Put syncros in it while its out.
The shifting is all fixed now ....with al the engine in/out head gasket nonsense I ended up with no oil in the drop gear case and ruined everything . But that is what straight cut gears would sound like so its racy? Anyway, all that stuff is replaced and there is oil so its quite and shifts nice but that is still the best what not to do with the throttle video I have.
I've had a 308 and 328 for a long time, and loved those cars, and while they were not Powerful like modern Ferrari's they were super fun in the right situation... which is not day to day traffic in Atlanta Ga. .... a 308 with 800HP would be fun.. but not in daily use... or in a city... I just think you would never be able to use it. Its like an F40 - they are fun up to about 4K RPM, and then it gets a bit dodgy... when the Turbos spool up every throttle input is very reactive. On track it would be great. I think there were several 308 SCCA race cars that made about 600 HP and they were a blast to drive.. very fast and stable, but they also had huge tires, and rear suspension was set up with enormous camber. But let me be clear, I'm fascinated with your build, and love what you are doing. If I won the lottery, I'd have a restomod 308 with 400- 500 Hp in a nano second.
That all sounds exactly right and I would add I'm pretty sure a 308 is aerodynamically unstable if it gets over 160-180mph so even on a track there would be issues with lots of hp and the front straight....so yeah, 800hp is too much but I think more on the street than the track, its not the hp its how the engine delivers torque and this very much connects to your F40 comment, steps in the torque curve are very difficult on the street. Also having a decent amount of torque at low rpm makes the car a real pleasure on the street, there is less shifting, no need to be reving all the time, you just roll the throttle in and accelerate, its nice. I did a couple superchargers on the 3.0 V8 before going to the 12 and they were good....the 1st setup made about 360hp and I liked it, but it still seemed not quite enough. The 2nd setup made an honest 500hp and about 400ft-lb torque and that was really nice...mostly. I didn't like the blower whine on either setup but that is tolerable, what mostly bothered me with the 2nd setup was the way the engine felt. A V8 making 400ft-lbs is making 50/cylinder and you could feel each pulse, it would kind of shake and GO! when you push the throttle and to me it honestly felt more like a BB vette than a ferrari. With the NA V12 the pulses are closer together and even though there is more total torque each cylinder is making only 40 and that doesn't happen until 7k rpm, at lower rpm it more like 25 so it feels much smoother and it builds with rpm so it kind of encourages you to let it rev even though you don't need to and it just feels a lot more like a 308, just faster if that makes sense? The side effect of an engine that makes great torque to 7k rpm is hp=tq x rpm / 5252 so it also makes buckets of hp, way more than it needs or could ever use...the hp number is more a bagging rights thing as its not actually useful I think. The comment I've seen most from the guys with 3.4-3.6 308 builds is how the extra torque makes the car nicer to drive so I think that aligns with my experience with my builds over the years. and I think the next step is a not more bore or boost but more cylinders so enter the V12. A 400/400i/412 can probably make 450 or maybe 500hp, as could a well done 4V or 5V 3.6L, but the way the V12 does it I think has much better street manners and more of the feel that makes a 308 so special. Just my thought, not in anyway saying there is a right way to customize a car.
I agree. The 308 / 328 I never had any real complaints when moving, but low down start off torque or highway stuff was the issue. once above 4K it pulled pretty good... but getting there not so much... and when pulling out from a parking lot into a busy street, is when the 308/ 328 felt really anemic. in the 80's that did not matter, but in todays world when a Kia mini van can bear down on you, you need to get going! I've only driven one turbo charged 308 - and it was very nicely done, but again with the F40 analogy when it hit 33oo RPM you wanted to make sure you were pointing dead ahead. I've only driven one F40 - and that was on a track but it was the same thing... if the revs fell below 3500... it felt almost 328 like... but then when the boost popped in... you really had your hands full in a corner.... the owner loved to hang the tail out... I just cringed every time.
I love the power turbos make and for track use its hard to not to want one but for the street I'm a big believer in "there is no replacement for displacement...but a blower comes close". Just personal driving preference, I don't want it to sound like I'm hating on turbos in any way but I love the V12 in the 308 experience.
Obviously can't forget about the contribution gearing (and induction) makes to driveability....I never felt my QV was horribly lacking in low-end torque...and I'm not one to rev the shirt out of a car to get moving. Even when just releasing the clutch at idle and smoothly tipping into the throttle, I had no complaints. It's obviously no big block muscle car (which I grew-up on) or fire-breathing 5.4L V-12, but comparing it to other 200 - 250 horse cars (very few of which can also rev to 8k RPM), I've never felt its low-end response was embarrassingly limp. But who knows, maybe that'll turn out to be my carb car. - Dave
I was going to mention gearing...in my car 1st is about 2nd in a stock 308 which changes the way the engine's torque pulses are felt. As for is a 308 fast enough stock? If you think its fast enough then you're right. If you're not happy then you're also right. Nobody can tell you what you think is fun or funny or whatever so anything I say is just what I think or prefer and in no way makes it 'right" in anyone's mind but my own....but I don't think I've ever heard anyone say "Man! I really wish this car accelerated slower!"....although I guess that is related to something I have heard "Oh my god! please slow down!"
No, totally agree....I wasn't trying to make a "The 308's Perfect the Way It Is" argument, just stating my opinion about its (mine's) stock, off-idle characteristics - keeping in mind what it is and - based on my past experience with other high-torque engines....and I absolutely would not refuse another 150 hp if it wanted to climb into bed with my 308. - Dave
My 308 has to go faster simply because my 1500 Ram will outrun it effortlessly even with a load of firewood in the box. My performance car needs to perform better than a truck
