Track Day at High Plains Raceway (Good News, Bad News and O Sh!t News)
bsimon replied to scannon's topic in Roadracing
Again, the photos make it hard to see the actual flow path, but I think Hank's spotted the same thing I have. Note that it's on the block side of the gasket, as well. Can you zoom in to one of those areas for another piccy or two? -
Track Day at High Plains Raceway (Good News, Bad News and O Sh!t News)

Hard to tell from the pictures, but pics 8 and 9 look as though there is a gas path between the cylinders at their narrowest point, under the gasket's sealing ring. I don't quite see the same in pic #7 or 8, but it's hard to tell. Once the gas is in the soft area, the next port of call would be the teardrop-shaped water jacket holes. It sure sounds like you're getting some crosstalk between cylinders. -
The weather sucks here in Colorado. Good day to pound beers and watch the 24 Hours of Le Mans.:cheers: To get you through the mid day Nascar break (yawn) on Speed Channel, I'm listing live feed links for Eurosport. Most are foreign language, so turn up Radio Le Mans First link, others to be added as necessary. http://www.justin.tv/freddy49barsa Update: It looks as though Speedtv will broadcast the live stream during the Nascar break (12:30pm EDT) on their website http://stream.speedtv.com/24-hours-of-le-mans

Been practicing Tulowitzki's signature. Can't seem to master it on a round surface.:jester: Seriously though, it seems all the web outlets claim "Official MLB" and "authenticated signature" and such. I'm just looking for experience of who to avoid. Excellent idea! You know, I've found that Blackhawk casino valets will find you a very safe place to park for nothing more than a spirited ride through their garage in the Seven. They seem to enjoy the "semi-permanent hearing loss" effect that the VX delivers so well in closed surroundings. (I do take the steering wheel to my room though)

Need to find SWMBO's grandson a signed baseball for his b-day. Any experiences with Internut vendors would be helpful.

9.5 X 15 Kodiaks = 10.25 lbs.

Chavtastic! :ack:

More like "if interior decorators drove Sevens..." This car should be classified "don't ask don't tell" :jester:

Run a mill bastard across it. If it sings and doesn't cut, it's something rather hard. There are very few hardened steel parts in the bell housing area. The only ones I can think of are part of the clutch cover and/or clutch disk. Not good things to have free range. :ack: One other thought; The bits might be flotsam scooped up off the road into the bell housing. Are there any openings that might comprise the clutch's security? I once found a 20P nail in the bell housing of my Mustang. There was only 3/4" opening in the front sheet metal enclosure.

Skip, I'm using 235/50-15 Yoko 032 on 9.5" Kodiaks. The OD is 23.7. The 032 has been discontinued, but the 048 has the same OD. Next time we get together, put one of my wheels on your car and see how it fits up. It's nearly the same offset as the CC wheel on Tom's car. Actually only about .1" shallower. The full set of Kodiac wheels was 1522 shipped. Actually quite the bargain considering that you can order any offset you want and have the ability to change widths and offsets in the future at minimal cost. Another plus is the Kodiaks are only about 10 lbs apiece. If you ever dent a wheel, Kodiak can ship a replacement spun rim for a fraction of the cost of a complete wheel. No affiliation, just satisfied customer...

If you have a synchronized gearbox, you probably shouldn't be shifting without the clutch. The balk rings and tiny syncro teeth will take lots of wear unless you take a good amount of time to match rpm between gears. The clutchless technique really only works well with face type dog engagement gearboxes. ie; motorbikes, Quaife, Hewland, Webster, etc. Truck transmissions are the exception. Although they are synchronized, the ratios are so close together (sometimes less than 450 RPM on the auxiliary box) that there is very little time needed to match the rpms. Tagging the clutch twixt gears becomes a bother and causes more clutch wear than it's worth.
-
Motorbikes are simple dog boxes. Dog boxes respond better to clutchless shifts by matching RPMs. In racecars, motorbikes, or big trucks with close ratio transmissions, this means you just lift the footfeed a tad to unload the dogs and switch gears. If your gearbox has a sequential shift drum, it makes the switch faster and more precise 'cause you don't have to stir the 'box between the gates. :driving:(I finally found an appropriate thread for this smilie!) Here's a good synopsis of the various procedures from the man himself, Bill Hewland. http://www.hewland.com/svga/help.htm

The best selection of motorcycle side mirrors on the planet can be found in the EMGO Filter and Mirror catalog. http://www.emgo.com/catalogs/filter-mirror-2010.pdf Most of the online discount motorbike parts suppliers can get Emgo products. Your local motorbike shop can probably order them as well. Most of the solid color and faux carbon selections are reasonably priced. The mirror elements are second-surface real glass bits, not crappy plastic. I'm using a pair of the the 20-97153/54 ersatz carbon fiber "Euro Style" mirrors on my car. I found them on e-bay for $25 a pair about 4 years ago. no affiliation, etc.

Just a couple of thoughts here... I pretty much have ruled out plate type propshaft loops for the Caterham. It requires engine or diff removal to install. Although a plate type loop could be engineered to perform the function adequately, it's rarely mentioned in sanctioning body rule books. You may need a special ruling from the scrutes to compete in some events. Typical loop requirements for various racing sanctions are very similar. 1/4" X 2" mild steel strap, 7/8"OD X .065 wall mild DOM tubing, or 1"X 2" rectangular tubing. Food for thought, the 7/8" tubing option would be ~25% the weight of the 1/4" strap.

Count me in. Right then...will there be snow machine parking available?

Tall w/clown feet: Caterham SV vs. Birkin?
bsimon replied to e043656's topic in General Sevens Discussion
FWIW...The SV windscreen is an inch or so taller than the S3. -
I got to thinking about it and went out in the shed and flicked on the parking lights. Evidently Jeff had already wired the indicators and wing repeaters to turn on with the parking lamps. Problem solved! I'll just tape off the leads to the parking lamps and install the e-codes as is.
-
Skip, I've got the standard Caterham 7" socketed headlights with parking lamps. Do the Bosch e-code reflectors have a provision for the parking lamp bulbs? It's not clear in the FM pictures whether the parking bulb socket is present or not. I had just replaced the OEM no-name H4 bulbs with Silvania Silver Stars. The difference was somewhat less dramatic than when I changed the bulbs in my Tahoe. Maybe it has something to do with the height above the roadway. I'm hoping the e-code reflectors will be more brilliant. Rob, As far as I know, all 7" head lamps are the same and should fit the Lotus/Caterham shells be them 6014 sealed beam or replaceable bulb types.

Ammo does seem to think that with aftermarket rods, everything is OK to 8500 on a stock Duratec crank. Sounds logical. I'm guessing that the USA Caterham 263HP 2 liter engine must have the rods and pistons swapped. Unless maybe the Mexican built (US) Duratec 2L has forged rods?? The Duratec head is really amazing. It requires little to no porting work to make it breath like a monster. To get the GM XE to breath at (only close to) Duratec power levels, there's 1.5mm of material removed from all the port surfaces and bigger valves are stuffed in.
-
The 260bHP Duratec in the R500 is only 2 liters. Instead of making the engine breath better they get the extra oats with an 8500 RPM red line and big cams. The 260BHP 2.3 liter Cosworth in the CSR only screws to 7500 to keep the long stroke rods and crank from emulating a hand grenade. The Cosworth is un-ported, however they do Extrudehone the ports to remove the flash and uniform the finish. I understand the pistons have a bit higher compression ratio as well. I imagine you give up a bit of torque with the 2 liter, but I'll bet it sounds real nice at full song.:bigear:

It seems that Al has a new ally in the great fight against global warming. http://news.bbc.co.uk/2/hi/south_asia/8487030.stm They are in talks right now and cannot be reached for further comment.

Assuming that the car is a Caterham, it's 15.5 inside and 12 outside on the starboard wing. The port wing is shorter and the angle is different. 13.5 inside X 11.5 outside.
