I've decided to drop some coin into some air for my way over fueled truck. A compound set up is not out of the question, but I would like to stay as a single. The 63/71 has kinda tickled my pickle as a single. Also some of the ball bearing Garrett's.

I've got a 351, and an aurora 3000 to work as a secondary if compounds are the only solution to my problem.

Injection pump has a bunch of fuel, super secret squirrel stuff. But please believe me it has the ability to produce if called on. Rpm is a limiting factor with it though, 3100-3300 is about all I will take the risk of with the money I sunk into it and given the builders suggestions, no it isn't on yet so don't reference my recent activities.

I've got a manual transmission so shifting and spooling each shift is an issue.


Suggestions? Money isn't a problem. I've been looking into the switch blade 63's. Thoughts?

My first thought was my 351 with a 4202gtx. BUT I've got not Idea when it comes to pairing turbos, I'm beyond lost.

 

I just replaced my turbo on my Detroit. I will make you a deal on the old one. I have a friend who custom builds turbo's he is good his site is www.evergreenturbo.com give him a call he can help.

 

That super secret squirrel pump I know about is capable of RPM's far higher than 3300. IIRC, it doesn't have the dreaded 4mm camplate. Rather, the 3.2mm possibly. I don't know for certain but you know who or that Canadian genius can tell you . As long as you can keep the volume of fuel to it, I don't see an issue.

And also, The A3K as a secondary below the 351?? The A3K isn't that big, is it?

 

No Aurora is super small. Those are my too.choices for secondaries.

Cam plate is not what you are thinking. I won't spin it past that, not saying it can't.

 

You found my other thread, I'm seriously considering the baylock, seeing as I'd really really like to stay a single. Wonder if I could spin the 66? No idea what it has on the exhaust side.

 

What other thread? Lol Blaylock just announced their new air operated Switchblade turbos for far cheaper than the electronically controlled Switchblade. There's a thread over on Competition Diesel about it.

 

I'd stay away from the Batmo stuff. And probably the Switchblade too. If you're going for a good single, it's hard to beat a GTX series Garett BB.

 

stay away from garrett ball bearing turbos unless you have both a cam AND head porting. They are really prone to surging.

If you want to stay a single, run a 63/68/.85 with a steed speed manifold and external wastegate. the s362/68/.85 with race cover performs unbelievably well too. Algae eater on CF has one on his ppump truck. It spools crazy good and makes over 400hp.

What's your anticipated power level?

If it's creeping to or surpassing 500hp you could get a 64/71/?? with race cover.

Seeing as how I'm going with an aurora 4000 you could wait and see how it performs on my heap if you want. I won't have feedback on it for another 3-4 weeks though. Probably closer to 4 weeks as I'm out of town for work until the 22nd(ish)

Depending on my boost with it, as it is not a wastegated turbo, I may get a ss manifold and e-gate for it eventually so it can run in it's efficiency range.

 

Rick I'm awaiting your Aurora results. The theory is that with the fuel I'm capable of, if I can get air the truck should be past 5. Head work is done, cam I can do. I was also kicking around the idea of a big Gtx and a spool flange. The only reviews I've seen are massive rpm turning p pump guys. All of us brick driving dudes are cheap. The switch blade caught my eye with the awesome boost to drive pressure ratios! I forum talked to the baylock dude but now am a bit uneasy with his lack of knowledge. Not saying he doesn't know his stuff, but when asking questions that pertain to the ve's short comings he fell short. I suppose 99% of ve owners wouldn't be willing to drop the 2,000$ on that chargers so I guess I can't blame him for not educating himself.

After talking with a few buddies over the current situation the baylock is not out of the question but is starting to fall back. The 351 with a big gate going toward a big ball bearing turbo is sounding more appealing. Although compound piping and water lines don't sound like my definition of fun for a weekend.

 

Curious as to why you say this...I know the Stage III BBs surge if you use them on a 1st Gen, but it's because it's the wrong A/R for our application. What Garrett turbos have you seen that surge?

--Eric

 

Stage 3 is the only one I've seen surge, but I've only seen 2 trucks with stage 3's, on has a cam with no head work the other has no cam or head work.

 

I've never ran one personally, but all the surging I've read about with Garrett BBs on 1st gens has been people running Stage 3s off of later model Cummins.

To the OP...I looked again at the new air-operated Blaylock switchblades. They are interesting...if they give you a 30 day money back gaurantee, maybe you should be the guinee pig for us and take them up on it. The boost/drive pressure is impressive for sure.

How many cc's is this pump?


I vote for twins by the way.

 

enough second gen guys have complained about their garretts surging, namely the 3788r, to ignore that they do it. If a second gen 12v surges I'd bet money that a first gen will surge just the same, if not worse. There are other chargers out there that do the job just the same without potential surge issues, and the chargers aren't nearly the expense the garretts are.

As an aside I'd LOVE to see someone turn an he351cw (or s300g) and a s400sx-67 into a compound setup. It would flow plenty of air for all the fuel, even a majorly tweaked 12mm H&R can put out. The s400sx-67 is roughly a 67.5mm inducer compressor wheel, but it flows in the neighborhood of 90 lbs/min. I think you can even get race covers for them.

I think it would be a really fast spooling fun setup. Never tried it of course...

And lastly, get a 188/220 hamilton cam, You won't regret it. I regret not getting that over my 181/210. The difference in spoolup the cam makes, if that's all it did, would be worth getting in my opinion.

Jeff Garmon, a big diesel guy in the states who was a big big skeptic and critic of aftermarket cams gained like 200-250 ft lbs of tq with hamiltons 188/220 cam in his 825 (ish) hp drag truck. If I remember right, he actually lost like 5 or 10 hp with the cam, but the gain in low end tq and spoolup plus what it did for his power curve was pretty crazy.

 

Funny you say something about a 351/67 compound set. I kinda have both of those. I have a hx52 which is a bilit 67......with a 16 or 18 housing.
