Dastek piggyback

Ive just fit my dastek into the pulsar

its come out of a pulsar that only had a hks mushroom filter on.
Mine is the same setup minus the mushroom filter.
Its mapped for 1.2bar so im going to turn my boost upto 1.2bar and stick it on the rollers to have the fueling checked

good luck stu, wont tell u what mine was inadvertantly running with a kinked boost pipe today at the sprint day but it peaked very high for a standard lump and tubby

lol i can guess mate, i did the same before and saw 1.4bar lol

mine peaked at 1.7bar luckily i noticed it and stopped before it cooked the tubby and motor

Is 1.2 bar safe on standard pistons? And at what point would forged pistons be needed

Yes, there's people running upto and known to run over 400bhp on standard internals.
The time to change to forged is when the engine gives up and you need a rebuild!

If it ain't broke, don't fix it

1.2bar is fine as long as the furling is ok!
