I broke my front driveshaft on my 2016 2500. It was during a boosted launch. Do they make a stronger shaft or just get another stocker and take it easy?

I ran 11.9 out of a pusher compound with an S480. Now I wanted to build something for around 1000hp. I really enjoy and drive my truck so I wanted something streetable but fast. I already bent my rods 2 years about so I have a built motor with a Hamilton Hot Street Cam and a girdle. I did an...

It seems like it could be a good turbo. It's definitely high tech. I wanna switch out my secondary turbo. My primary is a S480. You can get this turbo setup as a twin scroll housing. I want quick spool but don't know if a 1.05Ar housing will be too small. I do have a wastegate setup to relieve...

I am building a new compound setup for my 2016 2500. I need the wastegated T4 manifold. What I can't decide is should I use the straight flange or the angled? Do the angled flanges work okay with the wastegate? It seems they would work better with the angled flanges? I plan on mounting my S480...

I wasn't sure where to post this but I purchased a CA conversions kit a few months ago and the first transmission lasted 2k and I had to send it back to them to fix. I had to pay for it because they said because I added a cam it messed with their computer they use and caused it to fail. Now 1k...

So I purchased an Allison Conversion from CA Conversions for my 2016 2500. I use my truck to pull my 8k camper. I do like to have fun with this but it's my 3rd truck so I don't use it a ton but do like to drive fast when I can. I thought the Allison transmissions was going to be way better than...

Any advantage to running a cometic head gasket or just stick with a stocker? The head is O ringed.

Just thought I would post in a forum that hasn't had anything new for a while. Let me know if you got any updates on my head. Sorry I wasn't quiet ready to commit to the Hamilton block yet. I am going to see how I like my setup and go from there.

I got the 12mm Cummins girdle. I didnt get any 12 point nuts in the box other then the 2 for the rear. Am I really supposed to use just the nylock nuts to hold down the main caps. All the videos look like I should have some 12 point nuts before I install the nylock nuts but the instructions...

DDP sells an upgraded 8.3 pump but its not in stock but then other sites sell an oil pump for $150 that fits the 6.7 and the 8.3 so are they the same pump?

I was going to do rods and basic arp studs but is it needed at that power level to do anything more, like girdle or bigger studs?

I have a 2016 Cummins that I just bent a rod on. I am Allison swapped so my drivetrain is good and I am looking to build a setup to get me around 1300hp when turned up. I think turbo wise I should possibly be able to get there. For fueling I have dual CP3's and 150% injectors. I would love to...

Just wondering if anyone is running this? Seems a longer rod would be great and a lighter piston even better. I also know steel expands less then aluminum at same temp so maybe run a tighter wall clearance. Anyone have any experience with these on the street around 1300hp.

I have been running an S480 that I added to my stock HE351vgt turbo. I like the exhaust brake and the looks of the big turbo on top. I know people can make 1000hp on a S480 but I know I can't put that drive pressure through the stock turbo so I am going to add a wastegate or 2. Has anyone ever...

So I currently ordered the full Allison conversion from CA and I am having them build my transmission for 1000hp. I currently run a billet S480 over stock. I would like to keep trans brake but is it possible to get 1000hp? Does stock turbo become too much of a restriction? Can that be bypassed...

For the people who have done the swap did you use the CA conversions kit? What is the best year for transmission to get? Anything you didnt like about the swap?

Just looking for a good site for using warp. I am mainly wondering some conversions for my 5in intake tube and how to scale the MAF properly.

I am building a compound setup for my 4th gen. I just got a couple questions now and will probably have more. I am currently removing EGR and what is the best way to remove the hoses to the cooler and just delete all the coolant pipes or reroute them. I was going to build my hotside up pipe to...
