Slowly it starts looking like a car. :D

This is how the rear end of the car looks like from the bottom.

During the working hours the 289 is stored on top of the pallet rack - it actually occupies only one space.
I'm very fortunate to have a work place like that. Hard work and dedication will be rewarded, I can testify to that.

Thank you Bob (Boss).

Amazing work:3DSMILE:! Very nice.

Did you make the tank?

G-Pete 10-11-2011 07:28 AM

Got this one off Ebay, for $102 shipped. By the time I buy the AN6 fittings, the roll over valve and the aluminum - it would be around $50, it did not make much sense to me.

Thank you.

For the guys and gals who are interested in the steps to make this adapter for the steering wheel here my picture website

Steering continued.
Upper knuckle welded to the 3/4" shaft.

http://photos.imageevent.com/germanp...m_DSC06539.jpg

Lower knuckle welded, also to see here the FF5 adapter for the 99-04 PS Rack. If you buy DD/0.75" round knuckles and just round rod you save close to $100. The DD/DD knuckles and DD-shafts are that much more.

Shallow angles makes the steering smooth. I do not understand why other builders put manual steering racks and wide tires on their cars. It is just a pain to drive.
Besides that my wife can enjoy the heck out of it...

Lower radiator mount.

The radiator sits on a rubber cushion on the bottom.

http://photos.imageevent.com/germanp...m_DSC06547.jpg

The original radiator brackets were modified and used.

Plenty room for the supercharger intercooler.

G-Pete 10-23-2011 05:06 PM

My wife stepped by and took me to lunch, not before to try the pilots seat.

Bracket for the parking brake - the cup is from the donor.

Welded in place.

The brake assembly.

Bottom view of the adjustable bracket. I used the stock length of the cables.

G-Pete 10-23-2011 05:16 PM

Snatched a Harrison expansion tank on Ebay.

http://photos.imageevent.com/germanp...m_DSC06571.jpg

A little time and elbow grease...bracket is also done and polished.

http://photos.imageevent.com/germanp...m_DSC06574.jpg

One flange welded to the header and the second bolted on.

http://photos.imageevent.com/germanp...m_DSC06576.jpg

Same on the 32 inch cherry bomb.

http://photos.imageevent.com/germanp...m_DSC06577.jpg

3 inch down tube and elbow welded.

http://photos.imageevent.com/germanp...m_DSC06579.jpg

Passenger side done.

http://photos.imageevent.com/germanp...m_DSC06581.jpg

Same procedure on the driver side.

http://photos.imageevent.com/germanp...m_DSC06584.jpg

Plenty clearance.

G-Pete 10-23-2011 05:21 PM

The turnout is a clamp-on style with a rim. I tossed the original flange and made one which incorporates the exhaust hanger.

These are the Summit Racing seat adjusters $16 you can't beat that.

http://photos.imageevent.com/germanp...m_DSC06597.jpg

The two outer 1x1 inch square tubes are bolted to the tracks. the inner will be welded.

http://photos.imageevent.com/germanp...m_DSC06599.jpg

The passenger side has a 1 inch offset, because of the lever.

http://photos.imageevent.com/germanp...m_DSC06600.jpg

The inner tubes have an angle to confirm the shape of the Kirkey racing seat.

http://photos.imageevent.com/germanp...m_DSC06601.jpg

Drill markings for the studs of the adjuster.

http://photos.imageevent.com/germanp...m_DSC06602.jpg

Test fit of the seat base...

http://photos.imageevent.com/germanp...m_DSC06603.jpg

...and the seat.

http://photos.imageevent.com/germanp...m_DSC06604.jpg

DR and PA bases are finished and painted.

http://photos.imageevent.com/germanp...m_DSC06607.jpg

DR seat mounted on the base.

http://photos.imageevent.com/germanp...m_DSC06608.jpg

The pilot seat is ready to drop in. The seats are adjustable in height and lean angle.

http://photos.imageevent.com/germanp...m_DSC06609.jpg

This was the view on end of the day sitting in the seat for a few minutes and glaring at that - before cleanup and storing the project. Everyone who build one of these understand these moments:D

Really enjoying these updates! Nice to see the pic of the wifey...she appears well supportive of the project.

Just a quick observation...what happens if you need to change out a starter?

- Allen.

G-Pete 10-24-2011 01:10 PM

That question I asked my self in case of a starter failure. Well, two possibilities:


one-- I make a hatch and squeeze myself into the foot box, may I ask a smaller person to do that and change it out.

or

two-- I buy a new starter and if the starter fails in the future I have to lift the engine off the motor mounts and change it that way.


The donor starter worked just fine for the last 12 years. Close to 100K on the clock means about 4000 starts (daily driver). If the new one holds just the half of it, by that time I'm 85 years old and have forgotten why I came in the garage in the first place...


...I choose number two. :D

G-Pete 10-31-2011 01:35 PM

Driver side lower seat belt mount.

http://photos.imageevent.com/germanp...m_DSC06622.jpg

Upper driver side mount.

http://photos.imageevent.com/germanp...m_DSC06623.jpg

Passenger foot box completed.

http://photos.imageevent.com/germanp...m_DSC06626.jpg

Center frame completed.

http://photos.imageevent.com/germanp...m_DSC06628.jpg

With the passenger foot box angled, it is possible by removing the header to access the starter :D

Pete, thanks for taking the time to show me your car today.

VERY nice work!

Thanks for keeping us posted on your progress.

migge 11-08-2011 02:23 AM

Very nice work but I wonder what the weight will be, a lot of heavy steel.

Cheers
Migge

jbmatth 11-08-2011 06:02 AM

I was concerned about the same thing, but I'm sure the thicker steel will add strength to the chassis. What are you expecting the car to weigh once complete?

G-Pete 11-08-2011 06:25 AM

John, you're welcome -good to meet ya.

Migge, the 16ga steel weighs 2.5 pounds per square foot. (foot box). The floor weighs 5 pounds per sq/ft
15 sqf foot box - 37.5 pounds
13.5 sqf floor - 67.5 pounds
estimated 2 pounds of weld

total 107.0 pounds.

Before the foot boxes and the floors the car was on the scale and read 1574 pounds (incl Body and rims). As of now I should be somewhere in the neighborhood of 1700 pounds.
My target of 1800 pounds is out of the question. The estimate was based on aluminum foot boxes and floors. Seeing some of the "conventional" build ones after an accident, made me revise that plan. Just a flat tire spinning parts of it could crumble these alu foot boxes.
In the rear there will be added also steel splash guards (maybe 7 pounds).

To sum that up - just below 2000 lb is realistic.

That means 4.3 lb per HP. P to W = P/W
Better than a Lamborghini Murciélago (5.1lb/hp) or a Porsche 911 GT2 (6.1lb/hp):D

jbmatth 11-08-2011 06:40 AM

Very well explained, thank you for the info, good luck and I'm enjoying reading your build.

migge 11-09-2011 07:26 AM

Under 2000 is very very okay I guess :-). My last one was 2.134 lbs.

Keep us posted.

Cheers
Migge

dallas_ 11-09-2011 07:58 AM

Pete,
I think the minor amount of additional weight in the footboxes is well worth it.
Especially since you are still very light overall.

Does that also add rigidity to the chassis?

How much does the carbon fiber body weigh?
