Thanks Sparky.

Is 9 point a requirement for you?
We run the same rules with a year delay, our rules say 7 point but we will be on a new book before I get close to finished.


Thanks

not quite yet-- but is hardly added anything to the cost---they grew out of the fact that with the head and neck device the straps need to come off it at 90---so it no longer pulled one down into the crotch straps..

Thanks, I will as Bob Stroud about them when I order my belts, he seems to be the only supplier that recertifies belts and he was pretty helpful when working through my chute requiquirements.

We only run once a year, I'm going to keep all my safety kit including harness & chute in a Pelican Case or similar that is airtight to keep them decent.

T-M  when we weld the tabs in I will try to remember to take picts of all attachment points. Andy and I noodled some more about the shifters and such in this car----will have to be creative with out any LIQUID calories---- between the 3 of us we are going to have to loose a combined 100 lbs.  :cry:

they Mayor's reference about Allisons "LSR is a lifestyle"---well to do LSR in this new car we are going to have to HAVE a lifestyle change  :cry:  this thing is going to be TIGHT  the exhaust will be a challenge as well as fitting US in!!  so much for wanting to be fast----we will do it we do want to be fast!!

We got a note from Woody today saying that he was working on our final config.--- this is his teaser   :-)

This is pretty close to what we think we are trying to build---

I read in an AERO book one time that an open wheel car has 40-60 of the total drag in the tires---with the help of Woody and his CFD, opinions of Pork Pie and several others, and the input over the years of many we think we have a good results  64% of total drag in wheels and tires---that is with no body air leaks:

But as Joe Amo and so many others have said its just a dream untill you put it on: "The Great White DYNO" 

Here's to August and a possible visit with "the Mayor"  :cheers:  :cheers:  :cheers:

Sparky;

You can increase that percentage even more if you run big wide tires.  :-D

67.7% with MT's on the back!  :-(
Sparky, has Neil been spying on us?  :? :-D

I wish GY & MT would give us 3D models of the tires at speed. Me thinks they are not really so round!  :-o

Sparky has agreed and I will do some articles for BRN about his project and we'll leak some stuff here, too! So stay tuned!  :cheers:

Sparky,
Many thanks for lettings us see the results of some of Woody's work. Couple of questions about the latest: 1. Are the small rear facing ducts that I see just above the rear axle fairing your exhaust outlets? 2. Your axle fairings, both front and rear extend past the rear of the wheel, any thoughts of ducting some air through the fairing and to the back of the wheel to fill the void that is there? It is going to be a really great looking car you will need to really work on body fit and smoothness to keep the friction drag down to take full advantage of that great shape.

Not much matters and the rest doesn't matter at all.

Correct on the exhaust Rex , Woody and I think that we will build them in such a way that we can "Play in that area"---bottom line  we will make them moveable to change the angle of attack because in that area he could not make them very effective other than fairings but he did get some down force out of them

from rear:
the upper bar is for 8-9 upper or outside straps that are at 90 degres to spine,

the lower bar is for the 3-4 underneath or inner shoulder straps that pull you into your crotch straps.

Drivers box:
# 1 is the 7 strap attachment point that keeps the lap belt from riding up off you hips on this car we but it between our heels because of our very reclined position

# 2 shows the attachment point for the new out side 8-9 straps that come over the Head & Neck restraint on top of the 3-4 shoulder straps then down at a 90 angle to your spine

#3 shows lower tube that we will attach the 3-4 shoulder straps to the upper tube is the attach point for the 8-9 outside or upper shoulder straps that pull you in to your 5-6 crotch straps.

#4 shows the attachment tab points  at  the hip bone, for the 1-2 lap belts and the 5-6 crotch straps
