The PRofec reads I'm making boost, it sounds like I'm making boost, and when I lift, the HKS BOV tells me I made boost, but the power is not there. Sometimes that car barely accelerates when all signs say I should be. The car just feels like it's sick. Tonight after 15 minutes of retraining the PRofec, and boosting to train it again, I popped the cover, and my turbo was glowing. I had previously checked hose connections and BOV adjusting screw, thinking I was had a leak somewhere. Is the problem the glowing turbo, or is the glowing turbo the result of the problem. I can imagine getting nothing but hot air, and having the timing retarded so much I lose most of my power. Does anyone have an explanation for this?

Is is the volumetric ability of the turbo? Air + Fuel == Power Contrary to popular belief : CFM != air mass, PSI != air mass mass = volume * density volume = CFM Density is mildly correlated to pressure (i.e. for a higher pressure, there will be a greater density IF temperature has not gone up, why intercooling is so important) That being said, 2 different turbos output different amounts of air, which means the resulting power output will differ even @ same boost levels. Proper turbo selection is essential. FWD Integra GS-Rs turbocharged are turning 13 second 1/4 miles on street tires w/ no LSD. This is roughly @ 7-10psi.

Here is a short summary for those who did not read the web page. The text is copied almost exactly from their web page. Don't blame me if it's wrong! I sent them and email asking for price and other specifics. I'll try and post their answer to the list. From what I gather the main purpose is to eliminate turbo lag which should only take a few seconds. - -Activated by a micro switch and spools up to approximately 40,000 RPM, generating boosted air at 4 PSI - -once the stock turbocharger spools up, its boost is added to the 4 PSI - -automatically switched off by means of a pressure switch, when the boost level reaches a predetermined setting and air is once again fed to the engine through the by-pass air duct. - -As an approximation, power requirement of Turbopac for a given engine is less than 25% of current draw of the starter motor for that engine. Considering the fact that typical run time of the unit is less than 4 seconds, it is obvious that the vehicle electrical system is adequate for installation of Turbopac. - -Mass flow is 6 pounds/minute >Steve Bagdon wrote: >>Greg Wong wrote: >> >> Matt Ledbetter [Mattled@webtv.net] pointed me to >> http://www.turbodyne.com/ (see the technical section) >> They make electronic superchargers that can be mounted on turbo cars! >>What do you people think about them?

It looks alot like the stock system except the tips are removable and larger. The pipes and center section are stainless. The sound produced is slightly deeper and it has more resonance. It mounts much like stock except there is no mount in the middle of the center section, as on the stock muffler. A good price for one would be around $500. There is a distributor in Miami, FL, Select Sales Racing. It's a well built unit with a good price. I am running one on my 93T.

The brushes aren't brushes in the normal sense, but metal protubences that through springs are constantly on the shaft and generating the electricity. The problem is as you add the miles/kms the brushes become shorter and shorter. Eventually they get to the length that the spring(s) cannot force enough pressure on the shaft to generate the right volts/amps. My brushes, after 135,000 miles, were 75% worn. This, I suspect, is the cause of 90% of alternator failures, not bad diodes or bearings. On my Bosch alternator, you simply unscrew 2 screws on the back face and pull out/replace the brush assembly. Has anyone done this on the Nippondenso? With factory rebuilt alternators (the only thing that worked for me last time) - with rebuilt units costing > $300 this would be an economical way of refreshing your alternator giving many 1000s of miles/kms of worry free driving. Only problem is removing it from the Mk 1 is a !@&*(. I disconnected the exhaust system, but someone said you can carefully "snake" it up without having to do this - any one do this? Bill William L.

I left replacement of the rear tires go a bit too long and I was in desperate need of new rears (fronts needed replacement as well, but not as drastically as rears). I couldn't find the beloved RE71's in stock size. I had never ordered tires mail-order so I looked around locally (Columbia, SC) for performance tires and came up blank in the stock 14" size. I succumbed and put Dunlop A62's on all corners. They were the top rated performance tire by Consumer reports so I figured they couldn't be that bad. Boy, was I wrong. They were TERRIBLE compared to the RE71s! I knew that any new tire will not perform as well as a nicely worn tire due to tread squirm so I waited and waited, but it never got better. The story ends well however. This experience pushed me over the line and I finally decided to upgrade wheels. I replaced my stock 14" wheels with 16" Fittipaldi Polaris wheels and Yoko AVSi tires. I got the package from the Tire Rack. The car handles better than ever and the upgrade really improved the appearance. I got great service from the Tire Rack and will order from them in the future.

Though I go through them in about a year on my '91 (one of the first my dealer sold in May 90). I love the Bridgestone RE71 tires for my rear, in the stock size of 205/60R14, now only available in V rating. My local Firestone dealer wants $125 each for them, but through begging (anf I keep coming back for more) I get him to discount. But I digress. Seems that there is a national (USA) backlog of these tires, They are only made in Japan (I also called Bridgstone USA myself). Bridgstone says there isn't currently a production date in Japan, so I'll be waiting at least another six weeks on top of the eight I've been waiting. The dealer's put Firestone Firehawks on it, but the oversteer and high speed instability is deadly. With his "Platimum Guarantee", he'll be taking them off as soon as replacements appear, and in fact has agreed to put on any brand I can locate. Now the questions: What's anyone using in this size? What are the available tires for this car, and what are their characteristics? If I can get what seems like a comprehensive response, maybe I'll put together a FAQ. From my own knowledge, I've had Pirelli P600s on it. They handled almost as good as the RE71s, but lasted a little longer. I had Toyos on it, but they handled like the FireHawks. TIA, Ray Nicklas Tampa, Florida Check w/ the Tire Rack for those tires. I just checked their web page (www.tirerack.com) and found the following pricesl Bridgestone RE-71 205/60VR14 TOY $88 + shipping from Ind. or Utah depending on where you are, usually runs $6-$8 each, Still beats $125+tax each Regards, Bill ------------------------------ End of mr2-digest V1 #1583
