haha oh but the automatic transmission version has much faster acceleration and gearshift. Its like the new evo's SST system only way more advanced.


automatics are for loooosers


you mean the Evo SST? its just a preset for the next shift. anyway, I agree, Im not a fan of paddle shifters but they still better than short shifters.


no you ditz, have some humor lol...

Does anyone know who invented the harmonic balancer?

Do horizontally-opposed engines have a need for a harmonic balancer or does it not need one?


dunno who invented it; they don't, though flat 4's are not perfectly balanced like their more numerous flat # brothers.

All engines need a harmonic balancer. Doesnt matter now many cylinders there are. The ignition of the fuel mixture sends a shock to the crank and the crank releases the shock by vibrations. The harmonic balancer is there to dampen and relieve that stress away from the crank. Balancing does not mean it doesnt need a balancer. When you balance an engine you are weight matching the pistons, rods, and wrist pins so they are within 1 gram of each other. Then you would proceed to balance the crank with the new weight matched rods and pistons. Having a balanced engine only eliminates vibrations and stress from the rotating assembly. Having the engine balanced is fine but the torsional stress still remains there and it is not a changeable factor in the engine.

The TC-SST will SHIFT better than you. I guess you're the real loser. :P

Most people cannot shift faster than those "automated manuals" or "clutchless manuals", unless you're an experienced race driver.

So, in the end, a driver CAN shift faster/better than a clutchless manual, as the clutch provides more control than an automated clutch.....

Not true. Cars like the Veyron, which run out 1st gear really fast, would be inefficient in a true manual. There are pro's and con's to each side, I guess for everyday cars some prefer manuals, but in racing applications I could see how cars with shorter gears, or higher power outputs could utilize them.

I'm sorry that I made you all mad but I really can't relate to any imports becuae i have a GTO and theres some stuff that don't relate with V8's. And what i meant was what is the part to have and top of the line..not best performance for everything period..or whats the newest trubo, ecu, tune, tyres, but i can't stop you guys from bashing my face in so, what ever..go GTO !!

What about the Boxter engine? is that a longer lasting engine since it eliminates some stress and keeps the engine balanced with 2 cylinders running horizontal?

Harmonic balancers are purely subjective. Some people say they help, others say that unless you are revving in the higher ranges on a daily basis, you don't need them. Many enthusiasts remove them in order to lighten up the crank pulley and free up more power. While I won't comment on the endurance of an engine based solely on whether it has a harmonic balancer or not, I believe that there are MUCH more important factors in long lasting engines. The engine configuration may affect it minimally, at best, but engine oil is far more important in a long lasting engine.

yeah true. of course if someone wants there engine internals a big heap of metal shavings then put synthetic oil..

Harmonic dampeners are subjective but if what they say is true and they are unnecessary then why do all professional drivers all keep their harmonic dampeners whether it be aftermarket or factory. IT does have truth in. The safety feature it is far out weights the gains of a measly couple hp.

Engine lubrication is important to healthy engine life but i beg to differ that synthetics truly is a cure all. Its all about how you drive the car and the thermal breakdown of the oil. I personally change my oil every 2000 miles and I use only conventional oil. Synthetics are mostly used because its resistance to thermal breakdown is much higher allowing you to run longer between oil changes. I have never noticed much of a difference from switching to synthetics except during cold starts where they have the advantages of being much more consistent.

In my eyes there is no need to switch to synthetics with my oil change regimen.

Are you saying synthetic oil is shitty?

I was talking to TheGoat about that since he said "of course if someone wants there engine internals a big heap of metal shavings then put synthetic oil.." I didn't refresh fast enough.
