Ok I am a 28 year old who wants an Indy car and I have some money to play . I need some help though Iam trying to find the dimensions to a Formula 1 car . If I could get all the dimensions it would make life better and easier than trying to weld from scratch . I was and still am interested in the Indy Street but I feel that I could improve on the car drastically (I dont care if I cant spell). I would like to weld up an aluminum frame and save myself 350 lbs on the indy street car which uses mild steel . If anyone could help I would apreciate it. I also want it to replicate an Indy car not a Street Indy so they couldnt help me there. God be willing I will live long enough to make one . |

Well, I don't know dimensions, but there are people here who do. I would offer only a little bit of advice, though, about using aluminum. First off, it's harder to work with than steel - make sure whoever welds up the frame knows what they're doing. Next, although aluminum may weigh in at about a third what the comparable steel would weigh in at...remember that it's also only a third as strong; you're going to have to have some serious triangulation and word done to make that aluminum chassis as strong as a comparable steel chassis would be. You may want to look at a full monocoque chassis. Just my .02 cents. Your pal,

Also remember that Aluminium has different stress properties to steel. A part made of aluminium that is under twisting stress will continue to deteriorate until it snaps. Steel won't. Just my 2 cents :)

Well I have started drawing up blueprints and plans . I know that the fatigue resistance of aluminum is alot less that that of steal so Iam going to complete the a arms and various high stress point out of cromoly . I am still trying to get engine geometry down . I have not decided on what transaaxle Iam going to use . I have had all sorts of options thrown at me and I have yet to find the perfect combination . The a transmission should be located in line with the motor and I still dont know what tranaxle to use . I dont want to use a 425 ,that would offset my differential or put to much stress on my drive line or Cv joint connecting the two . And if I put the driveline straight back then that would offset the differential causing my drive lines to be differnt lenght making my a arms have to be (diffrent?) I have recently considered the use of a vw transaxle , cheap and abundant . I have to research more before I start welding . Any help would be nice but please dont try to burst my bubble this is a real project that is going to take time and research. Thank you to those that posted Your advice is heeded.

You may want to look at a FWD Subaru Transaxle. They are cheap and abundant and very good quality, but if you're going to put a worked 350 in front of it you may have reliability issues.Chromolly is a little bit over the top. What you can't build from black or HT is probably not worth building. Chromolly is a gymic when used in the auto industry, so unless you're building a pulp mill or power station, don't wast your money.

Well God be blessed . I spent the day searching for parts ,such as a transaxle and brakes . Well I was about to give up for the day when I was told about a Porsche in the back of somones yard . Well I went on a hunch and went and checked it out . It was a wrecked 944, disk brakes transaxle and motor . The guy told me he wanted it gone and didnt want anything for it . So now I have brakes and and spindles and transaxle drive shafts the whole works. I am so stoked , I just dont know if I can adapt this tranaxle to a 350 yet . I have been telling all who help that I will have there decal of name put on the car . Thank you all .

The 944 transaxle is sort of a modified Audi 016 transaxle; it has different gearing (I've been over this already with the M40 - the 924/944 has a 3:88, the 944s (turbo) has a 3:28 ring and pinion) and I believe that in the Audi box 4th and 5th are overdrive, whereas 5th is the only overdrive in the Porsche. Also, the gears are apparently welded to the shafts in the Porsche. Oh, and one really important thing: the transaxle is split into two "ends" with a torque tube in the middle. This gives the Porsche better weight distribution and transfers nicely, but - because of the torque tube, there's not provision in the transaxle for a clutch...which is pretty important, I believe. Hope that gives you some direction. Your pal,
Meat.

I havent gotten the chance to tear it apart yet . But what I understand you are telling me is that the clutch is up at the motor and there is a driveshaft running back to the differential . It looks like I would have to get pretty creative to make it work . What happens if I mate the differential(transaxle) with the clutch ,in other words just take the drive line out of the picture?

Hey burlguy. What ever happened to your endorsement of www.indystreetcar.com? You have said, and this is a quote... "They are legit as far as I can tell and God be willing I am planning on getting one of there cars."I'd like to know more about the wonderful Indy Street Cars I have been unsuccessfully persuing. According to your words, you have visited their business, spoken to the crew and even went as far as to ask me to mention your name. Now you are creating blue prints and looking for transmission parts. Yet you have "money to play." Why don't you just purchase a turnkey from the non-existent imaginary indystreetcar.com? You can also get a kit in three imaginary stages from the imaginary place you visited.

The whole thing looks pretty legit to me, although I'm not sure I'd be seen driving one of those around... Different people have different tastes.

Well there is always one guy(or kid) out there that has to try to spoil the fun . I am not him . Zem I think you better check the post again and see if I had ever visited them or said that I had . I will only do this once ,that is answer to an accuser and then I will just let you be . As far as buying a turnkey ,I dont have 23,000 to spend I have 14,000. Also they come with a v6 I like gm 350's . Also I have done some math and I can build a car with 12,000.00 and have one that is about 200 pounds lighter with adjustable coil over shocks and a tig welded aluminum frame . So enough with bickering . Iam still trying to learn about Formula 1 setups . I have yet to design the progressive rate suspenion with inboard shocks . After I have the drive train down I will be able to use those measurements to distribute the weight within the wheel base alotted . I havent started constuction yet but I know this will take time . I am not sure if I will even complete this project but I think about it every day and I find more ways to make it better . Somthing that I did find out was the turbo models from the late 70s had as much as 1200 hp and they had the motor forward about a foot more than currently . I am thinking this might be a good idea for me . Any advice is welcome and I guess I will just part the Porsche out . God be blessed.

Why would you TIG weld it? Why would you use aluminium?I mean no disrespect dude, but it's obvious you're not an engineer so perhapse you should consult with one before you begin.

Well through all the ups and downs I am still making progress. I bought a Miller Tig welder and have been working with some Ideas . I was also able to find somone to trade my 944 for there 914 . So now I have a transaxle . I need a place to build it though so Iam going to have to buy a house . I will know if my house loan goes through today . Some times it just seems to fall together so easilly , Praise God .
