Hi
buschur 2.0L pistons are 10.5:1 comp ratio
i think this ratio pretty high with hi-boost set up
If I set up :
GSC powerdivision CNC PORT HEAD (bronze guides 1mm valves inconel ex valves 11000rpm springs tatinium retainers etc..)
BUSCHUR 10.5:1 piston
BR aluminuim rods
eagle 4340 2.0L crank with bearing set
race balance eleminator kit
HKS 280 IN/EX cams

AEM EMS with twinpire and pancil coils kit

BR buschur HTA GT35R kit with BR tubular header

If i use 10.5:1 BR piston what can i use maximum boost on 91 octane pump gas and 108 octane race gas
also eatimate each HP

I haven't decide piston comp ratio yet but what can i have benefits comp ratio choosing if i use 10.5:1 and 8.5:1 or 9.5:1
I will make 91 pump gas and 108 race gas maps
My goal is 650-700 WHP using 91 pump gas at 10,000RPM. that's why I will not use stroke kit

the most curious things what will be different each CR ratio on this set up boost
what is best choice on my goal
can it possible to make 650HP 91 pump gas on this setup ?

I was send BR to ask this things but they answered me simply (depend on)

thanks

1000cc RC injectors and may be add 70mm big bore with magnus intake manifold or some other simailr brand intake manifold

Your expectations are way too high and at 10,000 the turbo is done.

yeah. depends on if he's after a power goal a time goal or an rpm goal, readjust goals/turbo/rpm to suit

10.5:1 seems to be a little high of a compression ratio for California **** water (gas). Any reason why you chose that comp ratio?

I asked buschur racing about different ratio they have one CR 10.5:1. They said " we only have one CR 10.5:1 and using this CR all of our mod car"

I didn't decide CR ratio yet. I'm asking here for find out better choice of CR ratio using CA 91 pump gas

what can I expect HP this set up ? anyone have idea?
