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...

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...

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...

Thanks man🙏

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...

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...

Rotrex C30 Rotrex C38 C38R https://www.rotrex.com/centrifugal-superchargers/

That would be awesome!

here is my 12 sec run POVon YouTube

Here’s my Rotrex Supercharger Scion FRS On E85 making 354whp 7400rpm at 13.7 psi . Using the C30-94 Rotrex Supercharger.my best 1/4 mile run is a 12.7 at 112-113. But I never launched hard highest is 4000rpm and my power doesn’t really start until 5500-6000. Didn’t want to brake an axle on my...

Sorry I never so this reply lol Is there not lot drag racers on the forum

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...

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?

Since I don’t have any machining equipment it’s going to be harder to do the conversion to a brushless motor than I Thought. Not sure how to adapt the Tp motor cause I took everything apart and the Impeller seems to be pressed on the starter shaft bearings then a 13mm bolt and washer . Here’s...

Here is the Esc750 T88 housing ,T18A10 impeller, 126mm major, with 88 mm inducer. 4 inch inlet and 3 inch discharge, A/R. 75-1.05 with 15 Hp starter motor @ 48 volts.

I found these old pics and articles from Thomas Knight who is the person that built my E Chargers. I have esc-750CFM direct drive and esc-550CFM but it’s not Direct drive it has higher boost cause of the big gear on the starter and smaller gear connected to the impeller shaft driven with a...

I’m not sure about the compressor maps. They were built so long ago and the original company’s name were ground off and painted over . I may be wrong but I thought the smaller one was a vortech and the big may be a Garrett. Also the Impeller were custom made and balanced with red and blue...
