Engine/Transmission (1994 - 1998) Turbo/Injectors

[Buck88]

Well guys, getting my auto built soon, then comes the fun stuff. I'm thinking a HTT HTB2 64/14, dynomite diesel stage 4's, Lazer cut DV's, and maybe water meth. Is this a good setup? What kind of numbers will it put down? Is that turbo going to be to laggy? Thanks, Buck

I think for the ammount of fuel you are planning to throw at it, you will want a larger turbo.



I'm not familiar with the HTT turbos, but I know the Phat Shaft turbos spool Very quickly. Even the SPS66 spools about like an HX40.

I agree with Josh. I think you will want to go with the a larger turbo, unless your doing lots of towing. I would hold off on the DV too, until you see where your at. The DDP4's move some fuel. You can always install them later. What are you planning on doing with the truck? How much Power do you want??

what altitude do you run at? put a 62/14 on a 98 12v that lives @6000 and its not happy. We have the DDP4's, #10 plate, timing and starwheel adjusted all over the place . Its pretty happy @ lower elevation but not @ altitudes above 4500.

 

[Buck88]

Well, I never tow. The truck is strictly for stompin' on duramaxes. I live in So. Cal, at I would say less than 3000 feet. I originally wanted to throw a 66 at it, but people told me that it would take forever to spool. I'm open to any suggestions. Thanks a lot for the feedback. - Buck

From what i have been told the sps66 will spool faster a hx40 and make some great power.

I have driven an HTB2 62, and 66. Couldn't tell much of a difference in spool up. Especially if you have the fuel. The SP66 I used to have would lite really well at about 16-1700 rpm.

The 64/14 isn't here yet, but I think you'll be just fine with it. Particularly since you don't tow. Minus the #6 plate, I have a similar setup for what you are looking at doing (check my sig). My 40 is a perfect match, IF I don't tow. Have EGT problems towing over 55 mph, unless the ambient temp is under 50* and no headwind. Have enough power to run as fast as I want, but the EGTs hold me back, most of the time. Even with a small enclosed trailer that probably doesn't even weigh 4k loaded.

Mileage Drop?

I've heard that running a 66 will drop your mileage 2-3 mpg over a 64. Is this true? I imagine that mileage would drop when driving hard, but no difference when trying to get the best mpg. Thanks - Buck

 

[Smokin_Monster]

Turbo size especially comparing a 64 to 66 will not affect milage. Only your driving habits. The only other thing that I have ever found affect my mileage was tire size, because it changes your rpm vs. mph. Turbos will not.

From what i have been told the sps66 will spool faster a hx40 and make some great power.

After running a SPS62 and knowing how that drives and spools, I cannot imagine a SPS66 spools as fast as an HX40?

 

[TJarecke]

You could go with a Quick Diesel 64. It should cool a little better than the 64/14 and you wouldn't have to go quite as big as the 66.

I would agree on the DVs. Bigger isn't always better if you can't move the fuel. I would try it without the DVs and then look into them down the road if you still think you need them.

I'm running a nearly identical setup with a Pro Street 66 and a tweaked (not tuned) 180 pump. You'll want the extra air. I have no problem pegging the pyro with the 66 charger.

If you can live with a bit slower spoolup, get the Pro Street 66. I like it better than the Sled Puller 66.

 

[wildmanben]

Is anyone running the Pro Street 66 or Quick Diesel 64 on a 5sp? I am stuck between them and wondering if anyone has experience with either.

 

[Buck88]

Whats the difference between the Sled Puller and the Pro Street? Bobcat, whats your mileage like with that charger?

From 0-10 psi it is a little slower and maybe a tad slower from 10-20 but after that you can take the 40 and throw it away because it not in the same world.



In extreme cases like mine ask yourself how well a 40 would do at 800 hp taking a slap to 65 psi... ... ... ..... BOOM!

Turbine section, has a larger turbine wheel, and the throat of the exhaust housing is slightly larger. The larger turbine wheel increases the shaft speed, and also offers less backpressure. It will start to spool at a slighly higer RPM than the standard 14, but once it starts to spool it will spool much faster. It is a good charger. I never had any issues with surging on the standard housings, and thought they were a little more street friendly since they would spool sooner, but the Low back pressure wheel series(high tech, super phat shaft) will cool better and move more air on top. Both chargers are very street able.

I agree that after 15-20 psi the SPS 62, and I'm sure the 66, wil blow an HX40 away. Shoot from 15 psi on up the SPS 62 was a screamer. It was just my experience that from 0 -15 psi the 40 seems considerably more responsive than the SPS 62.

you need a 66 if you even think about putting stage 4 injectors in your truck, i have stage 3's, fully cut dv's and a 100 plate, and i can still see 1500 deg, and thats at 52psi!! stage 4's will put alot of fuel out, as you know the highest hp 12v in the country is running those injectors. by the way what do you plan on doing to you stock auto? your going to ned a full biliet transmission to hold the kind of power your going to be making. just a thought...

I beg to differ on that. I saw a handful of trucks in shelbyville and cynthinana that were putting down some power and they weren't using the DDP4's. The DDP4's are a great injector though and will move some fuel.
