High HP on stock headgasket

[PEI330Ci]

Nope, I drive to the track. It has to survive drag week as well. We will see what direction I go. Another platform I'm interested in is the I6 atlas engine in the chevy trailblazers.

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....

My signsture is outdated, I’m waiting to finish the car to update it. The car has an S472sxe on it now and a TH400 trans. After changing a couple parts last minute the trans is rated for 1800 hp, so definitely not limited by drivetrain. Honestly I don’t think you guys understand where I want to go with this. You guys are still thinking like 160 mph in the 1/4, and I’m thinking like 150 mph in the 1/8th.

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.

This is why I went standalone, I'm flex fuel so when I store the car for the winter I'll just fill up with 93 and it'll be fine till spring.

Exactly. there is zero reason these days not to run alternative fuels. Pump gas blows.

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?

[M3 Muscle]

I think the block is filled (shows some block filler at the end)... and most def. runs methanol (as most fast race cars do) I'd say.

You should def. change to methanol IMO and let that new turbo sing

I'm guessing a billet block. It shows Inductech Billet Parts as a sponsor. They have a few inline 6 billet blocks on their Facebook page.

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.

Thought I would share this for group knowledge. On my last motor configuration I decided to try a stock gasket with no orings and S54 head studs just to see what would happen and what the limit on that would be. As you'll see below the limit was just about found. I pulled the head off today to make some motor changes and put in a cut ring gasket for safety reasons, and found the gasket was starting to push out on cylinder 2 and 5.

Just to recap the setup was a 2.8L built off a M50 block with stock bore wiseco pistons, 11.8:1 compression, stock headgasket, 11mm ARP head studs, and E85. The gasket is just a $30 victor reinz from amazon. I don't recall what the studs were torqued to but probably 100 or 110 ft lbs. It has a ton of passes on it at 28 lbs of boost and a dozen or so at 32 lbs. Probably about 800-850 whp.

Hard to see in the picture but normally the gasket is about a MM or so from the bore, but on cylinder 2 and 5 its about 3mm. Don't mind the clover leaf shape of the fire ring, they come that way stock to clear the valve reliefs in the chamber.

I don't know if it would have continued to push out and eventually fail, or mabey it would have stopped and stayed that way forever.

i wouldn’t say the limit was found if you had detonation...

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

[Laimis]

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.
