F80 M3 with 580 HP

M3 tuned to 580 HP??? I wonder if it is on stock turbos or not. over 600 ft-lbs of torque.

[Spinny02]

No mention how they tested? I am sure the car is a beast if numbers are true.

[RPiM5]

They would have had to crack the ecu for those kind of numbers or NOS. No mention of who the tuners are. I personally don't believe it until I see it.

Thats tightie's car from speed district. He just posted all the pics up on the f80M forum. He has been known to have some pretty fast cars!

[RPiM5]

I talked with the owner of the F80. He's just running the JB4 that came out from BMS a while back. He said he got 491whp I assume not on a Maha dyno though.

You're making 1000 hp now?

4 of us just made over ~520whp/550wtq which is actually right around the numbers in that article. The EAS car was even better. Check the F8x photos/videos thread today for Tom's update.

Dynos are all different Dave, you know this... with the right operator and machine anything is possible

I know that some of the F8X cars at EAS last Saturday (close to my house) were all up in the low 500's to mid 500's on JB4's with exhaust, downpipes, and of course, much better fuel. This was the same dyno where my stock M5 pulled 535 whp so with JB4 tweaking the boost to very high numbers this is possible. But I hear the resistor tune is the way its going to be for some time.

Isnt funny how the F80 comes out and mods are almost immediately available sans a true ecu tune. Im over at the M3/M4 side to see their brilliant cars and there are so many already with M performance aesthetics and mods. I remember when I got my M5 in 2012 (Oct) I think I had IND for reflectors and grilles and H&R for springs but that was really it.

Is that crank HP? If so that's not anything unreasonable.

[Timberwolf]

I know of a local F80 that's running a beta JB4 with tons of boost and downpipes making 580WHP and 605WTQ on MS109 last I checked. Who knows how long that will last but I can bet it will take a serious F10 to keep up!! This car was tested on the same Dynojet I use where I made my 692/647 on MS109.

No joke man. The M3/M4 is just such a bigger market. The thing with me is that after being in this game for such a long time and reading and reading and reading and watching and looking at information about all of the dyno machines out there over the years, I have come to a personal conclusion that the only dyno I trust to put out actual engine power and torque numbers are the Maha systems. I understand what ColdList always talks about when talking about dyno's and I pretty much agree with him. I don't know what true drive train loss ratios are for M5's or M4's and the truth is that nobody does especially because it's all different for different dyno systems. I've put my cars on the dyno at EAS before too and it is a great way to compare against other cars on the same exact dyno for consistency reasons.

Do I believe that the F80 M3 in question was really put on EAS's dyno or any other Southern California dyno? Certainly. Do I believe that many people who are putting on the JB4 piggyback module are dyno'ing 491whp, 500whp. 520whp on Southern California dyno machines? Certainly. Do I believe any one of those cars is actually making 580hp to crank? Absolutely not. They are all probably making somewhere closer to 500 crank horsepower in real life, but that is just my opinion, and the truth is that we will never know because there are no MAHA dyno's I know of in SoCal.

I bet you a 100 bucks it's not faster than my M6 trap speed or 60-130 mph . If it is really making 550whp it would destroy my 132 mph Vbox. 1/4 mile speed and 7.3 sec 60-130 mph .

[shahano]

Maybe we can ask them over on that forum to try it out.

Those will add 10hp. Don't' you know this by now VIC?

It's not possible at all to have 500 HP F8X M3/M4. I'm just leery about the fuel pump handling that much power. Hope none will go into limp mode while racing.

I agree--- its only making peak 580 hp on a favorable dyno and no one has seen the curves to see what the car makes in the real world street rpm range.

Im going to drive an M3 today that was at that local dyno event and it made 524 whp with its JB4 resistor tune. Ill give my impressions and Im sure it will be fast since I know the dyno and my stock M5 (2013) made 535hp on the same dyno but with a different hp/tq thru the usable range.

The peak numbers are total BS IMHO based on the performance we've seen thus far , on top of that if you look at the curves the peak hp is at only 4500 rpm and drops off rapidly after that . Especially on a 60-130 run and the 1/4 mile trap the lack of top end power will hurt . But if it really made that peak power at what it weights it would still be significantly faster period , no excuses . You can make a dyno say anything you want , and honestly all dynos on this site are inflated M5/6 included .

Inflated or not this 580 wheel hp m3 gave a built stroker motor ess vt3 a serious run till the turbos lost steam in the tripple digits.

Not sure about the 60 to 130 but i got to finally drive a f80 and i was impressed. To say the least Very meaty power band, and way more aggressive dct engagement that the f10. Like all the dyno curves state the car loses power higher in the range. But its very snappy and nimble which is nice especially in the first three gears. A nice single turbo conversion with some beefed up connecting rods and you'd have a 750 wheel beast that weighs 3500lbs. Its still not enough for me to downsize from the M5.

It's interesting
Couple weeks ago 800 HP M5 and now 580 HP M3... what is next?

AI need to see trap speeds and 60-130 numbers . I'm so sick of dynos and relative speed comparisons from street racing. As you know reaction time what gear the cars started in etc can greatly effect the outcome . If you start a supercharged E92 , even a Stroker one , in the wrong gear it's nothing special . The built stroker supercharged E92 recently did 60-130 in 5.9 seconds . That's over 2 seconds faster than the fastest 60-130 for the "580whp" M4 . That's bus lengths difference , not even in the same league . Bottom line is we have seen zero proof of 580 whp at this point .

This was my point all along.

LOL...
I'm expecting 1000+ HP M6
