Thanks again Eric!
Thanks again Ben! (hopefully, I'll get the fuchs painted and on it before you see it in July)

last couple of shots.
guess I should close this thread down.
Laura took a coupld of action shots for me at the race.

Here I am coming out of a hair pin corner:

Here I'm actually passing someone..

whoo... hooo...

Ok...
this isn't so much an update as it really is just me storing a few more pictures I wanted to keep together.

too lazy to do a blog at this point.

This one is the underpan for the front MC and fuel pumps.
Its aluminum of course:
brant
Here is a shot of the stainless grill over the brake ducts...

Its amazing how much rubber gets inside the vented rotor without the screen:
brant
About a month ago we trailered to Grand Junction and got onto a chassis dyno to tune the carbs. We were there from 8am until 5:30 and got 12 pulls in during the day with lots and lots of tuning inbetween. The temp grew significantly from 90degrees to 104F.....

very happy with the results.
I picked up a stutter for sure, but I'm going to customize/modify a set of emulsion tubes to try and cure that. Over all still very happy with the dyno work and the motor for just being such a stock 2.0S

brant
a tiny bit more legible. This was at the wheels, at altitude, and at 104F

brant
We started refinishing wheels.
Dad did all the work.
only the first 2 are done so far but they came out great!
they were a bit curb scratched when he started. He hand polished them and then we masked and shot with a wheel paint:
brant
7 inchers to replace our cookies:
brant
new tires will be fun too:

holes come natural to a 914....
if you don't believe me, ask anyone.

thanks Dion, thanks Michael!

race car update.
she is just about ready and serviced for the upcoming season #2
I don't have pictures of most of the updates we did.
I'll get them later... they are all pretty minor anyways.
the neatest is the front hood and thats not ready for show yet anyways.

Dad is doing his vintage school in one week to get a liscense with that group.
should be a very good time


Here is the new muffler bracket.
smaller, and lighter than the old one.
about 50% weight reduction in just the bracket:
brant
The feet to this bracket are clamped to the muffler with stainless clamps.
my welding isn't up to this level and I didn't want the vibration to cause failures so I didn't do the welding.

The welding is amazing.
a guy in longmont runs an alloy speciality shop.
he is good enough that he does some helicopter work.

pretty:
brant
I have a few updates to add.
I have a few less than stellar pictures of recent developments.

First here is that muffler bracket installed.
saved a few ounces over our old one and should provide a more smooth aero shape under the car:
brant
Next is my clutch/flywheel upgrade.
didn't yet finish the install, but things are started and should be ready for the next race. Using a Tilton system, which hopefully will provide quicker acceleration-revs.

really excited to try this out and also nervous about the combo of using it with my new gearing:
brant
my crappy bathroom scale tells me its 14lbs with the complete flywheel, pressure plate and clutch. Not as light as I anticipated, but the big key should be "where" that weight is located.

front side:
brant
Here is the neat one...
got the new tranny..

really looking forward to trying this one out.
gearing is: F / J / O / S / V

should provide an awesome combo for both long and short tracks since all 5 of the gears can be actually used.

AJRS has tested this set up in bigger and much more powerful motors (including his own for 2+ years) so it should be amazing!

The specs really look decent and I'll post a chart. The MPH between gears looks promising:
brant
That was weird... I've never tried a chart before.

Anyways. The new tranny has a quaffe in it
We did a lot of research and actually found some information that the quaffe could potentially be better than a ZF style diff for a 914 track car.

guess time will tell

I'll not have reverse gear anylonger due to the active first.
infact the magnesium case has to actually be welded to make this work.

the case was quite corroded, and we were advised to provide some type of sealant to avoid further corrosion. This led to an interesting theoretical discussion about what color would shed heat best...

one theory is that silver reflects.
however, a lot of things that need to radiate instead of reflect are actually painted black. For example... radiators...

alot of the serious sand rail guys go with dark colored 914 tranny's...

anyways we decided to try black and see.
I doubt I'll ever be able to tell a difference
we used epoxy appliance paint:
brant
Update from doing a little wrenching.

got the old clutch out and the new clutch/tranny in.
haven't yet finished up installing all of the exhaust or axles, but its pretty close.
my next race in Hastings was postponed and I didn't get selected to run the vintage exhibition at the Denver Grand Prix (street course sounds so fun!)
So at least there is no time crunch to finish this now.

Anyways, I have a few extra pictures to preserve of the changes.
Here is the old clutch flywheel combo that came out:
brant
Its a stage 3 AJRS combo
a "window'd" flywheel
10lbs flywheel:
brant
We were running it with the 911S aluminum pressure plate/disc
The full set up was 20lbs.
(10 for the flywheel, 10 for the disc / pressure plate / throw-out / bolts):
brant
side by side:
brant
So the new flywheel is 6lbs, and the full assembly including bolts, weighs in at 14 total:
Aaron Cox
schwing!

nice parts!
brant
6lbs net... but most importantly all of the weight is moved inward and the mass doesn't reciprocate in as large of a circle:
brant
last couple...

here is a pic of the aluminum engine tray dad produced.
its for keeping dirt out of the engine bay:
brant
and finally the "after" shot of the aluminum front skid plate with battle damage.

here is what happens if you put 2 wheels off the outside of corner #7 at pueblo.
even worse, I bugger'd one of the pipes on the right bank header..

its still useable though
and "its just a fleshwound"
brant
Its time for a few more updates.
we did another corner balance with all of the changes over the last year.

we added weight with:
- TB differential
- aluminum motor pan
- aluminum skid pan
- wide band O2 sensor

Here is a picture of our innovate installed:
brant
and here is our read out. Its the XD-16 guage by innovate:
brant
A little bit better picture that shows out placement. I used it this weekend to rejet at a race in Hastings, NE.

works very well.
allows real time info that is far superior to seat of the pants jetting.

I had the car running the way I "thought" it should be... and then found out I was lean (14.0+) above 7000rpm. No way you could tell that without the data, as the car felt just fine:
brant
On the good side of the great weight debate... we did a few things during the last year to save weight. Such as:

- lighter clutch and flywheel
- new muffler bracket
- lighter air filters
- and this little hood project

Here she is unpainted:
byndbad914
Brant - looking good thumb3d.gif So, two questions (maybe I missed this)

1. You mention doing a current corner balance, but what is the current weight of the car?

2. How much weight was removed from the hood (i.e. what was the weight before, then after the holes)? Curious as I may just stick with my nice stock hood instead of fiberglass if what you did really got the weight down...

It doesn't really get the weight down as much as you'd like.
its more of a visual thing at this point and showed only a 5lb savings
(with MANY MANY hours into it)
I'm required by rules to keep a metal car and metal fenders/hoods

let me double check my numbers..
I had already removed and lightened it before, so I think I was at 35lbs pre
and 30lbs post drilling.

regarding total weight...
this one I'm happy to talk about
we were able to get the corner balance VERY close this time
using the formula for ideal, we were able to get each corner within 1.5lbs of ideal

we re-aligned too and that came out pretty well with -3 camber on the rear now.

I shed 13lbs total (still with my heavy kumhos)
here is the new weight:
brant
more front hood (post paint, artsy shot):

honestly, I am really impressed with your car. Obviously I have a little bit different school of thought (build a brick sh!thouse and put 525HP into to get it around biggrin.gif ), but the fact you have a 914 that still has the windshield, targa top, and steel body and so forth down at 1837lbs is pretty cool. You really put a lot of effort into making a lightweight 914 racer, not just "914-based" racer if you catch my drift.

I am lazy enough I wouldn't sand the roof down, I would just get a fiberglass cap for instance, which is why your efforts rarely go unnoticed wink.gif Solid job on a sweet car.

thank you sir..
that means a lot!

Brant,

I didn't know that there was anything going on in Hastings last weekend. I knew they are developing a track, but I was unaware that they were having events other than demostration runs.

Next time you make it back that far give me a shout and I'll get the "Omaha Crew" to come out and lend you some moral support.

I met a couple of people that came down from omaha this weekend
next year for certain then, you have to come!

I was having fun reading this and thought I'd throw in another pic.
lots has changed... I got T-boned by a spec miata along the way
some improvements, some repairs, different flywheels, tranny's and a new lump of gold is on the way...

I did some wrenching yesterday as a matter of fact
here is the new carter fuel pump with built in regulator
its on a custom aluminum mount that dad made (with plenty of holes):
brant
also in that picture (and this one) is the new 27mm hollow SMART bar:
