Fastest (un-opened) XR6T in AUST

BOSSED · 10-05-2007, 12:47 PM

Last night at WSID a CV PERFORMANCE XR6T went 10.89 @116 mph with a 1.51 60ft,this with a std bottom end which is now the new record for a std motor
1st pass he went 10.9@122 mph and second run he did a 10.89 and blew a intercooler hose just after 3/4 track thus why the mph dropped

gtfpv · 10-05-2007, 03:02 PM

bloody nora . EAT THAT HSV. !!!!

ADSXR8 · 10-05-2007, 03:10 PM

WOW, its all in that 60ft time. Job well done Con and Vic.

Do you think these times will be improved when the software comes available for the 6spd auto?

awesome time,
i bet its got a huge amount of other mods thou,diff ratio?
multiple fuel pumps,
separate fuel tanks
was that on nitro?

cheers mark

No mate not at all its still std diff ratio,4 speed box only 1 inline fuel pump

No seperate fuel tanks(surge) and no Nitro or Nos

Great time is that with a factory turbo, compressor housing & Plenum ?
Congrats.

cool,great time-

amazing, guys my age can remember when pro-stock ,and other racing classes,where running those times,

i have to laugh in excitement when street registered cars are running those times,well done,!!

cheers mark

p.s.when i was a lot younger anything under 14 sec quarter was considered quick for a worked street car!!!you've totally blitzed that

by light years lol

Redrum · 10-05-2007, 06:58 PM

Awesome time and mph. Would love to know more details.......

Fantastic time, any plans to get it set up so it can keep going and aim for a 9?

ARE YOU SERIOUS a 9 get real,to get to that you would basically have to start again!!!do you realise how much difference there is between the time and a low 9?

Money & Commitment until you succeed, if you fail get more money and put in more Commitment.

There has already been a 9 run by a T so its possible

bdave351 · 11-05-2007, 10:15 AM

Considering how easy it seems to be to make power on these motors (I have spent less than 1500 on mine and have 249.2rwkw on CV's dyno) I dont think its going to be a power issue to make the 9s.

More someone being prepared to mod the rest of the cars suspension etc (and mandatory safety stuff like putting a big cage in your shiny new falcon.)

No mate the owner is happy to stay at this level

A street registered one!! or one that arrives on the back of a trailer??

i am not so sure-when you say nine you are probaly saying 10' or 9.99!! to get a 9' or a low nine would take more than a roll cage and a few suspension mods!!

Do you have much drag racing experience?may I ask?

cheers anyway

bdave351 · 12-05-2007, 07:05 PM

Lotto, I dont know where you get a low 9 from, so pull your head in.

When its a big place like CV I doubt they would have to much trouble getting it into the 9s if the owner wanted it (And had the moolah to part with!)

Ive seen pics of the 9 second XR6T but havent seen any specs, anyone know much about it?

Cobra · 12-05-2007, 08:36 PM

The 9 second T was done by HPF (Horse Power Factory). Slicks and front runners, dropped exhaust, interior stripped, 90/10 shockers, C9 3 speed trans, and every conceivable mod possible on the XR6 Turbo I would assume.

the nine second one had standed turbo but was moded, race fuel, standed diff, c9 trany, slicks, front runers, seats out, with race seat,rego'd car but did not drive to the track because of exhaust off, and race fuel,
i think he said the motor had forged pistons, rods, and valve springs,
nizpro plenum, and some other intercooler(big one).
it also ran 2-3 10.1's ithink 1 10.0, and the 9.9, @138mph
it also ran 144mph on one pass, but this was out of the blue, and was never close to that again, ithink it was 420rwks, and a heap of torque.guy's name was adam,

What difference would it make? Any car running these numbers would not pass rego anyway, that argument has been done to death.

It doesn't really matter IMO, we race our daily drivers all the time and to race them at the level we wish to it is easier to prepare them in the workshop and send them up on a trailer so when you get to the track you are relaxed and ready to race. I hate getting there and having to spend an hour or so preparing these cars, different in big time drag racing though.

In the "street car" scene with the ford and holden classes we have opened or unopened categories anyway so it's your choice if you want to strip the car or drive it there and off you go.

It is extremely difficult to run these current model cars down the track with everyday street rubber you really need slicks.

XRQTR · 13-05-2007, 08:39 AM

Is this with the standard top end re: valve springs

Still a good time don't get me wrong, but what constitutes unopened??

cheers thanks for answering my question,i NO the answer!!

not many people driving down george street,with no exhaust-slicks-race fuel-and other mods!!

totally different ballpark!

Phew just had to look back I thought I had missed it LOL.

No the point I am trying to make is that the initial post claimed the fastest time for a standard motor, what I am wondering is what now constitutes a "standard motor".

As valve springs are definitely part of "the motor" I just find it very confusing, not to mention somewhat hypocrytical considering the uproar over LS1 springs, that this could be classed a s a "standard motor".

To me a standard motor would be one that still has all the original parts it left the factory with, if you choose to reset them in a way to suit your needs then it still remains standard as you have not replaced parts with better/higher quality/tolerance ones in order to gain performance or power.

I think before people start to claim records that there needs to be some kind of guideline, a checklist if you will, for people to run from in order to have a fair and level playing field. I mean it's like the Nizpro dyno day rules where some internals are allowed to be replaced and still remain classed as stock, how does that work??

Look, again I will say that I am not trying to take anything away from the tuners or indeed the owner of the vehicle, I am simply asking for some kind of clarification as to what actually constitutes stock or standard. It would be easier for everyone, whether racing/competing for the title or just watching from the sidelines in appreciation of these feats to know what is what.

lotto · 13-05-2007, 04:30 PM

yes xrqtr-i do agree in part,

that major internal changes-rods-bearings etcand yes valve springs to a lesser degree,but problem with valve springs on the particular mentioned models is that they are a more than well known factory weakness compared to the rest of the car,and a needed change or we wouldnt get anywhere-but i can see where you are coming from.

what i find frustrating,and i am not talking about the original post here!!

is when people dont realise that over a quarter of a mile ,when you are getting into quick times-that a fraction of a second means so much!

and to say that you can get a car that is running mid to upper tens,that with a few more mods you can knock another second or so off is so wrong,and anyone who has had a lot of experience drag racing-would know better and not make comments like that--

i dont have a problem with valve springs as even daily driven ,slightly modded falcon turbo drivers -in this instance in there right mind would change them!

but to say that a car running in the 9's, that has a totally new bottom end-race slicks ,no exhaust,race fuel-cam and head work, is a daily driven street car is ridiclous ,because it is a totally different class of car compared to a street one!

anyway my opinion only-

cheers guys

i enjoy hearing peoples opinions -even if i dont agree-we all learn-i learn new things everyday!!!

ratter · 13-05-2007, 07:25 PM

Valve springs on the T are a performance gain as they allow more boost to be run in the motor, if valve springs are allowed why not allow forged pistons, better rods, etc and still be classed as unopened.

It is quite a debate whether valve sping replacement on a LS1 is acceptable as being unopened, but the LS1 racing class rules allow it and the majority do it as it allows the motor to retain the factory performance because the standard springs are weak and start to bounce at revs after some use.

The T does not suffer this problem until boost pressures are increased, so it is not a reliability issue, it is a perfromance issue.

Spot on ratter, it still makes me laugh that the LS1 boys can class valve springs as an unopened motor.

Might be a stupid question but how exectly can you make a XR6T go harder without adding more boost?
When you add boost you need stronger valve springs..If your gunna be that anal with saying valve springs then there should be different classes for guys who changed diff gears or do work to the gearbox as thats a performance issue,not a reliability issue
