You guys need a badge with a flip-flop on it. DO IT! DO IT!
Hi Eric, love this thread, if nly for the engineering challanges (but also for saving a 308..) from an engineering perspective i do have two honest questions; You opt for three motors to a total 227 kw. Why? you do realize that with your battery capacity you wil drain them in 9 minutes using this potential ( and probably ruining your batteries in the process) Why not opt for 1 or two motors? second, your choice of transmission puzzles me as you know the efficientcy will be 85% top. was it not possible to create a direct drive and "shifting" electronically? Im just guessing but would that not we much simplerer, less heavy and more fuel effcient? interested in your thoughts
1st question. Your would be drivng at nearly 200 mph at full throttle to drain the batteries quickly. Assuming avg 50mph (every day driver) we would still e left 80-110 averted range. Not a race car but a functional driver. We plan to double range when technology improves. Q2- we are using existing tech and love having a shifting transmission. We could go direct drive but I love the ability to shift. 3rd gear is ok all day long. The six gate shifter is awesome in the Ferrari. Out top end is well above OEM. We do not plan on using 5th gear but theoretically the top speed is estimated with stock tire diameter dimensions at 7500 rpm 4th its 156mph and 5th hits 200mph which is below the redline motor spec of 8000 rpm for the AC-51's. We could put larger motor in and cut do bathe number by we are designing an Electic Ferrari. There is not a significant gain on power vs weight of a different motor package. There is no 200 kilowatt + solution in a single motor. So we are 2+ motors. Two AM racing motors at 100 KW each with controllers would be $30k. For our production of @225 KW in the power plant its a much more economic solution with awesome presentation! We are experimenting and we hope the belts will create some awesome noise to mimic a great whine. We have never done this and this is our best plan.... Will see how it materializes! Thanks for asking and will keep posting!!!
Seats came back fast and other than a little reconditioning on the under frame (paint and lube) these are ready to go back... Out with the all black and in with the tan/black combo..... Hope that works... Used original seats and foam... Headrests suffered mild heat damage to leather but foam was totally usable..... Sent door panels back for a little more work.... Restoring the original black door pouches.... Black arm rests updates on Tan door panel... a couple weeks to see those photos.... Just submitted T-Top after repairing fiberglass heat damage on underside upholstery panels.... going black w black stripes as it was upon receipt of car... unless anyone has a better idea.... Belt pulleys showed up today.... we have to machine them now to fit the Tri-Motor belt system.... Pictures to come tomorrow. Image Unavailable, Please Login
So we are having fun. Mike wanted to have an EV amateur co-host a monthly show to broaden the EV audience (less tech talk) and make it fun.... Here is our first shot from our Black Friday session in the shop.... totally un-scripted and lightly edited..... Batteries ran out on camera (no pun intended about the EV guy)!! https://www.youtube.com/watch?v=8_yb_nW5x6I&spfreload=10 Please comment! Thanks for having fun with our project!
I'll be in San Diego a couple of times this month. Mind if I drop by and see this build in action? Very impressive and creative project.
Silly question, but - if you're pulling the Ferrari engine, customizing the badging and wheels, etc. and generally going all-out on a unique build, why not switch the louvers in the rear deck lid to some sort of lexan or glass to show off the electric innards? The louvers are there to vent heat built up by a combustion engine and it's stupid heat-trapping cats. I don't imagine you'd have that problem with electric. Just a thought.
Or - alternatively - keep the louvers and swap the metal "bulge" in the center of the "U" for lexan...
I watched the youtube show earlier tonight - very entertaining and fun to watch. I hope the next episode has more Ferrari content! Are you planning to do any high speed runs? Maybe at the dry lakes? And if so, are you concerned about the aerodynamics of the 308 at speeds above 140? I will be in SoCal in January - I NEED to see this thing!! Glen
BOOM, Glen! Lexan cover in place of the metal "bubble," solar "skins" in place of louvers and on the detachable rooftop!!!
Love to hear suggestions and we will learn a lot about things to adjust or consider if or when we perform a second like project. Thanks for the input on the show!! 1. We are always open for shop "stops". Let us know in advance when you want drop in. We will have much more on the Ferrari Project. 90 days have yielded a lot of progress on this 308 build (or should I say de-build??) in preparation for the build. I have been personally driving and working the project labor and management and it is both consuming and and rewarding. I'm grateful for all the help from multiple "Interns", outside vendors, and Mike Breams general and technical guidance. We will be documenting everything we do on the build. 2. We plan to test the 308 GTE side by side with an OEM 308 GT. Happy to take any volunteers with a 78 308. We will suace by side compare on the Dyno, 1/4 mile, track, and about any other test of interest. Of course we will video document all to share. We will compare the weight distribution of all four corners as well and asks if the new coilovers as best we can to accommodate any shifts in weight distribution. Total weight vs curb weight is a close watch on our radar as is the distribution of weight. More as we progress w actual install. Fab on battery box and frame work starts on Weds this week.
As for the cover adjustments we love the OEM nature of both the trunk lid and T top. Likely not worth the trade off for the low benefit of charging. The three AC-51's are air cooled to the venting works well as designed. We do however have some neat ideas for "showcasing" the tri-V motor design! That will have to wait
Well someone had to do it! ) Just makes working on it all that more nostalgic! [ame]http://www.youtube.com/watch?v=XDIiyUZNb24[/ame]
3 items to update of interest: (1) So we re having so much fun, we decided on Black Friday last week to film a 15 minute show and tell for EV West..... I am an EV rookie and try to ask the smart guy(s) EV questions that are understandable in layman's terms. 90 days of a barge of questions yielded the attached which looks like we will do it again.... It is rough but what can we expect for the first unscripted go at it?? https://www.youtube.com/watch?v=8_yb_nW5x6I&spfreload=10 www.evshow.com (2) 308 EV Update! We are headed into the shop tomorrow to mount an AC-50 motor with an EV West flange to the G50 Transmission so we can start the motor installation/fabrication. It is apparently impossible to get time during weekdays!!! Way too much happening at the shop and so much exciting walk in traffic we can not keep up...... We ordered the custom aluminum battery boxes yesterday. Billet Badges in San Marcos is working on cleaning up all the 308 GTS badges... and making a couple "TBA" additions..... The Patrick Motor Sport G50 race shifter kit arrived Friday. Will post pictures of it alongside the original 308 shifter box on Monday. We will have to modify the shifter cable mount trans bracket to fit our shop converted short nose G50....... Picture to follow here too. Note the attached picture of engineering in the dark! Pretty funny that we confirmed the measurements of the SolidWorks drawings in the dark . (3) It is a little known fact that EV West and SRD will be developing, building, and finishing the Baja 1000 next November with the FIRST EVER 100% EV race vehicle. The project is essentially funded, we have logistics framed and the batteries to power the project. It is not required but we will seek sponsorship starting in January. Open to any ideas here (contact me directly via cel phone or pm). We are developing the sponsorship package this month. If it is anything like the EV West record setting Pikes Peak finish in the 1000 HP BMW it will be a real wake up call to racing.... Image Unavailable, Please Login
NFL came in 2nd place this am in favor of setting up the G50 for installation fabrication. We are headed over to Strategic Racing Design in Vista to work with Justin to fab and install the transmission mounts, new trunk liner and frame (to accommodate the G50), the Euro bumper braketts and the 3 battery box mounts. This is the week it starts getting awesome...... Stay tuned for quick fabrication progress!

We would if we could!!! Have you ever looked at its construction? The transaxel is built into the lower engine pan and combined w the oil sump, differential and differential oil pan, and axle connections.... One whole bottom end. I can imagine maintrnance costs asscouated w anybrepair with how tight thenentire engine is built! Wonderful engineering for the 70's! However, Chris Angel would be seriously challenged to make that a part of a new EV build. Would if we could but no way we could figure it out.... And there was a lot of thought on this..... We like maintaining good engineering where possible. We love every part of that car!
This is a better setup anyway as you probably know - and the setup Ferrari eventually went to for future V8s (and the 288 GTO) - longitudinal mounting vs transverse. Should be able to keep things nice and low in there I would assume. The 308 actually isn't that horrible to work on if you have the cover off and the wells out. Of course, major surgery requires removing things. Try working on a modern Audi if you want to see an serviceable car ; )
Good input...... I will look into that for prospective project use! I have to confess we got a screaming deal on the G50 and the PMS shifter kit is going to work really well with it.... and w the original gate shifter set up..... The Tri Motor set up will look really good and fit well with the mid battery packs (and other equipment) in the mid bay using the longitudinal set up. All ears for ideas around here..... Eric
Re: Battery pack location. Why not put where the liquid dinosaur tanks use to be? That is still where Ferrari chooses to put the fuel today on the mid engined V8s. Or, I guess you could try to get them lower since they don't have to be in a single location correct? Lower is better for handling. Keep them in front of the rear axle line of course. Just be aware of how susceptible the rear of the car is to road debris etc. A skid plate is easily fabricated of course. Final thought is that if you do use the former gas tank locations, one could make them serviceable via the wheel wells if that is a concern. Fun project! Good luck!
Another good, low location for batteries would be the front spare tire well. No idea what the limits are in cable run length etc.
24 front and low. 12 each in "L" formation in mid/back frame low, outside of motors, and behind seats. No mods required of body this way. Wheel balance vs spec mfg will be checked for OEM spec when done.... aiming to use good engineering without reinventing the wheel. The car was made to convert!
The build photos are going to show up within a few weeks..... it will answer the questions but we are really happy with what happening! Low center of G.... good weight distribution.... And a little torque.
