How many thousand km can u get outa astroker engine ?

[Poraga]

What the title says ans i mean 2000cc up

[FreeBug]

Easy, take the number of miles a stroker can get and multiply by 1.6 for a rough answer.

In a buggy? In a bus? Lovingly driven or overheated, overspun, and no maintenance?

Sith good oiling and assembly, the limiting factor will probably be the heads, needing a refresh around 80-100'000 km or so, again depending on parts and use.

[modok]

nearing 100k of those kilo-maters on my 2007cc lifters excluded.

High revving mini-strokers, and low revving BIG CC engines often do last a LONG TIME.

But I take it the crux of the question is what combo of RPM and stroke starts to become a problem and the answer is..........well, ummm.. good question.

[Poraga]

So after about 100k freashin it up? New seals,replace anything that needed replacing etc?

[Poraga]

Mine is a 2276cc wedgemated crank making about 180 hp at the fly aluminum block so on ran on the best oil etc exteral oil cooler etc and revs to 8000rpm

[modok]

I think the rings will go first.

Each is different, it's hard to say what would wear out if it was perfect to start with, because nothing ever is.

I like the Berg idea of using a pliers on the valve spring to gauge guide wear. That's a cool idea. usually guides go first but I guess since I have really good guides and conical springs maybe not.

I know I am more skilled now than 5 or 8 years ago.....so how long will the engine I am building now last???? I hope I live long enough to find out. I think I will. Fingers crossed.

How many miles can you stand to drive in a souped up VW???

8k rpm on a 82 stroke is going to have a short life. But with an aluminum case.....might be longer than I think. The valve train isn't going to live long either ya know. Unless ithas the worlds best cam and lifters I'll predict 10k km.

[Poraga]

The answer to the soup up part as long as i can drive

[Poraga]

O about 10k with that build just cost me 7k

[modok]

Naw, It'll just cost ya whatever broke. It is possible to destroy an entire engine in one kaboom but I've never done it myself. You just have to shut er down before the smoke starts coming out and/or clanking gets too loud.

[VWCOOL]

Unfortunately, I have seen several present-gen 'big name' stroker cranks crack/break inside 30,000km

It's not the 'stroke' that does the damage... it's the poor quality of the crank itself.

That's a real painful lesson for someone who has been led to believe that a 'new' crank will outlast a forged VW crank that is good for 200,000+km , even when used in high-performance applications.

You don't always get what you pay for...but you pay for what you get

Maybe something to keep in mind

[Poraga]

Thanks guys for the feed back lol i guess ill enjoy it while i can

[VWCOOL]

hell yeah...!

[Poraga]

So i just keep tearing it down when stuff goes wrong etc thats the aim of the game? All so this is street drives 2,3 times aweek maybe 200km per time but not all ways trashed though but i have a heavy foot n am a hoon !

[mark tucker]

there are many factors.including the machinest,builder,owner,machanic,driver,location,prep,parts,cr,fuel oil, loose nut,tight nut,cooling system,maintnance and so on.Im sure you could get atleast 800 miles or so....but Ive seen less.100000 should be no problem.....for some.

[Poraga]

Ok ill just drive tiill something happins i guess lol?

[Poraga]

Lasr post was retrard no offence but yea it was i mean wtf 800miles or 1000000miles theres nothing to add why even reply >_>

[57 Rag]

Wellllllll I was told by my engine builder not to expect 50k miles outta my engine. I told them wow that's more than I expect!!! I look at it the other way. If I'm getting high miles outta my motor, either I'm driving it like an ol lady or it's not rowdy enough. Lol

It just depends on how well it was built, the quality of the parts that were used, how well and efficiently it 's burning fuel, the rocker geometry, maintenance, and sometimes, just luck.

I believe for stroker 2.0+liters, a 78mm crank with 5.5 rods, a cam with gentle ramps, thick cylinders, and heads with single springs has one of the best chances to make over 100,000 miles.

[Quokka42]

We usually use better than stock components, so much so that there is no reason a stroker can't live as long as a stock engine - if it is driven like one!

A mature driver using the engine but not constantly thrashing it can easily expect over 100,000k, but boy racers often break their engines in a few thousand k. Being young and inexperienced they also tend not to recognise the signs of failure and keep going until it fails completely.

I remember when I was young someone killed a hemi after about 500km...

Well the OP says he has a 2276 throwing out 180 hp. Not much people build an engine like that and gonna drive it like an old man. If you get 100k outta of it your definitely not driving it like it was meant to. you can always sell it if you want 100k and build a nice 2007.
