At the end of the day the anything with a grove or tread pattern can be driven on the street and you will more than likely get away with it... I drove around on MT ET Streets for a few weeks after running a 10.8 sec pass (too lazy to take them off) its got a tread pattern, does that mean its a street tyre? Not really ... I thought that this was not so much a top 25 competition but a thread where you can see what times people are running on similar tyres. I had more fun running the low 11 second passes (probably 30+) on the Maxxis than the 5 x 10s passes on the ET Streets. I have not been on the forum much lately, It's good to see some great real street trim times !!

You guys still playing with the taxis !! I miss my car...

So we still need a cage to run in the 10s ??

Great news !! Mmmm... I've still got the taxi and she might need a bit of TLC but it's now worth going for a few runs on some semis. I've been booted 5 times for running in the high 10s at least now I might get a chance to have a bit of fun without having to be sent home early... Might be a good time to sell?

Apart from the Taxi I have a Manual FG XR6T which killer the standard bush within the first 1000 ks of giving the car a hard time. The fulcrum bushes are the way to go...

Getting closer !! to my pb of 11.15s on $200 19" Maxxis... I have not run the old taxi for about two years and the car feels even stronger with the latest tune with a few extra little mods but I'm not keen to take it out any more and will be installing a strong standard stall in it that will make it a nicer daily driver. Hence guys here is my 2 cents worth of wisdom that might help get you guys to a lower pb... especially on street tyres. The key is to take into account and appreciate the physics behind what yoyu are trying to do. With the autos once you get off the mark and assuming that you are not breaking traction mid-track and you are shifting at the right point then the MPH and ETs should be very close on any particular night depending on the 60' time. Now based on the 100 odd passes that I have done in the taxi and some experience in a few other cars here is the trick to getting off the mark... Whatever improvement you make at the 60' mark then you will gain about 1.5 times that gain but you might loose 1 -2 mph. Note: The track gets better towards the end of the night, the dust/dirt is blown away, some extra rubber might be laid down and the air gets colder. Hence you should see traction improved off the line and power come up a little. That is my theory ... Think physics ... you can only put so much power to the ground off the mark based on how much torque the engine makes if you get it wrong te car either fries the back tyres or bogs down off the mark. Finding the right balance will get you the best 60' time. On ET Streets with 375rwkw (on a dynapack) I did a 1.53 60' launching at about 4psi. With similar power I could only get a clean take off with a max of about 1psi of boost which resilted in a best 60' of 1.78s on the Maxxis. So what do I not do? ... I do not stall it up at my target launch boost hold the car there and then just take off abruptly. The autos do not like it and you are not using the momentum of the motor and turbo to ramp up the torque. The trick is to bring up the boost slowly and as it reaches the target boost then nail it, hold the brake a fraction of a second longer and then let go of the brake. The car takes off smoother and you get to that 60' faster!! Vevapower, based on your 60' and MPH you can run a high 10s pass with your current setup and tyres but you will need to pick a good night. I hope that makes sense and you guys get some better times ... Good Luck!!

I'm outa Sydney otherwise I would have come down for a look... The Taxi has not has a run for a while maybe next time! Let us know how you guys go ...

The best I've done is a 1:53s on ET streets in full street trim 1920kgs, 4sp!!

Guys, I just want to let you know... the taxi is for sale!! I think that it is still the quickest (true) street tyred XR6T/F6 ... 11.15s@125 MPH on 19" Maxxis tyres. (click on link in signature for details)

Hey that's my tag lie (ha ha)... but you can use it as you've more than earned the right !! I'd love to see the car sometime.

Wow ... well done Phil and to the boys at TRP. I cannot imagine what the ride would be like in a taxi going that fast!!

I visited Fulcrum (distributors of Teins in Oz) and can tell you that these guys do a lot of local r&d, setup and testing. I have an early set of Teins in my FG and I dropped the car off to them the other day. They are going to go over the car (had the suspension in for while) and they are assessing the shocks, springs, Superpro bushes and general suspension setup. I do a lot of country driving and the shocks cop a pounding on the open back roads in NSW. I also found that the Teins in my old Skyline R32 GTR where very street compliant and great on track days. I've been in XRs with both setups and there is no comparison. It's one thing to go low but its a totally different story to maintain ride quality and handling. The Tein Superstreet packages a a great all package.

Getting there guys ... getting close!!

Yeah its hard to part with the ol'taxi ... the car has provided a lot of fun and has been super reliable but she might be uo for sale soon as it is just sitting around these days collecting dust and my attention has shifted to getting back into some circuit stuff... You are really getting the ol'girl going these days... well done mate.

Wow Phil... you still have the old girl and it's certainly going stronger than ever !! Congratulations ... It will certainly be an interesting drive now. Are you going to have a go at the quarter? Just hold the transbrake button, flatten the loud pedal, close your eyes and let go of the button. Should be easy (not!!) Inspirational stuff, I still have the ol'taxi sitting in the garage collecting dust. Might have to take it out for a few runs.

The car weighed 1920 kgs, full tank with my fat ass in it !! ...

Come on guys ... so is the Taxi still the "real" street tyre king?? 11.15@125MPH on 19" Maxxis ...

Some good times there !! ... Street rubber runs gives you a good chance to get a feel for the car in street trim. Highly recommended for the young blokes (and the oldies like me) who might not have the experience!! I'm getting the itch to get out there with the taxi on some fresh street rubber and try and sneak into the high 10s!! I've got a couple annoying issues with the taxi ATM and will look to sort these out first before I go out again.

That is a great time on a stock car. I've managed 1 run in my FG... I had a injectors, dump pipe and a tune on my FG Manual XR6T and did a 13.0 with wheelspin in 1st and 2nd during the first run. Then broke to oil pump while doing the burnout on the second run (my fault, valve bouncing it off the rev limiter!!) The more power/torque you have the harder it is to launch these cars and get them to the 330' mark cleanly... after this the manuals should be on par with the autos ?? Good to see some manual shifters having a go. I also believe that the ZF is a great box and agree that it is all too easy...

Well done, congrats on the new PB ... an explanation is maybe heat soak??? These cars generate and retain a lot of heat and that effects horsepower and hence you are down a couple MPH. Cooling the car down between runs may help you be more consitent. In my experience, 1 tenth improvement in the 60 footer equates to about 1.5 tenths at the finish line. An in general you will see a slight drop in MPH.

The B series is definitely showing their age (nearing 10 yo) but there are still some good ones out there. I've got both a FG XR6T and a BA XR6T both have their good and bad points but in general the BA has been a far better car and more reliable especially under punishment. Both are modified but I get such a tinnie feel out of the FG motor and the overall build quality does not seen as good. Call me a clingon, old fart or whatever ... the B series are still a better bang for your buck if you are going to modify the car and want to get some serious mumbo...

Relatively cheap fix ... anyone had an engine, oil pump, gearbox covered under warranty when their car was flashed/tuned??

Yeah, I've got a couple problems with it atm. Valve springs & Actuator?... But I want to get it sorted and I will be out on some decent 19s to try and senak into the high 10s... the Maxxis dont want to sneak in the 10s. 11.15s@125MPH is as good as they are going to get. I also have a set of reasonable good MT semi-slicks and a set of MT full slicks at home, I just need some front runners !! Should be a fun season this year !!

MPH is down... Should be interesting to see how you run with the Valve springs... good time on the 19s!!
