercooler. There is no need to upgrade the aftercooler or any other part of the supercharger cooling system once this is in place.

Pricing for the 4-Pass intercooler will be approximately $429CDN. and will include the following:

- 4 Specialty Laminova Tubes
- Replacement High Flow/Volume Pump
- Replacement Stainless Braided Steel Coolant Lines
- Modified Coolant Outlet Ports
- Double Inlet Ports
- Instructions for installation

Customers ship us their stock Intercooler, we ship back the 4-Pass Intercooler, ready to install.

 

so this is like the dual pass gm stage 3 uses, only more effecient?

 

No, the Stage 3 is a 2-Pass, this is a 4-Pass.

 

pictures???

 

Pics?... Hmm, I think you'll be disappointed since it looks exactly like the stock unit.

edit: with an extra 1" Russel fitting sticking out of it.

 

Pictures and numbers!

 

please define '4 pass'

does it go thorugh all 4 at once? because that is a single pass

if it goes through all in a serial manner, that is a 4 pass, how it is stock. the fluid makes 4 passes through the manifold.

 

i'm more intersted in the high flow pump and steel lines you speek of.

 

So is that how people define the passes? I haven't heard anything definite yet, but everyone has been throwing around something different. Using your definition, I think what they are selling would be considered a 2 pass.

 

Actually, you have it backwards:

Stock SINGLE Pass, Single Inlet, Serial run.

JBP:

Stock QUAD Pass, Double Inlet, Double Parallel run.

 

Also, I am a bit leary of a higher flow pump. If flow increases, more than liekly the pressure in the system will increase (the manifold might flow more now, but what about the stock HE? anything over 5psi, and the system leaks

EDIT:

Ok, well, the termionolgy for a 'pass' is actaully very debatable, but that is niether here nor there. the fact is you are running all 4 cores in parallele.

are there any logs to show improved IAT2s? This will increase flow, but decrease the time the fluid spends in the manifold, letting it 'absorb' less heat.

Just curious on how effective it is.

 

Hence the new provided lines.

 

Maybe putting up a diagram would be very helpful. This is all getting very confusing, everyone is calling the passes something different. If you guys have just added one exit fitting, then everyone is referring to that as a dual pass.

 

What are the IAT 2 temps?

 

When I have some time, I'll explain with a diagram so everyone has a clear idea as to what a 4-pass is.

 

I'm excited for this!!!

any price idea?

 

sorry, missed that part. pretty impressive package. Still raises the question about flow vs. time spent absorbing heat.

EIther way, I am sure it works very well. I would love to see some data logs!!!

 

listening....
if you say that an aftermarket heat exchanger isnt needed with this unit, im in 100%

 

Sorry you have it backwards. Stock is 4 pass. Between the inlet and the outlet the coolant passes through 4 seperate laminova cores and has to go into a chamber to reverse its direction each time.

so two inlets (on what used to be the stock inlet and outlet) and one outlet ... in the middle of course... than that would be the dual pass setup... unless you got something else going on here... clue me in... I just did a dual pass on my car.. and saw a decent decrease in my iat2... is your setup different/more efficient... got any logs to show difference... not being a P.I.T.A. ... but I"m a glutton for info.

 

Did you ever rearrange your cores?

 

He gave the price on the original post.

 

Didn't get a chance this weekend... and next weekend looks like I gotta swap a tranny on one car and a motor on another... so... hopefully I'll get a new intake gasket in the process and get my car finished one of these days... still haven't put my rear tranny mount back in... sitting in my trunk for weeks now.

 

You will not see 5 PSI from any automotive intercooler pump in a working system. It's mostly thermal expansion that causes the pressure rise.

If you assume a perfect pump the time for the coolant to go all the way through 4 cores in series is the same as 4 cores in parallel.

Frankly I'd be more worried about balancing the coolant flow through 4 cores in parallel.

Holy **** I'm really confused right now. I need a diagram to follow this one.
