Most of the niggling things we lacked for last weekend have been done.. parachute mount made, etc. Barring any complications, we're talking about taking it to Virginia this weekend to run it in the 1/4 and then Reynolds the following weekend.

I will keep watching??? I want to know how it is going to run??

Which track in Virginia, and when? Richmond is only a 2 hour drive, hmm? :-)

[SGRIM]

Vmp!

[DonWG]

Excuse you.

Oh! Was that a car sound?

Nah, he was teasing me :-). VMP is Virginia Motorsports Park near Richmond, he just left out the when. Please post when you guys know for sure, and when - I feel like a short road trip since I couldn't get down to NC for the bash last weekend.

[SGRIM]

Okay, hopefully we will know friday morning...

[TURBO54]

Eric installing trans shield. brakes are bled, parachutes mounted one more #12 fitting for the fuel system, oiling system done and primed. looking to fire it up about lunch time tomorrow.

[kenny]

I know which webpage I'll be browsing bored at lunch tomorrow.

Hey Shane, VMP's web site says they are having a big truck racing event this weekend. Doesn't look like any cars will be running - is there another track you can hit?

I am going to be in Virgina, I would love to see the car let us Know!!

[JOHNDEEREGN]

Did she fire today?

[Top Speed]

Very, very nice! I can't wait to see it at Reynolds. Awesome video too!

No Randy is checking and rechecking everything over again. That is normal for him Plus we where rushing so much last week, they just want to make sure we didn't miss anything...

HOPEFULLY FIRE UP TODAY!

[mjdwyer23]

Updates? It's been more than 24 hours!

[TURBO54]

It runs now but Jay has the video camera, maybe he will bring the camera so i can post it.

[John Wilde]

The video is sick, worth the wait fo show!

[TURBO54]

First Start up!

[Robert Wilson]

Cool.... Its too quiet though.

[JOHNDEEREGN]

OH HELL YEAH!

[turbofabricator]

It looks and sounds GREAT guys. Good job, and Godspeed to ya!


You know......Godspeed....that's even faster than the Millenium Falcon! Maybe not as fast as SpaceballONE in "Spaceballs", though. (it goes "Ludacris speed") For those that haven't seen it: YouTube - Ludicrous speed, GO! Jay, you'll have to get one of those "Ludacris speed meters" for the car. Might come in handy.

[DonWG]

Great! Sounds like an alcohol engine. It'll sound better when some heat builds up in the engine.

Don't be stingy with the fuel at transition.

[DonWG]

One more tip. The alcohol makes a lot of water as a byproduct of combustion. If you're going to start the engine, make sure you reach operating temp before you shut it down for the night. On a cold start, water will collect in the cylinders. When you shut the engine down without enough heat in it, the water will sit around the rings and create rust rings in the cylinder. Nothing major, but you will see them when you tear the engine down if you let this happen. Speaking from experience. Don't just start the engine up for every Tom, Dick and Harry if you're not prepared to fully warm it up.

There's going to be a lot more to think about and take care of when running pure alcohol.

[six shooter]

I bet it smells great too!

THANKS GUYS!!!!!!!!!

Man talk about music to my ears


Did anyone notice the turbo's?

[kenny]

Awesome.

When do you guys plan to take it out for shakedowns?

Nice post BTW Don, THANKS!

[SGRIM]

The turbo's are spooling at idle, I LOVE IT!!!!

Hopefully this week.. we still have a little wiring to do and we need to make a wing for the car. Im hoping we can take it to the local 1/8th mile track later this week tho.

[DonWG]

No problem. Anything I can do to help, let me know. Fun time begins.

Can't wait, I check this thread like five times a day.

Our engine management system has some unique features that Im hoping makes tuning a little easier. Unlike most systems that work off of wideband, the KAM system works off of EGTs. Each cylinder has its own EGT probe and the computer monitors every cylinder and adjusts the fuel accordingly. You can set thresholds where the system will add a little fuel and recheck the temperature.. if its not enough, it will add a little more and if that's not enough, it will either cut fuel or spark or both to that one cylinder.

The KAM system does have wideband input and it does use it but the majority of the work is done with EGTs. It's a pretty nice system.

Sounds interesting. What target EGT are you using? 1150 to 1200 would be pretty safe to start out with (low boost). 1050 to 1100 for high boost. I wouldn't ignore the O2 until you find out how responsive the EGT system is. I would imagine the O2 system would react faster than the EGT. The supplier of the EGT system should be able to give you a time delay figure. Don't rely totally on the O2 though, especially when you start moving up in the boost and a/f richness. You may be needing to run a/fs without an intercooler that an O2 will not read accurately or at all. Around .7 lambda or most likely lower (.65) without an intercooler. Some supercharged, non-intercooled engines have to run as much as 3.0:1 (.47 lambda).
