Well actually there is a 2”  flexible heater duct made out of something that resembles paper and a metal spiral.. It is probably all deteoriated by now. That is the only thing I know of .

·         Fishing through heater ducts - 1 Update

David Hale <astrono...@gmail.com>: Sep 08 10:25PM -0700

In the original ElectroAuto kit they had you fish a number of cables through the driver's side heater duct, from the engine compartment to the old fuel tank compartment. I don't remember this being particularly difficult. I'm running additional cables now and need to use the heater duct on the passenger side. Is there any reason why this should be different? I've been struggling for 90 minutes now and haven't gotten one thing through. I got a fish tape through pretty quickly but my cables got stuck on something. Eventually I reduced cables until I had none, and my fish tape got stuck on whatever this something is. Is there something in there? Any suggestions? I need to run two 2ga cables and two 1/2 water hoses (7/8'' OD). Thanks, Dave.

You're saying there are flexible ducts inside the duct in the floor? I'm talking about the short span from just behind the seat (in the engine compartment) to just behind the speaker. Flexible ducts connected to these ends, yes, but you think there were ducts inside this conduit? There didn't seem to be any in the driver's side.

No, they were outside the ducts. Try a stiffer piece of wire to pull your cables through. That's what  I used. Keep at it and find a friend to help.

ok right, that makes sense. I'm definitely hung up on something inside. I may invest $23 in a USB endoscope if I can't get through tonight.

Wrap tightly in tape, and create a taper. It will work.

I would not call Rotorooter or get the sewer snake out just yet.

 I've been driving my 914 conversion for the last two years. It's pretty much my daily driver. I've fooled around with the brakes and it still doesn't stop fast enough for my taste.
 
I've added 660 lbs. to the car as I'm using lead acid batteries. Does anyone have any suggestions? I've considered powered brakes, brake assists and racing brakes.
 
Thanks.

It's been a long time for me to remember details, but I replaced them with BMW brakes.

If I recall it was pretty much a drop in fix, and it definitely helped make it feel more like a 'real' brake.

this has details:
http://www.pelicanparts.com/techarticles/914_BMW_calipers/914_BMW_calipers.htm

I did the BMW calipers, new rotors, brake lines and 19mm master cylinder - everything that anyone suggested could make it better - and it did. I couldn't imagine driving again with the stock setup. It terrified me.

Cheers

Hi David,

I used the BMW brakes on my V1 (lead acid) conversion, but moved to 911 brakes (much bigger calipers with vented rotors) on the v2 (lithium) conversion.  Both are bolt on conversions, but the 911 brakes require 5 lug wheels which my car already had.

I never drove the car with stock brakes after either conversion, so I can’t really say what the comparison was in stopping power.  The BMW brakes did seem pretty good with the lead pack.

On a gasser I own and race, I could push on the brake pedal with all my might and still not skid the wheels (no antilocks in front) or get the antilocks to kick in (antilocks on the back). I know the antilock system worked because it is obvious it engages on ice. I swapped to Hawk HPS brake pads. Wow, what a huge difference. Now I could get full braking force with much less pedal pressure. They dust like mad (despite their claims to the contrary), but it is totally worth having to clean off dust once in a while.

Less likely an issue, but just to be sure, are you sure your brake pedal is not hitting the floor? Bad brake fluid can be spongy enough the pedal goes to the floor and you get mediocre braking. It would be a good idea to flush your braking fluid. I use Castrol SRF. It has very low compressibility and the brake pedal now stops half way like stepping on a brick -- very nice! Unfortunately it is $90 USD/liter, but you don't need to do it very often unless you do road racing (at least yearly and sometimes as often as every race then).

Unlikely, but easy to check, is for swelling brake hoses. Have someone step hard on the pedal while you look at the rubber brake hoses and make sure none of them swell under pressure. I have read claims that braided brake lines prevent virtually all swelling and make for a firmer brake pedal.

Since the 911 is a rear heavy car, and the 914 is a balanced mid-engined car, did you notice the rears tend to skid? Did you put in a brake balance device?

Just FTR, I rebuilt everything on my conversion (LiFePO4), including 
larger master cyclinder, hoses, new calipers from PMB, and a used 
stock brake pressure regulator. Pretty much stock.

My brakes feel sure, strong, and I have no creeping dissatisfaction
or desire to upgrade.

No, it really doesn't skid at all.
 
Thanks to all for the opinions.
