mender Posted March 7, 2018 Report Share Posted March 7, 2018 I did mine according to the rules, then added extra structure around the cell plus an extra layer of steel under the car and on the side for even more puncture resistance. Two layers of steel protecting the bottom of the cell and three layers of steel on the "exposed" side. The door is plastic so I added thick sheet metal to the NASCAR door bars. One of my design goals is to be able to jack up the car using the structure supporting the fuel cell. Link to comment Share on other sites More sharing options...
Technical Advisory Committee Andrew D Johnson Posted March 7, 2018 Technical Advisory Committee Report Share Posted March 7, 2018 Tips? Do not install cell behind rear shock towers, install cell completely behind driver. Do not have any plastic hose exposed. Link to comment Share on other sites More sharing options...

Do not install cell behind rear shock towers, install cell completely behind driver. Do not have any plastic hose exposed. 22 minutes ago, Crank Yankers Racing said: Well mine is wrong then I'm sure Tyler states this because a fuel cell on a RWD car is usually placed behind the axle, due to the driveshaft being in the way forward of axle. When the Viper was designed, the fuel tank was situated ABOVE the rear axle in order to be safer, even though this meant the rear CoG was being raised. (Yes, racers designed this car.) There are trade offs in most everything you do, so for all the guys vehemently arguing that you have nowhere to safely install a fuel cell due to RWD, you are sadly mistaken. Over the axle, with roll cage back stay bars extending past the cell, and proper framework, a cell can safely be installed. Link to comment Share on other sites More sharing options...
Technical Advisory Committee Andrew D Johnson Posted March 7, 2018 Technical Advisory Committee Report Share Posted March 7, 2018 When I backed my car into the wall at the WRL race last year, the rear of the car up to the rear shock towers was completely demolished. The fuel cell was untouched. Link to comment Share on other sites More sharing options...
ABR-Glen Posted March 8, 2018 Report Share Posted March 8, 2018 It's a dramatic example, but there's really nothing back there right? It just crushed up to the point there was some actual structure. Which doesn't mean if there was something back there that it would have also been crushed. Link to comment Share on other sites More sharing options...

Technical Advisory Committee mcoppola Posted March 8, 2018 Technical Advisory Committee Report Share Posted March 8, 2018 Fuel cell and surge tank are in stock tank location, forward of rear axle on a FWD Focus. 18ga steel box that the cell bladder sits in, with 18ga aluminum cover over the top of the lift pump, surge tank, etc. Braided lines for everything including the vent that runs up to the top of the rear hatch. Small area of the clear filler tube is exposed to watch and prevent overfill during pit stops. Approved in 2017 by Chumpcar and WRL Tech. Link to comment Share on other sites More sharing options...

Stock fuel tank vent lines and fill necks may be altered and/or relocated. that will take out the vent as said in rules Ron-e but we plan to be in the rules, I gust you would be mad if I install the 2009 VW Jetta TDI 2 CR with an automatic DSG as an engine swap ( on list now) 50 + for engine swap -50 points for automatic zero points added, 18+ gals of diesel we can run 5 hr on 14 Gal so that is that is fueling ever thrid driver change so we could get a drive in and out in 60 sec . right, every pit stop 1-2 lap jump ahead and like 350 ftlb to the ground all in at 1800 rpm!!!

zack_280 Posted March 8, 2018 Report Share Posted March 8, 2018 DSG may not be manual, but it ain't automatic. From the most credible source for information on the internet: A direct-shift gearbox (German: Direkt-Schalt-Getriebe), commonly abbreviated to DSG, is an electronically controlled dual-clutch multiple-shaft manual gearbox in a transaxle design, without a conventional clutch pedal and with fully automatic or semi-manual control.

DRVOLKS Posted March 8, 2018 Report Share Posted March 8, 2018 VW sells it as an automatic and I do have an email from tech it is an automatic. It does have a valve body in it so I would go with that. Bob Mann Link to comment Share on other sites More sharing options...

Not mad, sorry if I came across that way. Follow the rules, build it, if it turns out to be the unicorn you think it is then be prepared to be slapped down, has happened numerous times in the past. Assigning 500 points would have been Mike's first stab at it, he may adjust if it puts a quality field down by 5+ laps. Link to comment Share on other sites More sharing options...
DRVOLKS Posted March 8, 2018 Report Share Posted March 8, 2018 I am running the 22 gals because in Lemon there is no real limit on tank size. I will stuff it to meet chump spec. It will be hard to get it under the 500 pt when it started at 490 pt. I bring up the fuel cell here because I got a lot of heat at AER when I asked about a good fuel pump to use. they say no clear hose must seal everything in metal!!! I think I will do as mike did above and show the clear hose to watch fueling if we ever to go somewhere like AER just slip a cover over it Link to comment Share on other sites More sharing options...
ABR-Glen Posted March 8, 2018 Report Share Posted March 8, 2018 I'm not sure how the guys in AER do it, but I've seen people cover the clear plastic filler hose with a metal braided sleeve before. Looks pretty effective, but not technically 100% coverage. Link to comment Share on other sites More sharing options...

Gearhead_42 Posted March 12, 2018 Report Share Posted March 12, 2018 Installation tip? Do not order a replacement steel can from ATL... their estimated ship date has slipped over two months at this point. It's almost like they're hoping I cancel the order and have to reorder at the new higher price or something... Link to comment Share on other sites More sharing options...
