Times for my 3500 Fiero

[Superdave]

Nice..

You certainly have an interesting track.

Wow I completely forgot to upload the video of this run haha.
My friend was driving the Fiero at this event cuz he blew up his RB20 and I was driving my Firebird. This was the first run he managed to break into the 13s with. Its funny how many people there expected the Fiero to be slow .

Here's another vid of the Fiero doing 1/16th mile. Almost looks like it does a mini-wheelie on the 1-2 shift haha. Gotta love blown stock shocks.

Yep and the only difference in the fuel system is the flex fuel version has a sensor to determine alcohol levels

Never mind I'm done.

The 3500 LZE is a flex fuel engine, not the LX9... Good god. Do some more research.

Ever said the Fiero was designed for it, the 3500 was. I was a little vague in my posting and I know very little about stuffing the 3500 into a Fiero but the stock the 3500 will handle E85 all day long, nothing in the physical fuel system needs to be changed. PCM wise all that needs to be done is to change the stoich afr from 14.7 to 9.76

If he's running the stock fuel system the only thing that would need to be changed on the Fiero would be any rubber fuel lines and adding the 30% more fuel.

Caffeine, you would need to know what injectors your currently running, lb/hr rating, and also the duty cycle that they are hitting at WOT since that would determine if you even have the headroom to add 30%. BUT you clearly stated that e85 is hard to get so it's just not worth the trouble. Go 112 of course after increasing the compression so you can use it LOL

I have a stock fuel pump and about 6" of rubber hose supply and return going to and from a vette fuel filter. Then braided line to the stock 3500 rail

Haha either way I can more easily get race fuel here than E85. I think the next step if I want to make more power is a cam.

Hence why I said since they started adding ethanol.

Not when the Fiero was built.

http://en.wikipedia.org/wiki/Ethanol_fuel

Ethanol fuel is ethanol (ethyl alcohol), the same type of alcohol found in alcoholic beverages. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline. World ethanol production for transport fuel tripled between 2000 and 2007 from 17 billion to more than 52 billion litres. From 2007 to 2008, the share of ethanol in global gasoline type fuel use increased from 3.7% to 5.4%.[1] In 2011 worldwide ethanol fuel production reached 22.36 billion U.S. liquid gallons (bg) (84.6 billion liters), with the United States as the top producer with 13.9 bg (52.6 billion liters), accounting for 62.2% of global production, followed by Brazil with 5.6 bg (21.1 billion liters).[2] Ethanol fuel has a "gasoline gallon equivalency" (GGE) value of 1.5 US gallons (5.7 L).[3]

10% wasn't readily available until the youngest Fiero was already 10yrs old.

I guess you don't get it... in 1980 there was no such thing as E10 fuel so nothing is able to withstand the ethanol... Also the flow of the pump will not be enough, the flow of the injectors will also probably not be enough unless he's currently running at 50% duty cycle... as well as none of the rubber lines are made to handle the 85% ethanol. So unless he's replaced all of that he would have quite a bit to do.

E85 is not a simple upgrade.

[bearbear3_4]

Sorry, 90% gasoline wasn't even thought of yet in the 80's bud. Only thing that "safe" on the swapped Fiero is the stock 3500 fuel rail if it was used. The stock pump is the same pump as the lsx and ltx generation motors, so the fuel system can handle some upgrades as you mention, but if he was to go e85, he will need 30% more volume due to the AFR's required.

[ForcedFirebird]

Stock pump and injectors can handle the extra fuel needed. Plus since they started adding ethanol to gas all fuel lines have been designed to withstand it.

yeah and upgrade the entire fuel system to support the now needed extra flow of the E85 to get the right mixture...

I'm not sure if DRs will make a huge difference as there was virtually zero wheelspin even with the open diff, but I really want to upgrade the transmission to an F23 possibly with a LSD.
