no.....

the deciding factor for HP in ANYONES setup is their weakest link. whether it be injectors,maf, turbo, cams, or what they are tuning on... This guys got 550cc injectors and a piggyback thats only good for a 50% fuel over lap. he needs to ditch both of these if he wants to get more out of his turbo setup. you can throw a t67 on a fullllly built SR and if you have 550cc injectors your WONT make more than 350-380whp safely period. the injectors will be running static.

all in all you have a nice little setup man. if you want more than 350whp id get some nismo 740cc and a pfc/nistune/ems

Just look up a compressor map of the turbo your using and you can guess ballpark power figures.

ALL that matters when making peak power is how much your turbocharger can flow, and will the engine handle that flow with the fuel type selected.
everything, including fuel, is up the owner to supply. We are only SUPPLYING the necessary fuel, though. It is not "making the power", peak power comes from peak airflow, properly used.

Ive never even seen a BC stroker kit in use. Do you have any pictures of the parts, the assembly, or any information about what was done to make them fit (modifications to the block) and any information about the balancing needed?

And posting specs like that without posting pics or vids is pointless. Its just numbers watch I can do it too
RB30DETT Stroker kit, 280 duration camshafts oem lifters
8,500rpm E85
Garret GT42 1.06 a/r turbocharger custom in house manifold
Chevy powerglide transmission 4,000 stall with Trans-brake
OEM S15 Differential

940~ RWHP @ 38psi boost

wow what a shitty made up setup.......

a twin turbo RB30 with only one turbo and and an automatic chevy transmission.

Lol. You want to hit 400 with Co-g@YMETIC and neo? Talk about no reliability.
