A faster pump is a useless endeavor(period)

The faster the flow the less time in the heat exchanger and the hotter the water will be reentering the laminovas.

You have one of two ways of increasing the cooling effect.

1) add a second core for passing the water through or a larger core. The cooler the water entering the laminovas the cooler they will stay.

2. split the laminovas up and install a second pump and heat exchanger. This will in effect force cooler liquid quicker, actually 2X quicker since the flow will come from two separate sources.

The second one is not impossible to do either. And I have actually seen a pump with one electric motor attached to two pump units end to end.

If you can add a second exchanger then you can add a second pump or manufacture a "piggy back" pump and split the laminovas up.


If you are serious about cooling a supercharger then those are the ways to go and the second has been done and is a far better performer.

 

Cobalt is his daily driver. Car was on gas on the 2.5 for 6 years. 1.5 years ago he went E85 and the couple months ago went on the 2.4. Quick little car and does well againest our TVS car. He's def around 300 whp. Basically we keep an eye on things and know how to care for the car. Its driven hard still, but the so called heat people talk about from the pulley isn't an issue. His h/e system works great. We're not doing back to back to back pulls.

He knew that buying the pump but wanted something that lasts longer then the Bosch. So far it's been great. As for the flow, it's not an issue. He has almost the same temps iat2 as my TVS car. In the winter I'd top out at 130 iat2, his M62 would top at 140 iat2. Still good temps.

 

Why you gotta be the motha ****** fun police?

 

You have any proof that any of that has a positive effect or actually works?

 

How sure are we the the OEM pump is moving coolant at the most efficient speed for the most beneficial cooling though?
GM did not have this pump designed for the cooling system in this car so we are only really left to assume they designed the cooling system for the pump they used. I am not saying you are wrong, it is a great point honestly and one I did not originally think of.

 

Tech info on the stock LSJ intercooler pump | ZZP News

 

I doubt gm designed a pump around our system or the system around a pump

 

Exactly. Especially because the pump we use predates the car it is in.

 

I came across this article when I was searching. It was also written before the pump that I am asking and talking about was available.

 

if you want better iat2 fix why they get high

 

Best I see is 40 over outside air temps cruising.
I have fresh coolant, option B, restrictor installed, FMHE.
Pump is working now (had some debris in it like you said).

The way the car sits on a 2.9 with 60's it couldn't make it down the 1/4 because it will hit boost/timing cut due to heat. Car cuts timing and boost at 165 degree IAT2.

by mid third car (from a dig) the car hits that temp.

 

Jeez man, what kind of fuel? Meth?

 

you still have air in the system or the pump could be starting to **** out even with the option b it took mine a little while to bleed another thing is if you setup the option b like how zzp has said to do its supposed to be better and faster

 

Your temps are way to high. I cruise an average of 10 over ambient and from a 2-4th gear pull max at 130.

Redo your set up

 

Out of curiosity, has anyone used a vacuum bleeder to try to remove all the air? Or is it a general waste of time with the option b?

 

ambient is cool but on your pulls your on a tvs and a large that makes a huge difference pulley that was around I was on a 2.9

it should work how well who knows from what I have read the best place to run your option b line is directly from the top core to the tank as that's where most or all of the air gets trapped in the manifold

 

How does ZZP say?

To what specs?

 

zzp said to drill and tap the manifold at the top core(I have the instructions somewhere)and run the bleed line from there to the tank because most or all the air gets trapped right there in the top lam core

 

Hmmmm.
I did not come across anything saying this. I am interested.

 

Me too and that makes perfect sense

 

ill see if I can find them

 

Sweet.
Thank you.

You may be right about the pump in mine as well; it has been like that a while it seems.

 

where to drill and tap you will need a 90deg 1/8th in npt fitting



lam core orientation for correct airflow around the cores

 

i also think a oil recirculation system would help the bearing as well

 

200 deg oil vs H.E. temp ill take the H.E. setup that steg has they can mod a tvs snout also and another thing to look at is engine op temp
