Ram50

the video

Hey, I thought you all might enjoy watching the video of the turbo explosion. This thing took 2 hrs to upload to photo bucket. Their has to be a better way.

Anyhow, you can see the intake (grid heater) gasket completely fail as soon as the nitrous comes on. She was still on a heck of a pass. That left front wheel wasn't touching when she was under power.

I had talked the MRA folks into letting us run Outlaw Pro Stock. This class is for aluminum headed, dual carbed, nitrous injected, and unlimited cubic inches. I can only speculate on the time she would have run. The track was 160' long and the winner of the class ran a 2.5? something. I think we may have turned a few heads. lol

Sucker looked like it was on a mission! Good to see you playing with it on a regular basis. X2 on the YouTube thing.
 
I've neglected the little truck for a while, but, I'm back on track. The plan is to get back together by this week and head to a race called 'Bodatious' in Virginia this weekend. Barring no bent valves, we should be able to make it no problem.

I purchased a BWS482. The only exhaust housing that was available was the 1.25AR. I'm hoping the spooling nitrous will step in and get it on its ear in ample time. I'm also thinking this will help to reduce the overspeeding issue.

Again, we are learning. I need to install another boost gauge to monitor drive pressure in the manifold. We have purchased a go pro camera and I'll set it up to monitor the gauges while making a pass. I went ahead and purchased a nozzle holder and fitting to take the -4 line to a -3. I ordered some .125" jets and will start out with one of those. If it looks like the drive pressure is good, I drill out the other jets until we get back to just before scattering the turbo.

My wheel man has to work this weekend so I'll be driving. It's crazy how much harder my heart thumps when Craig is driving.
 
Don't do it without a gate, you'll break the turbo again!

Possibly. lol In your opinion JQ, what kind of a shot in HP do you think we hit the thing with that killed the turbo? Again, it was full 4an from bottle to intake with a 1/4" fitting in the intake and no controller.

My plan is to take the 1/4" fitting, which has a 3/16" ID and replace it with the 1/8" nitrous nozzle. This is the same size nozzle we spool the turbo with. Granted the spooling solenoid is a small and the big nitrous has the largest solenoid available.

Our mud runs last less than 3 seconds. I can run the progressive controller, but, how much is it actually going to help in 3 seconds?
 
For now I would just run whatever amount of nitrous it takes to get the turbo lit until you have an external gate. On my truck with both the internal and external gates shut it will make 60psi on fuel. With both gates wide open, it will still make 60psi on nitrous, but barely 35psi on fuel. With large turbos like yours you can also over accelerate them, like going from 20psi to 65psi too fast. If you're already leaving the line at 30-40psi might be ok in your case. A larger housing will help, but with the external gate that's like having a hole that's nearly 2 inches in diameter in the manifold and still barely being able to bleed off the pressure. The shot depends on what kind of solenoid you have. I run two .125's. What size did you have in your 4an bottle to intake setup? I'm assuming you weren't just turning on the bottle by hand while staging, but ya never know with you LOL
 
This is an amazing build!

Thanks!! It's been quite the adventure.

Ha ha, we did it again and didn't break the turbo. Nananana LOL

I just have to share last weeks struggles. Since I'm waiting on Craig to come out of recovery with, yet again, another broke leg I may as well use the time wisely. It wasn't another femur, thank you Lord. This time he simply took a bad step at work and rolled his ankle. He ended up breaking his fibula and dislocating his ankle joint. He'll be down for a couple months so he'll be able to come with us when we race. lol Honestly, his momma is at ease since Craig will be recovering on our couch. I get my boy back for a few months.:rockwoot:

Anyway, I was set on hitting the Bodatious race in Virginia last weekend. I had the pan, the timing cover, and the head off and all the gaskets to go back together. I had popped the pistons out of the bores just enough to let the top ring come out and I filed the nasty off the top. When I shoved the pistons back down in, the #6 piston sorta slid in on it's own after leaving the ring compressor. So, I pulled this piston all the way out and found out where the metal in the oil pan came from. The ring land between the oil ring and the first compression ring had broken and chewed itself up pretty good.

This is about 3:45PM Thursday evening and I'm scrambling trying to find a piston. After making all my frantic phone calls, I pulled other pistons jus to make sure and all the others seemed good at a quick glance. The Mountaineer Diesel boys were coming up empty handed and suggested calling Enterprise Engine. I wore their phone out and Tara finally answered just before 5:00PM. She had the piston and I talked her into having a fella stay late and fly cut it for me and the wife and I jumped in the car and headed for Ridenour Road, OH. We arrived back home at midnight and I hit the sack. I took Friday off to get ready and woke up early knowing I had a lot to get done.

The first on the list was to clean up the other pistons and get them re-installed. Upon clean-up, I found the #4 piston ring land was cracked and getting ready to break off. I called a very good friend and coaxed him into making the drive to Enterprise for me. I again wore out Enterprise Engines phone until Jeff answered. He said the machine shop was closed on Friday and he didn't think he'd be able to get it done. Just then, the owner, whom I don't know, walked into Enterprise and made the commitment to cut the piston.

I called Tim Champ, the very good friend mentioned earlier, and headed him toward the Buckeye State. He returned at 3:00PM and I commenced assembling the rest of the engine. We fired 'er off at midnight and warmed her up for a re-torque. The wife, Christian, Steve Butcher, and myself, prepped and loaded everything for the race and I ended up settling in at 3:00AM.

We left out at 5:30AM with tired eyes and the excitement of racing keeping me awake. We ended up driving a little more than the required 5 hrs and when mapquest told us we had arrived at our destination, we were dang near in NC. Yep, we were in Danville, VA. This is three ours from our actual destination. Steve Butcher calls and asked where we are at 'cause they are holding up the race until we arrive. I told him to go ahead and race and we'd see them some time that evening.

Needless to say, we arrived at Bodatious sometime around 3:00PM Saturday after all the racing was over. I ended up hitting the sack around 6:00PM and slept the better part of 12hrs. I woke up Sunday morning a brand new man. I don't know if it was divine intervention or just plain bad luck, but, I'd rather forget that Saturday ever happened.

Anyway, we ran 6 passes on Sunday. The track was 200' long and it had some pretty decent bite. Our quickest run was the first run at a 3.34. We were fighting big tranny temps after the first run. After the first three runs, we turned on the big nitrous kit with the newly installed .125 jet. The thing felt great and didn't blow up, but, we lost et on every pass. I'm guessing the converter is going south so I've already pulled it out and sent it to Allen Pope.

I'll try to get some videos up later this week. I met a fellow Compd person at the event and didn't realize it until he PM'd me a couple days ago. Nice to meet ya Kleann.

We are hoping to hit the club race in Parson's, WV on the 27th.

That is a tough injury. I did the same thing last December. 2 surgeries later, I am still going to therapy. Hopefully your son heals quickly.
 
You might not have heard me say I was on here, when I said it. Nice to meet you also! The truck definitely had me and everyone else very impressed! It is super quick, even with it not running to full potential. All it needs now is an Al block in it....haha
 
Oh yeah an Aluminum Blco would be aewsome !!!

Hey, Do they make those with coolant passages ? street truck usage ? Drifting truck is what I been thinking about building .. will see

Yep. The extra work costs around $1200 more.

One major thing is holding me back. The outlaw pro-stock class I've been running in the MRA requires you have an iron block. Granted, the iron block gassers I'm running against are approaching the 800 cu in plateau. Most of the fellas running at the top of the class are trying to get the rule changed to allow for the aluminum block.

I need to do some soul searching and find out where I want to be at the start of next season. I can't help but get competitive when I know with enough money and the right combo, I can run with these boys and do it with a street legal truck.

I've been researching the storm and 55 blocks as I was told they are the strongest. For sure, the rods and pistons will be up to par for next season.

It is super quick, even with it not running to full potential.

Thanks Kleann. It could be so much quicker. I hate to run against those boys and get 6 tenths put on me. Could you just imagine an engine, like the Schied dragster is running, installed in the little ram 50. Other than the aluminum block, everything else would be legal for the outlaw pro stock class.

We'll just have to wait and see.
 
do a 3/4 or full fill, and water cool the head... it will stabilize the block tremendously.
and you can then get away with a smaller radiator, and upsize the oil cooler (like a small rad, instead of water.) and lose a few gallons of water off the front too.

I don't think I'd be able to street drive the truck if the block was filled. The aluminum block in the schied dragster is a water block so I know they'll take the abuse and live on the street.

Why so much trouble? Craig seems to be healing well. Lots of tissue damage this time. His ankle looks the same color as some of the oil we've drained out of Bodacious. lol

We made it over to Parsons this weekend for the Tucker County 4-wheeler club race. I don't think I mentioned before, but, since we installed the larger s482 with 1.25AR, we have been getting some turbo flutter/surge. This weekend, the turbo flutter/surge was horrible. So much, in fact, we declined to run the bracket race. I think if I get a 1.10 exhaust housing, this will cure the surge?? Am I right?? or do I need to get a little larger turbine wheel?

Here are a couple vid's. We had the big nitrous on in both vids to give the folks a little fire show. The first pass the thing was awesome and only surged just a little bit off the line. The second pass, the turbo didn't stop surging until about 3/4 track. You can see the fire come on right about that time.

Unless I hear different from folks on here, I'm gonna get he 1.10ar exhaust housing and give it another try.
 
Hey Sting. I just went down and measured it. With my digital calipers, the largest diameter I could get on the turbine side was 87.22mm. I'm not sure how to measure the compressor side, but, across the very beginning of the fins, it measures 80.75mm. It currently has the 1.25ar exhaust housing.

The first surgery involved putting 2 screws in to stabilize the ankle. But when I broke the fibula, it somehow healed about 5mm shorter than it was originally. By doing that, it threw off the geometry in the ankle causing it to flop around like a fish. The second one involved cutting the fibula and extending it to its original length and removing a piece of bone from my hip as a filler piece. Then a plate with several screws to hold it all together. It's been 9 months now and the liagament that goes across the ankle still hurts daily, but it is improving. Tissue damage really takes a lot of time to heal.
 
Hey everybody. Little update. Dad ordered a .100AR housing. I bolted it up for him last night and we took it for a little spin. Wasn't quite cranking the RPM's that he would've liked but it didn't flutter or whatever you want to call it. Well this morning he and mom drove it up the highway a little ways to the lake to have some breakfast and he said it was fluttering like non-other. Then on their way home he said it fluttered under hardly any boost at all. He said that the up and down play in the shaft is enough that the wheel touches the comp housing.

I had an II 64/14 on an old first gen and brand new you could hear the comp wheel clicking on the compressor housing when you shut it down. It had a substantial amount of play up and down brand new but never failed. I know that is not near the caliber turbo as what we're dealing with here and maybe the weight from 80+mm of wheel makes all that difference. Dad thinks he got a dud because it's only lasted technically one pass before it started fussing with us.
 
you guys will get it figured out..
the flutering I think you are talking about is possibly surge.. big compressor and tight housing on the ex side tend to do that..
