pistion choice?

[dantheman]

cant agree theyre all the same quality, for starters the skirts on the wiseco are thicker than the ross, and its lower comp, so imo its better than the ross. also the gudgeon pins are pressed fit on some and some are are held in by circlips, so could argue which is better with that aswell

You have built 50 Engines???????????

where in my paragraph did u see the word built?

dan this is what ross had to say about this piston skirt

Our pistons also have a specially designed and CNC diamond finish skirt profile to allow tighter piston to wall clearance. All ROSS Racing Pistons feature double forced pin oilers, split radius oil returns and gas accumulator grooved second ring lands at no additional charge.

and about the compression ratio.......if u order low compression u will get low compression

if u order stock compression u will get stock compression

its not that they make all flat top for a reason...what u order is what you get sir

its all about personal experiences at the end of the day...
and in my experiences Ross are wank. lol
I would put them at the bottom of the list.
Definately go for JE if you can afford them, if not wiseco.

 

[Nwimie]

interesting discussion :]

Provide some actual constructive criticism, and people may actually not just ignore what you said

oh yeah i FORGOT U BLEW 2 ENGINES...AND U BLAMED UR tuner isnt that right?

have u used JE OR WISECO?

my tuner?? lol is that what you call him..?
Sam id prefer you to keep your mouth closed on this one thanks...it was one of your shit headgaskets that contributed to the problem anyway. and the 3month wait for parts. Dont get all arsey just because you sell Ross pistons and dont want people going elsewhere.
Those Ross pistons lasted a week before the skirts shrank on them, yes that probably was down to running on a base map....but even running the engine in on very little boost i wouldnt expect that.
That is why i dont prefer Ross over the others..
Good enough for you Riko?

that is interesting thread :rockon:

ok so from experiance.. the big power gt's glanza's here use ARias pistons & compared to all the other brands they are superb, have the highest tollerances & the most suitable silicone content compared to other brands..

as for me iv been using ross for a few years now, so have many of maltese tuners, in fact they are one of the prefared brands.. if u have a look around ull notice that the 1st pistons to go are wiseco, iv seen 3 cases of wiseco pistons going around the pins//ringland area & it was not a result of bad tuning or bad clearances, the reason is simple they are made of paper..

ross having a flat top is not really flat anyways, if u look at the oem pistons & measure them ull find they have a 2cc drop, ross offer 2 piston types (well for us at least) the oem ones with a 2cc drop & the ones which are low comp with a 10cc drop.. now u also have to take into account the valve pocket clearance... Dave i dont know who ur odering ur ross pistons from but they are definately not flat top.. from the stock sets iv seen iv never come across a flat topped ross piston.. maybe they have changed design.. well in that case im unaware..

now if u read the ross spec sheet they supply 2 sets of clearance settings, as toby said one of them is for nitros applications, HOWEVER the normal ring clearance for ross is 4 thou.. sure not much but it makes a difference.. the rattling is not only cause of the clearance but cause of the silicone content in the piston.. it depends on the composition of the piston..

personally id NEVER use wiseco pistons, iv had to many friends use them with loads of bad news.. (not on starlets).. IMHO JE are waay overpriced for what u get.. the choice is simple.. u want undistingushable quality go for ARIAS... u want overall good, realiable & inexpensive u go for ROSS..

btw, i havent heard anybody talk about ceramic coating & friction reducer coatings.. also something very important to consider when buying a set of pistons.. all are available from most piston brands.. sure it costs more but either do it right or dont at all imho..

[AdDaMan]

only problem is Kon, Arias arent as freely available over here as they are in malta


(and it wasnt one of the options!)

well if i recall adam..u were the one who told me ur tuner messed u up twice...just recalling what u said and u said he was good for notin and i asked u why and u explained to me.........of course i have to back up what i sell..WONT YOU?

shit headgaskets?
i pardon you........ur same tuner which i will not mention who built ur engine bought 6 headgaskets from me so if ur tune was shit expect ur gasket to go..

i ONLY sold 100 gaskets with no complaints so if u want to call it shit then thats ur opinion.......

3 mth wait for parts werent my fault....but no one is talking about time here..we are discussing pistons..

anyhow i dont kno what else to say other than its members choice on what they want to buy.....

 

[AdDaMan]

yes i know he bought six gaskets from you thats the reason i had one fitted instead of a Zep/Cruise, which i asked for. the gaskets themselves arent too bad but is far to thin for my apllication which i told him. And i repeat..he is not a 'Tuner' just a mechanic.
we all learn from our mistakes dont we....
anyway....back on topic....this thread is about pistons and i have given my opinions.

I don't supply them as they all seem to come through flat top now, all the sets I have seen have been bought on here

hmm, I'm not expert in aftermarket pistons, as the only forgies I have been using were installed from manufactory

I posted a long review I found on previous forum a year ago. If I remember well, they were detailing the rattle fact and explaining why it was doing so. apparently they use silicon in those forgies. the less you have of this silicon, the strongest your piston will be, but will expand more when hot. So forgies that rattle when cold are pistons with less silicon and are the strongest ones.

car factory forged piston like honda type R and subaru STI use a lot of silicone so they remain street usable to anyone.
ROSS and JE use a little of that silicon, so their pistons rattle more than others but are stronger.
Wiseco are just in between, they use less silicon than car manufatory forgies, but more than ROSS and JE. that would result with a bit less rattle than ROSS & JE
To cut it short. I would think wiseco are a "bit better" for street tuning. ROSS and JE would be a "bit better" for Racetrack and pod project. even if any brand could be use for any application...

Now, I have never owned and compared aftermarket forgies myself. this is just my thought from readings I have done in the past

cheers guys

 

[dantheman]

i know people who have used ross pistons and had the same problem i did with the skirts cracking, and a few of my mates are running wiseco pistons on pulsars at high boost for a couple of years without probs.

theres obviosuly going to be lots of people who have had bad experiences with different brands and then obviously they are ganna slate them, when there are alot of factors in how pistons fail,not just down to the piston itself.. think we can only go by peoples experiences on this one

but i can tell you the skirts are a fair bit thicker on the wiseco than the ross's, which is a good idea. couldnt comment on the quality of materials used though..

 

[crf_throtlejocky]

nice one lads makin good readin its all down to the way its built and tuned boost ect i just want as much life as possible .i use wesco pistion in my motocrosser so think ill give them ago just cause its a known brand and they r cheap

i was going to say about wesco making good motox pistons but im not sure about the car ones . i would go for ross if it was me doing it
