Power Happy Median

[TUFXRT6]

Ok Guys & Girls,

After seeing the number of first time up graders post questions that would lead others to believe the owners of these cars really shouldn’t be playing with sooo much power I thought I would ask the question.

Ruffly what point do XR6 turbo’s really start loosing street drivability??

This topic could be a good starting point for people new to the cars looking for modification but not sure when will power upgrades really start effecting street drivability.

I realise at all power levels it inevitably comes down to the person driving the car and how the car is set. Hearing stories of people cautious not to take their car out in the wet or past 3000 rpm etc etc…. it would be good to create an indicative benchmark.

I think this topic will work best if the boys with the big ponies & tuners who have progressed up the power curve point out where they believe the balance was tipped.

I personally believe XRT’s start loosing drivability some were around the 300-350rwkw’s, this is the time overtaking & driving in the wet start to take some serious thought.

This topic is meant to help people new to the cars & modifying soo could flaming please be left to other topic’s.

Regards

traction control without it even a stock t would be undrivable in the wet

This should make for a very interesting topic - well done.

Let me kick off....................

Although I only drive my car occasionally on weekends (and NEVER in the wet - why dirty it) it really is not something you could live with on a daily basis. Well, you could, as it is smooth and everything but the power is quite brutal and even changing lanes or overtaking you have to be very careful that you don't use a great deal of the pedal on the right.

Normal everyday driveability, I would say a max of around 360rwkw's and definitely an auto. At least you could use most of the power (having decent tyres) and it shouldn't or need not be too loud. You really don't need anything or can use anything more than that for the street. I knew mine was becoming silly, but I didn't build it for everyday use.

I agree with the above power range. As usual, there are a few variables, like driver skill/experience, when the power really comes on, road conditions etc. Overtaking other cars that are doing 100kmh, coming on boost and having the arse end skip out can be fun. But when the wife and kids are in the car, it can be construed as a touch dangerous, especially when she is the pilot, and has very little experience with vehicles that have this amount of power.

Nice topic TUF.

I have just purchased a new XR6T ripcurl ute and was wondeing the same.

I figure when the time comes to play with the stock settings, I wouldn't want to go much more over 300RWKW ( I just have to work out the best way to go about that now) but it will be interesting to see what those who have been there and done that have to say on the subject.

I love the color of the Ripcurl utes.

This is the main point of this topic, 300 rwkw are soo easy to come by.

300rwkw - relatively easy to get these days at a reasonable cost and useable on the street.

350rwkw - still not too hard, especially those with FPV's with bigger intercoolers. Minor hardware upgrades will get you there easily in a T. Still reasonably streetable especially if it is an auto and still reliable.

400rwkw - now you are getting serious and up towards the turbo's max limits. You are pushing the limits of longevity of FPV's bottom ends, autos and fuel systems. You would have upgraded a lot of hardware to get here and to stay here safely! Reliability with standard motors is going to be a concern and useability is a little more of a worry. If you have really good tyres in 275's, it doesn't pose too much of a concern but there is sufficient wheelspin in the lower gears to not go forward as quick anymore. You have to be careful!

450rwkw - you would have done the bottom end and gone to a bigger turbo - fuel systems, clutches, autos everything. This becomes a whole new game. Getting silly to the point of unuseable.

500rwkw - as above but now is really stupid for the street. Absolutely lights the tyres hot or cold in third anywhere, anytime. If they have insufficient heat in them, in will still spin through fourth also. Standard tyres have not a hope in hell of holding traction in fifth either - hot or cold. Trust me, I know and others can vouch for it. This power level is good for scaring passengers and making lots of noise and making yourself laugh from time to time. Dyno comps are okay - gotta strap it down properly though!

500+ rwkw - now this is just plain stupid and dangerous. Good fun but!!!!!!!

Guys I'm getting a little bit off topic here so please feel free to reply via a PM instead of in this thread. Having been there and done that, if I were to give you my new ripcurl ute and told you I wanted 300kw, how would you achieve it ( theoretically of course)? I'm new to all this but from what I can gather the BFII is a lot easier to get this out of.

I'm thinking along the lines of exhaust, CAI, injectors and obviously a tune. Would that get me where I want to be with a reliable, use everyday car? I should mention the ute is a manual so before I let you loose on it I would have had the clutch upgrade done

Sorry for the hijack!

for me, 300rwkw is more then enough at the moment! Driving in the wet, I'm very cautious when overtaking, especially on two way roads. I rarely use boost in the wet, when I do it's only brought on very gradually, and I won't put the foot flat!

In the dry though, it's really a different story, I've basically adapted my driving style to suit. At first it took a little getting used too, as I was still used to just hitting the go pedal.. now I'm more cautious of bumps, dirt, or anything else that may or may not be seen on the road!

It's all about the right foot, and it took me a little while to really figure it out. My advice, to anyone who hasn't had a T with power upgrades before... although it will cost a little more, I'd be more inclined to go in stages.. I'm glad I had 250rwkw before going straight to 300rwkw, and I'm glad I'll have had 300rwkw before my next power upgrade to 350rwkw. There's almost a world of difference between stock-250-300-350 etc etc. Obviously the experienced blokes, who've been there done that, then they can go straight for 500 but for the younger blokes, in hindsight, I'm very thankful I did it in stages... and that's after an accident too.

At the end of the day, it will depend on the driver, and their attitude. I've really calmed down a lot with my car, even when people egg me on, or when I have that Late model camira up my ass. Sure I'll give it a squirt, but I don't think it's worth the life of myself, partner, child or anyone else's. At the end of the day, I'd probably use my cars full power, a few times a month... the potential to lose one's licence is massive.. going WOT to 5000rpm through 3rd or 4th will usually see the speedo go way past the limit.

Enjoy the power, but I've realised I don't need to give it hell everytime I hop in the car... perhaps I'm going soft since my 25th birthday or maybe having a child has softened those hardened habits

cai, injectors, fuel pump, intercooler, tune and hi flow cat should see a comfy 300rwkw, perhaps more
