Thread was posted the other day about people using forged con rods from China and people were going to buy them.

EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 but how would anyone even be able to create that kinda damage lol?! im going to be running my stock ct9 for a while Quote Link to post Share on other sites
mikey4410 Posted July 14, 2013 Share Posted July 14, 2013 massive huge amount of overboosting,i did the exact same to a standard rod years ago.i had a split in vacuum line to wastegate on a td04 setup.i was so lucky the rod bent and didnt snap Quote Link to post Share on other sites
AdamB Posted July 14, 2013 Share Posted July 14, 2013 That engine was stripped by Tim @TBdevelopments, here's what he had to say about it : "no this was the worst one of 4 after a major failure. All 4 conrods had very slight bends in them only running slightly above stock power. Because of the bends it caused the bearing to overload on 1 side leading to bearing failure. This one was the first one to majorly fail where the bearing grabbed, spun then welding itself to the crank causing that huge bend and then pushing itself out the side of the engine block casing.all 4 bearings were in a state of failure, but this one was the first to grab and then the resulting damage was caused from that event. so that bend wasn't caused from normal operation. but the initial bends in all 4 rods were down to just poor construction which lead to this" Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 okay so im definitely not getting them lol Quote Link to post Share on other sites
rinseep82 Posted July 14, 2013 Share Posted July 14, 2013 Nothing wrong with pec rods mate any product could come faulty and if every rod had a bend in them it should have been picked up on before they even went into the engine surly it would have been noticed during balencing and I think pec rods are made by cosworth my pec rods came is cosworth stamped boxes Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 how long you been running them for? Quote Link to post Share on other sites
rinseep82 Posted July 14, 2013 Share Posted July 14, 2013 I never ran them buddy sold the engine before I even turned the key the chap that baught it hasent had any problems tho as far as I'm aware Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 ah right, any opinions from other people who have ran them or seen them run? Quote Link to post Share on other sites
rinseep82 Posted July 14, 2013 Share Posted July 14, 2013 (edited) Well put it this way Dave at tm-development advised me to use em and dave knew what he was talking about Edited July 14, 2013 by rinseep82 Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 thats fair enough just interested in few other peoples inputs maybe from past experience or anything Quote Link to post Share on other sites
mikey4410 Posted July 14, 2013 Share Posted July 14, 2013 when i bananaerd my standard rod as i said above i bought some pec rods and wossner pistons from dave personally (went up to hi place) he obviously thought alot of them as thats what he recommended Quote Link to post Share on other sites
rinseep82 Posted July 14, 2013 Share Posted July 14, 2013 You won't have to notch your block if you use those either because there just a bit thinner than scat rods so don't catch the bore Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 after seeing that picture its scaring me haha how much boost is over boosting though? i run a bar boost on ct9, doesnt creep Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 thats interesting, how much wider are they then if they catch? surely they should be designed so they dont? O_o Quote Link to post Share on other sites
rinseep82 Posted July 14, 2013 Share Posted July 14, 2013 (edited) Don't let that pic scare you mate it could happen to any rod or piston and no they aren't you have to get your block notched to fit scat rods and its only very small difference Edited July 14, 2013 by rinseep82 Quote Link to post Share on other sites
EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 i guess so, I just cant afford to have a set of rods go on me Im going to be skint just buying the bits, lucky im rebuilding the engine myself, got all the machine work covered where i have an engineering workshop in my garage so my budget is a little tight, i didnt plan on going forged, only due to my pistons going bye bye Quote Link to post Share on other sites
Fozzie Posted July 14, 2013 Share Posted July 14, 2013 Tbf, forged components are obviously a great deal stronger than stock, but they're not indestructible. Under the wrong conditions any component will eventually die.Taggy melted the first set of forged pisons that went in his EP70 (not sure if they got to the bottom of the cause).I guess the point is that a couple of bad pictures shouldn't scare you as it could happen to any part and it's pretty rare to see from any of the 'established' manufacturers.

EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 you make a good point dude, I found a package deal for wossner pistons with the PEC rods for fairly cheap so i was leaning more over to that direction Quote Link to post Share on other sites
Phil Posted July 14, 2013 Share Posted July 14, 2013 if its about quality control etc - buy pauter imo there 4e i-section has been the top rod in the market for years. if you want the best cost like i would need id be buying maxspeedingrods from them directly. even offer to buy a few sets to get the price down them sell them on.

EPnick22 Posted July 14, 2013 Author Share Posted July 14, 2013 i would more into the maxspeeding rods but only way of getting them is buy posting overseas, the money id pay on import duty and other fees will probably be half the amount i pay for the rods lol!!

Idrees Posted July 14, 2013 Share Posted July 14, 2013 Has anyone had 4E/5E rods fail from PEC? I don't see a problem with them. I'm using them in my 5E build, along with several customers. Nobody has complained about them to us. Browner uses them and his car is/was running 383bhp. Quote Link to post Share on other sites
mikey4410 Posted July 14, 2013 Share Posted July 14, 2013 pec rods do need block notching,for sure,i had to. Quote Link to post Share on other sites
