Silver Bullet turbos

[lmills]

You know I have this SB on my second gen and have NO surging issues. I have yet to see somewhere Brady posted about surge, other than him posting about the SPS66 on a second gen... ... ... he has posted that. I said it before and Brady keeps asking me how the turbo is doing on my truck, working like a dream I tell him everytime, later Jim

Oh really SpicyJam? This came right from your own post on the cummins forum.



"You know we are always trying to improve our turbos. We still show that a SPS66/80 is doing a great job for people. We have made a nice increase with our Silver Bullet and it looks to be able to make the 800hp range. It is very driveable and the comp. surging shows to be very minimal. There have been many that say they would like a 71mm comp wheel. We can do this change but I will say this, you may see a little more surging with the bigger wheel. This is why we don't put that comb. in our product line. Silver Bullets make a VERY impressive amount of air. It's all about turbine speed. If you are interested give us a call. Thanks"

I wanted to get a few runs on the turbo before I posted anything , but I have had mine for about a month now, I am very impressed with it, this thing pushes gobs of air and I haven't noticed any surging problems with mine. I raced Saturday and ran a 12. 337 @109. 5 pretty much up against my speed limiter. Yes I am happy with my Silver Bullet!!

What injectors are you running?

I guess I am not sure what you are saying, he has still never spoke of surging issues with the SB, I said he has with the SPS66 and I knew it surged. I will stand by the fact that I have no surge issues with my SB... ... ..... what he does say posted above is that is you want the bigger 71mm wheel you will have as he puts "it more surging"... ... ... ... ... ..... and since I talk to Brady almost every other day he has yet to inform that there is any surging with the SB on a 3rd gen, and with me owning a VP44 truck you would think I would surge bad, like some of the 64s and 66s I have put on other 2nd gens... ..... so I would like to know what your point is?

When you go back to the dates of the post on Cummins Forum the Bullet was very new... ... I was number 4 to get one outside of his 2 shop trucks. I know he had some issues with one of the trucks before May Madness and had not really had the chance to do some real world testing... ... ..... I have, and have 0 surge... ... ... ... . later Jim.

Imills, these other forums are always off on there own agenda's, and for the record I have never said that the Silver Bullet has a compressor surge issue. The Silver Bullet is as clean as you could ever hope for with a VERY large single. I should spend time policing the other forums, but I don't have enough time to do that. What single will give you over 30psi to launch and run 75+ psi to make big hp? After seeing what this turbo will do I am impressed! We are having larger comp. housings made and should be in very soon. This new comp. housing will be for a 71mm comp. wheel. This configuration with the larger wheel will be for those that just has to have the maximum sized wheel for their sled pulling class. The name for this new turbo will be the Silver 71 and we will launch it through our dealers/distributors at that time. The turbo does work very well, but to say it's better than a Silver Bullet it is not true. A 71mm wheel just wants to surge on a 5. 9L engine, but on our new Silver 71 it's very minimal. Thanks, Brady

[lmills]

you guys crack me up, really! Don't shoot the messenger. I never said it. I just quoted what was previously typed by you, Brady. This was a quote that was taken from something you wrote about the turbo.



If you all had taken note of what else I put, which you obviously didn't. You would have seen that I wrote that surge issues can plague any turbo. Not just your phat shaft ot the silver bullet. It is a combination of a lot of things. Just like the 12v trucks will sometimes surge with phat shafts faster than the electronic trucks.

 

[BradyWilliams]

Yes I read what I wrote and the meaning may be different than the way you read it. But yes I crack my self up all the time too. The Silver Bullet is a large single like I said and yes some where is this world there may be a surging Silver Bullet at some point, but you know it has been a very impressive turbo todate. So if there is anything I can do for you we would love to. Thanks, Brady

I have a few II turbos. . My question is for my 05. . Would an SB72 be able to tow? I have your PS62 on it currently. My 62 is a little odd. It barks between shifts, though it doesn't surge. If the 72 can tow, is my 62 upgradable to a 72? Thanks. .

I can make my 66 surge with about 7-8k behind it in the hills of the Sierras fairly easy. I cant make it surge empty though. The bark between shifts is just huffing, a sudden loss of drive pressure/rpm's while still trying to force air into a motor that cant swallow it all, most high boost applications will do this if the conditions are right, its really nothing out of the ordinary. A BOV will help with this but they can overspeed the turbo and you will have a harder time recovering boost while towing.

 

[BradyWilliams]

Morse, The Silver 71 isn't going to be advertised as a towing turbo. Our Super Phat Shaft 62/80 is a very good turbo you can tow with and would be a nice upgrade. We have been towing with our Silver Bullets and they are a good tow turbo. But the Super 62 is our turbo of choice for towing. Thanks

Bret, I have your PS62/12 from Floor-it, would it be any advantage to me to have it changed to the Super? Thanks,



Larry

oh there's no doubt it has been impressive.

 

[BradyWilliams]

Yogibear, You would drop more EGT's and the performance would be much better. You would see a VERY big advantage in doing the upgrade. Let us know if we can help you. Thanks, Brady

What is suggested to run along with the Silver Bullet? ATS Manifold? Blow-Off Valve? Boost Fooler?



I have all of these items: Head Studs, Banks Techni-cooler, SBC DD, Hot Juice, aFe stage 2, FASS 150 modified, any other suggestion to run Silver Bullet.



I have heard a single that can blow away twins.

Is this true, how about spool up compared to stock, other brands? ]

Thanks for all help and info, getting ready to buy turbo or turbos soon, want to soon make a decision.

 

[mattymac]

I think if you tow with 450 HP and up twins are the only way to go. I love my 66 for driving around town hot rodding but when I hook up to a trailer its a diffrent story. I need a 62 for towing (so it doesnt surge) and a 66 for empty fun. A moderatly sized set of twins I think would be your best bet.

 

[AMink]

I've looked some for this, but haven't found an answer that I can wrap my brain around. What is surging? Is it when a turbo runs the boost up in "steps" instead of smoothly? Why is it more prevalent in a larger single?

 

[SpicyJam]

Suring is when the turbo actually stalls out, almost sounds like barking. So far I will stand behind what I say about the SB, although I have not towed heavy nor will I with the injectors I run. I know Brady towed his truck down to May Madness and the truck he towed with had no issues with surge either. Hope that helps at least answer what a surge is.

 

[yogibear]

Thanks Brett, I'll be talking to John.
