AdamB Posted July 14, 2013 Share Posted July 14, 2013 (edited) Like I said, its the first problem I've actually heard of of the Pec rods, although I have heard from quite a few people that their quality control is lacking somewhat. I wouldn't let it be enough to put anyone off buying their products, as they have had a number of happy customers. Although I agree with Phil, if you want the best its Pauter all the way, unless you fancy spending quite a bit on some custom Carillo's. Although other brands have been proved time and time again. All down to preference really at the end of the day, have heard scat/Pec are a bit of a pain to balance. Edited July 14, 2013 by AdamB Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 do i need to have my block notched for any forged rods then? Quote Link to post Share on other sites
AdamB Posted July 14, 2013 Share Posted July 14, 2013 Scat you do, bit hit and miss with Pec from what I've read. Pauter you don't. Quote Link to post Share on other sites
abbott Posted July 14, 2013 Share Posted July 14, 2013 Dont think you can say a bad thing about pec rods ive had 4 engines built with these and never had a problem. TIm should call PEC and question the problem as i spoke to the owner and hes never had anyone question these or had this problem on these rods. Quote Link to post Share on other sites
Phil Posted July 14, 2013 Share Posted July 14, 2013 do i need to have my block notched for any forged rods then? adam has answered this i know, only thing id add is that notching the block is very simple job you can do yourself once you get your block back from the machine shop/engineer, therefore costs nothing and only takes an evening of time. investing abit of time into your build yourself will be enjoyable too.

abbott Posted July 14, 2013 Share Posted July 14, 2013 did you have to notch your block for any of these builds with these rods? Every block needed to be notched not a major thing to do like phil and adam said its somthing you can do your self and just a couple hours work if you take your time.

mikey4410 Posted July 14, 2013 Share Posted July 14, 2013 Notchings very easy i would say.took me no time at all and only basic tools are nessecary. Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 is there a how to or anything someone could put up please? Quote Link to post Share on other sites
AdamB Posted July 14, 2013 Share Posted July 14, 2013 You'll know exactly what to do when you fit the rods to the crank and rotate it. You can then judge how much material needs to be taken off the bottom of the cylinder. Quote Link to post Share on other sites

Phil Posted July 14, 2013 Share Posted July 14, 2013 Only thing that's ever bothered me is expansion rates, or is it minimal? minimal, pistons once upon a time had high silicone content (7%) but most big brands now dont. i dont think that was ever an issue with rods, also you arent dealing with tight tolerances at all when notching a block or at least that wouldnt be a sensible aim to have.

TurboTobz Posted July 14, 2013 Share Posted July 14, 2013 Just wondered, hmm I suppose it's something that'd become clearer when you have done it and can see it, what sort of size would the notch be out of curiosity any ideas? Quote Link to post Share on other sites
Taggy Posted July 14, 2013 Share Posted July 14, 2013 been using them for nearly a year now no problems Quote Link to post Share on other sites
Bean Posted July 14, 2013 Share Posted July 14, 2013 pec rods in my 5e, and the block was "notched" Quote Link to post Share on other sites
rinseep82 Posted July 14, 2013 Share Posted July 14, 2013 When I put the pec rods in my block try cleared no problem with no notching Quote Link to post Share on other sites
Browner Posted July 14, 2013 Share Posted July 14, 2013 I run PEC Conrods in my forged 5e. I'm running 383bhp with nitrous with no issues at all and plan on running more power on them very soon ;) Quote Link to post Share on other sites
AdamB Posted July 14, 2013 Share Posted July 14, 2013 minimal, pistons once upon a time had high silicone content (7%) but most big brands now dont. Phil This is true, but the Wossner pistons still use the highest silicone content out of all the pistons I've ever seen for the E series engines. Just wondered, hmm I suppose it's something that'd become clearer when you have done it and can see it, what sort of size would the notch be out of curiosity any ideas? A couple mm depth will be plenty, but obviously its easier to judge when its there infront of you. Expansion rates are very minimal, although you do have to remember that the higher the rev limit, the more the rod stretches. Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 well im not going to be running extreme power (not yet ;) ) so im sure theyll be alright, im looking forward to it Quote Link to post Share on other sites
H_D Posted July 15, 2013 Share Posted July 15, 2013 I have used pec rods on both of my forged engines and my old engine is still going strong I was running 1.8 bar of boost on it. Quote Link to post Share on other sites
Azz Posted July 15, 2013 Share Posted July 15, 2013 I have pec rods in my forged build so can't complain as of yet ! Quote Link to post Share on other sites
EPnick22 Posted July 15, 2013 Author Share Posted July 15, 2013 sounds good guys! i may be buying some 2nd hand wiseco pistons and scat rods, 6 months old apparently, think its worth it? havnt negotiated a price yet but what's the wear like on these? Quote Link to post Share on other sites
AdamB Posted July 15, 2013 Share Posted July 15, 2013 You'll be best off getting new rings for the pistons mate. Quote Link to post Share on other sites
EPnick22 Posted July 15, 2013 Author Share Posted July 15, 2013 thats fine i was already aware of that but i was talking about the wear of the piston and rod itself, what do ya reckon? Quote Link to post Share on other sites
AdamB Posted July 15, 2013 Share Posted July 15, 2013 There shouldn't be any wear on the piston. Just check the rod ends and make sure they are not scored or marked Quote Link to post Share on other sites
