B16: All Stock - E85 Dyno Tune
This car belongs to Zac. He's one of our mechanics. His Del Sol has a stock B16 swap, down to the stock air box and stock header. He's currently made the switch over to E85, and is obviously having great luck with it.
Here is the setup:
Stock B16
DSM 450cc injectors
3" exhaust
Tuned on Crome Gold
Most stock B16 swaps make around 135-145 whp on our dyno. By making the switch to E85, we were able to run a good bit more ignition timing, and the results are good. We were able to make up for most of the power lost through the drive train. On this pull, we stopped at 7600 RPM, because power was dropping off, and there was no reason to keep going.

And the video:

Zac will be adding an SMSP header to the mix soon, and maybe some cams. Update to come.

We just got some ITB's for it....
I think we may end up doing a mod by mod type of thing where we document how much power each mod increased and then do the ITB's last.

155 = J spec B16 with 2.5" header back exhaust/ 3" short ram intake
140 = USDM B16a3 with DC 4-2-1 header/2.25 tanabe exhaust w/stock cat /AEM short ram (bought like this)
I think if this is a USDM B16 your results are AWESOME...I think with a decent header and intake its gonna be impressive.
How much more timing did you add with the E85 vs 91?

I just got home from the shop and don't have the tune to look at but I'm guessing anywhere from 5-7 degrees over what was an already a tuned pump gas base map which probably had another 3-4 degrees in it and yep, it's an OBD1 ECU. All questions are welcomed.
What's needed is basically 35-41% more fuel over pump 93 octane. You can usually do this through a fuel pressure regulator instead of buying new injectors and yes, you can count on needing a bigger fuel pump.
If you know that a bosch 044 supports 600 WHP on pump gas then take 35-40% off that number and that's what it can support on E85. It's not exact but it's accurate. That's how you figure out if you need an extra fuel pump or not.

WHERE ARE SOME STATIONS? ANY HELP WITH ADDRESSES OR SOMETHING? ALSO IM GOING TURBO WOULD THAT BE A WISE CHOICE OF FUEL? I HAVE RC650CC INJECTORS ON THE SIDE ILL PUT WHEN I DROP THE TURBO, ALREADY IN THE CAR ARE WALBRO 255 FUEL PUMP, BENEN FUEL RAIL,AEM HIGH FLOW FUEL FILTER,BLOX FPR, 3" STRAIGHT PIPE AND BUBBA TUNED DO IT DYNO WOULD I RUN INTO ANY PROBLEMS WITH E85?
^^ E85 is even better for forced induction setups.
We are actually tuning a high compression turbocharged setup today on E85. I'll post that results up tonight on the FI subforum.

so how much hp and torque were actualy picked up from the switch from 93, to E85, also what was the tune on 93 octane i have a jdm b16 2nd gen and run 93 on my odb1 ecu, i want to tune it because i belive with the header and intake and high flow cat and exhuast i could pick up more power, on 93 with a tune, and even more with E85 if all i would need is a FPR and a Walbro 225 pump, and run the same fuel injectors as you for 200 or less. If you have a dyno of the 93 tune and what type of timming you ran that would be great thanks jay.
Good to see someone still playing with a B16a,E85 loves big injectors and 60+psi of fuel pressure.It will be interesting to see what this setup does with h/e/I.
^^ Probably around 10-14 whp and 10-11 torque when compared against same setup's from the past on 93 oct.. We didn't tune it on 93 octane so I don't have that chart. It's not so simple as "how much timing did you use". Ignition values change based on load and rpm so it's not as simple as saying 16 or 18 degrees and so on.
yeah i dont know much about tunning besides basic's, id have the car tuned by a good local tuner, but for that much of a pickup is crazy FOR e85 , does hondata s100 have the cabality to tune e85 ?
Depends on your current injector duty cycles and base fuel pressure.
Most all motor cars is as simple as a walboro 255 and an adjustable fuel pressure regulator on stock injectors
or
walboro 255 and larger injectors.

power gain is partially from pushing more fuel into the engine and effectively raising the dynamic compression ratio, any engine should see an increase when changing to e85. very nice gains though for a small, stock motor.
