1/4 Mile Time In A Manual

Great times everyone .... 

One thing that I cant seem to work out is why do the autos move a touch quicker than the manuals   

Ive always driven manual cars and am only a couple of weeks from buying my T and its making me wonder, isnt the manual a little better resistant to damage when moding too  :o

It really has made me re think my auto is for girls who dont know what to do with the a stick mentality  :o

I never know what to do with my hand and left foot when I drive my bros car which is auto 

manuals are more fun to drive but the auto you stall it up on the line to get up into boost and you can keep it flat when going down the quarter where with a manual unless you wish to flat change you loose some time

Manuals hold more power, and can take more rwkw before requiring modifications I.e clutch. The avg seems to be 240oddrwkw for the auto before it goes bye bye, and just over 300rwkw for the manual before the clutch says enough is enough.

The auto are quicker down the qtr, and from some research I have been doing, purely because of the T5's length, notchiness. It's is classified as a 'lazy' gearbox. This is also similar to the T56. Obviously ford are not going to put in a box like a porsche, but it seems that if you did put in a close ratio box, peoples times would improve dramatically. Most of the time on the T5 is lost between 2nd and 3rd gearchanges as they are so long.

Just my 2c

JB, the ratios chosen for the new T56 can be described as 'close ratio'... when compared to T5 ratios and other T56 ratios that are available (I.e that could have been chosen by Ford).

The comparative ratio changes are:

1.49 I.e 2.66/1.78

1.37

1.3

1.25

compared to the T5 which are:

1.52

1.45

1.34

1.37

.... so assuming the same gear change-up rev points, the revs will drop to progressively higher revs in the next gear up.

The problem is that it does not shift, or at least I can't shift it, as fast as I would like, to date.

Valid Points Brian, and yes I think the major problem is speed of shifts, that's where the time is being lost

With your level of torque Brian, you should just start in third....

So is there any evidence that a Herrod Sure-Shift (or other short shifting stick), combined with Transmax Z gear oil actually reduces shift time and therefore quarter mile time?

I agree totally with slow shift times. 0-100 in a manualT happens so quick.......then you shift into 3rd.

I wouldn't necessarily agree with that JB'er, I think treatment by the auto brigade's bad habits goes along way to hurting the box & not the power.

I wonder how much a hollinger is..... clutchless shifting anyone?

I tell you what Scotty, after today I retract all my statements about manual T's, it seems that none of us can drive.

When I picked my car up from Dynomotive Mark had a Phantom Manual (T5) T in that has 302rwkw and did an 11.9qtr at heathcote on the weekend!!!

Both Mark and I cannot believe it, but it's genuine, the guy who owns the car is from the country, and it was in for the same problem as mine, ford had reflashed the PCM and screwed the car completely!

But an 11.9 with 302rwkw shows we can mix it with the auto guys, I want to find out his secret to slashing over 1 sec from pretty much the rest of us around that kw mark.

Not sure if he is a memeber here???????

G'day Jb just wondering if you saw he's time sheet because a 12.9 with 302 rwklw is a top effort let alone 11.9,Got to say I got my doubts to tell you the truth I dont think that's achievable with 302@ the wheels in a Manual

Im not trying to start anything so the manual boy's take it easy its just my honest opinion
