Dyno results and discussion

Okay Chris, (and everyone else, and us ), Jeff and I discussed it more, he is in the process now of building the turbo-swap down-pipe. We just needed to be told to quit being so lazy and get to work.....LOL. Not sure how much time we will have to swap turbo's there, but we will go prepared with H1C - 18cm^2 on the truck and the HX35 - 16cm^2 waste-gated housing in a box. Should have the HX35 on the truck for testing and setting the boost levels Friday. Still have not received the new video camera battery (old one is only good for like 1min.)

So how it looks now, we plan to dyno two turbo's to compare, one gated and one not. We will also as time permits dyno with straight water then water/meth mixture (not totally decided on % of methyl alcohol yet), to be able to have some good comparison #'s.

With us it goes without saying; when money leaves the peanut butter jar, we want to have as much as possible in return for it.....:hihi::D (some call that thrifty, some call that down-right cheap.....:thumbsup:). We call that the "Sanford and son" method...LOFAOADL.

To me that is being thrifty, getting your moneys worth, making lincoln squeal. That last one is more for the southern neighbors since we have Lincolns head on our penny.

I wish I knew enough to be able to contribute to these turbo threads, but I just lurk and enjoy since I'm uneducated about turbos.

I am sure that you both will be as ready as you can be, just remember that a vid is part of the agreement from the start....LOL

Best of luck to Y'all from down south......
 
Forgot to mention, My Kennedy pistons came in yesterday, waiting on a new clutch & flywheel from South Bend now, then off to the balancing shop then maybe I can start the coating process and then get something put together ...... still going to be the fall for me ....
 
here ya go guys, this is our vid, but there was no sound because the camera we borrowed was full of precious child-hood videos, so it was shot with our digital camera, but it has no sound...:(... but i edited it all together and put some music too it, so enjoy......:hihi:

here are the results.... first off let us state that we were not prepared with the necessary things to go on the dyno ( need to have a second pick-up for the tach signal, and since we do not have a tach, the results are not entirely accurate) and the mustang dyno is made to plug to OBDII..... we did the best we could, and set the bar low so there is only room for improvement....:agreed:.... on a side note, Tim and Chris at TNE Diesel were extremely accommodating for us, and we thank them very much... and next time out in may we will be better prepared....:D

I can't open it. Can you just give us the numbers?

I just had a whole page of our days actions, late, police, fines, not prepared...LOL.

We did 7 runs, never had a chance to swap turbos, as the first few runs were to try to dial-in as they needed a pulse signal and we run off alternator. We also realized our torque convertor was locking hit and miss (need a lock-up mod...LOL).

The dyno sheets are not in order, 2 and 3 are mixed. First run with water was 182rwhp@345ftlbs rwtq. Second run with 25% meth, 195rwhp@321ftlbs rwtq. The third sheet (seventh run) no water/meth (part of the long story...LOL) 200rwhp@353 ftlbs rwtq. For the last run I disconnected the boost relay for the water/meth (supposed to unplugg the boost gauge....LOL) and we showed the boost we were hitting, 24.5psi. In the seven runs, we varied 32 hp and about 60 ftlbs torque. It gives us a baseline, and need to tighten up our act for May 12 (we are going again, do not even need mods to better these numbers....LOL).
 
Not too shabby, peak torque rpm is a lot higher than the 1800 rpm I recall hearing.
 
heres some home-made photos of the sheets... really have too
work hard here to get paid..LOL:hihi:

the third sheet shows the boost... 24.5 psi...

speaking of getting paid.....how much?
Click to expand...

well...... the dyno costs 150.00\hr., the reckless driving ticket was 325.00, 5 hrs. there and back, still grinning from ear to ear... priceless.... how does 75.00 bucks sound? actually it is only 55.00 because we will recontribute our 20.00 again....:hihi:.... so, who is going to be next on the truck-treadmill/humbler...

just as a side note, you guys cant imagine the anxiety of sitting behind the wheel and pushing the fuel pedal through the floorboards 7 times in a row... next time i wanna take earmuffs....:agreed:..... i did not even realize that the pedal pushed that far down, and we have owned this truck for 5 years...:eek:

KBC

He was very nervous at first, but realizes now (I hope anyways) that this is the best way to test a powertrain.....no traffic, no bumpy roads, no police...LOL.....doing 0-70mph runs on a treadmill. We plan to go back in May, hopefully with the Caprice on the trailer (no fast driving pulling the trailer...LOL).

Some things are better learned the hard way, myself, I learn from others mistakes, look at it this way, you didn't blow your motor up LOL.

I half to admit I was expecting bigger numbers, maybe next time things will go better....
 
I expected better numbers as well. I have been looking for a dyno sheet I have of my 98 from years ago, heath ecm and propane. It was a mustang dyno at a big Dodge event. just under 200rwhp with the ecm and 225 with the propane. Tq was all over the place as the tach pickup was not reliable enough.
The power curve was not as flat as the one posted, power dropped off fast near 3000rpm's
 
Turbo Shootout.

Up next is a turbo shootout.
ATT vs. Holset with a possible GM3 GM4 'baseline' done later.

What rig would you like to see?

1993 DB2 6.2 with 6.5 NA heads. Gapless rings. Boost and EGT. TCC override switch. Auto. 4.10. Could be a good show if the main cracks let go. :rolleyes5:
Close to the other dyno'd ATT truck in configuration. (Including NA application 6.5 precups.)

1995 DS4 6.2 with NA military 6.2 heads and precups. EGT. Boost from ECM sensor. Auto. 3.73.
Useful for 6.2 owners not wanting to change precups.

The extended test could be done to show MPG on a Payson towing run.
