Are they worth changing and whats the advantages?

or are the standard ones just as good

Thanks

 

they are if u a revving it past 6k, put that depends on rest of engine.

 

Hi rick

well ive taken you advice and ive got a MF2 driver 5th injector going on jan 5th and all remapped and fitted by power eneineering also on monday im ordering a pro alloy BIG intercooler so hopefully all that will make a difference

also later on im gonna get steel rods , MLS headgasket , big valve head and while all thats off I was maybe gonna put new cam and followers in (depending on condition) and just wondered what these would be like

 

heres the Spec if you cant remember

1600cvh
low compression mahle pistons
piper T2 cam
S1 ported inlet manifold
Lightend and balanced bottem end
pace intercooler (normal sized one)
EMC fuel-air mods
mongoose stainless exhaust
hybrid turbo boosting 23psi ( i think this is a stage 3)
-31 actuator
ahmed bajoo mapped engine managment
AP paddle clutch
baileys dump valve
Samco hoses
K+N panel filter
piper vernier pulleys

 

So, what exactly is the difference between an Anti-Pump lifter and a standard one then?? Has anyone ever cut one in half??

 

yeah id like to know this,because there about Ł100 for a set and wanna know if its worth it

 

the difference is a softer spring inside the normal followers have fairly strong springs in, so if you get valve bounce the lifters take up the extra space right away. anti pump ones with softer springs are much slower to react so dont take up the extra space (not in the amount of time you would sensibly be in that situation at least! )
thats how i understand it anyway!
remember kids, always change cams and followers together, if you want the parts to last longer than a few k anyway! ( 4k im my case ) ah well important lesson learned!

 

I have a brand new set at home unused. When I swapped to a high lift cam and uppedthe rev limit to 7200rpm I swapped to a set of these, didnt have any problems.

 

run anti-pump lifers in mine, never had a problem, Im also using double valve springs in my big valve head!

As stated before there made for high reving egines. Solid lifters is the more extreme way to go!

Would be intesting to chop one up thou! anybody got any old ones, and angle grinder???

 

Its just another one of those things that we are sold not really knowing if they are any different to standard as they look identical externally.

 

Christian, remember when we replaced mine - could see no difference at ALL

Was better to be safe than sorry at the time though

btw, how the mapping come along?
