Re: Need More Light on da road

I think those are for the MkII Sierra... not the US XR4Ti, which is a MkI.

Re: Need More Light on da road

AFAIK, FMVSS (or is it NHTSA?) guidelines for headlights are based on candela, so (old) headlights are designed around a package of bulb/reflector/lens to produce a result within spec. A higher wattage bulb, by its vary nature, blows up that equation. A higher wattage bulb can't not be worse for oncoming traffic. I doubt you can buy such a bulb from a reputable manufacturer that isn't "for offroad use only."

LED replacement bulbs create a similar problem, putting light where it shouldn't be. Some higher quality bulbs try to mimic the light output of an incandescent bulb and they will do better. In my limited experience, what I've found is that LED bulbs create a brighter, whiter light but have equal or worse coverage. The whiter light tricks the eye into thinking it can see more, but really it can (maybe) just see better in a smaller area. The effect on other drivers probably has a lot to do with the design of the headlight... LEDs in my H4-equipped Saab still had a super-sharp cutoff that I was reasonably confident wasn't going to screw other drivers. LEDs in my $#!%^& F150 didn't change the stupid blob of light right in front of the truck. It was a very white blob, I'll give it that. (I put incandescents back in the Saab.... quality H4 bulbs still got light further down the road than the LEDs).

I'm sure everyone's situation is different... and so are their needs. Make city streets safer to navigate is different than country roads, etc. I have big ass Hella 500s with 100w bulbs (totally illegal) in the front of the motorhome, because at 55mph on a dark highway I might need 500' to stop.... I need 500' of light! It's a different challenge getting around downtown San Francisco or whatever. :)

Another thing to consider is mounting something like Hella modular headlights somewhere. The 60mm units are very small and they are full DOT headlights. You could theoretically mount them like driving lights, and just have state of the art projector headlights instead. On cars with "euro" headlights, lots of folks gut the incandescent parts and just stick a 60mm et al Hella in there. Unfortunately, not an (easy) option with crappy US sealed beam/composite lights like the XR/Scorpio.

Here's a link to the Hella 60s... $60 each.

Re: Need More Light on da road

There was a consumer reports article several years ago comparing headlights on many new cars, and the takeaway was that even cars with fancy front lights did an objectively bad job lighting the road. IIRC, the Prius was the only car they said had very good headlights. Probably that info is out of da...

Re: Need More Light on da road

While I really anti-endorse (illegal) high wattage bulbs, you can buy prefab high-amp headlight harnesses.... they connect to an existing headlight bulb connector, the battery, and ground, and voila, 14ga (or whatever) wire to your headlight... https://www.amazon.com/34265-9007-Headlight-Relay-Harne...

Re: T5 Clutch fork....

I'm reviving this thread, as I'm becoming less satisfied with the clutch feel on the car. It's absolutely fine for driving, but I think it might be too heavy for traffic.

Re: My first electrical problem

The connectivity issue doesn't appear to be at the bulb... at the taillights it was clearly the main connector just being an '80s design. I've run into the exact same thing on numerous '80s euro cars. The front turn signal issue is weird. I think it's splice S145 where all the turn signals come toge...

My first electrical problem

Took over 15 years for me to have my first actual electrical problem with the XR. After spending an hour going through wiring diagrams and checking the multimeter the problem appeared to be a bad ground on the right rear tail light. My quick fix: https://img.sacsaabs.org/xr/xr_taillightground.jpg I ...

Sheriffs aren't heads of law enforcement - they are local.

And your nitpicking doesn't change the substance of the point.

Re: Exhaust manifold damage

What those Superchips etc. could do really depended on the car. IIRC the ones for Mopar SMEC were pretty competent. For EEC, I agree, they often didn't do much. My recollection on the SHO was that it tweaked timing and moved the secondary runner opening point. I also had an '89 (no rev limiter, no s...

Re: Exhaust manifold damage

1000%. I remember talking to a Saab tuner back in the day and he commented that he could get +50hp with nothing but software, not even touching actual boost levels. The stock ECM was tuned for the big fat middle of the road, but he could tweak fuel and ignition to unlock a ton of potential in the st...

Re: Watching Hot Rod Garage tweek an '87 Turbo T-bird engine...

I really wish these things did a more incremental approach... the whole kitchen sink approach is fun and everything, but I wonder how much of that +100hp came from what upgrade. I remember a conversation with a Saab engineer once and he admitted they could get +50hp from an '80s Saab motor with just...

IMO a lot depends on the actual targets for this car. I feel like a lot of people get carried away with the credit card and bolt-ons etc. rather than following a good plan. In my mind, crazy manifolds and external waste gates are kinda Nth degree stuff. How much boost does this car make? How much po...
