how well does the super fat shaft 62 work

[BradHanson]

who has used the super fat shaft 62 and hw well does it work. How fast does it spool up, what boost are you getting with it. , and how well does it work for towing and keeping temps down. I am considering on getting a super fat shaft 62. I am running a 03 SO with a stage 2 afe, 4" proflow exhaust, edge hotjuice, bullydog tripple dog, and various transmission upgrades. any help would be appreciated

It"s awesome, It Keeps right up with My modified Rail and spools Nicely.

Alot of people here have downgraded from the SPS 66 to the SPS 62 for towing and they report its alot better for towing, from my experience the 66 has a bit to desire for towing. Its a great turbo dont get me wrong but it will surge under a hard load as where the 62 shouldnt. I can drive right around the surging with no problems because I really dont tow that much and when its lit up hang on!

 

[CATCRACKER]

we had this debate long ago about over sized turbos. my feeling are for what i do towing heavy and 55-85mph runs on the interstate a smaller turbo ie 62vs66 is best for me. i like quick spool and higher egts also thats what water/meth is for . i am not a sled puller but i do tow heavy and i dont like thick clouds of smoke when i hammer it on the interstate. I like quick spool, hard hitting, low rpm tq. All you need to do is look at T&C making 550 with a 62. There have been other people who have run 62,64,66 and are now back to 62 or twins. Oh yea I am not trying to win hp contests. I am going for 550hp and will be limited with my sbFE. Of course my races are on the interstate and a 62 with quicker spool 55mpg-85mph is hard to beat. I would trade short burst high egt's for lag anyday!!! Also if you go twins the 62 on top in a twins config would be hard to beat. If all you are worried is high dyno numbers silver bullet will take you as far as you wont to go to win local contests. ok enough of my blablabla



this questions is as almost as hard to answer as which transmission to buy

 

[HeberRam]

Industrial Injection SPS62 is the best on the market today... hands down Oo. Oo.

 

[JCleary]

Yeah, I don't even tow and I'm thinking about "upgrading" from my SPS66 to a SPS62.



I want quicker spooling, but no egt troubles either. I guess the switch will be to a 62 and water/meth.

 

[CRiggan]

The SPS-62 is a great turbo for overall performance . . Spools just as fast as stock and will hit 60 psi quick with my set up. I really like the turbo because its kinda right there in the middle between big and small. It will give you tons of pulling power and cool egts, yet when you want to play around, you have massive power on tap.

 

[BradHanson]

thanks guys , it is sounding like the turbo I was looking for.

 

[JasonCzerak]

So where does the Silver Bullet fit in here in regards to the SPS62's drive ability and max power?



60PSI of usable boost, usable = cool boost? this with a good innercooler as well?

 

[CATCRACKER]

i am no expert but 60psi out of the II62 vs silver bullet is like night and day as far a air density due to air temps etc. the silver bullet is a huge single that is for making big hp number. I have run big, small, and medium turbos the II62 from what i read is the real deal. That is the one (II62) i am going to run and eventually plumb it into twins. Heck if the stocker was a little larger say like the hx35 or 40 and i knew it would hold togther i would leave it on there

 

[WUnderwood]

I think the phat shaft 62 would do great if your towing heavy, and dont want surge or stall. I have a II Silver Bullet, and am very happy with it, although it is a little loud

 

[CHolman]

Man let me tell you I couldn't be happier with my SPS 62. I towed my wifes car the other day on a flat bed to the shop and the out side air temp was 101 on the over head. I barely touched 1000 degree's hammering it just to see what kind of temps I could get. Ususally WOT I'm around 900 empty, but cruising around I'm around 580 to 600. This thing lites pretty darn fast. Like CATCRACKER said it will support 550 RWH and I'll never go over that. I hit 49 to 50 PSI MAX with my set up. I love the whole set up.

I wonder if mine's messed up then. I got it on last Saturday. It makes a lot more power but it's hotter at cruising temps, which I'm told is normal due to lower boost in the same conditions. But if I'm just playing around with the TST up I can hit 1350 at full throttle empty. I'm wanting to hook up to heavy trailer to see what difference it makes. It is set to 40 lbs. though. Could that be a problem?

 

[CHolman]

Well you have a 04. 5 mines a 04 HO (305), so that might make a little differance. I have 5" turbo back, another factor is the ATS exhaust manifold & ARCH Flow manifold. I'm sure they don't help a bunch, but anything to make your truck breath easier and not make it work as hard as a little factor. I'm at sea level, there's a bunch of factor's in how hot your truck runs. What does yours run empty cruising? I have the BDPP set on Performance (90 HP) I don't know if you have a 6 speed, but there's another thing to look at. I have 373 gears, so my RPM's at 60 are around 1800 RPM. Your also stacked with the TST and edge, I could go on and on, but I'm sure yours is fine. :-laf

 

[Latenight6]

i loved mine since day one quick spools even when towing. egts around 1100 when on 20% hill great puller Oo. Oo. Oo.

 

[CATCRACKER]

it is my understanding that like mentioned before the 3rd gens spool turbos better but let me wet the record straight the II62 is a hoss that flows lot off air and it is a big turbo but the II66 is just bigger. i remember when i first started in this diesel thang in 1999 thing people where using hx40's to sledpull with . . hx40 are garbadge compared to these new line of turbos. i also knew a guy when the hx55 started coming out and some custom singles where out there and they cost $2800 and they sucked compared to these new turbos. keep in mind 550hp is no small amount of hp and will make most people happy. the trade of for little too much lag(IMHO)for another 30hp in my book is not what i am looking for.

 

[JasonCzerak]

I been learning alot bout these trucks. So far I'm just laggin on the knowledge of the injectors and turbos' and the dynamics to make things go fast in regards to upgradding the turbo and injectors.



I thought the silver bullet was to compeate with the SPS62/4/6 class of turbo?



And my turboupgrade is looking alot like the sps62. But I'll get only about 100HP from it? I'm at about 450 (for sure once I get my fass in).



Would that 550rwph be at rather lower PSI and EGT numbers? Could it make 600 - 650 if you push things a bit like I'm pushing my stocker (40+ PSI)?

 

[Jim Fulmer]

Jason I wish I could give you more info on the SPS 62 but the timing is just not right. I have a local 12V that is at 440 on fuel and 490 on water with a stock turbo and he too want to jump to this turbo for towing purposes... ... perfect candidate for R&D as he has a dyno too.



I have a HX-40 also and it does not compare to this turbo or my SPS 66. I'm running the 66 as a single now and the power is good to me, better with water..... most people would freak as it's a little spooky at WOT..... nothing new for me.



I don't see how you can go wrong here but it's your $ not ours. If I didn't go to this turbo I would stay with an HX-35.



Jim

 

[CHolman]

IMO, I would say 600 to 650 RWH would be pushing the SPS 62... I know that for like $400. 00 you can up grade to the SPS 66. As long as you have a Super Series turbo you can upgrade or degrade. I started with a SPS62, but unless I win the lotto will never reach over 550 RWH... If I where to win the lotto I'd leave this trick alone and build me on hell of a truck, kind of like BBD, but with a thrid Gen...

 

[CATCRACKER]

for my needs and what i do the 62 is porobably as big a single as i would go with. so for my needs if i wanted to use my truck like i do and wanted to go bigger than the 62 for more hp than 550 i would have to go twins and get a dual disk clutch. this is in another league as far a $ is concerned. i had a 460hp 12v with a stock hx35 and that is partly what i am basing my opinion on. My buddy has the sp66 on an 06 3rdgen tst twins crazy larry fass etc he made 500hp I think his truck is a little to laggy for me if his plan was to stay a 500. He plans on injectors which even with injectors he could would have been better off with the 62 but when he does the pump the 66 is the right move... know (realistically) where you want and how much you will have to spend before you start building your truck this will help the proffesionals and the people on this board tell you how to achieve the best results with the cheapest route.
