Hey Ken.

I'll weigh the mini, but I will have to get out to my mechanic's barn to weigh the bosch. I'll tell you right now there is a big difference.

I have a solenoid that I bought around here somewhere, so I was temped to do a rebuild on the starter itself locally, but these are nice.

OT - Yep, I have to print out the directions - I think they are on wrong. These are the 16V ones you sent a couple weeks ago. They fit great and the stainless hardware is a nice touch. If you look closely at the engine you can see I like stainless.

did you guys have to orient the flanges on the starter to fit correctly? mine was not set up right at first,and ended up with the power terminal pointing down. BUT, it is recessed compared to the swaybar. On my first try installation, it fit, but it was the lowest hanging part on the car. I tried to justify, but after talking to Mark A, i decided to change the flange orientation. (good idea. NO, GREAT Idea!!)

also, the weight feels much differnt, but put them on a scale. new starter is only 6-7lbs lighter. feels like more!
Now, with the new bell housing, i also dont use that steel bracket to mount it, it mounts directly to the bell housing. (thats 2 more lbs saved!)

Hey Mike,
Good to meet you last week. What do you think of our fan setup?
Pretty slick huh!

mark kibort

Did i hear you say "FAN"??????

Ok, lets hear about it.

By the way, did you know that we got some of the Nascar guys are using our eRAMs as brake cooling devices? some even are using them for actve aerodynamic aids .

as far as radiator fans, i finally removed the S4 fan computer and used two relays for redundancy, extra flow when needed and power conservation.
one relay runs off a standard old model 928 thermostat, and the other runs off a separate switch. I also have a power off swich for the standard thermostat so it doesnt come on when the engine is off. What does your set up look like now?

This will be a very cool (maybe very expensive) project. If the whole point is to shed the weight in areas that are invisible and still having a fully functional car you'll have to reduce the weight of the current parts? How many parts can be deleted, drilled, held on with half the bolts or have lighter weight replacements?

If you've ever pulled out your seat you know how heavy they are. That would be my starting point. I think you can get 60-80 right there. Maybe replacing the gas tank with a small fuel cell? The bumpers are heavy maybe there's something that could be drilled out or removed (then a parking lot tap could total your car). The glass is heavy, but that would be visible......

I think you can do it!

mark kibort

sometimes the bumper removal can actually be good for the light accidents. without a bumper, especially in the rear, the plastic just has enough strength to absorb quite a bit of force, and distorts on contact. (see andersons major hit at sears, laguna, lasvegas. ) the cover never needed replacing. and barely got scratched on some of the hits.
as far as fuel tanks, have you weighed a stock tank?? its very light. actually lighter than most fuel cells
(except for the fact that you can remove a lot of steel back there if you do mount a fuel cell, so the net may be ok. but you can remove about 20lbs or so of steel if you cut out the battery box and cover.

Hi Greg, I was thinking the same, I will reduce the weight mainly through the use of carbon fibre. Things like the sunroof and rear hatch are a good start. (12kgs)For a street car I will leave all glass intact. The hood lining (the backing) is also heavy and you should remove the spare wheel, run a punture repair kit. All the internal sound deadning, lighter exhaust, GT3 seats, I'm waiting on this one as the new GT3 may have a even better seat. Make the B/Bar reo from carbon. Save 15 kgs there if you have an early car.Carbon Torque tube, save 10 kgs, I don't think it will be that difficult a job.

Nothing wrong with our tank BTW, The engine in my case will have to wait but you could save 15 kgs also. I added this all up last night and found after adding the PSD setup dry sump and a carbon undertray splitter diffuser I could theoretically save 110 kgs. It would give me a dry weight of 1380 kgs, the same as the new Carrara GT.

Mark, what kind of battery do you use in your Red Shark?

gruffalo

I have a custom exhaust, (SS), 911 style seats (very light), no AC, no headlight washers, no tools, no spare.

It weighs in at 1400 kgs.

I was thinking about making a carbon fibre roof, like the BMW CSL. That would give some more headroom and it would be lighter that the stock roof, do you guys think it's possible?

Hey Marc,
It was good to meet you too! I'm glad I was in the area to come by personally.

I don't think I can find any better words for your fan setup other than "BAD ***". The second I saw you pull it out of the box, I knew it was going to be worth every penny. The picture posted on the rennlist christmas specials page can't come close to doing it any justice. It is a very solid unit.

I had it installed the next morning on my car. The fit was perfect and very simple since only 2 fasteners are needed on top. I actually had my top oil-cooler line off (not sure if it would have blocked the install), but the unit basically just slipped into place on the devek radiator.

As far as driving and cooling performance, my car used to run between mid and upper line. Now, it runs between lower line and mid. I thought both of the fans were a little loud at first, but now that i've been driving around with it for a week, I don't really notice it.

As far as wiring, I already had an ignition-on signal wire I ran for my previous electric fan setup. I used 2 separate fuses and 2 separate relays. It was very simple and straightforward.

This weight question is so common to this group that it seems there should be a "click here" link of it all compiled. Sound deadener - 75 pounds. Front bumper bracing - 35 pounds. Exhaust - depends what you do - an easy 50-60 pounds. Seats of course. 14 pound battery. Do the Fix-A-Flat spare. Go through the entire car replacing non-stress steel nuts and bolts with aluminum. From what I have oft read, it seems about 200 - 250 pounds is the most that can be trimmed of - while still maintaining all options, creature comforts, noise levels etc. After that, it is the racer's work (gut out interior, ac/heater removed, could go non-power steering and brakes. Replace floorboard with alum or graphite. Redone fuse box to save 25 pounds or so... and it becomes a $$ question. For example, titanium exhaust pipes would save weight - at about $25 a foot.

Tass 928

I deleted my front bumper and shocks. In the rear I made brackets to replace the heavy bumper shocks then I drilled 8lbs worth of holes in the bumber beam.

net loss on the fuel cell was 11lbs.

Mercedes-Benz drilled holes is the chassis of their cars(shaved about 200kg(400lb) from SS to make it SSL I belileve). Can we do that to our cars?
