Nismo280zEd Posted November 21, 2006 Share Posted November 21, 2006 so i saw a setup on TV where a compnay uses two intercoolers to lower there air intake temp instead of a massive huge FM. So i was thinking... would using two ZX intercoolers effectively provide say 50% more cooling..than one.. assuming the stock intercooler is like 40-50% extra so with two... thats an extra 100% for both... anybody agree or disagree?

Guest Mike Posted November 21, 2006 Share Posted November 21, 2006 I'm thinking of using two IC's on a dual carb set-up (one for each carb). I'm not boosting but will use CO2 to super-chill the air coming through the IC's. In addition, I'll use alcohol injection to further enhance cooling (only during N2O injection). I expect total cooling at WOT to be about 40-60 degrees!! Quote Link to comment Share on other sites More sharing options...

Guest Mike Posted November 23, 2006 Share Posted November 23, 2006 I've decided against the methanol injection because I've opted for a ZEX dual plate N2O system and the alcohol will dissolve the aluminum plates. The N2O will have a ton of cooling anyway... and I'll still use the dual intercoolers with cryo:wink: Quote Link to comment Share on other sites More sharing options...
rztmartini Posted November 23, 2006 Share Posted November 23, 2006 the new audi's have a dual intercooler setup...so it cant be that bad of an idea! Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted November 23, 2006 Share Posted November 23, 2006 What do you guys think about the idea of using an A/C compressor to chill intercooler(s). It's been done and, if one has an A/C anyway, I think it's worth the work. Think about it... no more refilling CO2 or N2O chiller bottles because it's an enclosed system. There's a thread discussing it now here on hybridz. Quote Link to comment Share on other sites More sharing options...
rztmartini Posted November 23, 2006 Share Posted November 23, 2006 i just posted on that thread lol. Janspeed had a setup on a Jaguar that used the Freon. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted November 23, 2006 Share Posted November 23, 2006 I'd like to know more about the A/C chilled intercooler(s). Do you suppose that's a custom intercooler or does someone manufacture these? Quote Link to comment Share on other sites More sharing options...

Guest Mike Posted November 23, 2006 Share Posted November 23, 2006 Yes... but are they SELLING this system as a turn-key solution? Quote Link to comment Share on other sites More sharing options...
Guest magnadyne Posted November 28, 2006 Share Posted November 28, 2006 I would be curious to know the difference between the power lost due to turning the A/C compressor and the power gained by chilling the intercooler. Personally, I don't think you are going to see that big of an advantage. (I could be wrong) The 2 intercooler thing won't give you any advantage over a single one of the same thickness and surface area of the 2 combined. Unless there is some sort of obstruction that will keep you from using one. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted November 28, 2006 Share Posted November 28, 2006 MAGNADYNE... A/C power loss vs chilled I/C power gain... True but, if one has an A/C anyway, why not put it to a second good use? The compressor can be turned off at the moment of acceleration. No advantage to dual I/Cs... True but I have dual quads. Quote Link to comment Share on other sites More sharing options...
savageskaterkid Posted November 29, 2006 Share Posted November 29, 2006 don't quote me, but i've been told ford uses the A/c to chill the intake charge on the SVT lightning, but it only works for a few seconds, just to give you that extra kick.

rztmartini Posted November 29, 2006 Share Posted November 29, 2006 this might be a form of dual-intercooling...the air charge passes through the core twice? maybe a stretch. ill tell yall how it works out. Quote Link to comment Share on other sites More sharing options...
dapiper Posted December 4, 2006 Share Posted December 4, 2006 Running cores in series will double the press drop and decrease delta T driving force on second core resulting in less heat transfer although same area. Of the three modes of heat transfer, conduction, convection and radiation, convection is main contributor for intercooling with the air to air films both in and outside the core the major resistances. These can be reduced by increasing flow speed up to a point and increasing temp difference. Increasing air velocity beyond so called turbulent flow or point of diminishing return will only serve to increase press drop. Increasing temp difference will increase heat transfer proportional to the log mean delta T temp diff. These are the physics. Each application is unique, however and depending on air flow and turbo efficiency and where your engine falls on compressor map which affects I/C inlet temp. Also ambient air temp will determine point of diminishing returns. A smaller I/C may prove more beneficial for lower boost on smaller motor. A larger I/C may be better for top end high boost where the inlet temp is greater and the flow velocity increases to raise the Reynolds number to turbulent thereby reducing film coeff resistance. The larger I/C may be inefficient at low boost, however where delta T and flow velocity are lower through the larger flow area. Quote Link to comment Share on other sites More sharing options...
