Need higher comp?

[francky2000]

Here is what happened to me:
Dropped the rappy for the rebuild of my engine and installed a new hot rod crank at the same time.
Now i got the head ported by BO, +2Tb, Hot cam stg3, trinity intake..but...they didn't fix properly the intake sleeve. so the engine has been sucking dust and sand for about 30 hours.
They are ok to open it and check the piston, rings and cylinder. since they open i am thinking going for higher compression ratio but i am scared to have too much vibration.
So what would you recommend? stay with stock piston?
Or go for 11:1 (I have to run it with road gas) but which brand will suit the best? (Less vibration)
Is the HP gain worth the money here?
thanks

is that a stroker crank (+5) ?

[francky2000]

yes it is

[Colorado700R]

the if the piston is corrected then 11-1 will be ~11.7-1 so you should be OK for Premium pump gas 91+ octane.

Go 11:1.  I have a similar build with the hotrods +5 and run 91 all day with no problems.

[francky2000]

What brand of piston shall i go for? CP, Je, wiseco?
What would be the expected gain?

[dabigbratj]

id go CP

+1 on above I have recently installed a CP 11:5:1 along with a bo's P&P,KDS +3 TB and RJ cam and im very happy with my ride now

how about vibrations did you feel any difference?

I run a +5 stroker with 12.5-1 and feel no diffrence in vibrations.

[francky2000]

12.5:1!
can you run it with road gas?
did you need to change the spark plug?

[Colorado700R]

no, i run race gas mixed 50/50 with 91 premium, but I ride at 8000ft Altitude

no plug change required

No difference in vibrations,just raw power  i also run pump gas 

[francky2000]

I couldn't find any cp piston here 
only wiseco or je..I took a wiseco 11:1 with the new coating on the skirt i hope this is good enough...

Wiseco is #2 in my book so your good.
