Wiseco Pistons.

DCC runs standard rods and pistons and makes 175...

[welshpug 1,657]

Why do you say this?

 

on the observation of an engine builder that has seen them fail.

 

plus they don't look great when you compare them to decent rods, cheap for a reason!

[Matteo 17 1 Cars]

My mate Roberto has recently thrown a standard rod with 165 hp... (not due to lack of lubrication)

good effort!

[dcc 855]

Worth pointing out mine spent most of its life getting close to the 7700 limiter

 

I have been trying to kill the engine to give me a reason to get a sandy built xu or ew, the bloody thing wont die.

Surely just middle of the road? They don't look like cheap chinese rods and they don't look like a Carrillo. However, when you consider the price of reconditioning a set of standard rods, bushing them and adding quality rod bolts, aren't they reasonable value?

Hey Mei, that sounds a bit like a 'I know a bloke who once told me...' comment!

I thought you might have had some actual experience with PEC rods. I guess not. A quick Google search shows plenty of high powered including forced induction engines successfully using them.

Like most things there's a budget to be considered but I'd be happy for you to stump up the price difference for some Carillo, Fardon or Robson rods though.

[rallyeash 155]

Ok PEC aren't going to be the best, but I would consider a step up from a standard. Seen lots of people chuck standard rods through the block. I'd be surprised if the above pictures would of happened with a PEC rod fitted. Would of also been cheaper for the above member to of spent out on rods, will now cost him more in the long run.

That bloke was Sandy, so go ask him and he will probably say use modified standard rods or carillo.

 

 

I recall one of his very well performing "mild fast road" spec TU engines, used in a race car, 1600 ish, makes high 190's, perfectly reliable over two seasons afaik,on modified standard rods.

 

As mentioned, DCC's 175 bhp XU9 was built many years ago and only has an uprated vaveltrain and 300 degree cam, its 100% factory peugeot bits elsewhere, no race components whatsoever, I know this as I rebuilt the engine myself (not that it needed a rebuild, we thought it had spun a big end but turned out someone had forgotten to torque up the flywheel bolts....) full set of std bearings went back in and its had 10k (miles) of death since.

 

 

All those rods thrown through blocks wont have been purely the fault of the rod, or the rod bolts, it'll be bearing failure of some sort.

 

All the XU and XUD use the same bolts, so the 7450 rpm that the XU10J4RS goes to is well within the capability of the XU9JA rod bolt, more expensive bolts just give you a higher margin if you take it to those revs more regularly.

no Jeff, its a pretty well known fact.

 

PEC have a design flaw which shows a reduction in material between the bolt head surface and the bearing surface. not only this the angle is very sharp (with no taper and holds minimal strength. a poorly designed, cheap, and frankly crap rod for a market of people who think they are getting a better deal (not quite the case in the long run).

 

You can see how poor the design is here - look at where all the stress & strain is going to be focussed!

 

Time bomb!

 

[dcc 855]

and the difference with a well designed rod

 

[petert 586]

I can see your point, but does anyone on here actually have any experience with one letting go in an XU engine? Or is just urban myth?

[welshpug 1,657]

They're probably too busy building and refreshing engines and mapping to post on forums

I don't work in the PEC factory, but the manufacturer states they are made in Sweden and designed in UK.

You will easily check that Roberto didn't spin the bearing but simply gave up the cap (not even the bolt ! )

[Kane 34]

What is the typical cost difference between custom carillo rods vs. PEC? And just to throw another spanner in the works how do Robson rods compare in quality and price to the above?

[JeffR 51]

I was quoted £500.00 per set (of 4) + delivery for Robson rods. When I enquired mid January they were running a promotion at that price.

 

Haven't got a price for Carrillo rods.

[Miles 331 1 Cars]

I always use either Saenz rods or Arrow rods, not cheap but never had any problems with any of them or the biggest thing is product support

[JeffR 51]

I got zero support from Arrow when I had an issue with their buckets for solid lifters. Couldn't even get a reply from their Technical Support Dept in the UK.

[welshpug 1,657]

pec rods are £485 plus postage, wossner rods £660 plus post.

 

IIRC Farndon are £550, Carillo circa £600.

[JeffR 51]

I was quoted £395 for PEC from Pug1Off, £405 from PEC. Aren't Farndon & Robson 2 brands from the same company?

[welshpug 1,657]

pec is £405 plus vat (20%)

 

no idea of the robson/farndon thing but they do indeed appear to use the same address, two different websites!

 

Robson say £500 plus vat on their site.

The Pauter rods are very good, but expensive. Paid about 800£ for my custom set if I remember correctly.
