Ok seriously, you could build a 914 to compete at the nationals, but only if one would be willing to spend some serious cash, just like the competition. To be competitive you'd need a big 6 (375-400 hp) coupled with the right transmission/gearing and tire combination. JP's two speed approach would work great. Actually the Beast would be a good starting point, although maybe a bit heavy, but the big motor/transmission combinations are right now sitting up in Reno. Like a 400HP-normally aspirated 6.

Have you looked at E-Modified SCCA rules. 2056cc ????? really you have no clue. Yeah????? Never said anything about 2056cc or a 2.5 boxster being in E mod? I just was comparing platforms with similar power to weight as a comment? E-mod rules allow up to 3200cc's. Perfect for a Boxster S motor powered car - Which rumor has as the E-mod car in question - Have Jake do his magic on the 3.2 and I bet it would put out over 300 HP - then strip that sucker down to under 2000 lbs (which would be quite easy). I suspect you could get a boxster down to 1800 lbs if you worked hard at it. We are likely to see a Boxster E mod at Nationals before a 914. But its nice to know we have a few "rules experts" like you here. LOL! For me I'm satisfied with going to local SCCA, UFO, PCA events in my little underpowered OSP Boxster and occasionally beating big bad Cobras and being beaten by very well driven Miatas. No delusions about podium placing at nationals for me. I'll leave that to you and JP. This post has been edited by grantsfo: Mar 26 2009, 03:51 PM |

So how do you think a boxster could be lightened to 1800lbs? Please be specific. Thks. Glad you asked because I have been thinking about this! Strip car down to chassis - remove undercoating, pull all that uneccesary and heavy skirting from underneath the car, pull fender liners and structures that hold rear bumper on. Remove rear bumper and all structures that hold it to the car. Replace fenders, doors, front bumper, hood and trunk with CF. Gut entire interior and put lightweight aluminum dash in the car. Lop off the front windshield, remove the rear convertible top cover (damn that thing is heavy!). Remove all heat shielding, sound insulation, useless electric blower motors and crap from engine comparment. Replace the stock fuel tank with a small fuel cell. Remove all radiator ducting, motors and fans. Pull windshield wipers, motors etc, pull heater core ducting etc. Use 16 inch Jongblode wheels with Hoosier race slicks (Thats easily a 50 to 60 lb weight savings over what specs use). Lightweight headers straight to lightweight mufflers. Pull headlights out. Build a lightweight AX cage - Boxster chassis doesnt need nearly the reinforcing the 914 does. Put either aluminum body PSS10's, Motons, ect on the car. Cut out front and rear crash structures - they dont serve any function on an AX car. Install lightweight flywheel and clutch assembly ( thats a huge savings too) Use aluminum brake hats, use a single CF race seat. Spec cars dont even come close to getting all weight out and some are below 2400 lbs! It would look something like this but with all CF panels doors, no windsheild and a much less beefy cage. (IMG:http://www.boxsterspec.com/uploads/monthly_02_2009/post-133-1233641444_thumb.jpg) Honestly I dont think you would have to swiss cheese the car to get there. You would just have to be motivated to have a AX only car. This post has been edited by grantsfo: Mar 30 2009, 07:58 PM |

But in any event be specific about what weight you are assigning for each set of items outlined so we can compare factually. |

Nothing new here Grant, sorry. Maybe 2100 at best and then I'm giving you 350lbs less than Bill Pickering's 2450# stripped car. Expereinced AX car builders dont need to do anything new. All parts and techniques are known. Its not magic! FYI Bills car is not the lightest of the spec cars and getting 350 lbs out of his car would not be difficult. I believe he still has an aluminum top on his car and I think he has a stock flywheel. Spec cars leave tons of heavy parts on due to rules. Youre on target for road race weight. There are heavier fiberglass body road race Boxsters that are already in the 2150 to 2200 lb range and they have full road race cages, windsheilds, tops, bigger motors, all the road race safety sysems, 3 radiators, heavier road race wheels, etc. I'll meet half way and say 1900 lbs is realistic for an AX car, but 1800 is achievable with focus. Still not bad! I hear people say that there isnt much opportunity with Boxsters, I disagree. Lots of stuff can be pulled or replaced with much lighter aluminum or CF. I'll leave the specific part weight look up to you! ....Unless you want to pay me for that analysis? I charge my discounted rate of $250 hr for AX build consulting (IMG:style_emoticons/default/happy11.gif) ..no customers yet (IMG:style_emoticons/default/lol-2.gif) Oh yes I did keep the few secret ideas out of the post. Always have to have something that keeps people guessing how it can be done. But I assure you my number is achievable regardless of what the "experts" tell you. Back to your 914 and SCCA Solo Glory. I would take 222, chuck the VW motor and put either a turbo Subi or turbo rotary in there. Tune to 400 hp. Pick proper gearing. Then get some real wheels and tires on the car to put power down. That would be a hero maker. This post has been edited by grantsfo: Mar 31 2009, 09:37 AM |

Its always fun to dig up old "Doubting Thomas" posts from my biggest fans! My full SCCA road race legal caged all steel fendered Boxster just went into 2000 lb range today! If I wasnt intent on Solo FP class and wanted to go Modified class we could pull another 100 lbs out of the car and go into 1900 lb range just as I had predicted over a year ago! My "agenda" has always been to help put the Boxster platform into competitive light in grassroots motorsports. Looks like we are getting there! (IMG:style_emoticons/default/bye1.gif) |
