how does the standard computer cope with twin TBs ???
could you put up a pic of the twin TB manifild and a price please?

Mark

you have PM

when i am hanging around with my toyota mates and they are talking about qm times etc a few have fast cars and they have done low to mids 12's and low 13s etc...

When i hang around my ford mates they seem to talk about fast being low 15s down to mid 13s...

Now what i want to know is what kind of qm times do u think an ef with a stage 4 kit, exhaust, shift kit and xr6 diff would do? I know most people here will say they are real fast cars but are they compared to rexys and supras etc which my mates drive?

before i get flamed: I want a car that is reliable and drivable with heaps of torque and i think mark is offering something awesome to everyone and perfect to me for what i want and im not having a go at fords or his rebuilds but i just would like a comparison to other cars so i know what ill come out with in the end...

You won't be near low 13s to 12s thats for sure!
No offense Chris, but an Auto I6 falcon as it stands isn't exactly a fast car and you can't try and compare them with modified supras and the like.
One of Marks stage 4 engines will be a huge improvement but hoping for low 13s to 12s is a bit optimistic.

I've just had a stage 4 fitted to my EF manual and I'm expecting to pull low 14s or hopefully squeeze into the 13s. I don't think you'd expect more than mid to low 14s out of an auto - which is still quick and good bang for buck when you look at how much your mates are paying for insurance

Yeah,

What Hyena said mate, I agree.

Fords are big and heavy and the auto gives you only a couple of gears that are truly useable for the full 400m so you have to be realistic with what you can hope to achieve.

I have spent $2000 and a lot of time and 15.6 is all I can manage.

How fast do YOU want to go and how much money do you want to spend?

Yeah it doesnt bother me if i cant keep up with them in a qm time but was curious to see what sort of times it would do.

I like the way my ef drives because it has enough get up and go when i need it and then i can still put a helloverlot of people in it and drive down the coast for the weekend etc... so if marks stage 4 engine is a "huge improvement" then ill be extremely happy

My mates old celica with a 1ggte went good (12s) but try put more than two people in it and drive it.

The falcon is a solid tough practical car which i reckon is the best of both worlds.

Yes the stage 4 will be a huge improvement, you don't need to be a rocket scientist to work out that almost double the rwkw is going to make a big difference to your cars performance.

It really all comes down to what you have to spend. If you wanna throw 4-5k at it then go with one of Marks engines. Maybe even look at getting a manual conversion and a engine one stage down.

If you don't have that sort of money to spend then look at a wade stage 2 cam, extractors, cold air intake etc. That will give you a decent noticable improvement and cost you under a grand.

Have a look around the 6 cyl forum, you'll find all the answers several times over

Hi guys
I'm going back to cresent motorsports on saturday to re dyno my car as my car leaned out to the max 18 to 1 changed injectors to 35 pounders and a 4 bar reg never seen so much black smoke in my life, so i put 24 pounders with a 4 bar reg lovely and done a computer reset.

on saturday we are going to try different injectors and regs i will let you know and see reports and charts of the out comes.

my exsisting reg did bugger up and after testing injectors 2 of the spray paterns were not nice just dribbling

One thing that interests me is how much torque does each stage dev kit put out?

Power is one thing, but it generally only looses your lisence for you =-(

But torque, thats just fun =-D

Thanks

Hi Mark,

Whats the situation with your Turbo Project? Is it coming allong?
Love to hear about it.

Power (KW) is derived from Torque. No torque means no power.

Good point. Whats the difference between power and torque?
Torque is the engines ability to resist all the forces that try to make it stop, friction for example.

Buggered if I know what power is so....

(insert cut and paste)
In the simplest terms, torque is the twisting force the engine applies to the crankshaft and then on to the transmission.

Power, by contrast, is measured as the torque times the rotational speed. In imperial measures, one horsepower is equal to 550 foot-pounds (of torque) per second. Two engines can produce the same power but have very different torque ratings for the following simple reason:

One horsepower can be produced by moving one pound 550 feet OR by moving 550 pounds one foot, provided that either function is achieved in one second.

The difference comes in the fact that the high-torque engine will be rotating slower than the low-torque engine at the same power output but it will be twisting the crankshaft a lot more vigorously.

In theory, different gear ratios - most commonly four or five in cars' gearboxes - should mask different torque characteristics by altering engine speed to suit but the reality is that engines which produce high torque figures at low revolutions respond much more readily in give and take driving.

The practical advantages come in the form of reduced gear changing, lower engine revs and wear and, invariably, lower fuel consumption in all conditions other than constant speed driving.

For Mr Average, torque is therefore more important than horsepower, unless you spend your life racing around at high revs.

Power (kw) = Torque(nm) X rpm / 9549

As an example, the factory AU makes 157kw @ 4900rpm. therefore, it's producing 306nm @ 4900rpm. Alternatively, when the engine is producing 357nm @ 3000rpm, the power output at those revs is 112kw.

but then how do u explane how the torq drops but the power dont???
