People keep telling me I need to run E85, or M5, or E100. That's fine if you have the time to maintain you fuel system, but I don't. I'd rather leave fuel in the system when I'm away for work, and not worry about it.
I'd also like to be able to refuel the car at places other than my house....
Ah, I understand now. Yes, I now agree a swap is in order to reach those goals without extensive work to the inline 6. You could do a big single or twin 60mm. Whichever route you go, reaching 160 in 5 seconds (1/8th mile) will need plenty of power and even better traction.
1997 328is - Megasquirt PNP, Holset HX35, Deka 80lb injectors, SPA T3, Precision PW39 WG, Synapse Synchronic BOV, DKM Organic Twin Disc Clutch, Innovate LC-2 W/B, Mishimoto Intercooler, Mishimoto Catch Can, Mishimoto Rad, Devils Own Meth, Porsche 911 calipers with E46 M3 rotors, Corsa Exhaust
For a 600 hp car it would be awsome to be able to just pull into any pump and fill it up with 91 and bottle of windshield washer fluid for the meth tank, but if you really want to push it alcohol is the way to go. We finally got an E85 station back in town now. I used to have to drive 60 miles round trip to go fill it up. The same station has 100 octane unleaded on pump for $9/gallon
Closest E85 for me is more than 1,000km away.
I pay $8/litre for 114 Octane. Mixed down to 100 octane (with 91 octane) it works out to $4/Litre, or $15.14 CDN / Gallon. (If you convert that at today's rate, it's about $11.62 USD)
I'm seriously considering running a second fuel cell in the car, with a second bank of fuel injectors just for race fuel.
That sounds super expensive. What about methanol or ethanol in a second fuel cell? Seems the alcohol based fuels are a bit cheaper than high octane race fuel when I looked at it. Or doing a really high content methanol/water injection setup, although staged injection is better and generally more reliable IMO.
I vote for the atlas engine just because I have one and always found it to feel weaker than it's ratings and would love to see their full potential. I haven't seen anything in the way of bolt-ons from them.
I've considered it, but still would be highly destructive to my existing fuel system components. The cost to convert to alcohol capability, would probably be more than any savings I'd gain over using the stuff I have with race fuel. My local race shop has also had all kinds of problems with running alcohol in 2 of his race cars, where he's constantly having to flush his fuel system due to breather contamination. (We often get temperature swings cycling below dew point with lots of humidity in the air, that gets sucked into the fuel cell) I think at one point, he said he was throwing away just as much fuel as he was burning. Over the past 5 years he's switched from C16, to Q16, to Methanol, to E85, and now he's on straight 114 octane race fuel....and couldn't be happier. Q16 he said was great when it ran, but it had all kinds of stuff in it that you would have to "pickle" your fuel system in some other fuel between events.
Interesting. It was pretty easy in Houston, TX to do E85. Never heard of anybody having fuel system issues with it, but it very very rarely went below freezing, and dew point was like 76-80 F most the year, so humidity was constant, but everything stayed warm.
50/50 water/meth injection have that problem too?

I think this is the same car. I’ll have to do some more digging later and see if I can find more info or a contact email.

I have m50 2.8 forged rods and pistons 11mm arp s54 studs Athena cut ring gasket car was tuned on e50 mad 413kw 720nm on 1.2bar boost the problem is I get oil in my expansion bottle on the top no ova heating no pressure build up ! Any help wid be appreciated thanks
Uneven block/head surfaces ? A faulty HG ? Athena is made in Italy, so ..
At those power levels, you could get away with a stock HG and regular M50 10mm ARP2000 studs. Have done it many times.
