So why a 5 Cylider? is there anything special about 5? why not 4? Until now a ton of my friends didnt think a 5 cyl existed. When I first mentioned my car, they laughed at me and said I was wrong, until I showed them.

Unlike me these guys are into the whole circuit and drift racing, one guy owns a 2001 Honda Prelude and another an 87 RX-7. These guys know there shit about cars yet they didnt even know about the 5 cyl?

can someone explain if there is anything special about the 5 cyl and why its sideways?

Yeah Volvo makes a lot of 5 cylinder engines...or used to at least. I know my cousins 2002 C70 is a 5 cylinder...pretty funny shit when he tells people and they're like " No way! Your car can't be a 5 cylinder" haha

^Yeah I see listings on craigslist all the time people saying Acura 2.5 TL V6!!! You don't even know what the hell you are driving???

levelfamily

I don't know what's really going on with the 5 cylinder but in my opinion is gotta be one of the best car or worst, because acura co. never made it again. so what's up with it. ??

when you talk talk to people that really know about car > "that's what are they think"<<you said i got a acura v5 they laugh at you then when you show the car the got shock oh shit what the fuck is this car.

An inline 5 cylinder engine produces more torque than a 4 cylinder. The car is far too heavy for a 4 cylinder engine unless it's turbo (which would have never happened in the mid 90's). Volvo in fact does make a ton of 5 cylinder engines, some of which are turbo. They have been making them for a long time and still are.

If you take a look at the reliability of the inline 5 in these TL's, it's well above average. I have seen some seriously high mileage 5 cylinder TL's

The engine is actually set up like a RWD car (being "sideways")

I always enjoyed telling people I had a 5 cylinder. It makes the car pretty special.

Ask him how many "cylinders" his Rex has, .

Correction: Never would've happened to a US-bound Honda.

I remember in about 1997 or 1998 when Acura actually marketed the 2.5 TL as the 'sportier' version of the TL lineup.

It always seemed to me to be an odd duck as to why Acura sold the 5 cylinder TL right alongside the 6 cylinder version. When I test drove both back in '96 there was no comparison in terms of low end torque and the the 3.2 was the clear winner.

Baker831

Your right about the reliability of the car. Mine has over 212k miles and other than tune ups, I haven't had to replace major parts. I'm am due for a new tranny within the next year.

bigwerm187

yeah i made money of that..lol... my friends didnt belive me and i bet them 100 bucks that i had a 5. and welll yeah got myself a full tank of gas and so grub..lol...

Baker831

Ive taken advantage of the situation as well.

kyokushin

Don't forget one of the greatest rally cars ever made, the legendary Audi Quattro, had an inline-5 cylinder engine

bigwerm187

^^^^^ o yeah i herd bout that but ive never seen that motor

Mr_Outside

When people see that I have a V5 they crowd around taking pics. The ones that believe me anyway.

There is a legend (may be half-true) if you look to the G engine (in japan's cars was two of them G20 and G25) you'll see that cylinder have real inclination from pintle.



Some of real hardcore G-maniacs belive, that this is half-part of honda V10 formula 1 engine Somthing like this:

Actually the 2.5 is an inline 5cyl. so the 'V' terminology would not apply. Would be interesting to see the engineering needed to balance an odd number of cylinders in a V configuration, ie. realllllly hard.

bigwerm187

hahaha smae here i told them am start to charge them for takeing pic of my motor..llol

so what car was this out of..??????

Ken1997TL

So who here has driven the G25 (5 cylinder) engine with a manual transmission (in other words the Acura Vigor) ?

If you haven't, find one and do it. You'll understand why they were made. You'll instead try to understand why no one appreciated them and Honda didnt built more of them.

Go90go

An F1 car.

bigwerm187

and that other one with the carbonfiber cover..? what motor was that car off...?

bigwerm187

like what do u mean..? the car drove crapy or what...? i didnt know that they came in stick...

andrew070489

^^ the vigor was a model before the TL was introduced.. it had the in-line 5 and came with either a 5spd manual or 4spd auto..

bigwerm187

^^ yeah i new that but i never new that tthey came in a 5spd tho... thats crazy..

andrew070489

^^ yupp.. my tranny is starting to go at 194k ive been entertaining the idea of a 5spd conversion but its like 2 g's more, auto it is for me :-(

5cylinder

You asked quite a lofty question but here is an introduction.

The 5 cylinder was conceived to have the power of a v-6 with the fuel efficiency of an I-4. Results vary.

The motors have been around for a long time and have shown to be strong motors, seen in volvos, Volkswagens, even mercedes. The new Hummer H3 is an inline 5, there is a euro market ford focus with the same motor as the volvo C30, A very solid motor.

The following is from wikipedia (sorry) but from an engineering perspective it shows the mechanical advantages and disadvantages in an inline 5 design.

The 5-cylinder engine's advantage over a comparable 4-cylinder engine is best understood by considering power strokes and their frequency. A 4-cycle engine fires all its cylinders every 720 degrees — the crankshaft makes two complete rotations. If we assume an even firing engine, we can divide 720 degrees by the number of cylinders to determine how often a power stroke occurs. 720 degrees ÷ 4 = 180 degrees, so a 4-cylinder engine gets a power stroke every 180 degrees. A V8 engine gets a power stroke every 90 degrees, (720° ÷ 8 = 90°).

A given power stroke can last no more than 180 degrees of crankshaft rotation, so the power strokes of a 4-cylinder engine are sequential, with no overlap. At the end of one cylinder's power stroke another cylinder fires.

In a 1-, 2-, or 3-cylinder engine there are times when no power stroke is occurring. In a 3-cylinder engine a power stroke occurs every 240 degrees, (720° ÷ 3 = 240°). Since a power stroke cannot last longer than 180 degrees, this means that a 3-cylinder engine has 60 degrees of "silence" when no power stroke takes place.

A 5-cylinder engine gets a power stroke every 144 degrees (720° ÷ 5 = 144°). Since each power stroke lasts 180 degrees, this means that a power stroke is always in effect. Because of uneven levels of torque during the expansion strokes divided among the 5 cylinders, there is increased secondary-order vibrations. At higher engine speeds, there is an uneven third-order vibration from the crankshaft which occurs every 144 degrees. Because the power strokes have some overlap, a 5-cylinder engine may run more smoothly than a non-overlapping 4-cylinder engine, but only at limited mid-range speeds where second and third-order vibrations are lower.

Every cylinder added beyond five increases the overlap of firing strokes and makes for less primary order vibration. An inline-6 gets a power stroke every 120 degrees. So there is more overlap (180° - 120° = 60°) than in a 5-cylinder engine (180° - 144° = 36°). However, this increase in smoothness of a 6-cylinder engine over a 5-cylinder engine is not as pronounced as that of a 5-cylinder engine over a 4-cylinder engine. The inline-5 loses less power to friction as compared to an inline-6. It also uses fewer parts, and it is physically shorter, so it requires less room in the engine bay, allowing for transverse mounting.

A 5-cylinder engine is longer and more expensive to manufacture than a comparable 4-cylinder engine, but some manufacturers feel these costs are outweighed by its greater capacity in a smaller space than a 6-cylinder.

From the standpoint of driving experience, 5-cylinder engines are noted for combining the best aspects of four and six cylinder engines. They generate more power and torque than four cylinder engines, while maintaining the fuel economy and "pep" of smaller four cylinder engines. Five cylinder turbos have been used on more than one occasion in sport and racing applications for their balance of performance qualities. The Volvo S60 R (racing edition) has a 2.5 liter turbocharged inline 5-cylinder engine which is capable of generating 300 bhp and 295 lb-ft of torque across a large amount of its RPM ranges.

A disadvantage of a straight-5 over a straight-6 is that a straight-5 engine is not inherently balanced. A straight-5 design has free moments (vibrations) of the first and second order, while a straight-6 has zero free moments. This means that no additional balance shafts are needed in a straight-6. By comparison a straight-4 has no free moments of the first or second order, but it does have a large free force of the second order which contributes to the vibration found in unbalanced straight-4 designs.

[QUOTE=5cylinder;10281523]You asked quite a lofty question but here is an introduction.

And in the case of the 2.5TL the results vary a lot from the concept as my CL-S6 makes way more HP/torque and gets better gas mileage than my TL.
Still, I am appreciating the balance of the 2.5TL engine/chassis more after some near scary experiances w/ getting on the CL-S in bumpy and/or wet corners. I'm thinking too much torque and so torque steer in a FF car is not a good thing. I don't think I ever had to fight the steering wheel in the TL and it is a smooth ride.

Ken1997TL

[QUOTE=monkeybutt;10283932]You also have an extra two gears with an engine that has lower friction and less rotating mass. More power and better gas mileage.

I sawp my UA2 a\t to vigs m\t. Thats awesome, you right. But IDs of japaneese and us m\t's are different. S7MX in Japan and LA3A in US - may be stuff is different too.

Ken1997TL

I think the gear ratios are different too
