On the HSR? Its runners terminate flush with the base of the plenum. The reason the tests show more power with a plenum is explained by the influence of Helmholtz Resonance on cylinder filling. Using the aftermarket throttle body on an HSR plenum may influence the Helmholtz Resonance to whatever extent that volume of the plenum changes. An individual runner intake with four of these throttle bodies would be a different matter. .

The accessories at the front of a stock L98 engine present
some obstacles for unconventional routing of inlet air to the throttle body. Also, although not shown above, the master cylinder is adjacent to the #1 & #3 runners. Nothing impossible to overcome, just more head-scratchers to solve along the way to completing such an undertaking ... .

C6 owners interested in datalogging vehicle parameters
may want to look into an interface that enables data from OEM sensors to be logged along with GPS position, accelerometer loads and input from any external sensors that a user has. The interface consists of a cable that plugs into the scan port of the vehicle and runs to the datalogger. Hook-up is plug-and-play. Here are the parameters that are drawn from OEM sensors by the interface. 1. Engine RPM 2. Throttle Position 3. Throttle Pedal Position 4. Oil Temperature 5. Water Temperature 6. Transmission Temperature 7. Intake Temperature 8. Battery Volts 9. Wheel RPM (all four wheels) 10. Yaw 11. Torque 12. Horsepower 13. Brake Pedal Position 14. Gear Position Vehicles like my C4 with ECM/PCM that DON'T support this ODB interface require require hardware to be purchased and mounted to log inputs beyond the system defaults. Even finding a suitable source for the default RPM capability is sometimes a challenge and may require a third-party signal conditioner. Other external inputs can cost $200+ per channel. However, for less than the price of three external sensors (and none of the installation drama), folks with the C6 platform can just plug in the new interface and receive 14 channels. Of these, the wheel RPM & Yaw inputs are particulary remarkable because they present more challenge and cost to implement through external sensors. Here is a link to a document from RacePak. It mentions a contact person for further details (pr aht racepak.com.) The go-to guy for my G2X questions in the past has been Tim Anderson (tim aht racepak.com.) .

Want to learn a new skill or pick up fresh techniques for
additional enjoyment with an existing hobby? Take a look at the technical videos available from SmartFlix.com. I've rented several of their DVDs and have been very satisfied with the service, product condition and policies. Since I am an international customer, their domestic free return program does not apply - but the upside still far outweighs the downside. Has anyone else here given them a try since I posted about them before? Are there other technical video services like SmartFlix that you've had good results with? .

My vote is that an engine with a 3.75" stroke won't be a durable, reliable powerplant if it is roadraced to 7,500 periodically. Piston speed at 7,500 RPM for this combination is 4,690 feet per minute. It is high to begin with and there is no margin for mishaps. Miss a shift or overrun on a downshift and see 7,800 RPM? - piston speed rises to nearly 4,900. If you want durability and do not want to be frequently inspecting and maintaining the engine, then aim for a red line of 7,000 and have HP peak several hundred RPM below this. Otherwise, if 7,500 remains your goal, then choose a shorter stroke to bring piston speeds down at this RPM. .

An ice shelf is an extension of a land-based glacier
reaching out over an area of water. In the case of the Ward Hunt Ice Shelf in the arctic, it extends off from the coast of Ellesmere Island. Read more here: The Calving of the Ward Hunt Ice Shelf Background map courtesy of The National Atlas of Canada 5th Edition. Ditto for ice shelves in the antarctic, such as Larsen A,B & C. The speed of the break ups has been very unsettling for shelf watchers who have acknowledged that earlier models predicting far slower rates of decline failed to take into consideration several aspects that are now recognized to accelerate the progress of collapse. .

I didn't take the video as belittling the issue. We've discussed the ice picture here before and the view from some quarters is that change happens as part of the cycle of ebb & flow. Arguements have been made that the pendulum swings and the ice will be back. Seeing developments like these in the Arctic and those occuring in the Antarctic ice shelves have certainly been capturing my attention. While I have been influenced by the arguements from scientists who make out the causes to be climate change arising from mankind's dredging up of long buried carbon sources for use to fuel the present lifestyle, I have time for those who maintain otherwise. Regardless of the causes, the apparent consequences are daunting. .

heard the message aimed toward women promoting regular examinations for lumps. But what about men? Cancers of various kinds are a leading cause of premature death - many can be treated if discovered early enough. Yet, there is nowhere near the emphasis on prompting men to be more proactive as there is for women. That is beginning to change.

Further to news reported in late July, the extent of the
ice loss has proven to be greater than initially recognized. Canada's Arctic ice shelves break apart, drift away OTTAWA (AFP) 2008-09-04 Two ice shelves in Canada's far north have lost massive sections since August while a third ice shelf now is adrift in the Arctic Ocean, said researchers Wednesday who blamed climate change. The entire 50 square-kilometer (19 square-mile) Markham Ice Shelf off the coast of Ellesmere Island broke away in early August and is now adrift, while two sections of the nearby Serson Ice Shelf detached, reducing its mass by 60 percent or 122 square kilometers (47 square miles). Ward Hunt Ice Shelf, which halved in July, lost an additional 22 square kilometers (8.5 square miles). "These changes are irreversible under the present climate and indicate that the environmental conditions that have kept these ice shelves in balance for 4,000 years are no longer present," said Trent University's polar expert Derek Mueller. Canada's summer ice shelf losses now total 214 square kilometers (82.5 square miles), which is more than three times the area of Manhattan Island, the researchers said. Extensive cracks in Ward Hunt, the largest remaining ice shelf, means it will continue to disintegrate in the coming years, said Luke Copland, director Ottawa University's cryospheric research lab. .

The SBC and BBC had their fuel pumps positioned at the
front passenger side since day one. The routing of L98 fuel lines replicates the path used for the previous carbureted generation(s). The path for the LTx marks the first significant revision since the Chev V8 debuted in '55. A lot of cars, trucks, commercial vehicles, boats, and who knows what else have operated for their entire existance with the fuel line configured to run near the block and exhaust. Fuel line maintenance is not given sufficient consideration on North American vehicles. I am unsure of the reason, perhaps OEM materials and environmental/operating conditions enable NA fuel lines to last longer? Euro car enthusiasts in the know make a point of replacing flexible sections of fuel lines on a 7-10 yr basis. Early C4s have now been in service for up to 25 yrs. Tick, tock ... Gasoline possesses a significant amount of energy and there are no shortage of videos depicting the consequences of a fuel fire. The typical enthusiast is often under-equipped for fighting a fire at home or on the road. Hazards from a fuel line leak may be compounded by the quantity of fuel in the tank, gravity, siphoning action and the difficulty of accessing locations for leaks. Fire caused by fuel flash-igniting on hot adjacent surfaces may be momentarily extinguished only to re-ignite when more fuel siphons out and contacts still -hot surfaces (or is ignited by sparks from electrical wires whose insulation has been compromised.) There may be little left of the vehicle by the time the firemen arrive. If the car is in a garage, a vehicle fire threatens the building, contents and occupants. .

Do not take chances with fuel lines. The C4 L98 lines run
adjacent to the passenger side exhaust manifold and the flexible hose segments are near #2 exhaust port. A fuel leak at start-up of a cold engine may not ignite if discovered quickly, but my vote is that a fuel leak on a warm engine has a high likelyhood of igniting. On an engine that is working (road/track) it is a certainty. The rubber sections of the OEM hard lines have collars swaged into place at the unions where the rubber and steel lines meet. These unions are similar in appearance to power steering lines. A first step might be to check whether replacement supply and return lines are available from GM. If not, then check aftermarket sources like Classic Tube - they list FI feed and return lines in either OE or SS styles for 89-90 C4s. I am unaware of whether field repair of these OEM types of unions is possible. Presumably, there may be local industrial hose firms that have the equipment to do so, or perhaps national firms might offer a rebuild service. Alternatively, it may be possible to use products such as Aeroguip's Versil-Flare Flareless AN Tube Nuts and Ferrules to modify the existing lines to accept a section of braided hose to replace the OEM rubber hose. (Note that bend radius of SS braid may not be adequate for this purpose.) One requirement for this approach is for there to be tube nuts and ferrules available in the correct size to fit the metal portions of the OEM fuel line. A different, more common approach seen in the past is to use Metric-to-AN adapter fittings to replace the supply & return line sections. The OEM sections that run from the fuel filter under the passenger footwell forward to the L98 fuel rail are removed, adapter fittings are installed in the OEM fittings and then hoses with AN fittings are used to complete the supply & return fluid paths. .

But then I'd need a place to rest the bottle and some friends to share it with. As it happens, refreshment is something that is never lacking at the neighbor's. They run a home-based business and distribute imported wine around the province. The nature of the business means, or at least meant, a lot of entertaining. The summer barbecues next door have been cut back in the past couple of years. Last night harkened back to the days of yore. On such nights there isn't much hope of going to bed at the usual time. The options then are to call the cops to shut them down, sit and stew at home or go over for the food, beverages and society. Turns out that the photographer was responsible for the chair placement - he thought it would make for a great setting. Like I said, myopia was to blame - usually a good photographer doesn't fall into the trap. The thing about our yard is that the neighbors on the other side built an addition onto the back of their home several years ago. Changing it from a rectangular shape to an 'L' shape with large windows in the new addition facing across both back yards. Great for watching the summer sun rise over the trees in the morning - provided you ignore whatever project happens to be underway in Slalom4me's back 40. Man, they've lived there long enough to know better. A wedding for one of their children was held in the back yard, too, come to think of it. Because of past history, I was less inclined to make a contribution in that instance. Hope everyone's done for the season because I've got some projects coming home in a few days. .

We have some neighbors with whom we have what I consider
to be an ideal relationship. While we exchange pleasantries and help each other out when things come up, generally we each go about our business independent of the other and don't spend a lot of time on one another's patio. Well, they held a backyard wedding for their first born today. Knowing that the wedding was approaching, I caught up on routine yard work and added some extra brushing around the perimeter. Put some things away and built a lattice fence to obscure work in progress on a shed. It made for a nice improvement but didn't take care of every detail. Call it a twenty-footer, squint and everything looks fine. All in all, I was content that I'd done my part to help. This morning I look outside to see that someone at the neighbor's place had set up the guest chairs - they were all facing our house. I am sure it was a classic case of myopia, all they could see were the trees along the property line that would nicely frame the ceremony - failing to notice the pile of project lumber and off-cuts in the background that would stand out prominently in the photos if it remained there. Some hours later, the view was improved. Wedding has gone off smoothly. Guests have eaten and now I hear the band playing - time to go enjoy the entertainment. .

Anyone taste Guinness from bottles?
Traditionally it has been available here in cans, but recently it was available packaged in bottles. In fact that was all the store had on that occaision, so I wound up trying it. .

No, these are different. Sleds are rated for upwards of 100-120 HP - in several situations they are called upon to make it and this produces heat that has to be dispersed. Three examples of the many configurations . .

The original application that prompted the thought is
liquid cooling systems for snowmobiles. A plethora of shapes of exchangers are mounted in the tunnels and under running boards of sleds. Some of the large displacement sleds have several discrete kinds of exchangers scattered around the underside. With the variety of exchangers, there are an equal number of methods of connecting coolent lines. Ideally, a suitable unit with an fittings would turn up. However, keep in mind that these are extrusions - it is does not require rocket science to cut, weld, join relatively thick sections of cast aluminum. While I would want to test to see what kind of pressure drop occured when intended for engine oil requirements, I am more than confident that flow would be adequate for transmission purposes. What I have not found is anything that gives some insight into the heat transference properties of such devices. A search brings up sources for new and recycled exchangers ranging in price from sub-$40 to plus-$100. .

A frequent issue when tracking vehicles is that of elevated
fluid temperatures. Various styles of oil-to-air and a few oil-to-water types of exchangers are available to help shed the additional heat. Something I have not seen in use are the extruded section fluid-to-air coolers. The reduced efficiency of this style (versus tube/fin/plate styles) is offset by the possibility of choosing coolers with greater surface area and of mounting them in non-traditional locations, keeping heat load off existing coolers in traditional locations. The extruded sections are very durable and impervious to debris impact. They do not rely on airflow through tight passageways and thus are not subject to clogging. Typically the ones I am familiar with are under 1" thick, a few inches wide and deployed in varying lengths. These can be joined in series &/or in parallel to increase total cooling surface area. The shallow depth section opens up several possibilities for mounting. .

Aeroquip offers A/C hose and fittings. I do not have
first-hand knowledge of someone using this material to replace OEM C4 lines, but it is used in the custom car trade. The hose is sold in three diameters -06: FBF0600 (bulk) -08: FBF0800 (bulk) -10: FBF1000 (bulk) It is also available in cut lengths of 3', 6' or 9'. Replace the (x) with the desired length to determine the appropriate p/n# -06: FCF060x -08: FCF080x -10: FCF100x There are straight, 45º, 90º and 135º fittings. All but the 45º are available w/wo a charge port. .

I cherry-picked my vinyl and gave what I didn't want away. In addition to what I'd purchased on my own, I inherited two generations worth from relatives which I continue to hold. I have three turntables that are ready for action when I am in the mood. Just this past Saturday, I was listening to a new CD when it slowly dawned on me that the engineer had added LP-like snap, crackle, pop 'noise' between tracks. I bet there are many who won't even get the joke if they notice. .

Thanks for the suggestions. I'll look into the devices
mentioned. I've stayed away from digital because of the perception that it consumes more time & resources while offering less convenience and durability - compared to disks. A fresh high capacity player would serve my needs until such time as music is no longer available on disk - I suppose that would just increase the number of disks that would need to be converted. .

My cd player w/ large capacity carousel is kaput and
choices for a replacement appear to limited to several -year-old Sony and Pioneer models. I suppose the species is obsolete and the mfrs have moved on. What is the best/least painful method to transfer hundreds of CDs to digital format, assuming I make the move to the MP3 world. .
