Engine/Transmission (1998.5 - 2002) Anyone have any specs on valve spring high rev kit???

Anyone have any specs on the valve springs people are using for running higher rpm's.

Most of us are running F1 Diesel springs.

While I will most likely end up with those, I still find it tough to swallow $600 for a set of valve springs.

Having built a race motor, and been around a LOT of racing, even the real high end stuff doesn't add up like that.

Mainly a low production vs. high cost issue. But it still chaps.

The 600. 00 thing is hard to swallow, my machineshop guy can come up with it for a ton cheaper if i had some specs.

The thing of it is that anbody's machine shop guy probably could. If we could get the specs then there wouldn't be any need for a lot of stuff. That's the reason they cost what they do - the supplier has got r&d which is time and money. Just one of those things.

I have been down this road... ... I just pulled a bunch of broken springs off a 24v truck that were supposed to be the top of the line components. These springs ran over $1200 for the set but were an inferior product.

Don't get me wrong, I want the BEST stuff. But I think that the cost involved is higher then it needs to be. Besides, one would think they would sell a LOT more at a more reasonable cost.

Either way, I will only spend my $ on a reliable and proven product.

 

[AFarmer]

I will say this - not to offend anybody - a guy told me when I started out in putting my truck together that if you wanna play you have gotta pay and boy I have paid for what I've got. I paid $650 for my springs and I didn't look back because I knew what I was buying was the best and I haven't nor will I ever second guess the product that's going on my truck. You guys know good stuff is just dang high.

 

[Froadin]

Yeah, that is one thing I like. If I pay $600 ish for the F1 springs, I KNOW I am getting great stuff. No doubt there.



But lets face it, there are only so many kinds of spring material, rates, clearances, etc. out there. I don't want everyone to undercut the F1 stuff, I would rather F1 stuff be REASONABLE in cost! I really would think they would sell a lot more at a fair price.

Heck, there are a lot of people running aorund with stock cams that could use the better springs. Let alone everyone adding up the total cost involved with a bigger/better cam, then add in the springs, etc. (my case, the total cost is what gets me).

 

[Sea01Cummer]

I don't mind paying for what i get but man 100. 00 a cyl for valve springs is getting a bit greedy. My point is if it was high rev springs for a ferd pinto there is no way the market would pay 100. 00 per cyl. Since this has high performance diesel labled all over it, sky is the limit. There is no doubt F1 puts out fabulous products and his price is probably being passed on from the last guy that gouged him.

 

[Froadin]

Especially when you consider that the open and closed pressures are LOW compared to most other engine types. Valve lift is also pretty darn small as well. Nothing here should be crazy in design. Just making sure you use a high quality material, give enough clearance for high rpms with bigger cam specs. Not rocket science here.

Of course I get my knowledge from gas engines, not diesel. So I don't know if there are any real things I am missing here though.
