as I mentioned earlier here on my engine there is a "LENZ TURBOTRONIC". this manufacturer is not existing anymore here in germany but I need urgently some infos about this system on my car. even koenig could not tell me. so I looked around in the internet and I found a homepage of lenz in USA: Lenz Motorentechnik USA manufacturers of Formula 1 based engine management systems - USA Home on this page there are some partners of lenz, but those here in germany I alreday contacted and they could not help me. also I mailed OG racing in sterling, virginia, without getting an answer. so perhaps someone knows this OG racing or lives near? to send a mail to lenzmotorentechnik there is a mail address: John Desmond, eMail: [email protected] I send already 3 mails also without getting an answer. so may be one of you all here could help me to get in contact? or does someone knows about this turbotronic?
one problem solved the next problem coming up after long time working on my TR koenig competition I was driving 2 days ago first time again, testing all my sensors and nearly all was fine. but the turbopower - WOW- long time ago I had this feeling. at about 150 km/h in 4th gear the rear wheels spinning. incredible ! ! ! so yesterday in the afternoon and the half night I washed the car, polished it, cleaning windows and so on and today I wanted to make the first longer test drive. all was fine. first a little warm up, then on the autobahn, speed about 320 km/h, too much traffic, then on the normal road back at home, some uphill, and suddenly, at about 130 km/h during acceleration the engine was rewing but no forward drive anymore. soon I thaught about broken shaft from the primary gearbox to the maingearbox. during waiting for the towing truck I thought: engine out - gearbox dismanteling again and so on. 1 hour later in my garage I was surprised, positive surprised, even the shaft is broken as I thought, but not at that place where it normaly break apart. no, it was broken in the back as you see on the pictures. so not such a big deal problem is now this shaft. this one here that was broken was the only stronger one I had here. but not strong enaugh as you see. from the original I have two more, but those I will not take. specialists know why not a while ago I was reading here in this forum from someone how made stronger ones or even have some in stock. but I can not find after short looking. can anybody help? have a nice weekend all Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
I bought a shaft from Robert Hayden on this forum...It's supposedly some special twisty alloy with a ton of memory...That's what I'm using on my twin turbo project
Dear Ferraristi, Here ya goooooo....... http://www.ferrarichat.com/forum/members/39094.html Robert's a cool guy and knows what he's talking about. Shamile Freeze....Miami Vice!
Sorry to hear that but you DONT want a stronger shaft The shaft acts like a fuse that protects the trans. If you install a stronger shaft the next weak piece will break and that will be in the trans and it will be a lot worse & a lot more $ than a broken shaft. unless you are prepared tyo throw down $50,000 US + for a full race trans just keep a nice supply of shafts around & dont be too greedy w the throttle
thank you shamile for this info. first I will look in my area here. we also have some specialist doing parts for porsche and BMW. but I will also contact robert of course thank you for your explanation because of this shaft is like a fuse. this is really right ! ! ! this with several shafts in stock I want to do because it is not even 2,5 hours to replace this FUSE" important for me has been to know that this "fuse" is broken where I wanted it to brake and not inside the gearbox but I have my gearbox ( so the inside parts ) completly made of other material, so better material for the incoming shaft, then the CP made of special material, also the single gears are special made except the 1st set and the reverse. I have not payed those 50k, but also a lot of money I let this now broken shaft made as a fuse and it was broken so as I wanted it. but to early with a boost of about 20 psi this shaft has to be strong enough ( I think so ), because the rear wheels at full acceleration always spinning. so just as it is now I would say that the car is not driveable. when the turbos make boost it is then not like a rocket, it is more like a catapult. you are not able to shift so fast as the rpm going up just now I only wanted to test all my sensors if they are working fine. and that was successful next step now is to put on a map controlled injection-ignitiion system. here in germany we have a specialist that make such ECU´s, it is called TRIJEKT and I still have 2 ECU´s here. works a bit like a motec. but the description is in german and that is for me a big advantage. also I can call them every time and they help me. I got those ECU´s about 3 years ago and I have steady contact with them. then I want to have the full boost not suddenly at about 3600 rpm. I want to start with the increasing boost at about 3200 rpm with max. 7 psi, and the higher the rpm the more boost then, but not as it is now so suddenly. because so as it is now you only can accelerate when it goes straight on. never accelerate in corners . otherwise you may make a 180 ° and more turn that will be THE problem
Also if you are spinning the tires aka breaking traction that puts a lot of stress on the shaft Talk to an engineer about a custom trans but get the big checkbook out. Probably better to forget Ferrari parts & go straight to full race bits. Ive had one case where the trans case shattered
does anybody have pictures from original propeller shafts that are broken? I need urgently pictures of those. so please post them here or ask me fo my mail that you may send to my mail then. thank you ! ! !
none has a picture of an original propeller shaft that is broken ??? so those shafts are so good that they never brake hard to believe
I like to make me a reserve turbo charged engine even the old one is running fine without problems. so I´m looking for 2 used payable valve covers. those are just now the main missing parts for a second engine. does anyone has those? if older style or newer style I don´t care because after I will find those I have then to look for the cam shaft covers. also I´m looking for the 2 camshaftbelt covers. and still none has a broken shaft or picture of broken shaft? I got meanwhile 1 shaft from australia. thanks to TIMEMACHINE and SHAMILE for the contact address data of robert. he is a realy right F specialist. who also until now has a shaft from him and what are the experiences?
Look up SPORTMONZA or call Bill Pollard at Sport Auto in Gaylordsville CT 8603501515 He had at least 1 of my snapped shafts I never took a photo of it
Two old photo's ... most probably from this Forum Image Unavailable, Please Login Image Unavailable, Please Login
Holy shards Batman! That's completely different than the one I'd seen previously, the one "sheared" with a clean break. You can almost see the twisting forces that exploded that. You guys going for the high HP, good luck. There is that comment from AHudson, that the tranny is next to go. Food for thought.
thanks for those pics. also thanks robert for the other pictures. AFAIK the original 17 mm shafts ( first edition, later they had 19 mm ) are breaking in the inside of the gearbox where the 17mm goes to the larger diameter along with the gearing. so to remove those parts it needs a complete dismantling of the complete garbox. this what I see just now on the broken shafts needs not an engine out. you still can remove the inside shaft from the input gear shaft.
Better breaking a shaft than a differential / tranny ! For that reason I do not believe in thicker shafts ... it's the safety fuse imo ...
right mel, the shaft is only 19 mm now, but very flexible inside, and that is what this gearbox need. but I have a stronger diff in, also stronger input shaft and special outputshaft/crown-pinion and those will be much stronger than the original. so it needs a stronger "fuse", like this shaft ( I hope ! ! ! ) I got from robert. and I hope it will still be a fuse like the other I have broken 4 weeks before in about 3 weeks I get new gears for the clutch down to the gearbox. I can go faster with the same rpm then. also I will reduce the boost a little. the conversion to the trijekt I think I will start after this summer, because I would like to drive a little with this car after so long working on Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
First of all Joe, congratulation for your Koenig Competition, These Koenig Ferraris have aroused in me some interest, that led me to buy and search various articles of these cars. I would like to ask you some questions about these TwinTurbo Testarossa engines and their power. The Competition was born with the 800 HP specification with compressor mixed with a double turbocharged system. The KCE 1000 specification was born with the Evolution around 1990, just turbocharged, but immediately something I never seemed clear about its 1000 HP level. Koenig claims 1000 Nm of torque at 4500 rpm and 1000 HP, but calculation explains me that 1000 HP are not possible with just 1000 Nm of torque. An turbo engine has its peak of torque around mid range, then the torque decrease at high revs...so... What I've always suspected is that Koenig claimed his engines for 1000 HP powerplants but in truth just able of 800-850 HP (even if Koenig tested this engine on the dyno at 1000 hp for long time). I'M SURE YOUR CAR WAS FITTED LATER (2002) WITH A REAL 1000 HP POWERPLANT (with 1150 Nm of torque) being it the last or one of the last Testarossa rebuild by Koenig, but I'm not sure these engines were so strong till the beginning!! (Even the acceleration claimed and tested speak clearly, 0-200 kph times were around 10s and 11s tested, your car seems to be 8.9s able..) I would appreciate your opinion about. Thanks.
hello F40lm, thanks for your gradulation to this car and your thinking. you are right: this engine has never 1000 hp. normaly this engine has around 400 hp as you know. so to get 1000 hp it needs about 1,5 bar overboost with the original pistons. that is about 22,5 psi. I was going with about 20 psi. but there are in special psitons with lower compression. so it needs then more than 22,5 psi to reach those 1000 hp. the electronic ignition and the additional fuel injection is made my lenz. this lenz ecu just now makes problems because of the map sensor, not working right anymore. on this ecu is says 1990. so my car with the higher power output has been modified in 1990 or 1991. but even then it has as I think only those 800 to 850 hp. but even that is ok sure, could be more as I mentioned earlier I like to put in a map-controlled ignition-injection system from the german manufacturer trijekt. with this I think I could get those 1000 hp. but this is a work for next winter. just now I put in the new shaft from australia and other gears for the gearbox from the clutch down to the main-gearbox. this will take about 4 more weeks. and then hopefully I may drive this car until there will break again something the weakest link in a chain will always break why you think in 2002 has been updated something on my car? it is right that in 2001 or 2002 the car was not running right anymore and that has been a problem of the lenz turbotronic. so it was told to me from a mechanic who works on this car at that time. to this man I have already a very good contact and he will visit me soon he told me. but he also thinks this engine has not more than 900 hp. he also thinks that with the trijekt the engine would go much better than with the lenz turbotronic. sure, this lenz turbotronic is more than 25 years old. but the fuel consumption with this turbotronic is just now about 85 ltr on 100 km ( if you go always "full power" ), if I count right it is about 3 miles per gallon ??
Your car was posted for sale on Koenig website with this kind of claim: "rebuilt with latest Koenig technique 2002"... Koenig-Specials - Showroom This is the only thing I know. The better performance claimed than the usual claimed (the 0-200 kph improved by more than 1 or 2 seconds) and claimed higher torque data (150 Nm more than claimed on the official data) "contributed" to my guess.. But I don't know if the advertisment on the website says the truth or not, even if my guess is yes being it on the official website. This led me to think that your car was updated in 2002 with a more modern quality of work to achieve higher power result than the usual one...but, this is just what is thinkable simply reading the advertisment. What I'm up against is an official advertisment that claims something better by 2 seconds than what I read on articles like TOP CAR magazine that seems to say the yellow Evolution "tested" was not able to do a 0-200 kph better than 11.0s with the longer final gearing (a struggled 3.9s in the 0-100 kph then 0-200 kph 7.1s later). Immediately my guess was, these cars has engines with two different power or what? I own also fast cars and I know what means in power to improve a 0-200 kph performance from 11s to 8.9s. This is awesome in its power mystery! The 2nd answer is the gearing ratio. I know there are existing 2 gears ratio. The shorter good for 320 kph and the longer one up to over 350 or 370 kph. All this with the usual 17" wheels size (your car has 19" wheels size, while the 1st Testarossa Turbo just 15" and 16" wheels). Is this correct or I need to know more about? Would be interesting for me to know the transmission and gearbox difference between the one used by Koenig compared the stock one... for example, the difference is the final ratio or simply the gearbox used is completely rebuild with a stronger or longer spec? Thanks.
thank you for this link F40lm have not known this ! ! ! I think this car is mine. but there are no F1 mirrors on, no rollcage, but fire extingusher system. just now i have not been on a scale, but when the car will run again I will go to see the weight. as I have written here before: when accelerating from about 3300 rpm it is not like a rocket, it is more a catapult. you can not shift so fast as the rpm raise. it is like the engine is running in idle, no gear in and you accelerate. same is if you drive in 2nd or 3rd. the rpm raising so fast. incredible ! ! ! with the "primary gear box", so the gears in the clutch housing, I can change the single gears to get an other ratio. I will put in here next some pictures how this work. very simple. about the accelaration: even when you accelerate form 180 km/h the rear wheels are spinning on dry road. really incredible and not driveable. fast I have been driving until now has been about 350 km/h, then the engine was stuttering. first I wonder but then I noticed: the rpm limiter was working. that is why I now put in an other ratio. one time I would like to go on a special track here in germany with more than 400 km/h. my dream koenig made the input shaft with the single gears on with special material. also the 2nd and the 3rd koenig told me was made special for him. but with the same ratio as original. the ratio only changed in the "primary gear box", not in the main gear box.
