Quote from: "m1tch"What rpm is the rotrex rated for? Guessing it might have gone overspeed if you are revving to 8.5k?

Unlikely.
You tell TTS your max engine revs and crank pulley size and they send you the appropriate pulley for the unit.
It it's been over spun it will be their fault.
FYI peak impeller speed on the unit in question a C30 94 is 100000 rpm.
First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me.

Will be interesting to see what the failure was then, the drive ratio is 1:9.49 so at 8.5k rpm its spinning up at 80,665 rpm so well within limits.

Also just noticed they offer a VC8 variable RPM supercharger - electric motor driven supercharger - although only for the very smallest size, might be an interesting development.

The way I understand it you have a pulley on the rotrex which means it hits 100k rpm impeller speed at 8500 rpm engine speed.
It uses an adjustable BOV to bleed off boost above a certain threshold which on this setup is 13psi I think.
Will be having the same thing on the V6 but much less boost.

Rotrex has been returned to the factory for them to look at. Looks like it make have cracked internally. As some one has already mentioned, fitted with correct size pulley etc, supplied by them so am not expecting any issues with a replacement

Been a long time but am collecting car from headcase in the morning. New calipers and a working handbrake, polybushing and a new rotrex charger fitted. Been without car for 3 months due  to dispute about the rotrex unit failure. Was told that it was not a warranty failure....... Much credit to Headcase who in the end got a replacement unit under warranty

Can't believe how long this has taken or how difficult rotrex have been about it.
It's the same as mine all components sourced from TTS an official authorized rotrex dealer.
Great product completely let down by rubbish customer service.
Here's hoping for a trouble free future.
Best of luck.

Today, Taking my Aussie brother in law for a spin, pull away from lights at motorway roundabout, old girl in Suzuki Wagon comes sailing through a red light, anchored up in time for her to miss me!!!!!. 3 Mins later, big rear end moment on slightly damp road on cold tyres when I booted it in second!!!
Apart from that all seems to be good again. Just now need to get the map altered to match the new fuel pump. Also need to get 5th gear sorted. Bought box with 5 celica 2zz gears with an MR2 6th gear in it, Turns out that I appear to have and MR2 5 gear in the box, Bit of a drop when you change from 4th to 5th when at the red line.
Feels tighter now with the poly bushed suspension as well .
Think I have now reached the point where there is now nothing left to do to the car

Yeah, at that power level, 2nd needs caution even in the dry. Keeps you on your toes!

Day of confusion!
Went to get a tweak on the rolling road to get the best out of it since having a new fuel pump fitted. first run 187 at the wheels taking into account that a 20% reduction from flywheel to wheels would make it 235. Bit surprised as i have a printout from the same rolling road showing 349, less your 20 making it 279!
Was advised that there must have been an error on that print out. Did wonder why it didnt feel as quick as i tbought it should feel!
after a few tweaks is now at 277. at the wheel 221. 42 bhp gained. feels a bit quicker on ride home. will try and do a couple of runs with the race logic at some point
