new engine for my fiesta will hopfully be 130 horses

[5hane]

went to the NSRA auto jumble today at arena essex...

 

 

picked up these

 

 

 

set of titan high lift full roller rockers

 

although now, i proably wont be able to use me rocker cover so i might get something macheined up so i can still use the top half

 

[Fiesta Steve]

Why can't you use the rockers with the piper box ?

there too big so i thought about getting the sides macheind, but then i would also need a 50thou plate to go under the rocker cover/ posts so then it would be the same height as the steel posts, and the shaft is a lil bit bigger on the rollers

 

 

i spoke to me next door neighbour (who does enginnering) and he recons it would be much easyer to start from scratch with the bottom half, rather than modify the piper peice. Also if it were modified, it couldnt be used with standard rockers if i were to sell it

 

i dont know, ill sort something later, its not a main component so it might have to wait for a while

Well, you won't see the roller rockers so no one will know they are even fitted.

 

Whereas the Piper kit does look cool when you open the bonnet

i 100% understand what you mean and i really wanna use it

 

but the cover has no real gain, where as the rockers do

 

 

becides, im hopefully gonna have another peice made up so i can run both (basically the outline, and just the 8 bolts)

[Stu_B]

Got a new rocker cover for mine. Makes a huge difference to the look of the engine bay. Just need to sort out a breather or run a pipe to my catch tank.

 

 

[Toby]

Lovely looking pre-cross you have there Stu,

 

It looks like your front carb is spitting a bit.

[5hane]

With alot of elbow grease....

 

 

 

 

 

[5hane]

ps. did anyone else see that other piper cam cover on ebay ?? i think its been taken down

[banarama]

very nicely put together

[Toby]

5hane what centralises the rockers? You wouldn't want them rubbing on the rocker posts I wouldn't have thought.

[5hane]

Currently nothing, there rubbing, although i was thinking of getting a few shims (copper? or steel ??) to put between the rockers and the posts ? just a few thou thick

 

 

Also, i think you would be the man to ask, whats the reasoning in having +50 rocker posts??

 

 

Cheers

I don't like the idea of ally rubbing on ally. I'm not sure what takes the side thrust on a normal roller rocker set up - I'll have to look!

 

 

The added height of the post supposedly corrects for the higher lift of the cam (if you install a high lift one!). The thing is though, all cams are ground on different base circles, if the blocks been decked, various push rod length etc will all have an effect if you're looking for the last 1 or 2 hp!

[Fiesta Steve]

Good effort getting them in If your using a high ratio rocker your not going to want much cam lift.

on the standard setup, the rollers run against the steel posts, and some steel spacers (instead of standard springs)

 

 

ohh right, so do you think its worth getting a laser cut shim made to go under the rocker cover 50 thou thick, in theory making them +50 rocker posts?

[Toby]

Possibly true, but doesn't resolve whether there is a requirement for +50 posts or not....

 

Some measuring will be required me thinks

was thinking of going for a kent 254 cam, do you think a 244 would be better then ??

 

wouldnt that give a better tickover aswell??

Sounds technical, I'll let you resolve that one
