Strictly for the F23a1/ F23a4.
I know there had been lots of threads but most of them go nowhere. Everyone says a 100% increase is power is about the max this f23a1 engine will hold "reliably". Or like "dude it can only take 8 psi". Please dont comment saying they have weak ringlands so only 200 whp is safe. Or someting like "mines went to 225 and blew so it should be safe around 200". Please dont say that every engine is different so hp levels will vary. All these examples have nothing to do with how many peole went over 300+ whp mark. They only have to do with how many people DIDNT.
How many of you have been past the 300+ whp mark. Ive researched and concluded that about only 4 people have hit whp 280-350. How many others have hit this mark reliably and successfully for at least 1-2+years. Again, please don't comment saying something like it wont hold even 200 hp because my car blew at 200. Please don't comment saying its all about the tune. I already know it is. I just want to know statistic wise of how many people hitting that mark and how long their engines lasted. I want successful stories not the failed stories. If you hit those power levels for at least 1+ years i want to know. No failed stories just the successful ones. Im planning to hit at least 300-320 with arp head studs and water methanol used to increase my margin of errors. I figured that if 10 out of 30 people hit the 300+ hp mark then most likely those 20 out of the 30 did something wrong (bad tune, old worn engine, wastegate stuck close, bad gas, etc etc). Another dumb exaggerated example: if 40/40 people blew their oem stock internals and never made it past 500hp. So to "conclude", most likely the f23a1 cannot take 500whp.<- that was an example so don't flame me for that.
It would be really cool if those who have hit the 300+whp mark would comment in. Live input with direct experience is always the best stuff.
Dyno charts with Rpm readouts instead of mph would be cool too if anyones got some. Want to see a few dyno charts just to show where the power band starts and ends per diff setup based upon tuning, turbo manifold, exhaust sizes and turboes used.

make or break
Its a pain but next week i am going back to cali to tackle the turbo setup and fab it all up then street tune. I wonder how she is going to sound with 3" exhaust all the way to a dual 2.25" 2013 wrx subi exhaust with quad tips having its muffler interior re worked on. Cant wait. Prob wont squeeze out the max hp till i get her back to Utah and do yet another street retune for Utahs higher elevation then some dyno hours then some more street tuning. From then on its boost till i blow. Thank god the engines are $175 complete with no trannies at the junks in utah with 170k mile engines.. pix of parts coming soon onto this specific thread.
