need an advice guys...
I have some parts to make my rappy faster but it seems to me that I badly need a +3tb....
Any ideas?
the list:
hc 3
+5 crank
piston cp 11:1
THX
you already have those mods? then a +3 will help. :thumbs:
Depending on what you're looking for.
For sure the throttle Body will help though!!!
Is your head ported?
head is not ported...and wont be soon :rolleyes:

now I have big 3 mod ( pc3, duals, gytr)
the other parts are brand new and waiting for their time...just want to install everything at one time
the cam will give you more airflow into the motor, so a bigger TB will help a LITTLE bit in that respect. You will see greater gains the more you do to it.

LITTLE BIT ? ???
is it worth spending 200$ on ot?
With my mods a +3 TB made 3+hp (770cc), on a stock bore your +5 crank will give you about 3 to 5 hp and the cam will give you a little up top. It will all work better with the +3tb
your best bet is to wait I guess. a higher flowing TB will shin better when you port the head IMO.
It seems a +3 tb is woth 3ish hp or so. This a dyno graph with Bo's track port head, 105 bore, x-2 cam, and 14 compression.
This is before and after only changes made were a +2tb.

I would imagine that it'd be less on a stock head though.
ok. thx for the help guys :thumbs:
we use +3 tb's on bikes with just intake duals and pc....they add about 2 hp on a bolt on bike... the bigger the build the more the restriction so hp per $$ its a good investment....even on a stock head
