Anyone out there know if a YSi Trim can supply 14 or more pounds of boost on a 555 CI BBC? I want to shift and go through the lights at about 7000-7200 RPM. Am I going to run into a impeller speed problem?
Thanks

you should be fine,
Vortech's Big Block carb kits come with a YSi now.
We are building a 434sbc with a YSi and its cog'd for roughly 15psi at 7500. the YSi is good to 30psi, it should feed your 555 at that boost level.

Sweet looking motor! I am going to purchase a Vortech BBC carb'd kit. I do have a few questions for ya.
Who sells the cog kit I saw on that sweet 434? Is it a 8MM?
I noticed your using a bonnet on the carb of the 434 vice a box. Is there a advantage to one over the other?
Thanks for the advice.

PS When you ran your 8.96, was it with a YS trim or a X trim blower?
That appears to be a Vortech 8mmx50mm cog belt set up. I would recommend using a strut brace or a tower brace to help elliminate any flex. It may not be a problem at those low impellar speeds.

yeah thats kinda in the works.........its a chevy nova and there isnt really anywhere to run a support strut to.
The Blower and tensioner cog is Vortech, the crank is RCD and the tensioner plate is a custom one we had made to use the vortech stainless arbor. The stock SBC kit uses a spring loaded tensioner. here is a new updated pic as of yesterday, car is still being assembled.

Spence, It looks as good as it will probably run. Are you going to take this to any events
