holset super hx40
 

So I know a guy that's wanting to run one of these turbos on his truck but he's unsure if the 16cm exhaust housing would be too laggy to tow an daily drive with it. He's wanting to run 100horse injectors an edge juice an a Hamilton towing cam. Would this turbo be good for his needs he only tows an daily drives with the truck.

If the turbo is a good price go for it. Go with 125HP injectors. Its a little laggier than a 62/65 but its a solid turbo and has the better 60mm compressor wheel and the 16cm housing. Keep in mind you can get a super B turbo (that will spool faster and will almost support as much HP) for about $1000.

Quadzilla adrenaline is back. Cam is not really necessary.

Ok thanks Jkidd. Would a 63/68 turbo be suitable for towing an dd with the setup I mentioned in the first post an what size exhaust housing would you recommend?

I've been running that turbo on my 1st Gen with 5x12's for a few years now and it works great - no spool or lag issue whatsoever.

you can tow with a 63/68 or better is the 62FMW. I will send you a link to some of our combo deals.

OK an what would you recommend for a good towing build ie- injector size chip/programmer?

Adrenaline + FMW62 + 7x.010sac and some head studs. 550HP and tows well.

The 7x.010 is 175hp correct?

How does that super B turbo compare with the stock HX35 (I think) on my 01? Would it spool faster? Would it install without mods to other components?

Super B is a better turbo than the HX35. It wont spool as fast but it will support more air and higher boost pressures.

I'd Prefer a turbo that would spool faster than stock. I think what I'd need to get what i want would be a twin setup with a smaller or stock sized turbo fed by a larger turbo. If I understand twins normally a larger turbo pulls in air from the air cleaner, then feeds it into the smaller turbo and that feeds it to the intercooler and then the engine. The exhaust goes into the smaller turbo then to the larger turbo and finally out the down pipe. Is that correct?

Would a stock sized but more modern turbo, maybe a ball bearing with a more efficient set of wheels or more modern design maybe spool faster and give more ultimate pressure than my stock 15 year old turbo? Does anyone here know about that kind of turbo? Oh and that 15 year old turbocharger has been feeding the truck for 171,000+ miles. Might be a bit worn by now, ya think?

Thanks to everyone and anyone who can help.

You could use a HX35/S475 combo. I believe its good for about 500hp. But a set of compounds setup to work with your stock turbo will run about $2500-3000.

Yeah, My intentions are probably very different from nearly everyone else. I'm not interested in peak horsepower that requires me to spin the engine at high rpm to get it. I don't drag race, nor do I sled pull. I am interested in torque and low egt for cruising down the highway in top gear and nice and quiet. So I could probably be happy with a turbo set that would spool very quickly and not smoke when I have to get on the freeway and run out of fuel at 2800 but would pull strongly at 2,000 rpm up a grade. I don't need the high rpm capability since I will probably never exceed that rpm except by accident. When I'm not towing I typically shift at 1600 or less unless I'm on an on ramp. Then I might go to 2K. Towing I up shift at 2500. If I hit a grade and it won't pull without excess egt I downshift about 1700. My owner's manual says not to pull heavy loads below 1600 rpm in 6th. So I give that a bit of leeway. I'm that guy people used to refer to as a "grandpa" driver.
