this is just a general question that i was pondering so i thought i might ask it here in advanced to get a more technical answer. the question may sound simple but i'm sure it is open to debate and is actually pretty technical.

my question is...why do inline 6 cylinder engines seem to be able to produce more power than a V-6 engine? i know this isn't related to our DSMs but i was just curious. thanks.

Well one reason has to do with harmonics. An Inline 6 is naturally balanced as a opposed to the V6. Therefor an Inline motor is able to make smoother power and able to make better high end power because it is not hampered by the same amount of harmonics (Works as Friction)at high RPMs as the V motor.
V motors are smaller and more compact (shorter) and are easier on manufacturers to stuff in small engine bays.

Does not belong in Advanced... moving to Gen. Tech.

Walk N U is exactly right. I think the only downfall I hear on inline 6's is that the crankshaft's have to be VERY strong b/c of their length when pushing big power.

Like :hail: Supras and Skylines. Hail to the Inline 6'ers

dont forget the Bimmers

along the line of strong cranks i wonder about that bugatti w16 cylinder coming out thas a big crank

bugattis original quad turbo W18 was a much more beautiful engine before VW/audi bought them and ditched it for thier quad turbo VR6 style W16.

an I6 doesn;t need any extra harmonic balancing like a V6 does. plus it has 3 more crank bearings then a V6 to keep it in place @ higher revs.

the only problem with an I6 is they only come RWD*, and since most manufacturers don't build RWD's now, theres really no nead to build an I6 even though it is a far superior engine then a V6.

* vovlo does make a fwd horizontally opposed I6, but theres virtually no room in the engine bay.

An I-6 is not necessarily better than a V-6. Compare a 3000GT VR-4 and Supra TT STOCK for STOCK.

The engines have the same displacement, one is a V-6, the other an I-6. They both put out the same HP (at least pretty damn close) and the I-6 has turbos that are the size of a turbo upgrade on the V-6.

Why does the V-6 have smaller turbos and still put out the same power?

That doesn't sound superior to me. However, under high HP applications the I-6 is a much better engine because of the engine's balance.

Who are you arguing with? We never said anything about supra's Vs VR-4s.

Well, if you read what he actually was talking about, he was comparing them because supras are inline 6, and VR-4s are V6. Anywho, I think that BMW has the best inline 6 in it's new M3. Damn, so much power from a naturally asperated 6 cylinder.

"my question is...why do inline 6 cylinder engines seem to be able to produce more power than a V-6 engine? i know this isn't related to our DSMs but i was just curious. thanks."

...was the original posters statement. I never heard anyone make an arugment as to why the VR-4 is faster than the Supra. He asked why inline 6s were better than V6 engines.

can someone please answer the question even though it doesn't realate to the original question. why does teh vr-4 make the same power as the supra tt? is is because of the amount of boost both cars are pushing?

plus it has 3 more crank bearings then a V6 to keep it in place @ higher revs.

I was think about how an I6 has more main bearings, wouldn't this mean frictional loses? i.e., an I6 would have more crank friction...

I understand how an I6 would have have better balance, but does that = more power?

My first experience with an i6 was with a ford pickup. I noted the same thing... I was weired out becuase I noticed the thing seemed to have more power than the v8 trucks we used, and seemed much smooter. So I have to agree, what is it with i6s???

He was using the VR-4 and Supra as examples to show that inline 6s don't necessarily have more power than V-6s. When engaging in a discussion it is often prudent to use examples to prove your point.

Anywho, Nomiezvr4, it does have to do a little with the boost. It also has to do with bore and stroke of the engine and such.

there are MANY variables that ultimately result in a car's power output. similiar displacement and turbos is hardly a close comparison.

Why does the VR-4 and Supra have the same HP rating at the crank? Well, because that's the specs that the manufacture's put out for these cars. No other reason. Why's the sky blue? It is.

Well, I haven't seen anyone mention the Buick Turbo V-6 of the GNX. Now, that's some serious V-6 Ass-whooping. I drove a 80's 7-Series BMW on the Autobahn at 155-160mph for over an hour straight with no problems, except for my knuckles getting tired. I would say the answer to your question lies with design and engineering. I am of the opion that the straigt 6-s have more potential for higher HP applications. Maybe, I am biased. I have never really cared much for V-6's. I would say that the displacement of the majority of the Straight 6's is greater than that of the V-6's. I don't recall seeing alot of V-6's with a displacement higher than 3.8L's. I do recall seeing lots of In-Line 6's with high 4.XL's displacement. Peace...JIM

4.0 V6 in my explorer. As far as I know they still use them in explorers. 4.3 used to be used in the little Blazers and Jimmy's. "It's not size that's matters"
