about lighthening..
i agree.. :)
after taking off the carpet and rear seat,
my car really feel very loud inside......

maybe there are more to strip.. like the door panel, etc etc...

theoratically, i feel that lighther car will accelerate faster,
and stop faster.


Yeah a lighter car will accelerate and stop faster. I remember reading somewhere that taking 100lbs off the car is the same as adding like 10 horsepower or something like that. I think what Mawler is trying to say is that just stripping interior pieces won't do much. To really feel a difference you would probably have to go the whole nine yards - strip interior, remove sound deadening, lightweight bucket seats, remove most/all the dashboard and use fibreglass fenders, hood, trunk etc. That's what you'd do with a race car but if this is for a road car it's a little extreme IMO.

The (original) defect had a hotdog under the passenger seat too - it was about 75Db inside

I drove it without the hotdog muffler once(straight through system) my ears ached for hours afterward

planning some kind of sound deadening with The Defect III as I like my hearing

The Iron Maiden (black car) has that hotdog now and is relatively quiet - but apart from no carpet it's has a full interior

as for doortrims - don't bother about removing them the weight loss is not worth it...

with proper tuning, exhaust, intake
and a better carburetor,
i can gain about 15horse at flywheel..?
More like 7 or 8 hp. You will feel it when you rev the engine up to 4,000 -5,000 rpm. If you drive between 2,000-3,000 it may sound louder, but won't be any faster. The larger carb mainly helps at high RPM.

Spot on, a "HOTDOG" is just a straight through muffler that is shaped like a HOTDOG. Some people also call em resisators as well.

I think its a bit pointless to worry about peak hp figures for an old pushrod n/a 4cyl, as the dyno print will not impress anyone. whats more important is that the basic tuning and breathing mods will make the cars engine more throaty and willing to rev, so more fun to drive.
if u dont want to rebuild the engine because its in good condition already, then using good friction modifying additives like slick 50 or Nulon i find always gives about 5% more power and economy, as well as smoother and cooler running. plus extending the life of the engine.

yeah... 'lively'.. that is the word i wanted to use.
Any tuning tips for our old engine to rev more freely?

btw, "friction modifying additives " = engine oil additives?


thanks

Not something I am very fond of. Rather use a good quality engine oil or full synthetic.
