David, my hat is off to you for retaining points and originality in your car. I too believe in originality, but was fed up of trying to sync and tune the points. If you can pull it off successfully, congrats! | ||

Electromotive is in my town! They are one of my customers! I've met the owner and been a guest in his home. I never thought to check with them to see what they offer for the 348. | ||

Here is the story on the poor little 308. It is due for the 15,000 mile service. The dyno test merely confirmed what the seat of my pants suspected. Considering that it had such low mileage when I bought it, I doubt it has ever been tuned. Wires look in good shape so they may have been replaced at some time. Cap and rotor appear to be OK. I am currently starting to check out the points to see their condition although my inclination is to just replace them and make sure they are gapped correctly. Then I will check the ignition timing. I suspect that it is seriously retarded because I can tromp the throttle in a higher gear up a hill and I don't get pinging. I bought the car because it is bone stock and I am going to try to keep it that way. Therefore I will go with points etc. I know the electronic ignition/tubi crowd will tell me to get with it, but my first objective is to get this car running up to it's stock potential. I should also note that I haven't done any of this kind of work on a 308 before so I am moving rather deliberately. If anyone has kind words of advice on this subject, I will be pleased to listen. Thank you. I look forward to posting the improved dyno results once I get this car cookin' | ||

John, Are you running a map sensor (vacuum advance)unit with the Electromotive and what are your settings for advance (initial, 3000, 8000)? | ||

Here are (most) of the dyno graphs from the Seattle event. I'm the guy with the jet issues and Electromotive installation. The former is annoying but I'm pretty confident I can sort it all out and get strong performance throughout the RPM range. The latter... ROCKS. It's not a particularly cheap or trivial modification, but the Electromotive system sold by Nick's shop is a very well-built piece of hardware. It's worth it just for the ability to define your timing advance curve with three separate trimpots. I fully expect excellent reliability from this system, and it should by no means be blamed for the fact that I only pulled 178 RWHP at the dyno event.  | ||

Henry, the car that had the direct fire Electromotive Ignition was the 1976 308 with the 175 horse rating. The owner said he's tested before at 195 horse with bigger main jets, but the smaller main jets are better suited for driving around a lower rpms.... He wishes there were a jet size more in the middle. Gary | ||

I have an 83qv with a borla on it. I would be curious to see what it puts out to the rear wheels. It seems to run strong but since I havn't driven many other 308s I can't really say. | ||

I haven't set the day yet, but would early April work for the Dallas folks? I think it would be on a Saturday. | ||

Thanks for the info. Do you have the rear wheel torque figures? Kevin | ||

I think the 77' must have still had points right? The ignition may not be setup properly especially if it is stock and hasn't been looked at recently. | ||

Only putting 178 hp to the rear wheels? With a 20% loss through the drivetrain, you are putting @ 215 hp to the flywheel. That's not too far off factory quoted numbers, which is pretty good for a 25 yr old car. However, the '77 at 137hp is definitely in need of some refreshing. | ||

I have listened to a few comments from 308 owners stating that their 308 was slow, and they wanted to know what to do to get more power, or if they should trade up to a faster car... As in most cases the owners have never driven a 308 that was running in top shape, and just assumed that their car's performance was it. Well, it sounds like most of the 308's need a good rebuild... The 77 on this list which is owned by David S. is giving up a good 63HP to Gary's QV. Case in point, my 77 308 which is in need of valve guides and a good freshen up is only putting 178.2HP to the wheels. Lets face it, most of the older 308 series cars have either been parked, or driven. If the previous owners of my 308 drove it anything like I drive it today, it's had a very exciting life. It also has a list of things that need attention. Suspension bushings, steering rack, pads & rotors which have been purchased already but yet to be installed, before I even attempt to start the engine tear down and rebuild. Which should after all modifications give me 115 more HP. that would put rear wheel HP at 293HP, which should be enough to keep up with the 355 on the list with 289 at the wheels, and eat most 328/348 series cars. But alas, my wife has a list of projects which I must finish before I can go play with the car, as she puts it. Our house is on the historic district's spring tour of homes this year, and I have a boat load of things to do before april 20th and 21st. Then I can go out and play... | ||

You know they are at the rear wheels. Now if they were all engine outs, then it would have been a cam belt day instead, or even a valve job day, especially for the 1977 308.........lowest. You know it could just be bad carbs, what do you guys think? | ||

Those are probably Dynojet rear wheel figures. When I had my '84 308 QV, it dyno'd at 191 hp. | ||

Interesting results. Is this at the flywheel or rear wheels? That 1977 with 137 HP sounds like it needs some going over huh! The 308's seem low in general except for the 83 QV. What do you 308 guys think of these numbers? | ||

Hey Gary, Which 308 had the electromotive ignition? Did any of the other cars have any significant modifications? Thanks Henry | ||
