Thanks, am amazed myself knowing from where I started, never believed back then this would all be possible, or even that the engine would hold up. Every time I have upped the power a bit was always scary for a while as no one else had this kind of power levels before. I will leave it as is for the coming time, am so happy with how the engine runs/purrs, now I want to just enjoy it for a while.

I have 2 other changes that support these power levels, reground camshafts and sports catalysts, and these allow higher output without having to spin the supercharger faster. The latter is not out of breath yet, and I expect a good gain again by swapping pulleys, but as said, these are serious power levels, and although you determine yourself how fast you want to spin the unit, this is not something I will recommend to do.

Am driving with this setup already since December last year, so this way I can at least show that that lower power levels with my kit seem very feasible.
But remember, these power levels are for street driving. For track/race usage I always recommend to use a slightly larger upper pulley to lower the power a bit (you could even swap it on the track). Sustained long high power usage is a whole other story then street driving, where within a couple of seconds you are already flirting with local speed limits, and where you have some cooling time between power runs.
Engine is going now to 6200 rpm, if I would extrapolate the figures to 6500, it would be arround 550 rwhp, so it is somewhat tempting. The supercharger itself is only running at 12800 rpm so lots of room there.
For now I will just enjoy, and probably plot a plan for the winter ;-).

Am still driving a dream, not sure what reality is anymore ;-)
I have a LSD already for a long time, so don't know how it would drive without, but even a stock car could already use a LSD. With my sticky tires (285 wide, going soon for 295) and LSD in 1st you can easily have the wheels spin, no matter what rpm, and no full throttle required. In 2nd it is already more rare and nonexistent in 3rd, however this all assumes a dry sticky road of course, in wet you need to be careful at any speed.
So it isn't that bad actually, and with the clutch type LSD I can even drive safely with traction control on, and take T crossings very fast without the traction control cutting of power for half a second…
