I'll have to dig up a couple of mine and get them up on the interweb.
Think I have some from Road ATL, Roebling and VIR somewhere.
I know on the f and s enterprises web site if you look at the photo galeries for trackdaze and mazda drivers events you can find them. I'm thinking about getting a few of those eventually.

I do have a few questions about your car at VIR. I am the one who is taking his 96 LT-4 to VIR in Oct. How fast was your car on the back stretch before the modifications, or did you drive it there in that conditon. I road with an instructor in a M3 BMW doing 150 on the back stretch. It was supercharged. My brothers Mustang would do 120.
I thought, I saw traditional round air cleaner in one of the pictures. Did you switch to a carb?
Last question for now, what suspension changes did you make?
Thanks!

- I never drove the car stock so I have no idea what a stock C4 would do.
- Yes, the car is a carbureted 383ci LT4.
- The suspension is all stock mounting points but the only stock parts left are the A arms. The shocks are custom valved Bilsteins and every other piece is done by Vette Brakes.
As far as top speed goes. When I answered before I should have said that I really don't know for sure what I am topping out at. I don't have a speedometer in the car. I have had a Garmin GPS in the car that showed a max of 153 but it is delayed pretty bad so I am guessing it is close, but just a little low.

2. I'm pretty sure the kid in the Miata was just looking for the door that got blown off when the white and blue GT2 ACR Viper on the right side of the picture went past.

Red, what is that sensor thingy that appears to be connected to the red crank pulley on the front of your engine? Looks like an 02 sensor, but that can't be...
Also, there's no Opti, but a conventional distributor. Interesting.

Suspension - new poly bushings, re-valved bilstien FX3 shocks.
Engine - headers and exhaust.
Brakes - J55 with carbotech xp12/10 combo
Not pushing it I can get to 110 by the flag stand on the back straight, since I've only run there on HPDE days (not trying to break anything) I don't get much faster. At Roebling Road and Road Atl I've seen 125+ on the straights. Bigger question at VIR is what speed do you enter the uphill esses and what do you exit with? I'm still chasing some suspension gremlins and 110 is about all I can handle at the exit of the esses.

For those who might not know crank trigger ignitions, this is straight from wiki. (Of course if it is on wikipedia it's true.)
A crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.
The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing. It is also commonly the primary source for the measurement of engine speed in revolutions per minute.
Crank sensors in engines usually consist of magnets and an inductive coil, or they may be based on magnetically triggered Hall effect semiconductor devices. Common mounting locations include the main crank pulley, the flywheel, and occasionally on the crankshaft itself. This sensor is the most important sensor in modern day engines. When it fails, there is a small chance the engine will start (engine will likely cut out after a few minutes of driving) but it mostly will not start.[citation needed]
Some engines, such as GM's Premium V family, use crank position sensors which read a reluctor ring integral to the harmonic balancer. This is a much more accurate method of determining the position of the crankshaft, and allows the computer to determine within a few degrees the exact position of the crankshaft (and thereby all connected components) at any given time.

I have a 92 LT1 and maybe I can help since mine is pretty much stock.

I have to go now to ebay and look for some racing seat belts.

Start another thread in Autocross and Road Racing session and you will get TONS of input.
Unless you have a race seat and roll bar don't worry about the race harnesses.
