    Once it will be 100% CF ^^' The dashboard I do in layup style to safe time building a mold Stock 9kg My optimized one before was 2kg and my new 100%cf will be around500-800g

    Some news Fuel tank is mounted in, with maximal weight reduction fiberglass floor around it ( fiberglass because its temporary, later will the engine come there as you know ) It needed just an additional 200g alloy strut to mount it Perfect Now I need to fill up gas trough the trunk ^^' I'm now finishing the carbon fiber floor in front, 1.3kg each side. so unbeleavable light. You have to totally reconfigure your brain when you hold this crazy light and crazy stable floor in hand the ultra Epoxy glue of death is ordered to fit this in hopefully I save enough weight for this effort ^^' Now with this parts done, I made the brake through to build very strong structural parts I decided to try fabricating the two steel struts on the lower end of the car from carbon fiber Here some pictures

    I have it since a year but not installed XD I will install them this spring

    I love that exhaust looks brilliant when you say wishbones, do you mean just the rubber bushings? In this case maybe powerflex would be the right for you, they also have Lifelong guarantie

    Thank you for that link

    Thank you! I will reduce all possible weight. Going for less weight than a 4c! I bought now a TIG welder, so I can weld billet alloy stuff and replace even more heavy parts Also I can weld my insane water intercooler. Thats right, but I don't wanted small turbos wich come on their limit at 6k. I drive my engines hard to the limit and later the limiter will be at least at 8k The turbo is so big, even on lowboost it showels a ton of air in that engine. Even when I would have just 0.2 Bar on low ends it would be a huge mass of air But anyways with the weight of the Car this engine spools up so fast, I rarly drive it on the lower range on hillclimbs with highpower streetcars allready noone defeated my monster (then it was ~80kg heavier than now) it says its for between 320-850hp, but a friend made with one of these 1000hp on the dyno in his supra Of corse I will approach slowly ^^' (1000kg and 600hp would be power/weight ratio like a bugatti ^^) I think the lower end won't be a problem, I will program it to have more a constant powergain than boost punch makes it more drivable. Ah btw. my additional Idea is to make a boost bootle, in which I send the compressed Blowoff air. Either then by boost button or on lower boost recycleable. But thats very far in the future. ^^' Thank you

    Tripple post, but some news I've cutted out a ton of sheet metal. Also de Fiberglass floor is done ( needs some grinding and painting) Up next is pressuretesting the new Tank Welding a Strut in the back build the carbon foot floor in front put all back together It will be incredibly loud in there :S Oh btw. for my rear engine build I finally recieved the Turbo power up to 1000hp, but of course I start not with full boost, but when we want to build something street legal here (just 20% power increase is affordable) they test it and write down the part numbers but one day I hope to get 3 digit HP on the rear wheels of my gtv would be fun 1000kg 1000hp ^^

    Hi all Big disillusionment, I cut out the fuel tank. Then messured it. Without gas it schould be around 21 KGs. Thought it would be alot more. :'( The new 60l alloy fueltank (60l is needed for longer trips f.E. to track or mountain, when I race it I just fill it as much as needed) is 7KG also including fuelpump and foam. But of course to save as much weight as possible I cut out the whole floor behind the seats and replace it with fiberglass (not carbon fiber because this will be replaced soon with the rear engine swap) After the tank mod, the floor under the seats will be replaced with carbon fiber And when my big oven gets delivered I build a new ultralight carbon dashboard

    Beautiful Pictures!
  10. Carbon Fiber Engine Sidepanel

    Thank you! Yes I know they are quite expensive. But even if theyre just decor parts its a ton of work and big cots for big oven. The market is too small to produce in mass. But I made those anyway just because I wanted them for myself
  11. Carbon Fiber Engine Sidepanel

    I've made a cool product. for my car I did a ultrathin version which saved me 1kg in total Full Carbon fiber part with a PU Glossy finish https://roellin-racing-shop.ch/produkt/gtv-spider-abdeckungen-carbon/

    I use the car for sporty drives in the alps and track. Sometimes I daily drive it It was 109 pounds, but unfortunately it was a very cold day when I tested it, to cold for this smal battery to start the big v6. It failed :'( But anyways I read a lot about lithium batterys since I have one. I am glad that the lithium battery didn't work so I dont have to install it XD My old battery is ~5kg also not that much and absolute daily usable. but what I will do is at least mount the battery in the drivers footrom, so I can save at least 500g-1kg . Btw. the battery I use now is: https://www.demon-tweeks.com/eu/odyssey-extreme-racing-18-battery-pc535-odypc535/
  13. Alfa GTV CARBONara

    hihi I am glad to hear that you like my project I've recieved my new Lithium Battery this is 0.5kg Compared to the ultralight 5kg Battery before absolute brutal XD I think it should be enough cranking power with 140A, but I will see later today When this works I will cut the long and haevy Battery cable (the one through the whole car ) and put it in the passenger footroom I'am not 100% shure if a lithium battery is really suitable with the stock alternator and so on, but we will see^^' at least it saves 5kg for very low cost XD
  14. Alfa GTV CARBONara

    I have now freed the new rear axle for my gtv Its now alot easier to work on it and reduce it to whats needed.
  15. Alfa GTV CARBONara

    shurly also because it has the best cw value of them with around the same power (aerodynamic coeffizient) We will see if I can smash the gearbox not the first thing which is going to brake ^^' q4 would of course be fun, but I think does not match to the sporty agily GTV. AWD is for me more a rally thing, where its really needed
  16. Alfa GTV CARBONara

    yes, my insane plan: I saw the bimotore guy from Netherland. Which has an engine in the back of his gtv. And I thought why not just one engine with big turbo in the back. For maximum performance and traction over 350hp In the video he said that he used a 166 subframe reverse to mount the engine in the back. To make life easier I bought an 166 cuted in half and startet planing to do it the same way. I have allready written with the builder of the bimotore and earned some details to the build. Will be alot of fun, no space problem for my huge turbo
  17. Alfa GTV CARBONara

    from what I heard the GTA Gearbox is longer (more highspeed) than the 3l and also stronger. 3l gearboxes I have 2 laying around. But I read once on the internet, the 3l has its limit from material at 280kmh. We will see I am happy when I get all to work and run ^^' its a ton of work I can switch and upgrade all later when its together, but next season I drive it still FWD. It has enough prework for rwd. in the next days, I do the alloy tank mod. this will get crazy weightsavings and frees allready the stuff for the later rear engine Here a Picture from the rear engine Project. Turbo manifold was almost done, but now I have the other big hp engine which I think I use. I am still reducing the half 166 to the minimum needed. But for this project I take enough time. As its the most extreme undone mod, I need to enjoy it Its easy, but alot of work.
  18. Alfa GTV CARBONara

    You will see the carbon when the hood is closed Just the blub with a little chrome and the "xenon'ish" ball will look stock. (I attached a picture) I need to build the glass different than initially thought. I wanted to mould it with epoxy, but its too viscous, would need a ton of layers and will probably brake while unmoulding it. So next try is to do it with acryl glass. But this is ok, never done this before btw. the carbon part is 50g compared to stock 101g. The glass wil be interesting Btw. my 60l Alloy fueltank arrived on saturday. this will be the next step on this GTV, but at the moment I have to much projects startet^^' I have also bought a GTV from a friend which has a 3l 12v TB engine with forgend pistons and 500hp (unfortunately stock rods :S ). Not running for 3 years. This I will bring back to life and when the engine is as good as told, I will put this in my project This also has a Q2 and GTA Gearbox. But I am not shure for now, how I will do it. maybe forged Internals on the 24v would be better, but of course more expensive. I don't know yet, we will see
  19. Alfa GTV CARBONara

    Headlight weight reduction. Original weight 2.3kg lets see whats possible I am also moulding new glasses they are 530g should be possible to build with max 100g I think
  20. Alfa GTV CARBONara

    sorry for multipost, but impressive news: my carbonplenum is just 200g, saves 3kg to oem one (Still raw on the picture, is getting grinded now)
  21. Alfa GTV CARBONara

    a detailshot
  22. Alfa GTV CARBONara

    I have bought the one from ACT, but for legal reasons I didn't mount it till yet because of the carbonfiber they easily see that its modified^^' These ACT are to pretty to paint. I didn't want to show it first because I need do buy more clamps first^^' I have made a CarbonCopy of the ACT Actually I tried to optimize the actual ACT f.E. by grinding it on the inside as smooth as it gets out of the mould on the outside I also "removed" on mine the trompets, but I've formed the inside like trumpets. (I am actually not shure if the trumpets are just for easyer manufacturing or if the actually bring a benefit in there) Further I added gold heat reflect tape on the underside and my Plenum is actually felt lighter than the throttlebody For a first try it am very happy with the outcome, but at one little spot I grinded to much. when I throw it on for testdrive it gave a hole. I have made a pressure test with my compressor before, but it didn't work so well holding all the holes closed^^' I need to improve that next time. I will build a new much stronger one the next days for my N/A engine. For my turbobuild I build an insane bulletprove kevlar one Thx

    some candy for your eyes bolted down of course with polyamid screws (~0.2g insted of 4g)
  24. Alfa GTV CARBONara

    was so clear that this will come but I don't want the engine to be so dirty. Dirt is weight and dirt damages electronics :S Because of the height of the car and the insane wide wheels I allready have a very reduced wheel well I think I will not produce this for the mass. It would get too expensive to produce a mould and dry and harden the carbon in a temperated vacuum. I could produce a set for 550CHF, but I allready know Is too much for carbon covers on the international market. On the domestic there are just very few possible customers with a GTV. But with this knowledge, I am focussing my shop now more on the domestic trackday and tuning scene than on Alfisti as on the beginning. (My copy I produced ultrathin, I used the original part as mould. With this method its around 0.5-1mm thicker than original, which doesn't really matter to me regarding the lower material costs. But this is more work as I need to grind the surface flat and smooth, so no alternative for mass production using a negative mould.) Btw. I bought a GTV with a 3l 12v Turbo with insane internal mods incl. forged internals, running allready on insane 1.7Bar boost I will now upgrade this engine and throw it in the trunk of my GTV (after a ton of other stuff I will do first)
  25. Alfa GTV CARBONara

    yes those.
