Hello all, just wondered what sort of times would you get for 0 to 60, 1/4 mile etc fir a big powered r32 gtr, say 550bhp or 650bhp?

Thanks in advance

 

[Jags]

Dont know specific times but I went out in a 550bhp R32GTR yesterday and it was CRAZY quick. Was fully stripped out and quite lairy.

 

[AlexH]

gotta be in the 10's or atleast very low 11's
as jags said i suppose it will depend on the weight also

it wont be slow anyway thats for sure

Are you talking in the hands of a racing driver, or jo blogs from down the road.

Its all down to the driver...

TRACTION, without that, forget the numbers.

Ditto,

If you talk track racing with a maximum optimized street spec GTR , just take this car as a reference:
http://www.gtr.co.uk/forum/116716-act-r-demo-car-600hp-r32-gtr.html

Did 10"897 for the quarter in december at central circuit (with around 600HP) and Suzuki-san the boss from Act-R did a 2min25secs run on Suzuka last year. The car runs up to 700HP, thought with that power you need further engine cooling upgrades (for endurance) and grip tweaks to get the additional power down (especially out of curves).

And just to give you an idea: The owner of the car tried 10 different suspensions, and each was tested on a racing track, the final setup for Suzuka was on Oehlins and needed tons of laps with the final car mapping, to get the best adjustement out of it . . . . it's fine art.

500whp and 1500kg = 10.5 @ 126mph on a good track, good driver.

I just did a few scenario's with the above calculator and it doesn't seem quite right for some reason, for a start they say WITHOUT driver, how is the car suppose to get down the strip? and what if you have a jocky drive or a sumo wrestler drive, it makes no difference??? I think not.

Using the 240z an example, without driver and 2wd:

Power at Flywheel (BHP) : 1500
Weight without Driver (KG) : 1177
Power to Weight Ratio (BHP Per Ton) : 1294.89
0 - 60 (Secs) : 2.68
0 - 100 (Secs) : 3.44
60 - 100 (Secs) : 0.76
Quarter Mile (Secs) : 8.26
Terminal Speed (MPH) : 180.43
Drag Strip Quarter Mile (Secs) : 8.16
Drag Strip Terminal Speed (MPH) : 182.76

We have run 7.8 @ 177mph so then I reduced bhp to get the mph to what it says and did this:

Power at Flywheel (BHP) : 1400
Weight without Driver (KG) : 1177
Power to Weight Ratio (BHP Per Ton) : 1208.56
0 - 60 (Secs) : 2.68
0 - 100 (Secs) : 3.58
60 - 100 (Secs) : 0.91
Quarter Mile (Secs) : 8.55
Terminal Speed (MPH) : 175.20
Drag Strip Quarter Mile (Secs) : 8.45
Drag Strip Terminal Speed (MPH) : 177.41

Now the mph is correct but the ET is WAY slow and its usually the other way round with anything other than a REALLY well setup drag car, usually you can get pretty good mph which is a good indication of whp but your ET is a few 10ths off.

On the calculator I use, I have compared many cars dyno whp figures with their mph at the strip and its been extreemly accurate, most cars are a few 10ths off on the ET but the better cars are closer to their "ideal ET"

On the calculator I use, if we put in 1200whp and 1277kg (including driver) for the 240z we get an ideal of 7.75 @ 177mph, this seems accurate as the car is pretty well set up, runs on slicks and does mid 1.2 60fts.

If we put the Drag-r's 1740kg and 1100whp it comes out at 8.75 @ 155mph which shows the whp is there but the track/60ft/driver/whatever needs some work as we only did 9.4 @ 155mph.

If we put the Drag-r's info into the above calculator doing it as they ask and it came back with:
Power at Flywheel (BHP) : 1300
Weight without Driver (KG) : 1640
Power to Weight Ratio (BHP Per Ton) : 805.41
0 - 60 (Secs) : 2.73
0 - 100 (Secs) : 4.04
60 - 100 (Secs) : 1.31
Quarter Mile (Secs) : 9.11
Terminal Speed (MPH) : 165.12
Drag Strip Quarter Mile (Secs) : 8.71
Drag Strip Terminal Speed (MPH) : 171.87

There is NO WAY IN HELL the drag-r would run 171mph on a well prepped strip even on slicks.

Then compare that to the same internet calculator with the 240z:
With the Drag-r at 100hp LESS and around 450kg HEAVIER it says it should run only 6mph slower??????? WTF????

Something aint right with that but its all very interesting indeed.

 

[Moff]

Does the calculator take into account gear ratios ?

 

[R.I.P.S NZ]

No, mine its been based on years and years of data from very good street/drag to almost pro type cars thats why the average street car will see mph based on whp but not usually get close to the ideal ET.

The calculator in the link above seems quite a way off and the MPH is way too high for the ET in the scenario's I tried.

Maybe I should go through and do up a chart with weight in 50kg increments and whp in 50hp increments, you'll be surprised how accurate it is, your mph will usually be pretty bang on for whp and it will tell you the ET you can expect with ALOT of practise in a well set up car run on a good track.

in my previous setup, in an r32gtr with mickey thompsons i ran an 11.15 with 1.51 60footer.

i left it in 3rd gear across the line & it was on the limiter for a good 1/2 sec, it should have cracked a 10! i didnt get a chance to run it again.

with hks gtss setup on a stock rb26 & baby cams (making 312awkw)

 

[R.I.P.S NZ]

415whp and say 1550kg with driver works out to be 11.2 @ 118mph so my guess is either your car was lighter than 1550kg or you had more than 415whp, I presume your mph was higher than 118?

Rob

its the standard weight r32 with the quoted power, mph was 129.75, my 60' was good.

i guess im not a bad driver

what 60' do u get in the dato rob?

 

[R.I.P.S NZ]

I usually ran mid 1.2s to 1.30s.

129mph in 1550kg needs a minimum of 550whp and the ET could get as low as 10.3 with a real good 60ft, real good driving, good strip etc.

1450kg and 129mph = 520whp
1350kg and 129mph = 495whp

I had a skyline a few years ago which ran 10.2 and it ran 134mph off mid 1.4 60fts, weight around 1500kg and it was around 600whp so you must have a VERY light car or more power than you thought as your mph is a long way off what is normal for a full weight 32 with the power you quoted.

I've done a large chart with 300whp to 1200whp and weight from 1100kg to 1800kg, I'll post it up tomorrow.

i ran at eastern creek raceway, aka WSID.

my error, it made 322.5kw at all 4's which is about 360rwkw on the same dyno.

i'd like to see ur drag graph, that would be good.

did u hear about mark berrys hi octane r32gtr circuit car, reeled off a 9.78 pass on 420awkw! gtr's here in aust we run like stoonk c*nts HAHA

 

[R.I.P.S NZ]

Yeah, your Aussie strips are WAY better than any in NZ and probably pretty much anywhere outside the US.

The 7 second guys here run around 3-4 10ths quicker in Aussie due to leaving harder and being able to make it stick with alot more power.

Rob

 

[R.I.P.S NZ]

These figures are based on a well setup car on a good track with a good driver.
Most will get very close to their MPH based on the whp they have but its very common for street cars to be around 0.5 to 0.8 seconds off the ideal ET, this is due to slow 60ft times and not so quick gear changes.

A good car on slicks will be pretty bang on for both MPH and ET.

[Marko R1]

ok - with my new setup making 600whp, as per your graph i will do a 10.1 pass (based on 1550kg, so i averaged the time between 1500-1600kg)

take off this a conservative .3 sec = 9.8 pass

your graph seems accurate based on hi octanes gtr rob

 

[R.I.P.S NZ]

Cool, glad it works out right for Hi-octiane too, good car, good driver, good track.

Weight V mph is an incredibly accurate way to determine whp, if you don't run the mph on a clean pass relative to your weight, you aint got the whp, simple.
