Just say a video on YouTube where a performance place is going to make (prototype) a normal sized electric supercharger and plans on making big hp from it, should be interesting! He didn’t give any details but th turbo/ supercharger looked like a good size, I’ll have to rewatch the video.
The torqamp electric supercharger used a 48 volt lithium battery which powered the 80,000 rpm electric motor and the lithium battery was recharged by the cars alternator. GTO George Last edited by GTOGEORGE; 12-07-2019 at 12:53 AM. |

yeap
Convinced you can make your own for waaay less than $1250, and develop-up the depresion to > 3 psi. I got several Toyota "GT28" turbo compressor shells for $30 each on ebay. Impellers from various (ebay, etc) and ran evals, calcs on excel. CFM calcs are humbling so a fella has to be clever. Motors by catalog engineering the Specs for 90A-120A with > 3000 KV (not easy but they exist). So, i bought pairs of 2 design type motors, nailed it the 1st time and bettered-it the 2nd time. NeuMotors is best but start with 5mm shafted Chine junk. I have Commercial-Professional 300 AMP ESCs, and a $8 hobo PWM controller (is good). The Manometer & "Cal'd orifice flow Plate" are key to incremental improvements. A fun optimization. Once yo have goodness, replace the cal-orifice plate with an un-cal'd venturi for relative improvements. I ended up with a 2-Stage that gets to 6 PSI for 3 HP (electrical). Should go into Biz huh. Each stage draws 3psi at 2.7 HP alone, but the 2-stage can be tuned so one helps reduce the other's shaft TQ (current goes down) RPM meter is nice, but ESC playback is nicer: RPM V, Amps, Thermal. Go eat! (Since development time is money, i ought make these for PY folks...instead of $2500!) I think the hardest part is the air MGMT piping Boost to carb Hat. The glossy croud wants $350 for a cast hat. I say no way Use a factory Air Filter case of your liking and plumb a 2"-3" round to Snorkel adaptation and look good the way you like. Single stage boost is meh. dual boost is being dumb (2x meh) 2-Stage boost is an eye opener. Last edited by Half-Inch Stud; 12-07-2019 at 10:06 AM. |

6 psi of Boost is the amount Ford made on the 1978 Ford Mustang 4 cylinder and it was a dog.

What’s really interesting that some people are over looking is the electric supercharger DOUBLED the hp making only 8 lbs of boost no a small 120 cubed 4 cylinder.....that’s doubled, a lot of racers wish they could double their hp with a 30 min bolt (screw) on!! I ran 9.49’s a looooong time ago with only 3 lbs of boost and last year I ran 8.30’s on 7 lbs of boost! It’s not how much boost you run it’s what you do with the boost you are making!!

Some people Stan have never heard of the Term "Cost/benefit Ratio".
I see no benefit to buying a $5,000 set of two Electric Superchargers to gain 100 HP over the stock 100 hp engine when for the same $5,000 you could buy one of Art Whipple's Screw Superchargers and make 1200 horsepower on an engine. Whipple's higher end superchargers are around 5K and will make 30 psi of boost pressure vs say 14 psi on a 8-71 roots supercharger. It has to do with PRESSURE RATIOS and Compressor Efficiency. Roots is poor on both of those just like the electric units discussed. The Leaf blowers being an exception due to their design. Just like a Whipple vs a Roots. At one time they outlawed the Kobeco screw superchargers as being unfair vs the 14-71 roots stuff. Tom V. In the late 1960s, my favorite "Know Nothing" comment from the Pontiac Guys was My Pontiac Engine is better than the Chevy 427 Vette engine because "It has 1 more cubic inch of displacement".

LMAO got ya
Double the HP with 8 psi of boost. General you need a Pressure of about 2:1 to double HP. So for that to happen with 8 psi of boost you would need to be at a altitude of almost 15900 feet. Stan

I'm pretty ignorant about turbos but wouldn't this also cause a carb situation with our traditional Pontiacs? Or are we assuming an FI upgrade? Blowthru vs Drawthru if a carb is used? Seems like the conversation is saying just bolt on a hair dryer and get cool gains?

You need to have the correct Fuel/Air mixture getting to the engine combustion chambers
and the Air Device (Turbo, Supercharger, Leaf Blower, Electric Supercharger is only half of the equation. Videos always make it a lot easier vs the actual development time to get it right and also typically only highlight the good good features and none of the weaknesses. They never do a video where they say your part is a POS. Tom V.

1) Videos can be anything they want to be. Working on stuff as a JOB is different.
Some don't seem to understand the difference. You can criticize something if you have experience on the product and have actually run testing and use that info in your posts. In your case you are just assuming a lot of stuff based on watching a 30 minute video. Kind of like the Turqstorm deal where where the video was showing 25 lbs of minute mass flow (250 hp) and you were posting 500 hp type bullchit. 2) Get out of retirement, apply for a job with Torqstorm, tell them you have no experience with ANY centrifugal boosting device, tell them you run 7.98 with a Roots blower and see if you get a call back.

I dunno. Have not installed the 2-stage due to moving home, etc. Will take time to figure/get a hat on the 1050.
Car runs 12.2-12.0 as-is @3850 Lb. I suppose if it would run 11.0 on the hobo-boost that equal to 1000 Lb weight reduction for same HP NA. I guess that would be +100 hp huh.

Bill Klausing's 63 Wagon ran 12.06 with a basic NA tri-carb system at 4300 pounds with a very mild 455 engine. I would hope HIS could run deep in the 11s 450 lbs lighter than Bill's deal NA. Forget about the Electric Boost system. Bill had hundreds of passes on that car with that low 12 second et. 450 lbs lighter would be the difference (as well as tuning) not the "HOBO" boost system. FACTS not BS or assumptions.
