C Allen ------------------------------ From: uunet!netcom.com!ssr (David Kucharczyk) Date: Tue, 18 Jun 1996 14:07:58 -0700 (PDT) Subject: SC pully info Someone asked about the oversized SC pully. I recently installed one on a completly stock car and did numerous measurements. Here's the data; Size - stock pully 5.120" alternator belt, 5.710" SC belt. - HKS 5.120" alternator belt, 6.110" SC belt. SC belt diameter increased by about 10 mm. The pully also acts as a harmonic balancer, and has a hard rubber strip that lives between the outer part of the pully and the inner part (it's actually two concentric pieces with rubber between them) and is dynamically balanced (look for the drill holes on the back side of the pully) just like the factory unit. This explains the $300+ price for the HKS pully. Boost increases by 1 to 2 PSI depending on RPM and engine load. You need to connect the Air Bypass Valve vacuum line directly to the intake manifold instead of the controller solenoid (VSV in Toyota speak) to run the boost much higher than 8 PSI. Installation is very easy. Jack up the car and remove the pully side rear tire. Put the car in 5th gear and put on the parking brake. Loosen the belts. You may need a low profile ratchet/socket to get at the belt adjuster lock nuts as there isn't much clearance between the body and the nuts. If you can't get at the bottom nut (the SC belt adjuster) letting the car back down onto it's tires may cause the engine to move down a bit and give you the needed clearance. Use a breaker bar or impact wrench to remove the pully bolt. Wiggle off the pully and install the new one. Tighten the belts. If you hear a high pitched squeal or hissing sound when you rev the car and see a drop in boost your belts are slipping. Use a belt tension gauge to check the belts if possible. I'll be putting a more comprehensive article on the 4AGZE SC system on the web page shortly. dave ------------------------------ From: "Miceli, Fred (Contractor)" Date: Tue, 18 Jun 1996 07:29:36 -0400 Subject: Re: 3M Car Care Products Sanjay Patel: Where did you find the 3M waxes, etc??

Hey there from Florida! My name is Christopher Long, and I'm new to the list. I saw Dirk's posting, requesting info on what various aftermarker products do, so I' thought I'd attempt to provide something before I pick the group's brains about a little problem I have. :-) My car is a 1993 Turbo with most, if not all of the options. I purchased it used in late '94, and the previous owner had already added what I believe is a stage 4 package from HKS: Super Powerflow, EVC, FDC, VPC, exaust, boost gauge, and turbo upgrade. I'll attempt to explain what these things do. If I make an error, please correct me. The Super Powerflow is a less-restrictive replacement for the stock air filter. It is not a drop-in replacement like some others, because you must remove the old air filter housing. EVC: Electronic Valve Controller. This is an integral wastegate for the turbocharger. Let me first explain what the stock wastegate is/does. The stock wastegate is basically a valve that lets out excess boost pressure. The stock wastegate is set to open somewhere around 9-11 psi (not sure exactly). The EVC package includes a 2nd wastegate which you will put between the stock wastegate and the turbo. The EVC will then electronically monitor the boost level and use its own wastegate to bleed off pressure so that the stock wastegate opens only when the EVC wants it to. By using the EVC, you can increase the boost pressure that the turbo generates. But unlike putting a simple twist-valve (like the Greddy TWWC) in there, you can turn off the EVC from the cockpit with the push of a button, and the car will now operate like stock. FCD: Fuel Cut Defenser. The turbo's wastegate is a safeguard against overboosting. But in case that fails, the MR2 turbo has a fallback safeguard: The computer cuts your fuel if the boost pressure gets too high. I'm not exactly sure where it cuts it, but I think that it's somewhere around 10 or 11 psi. You can't run high boost if the computer cuts your fuel. The FDC is a small electronic gizmo that you hook into the wires going into the car's computer (located against the firewall, in the trunk, left, behind carpet). It will override the fuel-cut algorithm. I'm not exactly sure how...I guess it alters some signal either sent-into or sent-out of the computer, making something think "it's not time to cut the fuel yet." You need an FCD to take full advantage of an EVC. VPC: Vein Pressure Converter. This replaces the stock air-flow meter (that aluminum thing that your stock air filter box is attached to). The air-flow meter is restrictive and offers no options for reprogramming...should you decide to make changes like bigger fuel injectors and/or a bigger turbo. The VPC has its own boost sensor and air temperature sensor...plugged into its own controller that has its own fuel map. All of this information is then fed to the car's computer. According to the HKS catalog, you don't need a FCD if you have a VPC. (Interesting...mine is still hooked up....) All of this stuff is used to make the car "breathe" better. As a general rule: more air plus more gas equals more horsepower. However, there are limits: More air plus not enough gas equals blown engine. (Yes, I speak from experience.) That is why the turbo has a wastegate and the computer has a fuel-cut algorithm. Your limit will be around 17psi. I don't think you can exceed that without some upgrading of the fuel system. Hope this helps.

Hello Everyone, Since I did not see any coverage whatsoever of the 24 hours of Le Mans, I did a Yahoo search and found the official Web site. In it I found a picture of the Sard MC8R car, which someone has reported as being an MR2 with a turbocharged Lexus V8. The nose is heavily modified (I guess due to the need for better cooling), and it has a racing wing, but you can definitely see the car's MR2. This baby was driven by Alain Ferte and Pascal Fabre, both French, and finished 24th overall this year. The address is: http://www.24h-le-mans.com/fr/epreuve/index.html Then follow the links for 'voitures', 'no 46'. There are other interesting pictures and Quicktime movies in this site: McLaren F1s, NSXs, Ferrari F40s, Porsche GT1s, Vipers. If you need help with French, I can read some.

Sitting on my doorstep was a long paper cylinder - the kind that are used to hold posters. It was even sent via 2-day mail, but had Toyota Motor Co as the return address. Inside I found a big poster of the Toyota IMSA racing cars (GPT I believe it is) - nice, though I would have rather had a poster with a MR2 on it... :) I also found an envelope stuffed inside, which contained a letter, and a box with a Toyota-logo keychain in it. Sort of a random gift-pak of stiff courtesy of the MR2 owner's Club. Now to the interesting part. Here's what the letter says: > >Dear MR2 Owner Club Member: > >Just a brief update on what's happening with the Club. > >Unfortunately, we have been forced to cancel the Atlanta to Gatlinburg Road >Rally due to lack of participation.

Matt Murray ------------------------------ From: Jodi Elder Date: Tue, 18 Jun 1996 19:30:02 -0700 Subject: Boost Mods Hi there Brad, I also recently installed an MR2 Performance Products manual boost controller. The following summarises my car's set-up and my results: I have: K & N FIPK Straight pipe after 2nd Cat. Ignition is standard. I was able to get about 2 1/8th turn before fuel cut which is probably around 11.5-12 psi. The stock gauge pegs out just above the + sign. The additional power was fairly obvious and turbo response was improved a little. My gut feeling is that the engine now produces around 250 hp. So, the gains are noticeable and the car is a lot of fun to floor between corners..faster spool up and better acceleration. But, I think I will still get an FCD (or actually, a GReddy Boost Cut Controller). I'm greedy and want those extra 3 psi. I know what you mean, Brad, the increases don't leave you breathless but they certainly are there. You might note that I noticed significant improvement with the straight pipe and K & N filter before I even installed the boost controller...more responsive. I think this combination probably provides a much better overall improvement than just the boost controller alone. I think this is a great unit and with the FCD should be all most people need...for now anyway.

One nice thing about Michigan... we don't have those silly front plates. I hate them! When I lived in Ohio I traditionally refused to install the front plate and never got stopped. Lucky I guess because several of my friends did get stopped by police and were nicely asked to install it.
