GROUP BUY: 264 degree cam regrinds

[Adam.Findlay]

What is the standard lift and duration, can't find that in the other threads.

And I'm guessing this lift still needs new valve springs?

I dont know that yet will have to go and get a print out of the stock cams profile next time I am there and yes 9.8mm lift still requires a change in spring. Peter said that the stock springs are very low in pressure and even just changing the springs may result in a power gain at high rpms

i would be very interested for a group buy later on this year

I would also be interested later on in the year.

for those intrested in a group buy later in the year

a few questions about the springs to be supplied,

are they just stock evo springs? uprated evo springs? something else?

would standard evo springs suit the reground cams?

[Adam.Findlay]

uprated evo springs. I can get the specs for you if you so wish.
stock evo springs might do the trick but could be pushing the boundrys as they are very similar to vr4 springs but with a stronger spring constant

In for the first group is officially closed. once one of the members or myself has installed the cams will post results and possibly someone may go for a dyno run to prove the cams worth to the 2nd group

Can you please also ask Peter to clarify his thoughts regarding issues to do with rocker clearance:


Several sources (in person and online) are telling me that because the base circle size is reduced, clearances to the hydraulic lifters is increased which can either lead to noise, or the requirement to shim them in order to keep things in check.

Thus I'd like to know how much additional clearance is created and if/what he believes should be done about that and why.

Thanks.

will do trent. next time I go and see him which will either be wednesday or thursday depending on when your cams arrive at my flat

[Adam.Findlay]

trent.
peter told me today the regrinds have been desgined to work without shims but if you are worried about it you can remove the circlip off the top of your lifters (circlip is only there to hold the lifters together when they are not in the engine) removing this clip will allow the lifter to pump up an extra mm or so.

Update for those people who are intrested. the first set of reground cams went into carl's (aka patron999) galant today the performance increase is quite large, very very small sacrifice of low down torque for a masive gain in 4krpm+ power. it seems to help the turbos flow a little bit more up top also. carls galant felt like it pulled much harder @ 10psi then my legnum does on 15psi of boost. hopefully carl himself can post up soon with his opinion after a bit more driving time.
Will ask carl to update again after he has flashed KSmods extended maps on and tuned the fueling and ignition maps. hopefully there is more to be pulled from it again

also carls galant remained lifter tick free with the reground cams installed
also found out the valve springs supplied are Brian crower brand
Spring Pressure: BC1100 Seat: 1.550" @ 84 lbs / Open: 1.000" @ 235 lbs / Coil Bind: 0.935" (no machine work required)
