GT gets Superchipped

[Jaymz]

To get back to the subject, James was kind enough to offer me a lap in his superchipped pride and joy. Thanks man, it's a big deal to let someone drive your baby. There's no way I'd let a shifty looking guy like you drive mine...

Talk about shifty, i can't believe you brought your dad to the event. How was the videos he shot!

We ended up with three blokes in the car, so you need to factor in an extra 150kgs of man meat. Can only imagine the joy of solo flight!

MY GOD. This thing is just a TDI on roids. It felt like there was minimal lag straight away, and the torque rush just kept on going. I only gave it the odd, half arsed squirt, and it was damn impressive. I am absolutely sold on the upgrade, and Jamyz has himself one nice machine.

On the dyno the difference between cars wasn't as great as one would expect, but then James DID do his run with the air conditioner on. DOH!!! Allowing 4-6kw for that, and the difference in KW is about 15 at the wheels. Otteinger ( spelling?? ) claims 18kw over 125, so it sounds right.

This does however put ol J-man in the same park as a stock GTI that ran today with 128kw.

What was also suprising is on the dyno comparison the torque curve didn't "seem" that different, certainly not like the graphs otteinger depict on their website, but James may be able to pull the actual max from the graphs. To look at the superchip power curve, torque curve and especially the air / fuel ratio, J-man has lots fatter and broader curves, and a nice flat AF line. My factory Air Fuel line is all over the place.

Bottom line is to drive the two cars is an ASTOUNDING difference, and I see the cost of a superchip as an EXCELLENT investment.

Seems the real world bumometer tells me the result is FAR more than the numbers would depict.

No problem at all, my friend Yes its amazing how much different it feels on the road to what the graphs depict.

This graph shows the difference between Gregs car and mine, both power and torque curves are plotted. Although the output is not the top run my car did on the day & give or take a few kw's for someone leaving the a/c on the graphs should still have the same curves


This one shows the top run my car did on the day with AFR's.


Greg has sumed up and confirmed by driving my car ,what its real character is. So folks if your one of those people who thinks its all about the numbers & you want a dyno queen then this retune is not for you but if you want something that is really responsive and has plenty of torque over a wide rev range then maybe you should consider this retune.

Thanks for the post mate, interesting to print and work out the torque numbers.

What IS very interesting is if the stocko TDI pulls 113kw, and is rated at 125kw, it has about 10% transmission loss. Certainly an efficient tranny, but not outside the relms of possibility for a modern FWD. I suspect the diesel gearbox would be more, as it's supposedly a tough thing, so my folowing summary is probably on the "down" side.

The stock torque rating according to the dyno is about 356nm at the wheels.
At the same 10% loss from above, this puts the fly torque of the stock TDI at about 380nm. Very very healthy.

Given the aircon factor in your superchipped car Jamie, I'd guess you are around the 420 nm mark at the fly.

In all, it sure seems the ol oilers are pulling some impressive numbers where it counts!
