Precision Turbo Billet Wheel Information

Billet Buick options

Regarding your first post John, if the 72 and 74 are designed specifically for the imports, are the 71 and 76 the only choice for the TR crowd in this range?

I haven't been able to find the 09 rule changes for TSM. To keep the class up to date could the billet 71 become legal since there isn't a billet 70 available yet?? Just wondering!

I am currently in the market for a 70-76 and a converter, great info. I think billet may be the way to go. Thanks!:biggrin:

how are the 72 and 74 being designed for imports? Are they suppose to work in the higher rpm's? I am under the assumption the exhaust gas is exhaust gas?

71 is legal. I doubt these turbos were engineered solely for Buick TSM cars since the cost of development would net almost zero return. If your not running a heads up class buy a turbo that will hit the target hp without being the limiting part in the combo. The turbo will still be a limitation in TSM billet wheel or not. NO gain on the hot side:tongue:

The compressor map will tell where hte turbo is in its most efficient range. A 72 and 74 would most likely need to be pushed to 6500 rpm and 30-35 psi to be in the area where its designed to work. Thats with the tangential ex housing too. Never happen with a 3 bolt. How many guys on here have 3.8's capable of running like that? Not too many and definitely not many of the stock blocks. Keep in mind the later imports have much better basis for making huge power with way less chance of block failure. There engines can often be run many passes at over 1000hp without ever worrying about the block failing. The hard running TSM engines may get a few passes in that hp range and block failure is still going to happen.

Full Throttle offers the billet wheel 70. I have one!!! Dave

 

[Bent6]

Sorry but I think you may be confused with the ball-bearing and/or "boosted" version as there currently is no BILLET 70mm wheel. There are a lot of people waiting on that one...........

As John stated above:

These are the wheels currently offered:
60, 62, 71, 76, 88, 90, 94, 106 and 114

These are the wheels in development or pre production:
55, 58, 67, 72, 74 and 98

Thanks Will, you can't trust that John guy!

How long has the billet 71 been out? Will this then make way more power than the 70hpq? Seems as it should since the billet 62 makes more power than the standard 67.

You are somewhat suspect at times - what are you, some kind of newbie:biggrin:

John

I read that quote earlier about the billet 62 making more power than a cast 67 - I would like to see that graph - what engine, exhaust wheel, housings etc is this graph based on? If the exhaust wheels/housings were equal, I don't see a billet 62 making more POWER than a 67 even if it is a cast wheel - it should have better spooling characteristics but not necessarily any more peak power. 67 turbos have run in the 9s - as good as it may be, you would have to whip even a billet 62 to get bottom 10s. This is why I have waited on the billet 67 for my latest street creation.

smaller billet wheel making equal power

I was looking into upgrading and i visisted a shop in miami that is very well vered in turbo stuff. I was inquiring on the 67 normal precision turbo. I was told that they used a smaller billet 63 (?) wheel and that it is making the same power as a 67 that they have used before on Evo's. I looked at the wheels side by side, the length of whichthe wheelactually passes air though it or compresses air, is jusst as long in the smaller billet and the larger 67. the center part of the wheel which is machine in the center is thicker on the cast. im not sure if thats very scientific, but it made some sense when i looked at it. the guys basically told me that instead of the 67 to go with the smaller billet that would give equal power/flow with less lag.

Bent6,

So what stage are the 70mm billet wheels in? Since they are not in pre-production and development, are they still just a thought or wet dream?

I am eagerly anticipating this turbo as well, but have no idea when it wil be released. One source told me a months time, but i just do not know.

I wouldn't hold my breath on that one - it's been "in the works" for well over a year now. All I know is that there have been some billet 70s tested but that's still where they are at this point. I was told a few months back by someone in the loop that the testing on the billet 70 wasn't really that impressive over what's available right now. I don't know why they are making and have plans to make about every size other that the 70mm at this point. Someone like Cal or John Wilde probably has more specific info.

I was told this is a billet 70 wheel by Rick Head of Exile turbo when I had this rebuilt for the 3rd time. It was the Innovative 70/71 X-trim of a couple years back......

 

[Bent6]

I've never really kept up with Innovative stuff or even Turbonetics for that matter. Rick Head knows his stuff for sure - that definitely looks like a billet wheel. I've heard of some people taking larger billet wheels and "cutting them down" to custom sizes.

Will it is my understanding the Innovative used billet Borg Warner wheels.
The new Precision stuff is different, Harry is excited about it.
He told me the 67 is about a week from being released and will be a 800HP
quick spooling turbo. The 67 billet wheel has already made 830 to the wheels on an awd evo. The new 71 should make some big power, I am not sure if there is any public information on these yet.

Keep in mind John Gallina went 203MPH on his second or third hit with the new billet 76s. They also spool faster than his old units.

These new wheels are not a joke...

No doubt they aren't a joke. As you already know, I'm on the list for one of those billet 67s for my street car - it will be configured with H-cover and .63 exhaust housing so it should spool like a stocker - should be an absolute animal on the street. And don't worry John - I will give you a "FULL REPORT" as soon as I get it!

I contemplated upgrading to a billet wheel on the race car when I toasted my 91.5 @ BG last year but decided the performance gain wasn't worth the expense since we already use NOS for spool up. As the billet wheel technology proliferates the racing scene, I may change my mind. This is some kool stuff!

 

[stk6bngr]

so with the billet wheels being able to spool faster does that mean alot lower stall speed say like on the 6776 ive been reading that 3200 is a good stall for that turbo. with the 6765 billet wheel does that mean u can spool the turbo fast with a lower stall??

The word I would use here, would be easier!
The Billet Wheels are lighter weight and stronger, therefore it is easier to spool up. Plus with it being stronger, they are getting more horsepower from these smaller turbos! So Yes, you do NOT need much stall!
The New 6765 billet Wheel turbo, should out perform a 6776 turbo. These New Billet Wheel turbos are rated 850+ horsepower and that is a conservative rating!!
I have several of these turbos shipping out and can't wait to get some results from my customers.
Now is the time to order one!!!

So what you're say'n Holly... Is that the billet 6768 I have coming is gonna make one sick street car... :biggrin:
