Got any clear pics of the intake installed? Nice work.

We found race grade E85 to be of varying quality or at least, some had certain additives that others didn't. Had a real issue with the inj's gumming up and we had to clean them religiously. Good to flush the system out with normal petrol and leave that in the tank or flush it right through. We removed the filter baskets on the injs. Not sure of the filter grade elsewhere.

slowly getting it prepped - got a AC bracket so no we finally get the SC belt issues away. Also managed to install intake to SC.

i agree it is worth of putting sensor for re85 quality in fuel line just to avoid problems with variying quality

Mattipuh, great to see you posting again. You are my 8 valve hero on the track. SC Progress looks great.

Cheers @Noahs944 - been busy with family stuff so no time to work with car.
Ordered new Lambda sensor as old one seemed to be dead, LSU4.9 coming up. Selected the innovate ECB-1 so I get boost, lambda and fuel E85 % collected and to the ECU. Don't know if that's really needed but thought it could give options to tune engine map with more precision so why not.
Getting a slightly bigger crank pulley (150mm) prepped by a fabricator friend so I get enough tension to alternator belt. then we would be good to go to dyno.. !

That type of supercharger is expensive here. From what I understand, that centrifugal type is better for higher revs, ideal for track use!
Also, did you make your side windows or did you buy them?

Yo, that's really cool & like you say, should help in tuning.
A *hard* lesson I learned about Innovate Wide Band O2 sensors:
Never run engine with sensor in exhaust stream, but electrically non-powered.
It's destroy the sensor's functionality immediately.
Now I am considering keying-on until the sensor warms up before cranking the engine, but unsure if this is necessary (I never used to wait). Anyone know if waiting until it heats up will help the sensor last longer?
