Industrial Injection Phat Shaft 66 Turbo

[BradyWilliams]

RE: Dyno runs

Just wanted to say that I talked to the technical people at Dyno Jet and they assured me that the comp. factor is what made the dyno accurate at elevation. That comp. factor was consistent with elevation at every dyno room that we have ran at. (Las Vegas, Salt Lake City, Aberdene, Idaho) 2,000ft-5,000ft. If someone at sea level uses a 1. 2 comp. factor then the numbers would be wrong. At Bullydog every one that I talked to said that the dyno was reading low 50hp. I believe most of those guys were from lower altitudes. I do know this, Scott bought a Phat Shaft super 66 and truck pulled at the Bullydog event. Please go to www.industrialinjection.com to see what he thinks. There were Sled Puller 66's there, Pro 52's and compound twins. Guess which turbo put up the biggest horse power for a single turbo. Answer Phat Shaft Super 66. And when you put the twins in the mix the phat shaft turbo still beat most of them. And we left the bigger horse power truck home. 688hp. We would have been the 3rd highest horse power at that event with that horse power. I'm not saying that this turbo replaces twins. Twins can and will always be the choice for the ultimate in horse power. But the Phat Shaft Super 66 does raise the bar.

I'll start by saying I am certainly glad we have more high-hp turbos coming onto the scene for the 3rd gens that will allow for more choices,etc



Do you happent to know the CF was on the 688 pull, I did not see it on the dyno sheet



Also what did you do to it to get it from 582 (5/7/05) to 688 (6/27/05)



Thats a pretty awesome jump in power especially at that level!!

But the Phat Shaft Super 66 does raise the bar.

That is may be but how much does it raise drive pressure at 45psi? How many times do I have to ask that question before you say I don't know, we've never measured lol? Who cares what HP you made on a 5 second dyno run if it's a tight turbo that chokes on 500hp+ fueling?

RE: Dyno runs

We installed a Snow water/meth injection system and a Fass fuel system. We were able to run the TST Power Max 2 levels higher and the water meth added a little. We have listed every mod. that has been accociated with that truck. We are going higher. Thanks www.industrialinjection.com

 

[Luke Warmwater]

I don't care about mods I care about turbo maps lol. Drive pressure... what does it mean to you?

 

[BradyWilliams]

RE: Drive Pressure

Luke on post 158, I listed the Exhaust back pressure or drive pressure as measured in the exhaust manifold. We have not measured that pressure since. But TST is doing there own testing and he is very intrigude with the low back pressure. Any one that knows turbos at all would take one look at this turbo and would know that the drive pressure is rock bottom. If you want to call me direct I would like to explain how we have accoplished this in detail. Thanks

 

[Luke Warmwater]

I will call you Brett. I did call once already and the guy kept telling me how great it bolted right up on his 3rd gen after I told him I had a 2nd gen three times lol. Sigh...



I'm curious as to how I would know by looking at a turbo that the drive pressure at a specified boost would be rock bottom or low for that matter? I suppose looking at a turbo in a picture in a static state I could assume drive pressures of about 14. 7psi? I'm just a novice so bear with me...



PS

Brett today is going to be trying something new. He is building a turbo with a k31 wheel to see the performance level. We will let you know the result. PS It barely fits!

Are you talking about yourself in the 3rd person or do other people post using your ID?

 

[pwerwagn]

How many times do I have to ask that question before you say I don't know, we've never measured lol?

Luke, he already answered your question:

The back pressure or drive pressure that was asked for was tested on 3 different trucks back before we released the super 66 turbo. The results varied a small amount due to different amount of fueling. The results were 38-39 psi. I hope this helps.

Brett, I dont see a review from Scott on your site. Or is this what you are referring to?http://svcs.dexclicks.com/svcs/dcc.....industrialinjection.com/feedback.html&page=1

RE: Phat Shaft 66

Yes that is the feed back page where Scott left his comments about our turbo. He is a great guy and knows diesel trucks. Thanks

Register on NWBombers.com - it's free, then PM Camotanker (aka Scott) to get details.



He was a Bully Dog Dog Days last weekend and did a full pull seen here: www.bhaner.com

Try something different then the competition, as I'm sure you guys know that the boys from Denver use the K31.



I really don't understand the infactuation with larger compressor wheels, the 5. 9 is only going to flow so much air with a fixed amount of RPM. You really are going to need a higher and higher boost pressure to get more air into the engine. So now your trim size is crictical. Larger wheels typically have problems with higher RPM as well their surge line is very poor. Combine the two and you have longevity problems.



An example would be using a 80mm compressor wheel, wow your thinking that must flow some serious air, the OD of the wheel is only 100mm. Which sucks as the wheel would flow a ton but it wouldn't be able to support any pressure at all. At higher boost pressures the wheel would generate so much heat it would be pointless to use.



Just remember the inducer size is only 25% of the equation.

 

[Diesel Freak]

Yep, big wheel = surging when under heavy load, and limited rotor RPM.



A while ago when I wrote my english paper on Twin Turbos, I came up with a little equation to "check" airflow to see if the turbo is usefull. It is for an OEM ISB with stock cam and head. Makes it real easy to see if a turbo can surge easily, and/or support the fuel you are throwing at the engine. It gives a "decent" approximation.



The answer it gives is in LBM/Min.



All you need is aftercooled density ratio, and engine RPM.



I use 74% for intercooling efficiency.



Engine RPM x Density Ratio x . 007959 = Mass flow @ those conditions.







The . 007959 is just a conversion factor... . dont worry about the math that went into deriving it.

RE: Phat Shaft 66

Chris thanks again for your interest in our turbos. We didn't say that was a new product we were going to sell. We have been doing a few what if senarios to not only see if more hp. can be made, but also to make sure our customers are receiving there best value. As before mentioned Borg Warner Turbo Systems are very interested and excited about our Super Phat Shaft 66 turbo. They sent us a 64. 5mm wheel that has not been released to the aftermarket. We have tested this wheel which is a smaller wheel. Comp. map looked impressive and engineers at the factory were high with expectations. We found less hp. and surging in the 2500 rpm range. We then used a smaller exhaust housing the results were the same except more exhaust heat due to more drive pressure. Thats when we tried the 71mm wheel to measure for our own information, what would be the results. Our results have proven that the 66mm wheel is in the sweet spot. By the way we didn't as you say, just intsalled the biggest wheel we could find. We have also done a great job with the turbine sizing. Our drive pressure is very low and turbine speed is good. That is why this turbo out performs anything else. It all boils down to air changes. I may need to remind you that the Cummins 855 cid. engine started out as a 250hp engine. Through a lot of engine, fuel and turbo research that 855 cid. engine is now 600hp. The market needs a large single that actually works well. Some people don't like twins and don't need 800+ hp and 100 plus psi of boost pressure. Maybe you should drive my truck and notice the difference. It represents what most people are looking for in a larger turbo. PHAT SHAFT TURBOS, YOU SHOULD HAVE ONE!

 

[Diesel Freak]

Ok, enough with the hype, and sales pitch.

post the friggin map

You mean I am not the only one that has been waiting? :-laf



With all the data posted (spools fast, great turbo, no problems pulling trailer), I wouldn't think we really even need a map. Afetr all, this turbo does everything so well, a map might spoil our perceptions of this great unit!



I have been patiently waiting as well. But, I think there may not be enough real data on this thing other than a the guys that have tried it. Ultimately, that seems to be what it takes.



I would love to see the map and a complete breakdown of drive pressure vs boost. Also, elevation, temperature and humidity would be nice. And, with the drive pressure, the exact specs that the data came from. Not that would affect much, but would give us an idea of the conditions of the data.



I don't want to discredit anything. I just want to see on paper what we are being told to be true. I like the feedback so far, but it seems too good to be true?

This turbo sounds great - my only problem is the core charge - Compared to the sledpuller 66 - no core charge.

If this turbo can do what Brett claims - Ill have to suck it up and order.

And I agree with Bret no twins for me.

hmm, didn't see that on the site. . A core charge?



What in the world would I send back as a core?

 

[Diesel Freak]

I can say one thing. If you have an anto with a really tight convertor, or like shifting lock to lock under HEAVY load (no not racing)... . expect some barking and rowdy behavior from a turbo such as this

 

[Tomeygun]

I expect delivery of my new truck in about a month. I don't leave things stock, and I've been researching upgrades - including turbos.



Since too many vendors rely on voodoo physics and smoke and mirrors for promoting their product, it's very difficult to get a feel for what is real and what is... well... voodoo.



No doubt, many great products have been developed by luck, relying on no real real information to substantiate their claims. The PS66 may be one of these. I don't know. At this point, no one does.



Since it does come to gut feeling on my part, I tend to lean toward using vendors who can effectively communicate their points. Croth is an effective communicator, from what I can see in this thread. Thank you to Diesel Freak, Luke, and others who have been pressuring for real info. Granted, I don't yet know how to read the info yet, but there are many here who can and post their interpretations.



Brett, again, I don't doubt that you have a good product - or even a great product. After all, you must have done something right to achieve those measured numbers. However, after reviewing your web site, I find very little information that makes me feel comfortable forking over nearly $2k for a part number. When there are enough people running your turbos, you'll have plenty people to validate your claims.

I made my choice based upon customers reports, and seeing with my own eyes

FWIW

RE: Phat Shaft 66

Positively no core charge. Never has been, never will be. I don't know were that came from. Thanks
