Paul, I know the feeling. My next project is a street legal race car (or as close to it as I can get). I want to drive the track only car now, but It's not legal, and draws just a little attention. Are you and Ron going to the convention in Daytona this year? Sounds like a tax write-off to me

Looks great!

Great to hear you figured it out. What plugs/gap are you running? The MSA show is on, a friend who is a vendor got a call from them asking if he was coming.

Paul, Why are you selling it?

What color is the smoke?

Yes, grounding is very important, so don't skimp on ground wires. There is no need to run shielded cable for fuel pump power. In electronic systems, power leads to high power devices are not shielded (like a pump or motor). Very low amplitude signals are. That is why the VR sensor cable is shielded. For you guys running ZXT distrubutors, it is also a good idead to shield the signal wire from the distributor to the MS even though it is a +12v square wave. Nissan shielded it. The idea of the shield is to keep noise from effecting low amplitude signals, not to keep noise inside the power lead of a high power device. It cheaper and easier to do it that way too (easier to shield little wires, than big ones).

In fuel injected road race applications, the surge tank is there to prevent fuel pump cavitation under hard cornering G forces. Like Tony said, the taller surge tank the better. This minimizes standing fuel waves in the tank. The wider the tank, the bigger the wave, which makes bigger troughs. The troughs will cause pump starvation. I designed a fuel cell that sits in the spare tire well of a 240Z. It has a surge tank built in. It has been working great for 3 years of road racing. It is applicable to both EFI and carburated setups. Yes, you must use a steel expansion tank (unless you are good at plastic welding ). Hear is a schematic for using the expansion tank as a surge tank.

What years? Thanks,

Anyone figure out exactly what year 200SX turbos came with the 4.11:1 R200s? Did the V4 200SX come with the 4.11:1 R200?

Hear are some photos of a 240Z I time trial race. It is still in a partial state of disassembly for winter upgrades. Note the signature, it sure makes it go faster

Just cranking the engine can cause noise. Noise from the starter motor can couple into a very low amplitude signal like the VR output.

If there is enough noise on the VR signal, then the EDIS module will not fire the coil. The VR signal has a very low amplitude, so any noise that couples into it can have a big effect. Where you you have the power to the MS connected? It should be at the battery (not the starter for example).

I like the MAS flares when molded in. Got a set waiting for my next project.

I pulled my 78' L28 apart that had close 190k on it, and there was no measurable cylinder wear.

Just use the reinforced silicon hose. The cheap stuff with no fabric reinforment will flatten out like a drinking straw, and will not withstand any boost. I remember on a local club road rally a fellow member with a Z32 made it about 5 miles into the rally. All of his trick silicone hoses had flattened out once they warmed up a bit. He had to limp to the local parts store to replace it all. I'm a big fan of black hose, it looks great even when dirty!

I'm perplexed. No, the damper is not required.

I guess it all depends on how you define hot. On a road course, the tires will get so much hotter than they ever will during a 60 sec autocross. I've run Hoosiers in an autocross, and they never really got as sticky as they do on a road course. Where shaven V700s or RA-1s got a lot stickier in less time. Maybe the Hoosiers were old, or the wrong compound, but they were no where near as sticky. Just my limited autocross experience...

Dragonfly, looks nice. I like the uncluttered look. Also like the shift boot Doesn't your leg get hot? On my road racer my driving shoe melted to the tranny tunnel after a 30 minute session. I've since put that aluminum faced 1/2" fiberglass firewall insulation on the tunnel. I'll post some pics.

Yes the shield is important. It should be tied to pin 7 at the EDIS module only. Do not connect it to chassis ground.

I'm running the 245-45ZR16s on 16x8 rims, with a 5" backspace. No rubbing up front, but I had to trim the fender lip in the rear to prevent rubbing. I'm not sure why anyone would want to run full on road race tire like a Hoosier slick for Auto-X, they will never come up to temperature to make them even slightly sticky in an Auto-X.

Are Toyo RA-1s legal in FP? I run 245-45ZR16s on 16x8 rims. Hear is what they look like: Miatas typically kick my but at Auto-x running 205 width tires.

Try swapping the VR sensor leads. If they are wired opposite, nothing will work.

I agree with Jon, either start stripping the car you have, or find another one that you can dedicate to race only. I got to that point with my turbo 240Z where I was doing 8-10 time trial events a year with it, and it was really taking its toll. I decided to build a track-only car, primarily so I didn't have to worry about getting it home after each event (trailer). It's the supercharged BRE schemed car in my sig. It's looks great from 25 feet or so, but up close, it is a little scarey.
