Yikes, this thing has 256Mb memory!! Mike, what do you plan to use the laptop for? If it just for a programmable system or basic functions, I have an old 486 I can "loan" you. I used it in the car for my datalogger running in DOS-mode and it served me well. It is loaded up with Win95 and Office but has only 20Mb memory and limited disk space, no CD and requires a power cord as the battery is a "door nail". I say "loan" because it is company property but it is old and definitely not in their inventory, but you never know if they will ever want it back, LOL. Let me know if you can use it and I will send it your way to try out. Again, I would not consider for primary use. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Most of my pics come from the turbo Buick forums. Those folks are insane when it comes to HP. One of our own Z-car owners, Greg Kring, also has 2 GNs. One is a 3700# street-driven stageII and he recently sent out an update. He drove the car to the track and it clicked off a 10.45 @ 131+ on ET Streets AND PUMP GAS. Says the car picked up both front wheels despite spinning the tires. With race gas it has a best of 10.06 @ 137 with only 19# boost . Thats 764 RWHP by my calculation and with slicks and 25+# boost, I will need another calculator . RickB, did you see him run? BTW, any news on your engine knock. Before you dive into the engine, make sure the distributor advance is not malfunctioning and causing severe knock. If you continue to run NOS and do not already have it, I would consider a knock sensor and some device that can retard timing or shut down the NOS if it detects knock. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Last Friday turned out to be a great day. I had dinner with a fellow Z enthusiast, I actually got to use my sunglasses in Seattle , and I got notice that my new laptop was ready to be picked up. Thinkpad T21, 850MHz, 32GB HDD, an incredible LCD with 1600x1200 resolution, DVD, yada, yada. Now I can carry a movie collection when I travel. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Anyone looking to do a twin-turbo SBC (Myron?) might want to check this out. This is a little pricey but absolutely the best way to go as you will never have to worry about cracking or leaking headers. The high cost can be made up by the fact that you would not need large or expensive turbos. A pair of stock GN turbos would do just fine and there are experiments going on now that have TT GNs with 2 stock turbos making over 800hp. I believe the total cost here would be less than a S-charger setup. http://www.turbobuick.com/bb/Forum7/HTML/005489.html ------------------ Scottie 71 240GN-Z Scottie's GNZ [This message has been edited by Scottie-GNZ (edited March 12, 2001).]

There are several turboZs out there who have gone this route. IMO, unless you already have all the components and are shooting for 400+RWHP, it is probably not worth it. Spend the money on quality bolt-on components because that is how a turbo makes power. Unles you can afford it or just want it, quality bolt-ons will net you more than a stroker. Focus on a quality programable system, upgraded fuel system, I/C and exhaust. Your biggest gain is from tuning. Remember, you do not bolt it all together and have it perfect first time out. A well built L28T with the right components and properly tuned can make serious HP. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Evan, there is a rubber ring, about 1" in diameter, that comes with the filter element. Make sure that ring is in position on top of the element as you put the filter together. ------------------ Scottie 71 240GN-Z Scottie's GNZ

My first instictive response is to say "grab it". Even if it is was made for a small displacement engine, it should still be very good. If you have or can get a pic, let us see it. If not, I say go for it. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Stony, very nice setup. Sure would like to see Mark do something with the one he has gathering dust. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Before I tell you what uses that turbo, I need to tell you that it uses 4 of those babies . It is used on a CAT 3524B diesel putting out 3224hp and capable of propelling the "vehicle" up to 64mph. Impressed? You better be, that sucker tips the scales 510,000lbs. Imagine cruising down the I-state at 55mph, in a Z no less, and have that puppy roll by you? ------------------ Scottie 71 240GN-Z Scottie's GNZ

Norm, not sure about a pure slick, but the Buick turbo boys use a radial recap with great success. It is a fully treaded, soft compound layered over a radial carcass, making for a nice street/race tire. I actually had a pair and used it a couple of times but did not get a chance to see how well they grip because I was having serious spoolup problems at the time. There are some big HP Buicks using them and like any product, there are mixed reviews, but it is a good price/performer. The only drawback is that they are heavy and sometimes difficult to balance. I would imagine with the slick, the retread will probably also be a little heavier than normal. ------------------ Scottie 71 240GN-Z Scottie's GNZ

I have one but it is missing one of the drive pins. If you can use it, let me know. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Apparently it is England. Trying to get the person who makes them to give up some information. Supposedly he charges 170 British pounds (where the hell is that key?). ------------------ Scottie 71 240GN-Z Scottie's GNZ

Spoke to the machinist this weekend and he apologized for the delay. Something about real, high-priority, profitable jobs coming in . Not that the adaptors are not important, but at our cost he wont be able to pay the rent. He expects to have them to me by the weekend. Pete, Craig, BLKMKG, Robert Duke and Mike Kelly. My records show I do not have a postal address for you. Please send (resend) by email. RyalC, you are in if still interested. I will email you tonight. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Mike, in looking at the pics from the URL posted by RyalC, I have a concern. I personally do not like the look of a 1st-gen Z without the front bumper, so I would want to add one of the fiberglass ones. Also, at the insane speed you will hit and my 120+ in the the traps, I feel a front dam is absolutely required. In looking at the pic with the nose tilted straight up, do you think there is clearance to add those pieces and have them clear the ground when tilting it open? ------------------ Scottie 71 240GN-Z Scottie's GNZ

Very interested in this. Assuming it replaces everything forward of the cowl vent, any idea how much the weight savings would be? Does it have the stock appearance? ------------------ Scottie 71 240GN-Z Scottie's GNZ

Tbuck, I have been using one now for about a year. Although I drove my Z quite a bit, it is not a daily driver so the cons do not bother me as much. I had a 3.70 LSD that went bad and did not bother to repair or replace it because the 3.70 ratio is too low for my purposes. I drag race my Z quite a bit with a low-revving, high-torque turbo engine. As an inexpensive replacement, I welded up a 3.54 R200 and it has been put to the test and is holding up fine. So, the pro, of course, is that it is an inexpensive replacement for a LSD, especially if you do some drag racing. The con is that with the spiders welded, there is no slip, so the inside tire drags on very slow turns and really shows its ugly head on U-turns. The car is also much harder to push if not pointed straight. There have been claims that the car understeers and I cannot confirm how bad because I currently have my swaybars removed. Keep in mind though, that a little understeer is not a bad thing. In summary, if your car is a peg-leg and spins one tire badly (this assumes you do burnouts or drag race) then it will suffice. If you understand the cons and can live with them, then it will suit you fine. If this is your only car and you do a lot of city driving, I advise against it. If you do it, be certain it is done by a professional, like a driveline shop. ------------------ Scottie 71 240GN-Z Scottie's GNZ

This datalogger was designed by a GN owner who is an engineer for one of the large Unix vendors. It logs at a phenominal rate of 18.2 frames per second and at that rate the buffer can hold 104 seconds. Drop the rate down to 9.1 and the duration doubles, etc. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Clint, I like your thinking, but I believe you are misinterpreting what you are seeing and that is understandable. Now, not only do I like looking at those graphs but I live and die by them and my engine lives because of them . Although the large text on the right appears to correspond with the graphs, they do not. They are the key parameters that I want to have always displayed. Each graph, numbered 1-5 on the left, has its function identified at the top-left. The range of each graph is on the right side and the current value (the vertical line) is on the top-right. Graphs #4 & 5 are LV8 (load value) and MAF and by pressing the 4 or 5 key I can change them to display any of the other parameters. The only O2 value displayed in the graph is in big text and the 749mV value corresponds with position of the vertical bar and it is a tad low. If you could have seen the O2s at spoolup, they would have been low too because I had the chip programmed for quicker spoolup. At spoolup, it reads the VSS and senses no speed but also senses the TPS open, so it leans out the mixture and retards the timing until it senses movement then goes into another mode table. That was not my spoolup problem however. I pulled the turbo off again and inspected the wastegate housing and the entire puck has a nice clean, even exhaust color to it, which is bad!!!! What it should have is a nice neat color in a perfect circle formed by the wastegate hole and the outside of that ring should be a different color. This means the puck was never seated over wastegate hole and the little boost I was trying to build at spoolup was just going pass the wastegate. Problem fixed and we will now see just how much grip 275 BFG DRs have. ------------------ Scottie 71 240GN-Z Scottie's GNZ

Stock GN pistons are hyper. There were a couple of reasons why I did not go forged but cost was the main driver. I do not race on the streets and NEVER run high boost with pump gas. I occassionally get someone foolish enough to want to try me at a light and just a quick 2-sec spurt with 17# boost is enough to have them searching furiously for that mystery radio station. I have a chip with a 16-pos thumbwheel and each position increases/decreases the fuel mixture 4%, so on the fly (like the SDS R/L knob) I can change my fuel mixture. At the track when I do run high boost, I run no less than 110-octane. The popular GN forged piston is a .030 TRW and I was advised by one of the vendors I highly respect to not use it. He does not even sell it. My other options were a ROSS or JE .020 that were lighter and would require rebalancing. Took me out of my budget. Everything before the piston para is what I mean when I say I focus on eliminating detonation and are things I would do regardless of which piston, as a normal recourse. ------------------ Scottie 71 240GN-Z Scottie's GNZ
