    planning for my E-SC powered Nissan Fuga has begun

    Is your assessment based on the exact same equipment, or specifications that he used in the example you are referencing? I've looked into this motor and can't get any definitive specs for it, except to assume the lowest performance ratings I've found are correct which is approximately 25K rpm...

    planning for my E-SC powered Nissan Fuga has begun

    Will this motor be strong enough and of a high enough rpm to accomplish the pressure levels you'll need?

    Supercharger / turbocharger shaft horsepower

    This is a highly diverse and customizable option. Superchargers draw more parasitic power than a turbo because they're always driven by the crank unless the system has a clutch activated pulley. Turbos are considered free hp in error bc they are driven by the exhaust gases after the chemical...

    Supercharger / turbocharger shaft horsepower

    In other words as I've projected, efficiency goes up for the entire system relative to the traditional turbo, more power generated for less input into the system.

    Supercharger / turbocharger shaft horsepower

    The BorgWarner bot calculator lists shaft horsepower for a given boost pressure. I just had a thought regarding this while considering what motor I want to use in my finished assembly. Shouldn't those values be inaccurate for our application? For the traditional turbo the values were derived...

    RX8 Renesis Rotary eSC

    That spec is in Fahrenheit and yes that's about it. That temp drop only condenses the air charge slightly and a number of dyno tests have been conducted to validate that water/meth injection alone doesn't add more power in the absence of increasing the ignition advance to take advantage of the...

    RX8 Renesis Rotary eSC

    Water/meth injection moves power making potential up quite a bit. It cleans the combustion chambers, smooths the combustion process and raises the octane level but it will not provide more power beyond the ~1% gain for every 10 deg drop in intake temps. You must increase ignition timing to take...

    RX8 Renesis Rotary eSC

    The 14.7 psi theory base still applies as it relates to the amount of air flow/density going into the motor, and that's independent of the accessories involved. None the less, those parasitic losses probably fall under the exponential rule as power level increases. Still far greater return than...

    RX8 Renesis Rotary eSC

    The most significant benefit to an electric turbo vs. a traditional is the efficiency. I don't believe I mentioned that regarding your posted dyno results previously. At sea level 1 atmosphere is 14.7 psi, theoretically if you apply that much boost to a motor it should double the power, until...

    P2 Supercharger Thread

    I don't own one but I'm familiar with what bad and or cheap bearings sound like and that one sounds like it could use a bearing upgrade. I read recently on the forum where someone upgraded to ceramic bearings which I'm sure will sound drastically better than that if they make a sound at all.

    Electrified from Jersey

    .91 sounds like a lot for that motor using the one I built on comparison with .7 more litres, and much higher compression on a .81 turbine. I talked to at least two different experienced turbo suppliers and T-67 was the highest recommended for my 500 hp goal. For more top end you need a camshaft...

    Very nice but, what are you doing with a 3500 when GM made 3900 motors in that small 60 deg V6 package. I built one for a Fiero, offset grinding the forged steel large crank pins to small block chevy 2.00 journals, swapping in chevy H-beam rods and using Mahle forged pistons for the LS1 which...

    RX8 Renesis Rotary eSC

    You're at a 1.33 : 1 drive ratio, that's almost 1:1, I asked about amp draw because that's a good way to assess whether you can go up or down in the ratio to either improve efficiency, or get more boost. In other words if you're still within motor and battery specs with the current setup, you...

    94 Camaros and Birds came with a 3.4L V6 option, how did you get to 3.5L, swap in a 3500 short block? I'm pretty sure I was the first to do something similar years ago prior to the 3500 front wheel drive motors being manufactured. Provide some real details and pictures of your swap so that some...

    RX8 Renesis Rotary eSC

    Great job. Do you have a blow-off valve and if so where is it located, before or after the MAF sensor. What are the details behind the challenges that remain to be addressed. What ratio to motor are you running on the blower and are you monitoring the current draw for peak current values?

    Look at the map, locate the value on the left and determine the units. If it is in meters per second (m/s) you can use the following calculator to convert that in to rpm. I've been using this bot for years, initially for traditionally boosted applications but now for trying to identify the best...

    E-charger on a 6.5 hp small engine carb requirements?

    You have to address the pressure differential with a carburetor. If you blow through the carb you will blow against the fuel flow forcing it to backflow into the tank. To offset this the carb and tank would have to be pressurized which is unsafe and impractical. Next and what was done with early...

    Phantom Eboost & gt86 going on 9 years now

    Water methanol injection is a suitable substitute, used it for years with a traditional turbo setup, I wouldn't turbocharge without it now it worked so well at supporting not only high boost, but high boost with a high compression ratio on pump gas. High compression is another thing I make sure...

    2L Opel GT e-boost build

    That's a win because an electric 2 psi is a lot more than a traditional turbo 2psi. I also have a modern engine management system to learn the tuning ropes on. Unlike OBD 1, OBD 2 engine management is torque based and not as straightforward as OBD 1. Torque based systems limit engine power and...

    2L Opel GT e-boost build

    No I am not, but it should be sufficient for a significant enough improvement over stock, given that Alex has proved the efficiency level of an electric turbo to be about 40% more efficient in his platform than a traditional turbo, so 2 psi in an electric turbo will be very close to 100 percent...
