03 M45 Hooning Tips Request

[ImpoRTninjA eLeat]

Thanks for stopping by, I just picked up an 03 m45 with 148,000km on it last week for 1.5k, currently im fixing the nav system unit ( theres a bunch of ruined solders ) to repair the video display on the console, ive got some rear wheel bearings on the way as well.

Speaking of that Nav System unit, why would they put a dvd drive that will heatup due to spinning a CD in an enclosed area with no airflow right beside an enourmous subwoofer. Wave goodbye to your Solders.

However I don't plan on keeping this thing for too long so I'd like to hoon it out before I part with it.

Im having a terrible hard time trying to burn out the tires, any tips on that would be sweet.
Any small fix to the lagged throttle response from a stand still?
Tips to get this thing sideways?

Welcome to the forum!
My 07 M35 had the DVD NAV and the unit was in the glove box. I never noticed much heat but I'm sure there was at least some. Mine never had an issue, but yours is an additional 4 years older so perhaps with enough years, they will all have trouble. I'm not sure what you mean when you say "hoon it". I'm assuming we brits would call it modifying it?
There are a few members here with Q45 models (1989-2006). Hopefully they will chime in with ideas.
Meanwhile, here is one of THE BEST videos of your car: https://youtu.be/vkuRMQOTbRw

Hooning ?

Had to google that one.

Hoon is a term used in Australia and New Zealand, to refer to anyone who engages in loutish, anti-social behaviours. In particular, it is used to refer to one who drives a car or boat in a manner which is anti-social by the standards of contemporary society, i.e. too fast, too noisily or too dangerously. In New Zealand, the term "boy racer" is also widely used. Another slang term, revhead—derived from "rev", short for revolutions per minute—is sometimes used in place of hoon. "Anti-hoon laws", while they generally concern road vehicles, sometimes also target anti-social behaviour in motor boats.

Hoon activities can include speeding, burnouts, doughnuts or screeching tyres. Those commonly identified as being involved in "hooning" or street racing are young and predominantly male, although increasingly female, drivers in the age range of 17 and 35 years.

Hoonigan
noun,see hoon or hooning: a person who participates in any type of reckless driving including but not limited to drifting, drag racing, and burnouts... See Chris Forsberg, Ryan Tuerck, Ken Block, Vaughn Gittin...

First, have you turned off the VDC (Vehicle Dynamic control)? this will keep the traction at the expense of acceleration, this among other "Nanny" controls kills the perfectly adequate power of this small V8.

Second try free flow exhaust to free up a little more power. Also I think the Engine management has a learned memory when I first got my car it would not spin the tires very well at all but after exhaust work and lots of relearn, including a battery pull over night for other unrelated issues it seems to have no problem spinning tires every time VDC is turned off

VDC button is nice when off but I still seem some issues with the traction control system playing with the tires. I'll be sure to try that battery pull trick. A straight pipe off the manifold would be pretty sweet, i just need to find myself some flanges.

Someone might chime in soon with some magic trick.

I have read too many vehicle manuals recently, so I might be getting a few things mixed up. If so, please pardon me... but IIRC, with an M45 the VDC system can be basically broken down into the engine management and the traction control part. Even when you push the VDC button, the traction control part is still active, albeit a little more subdued. So, yeah, in the right conditions your handy brake assist nanny will try to keep you in check.
Right conditions above in my imagination is that the car is reading engine speed, wheel speed on all 4 corners and the yaw sensors to know what the car is doing. For example, if you punch your throttle you can burn rubber all day and could probably lay some donuts too, but when you are doing 50 and try to slide around an on-ramp, you'll feel the lady taking control from your crazy a$$.

Talking of which, I can't think of hoonage without envisioning burnouts. Too bad you've got an open diff, and noone that I know has done anything about that on the Y34. Granted, the electronic manipulation from the factory did pretty well for a RWD like this, and even made for easy winter driving, it's just that hoonage requires a different level of dedication. A member here used a LSD from a G35/37 sport on his 06+ M45 and was pretty pleased with the outcome. I don't know how hard it would be to borrow some rear components from the Nissan Z or Infiniti G for yours as well.

After offering what I have for an answer to your question, here's an alternate suggestion: Get something else if you really want to abuse the car. Not because I love Y34s so much, but parts can be quite expensive for these cars. It's likely that you'll have more $ in it than you can get out of it by the time you're ready to move on after abusing it.

from my limited checking out my car I am fairly sure the 3.69 geared VLSD from the Z will bolt up fine, giving better gearing for burning out, full out acceleration etc. and will have a better semblance of limited slip diff as well. however the car nanny system will apply braking to the excessively spinning rear tire creating a electronic limited slip, albeit at the expense of brake pads though. I would also prefer a real mechanical LSD I like the idea of better gearing, the 3.03 gearing of the stock y34 ideally would help with highway cruising mpg but in town it actually hurts mpg as the engine has to apply more power to get the heavy car moving.

Isn't that the truth, I let my buddy take a rip in her during the first snow a few days ago, and he curbed her so hard bent the tie rod into this

So yeap, im quickly trying to unload it after replacing what costed me $150 for an inner and outer tie rod. Locally its hard to find parts for more luxury branded vehicles that aren't "premium" aftermarket, MOOGS brand outer tie rod for the m45 comes with a outer tie rod ball joint that has no codder pin hole or castle nut for hardware.


As for genes comment, a direct bolt in VLSD from a Z with the 3.69 would be so so so much better and cheap. True fact about the Rear Brake Pads, the wear is substantially greater.

[EdBwoy]

Damn man, that was pretty mangled up! Just so you know, I wasn't trying to jinx you. Are we talking of a bent wheel, front end alignment and possibly torn rubber components?
Granted, that could have happened to any other heavy RWD vehicle in the same conditions, but there are cheaper, lighter and more hoonage-friendly platforms out there.

It seems a good portion of the y34 rear was borrowed from the Z (suspension and driveline). Gene, are you thinking that the electronic braking will still interfere with the VLSD installed? Or are you guys just pointing out a disadvantage of the current (unadvertised) electronic LSD?
The car mpg is already laughable, but hey burnouts don't come cheap.

ok here is what I am thinking.

Currently we have open diff with 3.03 gearing, as I said great for low rpm 80mph cruising, but s*** for acceleration and in town driving. the current electronic slip system will grab the spinning wheel forcing it to stop and transfer power to the other. which works after a fashion but hard on the brakes. The VLSD system the Z uses is a viscous gel like material that as one tire spins faster then the other heats up and causes the gel to expand then "locking" not really the right word but close enough, both wheels together I don't anticipate any problems with swapping the Z diff in because the electronic control we currently have goes by the abs sensor, if both rear tires move at the same rate no brake action is required so if the lsd diff is in both rear tires will be spinning equally.

Though a true LSD would be much better because as I said the VLSD does require one tire to turn faster heating up the gel, depending on the point of the current electronic system it may keep it in check using electronic and the diff does nothing. but I doubt it especially on hard throttle. and yes you will still have the nanny system protect you from some things as the front and rear brake will be applied to keep your a** on the road but you can still kick the rear out a bit. true dougnuts are not really possible with the electronic limited slip we have, the system takes over and you get notta. I have tried it got one spin around and done with the entire system off you could do it easily but one wheel peel keeps it from sliding sideways.
