OK, but that's not a 6766.

But, the larger question is have you made 700wtq @ 44psi on a properly calibrated Mustang dyno with that turbo?

 

Thanks for the convo :-)

 

PTE compressor is 67mm Inducer , 87mm Exducer - Turbine Inducer 74mm, Exducer 66mm

I enjoy the convo too.

How long have the t4 housings been available for the 6766?

 

They have offered the T4 housings for a while now but I'm not sure how long the T4 divided has been on the market though. We were recommended to try it last summer by our PTE rep for our build so its been out at LEAST 6+ months now.

Exactly. A big T4 turbine on a 6766 on a Big motor will easily have the flow to make1000 tq. It isn't what a v8 guy might want but it is very easy to do. A smaller housing would choke total power but at 500HP worth of airflow there would be zero backpressure on a 66 turbine wheel housing so the low pressure needed is very easily achieve. I would even think on a Big t3 it wouldn't be too hard.

Jamie just because the Dynojet guys couldn't figure out the math in theory doesn't mean they couldn't scale it correctly. People have been able to measure things for a long time and not understand why it worked. A Dynojet is way more repeatable and in line with most engine Dyno results. Mustang Dyno numbers cart way too much and can be manipulated. I could show you a thermometer in the middle of August in Florida that says it is freezing out and just because it is lower it is not more accurate. Just because people get off on saying they went 9's on 400whp full weight doesn't mean they really did. Their low reading Dyno and tub can cars are the way they attempt to make themselves look superior. Anyone with a brain should are right through that. Just like anyone should are through artificiality inflated numbers. HP is a known quantity and the math is easy to figure out.

 

And the 65/66 series turbos have had T4 options available for a long time. I have been a PTE distributor for years since PTE sold Garrett parts so I would say I am familiar with their products as well.

 

You do realize I hit you with 100% facts from the INVENTOR of dynojets actual admission that the actual math didnt give him a number they "liked" so they just made up whatever formula they wanted, right? I'm not saying any dyno is more accurate than another, I just was pointing out your misinformation as fact was just your opinion.

Nice result just got to see this. PTE looks like a winner but how long will it last is the question.

 

You missed the point. I could take a thermometer with zero marks on it. I could not know any of the physics behind why it works and sit it in ice and Mark it then sit it in boiling water then Mark it and divide it up in even marks in between and I would have an accurate thermometer. Start with a few known quantities and measure. Dynojet knew the power of a motorcycle and couldn't get the math right so they used a scalar. It worked. Had they been smarter maybe they could figure out the scaling the "right" way. You aren't teaching me anything.

 

You do realize that HP is a constant and there is no variable or debate as to what one HP is? So if have two different measurements one or both are wrong. There is only one correct answer.

 

I already taught you this statement about DJ's was wrong. So I did teach you something you were unaware of and were boasting as gospel.

I agree. At least I have proven to you that dynojets results are NOT correct. I can't say any other dyno's are correct, just that theirs are factually incorrect.

You still haven't answered my question - Have you ever owned a turbocharged v8 vehicle?

 

I haven't owned a Turbo V8 although I have worked on a couple. Believe it or not you can know about something with owning it. Buying something doesn't make you an expert.

 

If you read both articles you will are that the Dynojet guys adjusted their formula by a scalar to make it match the load cell Dyno numbers which is considered the standard for measuring horsepower. The admit they weren't mathematicians. If the Dynojet agrees with the load cell Dyno and is repeeatable and works with all accepted math formulas I would say it is the most applicable measure and while not accurate to the smallest margin it is the best there is at this time.
