Go to a Goodguys event if you can. Torquestorm is always there and I usually see several cars there with torquestorm superchargers.

Couple of my buddies have bought kits, but no installs yet. Blower is supposed to make about 9 psi IIRC.

Interesting, and that's with a tiny hydraulic cam. A little more motor and a little more boost could make a fun street combo.

I stopped in to Torque storm last summer in grand rapids Michigan. I had a bunch of questions and they answered all of them gave me a tour and really spent quality time with me. I am almost done with the new motor and when that's done I will be buying one of these as of right now. He also mentioned if you really wanted they can put a different size pulley to increase the boost.
Awesome shop and awesome guys.
Thank you Kiddart

can these be intercooler? I see no reason why not, just wondering if they have done it. Yes.......

Although some manufacturers claim a specific horsepower increase, superchargers actually add horsepower as a percentage gain (percentage of an atmosphere). Assuming an engine with a compression ratio of around 9:1 running pump gas,if a supercharger gives your engine 14.7 psi of boost (another atmosphere) that will essentially double the output of your engine, everything else being equal. After adjusting for thermal and mechanical energy transfer, if an efficient centrifugal supercharger is generating 7.5 psi (approx. 1/2 an atmosphere), you will see around a 35-40% gain in horsepower and torque at your non-supercharged maximum horsepower rpm. If detonation forces you to use an ignition/timing retard system, you will of course see less of a gain because backing off several degrees of timing will greatly reduce an engine's power output. At higher boost levels, the heat generated by compressing air will produce diminishing returns as the boost is increased, although the use of intercooling or racing fuel can avoid this scenario of diminishing returns. Assuming the use of intercooling to run higher boost levels while maintaining reliability, a 100% increase can generally be achieved at around 17 psi on an engine with 9:1 compression running pump gas.
https://www.procharger.com/how-much-horsepower-will-supercharger-add-my-engineI was looking at the Torqstorm kit for 225 /6. That would be fun in an early A! Prices look better than Procharger too.

Way too much of that written by the sales department. " superchargers actually add horsepower as a percentage gain (percentage of an atmosphere)" Except for the power lost in the drive, pumping loss, and heat expansion of the charge. " if a supercharger gives your engine 14.7 psi of boost (another atmosphere) that will essentially double the output of your engine" This never happens.

i'll give you that. While there have been engine builds that have superchargers doubling the output they are a special set of circumstances with well planned high dollar builds. You shouldn't think that by just adding a supercharger you can double the output. An instance like that would be a very specific and expensive combination that would not last long in a higher mileage engine. Best you can, or should hope for, is a more realistic 25% -30% if you expect it to last in real world driving. Yes, factor in parasitic loss and heat and detonation mitigation efforts which will bring that 50% down in a hurry.

in theory doubling the pressure doubles the horsepower,
This was known to conflict with thermodynamic laws 100 years ago.

Yes, I'm not arguing that and did not write the article..I'm just saying that as I read it it was trying to move from the simple and understandable notion that that if you put in twice the air and fuel you'd expect the power to double, to the more accurate and technical representation which is that due to losses etc, you don't actually get that.
Feel free to read it differently, as I said they could have worded it better, it did not come across to me as stating a scientific fact, which is supported by the fact they immediately contradict it....YMMV

It came across as a sales pitch that they misrepresented as science.
At the pressures you're going to see, an Eaton (somewhat better than GMC, worse than Autorotor) may reach 70% efficiency: the gauge shows 10 psi, but the actual change mass is not (10 + 14.7) ÷ 14.7 = +68%, but ((10 × .70) + 14.7) ÷ 14.7 = +48%. Then subtract blower drive loss...

The last 10:71 super charged street hemi motor I built and dyno tested made 924 HP at 7300 RPM with 7.0 Lbs. of boost, we swapped the pulleys to go from 13% under driven to 12% over driven which ended up making 12.0 Lbs. at 6500 RPM and 1027 HP before going into detonation That was not quite doubling the pressure by over driving that 10:71, the manifold inlet temps go up any time you compress air more, hot air expands also so the resistance to the rotors compressing air goes up also robbing power from the motor to drive the super charger I remember one of the NHRA T.V. announcers commenting several years ago that the top fuel blowers take over a 1000 HP to drive them

One thing that makes the math not quite intuitive is the fact that no engine has zero vacuum @ WOT (the usual Holley formula produces 1.5" vacuum), so 5 psi boost is actually a 5.73 psi improvement (compared to NA). Roots etc. which add fuel at the top (not Eaton which is EFI as OEM) also cool the charge as it vaporizes, no effective prediction on density. Even this is complicated: 1. very fine fuel atomization (annular venturis, big mains, big HSAB) cools most, but gas vapor displaces air mass. Also makes bigger explosions if you hang an exhaust valve! 2. large fuel droplets cool less, but subtract much less from air mass How to tell which? Listen to your engine builder, or do A > B.
