slngsht Posted March 10, 2011 Posted March 10, 2011 so... time to start something new. give me some opinions. my idea right now is a small two seater... target 800-850 lbs. This would be a mid-engine car, chain drive. have a line on an '07 CBR 1000RR for $1k, including electronics, harnesses, exhaust header - not including radiator. give me whatever nuggets of info you think will be useful.:lurk:
WestTexasS2K Posted March 10, 2011 Posted March 10, 2011 Abandoning the 7? I would think an EXO style frame would fit the bill. Something along the lines of a scale down RCR superlight roadster. 850 lbs is a high goal. Most likely need moly tubing to hit your weight.

Arya will take over Frankn7 I wanna go to something much closer to my Formula SAE days Yeah, I'm not that concerned about bodywork - minimal to get it on the road. Curious why that RCR car weighs 1300-1400 lbs. Seems a bit on the heavy side. Is it supersized?
S1Steve Posted March 10, 2011 Posted March 10, 2011 Yes you are allowed here !! LOL What are you planning to do with it. Street Legal ? AutoX beast ?? Track Car? That would be the ? I'd be asking myself... Make it big enough for Arya and me... ps. Arya's going to give me a call for this weekend...
slngsht Posted March 10, 2011 Author Posted March 10, 2011 good question about size... don't know... this one is going to be designed in CAD, and since now I have access to a CNC Router, a CNC plasma, and a CNC mill, gonna have lots of little parts I just couldn't make before. It's going to be chain drive (engine sits same orientation as in the bike), enclosed diff (housing just around the gears), with single rear disc. I'm kind of thinking about doing inboard brakes with halfshafts in the front... That does add overall weight, but should provide outstanding wheel control by making caliper and disc part of the sprung weight.
JohnCh Posted March 10, 2011 Posted March 10, 2011 We need an admin to move this to Off Topic :jester: You should check out ZCars Mini web site for inspiration. They do a bike-engined, chain driven, rear drive Mini conversion that might give you some ideas. The web site itself isn't overly helpful, but the downloadable brochure has some nice photos of the mechanicals. Also, look at http://www.dpcars.net/ Dennis has taken some very creative approaches to weight saving with his dp1 and dp2 designs, and has documented it quite well on the site. -John
readysetgo Posted March 10, 2011 Posted March 10, 2011 I keep following this guys build logs on "locostUSA" he goes by "Pook".His builds are killer.... http://www.locostusa.com/forums/viewtopic.php?f=36&t=8834 There are a couple of them, http://www.locostusa.com/forums/viewtopic.php?f=36&t=9904 The first link would be the closest to what your thinking...I think...
slngsht Posted March 10, 2011 Author Posted March 10, 2011 Hey John, Yes, Dennis' site is amazing... He has taken car design for a small shop to a whole new level.
JohnCh Posted March 10, 2011 Posted March 10, 2011 I stopped by the shop on my way to Monterey this summer. He is really doing some amazing things. -John

slngsht Posted March 11, 2011 Author Posted March 11, 2011 damn, I miss the old days. They've come a long way. Got any more info on the car?
MHKflyer52 Posted March 11, 2011 Posted March 11, 2011 Mazda, Why not just buy this and finish it. http://cgi.ebay.com/ebaymotors/Replica-Kit-Makes_W0QQcmdZViewItemQQ_trkparmsZalgoQ3dLVIQ26ituQ3dUCIQ26otnQ3d3Q26poQ3dLVIQ26psQ3d63Q26clkidQ3d7457263781516862550QQ_trksidZp3286Q2em7QQcategoryZ7251QQitemZ270714405925#ht_1692wt_1165

Out of my budget range, and against my tinkering nature. LOL I noticed it has no diff in the back... something I have been contemplating. I think you can make a suspension that can handle fine with no diff when you're pulling g's, like in autox... not sure how fun that car is to drive around a parking lot.
scannon Posted March 12, 2011 Posted March 12, 2011 It has a diff. Custom build Limited slip chain diff

readysetgo Posted March 14, 2011 Posted March 14, 2011 He has mad skills. Amazing stuff. Thats his car on ebay...."Pook". Thats the car in the first link....
slngsht Posted March 14, 2011 Author Posted March 14, 2011 Thats his car on ebay...."Pook". Thats the car in the first link.... Nothing gets by me! :rofl: At this point I'm leaning more and more towards a single seater super light car.
Boxologist Posted March 15, 2011 Posted March 15, 2011 damn, I miss the old days. They've come a long way. Got any more info on the car? look up the U Maryland FSAE team. Ibeleive a few of them are still in school because last Memorial Day they were telling me that bthis year they were going to play w/ active aero. a Formula car would keep u off teh streets unlike Franken7, but if u were planning to go autoXing more often, FSAE as a class is open to non-students, etc.
jlumba81 Posted March 21, 2011 Posted March 21, 2011 (edited) Looked at some of those fsae build videos and its amazing what they are doing. Using autoclaves and making carbon fiber bodies and parts, milling their own parts, etc. Also some neat turbo and supercharged bike engines. Also using cfd to design their floors, diffuser and wings. Neat stuff. Here's a nice promo video from the university of washington - Edited March 21, 2011 by jlumba81
