Hypermax Hi Rev Kit

[NyCowboy87]

Selling the hi rev kit I had in my engine. Springs might have 4k miles on them. They are $700+ new, make me an offer on them as they are doing me no good now and will need something better for when it goes back together. I need the money otherwise Id hang on to them and find a use for them.

 

[NyCowboy87]

Anyone? Im not looking to get anywhere close to what they are new so make me some offers.

in that case.....

 

[NyCowboy87]

Haha maybe if it were another brand.

What load pressure are these springs rated? Compared to 910's?

 

[NyCowboy87]

No idea, but I do know they are heavier than 910's. I was running 125psi of boost at 4-4500rpm and a cam without the valves floating.

 

[Magnum PD]

damn. are the keepers and turners stock? Any shims?

 

[NyCowboy87]

No they came with new everything and no shims are in them.

Is that all it is? Springs? I'm not real sure what all would be included with it. It is for 7.3's right?

 

[Magnum PD]

I think WOP sells a high rev spring kit for about $450.

Yes just the springs and all the keepers etc.

They could, Im not sure though never done buisness with them. If your thinking about price Id like $325 out of these. That is shipping included.

Cant you get 910s for like 100 bucks? What is so much better about these that they cost 4x as much?

If one takes the time to do some research, they are different springs. Different seat pressures, different price.

 

[Magnum PD]

I'll keep you in mind.

NY, dont these require some head work to run? It is a good deal either way for somebody that already has their heads off. I do have to wonder how many rpms and what spring you are thinking of going with to warrant selling these?

Alright I would be willing to work a little more on price too.

Not sure Ill call hypermax tomorrow, the heads and engine were already assembled when I bought it so I cant say for sure. Its going to be a whole different setup when it goes back together and it will need a lot stiffer spring.

Askin was my research.

 

[NyCowboy87]

Alright called hypermax today, the head has to be machined around the spring seat area, no big deal I had this done on another set of heads on my old engine. You can even buy a tool and fixture and do it yourself.

 

[Magnum PD]

Would like to see the tool
