I drive my 02 dodge everyday and everywhere but its a sledpuller on the weekends.. Im looking for a good street turbo for the road but still be in the 2.8 class on the weekends. I have bought a huge set of injectors that I cant install til the turbo is on, way to big for stock turbo!! What are some of the turbos you guys run??? I have found some good deals on a bht3b,
s400 "b2" and a used ht60, but im afraid the may have to much lag... what do you guys think?????:shrug:

Anything much bigger than a 64/14 or 64/16 is going to be hard to drive on the street with big sticks. How big of injectors did you buy? They could possibly be too big to daily drive without it being a total pain.

most of the time I just have my 100 hp in but I have been dying to try my new 240's!!!!

What kind of egt's do you see now? have you looked at a head gasket or studs yet? seems like your current setup would make quite a bit of boost.

I have not sled pulled with the 240's cause it will get to hot but the 100hp and 100% fuel on the redline it has hit 1300 almost every pull... I really hope that my head gasket holds for a while longer.. I have hit 50 lbs of boost on every pull this year. If I do a gasket then I will do every all at once-- fire ring and gasket, springs, studs, lifters and a cam!!!

Do you have your wastegate blocked off to hit that kind of boost? If you are only hitting 1300* then there is no way you have enough fuel to make that kind of boost with the gate working. Is the pyro pre or post turbo?

Yeah, those EGT's seem awfully low to be honest with you. I can Hit 1600 unloaded with my drag comp and RV275's, And I also have a bigger exhaust housing than you, if you're still running your stock turbo that is.

Anyways, Those turbos you are talking about are really way too big to run as a single. There are some people that run the Aurora 5000 as a single, but even that isn't very street friendly, and those are smaller than the Ht3b or B2. My friend runs the Aurora 5000 on his CR, and it sucks on the street, even with Big sticks stacked boxes and Dual Cp3's. Like bouncer said, the biggest I would go in a single on a street truck is a 64/14, 66/14 in a CR.

no my wastegate is not blocked off, and my needle is in the elbow. the highest I have hit was 1050 on the redline and i added 250 to 300 to make it right. what I want is to find a big single that will bolt right up to the factory manifold so I can go big for a pull then back to stock my daily driver, same goes for my injectors. 100hp for the steet and 240's for the pulls.

The s300 are going to be the biggest that bolt onto the factory manifold. Anything larger, like an S400, Ht3b, H2E, Aurora 5000, will require a different manifold or a big foot adapter. I would think a variation of the S300 should do quite well for you. If you aren't going to be running this turbo on the street much, a sledpuller 66 would probably be a great choice for you.

Keep in mind anything you use different from your stock charger is going to require a HX40 style downpipe. If you still have a stock exhaust a 4" downpipe is not going to bolt up. Even if you have a 4" aftermarket exhaust you are still going to have to climb under the truck and swap out downpipes everytime you change chargers. IMO it is not worth all of that mess, but your mileage may vary.

Also, I would get that pyro probe out of the exhaust and into the manifold were it belongs. I am still puzzled though how you can get 50psi of boost and not hit more than 1300*, something in this scenario is not adding up.

id look at the 64/14 or 64/16....Am I right or not in that the stock turbo (HX35) is good for only about 35 psi and after that its nothing but hott air??? and the HY is good for even less...so if your hitting 50 psi in 300ft or less, how good are you doing yourself??

so whats the verdict guys? im in the same boat as him. i run a smarty an edge juice w/ attitude. i can blow all the smoke i could want an dont even have injectors yet, but my next step is injectors at turbo t the same time. im looking for a turbo for around town, track, and light to medium towing. as in most trailer weight wont be over 10k total EVER. most of the time im at less than 5k

im wanting to hit 45psi or so, 650 tops, but an effective 50. what sounds right for me?
 
#14 ·
Yes you are right HC its about 32-35psi is the top of the comp. map on the hx35, the hy is pretty similar, but the smaller exhaust housing leads to more heat and higher drive pressures. The few times I've had mine up around 40psi I've been around 1600* and thats running smaller injectors, a box thats not as hot, and an Hx instead of an Hy which is inherently cooler. Unless you have your redline turned down a bit, you should be way higher than that.

I'm not saying you aren't seeing what you're seeing on your pyro, but I think that the change in temps may be a bit greater than you are calculating. I would definitely get that pyro pre turbo, that way you can be sure you aren't going to do damage to your truck. Also getting 50psi out of an Hx or Hy35 is going to have incredibly high driver pressures and will shorten the life of your head gasket considerably.

As for swapping the down pipes, if you have a 4inch exhaust, just use a stack breaker and put a flange on each downpipe, then it will be a simple V-band clamp on the bottom of the DP to switch over, and two bolts or a V-band up top, IMO it won't be that hard, but there is all the other work that goes along with a turbo swap. how often do you hook to the sleds.

650 tops, as in you want 650hp. and I'm assuming effective 500hp and that 50 was a typo. either that or I don't understand what you're getting at.

If you're looking for 650, but you still want decent driving manners and towing ability, I think you're looking for twins. Thats pretty much what I'm shooting for with my truck and why I'm going with twins.

what about a small Aurora? like a 2000 or an HX-40? What about the Edge Jammer turbo anybody ever had or heard good of it? Buddy of mine hits 55 psi with 150 sticks and the Juice w/ Smarty and an HX-40...but that might also be when he pushes that tiny red button...

Yeah, the hx40 is an option but not that great of one. We ran a PDR hotrod 40 with the upgraded shaft on an 01 and it worked alright. It had a HRVP44, Mach 4's and a drag comp. It would hit about 55psi boost, but was at about 1700-1800* running the 1/4mile. It did run the 1/4 in 12.8x but it was very hot and a kind of snappy turbo, it didn't produce smooth power. It didn't have enough air to clean up the amount of fuel we had. So with a Redline and way bigger sticks, it won't provide nearly enough air.

I think the smaller aurora would be in the same boat. We also tried running a Bell USB, which I believe was s300 with a 62mm wheel. It had better street manners than the hx40, but still didn't work great towing, it was a little laggy. I think thats because it had a pretty big exhaust housing.

i mean i want to make 45 psi to 50 of usable boost. apparently a hx35 cant make effective boost after 35 as it is hot air. i am not worried about hp numbers, just wanna know what turbo to run for street/track combo with some medium tolight towing. wil be running juice, smarty, my fass and then the new turbo and will decide on injectors accordingly, but thinking only 75 to 100 injectors tops.

Ok, gotcha. I thought you were shooting for High horsepower numbers too, in which case the avenue of streetable turbos gets very narrow. A lot of people seem to be happy with HTT's 62 series. That is very similar to the USB we ran, they are based off the same turbo and run the same size comp wheel too. The new 71mm exhaust turbine that Htt sells is supposed to help with spool up, which was the main thing we didn't like about the USB, but we also had a 16cm ex. housing on there. I think a 62/13 sounds like a great set up, but I haven't really been around one yet. Talk to Bouncer, he runs one on his truck. If you don't want to shell out the money for the stainless steel 13cm housing, the 62/12 with the 66mm ex. turbine would probably be a good bet.

the 62/16 was a good turbo at the track, but towing around 8k, in hilly to mountainous terrain with big sticks, it would get really hot down low, and when it would spool, the truck didn't want to go as slow as the roads required. So it really just didn't have the right manners for what we were trying to use it for. Other than that, I would say it was a good turbo.

Sorry that was long winded. In short I think the smaller ex. housing would've improved drivability and made it a nice turbo.

The 62/13 stainless is a awesome turbo. Any of the stainless turbos are extremely nice. Not only does it have that big 71mm exhaust wheel in there, the stainless really helps retian the heat and transfers it to useable energy to help the spool up.

What is nice about the HTT HTB series is all oif their turbos are upgradeable to anything the sell. So if you don't have the cash for the stainless now, you could always upgrade your charger later down the road.

I know the 62/13 I am running now is good for 575hp. Another really nice feature is the dual port wastegate. Where you set the boost level it will just about stay there and protect your engine.

as an added bonus I bet that stainless looks GOOD too doesn't it???

Actually is is not polished, so people can not tell. If you polish it the heat makes it turn gold. There is a guy on TDR that polished his and calls it the Golden Nugget. It looks sweet. :Thumbup:
