    so....... to show the extreme diversity in "outlaw 10.5" the rules i found here are the PSCA rules. these rules allow a full tube chassis instead of a "backhalf" car and the fire wall can be move to facilitate moving the engine placement. the PSCA rules: CHASSIS / SUSPENSION: Any chassis and suspension combination that passes NHRA safety standards is allowed. FIREWALL: Moving stock firewall rearward for engine installation permitted. Each car in competition must be equipped with a minimum of .024-inch steel or .032-inch aluminum firewall, extending from side to side of the body and from the top of the engine compartments upper seal (hood, cowl, or deck) to the bottom of the floor and / or belly pan. like i said, IF you are going to build to that level of detail......do your homework. sanctioning bodies, geographic location, who sponsors the race, blah, blah, blah,... can all affect the rules and policies.

    mark, i can't say it's not thin....it is but, apparently it's thick enough for the saftey required. in a one to one car, you always have the option to go thicker. the rules on this are only the minimums. i got a p.m. requesting firewal shots on an outlaw 10.5. it really depends where you live and who's rules you follow. the blue mustang i've already shown is probably a good example. here's the PDRA's rule: 17. Firewall must be within 2” of stock location. Engine must remain in front of firewall. Firewall cannot be modified for engine placement. Firewall will be measured from front spindles to any point from cowl to bottom of firewall and from outside of factory frame rail to outside of factory frame rail. Modifications (i.e. Sloping, slanting, etc) outside of the factory frame rails permitted. Any vehicle that is over the 2" tolerance but less than 4" ADD 25lbs. Any vehicle that measures more than 4" from factory will not be allowed to compete. cecil county's rule: 4. Front Frame to be original O.E.M. type. (Stock front frame rails mandatory) Direct Bolt in aftermarket parts permitted. Firewall must be in the stock location. Engine must remain in front of firewall. Firewall cannot be modified for engine placement i down loaded these from the internet. if they aren't accurate or up to date. i can't help that. as you can see. the PDRA say's one thing, cecll county another. if you are getting "that" involved in your build. you should look these rules up and make a choice as to what you wish to do.
  7. 251 mph street legal (real)Camaro

    nick, can you tell me EXACTLY what's illegal about this car?
  8. Pro mod chassis help

    no problem mark. the firewall in a pro mod has to be .024" steel or titanium. nothing else. the driver's side floor must be steel and welded in place. (note the differences in the pics i supplied) the rest of the floor/ interior can be .024" steel, .032" aluminum or approved carbon fiber. as you can see there is a lot of different combo's you can build but, no aluminum or carbon fiber in the firewall or driver's floor area. hope this was helpful. i found a shot of the same car that shows the back of the interior. on this car you already saw the steel firewall, welded steel drivers floor, dzus buttoned pass floor and belly pan. this shot shows you steel around the driveshaft area, carbon tubs, flat carbon sheeting betweeen the tubs and a carbon fiber seat with it's insert.

    machinist mark, do you have what you need or is there some more shots you'd like? i'm trying to make sure i use the same car a reference as mixing and matching chassis designs will only be confusing.
  10. Pro mod chassis help

    mark and anyone else reading this. the print from chassis works is for a 94 -98 mustang. it's 101.3"wheelbase. 78-93 mustangs were 100.5". so if you print this out and either blow it up or reduce it to the correct size it should be a fairly close representation. the cage bars or other bars may need some massaging but it should get you in the ball park. the front and rear suspension mounting points should be particularly helpful. not many of the chassis companies put their prints out for you to view like this, so i'd take advantage of it. there are also helpful work sheets that can help you figure out rear end widths and other stuff. searching adds in magazines and then going to the manufacturers websites can be a big help. mark, don't worry if your build ends up being a pro street car. the '37 in my avatar is an ex-pro mod that in now my pro street car. hehe. they make wonderful street cars!!! a couple more pics. here is the all important driveshaft enclosure. the ball valves are for the nitrous.
  11. Pro mod chassis help

    sounds like you are off to great start. the mock up looks perfect...love the stance. here is a suggestion. on the frame you have started your main frame rails (the 2 in the center) should be one piece all the way to the front. it will make your model much stronger in the end. here are some chassis shots to get you thinking ahead. so you can plan your next moves. as an FYI. you should copy and save these pics as i won't keep them up here forever. keep up the good work.
  12. Pro mod chassis help

    these are more conventional 5.0, 4.9 or 4.84 chevy engines. charlie buck splits/ nitrous. roush /yates splits/ nitrous. scott shafiroff 2x4 / nitrous.
  13. Pro mod chassis help

    if you decide on the nitrous combo you want to do. i may have some very highly detailed pics from different engine builders. pat musi efi /nitrous. gene fulton splits/ efi . reher morrisn efi/ nitrous. sonny leonard efi/ nitrous.
  14. Pro mod chassis help

    here is a basic chassis design from the chassisworks site. here's the basic setup to establish the 4 link. front suspension, firewall and steering in one shot. i don't know the level of detail that you build too but, as you can see by being specific in your request. you can get the specific answers you are looking for.
  15. Pro mod chassis help

    if you look close some is in the middle of the tubing some is totally underneath. it's not always like this but, i'd say most of the newer cars being built are like this. this particular car goes a little further and runs belly pans.
