highest hp with silver bullet single

[HT3500]

Ok my question is whats the highest hp anyone has done with a II bullet? What kind of life is everyone gettin out of these turbos? I blew mine today and it only had about 2k miles on it...

[triton]

I'd be interested in what caused it to blow ? I did 700 with one but, I know there higher.

[CREED1]

Kevin did 1013/1587 in his 03 with an off the shelf II silver bullet 66 he has a modified sb 66 on the way. This was with a small shot of juice also. He is the highest I know of on that turbo alone.

PM Will Underwood about his silver bullet experience!

[Camotanker]

wheres the pix????

[Jim Fulmer]

Buck, sorry to hear about your troubles, I'll be thinking of you when I pull my motor out after the holidays.

What boost were you running?

The last time I was down mine ran at 70 psi on the bottle, way to much for me. I have/had it set now were the max is 55 on the street(bottle) but it takes away from the #2 and makes it hotter when your on it.

[HT3500]

Jim didn't know the boost cause no guages.....ya I know, no time, but if I had to guess some where around 80 or so...look at my avitar. their is also a link to a vid in comp section on dtr..

[973604x4]

well done Buck. I have a SilverBullet and ATS manifold for sale if you are interested LOL

I'll even deliver

Yep, Kevin did 786 on #2, and 1013 on the juice.

[edgerat]

Garmon did over 1000hp with a shot of NOS but I think his was gated down in the low 70's like Fulmer mentioned. FWIW when I talked to the guys at HTT a while back they said that these turbos can handle that but not a bunch of times. And yes I know I am referring to HTT turbos and not II but the same basic turbo.

[Jim Fulmer]

After 65 psi you start beating on the thrust bearing too much, plus the drive pressure is way up there, probably 90 or so.

I.I. pushed it to 90 before to find the limits, they did.

[B.A.Ram]

Is there a difference between how much fuel only hp it can handle and how much NOS it can handle???

Yes, the wastegate needs to be setupfor different opening points depending on doing fuel only or nitrous.

To use it effectively with nitrous then the gate needs to be opened sooner to keep the turbine speed from getting nutty.

Like the way mine is setup, everything is give and take.

Exactly *nx*

[RowJ]

HT3500 was at 935 hp when she blew! And that's on a notoriously stingy, older Dynojet (with heavier drum, I believe) that reads 10-15% lower than 248c Dynojets around Dallas.

Do the numbers count if you don't finish in one piece? ;)

[smokinrod]

Red stroke did 1111hp on the dyno and then went to the track and on the first pass it went BOOM and it was NEW. three runs on the dyno and it was leaking oil allready. yes I know after that we shouldn't have went to the track LOL

[Robertp]

not sure what exact HP was made, but we went 10.90@125 in a 7200lbs CR truck. single silver bullet from industrial injection.

[Hammer]

We had a club member do 742/1200+ on fuel alone with a 04.5 CR,dual CP3's and other fuel related goodies with a Silver Bullet.

We also had a member break one on a 12v with less than 5k on it on the street.He came out to start his truck to go to work and POP went the charger,no rhyme or reason why it happened........Andy

[HT3500]

well guys got the truck running again, nothing got hurt motor wise. On the turbo issue I'v tried a couple different singles and nothing comes close to the silver bullet as far as street manners. So I will go back with another just cause it was such a blast to drive. Industrial did tell me there comin out with a new K31 that is very streetable, we'll see...

What is the modified SB? What do they mod?

[WUnderwood]

bigger wheel--71 mm compressor vs a 66(stock) I believe

not 100% sure

[zstroken]

In the s300 frame?

[WUnderwood]

I think so, they just put bigger wheels on a stock Silver Bullet

[triton]

The SB has a 74mm wheel. It's the super Phatshaft that has a 66.

I'd be interested in knowing what a modded SB has done myself.

[zstroken]

The turbine section of the SB has a 74mm wheel, the SPS has a 71mm turbine wheel. The ps has a 65mm turbine wheel. I think he was referring to the compressor wheel. SB has a 66 mm compressor.

[kxhonda]

Very streetable k31 huh? Better than a Aurora 5k? Sounds interesting

Well this is one of those real fast quick spool wheels thats the extra top secret Silver Bullet Upgrade!

[WUnderwood]

^^^ was that before or after the 1111 dyno run?

Silver Bullet--the ultimate single? I think not:bang

[Bosshawg600]

I personally like my HTT Pro Street 71. Made 856 fuel only and spools great on the street!

[Red Stroke]

It made it through the Dyno, but the first pass down the strip wasn't so special.

[Sliqwille]

I just murdered my SB this weekend with 716hp on the dyno. Anyone know of a "bullet proof" single with nitrous, 'cause ths is getting expensive.:doh:

[Mike D]

Anyone think that the ever increasing wheel sizes in a S300 frame is the problem?

wow you must have been running lots of boost, I did 5 runs back to back at 730ish with juice. And I know Jim Fulmer is at 800+hp with his bullet, and we all know how much he has dynoed...

[Red Stroke]

Uh yeah a 50mm JGS Gate will save any turbo on the juice!

[Sliqwille]

I could only spool 26psi on the dynojet. Spools, well, spooled 55 on the street.:hehe:

[Muddin_dude06]

I think those S465's Smokem has would be a pretty bullet proof turbo. Plumb an external gate around it for nitrous and I think it would live through anything.

[Jim Fulmer]

I actually have the SB in the mid 50's on boost using the bottle. The down side is it's not enough on #2, WOT is fine but 35 psi at 1200 degrees is not!

What it needs is bigger holes in the gates so you don't have to loosen the gate up so much. The way I.I. sets the gates is perfect for #2 only but not with the bottle, too much boost! I typically ran 65-70 psi on the dyno using N2O.....too much and 40-43 on #2......just right. Big, really big boost will beat the thrust brearing out.

Everybody remember when you could only run an HX-40 at 40 psi and N2O would send the wheel to the moon.

Jim

[Kman9090]

I run my SPS66 to 55 daily. I've only had it on for about 5,000 miles though with no problems.

[Jim Fulmer]

Don't know about everyone elses but mine runs at 47 psi on the road, that is the 1 to 1 crossover point. I've run it to 50+ before and I can't tell that it runs any better but the drive pressure is past 60 there........FYI!

Jim

[COMP461]

Project X typically runs 45 psi boost on fuel only 837 hp and on a .125 NX it made 947 hp.

The silver bullet is one of the most versatile big singles available. Project X has run traction limited low 11 seconds passes, at 129 mph. This turbo has 250 ¼ mile passes on it, with over 50 Land Speed racing passes on it also. The LSR passes are 35+ seconds of full power, full nitrous, netting 165 mph and several ECTA records.

[Red Stroke]

OK I figured out how to post pics!

So is that the end result of a 400 shot? LOL

[Red Stroke]

No more like 500 hp shot!

Turbo go boom LMFAO

[COMP461]

It’s critical that when you run a lot of NX you loosen up your wastegate. I like to use an external wastegate with race engines, this way you can regulate the drive pressure. You can open a waste gate up and reduce drive pressure and compressor out temp and in some cases not loose any boost


What were the drive pressures on this before it let go, I like the ability when you reaching this level to go ahead and buy a good quality data logger, Brady at II and Randy at RPMPERF.com have a great turbo speed sensor , and this can let you tune to wheel speed .

We have a saying in the fire service; there is always a method to destroying anvils with rubber mallets

[Red Stroke]

The boost elbow screw was fully backed out for all of these vids. I couldn't tell you where any of my gauges were, at the strip? On the dyno I was seeing about 62 lbs of boost. I agree a data logger would be nice, kind of overkill on a street truck dont you think? How much does a turbo speed sensor run these days?
