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!!!!
