R33 into the 12's

[Guest Robo's]

Thats a much nicer curve

[predator]

Mine *should* have all the go-fast bits needed for a low 13sec.. and I just got a HKS camgear put in and nice tune-up and its feeling quicker than ever. I find that after the camgear it spins up a fair bit quicker to redline so was worthwhile.

So will see what i can do in a week or two Poor tyres will be thing holding me back i think.

Yours is a top effort though.. no gas, no slicks!

Yeah, cheers Its quite funny, because I'm (obviously) really stoked and I was talking to someone recently who realised what my new power figure was and didn't see why I was quite so happy. The power figure is good, but getting up and going - and pulling through the midrange is meaty as anything. Feels like the 2.5turbo has been pulled and a big NA motor that revs to 7000rpm has been put in, 10-11psi is being reached by 2400rpm (lower than I expected - not sure what normal is). The area beneath the curve makes it feel to me like an all around much faster car, and just more pleasant to potter around in too

I definately rate dyno tuning as a very important step - even without trying it at the strip... its obviously made the car more responsive etc, which has to be worth something in practical terms.

Dyno tuning is great, the only way to go. We played around with the boost settings on mine and tried to get the A/F ratios spot on. Also had a problem with spark too. Once you experience it, you get a picture of how the car performs and everything works together. Still mine is not 100% running correctly, but im not going to get this without a proper tuning tool.

What computer you got?

[deano_82]

i have a 4 door with full 3" crpy cat in place bleed valve running 10.5 psi

soon to have fmic and safc and sedans are 70kgs lighter plus i am doing 100k service soon so i mayswell do the cam gear at the same time, hopefully should be around that mark havnt had it down the strip yet.

i only made 195.5 rwhp with boost and exh oh and filter so hoping to get some decent hp after i/c gear safc and 100k service.

Yeah, it was great having an exhaust probe in there tracking things - and spotted some shady boost behaviour etc. It lays everything out on the table for you.

I'm just using an S-AFC2

[Guest Robo's]

Yeah its great, as soon as we started to boost mine up, it started to splutter. So out come the plugs for some smaller gaps. Fired it back up and no misses. Even tried to boost it further, it read 14.7psi on the dyno print out, shot out 216rwkw, but it had more ups and downs than a rollercoaster. So pulled it back to 13.3psi and it was nice and smooth, made a little less up top for about 500rpm , but mid range was much better.

[ferni]

No slicks here bro

Adrian

But was your 12 with NOS?

[Merli]

very nice, gotta be happy with that... glad you didn't resort to using NOS

But was your 12 with NOS?

Both your posts in this thread have been questioning the validity of nitrous.

You sound like the V8 Brigade 20 years ago when they bagged turbochargers and any form of forced induction and labelled it cheating

Nitrous is a power adder, just like turbo or supercharging. Sure, it had a more limited application, but why does that make it cheating? All you're doing is squeezing more oxygen into the combustion cylinders, exactly what a turbocharger does. Who cares whether it's because a turbine is forcing it in, or a bottle is forcing it in? It's all just oxygen.

Get with the times. No-one cares whether you used nitrous or not. All that matters at the end of the day is that they're running 10s, and you're running 11s.

[2rismo]

11's with gas ya goose :-D

I have developed a dickhead filter that gets rid of all the anti-nitrous, anti-thinking crap that goes on in peoples tiny minds so stuff like that is really water off a duck's back. Doesn't really phase me and i no longer take it personally.

Just to shut some people up though, I am racing with some of the other guys at WSID on the 30th of this month. The plan? No gas, standard turbo, 1.0bar, 12.6 ET @ approx 108mph.

Then you can all LICK MY SWEATY 11 SECOND BALLSACK!!!

[strutto]

and sedans are 70kgs lighter

Negative...

[BOOSTD]

One person does it, then two, then people realise that it is FAR from impossible and all of a sudden everyone is doing it.

Just another barrier utterley smashed by half a dozen 33 gtst's.  Well done mate.

Adrian

I wonder who was the first...

[2rismo]

Absolutely no idea whatsoever.

Adrian

[ferni]

Maybe I am old fashioned (at 23 years young), but with NOS you can sit there all day running the same time, after x amount of runs you will run out, and need to refill the bottle... relational to consistency if you ask me.

I don't disagree with NOS, I just think it is should be treated separate all together... its non street legal, same as slicks etc...

The only time you can use it, is on the 1/4 mile strip.... (same with slicks) you are changing your car from being a street car to a non-legal street car - and in doing that you are putting yourself up against all the other non-legal street cars, which run much quicker cars.

I'm not big into the drag scene, so all this speaking is probably coming from inexperience (but it is all my opinion after all... we are all allowed those right?) I do want to get down to the strip and see what I can run (I believe it does take more skill than what it looks like), but I’m more interested in doing it on full street trim, so I know how quick my car is, all the time, not if I put slicks on, take out the spare tyre, etc...

I believe the race track is a better indication of how good a cars performance is (all round) NOS isn't much good on there.... I have mates in their LS1s which are quick.... in a straight line only...

The times 2rismo is running are better than I could do in my GTR (current state), and the times you will do merli will probably be better than I’ll ever get to... just opinion/thoughts.... I know I’m not alone in this thinking.

PS 12.6, no nos, standard turbo - that's impressive, must be some driving skills there

[deano_82]

Absolutely no idea whatsoever.

Adrian

why do i have idea whatsoever, because i said that sedans are lighter? well dont coupes weigh 1360-1370 and why is it that my car weighs 1300!!!

[predator]

erm - ferni.. but legally just changing your stock airbox to a pod in some states may be "illegal" and "non street legal". Its a bit silly to classify it like that.

I find it hard at the drag strip to "feel" the car as much with the helmet on.. to know what its doing, to tell if its even really if its spinning the wheels. On the street you'd tell straight away and back off, but when you're relying a lot more on instinct and practice its like a very closed environment. So it does take good practice to get it right i think in the full dragstrip environment (helmet on, etc)

[2rismo]

deano, i was reffering to the question from BOOSTD about who was first to run 12.x on std turbo. I have absolutely no idea. Get it?

And ferni, if I run my car without gas, with my spare in the boot etc but still have an externally venting BOV, is it in street legal trim? Very poor effort in classification, dude.

Thanks but I'll let you know if I do it or not. I have run 12.6 @ the same mph as I run "no-gas" but as the WOT switch was playing up and i had it armed with the intention of using it, I wont claim it till i've done it - a problem that is rife on this forum.

[R33vit]

The trick is to get your 60' times down first. Adding NOS means SFA if you spin you wheels like crazy comming out of the hole.

Have a look at all the guys who have done it and pay attention to there 60's

What, like Brett? 11.7 is still a'kickin!
