Ex-FPV engineers create 700Nm XR6T

Are those photos taken outside of Prodrives office? Looks the same.

What sort of boost pressure would these cars be running to get that much torque???

Wonder how long the transmission will stand up to this sort of torque???

Great package for 40K too.

700nm lol thats cute

Their address appears to be in the same complex as the Prodrive race team:

Which is across the road from the old FPV factory (33-49 Glenbarry Rd).

Well that's convenient...LOL

if you google / look at the the names on the website you will see its the enginnering guys who were FPV/prodrive.

The Fg Turbo's claimed torque figure is 533 Nm, but when I ran my stock untuned 2009 FG Turbo Auto at WSID last May, I launched it in 2nd gear on the first run and the 0-60 km/h time was 2.61 seconds. 0-100 km/h was 4.85 seconds and 110 km/h came up in 5.52 seconds. That was all with the car in 2nd gear and a close look at the data indicates that the upchange out of 2nd gear started between 111 and 112 km/h (I've got the same accurate test gear that Motor Magazine has been using, also I got a 12.731 second Drag Strip time slip on that run).

That raises the question of just how many cars could equal these times using such a high gear from the start to over 110 km/h (and actually I'm thinking that not too many can match that even when their 1st and 2nd gears are used).
So the question is, how much torque can the FG Turbo's really put out? I'd say well above the claimed 533 Nm (ie. with the overboost operating and Premium unleaded fuel).

My Dyno sheets suggest at least 650 Nm at the Flywheel on 98 fuel, but that was when the car was treated aggressively enough (and brought to normal operating temperature on the Dyno) to get the overboost working. That raises boost from about 9 to around 10.5 PSI.

My end speeds at WSID were close to 180 km/h, which is similar to other untuned FG results posted on the Net and I think that points to at least about 320 Flywheel killowatts for these cars.

Also I believe the F6's have an overboost function which gives them about 10% more power and their 310/565 Nm claimed figures were apparently obtained on 98 fuel, so I think 340 plus kilowatts on 98 fuel certainly fits with their known real world performance.

I'm wondering if the 700 Nm XR6 T will get a better intercooler like the F6, that should help it to keep maximum performance up for longer I think.
I wouldn't expect my stock XR6 T to keep it's maximum performance up for too long on a race circuit, but the overboost certainly works in normal everyday real world driving situations.

53 extra nm of torque with overboost at speed,temporarily,apparently lol.

You did that on a stock auto transmission?

Yes Zilo the transmission is absolutely stock and I think I've been able to prove in earlier posts that the engine is standard as well, but I guess you're thinking that I might have given it a higher stall converter, it's hard to imagine that they've got that much low rev grunt.

With that in mind, I'm showing details of the 0-110 km/h part of the run which shows the acceleration profile right up to about the 58-5900 revs that the engine was doing in 2nd gear at 110 km/h.
When it's being stalled up the car starts to pull quite a bit harder on the brakes just after 2000 revs and I stalled it to about 2250 for a good launch.
There was no wheelspin as I have mentioned in earlier posts and you will note that the acceleration pace dropped off between 40 and 50, which is when I would expect a standard torque converter to lock up in 2nd gear and from that point on there is no torque multiplication from extra revs, hence slower acceleration.
If I had a higher stall converter the car would have had torque multiplication to a higher road speed and would kept the better acceleration up to a higher road speed when it would finally lock up.
In any case a high stall converter would have to be about the last mod that I would ever consider making to my car. Huge torque for launches on the street as it is.

0-10 km/h.................0.43 sec
0-20.........................0.85
0-30.........................1.24
0-40.........................1.64........in 9.01 metres
0-50.........................2.09
0-60.........................2.61...........22.54 m
0-70.........................3.15
0-80.........................3.70...........43.78 m
0-90.........................4.25
0-100........................4.85 sec.....72.51 m
0-110........................5.52...........92.17 m

Finally I can supply you with the DBN Racelogic file if you like.
You could perhaps PM me with an email address. Then you could download the Racelogic software and examine the complete run in detail if you want to.

Yes zilo... I did the same but ran a 12.8 dead stock. I thought more people new about these cars more. This premdrive car is a bit to existing xr6t owners. A used F6 with bilsteins and a tune is a better/more powerful car.

Cheers mate, don't doubt it for a minute.

Just flogging the auto that hard (and as others have mentioned the over temps and limp mode) can't be too good for the transmission to be lasting too long.

I've built a twin turbo 720nM/310kw beast and had to fit custom steel separator rings, custom wave spring and double the number of friction clutches in kevlar to stop it frying out as well as a modified valve solenoid assembly to increase oil flow and extra oil coolers.

One launch was enough to fry the fourth gear in seconds in stock.

You guys must be extremely lucky to have a stock auto hold up so well.

Or has it?

Putting your foot down isnt flogging the auto.

I'm at 96,000 k's so far and that stall was 16 k back. No problems so far, but I wouldn't expect an occasional launch like that to hurt the transmission. Particularly given that the car had been standing for more than an hour (other than brief start ups to move forward in the line).
I should have mentioned it was a brief stall and way too short to overheat the transmission.
Notice that the acceleration rate increased between 20 and 40 km/h. Perhaps I mightn't have stalled for long enough to get full boost, or the electronic nannies would only allow a certain amount of torque at the launch.
Whatever the case though, I'd expect the nannies to stop any damage in a standard untuned car, unless of course there was already a problem in the transmission.

A bit off topic I know, but if you're interested in times at the track, a VBOX sport can now be purchased for about $500 I believe. You can get so much more useful, very accurate data out of these devices than a time slip gives.
1/4 mile and all times from the 60 foot point on can vary from about about 2 to 4 tenths, depending on how you stage the car and you can see in fine detail where you're losing or gaining time.

Doing so at at circuit must cause the trans some issues over time hence I bypassed the oem unit & put in a trans cooler with a Derale bypass.

$40k for a second hand xr6 turbo with mods

good luck.....
