Would like Turbo advice

[JEmery]

Hello all!

I recently decided to take my truck to the next level, my current mods should be in my sig. Truck is used mostly as a daily driver, occasional light towing (around 9,000 Lbs) and after I get the transmission I would like try out some sled pulling. So... .



Today I ordered a DTT trans and a TST. Next will be a new turbo, I think that I will just run a single. Looking for around 500 HP. I wanted a SP 66, but have heard they have to much lag for around town. Is anyone running ATS's variable geometry turbo? It sounds like a good concept. I have read a ton of posts about turbos, but I am still undecided.



I Need to have all this stuff done by the 22nd of April for a local dyno days!



Thanks for your help!



Jeff

I have a 66mm turbo, and it is fine around town. BUT you must ge the TST twins program, or it will be super laggy feeling



I recommend finding some local 3rd gens with turbo and see for yourself. Spool up is always by opinion it seems

industrial injection is the way to go. pm me if interested :-laf

The way to go?

PLease, wade - Can you expand on that?



I would like to know that benefits of the II 66mm turbo over the 66mm turbo from HTT...



Ohh and Facts only, no gray area sales pitch like "faster spoolup, more hp" - I mean stuff like shaft size, special porting, fancy wheels, fancy WG - Stuff that is physical difference



Thanks! :-laf :-laf :-laf :-laf

BTW - The HTT Spedpuller held together on a 72psi dyno run at 1055hp by Jeff Garmon - See HTT's website for details.

Honestly I think they are equally great turbos, But again if you can prove otherwise, It would be interesting to know...



PS - Wade your coming to INDY right, For diesel nationals? It would be cool, especially if you have a STAGE 2 Cp3 by then!

i guess you right the facts is what you need to see but all i can say is what it has done for me---i can't release my dyno #'s yet to show you, and yes if my project is complete you will see me and others associated w/ me at the nationals--across the country, w/ alot more than has been discussed here on TDR. :--) in my oppinion II is the way to go. thanks :-laf

go to www.htturbo.com they offer great turbos call them tell them what you have and what you want it to do

I also would like some info from guys running these 2 turbos my poor little super b just not enough now with the injectors but I do alot of stop an go driving around town an don't want nothing real laggy.

I have a Super 62 and I agree, I love this thing. Sure I haven't ran anythng else "wished I had the money to compare turbo's" and it is a 62 not a 66, but the way the truck has been running/brething so much easier, I couldn't be happier. I have a picture of the turbo, PM me and I'll send you the pic... You can see it a stout turbo... :-laf I'm not trying to step on any toes and say that the SPS 62 and 66 is better than HTT, but I am saying that industrail injection treated me really good, that's all.

if you have the super b, get the twins upgrade. that setup would outperform any available single for our ctds

I'm down sizing my sps 66 to a sps 62. Too laggy on the bottom end. I miss the punch the truck used to have. Yeah, it screams on the upper rpm, but I think the fat mid range would make it more driveable.

 

[mattymac]

I love my SPS 66 but I wouldnt recomend any 66mm charger for towing! They will surge, go with a 62 for towing. I dont think my 66 is laggy by any means and im still running the single's program on the TST. I may downsize to a 62 because of the surging while towing heavy (6-10K). Tomey, I to agree that they are both awesome chargers but check with Jim Fulmer on the diffrences between the two (II and HTT).

 

[zstroken]

I think they both have great chargers, but I think the HTT stuff is the best bang for the buck.

 

[RMalone]

I will vouch for the quality of II. And HTT has a reputation that is above reproach. That said a 66 with TST standard is acceptable around town, but definately spools slower than stock. Sure from 12 to 45lb it is VERY fast, but getting to 12lbs can be irritating. If you are the kind of guy that likes to drive aggressive in traffic and wants power "right now" a 66 might not make you happy unless you have twins program and/or injectors.

First of all Sled pulling and light towing are two different things. However the Super Phat Shaft 62 has made some very impressive hp numbers. The Super Phat Shaft 62 is very fast spooling. It also can make good hp for sled pulling. If you are very competitive and sled pulling is something that's serious with you then a Super Phat Shaft 66 is a good choice. Then again you may want to go for a Silver Bullet. It spools faster than a 66 and the air it delivers is something special. We don't just put in larger comp. wheels, we upgrade the turbine side. This allows the exhaust drive pressure to be very low. This helps drop EGT's and increases turbine/comp. speed which makes more air. We ran our truck on the dyno about a week and a half ago. We were at 719hp when the stock head gasket blew. We were making 75-76 psi and we had very little smoke. We are now ready with a oringed head and bigger injectors etc. to keep going up. We will show the results when we are finished. This won't be done with a ton of nitrous and will be done on diesel only. After that we will put our twins on and continue.

You may want to try a modified CP3 pump and some Stage 3 injectors.

 

[Diesel Power]

hey brett,

you need to fix or replace the transmission in your sig???? Oo. :-laf :-laf :-laf

 

[CHolman]

I know that this is a little off the subject, but I had major surging issues with the stock turbo and the BDDL at 90hp. The stock turbo would be real laggy until about 7 or 8 psi and then shoot up to about 20 psi like nothing and peak at 28 psi. Don't ask me why, because the size of the impeller was way small, couldn't believe my eye's when I saw how small it was. :--) Looks like a damn T-4 Turbo. Well I put the ATS arch flow manifold on about 4 days before the SPS 62 and the boost built a lot smoother and I no longer had the right off the line lag, like I had before. "I have the NV5600 6 speed"... I "think"<--- A Arch flow manifold would help you guy's out that have a 66 and have surging issue's. Now that I have the ATS exhaust, ATS arch Flow and SPS 62, she's smooooth... . :-laf Just giving you my 0. 02 worth.

Sorry Barry I should have already done that.
