Team Woodfin's Bantam Roadster Build
 

Team Woodfin is busy with drag racing.

We have a friend who says. "anything worth doing is worth doing to excess" We are following his advice!

We have another thread underway about "Dad's" GT Super 10. This thread is the build up of my Son, Jeff Woodfin's advanced ET/ Top Dragster/ Fast Brackets Bantam Adtered.

Complete details soon.

Re: Team Woodfin's Bantam Roadster build
 

Bad to the bone Kevin Self 11 degree heads and matching intake. The engine will be a 420 SBC of about 920 horse.

Re: Team Woodfin's Bantam Roadster build
 

Heads and intake are setting on plastic BBC - the alignment is slightly off :) Only one hole would align so a clamp kept it from falling off long enough to snap the photo.

My Son Jeff is just under the camera ready to catch any falling parts.

Re:Team Woodfin's Bantam Roadster build
 

15 months later we have the altered in our possession!

This buildup begins right away with some items of interest as we progress;

* Equipped with dual throttle bodies Holley EFI

* Holley digital dash

* Brodix aluminum block, small block, raised deck, raised cam 60 MM cam journals, 417 CI

* Kevin Self custom Brodix cylinder heads

* Kevin Self custom EFI intake

* plus a number of other interesting item, stay tuned, photos and story line soon.

a teaser with "Ellie"

Re: Team Woodfin's Bantam Roadster Build
 

Iam a big fan of altered's,my first real race car was a 23T.
Look forwards to the pics and rest of your build.
Best of luck to you.

Thursday evening updates:

Jeff's Daughter and Son, all in the Family :)

Re: Team Woodfin's Bantam Roadster Build
 

some details of details

Re: Team Woodfin's Bantam Roadster Build
 

We are charting new ground [for me] with the usage of a Holley EFI system. The system has two throttle bodies, eight ignition coils, eight injectors, all the normal sensors, data recorder, and electronic dash display.

For me, the EFI lessons are welcome and I will document the learning.

With this buildup the EFI is the star. While the chassis, drive train, body and paint will all be outstanding, show casing the Holley EFI will be the main attraction.

Re: Team Woodfin's Bantam Roadster Build
 

While Monte worked with the Super 10 block I kept busy with the Roadster's rocker arm set up and pushrod length checking.

*Note the intake lifter and rocker offset

*Note the cylinder head height. The head is a Brodix 11 degree casting worked by Kevin Self. As I began checking the pushrod length I quickly realized this head is not a typical small block head, it is very tall. To establish the proper pushrod length required using a BBC exhaust length checking pushrod!

Re: Team Woodfin's Bantam Roadster Build
 

#227 shows what can be considered "big lift"

#229 shows the 60 MM cam journal. Monte says it looks like the engine has two crankshafts

#230 shows the cam at 113* per the cam card

#231 cam at 113* and intake valve a full "big lift" :)

Re: Team Woodfin's Bantam Roadster Build
 

so you can see part of the vision

Re: Team Woodfin's Bantam Roadster Build
 

I like beautiful and shinny parts. Check this outstanding work by Dan Olson oil pans.

Re: Team Woodfin's Bantam Roadster Build
 

A good work day - planning day for the Roadster

Re: Team Woodfin's Bantam Roadster Build
 

At Woodfin Automotive we work on EFI equipped cars and truck most every day. Yet, we do not race those cars ! Nor do we engineer the systems, we simply repair them.

Our roadster is not only a new exercise in drag racing with EFI it also requires some home spun engineering.

In keeping with the basic theme of hot rodding if you are not modifying or customizing every part on the package you are being remiss.

The engine is a Brodix aluminum block with raised cam and raised deck. EVERYTHING that bolts on the block requires some tweaking.

Here I am spotting the magnet bolt that will screw into the cam gear. The magnet is set at 195 degrees before TDC #1 firing. It identifies the #1 cylinder position for the ECM and begins the injector firing sequence.

Re: Team Woodfin's Bantam Roadster Build
 

the cam sync sensor tucked behind the water pump

bolt with magnet in head for sensor signal

Re: Team Woodfin's Bantam Roadster Build
 

Q - What is required if the fenders need to be wider? If you want the tire tread under the fender?

A - Modification! Simply cut off them off, splice the width, reinstall. No hill for a hot rodder :) More specifically, our team member body man extraordinaire,Joel.

Re: Team Woodfin's Bantam Roadster Build
 

Q - How many ignition coils does an Holley Dominator EFI system need?

A - All of them!

Re: Team Woodfin's Bantam Roadster Build
 

Coming along good ! How son you think it will be on track testing ?

Re: Team Woodfin's Bantam Roadster Build
 

Jake, first runs are some months away. many details yet to attend :)

plumbing and hardware details

Re: Team Woodfin's Bantam Roadster Build
 

In the case where you do not like the fender fit, you cut the fenders off and move them!

Re: Team Woodfin's Bantam Roadster Build
 

Just wondering why such a big tire 10.5x33-16 is a very good tire? Love the build just asking about the tire!

Re: Team Woodfin's Bantam Roadster Build
 

Blind,

about the tires, we made the decision based on feedback from M/T and other racers.

Re: Team Woodfin's Bantam Roadster Build
 

MULE,

I'll expound a little further on our tire decision. We race in TX and the tracks we frequent can get marginal in the summer months. I was considering the 10.5 tire, but elected the larger footprint of the 13.5.

Early estimates on ET are in the 4.50 1/8 mile 6.90 1/4 mile range and having a little more tire doesn't upset me.

We appreciate the feedback and look forward to sharing more details of this build.

Re: Team Woodfin's Bantam Roadster Build
 

Jeff only has about $9,000.00 plus in these heads so take a hand drill and just poke a hole right through them:)

Re: Team Woodfin's Bantam Roadster Build
 

That would open a water passage?? Connect to...??? For the purpose of...???

This is no SS or bracket Mustang, is it?

Dale

Re: Team Woodfin's Bantam Roadster Build
 

Fire,

you are correct!

Re: Team Woodfin's Bantam Roadster Build
 

Dale,

the drilling and threading is as you suspected, you will notice the water lines coming off each side of the water pump going into each head. This pumps extra cooling water around the two center exhaust valves.

It is a suggested modification that I think is a good idea.

And you are correct about this is not your average package. Keep watching, you ain't seen nothing yet :)

Re: Team Woodfin's Bantam Roadster Build
 

Guys this build is a joy to follow along with. Great work!
Jeff,totally agree with your tire size choice.
When we ran quick 8 dragster,we had 12' tires for good hitting tracks
and 15's for garbage tracks. Not only where the 15's necessary for
marginal tracks,it helped the "ride" down track.

Re: Team Woodfin's Bantam Roadster Build
 

consider experimenting with the "Cobra Head" ties. The design allows the cut off tail to lay flat against the wrapped section.

plumbing progress photos

Re: Team Woodfin's Bantam Roadster Build
 

After a short slow down the building action is amping back up.

Coming soon is the electrical component mounting and wiring runs.

This new item just in from Kevin Rodden [K & R Performance] showing his usual beautiful work.

Introducing his new Pro-Cube with dial-in display! The two small connectors use fiber optic cable to send the display data. Way cool

Re: Team Woodfin's Bantam Roadster Build
 

Hot Rodding requires building one of a kind brackets, or in this case, two of a kind.

The roadster cockpit is tight or like Monte says, "real estate is limited"

This is plan "D" for mounting the Holley EFI/data logger display, plus K & R switch panel, plus a panel for other controls.

Re: Team Woodfin's Bantam Roadster Build
 

This is our first time to utilize a 100 % duty cycle solenoid as the master cut-off control. While I initially had some reservations in talking with others who have this setup the feedback is good.

So, we'll give it a go.

Re: Team Woodfin's Bantam Roadster Build
 

Jeff had two good days of progress with roughing in wiring and working on other areas. Fuel plumbing and intake manifold completion are next.

Re: Team Woodfin's Bantam Roadster Build
 

Team Woodfin:
Really enjoying reading about your build. These forums can be such a great learning tool! You see things behind the scenes that you may not notice once the build is complete. Looking forward to hanging out with you guys and watching it go down the track.


ps - for those who don't know the Woodfins personally I can tell you they are both a class act!

Re: Team Woodfin's Bantam Roadster Build
 

Because of the tall deck block and sheet metal intake the manifold end rail gap is wider than usual. To correct that two 1/2" thick Delrin spacers are dowel pinned to the block. Now only a .035" gap requires sealing with RTV.

We have the body back on to check fit in several areas, one area being the dash panel.
Once the templet is satisfied a panel of carbon fiber will take it's place.

Also, race cars with EFI require extra wires :)

Re: Team Woodfin's Bantam Roadster Build
 

a few update photos. Everything is still in the pattern, rough in stage yet we are making progress.
