SynDiesel Fuel Test:

[McRat]

Today Jason and I (and some help from Robert Miller for truck prep) went to Westech's SuperFlow dyno to do the first stage of fuel testing.

We used a 2004.5 LLY with 89,000 mi. Modifications were aftermarket exhaust, Air Raid cold air induction, and EGR delete. Tuning was the stock tune file for all tests. Baseline was ULSD pump diesel. All tests were 3 pulls or more. Only pulls that overlayed each other better than 2hp (1%) error were used.

Pump ULSD = 233rwhp average

SynDiesel racing diesel from Hyperfuels = 231rwhp average

We went back to the ULSD at the end, and it overlayed within 2 HP.

Basically, with a "stock" truck and tuning, it doesn't matter which of these you use. Claims of 5-8% performance increases with a stock truck are not realistic IMO.

Next will be testing on a full race setup.

Interesting find.

I went through 55 gallons of it & found less then 1mpg better with syn, didn't see any major improvements while pulling(SOTP). I did notice less smoke though. This was with my best tune. FWIW

I was looking at it a year and a 1/2 ago also, it is sapose to have a lot more BTU's in it from what I read. Exxon said it wasn't forsale even last summer. Who is the supplier and at what cost?

I was also told if it would have came out soon, the DPF stuff would not have to be on the truck because it burns that much cleaner.

I was told you could run more timing without engine knock and that it had an extremely high cetain level.
:dontknow:

Thanks McRat :cool2:

 

[McRat]

Well, it smells odd (kind of like wax), and the exhaust is cleaner. We ran a tank of it through Wendy first to see what driveability was like, and I really didn't notice any change but less smoke and smell.

But the dyno is the real proof of the answers I'm looking for.

 

[SIKDMAX]

Interesting stuff Pat. Thanks for doing that.

Anything else happen on the dyno?

When i wanted to try SynDiesel i found a VW forum and they posted results from MPG increases and horsepower increases when tested at the drag strip? They claimed a 5-10% increase one guy even had a Duramax.... they all agreed the cars drove better, quieter, and was SOTP quicker. I trust your results though Pat

How much is syndiesel? jw I don't think anyone in Kentucky even has it

 

[MadMaxx61]

humm wonder if this will help me pass an E-Test as I dont have the DPF anymore on the truck and dont want to put it back on.

425$ for a 55 gallon drum plus freight which is stupid expensive

Let me get out the calculater :rofl:

 

[McRat]

I'd certainly like others to test it, nothing beats more data. I'll admit I was a little pissed, as I was shopping for 5% "free" HP. That's 25rwhp on a 500HP tune.

As far as any additional tests I did, well... that's another topic for a new day. Still looking around.

I bought a barrel from Hyperfuels in Texas.

It almost seems strange though which is where the frustration comes from im sure Higher BTU's, higher Cetane... yet no hp increase? seems odd to me. I wonder if SynDiesel is mistaken on their increased numbers?

claim from a TDI guy

I've used it at the track, blended 50/50 with regular diesel. Getting the cetane over 49 or 50 doesn't help much as the engine is designed to run on that cetane level. At a short track (Gingerman) it was good for about 2 sec. a lap. The big problem is the expense, especially shipping. Hiperfuels is in Houston, so if you're near there and can pick it up it becomes more economical.

Given its cost I'd be inclined to run 50% bio (54 cetane) to bring the numbers up in dino diesel.

 

[McRat]

2 seconds a lap is more than the difference between a stock Camaro and Corvette. You could put a supercharger on your car and not pick up 2 seconds a lap.

I'm having a hard time believing his claim...

 

[TheBac]

Thanks for doing that test, Pat. How much fuel did you did have in the tank per run? Did you drain the fuel system to make sure the fuel was 100% syn or reg and how did you go about draining it? Were the runs essentially back-to-back?

IMO, this syndiesel sounds like more "gourmet" rubbish, companies trying to take advantage of the public's lack of knowledge.

Agreed, if he is picking up 2 seconds, he must be running a long long long track, like 50 miles or so lol

We ran a "standalone" fuel system. Two fuel jugs, one in, one out. We started the tests when at least 1 gallon of fuel had returned to purge the system, and did multiple pulls. We did not re-used fuel for testing, we dumped it in our regular fuel tanks.

We started with DinoDiesel, then tested Syndiesel, then went back to the DinoDiesel to confirm.

Now, could you edit the tuning and make more power with Syndiesel than DinoDiesel? That will be the next testing. For now, I have no data that would say that Syndiesel will do much of anything in a stock common rail truck.

And at $425 for a 55gal drum, you would be better of with a water/meth mix for sure for that kinda gain/per cost gal.
