I finally drove the car for 500km after the SC is installed.

Before the car is in operation temperature (90 – 100c Oil Temp), car still have idle dip and automatically rev up to 2k RPM at a complete stop. After the car is in operation temperature, no idle dip. Is this normal?

When I rev up the car at around 4500 rpm, it feels like the car has an extra punch (way more obvious than without the SC).

I still haven’t had a chance to datalog the car and send it to Matt.

Get the tune checked. Should not have idle drop. Possible vacuum leak.

level is about 1" from the top or thereabouts, you will lose a tiny amount over time as vapour as the cap isn't sealed

The idle dip is hit and miss how quick it learns. Sometime after loading and map it learns really fast other it take ages. Same map.

There is a fair surge after going past 4k ish
As the torque picks up a bit.

The item "Cosworth FA20 Undersized Supercharger Pulley (63.5mm)" is invalid and has been removed from your cart.
Looks like the online ordering for this part is still not working. I had to have mine manually added to my order. The system still thinks it's part of a bundle.

It took hundreds of miles and over a week but I got one more CEL. P0456 - EVAP Control System Leak Detected Very Small Leak

I'm going to go back over the system and replace the hose clamps with worm gear clamps to ensure everything is tight. No drivability issues at all. Car still runs great and is getting good mileage. I haven't gotten any other codes since Matt deleted my previous EVAP code from the ECU. I'm not sure if I have an actual EVAP purge line leak or if this ECU is just extra finicky.

Running the kit for 400km now and everything run well so far. So happy with it! Do you find that cold start are a bit less aggressive than before the mods?
I also thinks that a reason why I don't feel much of a difference in some of the power band too is because the car was already modified before I put the SC (el Header, full straight exhaust and OFT), so hp increase was a bit less of a shock.
A thing I like too is the tune, my car do less random backfires than with the OFT (better AFR or timing maybe).
I have a concern about the coolant concentration, 25% of glycol is good for summer but what about winter? is there a reason why the ration is so low, is it just performance wise or 50/50 concentration would be hard on the hardware? I live in one of the coldest city in Canada during winter (outdoor temp can hit -40 to -50 degrees Celsius) and the car will be park outside. I would prefer to drain the system instead of putting coolant that would ware it.

Do any front strut bars fit? Anyone looked into fabbing a curved one?
