General Supercharger Thread

FYI, I just recieved my core deposit refund from Cruisers...legit!

 

I'ma leaf dis hear...

I agree that in our configuration, it probably makes little difference. Getting rid of the hard turns will probably help more. Those -16 pumps are expensive, I was pricing out an upgrade and the pumps and lines/fittings would run around $1300 and welding fittings to replace the reservoir inlet/outlet.

 

Yeah that’s something I’d like to do one day. Would be cool for before/after testing when installing spacers and thermal blanket.

 

More information on heat transfer related to liquid movement, this time from outside of the automotive performance industry. It gives me the brain pain...but if I'm interpreting it correctly, higher liquid velocity and more surface area that the liquid comes into contact with, results in a higher transfer of heat from the liquid to the contact surface. So in our world, higher pump speed + larger heat exchanger + higher fan speed + reducing restrictions (such as bends or small hoses) = colder IATs.

Most articles I've read refer to Newton's Law of Cooling as reference.

Mathmatically, I am in the lower percentile, luckily for me, I rarely need to do math in my head (oddly, I'm good with $ math) lol

That said, it seems common sense, if you increase flow, amount of coolant & the size of the intercooler, temps will drop. Hence I have a big intercooler, the ZZP pump & a ginormous reservoir.

My IATs are pretty low.

 

On your Sequoia maybe, the IATs on your BMW still scare me

 

I am at the conclusion the e36 was designed to have high IATs, stock cars are reporting over 140 in sub 80 degree temps. Seeing 160 in 100 degree temps SC doesn't seem that bad.

Currently it's running great, although it is too damn hot to drive a convertible in the sun on 100 degree days. It's "cool" today & "only" 99 right now.

 

Oh man. I'd have a hard time invthe 90's. I like the rain and high 60's low 70's.

 

I just completed my move from Dallas to Denver last weekend and it's like early spring all over again. Feels great! High of 63 today

 

Reason I went with the bigger intercooler and zzpump. Would of been nice to have a before and after IAT's for all the changes made.

 

Congrats on the move back. Glad it went well and worked out.

 

Got any pictures of a setup like this? The magnuson intercooler takes up a lot of the space in the front since it is centered, which is why I was looking at the GCS setup.

Here you go good sir, all the details. This was for a guy who installed a blower on too.

 

Aren’t you reading IATS at the MAF pre supercharger? I don’t think more flow can be bad in an intercooler circuit, which actually is a real concern in other applications like commercial chillers. I’d just argue that a pump that is rated higher by quoting its GPM capability pumping into a bucket vs against the head pressure of a restrictive intercooler circuit isn’t actually providing more flow as shown in that testing shared. A bigger intercooler is definitely effective for increased heat transfer. A larger reservoir is beneficial since it will take longer to heat up the greater volume under boost. A pump that flows 10% more into a bucket, but likely 1% more when pumping through the intercooler circuit. Meh. I’d probably lean toward the OEM selected, well tested Bosch known for its longevity and service life.

One thing that would actually likely boost the flow big time despite using the same 3/4” lines and intercooler would be installing 2 pumps in parallel. The flow is most limited by the Total dynamic head pressure (discharge pressure minus suction pressure) it is able to produce against the restrictive system. With 2 pumps in parallel they share the work load against the pressure. 2 parallel pumps would reduce system head against each pump, and the pumps are able to operate at a more efficient spot on their pump curve. It would probably allow both pumps to move 4GPM before hitting a wall on their pump curve instead of just one, multiplied by 2 pumps could result in a true 7-8 GPM intercooler system on 3/4” lines. 2 Bosch pumps in parallel would probably only draw 6 amps too.

 

I hate it when it's over 80, moved here for 6 months in 2006. Best laid plans & all that.

I am reading IATs from the OBD so it's wherever that reads. I got my kit used, missing the IC & pump so had to buy them anyway & got "upgraded"

 

Same. Was having a discussion about replacing our 200 and 185 ton chillers with two 300 ton chillers and the need to add an additional pump to our system to support them. Gotta get flow just right for the amount of heat exchange available keeping delta T right about 10f

 

You could just oversize the pump a bit and use a VFD with speed modulation based off of differential pressure. You’ll save on energy too, and it will modulate to meet the demand of the flow of the system as control valves open and close.

The concern in HVAC applications for slowing down the flow to achieve a specific delta T to satisfy the needs of a refrigeration circuit doesn’t really apply in the scenario of an intercooler pump though. In an intercooler there is no such thing as too much flow. There may be a smaller Delta T on the entering/leaving water with more GPM, but there will ultimately still be more heat transfer that will cool the whole circuit down faster.
BTUH = GPM X 500 X Delta T.

More GPM does mean a lower Delta T, but doesn’t necessarily mean lower BTU removal.

 

Just about every motor we have is VFD driven. Even our air compressors are. In the summer, we can get to the point where we need in excess of 600 tons for cooling our plant. Usually we run 2 pumps until the 4th chiller fires, then we run all 3. Having the larger chillers, I want at least one pump for each chiller and be able to have redundant pumps for maintenance and failures. We’re running them off of dP from the furthest point away in our plant. You should see this other pump skid we installed in the last project. Grundfos stack pump skid with the VFD’s attached to the motors. Had to increase the HE size as well to the heat load demand for the lasers. Now the HE is running at SP at about 70% vs what it was before at 100% and would get up to 3c above SP.

 

You can also squeeze in a long 19 row in there similar to the oem location.

 

I like this idea. Do it…

 

Very happy with the Maggie 2650. About 400 miles in so far. Loving it! Not sure how I ran 37’s without it! It’s my daily driver. If your on the fence do it!

 

Once you own a v8 truck with boost, you'll never not own one again! Congratulations!

 

Just wait til you get the smaller pulley, bigger injectors, better custom tune, and all the other peer pressure items from the forums. That blower is capable of so much more than the kit config and you’ll live every second of it

 

How could anyone.. NOT Love a boosted V8!!!

 

@bmw345 congrats! My suggestion is get yourself a performance valve body. From there enjoy driving it and adding the power mods with less concern for the transmission. You can avoid premature wear on it if you do it from the start. I wish it was my first mod, aside from custom tuning.

 

vb now or built trans later

 

Agreed, high on the recommend list now. Had another guy I've been helping have his trans go out a few days ago, and he had installed a valve body in January trying to save it. Likewise a guy a few blocks down, same exact story, valve body to save trans when it started slipping and it prolonged it a few months then totally went out.

 

Dang. VB may just be temporary anyway. Might as well get a trans from one of the reputable companies that provide them for our trucks for peace of mind.
