Who’s ready for dyno numbers and broke parts???

Figured I would start a new thread. Anyone wanting to know the combo can look at “not an a body but it it’s turboed” for specifics. Let’s get to it!!!

Helping my nephew over the weekend and he asked if we could deliver an engine he built over to Paul. Went to Paul’s who owns LS1 excitement, he does LS swaps has a mustang dyno.
Once there, Paul was checking the truck out and asked what kinda power you think it makes? Told him I had no idea, but it feels like 250/270ish and with that said we had it strapped down, I made a series of pulls and the numbers were 220hp and 300ftlbs. A little less than I was hoping for. This was on 4-5 pounds roughly and the AFR’s were 11.5-12.4. Paul said his dyno was roughly 12-15% lower numbers than a dynojet. So 240ish HP and 336 ftlbs for comparison.
RPM signal lead wasn’t working properly so we went off the roller rpm to match engine rpm. Crude but it worked somewhat. Not sure how accurate it is/was.
I looked my year 318 on Allpar and it showed my engine making 170hp and 280ftlbs at the flywheel. This was when new and my poor Truck has well over 200k on it.
Do the calculation for flywheel to wheel power and my 318 is making 84 hp and 76 more foot pounds than stock. Averages to 16 hp per pound. Not crazy but impressive with a stock 318. We are talking wheel horsepower. Don’t quote flywheel numbers when you bash, or make fun of mine..blah, blah, blah.....
Made 8-10 pulls and it felt like the truck was gonna shake apart from these mud tires I installed recently. Most rpm was 4650 and 115mph. And it was still pulling, dyno graph showed, but I was running out of fuel on this 38 degree night.
Last 2 pulls we noticed the truck was struggling to make 3-4 pounds of boost but was still averaging 214-216 hp. Packed up and headed home a little dissatisfied with my results.. My nephew is going to upload on YouTube for y’alls enjoyment. I will let ya know when he does.
We stopped and had dinner and gave this thing some more flogging and burnouts as if it didn’t have enough already. Well apparently it had!!!
Turbo locked up on the way home. Blew it apart and found this in the oil restrictor. Looks like when it was machined and not cleaned properly or it came from my brass fitting for the turbo feed line. That may have been what killed my other one...
New bearings are ordered and I will reassemble and keep beating on this thing!! Keep ya posted. We will be going back to Paul’s with more fuel and boost soon. Overall I’m pleased, It never smoked, knocked, rattled or otherwise and took me back home with little effort. May change cam and valvesprings over the next month or so. Has Been together 1 year as of today. Love this thing!!!!

Did you slap another China Turbo on it and keep burning the tires?

I love carnage.......especially when it's not mine. lol

Hey thanks for asking. I didn’t. I bought a rebuild kit and it was wrong ( imagine that )! I may go late model Hemi..And turbo. I’m just figuring what I want to do. Maybe after Christmas I will give an update.

Late model Hemi would be awesome! I'll definitely be tuning in for that, but it would be awesome to see the 318 pushed to it's limits!

Fun to see some results,even thought its never fun to see stuff being broken.
Regarding engineswaps its your car but i bet you can make a ton more power given some time and a fresh longblock would certainly make more power than what you are making now,and it is easy to do over time,an engienswap however tend ot burn time and money like you would not believe and that is just for the swap not for buildling more power..

Yes I’m with you. I’m sure this 318 is tired, with well over 200k on it. It’s bigger brother, 360 magnum sits on the stand waiting it’s turn. That would be the easiest as far as swaps go. The hemi would take some money and even more time to get sorted out. Let me get the fueling back right and double the boost and we will see how much more this 318 can make.

Update: Chineseium turbo ordered and hopefully here by the 29th. Same type but from a different company, I’m sure they are all made at the same place. I did a bunch of research and I am going to do away with the oil restrictior on the turbo feed line. Some of my buddy’s have them on there Turbo LS stuff and some don’t. According to everything I’ve read and heard, I don’t use one on a journal bearing turbo. Maybe subcom and others can give me there opinions and what they are using. To be continued with some mud tire burnout pics

I'm using the restrictor that came with my GT45 from DNA Motorsports. I couldn't tell you the size but it's small. Of course I probably don't drive mine as much as yours but it's been on the car about two years now.

That’s where I bought the replacement from

Back in action!! UPS came late last night and I got a head start early this morning. This turbo came with these white “assembly gloves” and some “special oil”! Drilled out the oil restrictior and had it all installed in under an hour. Maiden voyage complete. All is good.

Too kool,subscribed.
