    Today themes RIVA Valve Train Upgrade Kit


    I hope attention to the issue because a lot of friends do not know this subject RIVA Valve Train Upgrade Kit
    1 - Pressure Valve Train normal 50 PIS
    2 - Pressure Valve Train bilateral 140 PIS
    3 - Pressure Valve Train unilateral 80 pis
    140 PIS disables the engine and head in the near future I lost 3 engines to now because Kayed, who holds valvs may crash and cause a lot of RPM and high pressure on the Bustn of better and better to put Cover Valve Train one ( 80 PIS ) , not double ( 140 PIS ) this for the continuity of the engine
    And I will put pictures of the engine unemployed

    Here are some basics specs about the oem and Riva upgrade kit:

    OEM:
    • Spring install height: 1.343"
    • Base cup thickness: 0.039
    • Pressure at install height: 58lbs
    • Pressure at full lift: 110lbs (max lift on SHO cam = 0.347" and HO cam = 0.365")
    • Spring rate: 137lbs / inch
    Riva:
    • Spring install height: 1.292" (titanium retainer sits 0.020" lower than oem steel retainer)
    • Base cup thickness: 0.069"
    • Pressure at install height: 88lbs
    • Pressure at full lift: 185lbs
    • Spring rate: 274lbs / inch
    Allow up to +-8% error margin on the above numbers to account for spring pressure differences, valve seat wear and valve lenght differences.

    This poster has entered the 4 stroke performance threads lately. My only gripe is his/her objective. Posts are very hard to understand and decode. S65_42000 may have some useful information and I'm thinking I'm being kind here, but what good is any of it if we can't understand one bit of what it's about or where it's going?

    What cereal box decoder do we find the damn decoder to make heads or tails of this mess. Now that was kind of being a dick, but cmon son.



    Wait SHOBiz sees this.....LOLOL

    I think that
    Large sprink Best than Dger And not both
    And I think that the holder must be the good kind
    And from better to switch to valves heretofore titanium valve not broken, Textile and weight of regular Allowalat
    Dubl Asprink beans Modevaeld this what I think
    Engine Super Garg always what to low-pressure
    turbo need to high-pressure
    Thank you for all
