valve spring pressures

[Celica RA45]

ok whats every bodies thoughts on being to much pressure and to little pressure
these would be seated and cam nose pressure
will give you the valve sizes and then give you the valves in weight to work out what you can come up with
inlet 35mm ----- exhaust 30 mm ---- next inlet 35.5mm ---exhaust 30.1 mm
22grams --------- 17grams - ------------ 48 grams ------------------------- 42 grams
these are the weight s now the pressures that you guys would think could work
seated the 1st inlet 55 lbs seated 165 on the nose the exhaust 40 lbs and 160 on the nose
the next inlet 80 lbs seated and on the nose and 200 and 60 seated and 165 on the nose these are the pressure im running on the 1st set of valves being using this for about 16 months now abd the shim clearences have closed up 1thou in this time the new motor will run 80 and 200

also glenn...

thats basically my valve weights and spring pressures... with your extra lift taken into account in my comparison

from my discussions with the spring guys this eems right on the money

i am thinking that you shouldnt be using more then 65 lbs non race.

Race, certainly above 80 no more then 95.

its verey similar to what i use also.

75lb on the seat and approx 180 at full lift

Minus the 30 or so pounds of boost pressure when they're seated!
