Times for my 3500 Fiero

[caffeine]

Took my Fiero to the 1/4 mile this weekend (only one 1/4 mile event/year around here) and it really surprised me.

The first run was a 14.4, then a 14.1, then a 13.6 @ 102MPH!
I wasn't driving it as I was racing my Firebird but I am really excited about the times.

It's a 3500 with 65mm TB, stock 3500 injectors, stock motor, my own tune, and a 75hp shot of N2O. The 14.4 time was using nitrous in 3rd and 4th and the 14.1 and 13.6 were done with N2O in 2nd, 3rd, and 4th.

I'm also really excited to know that my stock Fiero 4 speed clutch (the one that was in the car when I bought it) still isn't slipping. I was half expecting to go home with a slipping clutch.

It seems sad that my LT1/T56 89 Firebird only got a 13.5 with 4.11 gears. Really makes me want to build a turbo 3500 for that car.

WTG! Were you running street tires?

[caffeine]

Yep 205/40R16 IIRC. One was a falken ziex don't know what the other was.

Get some DR's, tune and run E85 and you would be very low 13's!

[caffeine]

Too bad there's no E85 in Canada yet.

Nice times! where in Canada are you? their is 2 E85 gas stations that I know of in Ontario, one in Guelph, and I think the other one is in Kingston!

I'm in British Columbia (Vancouver Island)

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

Just get some DR's and tune it for 93..

I ran a 12.6 on a 100shot in a FWD automatic Beretta, granted I have a bit more done to the motor but I was doing 13.8's with a stock 3400 and the same shot, and that was with probably 750 bottle pressure... the new times are at 950psi

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.

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.

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.

Hence why I said since they started adding ethanol.

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.

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.

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.
