YO!! Yeah, working too much lately, and hiding from the weather. 540 is clean and sitting now, thanks to the damn weather. Pulled in the LRS today though for the transmission swap.
Enjoy the skiing! Gotta make the best you can out of this wintery stuff...

Yeah, you guys got some cold hitting hard up there.
Looking forward to your LRS tranny deal and using someguys adapter! Good luck!

I'm planning on it after I get some more seat time on some of the local road courses. All the power in the world aint gonna help me much until I figure the chassis limits lol. Ordering a Stop tech ST 60 kit for the front, M5 rear calipers with ZCP rotors. Also need to finally pull the trigger on installing my oil cooler and replacing the stock lines. But while in there, I plan on doing the Eibach front sway bar and M5 Steering gear box with new lines. My to-do list is getting out of controlOriginally Posted by philly98540

Those brakes are not cheap. Putting some $$ into the car! Kinda needed for road courses though, so I see why your doing it. You will like the M5 box and sways. Really improves the handling. For you, getting the handling and braking are top priorities vs more power.

The Eibach sways are tops, they come with nice poly bushings too. I've got them on the front and rear.
Member
Yeah ive had the Eibach sways on my old 540i6. Did a full suspension overhaul, did BCs with swift springs, and M5 LSD all in one day. Car handled beautifully.
May need to look into either rebuilding my current BCs, or maybe hitting up Feal for a set of their race coilovers. I just wish AST made something better than their 2000 series for our cars.

I'm going with the Zinc coated slotted ones. Dont want the drilled, as they create points susceptible to cracking under harsh braking conditions, such as I see on the track. I'm also going to be making custom backing plates to cool them.

Nice to see some of you chaps pushing the vortech supercharger hard. My e34 is at 10psi with fmic. I’m still on the Porsche 803 maf with 1v offset and 60 lb/hr injectors, an adjustable for (set at 2.4bar)with a simple fuel interceptor computer. Tune is great it really comes alive at 12:1 a/f.
I have the fuel for more boost but are maxing out the maf. So will prob need more resistor on it.
Am encouraged that people are getting nice boost on the vortech si. The engine copes with 10psi real easy. It’s great to drive even in this form.
Is it doable / advisable to extend the rpm limit say to low mid 7s as this would also add boost.

With stock cams on the M62, it appears that going above 6800-7000 rpm does not yield much benefit. The boost will go up, but so will the heat and work needed to drive supercharger. With some bigger cams, over 7000 should be doable, but I'd start to worry about the rods. Maybe some of the scandanavian guys would know more though and could comment...
My MAF is also maxed, but the tune deals with it OK. I would like to resistor the MAF or upgrade to the 803 with resisitor at some point. Do you have the 803 MAF transfer function?

I use the 803 with a voltage offset (where the computer sees 1v less than the maf sees) and i still clock the maf at around tyev600 rpm mark. Was going to install a 330ohm resistor as others have done. With 10psi have got a pretty consistent air fuel ratio seeing 12.0 at peak rpm. . I’m using the factory ess chip with a simple but very effective piggyback fuel computer (silicone chip digital fuel adjuster) which effectively gives me 128 load points that I can either add or remove fuel. When I remove fuel it adds timing so in a way I can also make default timing changes by adjusting fuel pressure.
Havent dynoed it yet but at 12:1 on the 60 lb injectors at 2.4 bar (at idle) I’m seeing a comfortable 70% duty cycle. Before with the 30lb injectors needed around 4 bar fuel pressure which was not enough. I decided on the 60’s to give future headroom or perhaps e85 and I can use the excellent Siemens Deka injector which work great at low duty cycles and low fuel pressure.
As mine is m60b40 the cams are more agressive than m62 and the way it bangs into the limiter it feels 500rpm short. I think our friend from Finland (516sc) mentioned somewhere his rpm was 7750. I’m abit worried him blowing up a pair of 420g gearboxes. I guess drag racing on slicks the gearbox takes some serious load.
The setup certanly feels it can easily cope with upping the boost. Originally only thought 12psi but it seems that is a little short of the mark and I should be considering 1bar at minimum. I plan on doing a few track days so I’d have to keep it consiervative and look at the vortech compressor map is still in a good efficiency point not to generate excess heat.

How 'bout some updates my man!?!
We need to keep the fun, hotroddy threads popping on here. Gonna be 80 degrees here today, winter is over!

Yeah hot damn, finally it looks like old man winter is moving on. Actually frost on the roof this morning, so he was not going away without one last punch. Been just an aweful spring. We will likley go direct to hazy hot and humid. Barf. Anyway, been crazy busy with travel and home projects, so car stuff has been put off foir the most part. Just got back from a week in Switzerland (awesome place if you get the chance) and took the family to Utah, and Grand Canyon areas for Spring Break. Zion was our favorite.
The car has been rock solid all winter/spring. Not a single issue or wrench turned if my memory is good(?). I think I changed the oil. I'm looking forward to the higher temps later this week to see if the intercooler project has paid off when conditions stress it. Today was fairly warm and power was solid, but I want to see what happens in 90 degree heat. So far, I'm very happy with the W/A intercooler mod. As a next power mod project, I may go one size smaller pulley and see how it goes. I may run out of injector, so I will need to fire up Testo to see where my duty cycle is these days. I can up fuel pressure some too and tweak the tune so trims are happy.
I still have original center link and tie rods, so I may do some suspension work soon. I'm at 166k now, and some susp parts are still original. Drives good but the rubber boots are dying, so i know its just a matter of time. That deal on FSDs/Eibach looked tempting too.

Yeah, I'm so sick of being cold, I'll happily accept hot and muggy! You should be dandy in the heat now with your intercooler!

So been a long while since I did any mods on my car. Just been enjoying it and driving it almost everyday. Just crested 183k miles with original engine. So last week I noticed some rough idle here and there and then some odd swings in my afr’s on throttle transitions. Then CEL for fuel trims. Ugggg. Thought it was a vac leak or something minor. Then noticed excessive PCV oil in intake hoses. Today I disconnected the pcv hose from the SC’er intake and started it up. Lots of blow by coming out. Double ugggg. Removed plugs and did a compression test. Results as follows:
1 = 215 psi
2 = 215
3 = 215
4 = 220
5 = 210
6 = 210
7 = 95
8 = 220
i did 7 wet and got 160 psi.
So, it looks like a trashed a ring or piston in number 7! F!!!
Stuck my phone borescope in there and saw this:
9A396277-2D7D-4712-BE7B-CC066F2A1602.jpeg
From this it looks like I may have damaged a ring land or something. I’m not seeing any visible scratches in the bore, but maybe the camera just can’t pick that detail up.
I’m bummed but not super surprised as I’ve been having some good boost on this old engine for a while. Anyway, contemplating what to do at the moment.

Damn Chris!! But seriously, I feel like that engine doesn't owe you anything.
You're making pretty much the most power of anyone I know of on an M62 (of course others will CLAIM things, but never really demonstrate it), and you have been having fun with it at that power level for quite a while now. With that said, it's still a bummer compared to just continuing to rip on the undercover hooligan to your heart's content...
I think I might still have one good M62 rod and piston out on the shelf if you would like me to send it to you!?

Chris that's isn't a good Christmas present. The top edge of the piston doesn't look good.
Maybe a junkyard block if yours is trashed. There are a few in the local yard here.
Hi Thad, how's the LRS doing?

Hi Jim!! The LRS is a damn superstar, and is currently undergoing a few revisions to hopefully make it work more seamlessly next year with basically the same overall setup. Although I'm currently working on seeing if I can make a compact radiator for the front, out of an intercooler. Lol
How's your ride? Must be nearing full drivability? BTW, enjoy some sunshine for me!

Not to hijack Philly's thread but the '33 is moving along, slowly. Just got too many other things to do.....all new suspension bushings on our son's 4Runner. Also bought a new 60 gal compressor and put 240v in for it.

The weather has been pretty good here, only snowed 4" once and all melted the same day. My kind of snow.
In the last week I've installed the rear fenders, the running boards, and made an enclosure w/fan for the tranny oil cooler.
Don't ask why the fenders and running boards are red, I don't know. It's gel coat and came that way.

so what's the limit of the stock m62? can anyone summarize? I couldn't read 20 pages sorry
