Camaro XV

[nicks67ca]

I was able to get in early and check the car out with almost no crowd in the show. I spent a half hour just looking the car over. Mark was even nice enough to say hi and ask me if I had any questions about the car

Some more impressions of the car
- The Jake Skull on the shifter and rear window are nice touch.
- The car is clean its hard to see all the technology in the car. The hoses, wiring, connectors, are all well hidden.
- The Z28 influence is evident in the front splitter, and rear wing.
- The underside components are invisible they are tucked so high up.

I could have looked at it all day!

Mark,

I really enjoyed reading your feedback on how Hellfire has been performing each step of the way to OPTIMA. I know last week had to be very hectic and you are probably still trying to get your feet back on the ground. When you have an opportunity, can you give those of us that were foolish enough not to go to SEMA your thoughts on the car's performance?

Mark,

My favorite part of the day Saturday was when I was watching you make a pass on the Autocross. When you finished your run and idled by, a nice gentleman next to me nudged me and said "That's my son". I said "You are Mark's Dad? You must be very proud. He's an engineer's engineer and one heck of a nice guy who doesn't let all of his success go to his head."

As a proud father myself, I could see how proud he was in his eyes and maybe even a little emotional crackle in his voice.

That was a very cool moment.

Don is an absolute gentleman and it was a true honor to meet and converse with with him during the week.

Could Mikels or Mark explain why the car has so much un-burnt fuel coming out the exhaust and creating this "hellfire"

I'm not completely familiar with LS engines yet and what and how the computer regulates things, but I'm trying to pick things up.

Generally with an old school carb on a race engine, when you are shooting flames out of the exhaust that's not exactly a good thing. Obviously it's loading up and the carb is running rich, so depending on air temperature etc.. You would change jets in the carb.

I'm just interested to know what's going on here. I looks badass I know that much. I laughed like crazy when I saw a photo of hellfire really flamed up and people were commenting thinking Mark blew it up. Now that was funny.

I'm sure it only happens on decelaration !

Its common on RPM-MAP based ecus in race applications for the lowest MAP bins to be set at the max vacuum that you can pull while opening the throttle quickly. When you quickly close the throttle quickly at high-load, high-rpm, you can often get the MAP to dip below that value and it will cause a rich condition that produces popping and flames. You can tune it out by spreading out your MAP bins, but it will lower the resolution of your fuel tables in the normal operating range and hence isn't usually done in race applications.

Mark, I am curious if you think you may revisit this thought for 2015 and/or beyond.
