I live at 6400 elevation and pull camper to 11000 at times. I thought the super B would cool and spool say 380 hp pullin a trailer. Now I am hearing they dont spool tell 1800 rpm. I know I cannot put mach 2 injectors with a quadzilla without a turbo. I dont want lag and I dont want twins and dont want a hot running truck. Is there something out there for the bill?

Your probably thinking of the super B Special that doesn't spool until 1800rpm. I have a special and have to get rid of it because I can't drive on the highway unloaded well with it at all. I have 2 other friends that have the special, and regular Super B. Both of them have them on 24v's and the one with the special had to add water/meth to keep it cool while towing and still be cautious of his egt's, and the one with the regular super B loves his but wants more power. I also live at a higher elevation (5280). I would think you would be fine with a regular super B. The special is just VERY laggy

For 375-400, why not just run the stocker? It will be hot on the top end, but will get to the power you are looking for. The next best would be something like the Super B/S300G. Any turbo thats bigger is gonna spool slower. You might want to look at something like a Garrett GT3782R. Ball bearing turbos spool up quicker than journal bearing, but cost a fair bit more.

Look at the late model he351.

a 62 is what youd be looking for. add that with a 13ss exhausthousing and a quick spool manifold you shouldnt have any problems with that thing spooling slow

I really like the hybrid on my truck. It can get warm with a strong headwind when pulling a trailer though.

While my turbo is a 14 housing, not a 13, compared to the stock turbo, its a dog on the low end. Quick spooling to some, but not a quick spool turbo, especially for 400hp.

How is the phat shaft 62 with 12cm wastegate for spool up compared to the super b. Which is better for early spool up?

Big Blue24

The super B is rated for 425 Hp and can be pushed to 450. It's a 57 mm compressor with a 65mm exhaust turbine wheel.

A phat shaft is good for 525 Hp and can be pushed to 600. It's a 62mm compressor with a 65mm exhaust turbine wheel.

The super B will spool faster but will leave you wanting more power if you plan to exceed 450.

The HE351cw is good for 500 HP and can be pushed to 525+ with the correct fueling mods/tuning. It has a 60mm compressor, 58-60mm turbine wheel, and a tight fast spooling 9cm exhaust housing. This will be the fastest spooling and cheapest turbo but you will have to do some parts scrounging and or light fab work for the exhaust downpipe.


Your truck has an HY35 which is the fastest spooling stock turbo for dodge trucks so anything else will be a little slower but offer superior EGT control. This turbo can support 350HP and be pushed to 400 with the correct fueling and tuning modifications.

dont forget though how much fuel u put in at a certain time has a lot to do with it. Right now my trucks acting like a bit of a dog down low because i dont have it tuned quite right yet once i switched fuel plates (trying a #5). but its definetly better on top end now(which is wat i wanted).

could be bias but i felt my gt3782r pulled just as hard or better in the low end. but i have no heavy pulling experience

Bigblue, How do you like your 3rd gen turbo, I have a buddy that put one in his and likes it but i havent asked him enough about it yet. Whats the cost of it compared to a super B or something similiar? How many lbs boost?

Big Blue24

I bought mine for $245 shipped to my door. Total cost for misc parts to connect the exhaust and cold pipe was less than $150.
