Turbo Performance

[Guest TurBski]

hey, im currently looking to buy a performance vehicle. Specifically im looking at the XR6T or something like the 200sx s15. What I want to know is how these cars compare in terms of the boost you experience. Anyone who knows could you plz give me some advise.

[Guest IMTRBO]

I have driven both and the xr6t is much more faster. The xr6t has a gerret t35 if my memory serves me correctly which is a big turbo and speaking from experience nothen feels better than a massive snail in you eninge keep in mind that the xr6t is only running at 6psi and with the right Unichip or Motec Ecu if you have the money you can get your car in to the 13 second club with out much bother... I found the s15 a little to small for me and the emergince back seat was a little restrictive. With an XR6T you have the luxury of ordering it new with all the bells and whistels .. Ie Leather Premsound and 18's all factory you have to buy a GT s15 to get front leather which suxs but if you in the market for a s15 and decide that is the car for you get an imported version with factory LCD and more powerfull than the aussie version ...... Also comes with factory boost gaguge!!!! Hang around this site long enough and you will be in your local ford dealer choosing a colour ( I like the burnt orange ) nudge nudge!!!!

Have a real good think about the physics of the whole thing...

An XR6T has 4000cc of capacity. This means that each cylinder fills up with a certain amount of air fuel mixture. The Turbo increases the density of the oxygen thus increase the size of the charge. Regardless of the boost pressure (which in the event of the Falcon, is 6 PSi) the engine is sufficiently well designed to put out good power and torque with NO compromise on longevity.

Now look at the Nissan (or any other Jap turbo thing)

They have two less cylinders (therefore less mass reciprocating around the crank) less capacity (less stroke, so less torque) and more boost. So the boost makes up for the loss in capacity. However, this means more load on the pistons, rings, bearings, crank etc. In the case of a GTR or a Supra, they may be six cylinder but their capacity is still very small compared to the Falcon.

Now make a number of mild modifications to an XR6T. Increase the boost, attach a piggyback ECU to the EEC5, change the exhaust to make it more free flowing and what have you got?

A bigger, more powerful engine that has been modified for not much cost and still has very little compromise on reliability and longevity.

The XR6T engine has really only been about for a short while as opposed to the jap stuff that has been modified for quite a few years. The amount of reliable power and torque that will eventually come out of the Falcon motor will be quite extraodinary.

The only way to get more power out of an engine is to fill it with as much fuel and air as possible. The more of this combo, the more force from the explosion that pushes the piston downwards. That's why Doorslammers and Top Fuel Dragsters make over 3 to 4 THOUSAND horsepower with their Supercharged Chrysler Hemis (which are over 8 to 9 litre by way of bore and stroke)

Do your self a favour, aim towards an XR6 Turbo because a good BIG one will ALWAYS beat a good LITTLE one.

Like your thinking plonky I agree with all above !!!!go the straight 6 turbo!!!

Wow plonky

TurBski,

Take a look at what the others are saying and consider this also.

The XR6T is a complete package. Large and comfotable, extraordinary performance and "point & go" handling for a relatively large vehicle.

You would not be dissapointed in any way with this car.

As others have said, if you've got the money you can option it up to the hilt.

Make no mistake, this car is already a major cult car and for all the best reasons.

I'll predict it will get the gong from Motor Magazine in the "Bang for your Bucks" next time.

Go for it and join the happy people........ Before it's popularity allow Ford to increse the prices!!!

Mack......

You only live once ... ENJOY IT!

I drive a Silvia at the moment, and taking delivery of my XR6T next week, so I am not biased.

Plonky, in your physics lesson, you forgot to factor in the weight of a car. A heavy car is basically

more comfortable, a light car is more nimble.

To make the heavy car go as fast as the light car, you need to give it more power and a heavier driveline

resulting in much higher fuel consumption and "more load on everything".

I'm pretty sure the nissan only runs about 7psi from the factory also. The boost doesn't make up for a loss in capacity.

And if you think that Ford can build a jap-style engine better than the Japanese (vvt, twin cam, turbo, etc.) first time around,

think again.

That being said, I can't wait to get the ford and lose my Silvia, because I am looking forward to a more comfortable ride,

that can MATCH the Nissan in a straight line, even if it is going to cost me a few extra dollars, now and at the bowser.

My suggestion, take both for a good strap and decide if you want a quick big car or a quick little car.

If we are discussing reliability, just do a search on "blown up" I can't find any reference of a T engine , even a modded one letting fly with engine internals becomming externals....Sure, hoses come off and some trouble with little ancillaries ....It may still be too early to tell but given that there are no glareing flaws with the barra, I think plonky's spot on, what wears out an engine? RPM. The 2ltr motors do more RPM to make up for the lack of cylinders (boosted or otherwise) bores wear, rings wear and bearings wear. The less RPM for a given power figure the less engine wear. So reliability wise my money's on the falcon. (And yup, an 8 will last even longer...) Anyhow, that's how I think if im wrong ...edumacate me , cheers!

Friction wears out an engine.

Piston speed is one factor in friction.

Good Engine design will lessen friction.

Take Honda for example, high revving

, high mileage engines. High power through

technical development not increased capacity.

high revving engines are generally more fun to

operate also.
