Anyone using Jesel double roller followers?

[thump_rrr]

I've seen nearly every aftermarket part used on S197's except these.
I was wondering if anyone here has tried them?
At $115 each retail they're quite steep though.

i saw those in a mag a while back....they're suppose to be good for quite a few ponies iirc. probably not any more expensive than a quality set of long tubes. that gets me to thinking...these you can install yourself assuming you have the tools and can save a fair amount of labor compared to installing lt's...have you seen any performance numbers on these? this might be a viable option for my next mod rather than long tubes. if they're worth only a couple horsepower, than it wouldn't be worth it. but if they gain 20 t0 30...you're talking long tube performance gains and an installation i can do myself....

If you are not running very high revs I wouldn't look into that.

For $2,760 they must be one hell of a set of longtubes.
I have removed the factory rockers on Rons motor and it's not that complicated using the Ford tool.

your looking at 25-35 rearwheel HP , so the article says because of the flexing of the stock followers !

Just go to to Muscle mustangs and fast fords web site , on the search type in Jesel 2v or Jesel 4v it will bring the article up (good read )

I really think there talking about 8k and 9k rpm cars to get this power !

Pete,
We used them twice when they first came out. Once on a four valve road race engine and one two valve n/a high rpm deal. They were worth 20 hp or so in both applications. Could be worth more with the better valves we have available today like the hollow stem stuff. Really will help with higher valve spring pressures and/or boost pressure.

Thanks,

It just seems like there are guys out there that are looking for that last little bit and I was surprised not to have seen them used here upto now.

It is the price. That stuff is high dollar. Add in the additional cost of the solid lash adjusters and you're easily over $3000 on a three valve. Just plain old "sticker shock".

just like the article said (lol)

They don't look much different the regular roller rockers. But if you can get more...
