I just want to see some logs and see how low it takes the IAT2's.

 

Why won't we see 5psi from out intercooler pump? Some are rated at 5 and some at 3, but the Bosch are rated at 7psi...GM doc 1471156 states under the intercooler system that it is rated at 7psi...

 

And noremorse and pierre are right, stock it is a 4 pass. You stated that it looks stock EXCEPT for 1 addt'l fitting which means it is a 2 pass or dual pass. Two inlets (stock inlet and outlet) and a fitting tapping where the second and third intercooler cores transfer makes it a dual pass and that is the outlet. Or vice versa really with one inlet (new fitting) and stock inlet/outlet as new outlets.

There was a shop that did a build of the LSJ and did a dual pass, then a 3 pass but there weren't noticeable gains for the 3 pass to be worth it.

Reference to page 8 of link: http://manual.lsjowners.com/ecotec300hpbuild4.pdf

On the left is the dual pass, the right is the 3 pass.

 

Because If you ever see 5-7 psi in your system, then you have a major bottleneck/restriction somewhere. If you plug somewhere in the line it may get up to 7psi, but that doesn't mean that is ideally efficient. Thermal expansion may get it up to 7, but that has nothing to do with the pumps rating. That is just the hot air/hot water pushing on the cap wanting to escape. I keep my cap on loose just to not let the thermal pressure build up.

 

The dual pass setup you are talking about is that the C/A H/E? How much did your IAT2 drop? It would be interesting to compare these two setups.

 

He's not dumb, he knows what he is talking about. He has a dual pass just like JBP is marketing, just not released yet by the other company!

 

I think I put a post about it up... but if not... I use it in conjuction with the c/a front mount... and I see during cruising an average IAT2 of 25-30 deg higher than ambient... I"m running a 2.5 pulley and with the meth my peak temps are around 130ish deg and the temp drops pretty much immediatly after a WOT run... maybe 2-5 min of reg driving and its back down to where it started... no more heat soak haha.... but I also have the meth injection which helps substantially. .
I think they'll have my logs posted on the site soon ....
sorry to hijack the thread JBP

 

I'm also curious of what is so special about the laminova cores? Our cores are made by Laminova in the stock intake manifold...

 

this is a confusing thread... cant wait to see the diagram

 

i think this information is a little missleading

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


your really not including any additional intercooler tubes only offering some braided hoses and some fittings and some modifications to an oem system

not saying its not worth 430 $ but i was a little confused when i read it and then read the rest of the responces that were made

 

Well... from my standoint... I do know the end cao (with the inlet/outlet) is pretty damn expensive... over $150 from gm..

 

Yeah...whats the point? We have to send them ours and then they modify it, so that $150 is nothing since they never have to buy one...not like a core swap or anything.

 

AAAH.... I didn't see that part.... but I do know c/a (I know I know) is trying to do it on a core charge basis to keep costs down.... (I know sorry hijacker..)

 

oh yeah and if they use good quality braided line... that **** is damn expensive in the -12an size that we have to use... plus those fittings priced are no joke... trust me on that... I"m using them

 

Are braided lines on an intercooler set up worth it though? Cost vs power efficiency?

 

not really... but they do look good... lol/... but so far mine hasn't gotten hot enough.. or built up enough pressure to do anything to the plain rubber hoses... I actually have some of the stock rubber hose connecting to the resevoir cause I couldn't get the braided line to make the bend...

 

also alittle added protection from road debris and whatnot... I use em and I'd keep em... due to the fact I drive through Queens and Manhattan everday

Do you have a link to the GM document?

Im def interested in a 2 pass system! i just got my cobra heat exchanger so this weill help even more!

 

Quite the number of posts since I last left off.

At any rate, the pricing is very reasonable for what is offered with the system. The replacement pump, lines, fittings are all very expensive as mention by a few members.

There also is a optional surge tank (pending design), that will be available near the end of the year.

We're very excited about this product, we see it as a huge seller.

 

PM me your email address and I'll email it to ya, Wop sent it to me in an email and I have it saved to my desktop so just PM me.

 

What kind of pump is the replacement pump though?

EDIT: Also, what is different about the laminova cores?

 

I am looking very foward to seeing these charts/graphs. This would be one of the first mods I do after Stage II, smaller pulley, intake, exhaust. Should see some nice gains, car should run better. Specailly with a tune.

 

The pump is a centrifugal pump composed of heavy duty components. It is noticably somewhat noticably louder. The pump has more flow with a moderate beneficial increase in pressure. The pump is MANDITORY in order to run with the laminova cores, which have one extra liner to promote quick heat dissipation and a pressure increase because of the 4-pass parallel flow.

 

sounds interesting
