DELCOS NEW RIDE

[delcowizzid]

right the hunt for 10's in the VB has begun today started fitting the new 1.65:1 yellow terra shaft mounted adjustable roller rockers but to fit them we need to lift the rocker covers for clearance so begins the epic kiwi battle against alluminium in the trusty shed :biggrin:

prepare the precision milling machine seen here mid use

mid alloy battle fallen soldiers everywhere and i mean everywhere but we are winning LOL

finish drilling all 107 holes with said precision mill and attack with 1mm cutoff wheel

after a number of hours with the above tools and grinder and flapper disks you now have a spacer ready to polish but only after drilling yet another 6 holes LOL few only one more spacer to make :frown:

bit of a polish

not looking forward to the second one

you can actually buy the aftermarket alloy tappet covers which come with those spacers

[delcowizzid]

yes but they look yucky as hell LOL and cost money haha weve spent around $4000 on a whole car and turbo setup would be nice to go 10's on the cheap and we only buy parts that make HP LOL

[delcowizzid]

ported heads next they reckon just a good bowl job and removal of casting dags can yeild 30-40% more flow thats a lot more power right there

roller rockers are a waste of money, fuck all gain for the $$$

[delcowizzid]

soon to find out they did something it idles way different when we started it without covers on

[Holden202T]

wouldn't be the breather hose on the tappet covers changing things ?

Solid effort mate, second one will take a fraction of the time - why buy stuff when you can make it - cheap third world labour - nah sweatshop in Wellington never mind the time how many drinks did it take

Rockers might make a SLIGHT difference as much from the lifter preloads being properly set up as anything else.

[delcowizzid]

lots of drinks mate lots of drinks LOL. rockers should gain us 1.2mm of valve lift bringing us up into the sweet spot at 0.495" lift or 12.57mm i can tell you there isnt much room left before coil bind on the springs just hope they havnt made the ramp rate of the cam too hard out with the extra ratio.should hopefully eliminate any rocker flex if we had any a head cam and inlet 350 chev can gain 17hp with roller rockers over stock pressed steel rockers with the same ratio and 22-27hp with 1.65 compared to 1.5:1 so we may just gain a little when all said and done find out tomorrow might even spool the turbo differently

That'd be because the stockers are notoriously innacurate with what the 'actual' ratio is.

Yeah mate i thought it looked like thirsty work
