Considering one for my wife and I know I won't be able to keep my hands off it.

What are these capable of given their curb weight and brick like aero?

I know there are quite a few 335s in the 11 second range, can the X5 find its way into the 12s with the awd advantage at least?

Well there's been some 335d that have gone below 12s in 1/4 with rwd. I bet you could get in the 12s with a delete, hyrbid turbos, and meth in the x5. If you did a cam and springs you could probably get even lower. Haven't seen many people push the limits on an x5!

Did 12.34 with BPC 2+ only
Stock turbo and no meth
With a poor 60ft and a poor xhp flash

Now on meth, Malone, lsd, slicks and freaking awesome Sutphin V9.7 tcu tune (5mph gain on the 1/8)
Aiming at 11's in couple of weeks

Thanks for posting up. I have to assume that's not an X5 though right? Everyone is saying just touching 12s is a pipe dream.

There's talk of a euro 335d touching 9s. Depending on how much you want to spend, I think 11s are doable for an x5d.

You’d really have to mod the heck out of a x5 35d. Most folks who are racing the e70s are using Ms. I’d like to the e70m forums for how to get those times down.

a stock X5m will do the 1/4 in 12.5 @112. But it has 555hp.. a tuned x5m will do the quarter 11.5 with 700hp.

I suspect a diesel with its short power band will take a ton to get into the 11s. Stock it’s good for about 15.6 @ 88mph. I’m not sure hybrid turbos etc would be enough to get in the 11s , since it’s not a big power increase from a 2+. Torque, sure, but the power band is very narrrow.

Completely agree and I have looked at the M gassers for an idea of what it takes power wise.

And while I agree about the narrow power band, that same power band hustles the E90 quite well, so it cant be that much of a lame duck. And honestly, as far as diesels go, the small turbo brings torque on hard and large turbo holds power to the shift fairly well from the dynos ive seen with deletes and letting it breathe.

I do think 11s would be a bit of a pipe dream for the Xer without spray or upgraded turbos minimum, but 12s would be a goal, even high 12s id take.

One I looked at that last weekend didn't fit the bill, so we will see even if we get our hands on one at all.

Personally I think it would be fun to see someone do this in an X5. The fastest 335d with probably 500+hp, was an 11.9 second car...

Assuming a weight of 5300lbs for the diesel x5.

You’ll need 485hp minimum to break into the 12s using a simple calculator. Hp is just torque multiplied by rpm and divided by 5252. Gasoline engines have higher volumetric efficiency as they can rev, so they can burn more fuel and air. Power is all about how much fuel and air you can burn. 3 basic ways to increase this, displacement, boost and revs (as well as changing the air it burns)

That solidly puts you in hybrid turbos and meth injection, upgraded fuel pump, etc to hit 485hp with an x5 (maybe). Smaller rims like 16s reduce rotational interia, and a diet lower that number... basically you won’t have a daily driver any more, and you’ll be nearly at the limits of what is possible currently from off the shelf parts and tunes. Of course if you make your own turbos, and push he engine further. But this car will be on jack stands as much as it’s driven.... ask me how I know ��

Use this calculator to give you a rough idea of what you’ll need.

I too would love to see this. Something about a diesel bmw being able to be just as fast as a twin turbo v8... 500+ isn't too hard to do just because the support for it is there... but the money and time you'll spend to get it there will be A LOT. Too much for me lol

[type-dRew]

I doubt i'll be pushing it to that limit, but I do have a dry nitrous kit in the shed, may give that a new home when we get one and just how much of a shot it takes to break a 12.xx with everything else basic bolt ons, meth and an upgraded fuel pump

Thanks for the words of advice guys
