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.

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.
