A 62/65/13 will be better for performance. But, the hx40 and Super B will both be better chargers for towing in my opinion and still allow good power. Heck, McMopar(i think) ran 12's with an HX40. So did John Porterfield. And they both towed. The 57mm S300G(super B) is nothing like the stock compressor on our trucks. Its only 1mm bigger, but it is designed to flow much better. The HX40 compressor is the same design, just bigger by 4mm if you go with the 60mm, which will also outflow a stock charger. Not to mention they both have 4 inch exhaust outlets on them.

hy35w is a 54/58/9cm 01 and 02 autos
hx35w is a 56/58/12cm 94.5-98.5
hx35w is 54/58/12cm 98.5-00 & 01-02 Manual
he341 is ??/58/9cm 03-04.5
he351cw is 60/58/9cm 04.5-07.5 5.9
he351ve is 60/71-60/3cm-26cm variable 07.5-current 6.7

HX40 has different sizes most common is a 58/65 or a 60/65 with whatever size turbine housing you want. HX40 has probably 15 different comp. wheels you can run on it.

I appreciate what you are saying. However, reality is that the chargers you are recommending rarely work as well as you think they do. Both the S300G and the HX40 offer little help for actual charge air help. The benefit to both of these chargers is the swap to the looser turbine sides. I can't tell you how many guys have bought the Super B / S300G and HX40' due to cost and have been grossly let down by the unacceptable EGTs.

Too many focus on airflow and not on the quality of the air that is being moved. The best solution would be a set of towing twins for his application, but gearing will still have a huge effect on the ability of any turbocharging solution.

He would do just fine with a HX40 60/65/14. They have been dynoed to 600+ HP. People dont like the HX40 because the shafts are weak and have a tendency to snap when the turbo gets barked.
If you can score an HX40 60/65/14 for cheap I would sayy go for it.
You can get a brand new HX40/35 with a non-wastegated 14cm housing for $795.00.

Yea the buddy I might be able to get it from already mod'd it to fit a 2nd gen and will give me a good deal for sure he said.. around 5ish.
But ultimatly I want a 62/65/14 so thats what got me thinkin about custom twins.
However, being dead set on the 62, if a custom twin set with those two chargers wont be that great.. Im fine with holdin off till 62 and new sticks come along.

Thanks for your debatin guys. Great info all around, I appreciate it.

I'm building a twin set now too.
62/68/14 with a super 62 wheel and a race cover from Engineered Diesel.
Bottom turbo will be the S475 I have in the garage.
Should put down 700+hp.

I'm getting tired of playing around with big singles. My new camper doesnt like them too much.

Small twins are great for towing. I'm very satisfied with the he351 over 3b. They light pretty quick and cool the 200 horse injectors with the adrenaline on setting 2. On real long hills grossing 24,000 it will climb to 1300 on the pyro but just kicking out of o.d. cures that. For a budget set of turbos the he351 is hard to beat for the little turbo. On the setting above it will make around 40 to 45 lbs. of boost with the he set on around 30 lbs.
Good luck on your choice.

You are right. EGT's will be higher than a 62mm charger in a performance only application. But, if he tows a lot, the 62mm chargers are a little big, and they like to run hot cruising with a load, especially when you hit a hill. Like i said, in a performance only truck, then a 62mm charger would be great. But a 62mm charger wont tow as good EGT wise as an HX40 or S300G.

Personally, id rather be a touch small on the charger than a touch big. With much fuel, a 62mm wont keep EGT's down enough more than an S300G or HX40 to matter anyways. It will just add more power.

Honestly, for strictly towing, other than twins, I think its hard to beat the stock HX35. They spool quick, and keep EGT's down good.

i dont tow really heavy, usually arround 5-7k . I have been running the 62/71/13ss for the last couple years and love it. makes good power for a smaller single, i can hit 1500 deg by the end of a 1/4 track but usually stays well under 1000 towing my boat arround with a five speed. It gets my vote in the 5spd anywhys not sure about the auto.

Don't get me started. I don't know whether to laugh or cry at the 60%+ markup people are lining up to give to a shop when they've done ZERO engineering-- just parts swapping, and "hey, let's try this" approaches.

My rant on this is available via search.

Check your wastegate pucks to make sure they are properly sealing. There have been ALOT of problems with the SS housings. HTT is suppossed to have a "fix" for them.

Heres some reading on them.
