    Starting with turbos vs superchargers?

    Have you guys looked into xona Rotors people use them in stock turbo drag racing classes were you can’t use a larger turbo. By using them you increase flow on R35 Skyline by 30%over stock. Were the stock turbo can’t hold 20psi to redline. By using just the xona Rotor in the stock turbo’s they...

    my Scion FRS has 2.0L Subaru engine Rotrex supercharger

    It’s in the intake manifold by my 4 bar map sensor. My car is tuned using Mass air density tune. It only uses the MAF sensor during idle and cruise as soon as it’s making boost it uses the map sensor. If I was only 9 psi with a stock pulley the MAF sensor can be used but once above 9 the scaling...

    my Scion FRS has 2.0L Subaru engine Rotrex supercharger

    So I’m running a air to air intercooler. I got my temps mixed up from my data logs from time attack/track day that was 100 degrees during the summer. My drag numbers are at around 80-85 degrees after my burn out and they are between 114-120 at the end of the 1/4 mile on an 80 degree day. On cold...

    my Scion FRS has 2.0L Subaru engine Rotrex supercharger

    Yeah thanks for the update and I appreciate your thoughts!! so I’m running E85 and my stock compression is 12:5.1 with between 24-27 degrees of timing. Between the E85 and the high compression is why my power levels are higher than expected. I have both port and Direct injection . In the...

    Hey Guys, So I am building a new engine for my FRS . I wanting to try and figure out what kind of WHp it would make with a new larger compressor ?? I don’t know how to read compressor maps very well!! I made 355 rear whp @13psi at 7450rpm with the C-30-94 supercharger and it’s maxed out...

    Has any one looked at using a Rotrex unit sinc 10,000-12,000Rpm input shaft =75,000-100,000rpm impeller speed

    I may be upgrading from a Rotrex c30 to a c38 on my Scion FRS .so I could convert the c30-84 in to an electric supercharger. What KV motor would work to get 10,500 rpm on the input shaft and make 35-45hp? I know it’s takes between 35-40 hp of paresthetic loss for my 2.0 L gas engine to turn...

    Could you use torque amp system with a home made E-turbo

    What is the/ boost psi and CFM rating on a torque amp system? What type of power would it make for a high reving 1900cc 4 cylinder b series Honda motor ? and will it be making any boost at 9250redline? Or would it make some power down low to mid rpms and start choke out on top end ? I’ve only...

    Could you use torque amp system with a home made E-turbo

    Is it possible to use the battery/ Charging portion, and control part that the torque amp box has to power a T power or MGM brushless engine @ 48 volts on a Vortech compressor or something more suitable to make more power than the small type E turbos?
