2RISMO smashes into the 12's

[benm]

Nice work Adrian, I had people looking at me all funny when I was cheering from behind the pit wall when you did that 12.5sec @ 116mph...

Now... back to finding where I can gain 0.7sec in my car without replacing the driver

Nice one dude. When in doubt, put your right foot out

2rismo

what power do u think u r making to run that time?

240kw@wheels??

[benm]

it wouldn't be far off it...

[BU5TER]

going off the mph and 60ft he'd have 260ishrwkw maybe even a touch more

[R33vit]

Well done Man.

I missed your run (was still waiting to be scrutineered)

[RNS11Z]

116mph as buster said is around 260rwkw`ish.

congrats on the time 2rismo with slicks you should be able to get very close to a 11. good luck

nicknick i went 12.601 @ 120mph with an rb25 and t88 - running only 345rwhp. i dont mean to be rude but your time with c16 isnt impressive - sure its quick but not for the mods its got. the mph suggest you have around 300kw's. good luck with it though

[whatsisname]

Yeah I was thinking Adrian would've had around 260-270rwkw. I've had slightly higher mph and similiar rwkw.

Nitrous is bloody impressive stuff! A 50hp shot gives a HUGE improvement.

[wreckedhead]

the mph means nothing, i have dyno sheets on over 400 rwkw if you want to have a look, with an 8 grand launch i had so much wheel spin i couldnt keep traction, and with the clutch slipping in third gear im impressed that it held at all after that launch. but anyways the new clutch is going in this week so next week hopefully will run a beter time, i was also unimpressed with my time, but then again i needed a bad time so i can beat it this week.

i ran a 11.8 @ 124 mph and 11.6 @ 120mph. prooving mph means nothing when it comes to the quatre. anyways i wont know what happends till next week. will run it on pulp next week just so i know what its cappable of doing on the road not just the creek.

Dyno sheets mean nothing, quarter mile times and mph dont lie.

[benm]

Dyno sheets mean nothing, quarter mile times and mph dont lie.

...however 1/4 Mile has a lot more to do with the driver than a Dyno does. My 60ft and TS time/speed show using data from 80 1/4 times on my website) that my car is 'capable' of a 13.8sec although im still hovering around 14.1's so how is that an accurate record of the power my car is making when my 1/4 time is slower than what it should be? (i'm lacking mid-top end).

[wreckedhead]

do i get added to http://skylines.pnc.com.au with my times maybe.

[2rismo]

wreckedhead,

saying that mph means nothing in quarter mile drag racing is about the least correct thing i have ever heard said on the subject.

thousands of drag racers for about 100 years would beg to differ.

dyno sheets mean ABSOLUTELY NOTHING!

To answer the previous question, i will speculate that the car is making about 250-260kW @ the wheels. Will check this in the coming weeks.

A real world drag strip MPH figure is a faaar bigger indicator of performance potential than any dyno number. So yeah, couldn't agree with you more Adrian.

I ran 13.0 @ a best of 115.8mph (2.2-2.3 60ft from memory) with ~260rwkw.

[RB20LagWagon]

Unless you cant keep your foot buried to the floor and change gears swiftly, then mph will be a good indication of potential, of course when you get the quality run your mph will increase, but not significantly, Oftens its found that mph drops slightly when you run that perfect run due to lack of wheel spin

[2rismo]

RB20LagWagon - Couldn't agree more.

My highest ever mph is 116.10. Combined with a 2.294 60', this gave me an ET of 12.970

With a lower mph of 115.45 and a much better 60' time of 2.001, I ran a 12.585.

So if u r making 250kw@wheels have u upgraded your fuel system?

My limited understanding of NOS is they it speeds up the combustion process by helping burn more air and fuel than normal hence creating more power.

So using NOS still means u need to upgrade fuel system and clutch atleast.

NOS also puts the same stresses on the engine as a big wack of boost from a bigger than stock turbo?

Fuel pump is a Bosch unit but not running any more pressure than std (std reg still in place etc). Extra fuel for the extra oxygen to burn is injected through the same nozzle in the inlet. Nothing extra req'd from the injectors.

My limited understanding of NOS is they it speeds up the combustion process by helping burn more air and fuel than normal hence creating more power.

Adding Nitrous Oxide (N20) increases dramatically the amount of oxygen in the combustion chamber that is available to burn extra fuel. Remember, you dont make more power with JUST more oxygen.

So using NOS still means u need to upgrade fuel system and clutch atleast.

What?>?!?!?! No. Clutch? Where'd that come from?

NOS also puts the same stresses on the engine as a big wack of boost from a bigger than stock turbo?

Almost, yes. Using N2O also dramatically increases combustion chamber temps, prob by more that upping the boost on a turbo (generally) so technically the motor is more prone to detonation.

I was saying that u need to upgrade driveline components if u r using NOS and that it not just a matter of getting a stock car and adding nos and then running 12's as some people might think

[2rismo]

I don't reckon anyone reading this thinks you could do that.
