Qtr Mile Times With Manual, And Power Figures With

[RAPHOON]

Raphoon,

Did you drive the car hard in those 2 weeks?? or was it just normal driving?? I dont belt the car every drive, although I will occasionally take it to 5800rpm in first and second, some times third... but usually wont do 1st to 2nd and to 3rd in one hit.. usually take off hard in first and second then chill in third... or hammer from a rolling start in second or third.

I really dont wanna kill the gearbox yet... if I drive relatively sedately with occasional whipping of a Late model camira will the box old up ok? especially if I put in some transmaxZ.

Does anyone know of any T5 upgrade kits?? that can strengthen the box some what, at minimal cost??

Whilst I'm not the gentlest person on my cars, the driving wasn't anything out of the ordinary.

The point I was trying to make is that its not so much the peak power that kills the gearbox, but the torque pushed through it.

Mine was programmed (as requested by me) to give me as much punch as possible as soon as possible in the rev range. The car was VERY good, with craploads of torque from down low. It was THAT which affected the gearbox the most. The high end of the rev range is not usually where the GBox damage is done (feel free to correct me).

Therefore, if you are concerned about your gearbox, then ask your tuner to limit torque increases down low, and to bring in the power/torque more gradually. This should increase the life of your gearbox as well as provide a more linear power delivery.

cheers Raphoon,

I sort of knew that it was the torque and low down grunt, and Simon is aware of my T5, and at the time standard clutch, so power was delayed to save the clutch. Now I am going for even more power, so I guess the low down grunt will have to be slightly delayed yet again, at least until I have enough coin for the T56!

I dont mind having the power come on gradually, feels good when the boost really kicks in around the 3500-4000rpm, can only imagine what 300rwkw will feel like!! I'm just trying to get as much info as possible and prepare as best I can!!

Mate, I don't know about what others think but....

I have had an APS phase 2 tuned by APS in Bayswater to 268rwkw and the T5. I was happy with this as the gearbox showed no signs of dying and the car was a fair bit quicker.

I then spent a fortune and went to a Nizpro stage 2 tuned to 338rwkw by Nizpro in Baywater and had the T56 fitted. My personal experience has been that the car feels to me only marginally quicker, if at all. If you are going to fit the T56 to a Mk1 factor in the cost of a diff ratio conversion otherwise you are spending a stack of dollars for very, very little gain. I am in the SE suburbs of Melbourne so shoot me a PM if you want to come for a spin or even line up against me so you can see the (lack of) gains for yourself.

mate forget about the t5 box I had 313 rwkw & said to myself this box will last ,,4 weeks later very noisy box & that's no burnouts that sux all that power &you cant fry them.

cdm,

I dont really want the T56 for the extra performance (sorry if I sounded like I did) I was more interested in it for its ability to cope with the extra power and torque. However, if I'm heading that way, I will send you a pm and take you up on your offer, that would be great! cheers

ballbreaker,

so your driving style wasn't too aggressive?? I'm by no means an aggressive driver, except on a few occasions. So driving normally will still hurt the box that much?? When I say normal, I usually shift at around 2200rpm to 2500rpm, and only on occasions take it past 5500rpm. usually taking it to 4000-4500 had enough to blow away other cars.

well since starting this thread, on advice from Simon, I am now adding a fuel pump and hi flow cat. So the power will inevitably push 300rwkw... so I guess I'll really have to see how the T5 holds up. Hopefully my driving style can at least give me a year!!

if any one else has experience with the T5 and this power level, that would be greatly appreciated!! I suppose the thread has changed some what since it started out as being about qtr mile times and power figures for the listed mods!! Sorry for the random change!

I'm still interested in the qtr mile times with the T5 and the mods I've listed, so if you have advice on that, please feel free to mention it!

No worries. I must have misunderstood the question. However if you weren't after the performance (ie, 1/4 mile times) why would you want the extra power? The point I am making is that if you want to go quicker (as I did) then you are better off settling for about 280rwkw with the T5 as this will give you the same performance as a Mk1 which has nearly 340rwkw and the T56. I'm not sure how else to say it.....You could spend $10 000 by the time you get the gearbox fitted, and the extra bits required for the power, and the car will be NO quicker. In other words, you would be better off taking your $10k and buying some Heroin from Bali...There is no point getting the T56 to run the "extra power and torque" as even with this power and torque you will be NO quicker. Unless you are chasing 400rwkw plus, I don't think the gains are worthwile.....or.....unless you change the diff ratio as well....

In fact, I imagine, if you have any less then about 330rwkw with a T56 in a Mk1 you will actually GO SLOWER!! I learnt the hard way...My only saviour now would be to go more power (too expensive as I would have to do the internals to cope) or swap the diff ratio to 3.73 or 4.1 which I don't intend on doing any time soon as I would rather not spend any more cash on this car.

Seriously...before you commit to ANYTHING, give me a buzz...

I'm not trying to be rude mate, just trying to save you a few bucks...

By the way....Street Tuner ran a 12.6 sec 1/4 mile in a Mk1 with T5 and 280rwkw....I believe this record still stands for the quickest manual....

cheers cdm,

I see your point, and you make good sense. The only thing is, if the gearbox does play up with 280rwkw, or 300rwkw, I will need to upgrade it. If I can get away with not having to change the box, I would be more then happy!

I think I will have a chat with Simon and see if he can do a tune to hit around the 280 mark. It should do that comfortably with the mods I have planned.

I guess what I mean is, if the gearbox plays up, I will more then likely opt for the T56, even if its slower, as there would be little point in putting in another T5. Unless there are stronger versions of the T5?? but I havent heard of anyone speaking of these. Or is there a way to strengthen them?

I dont want to go for anymore power then 300rwkw. And from your advice, I think I might have to chat with Simon and see what we can come up with.

Thanks for the help, and I do appreciate the fact you're trying to save me some dollars!! As I too do not want to go out and spend too much more on this car!

I will pm you shortly.

Hey Jimmy,

I am (or will be soon) in the same predicament as you. One other option that was put to me was to try to pick up one of the Tremec TR3650 gearboxes. I gather that these are not as strong as the T56 but I have heard of some going quite cheap (like $1000). I can't actually say what else would be required to do the conversion but it may be something worth looking into if the T5 bites the dust.
