Another new product, High Rev Valvespring Kit!

[niterydr]

We were very tired of waiting for our perferred vendors to get titanium in stock, so we decided to work with a new vendor. With there help we came up with an upgraded valvespring that should easily support 9000rpm and most aftermarket camshafts (except the fp3x and up).
These also come with a Chrome-moly retainer.
$279.00!!!

We do not have them in stock currently, as we haven't placed an inventory order, but they are a week out if we need them.

Any idea of the actual spring pressures?

Work for those brian crower 280's?

I would have to see the profile on the 280's. Lift, duration, ramp angles. I haven't tried them yet.
What spring pressures do you want Jet, and at what lift?

[A//// Guy]

Can you get these for a 95 M3?

[niterydr]

I can look into getting springs for you peter.
What specs are you looking for? Upgrading cams? Just pm me.

[A//// Guy]

Probably keeping the stock cams, because anything aftermarket is 1500 for a set... But a different chip will let me rev higher, and Im doing lifters anyway.

[niterydr]

Cool. How high are you reving it? Do you have a valve spring compressor?

[JET]

Just wondering so people can compare them to Crower's, etc. My Crower's are actually doing ok with the 415's, but I would feel safer with something a tad stiffer.

[Pushit2.0]

I have measured Crower and stock springs for dsms and the Crowers are about 70lbs at an installed hight of 1.57" and a stock spring is 66lbs. Then if you have a .4" lift cam that would be 190lbs of pressure vs stock of ~170lbs at .4" lift. So Crowers are about ~11% stiffer at .4". The LSE spring/retainer combo will work for anyone running a Crower 64415-2 cam size and reving to 9000rpm, then we can size/come up with a dual valve spring kit. Then when Ti becomes available we can sell that also.

The car revs to 7 with a Dinan chip in it now.. I would get a different chip that will either leave it at 7 or raise it to 7.5.

Either way, I kind of want to replace the stock springs with new ones or nicer ones. The car is getting close to 100k, so I figure if I replace the lifters, why not do the springs in case I decide to mod the car more in the future.

Alright, why the chromoly retainer? Are you making it thinner than the stockers?

Cheaper and more available...the chinese have been buying up all the titanium. Plus the weight difference isn't THAT huge for most applications.

[JET]

Chromoly isn't lighter than carbon steel, so I was just wondering why these would be better than the stock retainers?

Once we get them in, we will weigh them to see the difference.

[JET]

Chromoly is stronger so you could take some material off and keep the same strength. A huge weight savings would be a groove going up between the valve and the spring. That material does nothing in there. You could probably save 25% of the weight in there.

Since it appears that you're selling these now,

do you have any of the weight numbers?

[95talonracer]

So will these work for the Crower Stage 3 64114 cams? PM me if they will.
