When 555 HP is not enough!

by Obsessed MotorsportCategories BMW, X5 MTags , , , , , , , , , , , No Comments

I’ve been driving the ’13 E70 X5 M the last few weeks and been getting used to how it drives. As I drive the truck more and more, I start to appreciate what BMW M has done. Coming from an E53 X5 4.8is, the unofficial “M” vehicle, I notice a number of differences. Handling is incredible, so flat on turns, it’s sort of rediculous. The exhaust burble / overun is fun, though could use a bit more of it. The DINAN exhaust on the E53 is wonderful, the stock exhaust on the E70 is weak-sauce. I know a lot of it comes down to the fancy cross-bank turbo manifold muffling a lot of the intake sound, but it detracts a good amount from the overall experience.

Now, I realize, some of the big differences between the two may just be the 8 less years on the E70 or the 110,000 less miles, but the E70 feels more solid,and more well built than the E53. I do miss the heaviness of the doors on the E53, but this is just the picking of nits. Back to HP and my observations. I’ve noticed that from standing stop, the acceleration is super impressive, tons of torque, “down low” as they say, and lots of grip – great stuff. However, I’ve noticed at speed, say 40-55 MPH, I’ll downshift and while the truck will accelerate, the urgency from the motor, is not quite there. Maybe I got used to the responsiveness of the S62 in the DINAN S2 M5 (God that thing pulls), but the X5 feels a little flat. “Maybe it’s time for a tune?” I ask myself.

Enter Velos

I found Velos Designwerks on XBimmers forums. They’ve been around for a few years, there a number of very positive reviews for the service and their product and they’re fairly reasonably priced. Though, I feel like $900 is the right spot for a tune, but that’s me. They claim their tune adds 90HP and 120ft-lbs – good stuff, especially considering it is just software. I had to do cams, an airbox, headers and cats to get 80HP on the E46 M3 – sheesh! I’ve got their personal tuner platform on order and I am thinking about finding a local dyno shop to do a baseline of the X5 before I add some more power.

Keep an eye out for a follow up post as I have some additional upgrade plans for the 555HP family truckster. Including but not limited to:

  • Software
  • Exhaust
  • Guages
  • Downpipes
Why are the wiper nozzles not spraying?!

Why are the wiper nozzles not spraying?!

by Obsessed MotorsportCategories BMW, E39 M5Tags , , , , , , , , , , No Comments

Is it strange that out of my fleet of six cars; the M3, X5, M5 and E30 all have windshield sprayer nozzle issues?

I had the M5 nose up for a T-stat replacement, when I decided I would remove the fender liner to clean it up. I then remembered that now would be a good time to see what was causing the wiper fluid to pool on the garage floor and why my nozzles were not spraying fluid. Once I pulled the tired looking wheel liner off, I discovered the cause of tank leak, a busted pump was the culprit. It seems the pumps fail internally when non-BMW washer fluid is used.

Failed pump seal caused this to leak.

My mechanic cousin mentioned it’s because the non-approved fluid eats the internal seals. Incidentally, I was examining the under-hood insulation and noticed the part under the wiper nozzles was un-tucked, when I pulled it down, happened to discover that one of the hose lines that feeds the nozzles was cracked! Mysteries solved!

Broken hose

We wouldn’t be obsessed if we just installed an Autozone rubber hose. Nope. I need to make it more complicated! Turns out, you can buy an entire harness / assembly from BMW! This one was made in 2017! This should last at least another 17-18 years!

Part number: 61608364200

While I was in there, I added a new main pump, and two new nozzles, as I want to do  this job once.

DINAN S2 M5 Delivery Day

Up for sale 1-of-1 3 Series Wagon!

Up for sale: 2016 BMW 328xi Sports Wagon!

I have to give credit to my wife. She has unbelievable patience for my car obsession passion. In September I acquired BMW vehicle number 6, a 2013 X5 M (E70), which means something has to go. Enter the 2016 328i wagon, she’s up for sale.

The new addition is painted in Melbourne red, like the wagon, and came with 65k miles. Ian, the previous owner took good care of the truck and aggressively changed all operating fluids. All of them. Multiple times.

  • Engine oil
  • Transfer case
  • Front differential
  • Rear differential
  • Transmission
  • Coolant
  • Power steering

All of these have been done since 45k miles! Awesome! I’ll highlight the X5 M later. Back to the wagon.

So now I have a 328i and an X5 M. The wagon was meant to hold me over until the (F85) X5 M’s came down in price. I thought I would just keep the wagon as my daily, until the DINAN S2 M5 came along, so there goes that.

The wagon has been a great car! It’s fun to drive, is super unique and will be the last wagon we’ll see in the USA from BMW for a long time. I’d love for her to go to a good home. If you are looking for a one of one M Performance Wagon to spice up your life. Contact me. Obsessedmotorsport at google email.

The official post that has the wagon for sale can be found here: ’16 Melbourne Red F31 Wagon M Performance Parts

Replacement car…er SAV found!

Thank you eBay! You connected me with another obsessive enthusiast!

Guys, meet the new member of the family – 2013 Melbourne Rot X5 M! She’s got 65k miles and all new fluid! The previous owner changed ALL the fluid at 55k-ish, right before things get funky! Yes! Thank you! Plus, it’s got a hitch DINAN springs, and paint protection film – and yes mud flaps.

Here is a screen shot of the recent maintenance.

The next fun part is logistics. I’m going to fly to IN to pick it up. Then drive down to Knoxville for a Real Estate business meeting, then back up to New Jersey. Oddly enough, I found a decent pair of OE winter tires and wheels for sale in Cincinnati, which is right along the way to Knoxville. Good time!

I’m pretty excited about the new truck. I’m glad it’s got the LED headlights, color is cool too, as it will be replacing the F31 Melbourne red wagon. Next up are DINAN exhaust, downpipes and a lava blanket!
