Anyone have the specs for the singles and the duals? I tried the Supertech website but it does not list the info. The searches on here did not provide any real results either.

Thanks for whoever can provide the info.

 

Not the info I was after but thanks. I want the seat pressures, coil bind dimension, ect.

 

whos got the info??

 

Ted B. I suppose...

 

stock evo seat is 52lb
stock dsm is 62lb
crower 69lb
new briancrower 80lb? (website says 95 at 1.5, but seat height is nearer 1.6)
supertech 78lb
ferrera dual 90lb
supertech dual 95lb

There is much info from dsm boards about how high stock dsm springs can rev without hurting things. many logs of over revs in the 9-10,000 range.
The stock evo setup is better than the stock dsm springs. The behive springs and 4 gram retainer has less mass to control than dsm springs. I weighed the valve, spring, retainer, and lifter on both evo and dsm and the evo has a better mass to spring pressure ratio. And that is not including the fact that the whole spring is not being moved, only the top half. The behive spring is much lighter at the top half.

In short the stock evo setup rocks. Less friction, less heat, more horsepower. In addition to light but effective seat pressures the bottom of the retainer of evo spring comes very close to the valve stem seal. So in the case the engine is overevved the seal acts like a bumpstop. Mitsu engineers are smart.

There is a guy that just made 850whp on briancower springs/retainers/280s on a high rev 2.0.

 

Thanks. I wanted to compare the Supertechs to the BrianCrower (which I just purchased) for use with my JUN 264's. I read a few good reviews of these springs and the price was right to include the Ti retainers.

 

what kind of lbs are we looking at for JUN and revolver's springs and retainers?

 

For Revolvers:

for a good read on them... post#192 is where the actual specs discussion starts. I also believe they allow one of, if not the highest lift in an aftermarket off the shelf spring.

 

thanks bud
