Thanks for the tip Greg. Just ordered one!

Andrew

Car looks great as always.

Is it me or is that a huge filter :poke:

Always so impressive and setting the bar higher and higher. Thanks!

No hurry:poke:

1000+hp needs a lot of air.

Good luck making the show, guys!

Des Moines
 

We made it to Des Moines. It was a huge thrash but we made it. My Dad picked up my new Finspeeds Thursday and we installed them Thursday night.

It was fun to see all the cars togther.

Which one is your favorite?

This is a great shot Mark...

Any chance of the group getting back together anywhere else this summer?

YES, it WAS cool to see them all together!
 

Not only was it cool to see all of them together, but it was GREAT to meet you in person!

I enjoyed seeing the White one more than I anticipated because frankly, I read those articles back then and because it presents a much more attainable goal for me and my Camaro, and it likely exceeds my needs and driving ability to be quite honest.

I want to thank you again for signing my book, that conversation felt a little awkward on my end... but kidding around as you prepped Hellfire Saturday in the Auto-X area is a great memory for us. Thank you!

Kurt and Andrew Chenoweth gave Jodi and I our first Auto-X rides ever in their 70 Challenger Fasturn and although the view is very different from the passenger seat with zero control, I cannot see myself pushing my Camaro near that far any too soon... but I am Sooooo looking forward to it!

I think this was a one time deal. Getting the cars togther is tough. It worked in Des Moines because two of the car are in a collection there now.

Hot Rod is doing a feature on the cars so look for that this fall.

Mark

Last winter you mentioned something about a possible reunion in NKC, was hoping to see that happen so close to home. Heck, I'd like to see just one of the cars in person...

Still loving the seats BTW, thanks again.

The best compliment a Man can receive!

(sorry just read more, not copying Sieg, I miss my Dad, he sounds allot like yours)


Thanks for all that you share, it is inspiring.

You gotta stand back and look at them and say to yourself, I'm a bad man!!

A picture speaks a thousand words and all of those cars represent why we love to do what we do.

Well done Mark and all the people who helped you in the creation of such an amazing vehicles.

Amazing collection of cars right there, and every one a step forward in performance.

Beautiful craftsmanship.

Congrats on making the show, Mark!

I'm considering those Finspeeds for my '69 but that's still at least a year out.

They look great and the whole car looks amazing.

Great job Mark.

Update
 

Sorry it has been a few month since I posted a JA 2.0 update.

This project has had a few more sorting out issue than most of my last projects. I think it was due to some old parts and some new and everyone including myself has gotten much busier.

So we finally have it up and running and running well.

The engine layout worked out great and the extra intercooler spacer gives the engine a little differnt look.

http://i439.photobucket.com/albums/q...psveuqslgx.jpg


One issue we chased for a bit was a fuel delivery issue. On the chassis dyno it would drop fuel pressure. With the help of Carl Casanova at VaporWorx we sorted it out. I need to flow 2.3 gallons a min at 60 psi to support my power levels on E85. With 2 CTS-V pumps and a boost a pump we can do it. The car is putting down well good solid numbers now. Before everybody gets all what kind of power does it make--- Let me say I think chassis dyno numbers are a bit of BS. I just wanted to verify the fuel system and the calibration without going to jail. I was doing 3rd and 4th gear WOT on the hiway and it was getting a bit sketchy.

I've got about 1400 miles on the car now and it runs strong. The E85 has been a fun experiment. I have a station 4 miles from my house that has it. It is cheap but I go through it fairly quickly.

Matt at Sled Ally made a cup holder / phone holder / Lat Long Sensor cover for the car.

We also added Gen 2 mirrors so I can have mirrors on both sides of the car. Much easier to drive.

Mark what is your feeling on how the temps are working out? Its very interesting esp with JA's new cooler package and the swap to the bigger bricks (and cooler running E85).

Glad to hear you guys have made good progress with the car, Mark. Enjoy it before it gets too cold.

I'll be at the track Monday on a 90 F degree day so it will show one way or the other. So far on the street it has been great.

Mark

I love this car and this is my favorite part of the car and now I want one and don't feel bad we have spent the last year trying to sort out the issue's with my very basic motor and I think we have finally figured it.

What benefit does the BAP give you on those pumps? Was pressure does it push it to? I was told the CTS-V pump has a bypass that opens at 65psi. I'm likely going to be looking at ways to push more pressure from if possible.

My issue will be differential pressure across the injector affecting how the injector reacts (with boost).

Appreciate your help. Love this build and glad you got to do some experimenting on E85. I hope to do some myself in the future.

William

Will

You are correct a CTS-V pump does hit the internal pressure relief at around 65 psi. These pump are sensitive to voltage. At 60 psi the pump will flow 482 lbs per hour at 13.5 volts and 615 lb per hour at 15.7 volts. With my system running at 13.5 volts I would be right on the edge for fuel flow. I need about 850 lbs per hour. So with a 20% safety factor I need about 1000 lbs per hour of fuel flow for E-85 to support 1150 HP piston HP. I'm right at 1000 HP at the flywheel and need 150 HP to turn the blower.

I built a test rig (Stop watch and a bucket) to verify I have sufficient fuel flow as installed in the car. I could not maintain 60 psi and the flow rate I needed without the boost a pump. I ended up with two Vapor Worx models and one boost a pump because a boost a pump can't handle more than 30 amps. Both pumps pull 44 amps so I'm just boosting the voltage on the 2nd pump. I stage the pumps with a Hopps switch. Once it hits boost the 2nd pump with the boost a pump kicks in. With two Vapor Worxs system the fuel pressure stays rock solid at 60 psi all the time.

On a side note we integrated a GM truck E-85 sensor so the E67 controller reads the alcohol content off the sensor and adjusts the pulse width and timing accordingly. Our pump E-85 in MI is not always 85% alcohol and if a gas station does not have E-85 I can run 91 - 93 octane.

Because I read the CAN data I can display the alcohol content on my dash. I know all of this is geeky engineer stuff but it is cool.

The car pulls hard on E-85 and I see no spark knock activity. On 93 pump fuel I can see small traces of knock that we pull timing for.

It takes a bit of getting use to the smell of the E-85. It is different not bad just different. So far it has been a very fun experiment and I'm looking forward to taking it to the track. Also the $2.10 a gallon is kind of cool also for E-85.

Mark

Factory look under the hood...priceless.

And kudos also Mark on upstaging #Deflategate



:thankyou:

that right there is above and beyond stuff. Nice work Mark.:thumbsup:

I appreciate the lengthy response and can also appreciate the nerdy engineering stuff as well.

I have virtually the same tank you do with dual V pumps and may have to look into the BAP mod for mine. Reading this I'm slightly worried E85 may be out of the question for me as i'm expecting to be in the 1000rwhp range on pump gas (93). Not sure those pumps will be able to be pushed enough to safely support the additional power E85 will make.

I like the idea of integrating the E-85 sensor, makes it easy to play it safe with the inconsistencies of E-85 from the pump!

Maybe I can work out two BAP setup on mine to see if I can get both to push at 15.7V when required. Then the issue becomes the effectiveness of an injector when instead of 60psi differential, you're looking at it's flow on a 45-48psi differential.

What injectors are you running on this car for 1000flywheel?

William

I have Injector Dynamics 155 lb/hr injectors. They seem to work fine.

Sorry it seems like I'm playing 20 questions.

What ID is a 155 lb/hr? I have the ID1300 and contemplating going to ID1700s.

Kids...Don't try this at home.....

I can't even run a GoPro...

Also maybe I missed it but does your vaporworx setup have a return line or is it deadhead at the rail?

I'd like to know if that is a one off piece from Sled Alley or is that someone a working man can get. Desperate need of that kind of option.

lol

#truth


:P

It is a dead head set up. The best thing about it which should not be over looked, is at idle and cruising around the CTS-V pump is just low load like a stock car. Hellfire has a similar system and Charley drove it on Power Tour with zero issues. When you have high fuel demands the system ramps up and sends increased voltage to the pump to handle the higher fuel flow. At low load the pump is only at around 8 volts.

Carl's Vapor Worx system allows the use of OE style pumps (Durable and Validated) in our Hot Rods. Charely and Jody can tell all the stories of other fuel systems they tried for Power Tour. Ice bags in the trunk and the Mule also had a fuel to air fuel cooler. The new stuff is way better.

My new system is a true flex fuel set up. I can run 91 octane, E-85 or race fuel. I wanted to do this for the latent heat of vaporization that the E-85 gives for blower engines and it is cheap. At most track days I run VP109 and that is now about $8 a gallon. With E-85 at $2.10 a gallon burning 30% is a no brainer. It has been a little bit of a science project and I want to get it to the track and see how it works.

Mark

Fully agree on all points. That's why I did vaporworx and OE pumps (cts-v). Having heard from friends the horror stories of vapor lock and icing gas tanks. The technology tested by manufacturers is FAR beyond what the aftermarket does.

Made it a simple decision!

Looking forward to your updates on e85 track day.

Thanks,
William

Mark,
J/A is all steel, (except the hood, right?) while Hellfire has C/F fenders, inners, trunk lid, & bumpers. Yet the rest of the cars are pretty similar.
Have you weighed them both to see the weight difference?

Thanks for the continued updates. Very interesting to follow!


Bill

Bill

Hellfire is about 125 lbs lighter and mostly off the front. Hellfire also has 315 tires on the front and the splitter and slightly larger rear spoiler.

That is the biggest mechanical difference between the two cars. On similar tracks Hellfire should be faster than JA.

Mark

Mark, any data on the new bricks?
