ky_uk 304 Posted November 18, 2015 Author Report Share Posted November 18, 2015 very true! burnt a hole through my wallet lol. but, i highly recommend the water pump, excellent quality and you can feel the difference in weight against the OE one.looking forward to this coming together though. nice one! I am just hoping I can have it ready before GTI fest! Link to post Share on other sites
RBPE 198 Posted November 18, 2015 Report Share Posted November 18, 2015 Just had the definitive answer from Vince at Stealth racing, the standard 12V VR6 crank is stronger than the R32 crank. Thought they were both 4130 drop forgings so same properties but different physical exertions due to different bore/stroke? Link to post Share on other sites

RBPE 198 Posted November 20, 2015 Report Share Posted November 20, 2015 (edited) You know more than me I just was brainstorming and asked Vince and he said stick with the standard crank Due to the VR design you get various stresses which can be increased using different sized components,so really sticking as close to factory development is usually a good idea but displacement, revs and boost are power increasing factors so are often done but you have to think about the additional stress such changes can bring. The VR's love boost and handle them well, just need to fine tune, strengthen and hone the reciprocating masses! As for material,I looked into it a while back so can't quite remember but it was something like 4130 material was used as I was comparing it to the common 4340 specs of aftermarket parts, being an R car though they might have upgraded over most oem? Doubt it though for only 250hp! Edited November 20, 2015 by RBPE Link to post Share on other sites

RBPE 198 Posted November 22, 2015 Report Share Posted November 22, 2015 So what is your opinion on the standard crank running over 500bhp ? Yeah stock crank can handle plenty if done properly, you're doing the right thing in getting it all properly checked before it's rebuilt, oem material always seem to have budgetary constraints, but places/people like x-parts/donkey tec/turbo impression show you what can be done. Aftermarket engineering can get complex if you want to get technical, there's loads of funky new alloys about too nowadays and various things to consider really, was looking at an interesting report a couple of years ago regarding some new alu alloy for pistons and it was interesting that the 2618 pistons, the forged "rattly" ones due to expansion properties because of their superior strength/max heat resilience properties over the 4032 alloys, actually were affected by sustained temp's more. Went into detail on how the cycles were to replicate typical heat cycles of a daily engine by this company etc and how their new "R5" alloy, or whatever it was called, did this in the test which obviously trounced them both!Point is, there's huge depth you can go into regarding proper engineering/tuning so you don't need to go overboard, a bad map could rip any new forged build to shreds and most oem parts like cranks will be the same to some degree due to mass production. Not sure you mentioned it but you may also want to consider; http://www.uspmotorsports.com/Engine/Pulleys/Fluidampr-Engine-Damper-VR6.html ky_uk 1 Link to post Share on other sites

RBPE 198 Posted November 26, 2015 Report Share Posted November 26, 2015 I have been looking into pulleys I have a separate thread about it but everyone swears blind the stock is best. Depends if you're having it all balanced by the machine shop and the weight changes due to rods etc I suppose. Harmonics are a massive part of proper engine tuning but obviously there's a number of factors like if you are going to extend the rev range where they can get worse, oem single or dual mass and changes etc - I would use one on a decent/expensive build though.
