Got an aeroforce to watch for kr and the shop has offered to retune for free if i change something so i'll be back eventually.

Got the 3.4" pulley on today along with a fresh belt. Car seems to run quite well with little to no knock. Also have a set of colder plugs coming and then i'll be back to the shop for a retune.

Awesome, just be easy on it until you retune. Keep us posted on the gains!!

I slowly worked my way to full today and still not much knock, saw 2 degrees once and otherwise it was usually under 1, plugs and retune should have that covered.

Kr isn't bad at all for not being tuned, still for sure have it checked though. Hopefully the smaller pulley/ increased boost get you happy with power you want.

What are you wanting to make power wise anyway?

No idea really, my goal was a 3.4 pulley but if the gains are like last time i'm not really getting anywhere.

Well both of your pics are not showing up for me on your first post so I'm not sire what your car made before the mods were done. Don't look for massive gains though, maybe another 10whp and I bet that's about it.

To get around 300whp you will need to be intercooled, 1.9 rockers or cam, 3.0 pulley, headers, etc. A guy I know has this setup and made around 315whp

It made 207wheel with just a cold air intake and then 216 wheel with the exhaust mods and 3.6 pulley but it didn't gain much boost.

If I had to guess I am gonna say 220-225whp with the 3.4 on a semi aggressive but safe tune. You will see another nice jump in torque though is my guess.

Another problem with these cars is the sc makes tons of heat, the quicker you spin it (smaller pulley) the more heat it makes. As air temps get warmer it starts pulling timing to prevent kr but in return pulls hp as well. You are seeing nice torque gains as torque comes in quick and before heat soak, peak hp comes up top and that's where you are heat soaked so not seeing as high of gains. Next mod for you would be investing in a nice intercooler if you want to continue modding or going e85 is the other option :)

Either way the torque gains will make it feel way more "push you into the seat" and will help you get moving quicker down low, the top end will feel a little stronger but you will see where it feels to sorta "die off" and at that point is when your getting heat soaked.

Side note, on that dyno what gear is he doing pulls in? And when he goes wot on the dyno is the car downshifting? He should be locking the trans in 3rd to prevent the downshift via hpt and not letting it upshift either. Shifting on a dyno makes numbers way off most of the time.

Not sure on the gear, but i believe it downshifts before he makes the pull.
