Default Supertechs engineer replying to my questions regarding my cams/followers dying

I personally dont think that .0s30 is going to fix iyt what do you nigs think.......

Stock lenghth ferrea 600 valves, with supertechs springs and TI retainers + Stock cams (JDM) and stock cam followers





-------------------------------------------------------------------------------------------------------------------------------

The supplier that you mentioned also sells its own springs so that is why I am wondering....

At any rate, our H22 springs have around 80 lbs of seat pressure. It seems that for some reason this pressure may be too high for those cams. So you need to use a softer spring. One way to lower the spring pressure is to increase the installed height. We have a retainer RET-H1000/T2 that installs 0.030” higher and will lower the pressure to about 72 lbs. I am not sure if this will be enough to eliminate the wear you are having, but it is similar to current Factory S2000 and K20 factory engines.



VERY IMPORTANT: the kind of wear that you mention usually happens when the engines is running at very low rpms and breaks the oil film due to the pressure so a good quality oil may also help.

Stock h22 USDM cams the first time.. Now running stock JDM cams (had changed the followers too as the pads were destroyed on the vtec lobes, the cams themselves are fairing better than the pads on the cam follower/rocker…. As I mentioned they are Supertech.. ive seen them before, I just checked the valves… Stock height valves… called the machine shop too they did not machine the spring seats and did use the spring locator (stock), so everything should be stock height. Im baffled.. has ALL KINDS OF OIL PRESSURE…..



I really appreciate your help guys.



Brian

According to your description, the springs seems to be from Supertech, but to be 100% sure we would need to check the spring.



What cams are you using ?

Brian

We do not sell directly to Engine Dynamics so I am not sure if you received an H22 spring from Supertech. The part number should be SPR-H1000D and the retainer RET-K20A2/T2.

We have sold many thousands H22 springs and we never had a claim of this kind before.



So

1) first it is necessary to make sure you received Supertech parts

2) It is necessary to check that the Ferrea 6000 valves locates the retainer at the correct installed height of 35.50mm (1.397”)

3) Some aftermarket camshafts are too soft and abrasive for stiffer than factory springs



Best regards

If it helps transaction #: 3mk33627p6761203c





Guys:



I bought a set of SUPERTECH Springs and retainers from you (in addition to some other stuff as well). Great service as far as getting me my item…. I now have a problem…. It seems as though the springs are TOO stiff. I have been in contact with Supertech (actually ccing them to this email…. I did NOT receive an invoice with a part number from you, and need the Supertech part number so that we can further troubleshoot the problem.



Could you please get in touch with me soon, as In put Only 1500 miles on my 10,000 dollar motor, and the cam followers and cams are getting eaten alive (ive already had to replace the cams and followers.. Its happening again)….. Have verified its NOT oil pressure or lobes not getting lubrication… I have kick *** oil pressure, yet the VTEC cam follower lobes appear to be eating themselves alive. This motor has a lot of money in it, it concerns me that the cams/rockers are basically self destructing.



This is a freshly built Sleeved H22 running CP pistons with OEM bearings and EVERY BOLT/SEAL/etc.. brand new… Balanced blueprinted. I appreciate you guys help in trying to rectify the situation. They are ordinary H22 cams that should cause NO issues… they didn’t with the stock springs….

Ferrea 6000 valves, Your spring and retainers and a mild port and polish… There shouldn’t be any issues







PLEASE PLEASE PLEASE help!!! Motors going back in the car this weekend, and I need help!!!








PS (thanks Martin@ Supertech)

There's no spring pressure on almighty V-Tech lobes/rocker arms at low RPMs. :1

That being said. Maybe there is an issue with the LMAs.


Also another thing comes to mind. Retainer to guide clearance. I wouldn't think it would be an issue with stock cams, but maybe the underside of the retainer is too long. I should destroy your valve seals first though, and it ought to make a hell of a lot of noise.

IDK Just some ideas.

I don't really get the point of stiffer springs on a VTAK engine. Valve float should be pretty minimal the the LMAs there.

Turbo cars require them as power, and rpms, gets up there. You won't turn 10K in a turbo Honda without 100+ lb springs, whereas the NA ones just need correctly designed springs that follow the cam lobe.

Thermal mass, my bitchtits.

Ever noticed how modulus of elasticity changes with temperature? The exhaust valve is the number one focal point of thermal assraping. Can you connect the dots?

Lol, slow down there JD. I haven't made it to any of the good classes yet in my pursuit of an Engineering degree.

Basically you are saying that the stiffer springs are needed to counteract the increased weight of a much beefier valve, which is deemed necessary to handle the increased EGTs.
