DonF where are you boss?
I've PMd you several weeks ago but doesnt got any reply from you

or any one here, I need suggestion about weber setup for my 2.0 ITR with skunk pro2

last setup was stock short block 1.8L ITR with weber 50mm 4 barrel carb, with 11.8:1 CR (setup was in my sig : https://honda-tech.com/zerothread?id=1654882 ),
and with those previous setup, donf suggested me to run 46mm chooke with the correct jetting, f16 emulsion 200 main jet and 215 air corrector jet size..
and it run wild !! 260 crank hp on dastek dyno (i know this dyno inflated, but im very satisfied)... Thanks donf.

but now im ready for my 2.0L short block with 12.5:1 CR that would be 'fire' up this week... but i dont have any guideline for the carb setup...
-what chooke size should i run?
-how about the main jet size? how many increase should i did from the last setup (i need just for starting point, and the dyno tuning will do the last touch)

need advice....

thanks Guru

 

PM'd

 

If you provide me you single cylinder displacement, and max rpm, I can give your proven guides on venturi sizing. Do you have an Innovate LM-1?

 

Bisi is one bad ****

 

Sir Bisimoto, my single Displacement is 499.3cc (84.5mm bore, 89mm crank)
and my max rev / shifting point is arround 8700-8800. And yes, the dyno shop use innovate LM1.

Thanks a lot Sir.

DonF, Pm accepted.. thanks a lot.

 

Your best bet would be a 42~43mm venturi in a 50 DCO/SP weber. This is sourced from my own proven algorithm.

 

i have h22 with unibody and doest pass 2000 rpms seem likes its fluded can any body help

 

Really, 4 year old thread that probably has nothing to do with your problem. Start a new thread for you issue or search maybe.

 

LOL,,,

just realized, Don Flores and Randy RMF passed away???
I see on someone here the signature tell this things.

RIP !!!! May you both blessed in heaven !!!!!! :sad :sad
Donf : He helped me with lot of knowledge about port, carbs, exhaust design.
Randy : I always admire his exhaust, even now im still building his last header style.
