My Terrible Experience With Wiseco

[Slippi84]

About 2 years ago there was this company that made manifolds that were notorious for cracking during high boost loads even though they were reputable company that did R&D and all the other good stuff. Some people said they were junk others swore by them. The company put out new style manifolds and fixed the problem as you don't see many cracking anymore and the world continued to spin.....for you noobs or people not in the know that company was Magnus.

Moral of the story just buy the HDs and let the world keep turning.

 

[cuzco]

I use n/t blocks. No filler required.

I was thinking for a motor seeing 40psi+
Do you thing that would be ok?

Ontopic. I checked 2.0L wisecos that I had in a motor for a very short time. Didn't see anything wrong with them but I'll check them better.
The problem I had with them was I had my machine shop press them onto a stock set of rods. And one of the pistons was stiff on the rod and the guy said of would be fine after first warmup. Then after a few miles blue smoke started to come out of the exhaust. One sparkplug had oil on it so I took the engine out and apart, to my surprice the piston bolt had ripped the cylinder wall.

Now I kinda wanna take my current engine apart and check the pistons I have now.

-Just as well for the same or less like Mahle, Arias, or Ross, just how everyone jumped ship to JMF. ! Yes the world does continue to turn but the company at fault loses business and rightfully so, that's how commerce works. True, people will still run Wiseco just not as many. I myself run Magnus manifolds even still but you can't say it didn't tarnish the reputation or sales.

However, that could be construed as a bad comparison as a whole. Where as no problems have been recorded with the new Magnus manifolds, there were (possibly are) many issues with the Wiseco HDs even yet. Hmmm, I guess its all on the persons own gut feeling. Just don't purchase a set of HDs unless you have a patient and VERY capable machinist or else you are in a world of hurt. You'd save even more money than simply buying a different piston due to the money you'll save during the machining process...

Eh, doing a half-filled block at least wouldn't be a bad idea, but many have had success using the stock block. If its a race car and not a DD, I say do a 1/2 fill.

Boost pressure does not dictate how much a piston/head gasket will hold, it's cylinder pressure.

I made 621 at 29/30 psi on straight 93 octane no meth nothing. My car was hitting 37psi on straight 93 one night because of load on the car(3 people in it). Yes this is on standard wiesco pistons that are now 6 years old in a 2.4. Prop About 25k on them.
2 years at 400 hp 2 years at 500 1 yeAr how it is now. I'm sure at 621 it's close to or over 700hp at the flywheel.

I retuned the car since then and wouldn't doubt mid 600s on pump. I'm current in the process of swapping the setup into a auto car because I'm tired of sheering off gears in glorified factory 5spds and going high 10s with crappy 60fts

Alex from dogbox made alittle over 800 to the wheels in the laser on standard wiescos and eagle h beams and eventually it snapped a rod bolt. Not bad for 9.3 passes 127 in the 1/8th and 1-2 shifts at 10k.

Shit happens. Products have flaws. Machine shops mess up. Drivers mess up.

For what it's worth, i just inspected my wiseco's, and they were fine. This is after a bad alternator leaned me out around 30 psi, and blew fire out from in between the head and block, with a1 toolsteel studs.

oh.. id like see that

 

[GORBS88]

132mph on the wiesco's?

I'd like to hear from anyone having a failure due to the cracking on the skirts.

Many people trap that on STOCK internals so shouldnt be a problem on wiesco's

I dont have any experience with these pistons so i cant say much, but i would like to add that the fact that KNOWONE has had a piston come apart shows me it not a strength issue.
The only reason people know there cracked is from taking the motor apart and finding it.
So for the guys running these pistons and have now gotten themselves worried i would say you dont have much to worry about.

Dont get me wrong it sucks spending money on parts that have this issue, but that piston is NOT going to fail.

You say this based on what? Hear say? Between both shootouts last season Kevin's fwd was the fastest and most consistant and he gave them the nod along with several other big name DSM players who don't get other people to do their work so they obviously know their shit. How can you have a product where so many people who know their shit aprove of be bad? I got it because so many people who DON'T know what their talking about who chime in because they're so pro another company or had a problem with said company before with another product that they assume guess talk out their ass ect.

What part of my post wasn't made clear. Everything being said is "hearsay"

Hell you are going off of what Kevin told you and I was going off of what Jake told me as well as a couple machine shops I was planning to use. Who others chose to believe is up to them. They can use the search functions just as easily as anyone else. All in all, any option mentioned does just fine running the high power the OP is seeking. Its not a matter of which can do the job, its which can do the better job for less.

I say I wouldn't run Wisecos because I simply don't have to. Too many other fish in the sea. If you have bad issues with them, by all means, jump ship. They don't offer some overly superior product to the competition so there is no reason for anyone to have to forgive them, just move on. As I mentioned, that is commerce 101. At the end of the day we all use what we feel is best. OP had some issues with his pistons and its a common problem, thats a FACT. Why people are in here still posting or arguing, I don't know. Just let the OP move on with his decisions.

.

I undertstand this, ask me how I know.

 

[GORBS88]

I don't need to ask you.
I was just wondering why you asked 132mph on those pistons? Thats all.

 

[slowgsr]

Im sorry, I wasn't trying to be rude.

132mph in the 1/4 is fast, and yes, you can do it on the stock engine. However, the guy who went 132mph on the weisco's went 110 in the 1/8, and he says he had shifting issues. So chances are he could have trapped much higher then 132 on the power he was making?

Anyways, its not important. I was just wondering, thats all.

I built an engine with weisco's, im not worried, im just going to push it like I would anything else.

I own wiseco 1400 pistons and have run the regular WIseco pistons in two other cars how is my view hearsay? Have you ever even held a WIseco 1400 piston? Jake is a very established and proven dsmer but he's no Kevin who runs and owns his own company that specializes in making parts for our cars to run better and faster along with the other people that cosign to Wiseco 1400 pistons. So I brought up my personal hands on experience and a established and respected dsm company owner along with countless others who have run them and love them. I'm lost how your unconfirmed machine shop and one racer even though it's Jake compare WTF

 

[Slippi84]

Jose Clavijo "Wiseco 1400 HD's. Just had a car dyno 855 whp with them installed. "
Ron Shearer " Wiseco 1400's are the best piston out right now.

An off the shelf set of Wiseco's with upgraded pins will be absolutely fine for 700hp as well.

Did you read that on the internet somewhere? Myself, Nutter, and I think Kiggly tried to get him to send the parts in to see what actually happened. If I remember correctly he was using Groden rods and nowadays I'd say that was the likely cause as many others have had that happen."

Kevin Kiggly "This is just speculation with no proof. Jake had SOMETHING come apart. I believe there was both a rod and a piston involved and no proof that the piston was the first thing that came apart. I asked him a few times to send me the other damaged parts so I could look for the source, but he never sent anything. His pictures looked to me like he had pistons touching the head in all 4 cylinders. If it was a piston, there would almost guaranteed be cracks in all the others at the failure initiation point.

I ran the same set of 1400HD's all last season with no problems at all piston-related. Sure, I picked up a piston in a million pieces after the car broke a rod. There was crack-growth marks and the primary failure fracture surface on the rod though. The other 3 pistons had no cracks, bad wear, or damage whatsoever."

 

[JOEY A]

Is this a new problem?


I built a motor almost years ago, been in two cars l and has been making 600hp for more those years and still no problems at all

No prob,

I trapped over 132mph in the quarter but only 104mph at the most in the 1/8th. So 110mph in the 1/8th is DEF honkin' right along.

My ONLY concern with this thread is that some of the guys that bought these pistons and haven't installed them or have installed them but haven't run them are going to be abit nervous!
There has been NO proof brought to the table where one of these "cracked" pistons have come apart or 'failed'.
IF you have them, RUN them..

 

[diambo4life]

Not sure if I have posted in here or not but I have the regular Wisecos in my car. My car is raced a lot and it's my DD too. No issues. I bought the Wisecos used too. I had the same type of pistons in my old SB that cracked a cylinder. Pistons were fine and I sold them to somebody else. Sometimes freaky things happen. I just reinspected my cylinder walls yesterday (replacing 5yr old HG) after having not removed the head for almost 3 yrs and there were no cracks in there. Paranoia is for the weak.

If you just removed the head then you wouldn't have seen cracks as they happen on the bottom of the skirts like in the OP's picture. I don't know if they would really cause many issues unless they seen alot of stress past what they are originally built for anyways.

That's not what I said. Re-read my post.

Jake at that moment was on the fore front of what it takes for anyone to run fast times in a street car.. NOT Kevin. You speak of Kevin as if he did any more work to his car than Jake did... This wasn't a matter of Jake VS Kevin either but both cars are so different that I wouldn't bother to compare them. I didn't know you were building an auto, drag only, tubed FWD race car. In all comparisons, Jake's AWD, stock bodied street car presents a better comparison of how something would perform on the street more realistically.


I've held HDs, ran Wisecos in a 2.0 4G, and ran other brands as well.. Have you done any of that to even begin to compare how superior one will be to the other? All I simply stated is that the HDs are not to be put on a pedestal in comparison to any other brand. They have all proven that they would get the job done. It becomes personal preference as to what someone wants to buy and at the end of the day there is no point arguing it.

The FACT of the matter is that there are multiple options out there that all get the job done. My choice not to go back to Wiseco is just that, my own choice. At the end of the day the issues I have heard had only a slight bearing on my decision. I simply had zero reason to go back to them. No grudge, no bias. There's just to many other capable options that are every bit as proven that many use and will continue to do so.


I don't know why any of the arguing started... The OP came in and made a statement about an issue that is KNOWN to have occurred multiple times with many builds. If his experience moves him to no longer use Wisecos, who cares? Its his choice, let him be. He's not missing out on anything moving on to another company so why argue with him about it?

 

[TSIMonsteR]

This thread made me a little nervous about my purchase of used Wiseco stroker pistons.... but I got them in a few days ago, and they look perfect. I think its all about the amount a of piston slap you allow.... its gotta be.

 

[cuzco]

I run the std 2.0 liter wisecos in 9:1 compression and I made 142mph in the 1/4.
Compression test shows even 175psi across. I'm not worried anymore.
I'll change my arp's to L19 and let them see 40psi. Boosted 35-37psi last year.

[cuzco]

Just to keep this updated. My std 9:1 comp wiseco's saw 43psi and I trapped 150mph and a 9.6 pass aswell. I believe I was passed the limit and there was some luck involved
Still have to make a compression test.

Yeah I just gave up trying to tell the naysayers that Wiseco pistons are nothing to worry about because some people just get an idea in their head and no matter what you show them or bring to the table that idea will always be there. Oh well I don't get paid by Wiseco to say this stuff just trying to educate and put to rest worried minds. A wise man told me who not to argue with
