Modifying my TO4S bb to a 67mm yay or nay
Current setup
Hks to4s 44mm tial open wg, 3 inch exhaust
1680/850
Water Meth 70/30
Blitz fmic
Aem
SP REW w RA super seals
Car made 440rwhp 368tq at 18psi. Tuned by ray wilson pfs.
Long story short, sucked in plastic and trashed compressor wheel.
Its being rebuilt now. I am given thr option to go with a 67mm wheel, over the previous 63mm
Turbo previously maxes around 61lbs of aair and around 460rwhp.
67mm should allow me to near 500rwhp higher boost.
My question, do you guys believe if I can upgrade the wheel and gain efficiency to 20-25psi, is it reasonable to retune at this level on pump and water/meth? Or do I need straight meth? Or am I simply just asking for damger above 20lbs without race gas?
In otherwords, if I have enough efficiency to push high boost, what's the limitation of water meth 93?

I'm currently running 25psi on preturbo water/meth and 93oct...well I should say WAS running that until my clutch really started crapping out lol. Either way, knock was extremely low for me under boost...I believe it was around 9 or so on the PFC knock scale (just for reference regular noise cruising around out of boost with my car is around 35 to 40...and thats mostly due to driving on crappy roads or hitting a bump lol)

6766 dbb precision turbo, 850 prim 2200 secondary, ngk 11 heat range plug, hks twin power, stock coils, streetport, power fc, wannspeed preturbo injection kit 50/50 water/meth, large smic. I plan on changing to a vmount though because I don't like the higher intake temps in this hot weather, its getting close to 50c after a 1-4 pull but instantly goes back down once I cruise.

I run 50/50, 93 pump with 100 race up to 20 psi. Above this, just for safety, I'll use
fuel of 110, or Q16. I rarely run the car over 19 psi.
Just make sure your AI is working correctly, and all will be good.
