JB4 tuned BMW F80 M3 with downpipes on E85 vs. stock Hellcat and Ferrari 458 Italia

[Sticky]

A bolt on F80 M3 or F82 M4 is a potent thing. This F80 M3 has a BMS JB4 tune on Map 2 and is running an E85 blend. Additionally, the car has catless downpipes and an intake. The Hellcat is an 8-speed automatic that is completely stock.

The F80 M3 handles it well and pulls decisively. Impressive for sure.

Now, before the M3 got downpipes and other bolt ons it ran a Ferrari 458 Italia with just the JB4 and an intake on pump gas. It does not take much to make an F80 M3 stout:

BAHAHAHAHAHA. The hell cat had to roll up his window to get rid of the hideous sound of the S55 exhaust. Love it

😂 tony is right, worst sounding turbo I6 BMW ever. Still a stout powerhouse.

Damn impressive that the M3 hung with a F458 with only ~$2K in modifications....

Well it's a turbo motor. Honestly, the 458 engine is far more impressive IMO.

I get what you're saying though about a performance value.

hell cat race doesnt add up to me and i have the same mods.

What doesnt add up? The Charger in the original video is like 150 lbs heavier than the Challenger you raced.

[Andrew@activeautowerke]

Video i posted is a 650whp pure stage 2 car.

OH I see the OP video is supposed to be just downpipes on stock turbos and it walked away from the hellcat.
Was the M3 in the video you posted a manual or DCT?

[Andrew@activeautowerke]

not sure. But doesn't seem like its having any transmission lag so ill go with dct.

In the F80 race what key was the Helkitten using? there are 2 different keys.

Nobody is going to race on the valet/wife key.

Well it depends if the vid was setup or not

That kitten you posted may have mods lol... They gain a lot of power with simple mods that aren't that easy to spot unless you know what to look for. A 650whp ps2 S55 would $#@! all over a stock hellcat

A stock hellcat is no joke. I think you mean an aggressively tuned Pure Stage 2. It won't win on pump gas either.

idk if I'm beating stock cats in my 500 whp dct 135i with ease I think an s55 with PS2s would dump all over one.nothing suprises me anymore though bc some guys totally bs on whats done to their car and how much power its really making

Your 135i is also lighter and yet you did win if I recall in a recent video.

It's hard to tell what to believe as we have vids of two cars showing different outcomes. Tuning alone is a huge variable.

We saw a car on OEM turbos recently trap 124. This can range greatly too.
