Let's try to have a thread to talk about the success stories of engine builds. All too often you see the bad stories of blown motors. I know after talking to at least four different VQ builders that there are a ton of DEs out there and plenty of built HRs. Please share your experience. Maybe if this threads gets some legs, it can be sticky'd.

I have posted an example of the information. Should we have a minimum mileage like 5,000miles or something?

Thanks.

With a long enough time table we all fail.

Plus most think they drive their cars hard and they don't. This is worthless.

This a community where 15k miles on a $6000+ motor is "awesome" it's fawking sad. Talking about grandma owners doesn't erase every build/shop failure.

You have a stock motor? Why are you even posting in this?

 

I was just posting an example. I have seen people posting, even in my grenade thread of success stories...30,000 miles built. I just want to see what is out there. There are tons of situations that worked out better than yours. Lets hear about them. We always hear about the bombs so this isn't about erasing a shop failure.

 

In all my years of constant reading/learning I can count the real drivers who actually kept a motor together with one hand. Stating 5000 miles as a success in your original post is IMO stupid, not even two oil changes? Would you listen to advice from a 20yr old on life lessons?

Don't believe me? Go search the past 5-6yrs of 500+whp cars who have successful drag times or who road race for real.

 

pretty sure we could all find this answer on the first 2-3 pages of the F.I, forum. I dont think i have found any great success stories with Built F.I. yet

 

The list should also include other important variables such as

• EMS used
• Who tuned it
• Type(s) of fuel used

I agree with Alberto though that this thread will be worthless in gleaning much useful information or definitive answers. There are just too many variables and often owners don't truly know why their motor failed. For example, they know they spun a bearing but don't know why they spun a bearing. Plus the driver variable isn't always clear and can be questionable. "I drive it hard" is such a subjective and relative term for street driving without documented track use to back up such a statement.

 

ill agree 5000 miles is not near a "success" but at that point it should have had at least 4 oil changes first one at 20 miles being the most important to clear out most of the break in debris.

definitly absurd with the lack of successful engines on this platform though.

 

Bought motor with 9000 miles on it. Put 3000 on it since so 12000 miles so far. Drive it like a Lincoln on the street and give it hell at local drift events every month.

 

subd.. for sure.

 

This ought to be interesting...

 

Dynosty stage one block (when it was inject per)
Greddy 18gs
12pds
Haltech

10,000 miles so far

IMO important to get built, parts, and tune in one place

 

Anyone that abbreviates pounds with pds has no mother fawking merit in this forum. I wouldnt ask for your advice on how to best pick up dog $hit.

 

LOL

 

I was gonna say, wtf does pds mean LOL. I'm stock so I don't have anything to contribute.

 

Any built motor is going to let go eventually. idk what you're spiel is about alberto. Regardless of vq or not, that's what happens when you beat on an engine. You can't avoid it really. Push an engine to it's limits and beat on it=fail eventually.

But I do agree that this community is full of fluffy crap. Either under pushed setups for wayyy too much money, or poontang drivers who dyno their car for a number set it on low boost and act like they got something... or both really.

I'm surprised GTM still is in business, but they cover their online tracks really well.

 

I don't think built motors should fail at 10,000 miles or less. Some of us haven't even gotten off the dynos, what are your thoughts on that?

Let It be clear I dont expect anywhere new factory reliability, but I imagine 25-30k shouldn't be such a long shot.

 

I miss read your point. I get what you're saying now, and I do agree.

Honestly believe it's all in your builder/the details.

Dynosty's engines should last usually around 3-5 years with reasonable driving... Maintanance is a big part of that and how the car's setup.
I'm sure we'll see some input from someone from dynosty... but I believe hal's still running the same engine, and now has 800whp... Eagle rods to boot (YEA BUDDY).

Tune, builder, maintenance, and driving style decide engine life... I've slowly come to understand the differences in these... What does beating on a car actually mean, and conversely babying? Can be a wide range... I know how I plan on driving my car.

Although that being said, track car vs street car vs DD are huge differences in driving styles...

 

From a scientific point of view to further quantify things I think that this attribute should be added:

miles/years on built block that way we can see if it was driving a significant amount of time or spent time in the garage.

 

I know that at least one of my customers (Don) really beats on his Dynosty built engine. Autocross, top speed runs, drag...ect. His car has been holding up very well to my knowledge, but I am not sure how many miles are on the build. Whatever the miles, they really are HARD miles. Perhaps he can chime in on the details.

 

I think I'll add to my previous post and say, this thread is going to ultimately leave everyone un satisfied.
There's no concrete way to put data to blown engines. How they were built, driven, tuned, setup all have sooo many variables that it's pointless. Even with QC in the mix... it's just kind of pointless.

If you want to make your motor last, have it built by someone who knows what they are doing. Discuss your hp goals/torque goals, turbo system, your driving style and general purpose for the car with them. See what they have to say. Ask them how you should setup the car.
For example, 500whp from a vortech is way different from a jwt 500 kit. Simply in how they make power is way different. There are ways to setup cars to change how power comes in to make your internals have more longevity... Stuff like this has been discussed before, and I'm sure these guys have heard it.
IMO this thread is going to be another one of those "how long is a piece of string" ideas. In the end, race/high hp engines don't last. Do your research or have a good shop guide you through the entire build and it will last. /endthread
