Converting lbs per minute to CFM ?

Hi team , I’m doing some research on intercoolers and the CFM they are rated at .. I’m currently working on a project, 2JZ swapped Mk3 Supra , targeting around 1200 HP to the crank .. as it’s understood that it takes about 10lb per minute air flow per 100HP .. is there a way to convert lbs per minute to CFM to compare intercooler cores that have a CFM rating ? .. I’m trying to make an educated decision on selecting a core that’s up to the task that’s not too restrictive so I can keep a happy pressure differential .. thoughts ? Ideas ? Is there a rule of thumb when it comes to CFM for making power numbers ? I’m aware of the mountain of variables in making power such as air density , different fuels and boost levels etc etc .. I’d like to keep this narrowed down to pressure differential and flow specifically… all input is encouraged and appreciated !

What I learnt about intercoolers is that they don't work exactly as they are supposed to on paper. That's the case when the bigger the better) For instance, I'm using 120 mm thick cooler that allows me to keep intake charge temperature very low for my 700+ hp. Before that I tried 75 and 100 mm thick coolers that were supposed to give me best result on paper but didn't...

As for conversion it's CFM (under normal conditions) x 0.069 = LBS

Air temperature and pressure will also be factors that might need to be tken into account - the "normal" Shota mentioned may be 32f and 14.7 PSIG (gauge, which is absolute), or something quite different, and that can change things significantly.

Thanks guys .. I did the conversion math Shota posted .. I came up with a number in the 1200’s tho .. I’m assuming I move the decimal and that would equate to 120 ish lbs per minute .. or am I not doing the math right ?

I missed one 0 in the formula ( already corrected). It has to be 120 lbs ( assuming 10 lbs per minute for every 100 hp) devided by 0.069 equals 1800 CFM approximately...

Here is good page that should help you

I believe you need something like that

Thankyou Shota , this makes perfect math and is exactly what I’m looking for .. thanks for the link , it also has some good information that will help me size systems in the future .. your input has been very helpful !
