Superseded is a better term for the original series. The new pumps in production at Fass are the Signature series. Fass has a strong policy against discounts on their products, but superseded discontinued products are allowed to be discounted so we are selling them for a lower price

I have at least 2x pallets of the original FASS pumps and have them on sale on our site (discontinued = no MAP). The signature series makes sense if you have a late model diesel as they are quieter. Not convinced the value is there for a VP or 3rd gen or even early 4th gen truck.

We still do the rental for those who cannot find anyone local who can help. Better than going to the dealership. https://www.dieselautopower.com/smarty-s-03-rental-sr-s03a

nice find for the truck. I recently sold my 6spd as well. 2wd in the snow is not practical.

I noticed the 2010-2012 is not in this link. I have asked our web guy to update it today. https://www.dieselautopower.com/catalogsearch/result/index/?brand=436&q=cummins+tuner+ With emissions becoming more enforced and tuning with emissions present becoming better its a good idea to look at custom tuning with emissions present tuning.

Emissions present custom tuning is a good option as well. You can turn off the EGR and Regens go down to almost never. We offer them and would recommend many look this direction to avoid future headaches with registration, risk of fines etc.

You are welcome

A hx35/ super B special (64/71/14 .80 gated) is a little small for a primary, but you can make it work. Peak HP would be lowered to about 450-500HP, but spool up would be very fast. The BD towing kit is 57/65/14 over a 66/74 with a larger turbine housing like 1.10AR and rated for for about 550HP max. Ironically the superB special is rated at about 600HP max as a single turbo, but is not very happy towing at high elevations.

Nozzles should last much longer than 7500km. I looked up your order and saw that you bought nozzles. Contact Mitch and we can get something worked out for you.

I will send @Quadzilla Marco a notice.

60/s475 should be good for 600-700HP. You should be fine with a set of 7x.014 sac for about $600. S475 and compound piping is under $2000 for the set.

Thank you @Mopar1973Man I responded to his PM

It could be related. Low pressure could cause problems for sure for higher end power. Check to see if the snubber is installed and if its a needle valve that it is open.

Thank you. Would you like to mention a specific sales/tech that helped you?

he351cw 60mm is the same wheel (or its previous part #) is most often used to build 35/40

he351 is 60mm, same as hxsuper40

Sorry to hear about your turbo. Unfortunately I do not think the he341 will work.... iirc its 58mm and your hx35 is 54mm or 56mm.

62/73.4 will fit in your T4 .91 and would be less expensive as you would not need a turbine housing (save about $160, or $210 if its hx40 cut) Would be better to do a 62/68/.83 T4 for the faster spool up, and you can sell the 66mm with a housing if you decide you want to keep the 62mm. Felix can get a discount on the parts for you.

Correct, It will help top end power. Low end spool up will be slightly inhibited as you will lose some of the pulsing of the twin volute. Reducing back pressure is important. 1.2psi back pressure or lower to 1.0psi Boost otherwise you are leaving HPon the table. Running a waste gate or getting a larger turbine wheel or housing will reduce back pressure. You add more exhaust gasses/ from fuel/ boost/ higher RPM and it gets constricted. The stock hx35 is about 58mm exducer on the turbine (25.4mm = 1") =2.3" figure you have a 7mm shaft, + hub (lets say 2x 3mm=6mm) and a number of blades on the shaft. So with bad math we get to about 45mm with blades in the way. So thats about 1.8" with blades. Enter the wastegated housing... 17mm to 22mm are common sizes, S300 turbos usually have 2 of them. So with the wrong size turbine/wastegate/ turbine housing its common to have over boost (less efficient), over speed of the compressor wheel (reduced life from centripetal forces on the wheel = deformation, oiling problems, less efficient, more wear), and restriction to the flow of the exhaust). Its about flow in and out of the engine (boost does help). Think of a water hose. Low pressure... high flow. Kink the hose and you get 40-60psi.... and no flow. There is a sweet spot and a good place to start is 1.2back pressure to 1.0psi boost. No one would recommend ditching a 3" or 4" exhaust and putting a 2" exhaust on just to overspeed the turbo, make it less efficient and wear out your turbo faster to create greater pumping losses in HP and a pressureized engine/box). But that is what blosking off the wastegate can do for you if you do not know your boost /drive pressure ratio. Who has measured their back pressure/ drive pressure and lowered their boost to bring back pressure to a more beneficial #? Please post your experience. Manimalmother, Looks like you did a nice job. The more you pull out of that center divider the more the sides can equalize pressure and gate from both sides, but the more it disrupts the pulsing and therefore the spooling of the turbine. If more power is your goal do aggressive machining as pictured. If you want a small reduction in drive pressure/ with less reduction in spool go milder. Again the machine work looks great.

Without a compressor MAP and turbine flow its hard to do a side by side comparison Looks like a good turbo and hope it works well for you. Something to be said for modifying an hx35 or he351 and doing it different. I am sure there are benefits to both a custom hx35 and sxe turbo. FYI I have seen maps for 60mm compressors that varied from 56lbs/second to about 68lbs of flow. Those of you who have sized a prop for a boat may be familiar with more of the differences.... blades, pitch, inducer (usually the only one measured) and exducer diameter, hieght of the wheel, tip extension, extended tip, and the AR of the compressor. the 66mm SXe with larger compressor AR gained about 9lbs of flow by going to the larger housing. SXE 64.5/88 exducer outflows the older design 66/91 exducer. Maybe a turbo engineer or someone who is more familiar is reading and can offer details and pictures...

HI, We spoke in person at the event in November. You have a very clean 2nd gen. Your truck looks great! It was suggested that you could go with the custom tuning first as it was free. Smaller top turbo (62mm) and gear change would both make the truck more responsive. When we spoke you did not want to have your cruising characteristics modified. Heck try/borrow a set of stock sized tires/rims (if you do not have a 10 lug conversion) You can see with less than 1 hour work how much more responsive it would be if you made some changes.

Let us know how you like the changes.

Make sure you switch to an open/ non divided gasket on the manifold. or drill at 45* and keep the standard gasket.

We set up all of our P7100 pumps to higher pressures. stock is 260 BAR, we set them closer to 280BAR for performance sets.
