JB4 Dyno Results 5/30/19

[ecko04]

I hit the dyno today and here's how we performed:
2019 GT1 RWD
The car went into the facility around 10:30am, and naturally, as the day progressed the temperatures increased.
Ambient Temp: 86 degrees Fahrenheit, roughly 100 in the dyno facility.
Elevation: 305ft
Fuel: 93 octane (Exxon) for maps 0, 1, and 2; ~E30 Map 3 (I did not test the mixture. I added 5 gallons of E85 to about 10.5 gallons of Exxon 93)
AFR: Will seem a little leaner due to using the Dyno's tailpipe sniffer and my exhaust being stock.
Previous "Mods": ADD W1 Dual Inlet Catch Can
Dyno: Dyno Dynamics (No correction factor was applied)

If you want to correct for your local Dynojet, add about 10-12% to these numbers.

Baseline
343hp
395ft/lb

Baseline AFR

Stillen Intake was installed
356hp
394ft/lb

Stillen Intake AFR

Next up, I had the HKS M45iL spark plugs installed. JB4 was also installed, OBDII and fuel wires connected

Stillen + HKS Plugs (Map0 - deactivated stock map)
358hp
386.2lb/ft

Stillen + HKS Plugs AFR

OK, now to the fun stuff

Stillen + HKS Plugs + JB4 Map1
382hp
452ft/lb

Stillen + HKS Plugs + JB4 Map1 AFR

Stillen + HKS Plugs + JB4 Map2
379hp
465ft/lb

Stillen + HKS Plugs + JB4 Map2 AFR

Stillen + HKS Plugs + JB4 Map3 (~E30)
383hp
482 ft/lb

Stillen + HKS Plugs + JB4 Map3 (~E30) AFR

Numbers aren't bad for a load dyno, have JB4 runs from the logs so we can check out timing advance and boost?

Map 2 made less power than map 1?

I'm surprised by then improvement from Stillen.

Thanks for the numbers!

3hp is negligible. The increase in torque is the biggie.

Unfortunately I didn’t capture that info. I didn’t realize how easy it was to log until I was on my way home.

 

[Terry@BMS]

Ah bummer... Would have been interesting to see and added some context to the runs. Next time!

Finally a dyno that was run by someone who knows what they are doing ! they even put a sniffer for the afr's on the exhaust.....that's the right way to dyno a car ! Congrats !
the only screw up was too much E85 in the tank.... im thinkin heatsoak/iats were to blame for not much increases on higher maps.....these runs were pretty much back to back....doesn't matter how many fans that were blowing into the front of the car....heatsoak crushed the later runs on the higher maps Wash

I wonder if more runs would have yielded better results on Map 2/3. Ceteris paribus, +1LB boost max and +1.5-2LBS over the high end should have yielded HP gains. Although I'm sure USA 93 octane is "good" gas, I wonder if timing was not yet optimized to reflect maximum potential gains after the learning curve.

Shouldn’t have been too much E85. I followed Terry’s recommendation. Adding 5 gallons of corn juice to the 11 gallons of 93 I already had should’ve yielded around E33-E34.

The mistake I made, besides from not having logging figured out ahead of time, is that I didn’t have a test kit. I grabbed the jerrycan and E85 on my way to the facility. It was my first time using E85 and probably something I won’t use often.

I totally agree, heatsoak and IATs even given the cool time between maps 2 and 3 isn’t enough in an enclosed facility and temps hovering around 100.

It’s all good though, I’ve been to this same shop, same dyno technician, with 3 cars since 2008 and they’ve always treated me well. I know if I want dyno queen numbers to find a dynojet but that really wasn’t the purpose of my visit.

Typically, I throw a bunch of parts at the car then go to the dyno and base my gains on what others got when they hit the dyno in stock form. I wanted to do it right this time and I was more than pleasantly surprised. Aside from a larger intercooler I doubt I’d do anything else to it.

Next time I hit the dyno I’ll have the intercooler, logging, and E85 test kit figured out.

Seems pretty perfect right out the box. Congrats to KIA and fantastic work with the JB4 - Terry!

map 1 to map 2 were done too closely together, but 2 to 3 were almost 50 minutes apart, that should have been enough cool down time.

Why no map 5 if you had e85 mix?

You’re welcome to spend your money, strap your car to the dyno, and post results.

In all seriousness, Terry has stated multiple times that Map3 is the best map for mixtures up to E30. Sure I could’ve tried it, but why?

8/2018 - “It was interesting to note that map3 performed really well. I think I'd suggest most using E30 to run map3, while most running pump fuels to use map2. And we'll reserve map1 for the really bad fuel, stock spark plug, no fuel wires installed crowd.”

The man who did the development already provided the best guidance, coupled with dyno time, who am I, as an end user, to say otherwise and I’m definitely not using my car as the guinea pig.

Not to mention aside from the intake and catch can I am 100% stock. From Terry’s own testing and graphs, he picked up 7whp on Map5 over Map3 and 1 less wtq, so it’s not worth it if he already said which map is best for the fuel mix.

Couple the aforementioned with 100 degrees and heat soak, there are reasonable limits to pushing the boundaries and I’d like to not explore them.

Excellent information and comparison

Seem pretty offended at a simple question. Was just wondering why you didn't explore the map5 option. You have the fuel wires, mods, etc, enough for it. You quoted something close to a year old, which doesn't have as much validity anymore since there have been so many updates on the JB4.

Late to the party asking me to strap mine down, been there, done that. Which is why I was curious to your results seeing as you're RWD as well.

Not offended. I’ve not seen Terry post anything to the contrary in regards to Map3 being recommended for most running E30 as opposed to Map5 therefore the 9 months since posting that gives further credence to remaining on Map3.

Updates or not, until the recommendation is updated I have no reason to run it. And given the fact that he made 7whp more on Map5, I didn’t see a need to run it on an otherwise stock car.

Maybe next time if I upgrade the intercooler to drop those IATs.

Pretty light gains compared to what BMS posts on their site for stock (327whp) and map 2 with intake (416whp).

I believe that 416WHP run was with fuel wires, which gain you about 20-30hp peak from what I remember seeing, compared to not having them installed. That makes this dyno with hot intake temps pretty close all things considered?

**edit, it was actually only about 10-15hp run over run with just the fuel wires hooked up**

The OP has fuel fires too.

I sure hope not.

Check out the post again. He hooked them up.
