Ginge !

never heard of em before as such and never new that the scooby wa like it

are they more like a v engine but with more flat design and whats the benifits to em, im guessing they still have the same stroke as a normal engine so its not size i dont think and im guessing they need to be balanced like v engines

what else,,,,,,,, and the scoobys make a sexy noise is has to be said

what other companys use em and why to others avoid em,,,,, any piccys of em stripped ect and how is the sumo set up ect

A designation for an engine where the cylinders are arranged opposite (180° apart) from each other. Boxer engines are relatively flat compared to inline or V-engines. Common examples of boxer engines are the Porsche 911 flat-6, Alfa romeo and the Subaru flat-4,

heres my pic of the flat-4 from the other thread for you

take a lead off then your engine will sound like a Scooby

mine did when I fucked the cam

porka's use em - they are like a Vee - but completely legs akimbo - also called boxers. Only sound good at low rpm's really.

A flat engine or boxer engine or horizontally opposed engine is a type of engine where the pistons lie horizontally opposed, with pairs of cylinders on the left and the right, as opposed to most modern engines where all pistons are inline, or the alternating pistons are positioned in a "V"-angle.

Experts distinguish between V-at-180° engines and real boxer engines (horizontally opposed engines). The horizontally opposed engine has one crank pin per piston while in the V-at-180° engine two pistons share the same crank pin.

The benefit of using an horizontally opposed engine engine versus a V engine is that it provides perfect balance because each piston's movement is exactly counterbalanced by the corresponding piston movement of the opposite side. These engines can run perfectly smooth and free of vibrations with a four-stroke cycle, regardless of number of cylinders, and do not require the counterweights on the crankshaft to balance the weight of the reciprocating parts which are required in other engine configurations.

Automobiles and motorcycles powered by a flat engine generally have a lower center of gravity, giving better stability and control. However, these engines are also wider than normal engines and are more expensive to build than traditional engines and, thus, are not widely used by automobile manufacturers.

Subaru, on the other hand, uses water-cooled front mounted engines, of flat-4 and flat-6 design, although referring to them as an "H engine". Ferrari used a 180° version of the Colombo V12 on the Testarossa and Berlinetta Boxer models. Air-cooled flat-twin engines were used by Citroën in their model 2CV and its derivatives, while the Citroën GS used a flat-4, and a flat-6 was proposed for the Citroën DS but rejected due to impractability. BMW uses a flat-twin in many of their motorbikes.

hope this helps

Its only the unequal length manifolds that make em sound like they do on Scoobys.

Put an equal length one on and they sound pretty normal.

Hence why you dont see old Beetles sounding like Scoobys.

Apart from the ones peoples put Scooby engines in, that is.

Ginge !

rick thats posing speed though


why dont other manufacters use em then ???

they bad on fuel economy or just no point

Unequal length exhaust manifolds make the Scooby sound like that. Most highly tuned ones sound much more like normal cars as they have proper equal length manifoilds.

Tooo slow

edited cos i got the wrong end of the stick lol

Ginge !

thats a scarey thought

so proper wrx emgines are flat 6 or 4

*edited as i wrote size unstead of 6,,,,,, dam corry

if you mean are all scooby engines a flat 4 design then yes they are,not sure about the 2.5lt engines in the new scooby though.

Stavros

eh?

all impreza engines are flat 4 from the 1.8 non turbos they dont do anymore right up to the 2.5s

ive seen 911 turbo engines in beetles and camper vans, as well as impreza engines.

Impreza engines are huge bore and mega short stroke.
Got a load of meat on em too, so got lot of potential.

The 2.2 conversion they do from the 2litre keeps the same stroke, just bored out!

st3v3

with the new 2.5 lt engine tuners are expecting to produce in region of 400bhp/400lbft for about Ł3000ish

Ferarri flat 12 engine work of art!

Moose 130

VW used them for over 50 years in thier cars/vans etc.

Now they have evolved a bit.....



Now they just get very silly.

mid 8's for racing in the 1/4

Subaru Flat 12 Formula 1 engine

Ive got one of them on order for myself

Whilst WRX engiens are 4.

The Legacy (Spec B) runs a Flat 6. Don't know anything about the engine other than that though. Think its a 2.5 or 3.0.

Stavros

Subaru SVX runs a non-turbo flat 6 too
