We have been working on a flat bottom for the Cobra and were unable to run it again by the end of the season so we set the Vantage up and took it to PIR.

Hey thanks - glad your enjoying it. I am getting excited to run it. chr

We are on our 3rd major revision. I did some study on the Viper and found out several were burned to the ground because of fire in side the sill surround. We modified the cover so that we could attach it with dzus and we could remove it without having to open the door. This necessitated another...

With the pipe hung with proper clearance we had to modify the rocker panel and push it further outboard. We are bending the new panel and will need a new floor panel to accommodate. We positioned the rear tire and reset the ride height and the bottom of the floor is within 1/8" of where it needs...

It's a slow one - LOL chr

I am running the same. Something to consider - the arrangement we are using for the cooler is un-shrouded. One of the things I plan to do this year is box the steering HE. It suffers from the same problem as an un-boxed radiator. Boxing it will keep high pressure in front and not let it leak...

Curious - are you using the stock cooler?

Some progress We've looked at a lot of options and have decided to hard mount to the door sill. The engine is hard mounted so we are going to weld in a flex coupler at the head of the side pipe. Our thinking is we'll break it or we won't. We are fabbing brackets out of 16 gauge (.062) steel...

DEI insulation. Will wrap all the way under door and attach to door sill. 2.5 dia Burns 17 x 2.5 x 3.5. I have no idea if this will be enough. We are going to see about making it easily removable. If we can, we will run a straight pipe on a couple of tracks with no restrictions. A...

This pic shows how far we have dropped the floor. We have run partial sheeting for several years unfortunately it was not flat, except at the outboard section. The inner section followed the SFCs which made it rather swarfed (still helped us get over turn 9 at Portland :)) The bottom of the...

Here is our latest rev with the outlet properly placed. This is an L shape we are using to box the exhaust tunnel. It is riveted to the pinch weld. The horizontal surface gets riv-nuts which the floor will attach to. The floor closes the tunnel. The door sill down to the horizontal get DEI...

We have big plans for 2018. Our goals for 2018 1) Rebuild the IRS with a Full Tilt kit 2) Re-gear to 3:73 3) Construct a full flat bottom 4) Construct a rear diffuser 5) Put the car back on X2s which will leave us at 2.5 above ground We have been at it a couple of weeks now. Originally...

I installed an AGR Cobra R spec-ed rack in my 03 Cobra. I got a hand full of days (7?) out of it and blew both seals. I spoke to AGR and they said the rack was not built for track use. Can anyone give me ideas to what may have caused this? I assume over pressurization, but why would I be...

Just a heads up - I purchased an AGR Cobra R spec rack for my 03 Cobra. It is a track car only. It maybe has 7 track days on it and both seals are blown. I was going to purchase another, but I saw a review at Summit and the customer had purchased the same rack and blew it up tracking. When he...

It seems like I posted the boxed cooling but I cann0t seem to locate it. Below are some pictures. You cannot let air leak around the heat ex-changers it must be a sealed system. The air will follow the path of least resistance. The idea is to slow the air down and stack it in front of the...

Also not sure what thermostat you are running, but you should consider this if you are not running one. They have your Mach 1 listed.

chronomitch - I do not see in your list that you have fully boxed your cooling system. We run an 03 Cobra with 2 drivers in HOD and keep it cool all day. We did not start out that way. It is very important to box the radiator. You cannot let the air leak around it. If you have not done this it...

Don't get upset. While the whole "your going to kill yourself is a distraction" the point of the node is important. The car you posted is dead ended into a node from both sides. Look at the tubes approaching the joint from the A pillar. I tried to mark them in red. You can easily adapt this to...

+1 You can just see the bottom of the exhaust - that is how low the floor is. I have checked mine several times with a level. We plan to build the ceiling @ 8 degrees. At 8 degrees from the floor there is a gap between the bottom of the bumper and the ceiling of the diffuser - that is how...

I've been meaning to post up some dimensions for the Aerocatch pin block. I got a recent request from a member so here it is. The as-built drawing below shows both pin holes for ease of making the drawing. You only need one per block and the pins go to the inside. The pins are metric I believe...

I saw this at Corner Carvers and found it quite informative. http://www.motoiq.com/MagazineArticles/ID/3974/How-to-PROPERLY-select-and-size-TIRES-for-PERFORMANCE.aspx chr
