Stage 4 CRP Turbos Revisted (ZFGRACING)

[RMB_Ryan]

Here is one I did on e85 in 2019. E85 was 180 hp over stock and 80 over 93 tune. I did his brothers Expedition with the exact same mods even down to the brand and picked up over 200 wheel horsepower thanks to the extra half a point of compression the none ho has.

Now in terms of longevity those 2 levels are pretty sustainable again as long as the torque is well-managed and a whole host of variables. For example if your guys's oil is even a little tiny but under full when you launch you are going to see an oil pressure drop and that oil pressure drop is going to kill your bearings and the lower you are at oil the longer that oil pressure drop is going to last for in terms of first gear and second gear and sometimes into third gear and then it's all over [emoji38]. A good side note is pretty much all of my fast F150 guys and even Explorer St guys are running a half quart over full. Totally different discussion I'm getting sidetracked.

Either way 180-200 hp over stock on stock turbos is where you need to stop sometimes less depending on other factors. What normally starts to happen if you try to push Beyond it and you can push Beyond it because there is still turbo left but what's going to happen is you're going to start seeing head gasket failures (or worse) from excessive back pressure. In my opinion if you keeping the peak torque the same you are safer making 550 hp on stage 4s then you are making 530 on stock turbos.

That being said you aren't going increase power by 200 hp and still get 200,000 miles out of of a motor. You decreasing the longevity of your motor and increasing the chance of a catastrophic event. By how much really depends. And it also depends on how well you take care of it if you're running 6 7000 miles on an oil change and using crappy oil well you know what's going to happen.

180 gains we see 85% come in with blown head gaskets and broken pistons

Factual and if you haven’t seen it because tearing them down is not your thing as 6-10 are done weekly

Highly suggest never pushing 575 hp or close to 600. 98 percent of trans are smoked once removed the converter it shows the story

On an old I modified pan, 200 rwhp your turbos are done at best so timing is how you get there and no emap sensor on each bank monitoring back pressure 100% gasket failure


We have turbo upgrade stock location that produced over 150rwhp over crp and made by a company who provides manifolds that are not flowing just under curve but 60-100cfm over crp with way more lb/min air and have data to show which also factually provides far less and safer back pressure

Many havepulled and seen Nader 50hp gains ajd Gearhead provides more rwhp than crp woth stock manifokds

There is one oil pan at 295 and 37-56 dollars shipping which is machined and addresses any of the so-called issues of stock oil pans which we haven’t ever seen.

This is increasing the sump and oil capacity by 2-4.5 quarts with trap doors and we have them in our machine being made now, and the only fix unless $14-15,900 is not cheap ajd can swing the cost and truest want a proper oiling system with true scavenging

Not one oil pan oem or alike is comparable to our cheapest pan all aluminum as it is machined and the photo posted is the only other than dry sump will adress all issues and properly fix your issue if you want it fixed

Available as quick as needed and oring sealed

Didn't think you were ready to release that yet so I wasn't going to say anything but yes this is definitely the solution. Here is what to look for in the data log.

Going to have to highly disagree with that post I know you don't have the data because I know which customers you're referring to and I know who the tuners were. I also have exhaust manifold pressure on the turbos not just some tuner who didn't know what they were doing data. We are making 7-8 lbm/ min more at less e map than the stock turbos.

Can I have two 100% disagree with you on this one as well and you know that we're always going to disagree about how much horsepower is a stock motor can handle. But here's the bottom line you're not tearing down Motors that I've tuned with the exception of the R&D projects. And you know we've had many discussions on the tuners that are tuning the motors that you are tearing down and what their shortcomings are.

Virtually every single every single customer of mine that is running E85 is running at that power level. As long as the torque is staying under 580-600 foot pounds it's going to be just fine.

The only failures we have seen on E85 is when we've tried to get too greedy with the stock turbos, but I've learned where the line is. We've had a total of 3 head gasket failure is on two trucks, and one random broken skirt which may or may not have been a result of some ridiculous rev-limiter action.

I've definitely seen a handful of bearing failures in my customers as well and I'm 99% confident that it has to do with the above oil pan situation, as that has happened across all power levels and all fuels.

That all being said if you want to make 600 horsepower and never have to worry about it you should absolutely buy a short block from RMB the more built Motors we have in this world the better.

Cheers.

Rereading.

oh Im aware. I cant wait to see what you put down on the dyno and on the track. Just saying I think it would be cool to see a $2k modded raptor match the TRX on screen.

I offered them my goose stage 2 but they didn’t respond. It has to say 5 star for them to consider I guess.
