Mine are the original springs as far as i,m aware and my engine builder has tested them and all seems ok , i was just wondering whislt i,m spending the money on the rest of the parts should i replace them for new ones . Its apart at the moment and i,m already getting the what ifs lol .Standard engine only going to be 350 power max for the road .
.Any thoughts and experiences ?

Cheers
Mike

 

leave them in if your only looking at about 350bhp

 

As above leave them standard

 

I,d only replace with standard items anyway its just that mine have done 100k .
I dont want a failure down the line as its the 2nd build on same engine and getting fed up with them lol.
Thanks for the advise guys still not sure tho.
I,ll check your prices Matt too

many thanks

 

Roughly, whats the max bhp standard valve springs can take?

 

would it not be worth while going for a double set up as they make the engine rev much nicer

regardless of power going for

its a little bit like the arp kit over standard argument
i know the standard bolts are more than up to it but are still old
thing new fresh springs can only be a good thing

 

Standard cams and engine so the standard items are fine its a question of age or fatigue . As i said mine have been tested and seem fine but i was thinking of replacing for new unused instead of 100k ones lol. I think i,ve made my mind up hehe

 

Ive got a set that have only covered 15000 miles and are only a few years old if they are any good to you ?
