If the skyliners could post what revs they were at when they hit their top speed that would be interesting...

Ronnie? Glen? Rupert? Dirk? Mike Smith? Henry?

Rob

P.S. THAT'S PRETTY DAMN IMPRESSIVE!!! :D

I think Rupert had a few thousand revs left as well, so given a long enough runway 200mph could be on the cards ....

Speed

I doubt any of the GTRs had reached maximum speed in that distance, most would have a bit more to go.

Hi Rob

I was hitting approx 8-8,500 rpm in 4th gear using the 33 box in me 34. Talk about long geared :D :D .

I've got to get it on a longer airfield to see what it'll do ;) .

Speed

My speedo showed 190 or at least where 190 would be, its about a 10th of the way through the odometer screen! Goes to show how far out speedos can be as long as the gear used as Elvington was really accurate as well, I did 178 on the timing gear but showed 190, speedo's lose thier accuracy the faster you go hence the variation especially as the speedo is converted using an aftermarket CKDR.

I think I was at about 7400ish RPM, maybe a little more, cant really remember very well so 8500rpm on the limiter should be interesting as I dont know about anyone else, I had bags of power left, car was still pulling at 178, needed more road OR more power to get there quicker which is the name of the game at those speeds.

Speedo

Yes, A lot of them are out by a large degree.

I had previously calibrated mine with GPS on a dual carriageway, when it said 180mph on the speedo, it was 180mph on GPS, both were held for a steady mile.

In Germany we had problems with GPS, mine only read 184mph when the speedo said 200mph, whereas later DCDs read 199mph, when we were doing slightly less. I think the GPS we have is not designed for very highspeeds that are changing.

Hence why I say 'circa 200mph', since we do not know.

However, the car was pulling well above 8000rpm in 6th, I don't know exactly since I was watching the road not the rev-counter, which was just as well when someone pulled out in front of us at 195mph - ask Mark, or Warren what the language in the car was!

That'll keep you busy for a little while.

Cells to 'edit' are not 'locked'
Edit the cells in 'blue' with ur chosen ratio's.etc.
Enter combination's for any 4,5 or six speed car.

u can work out the

Displacement
Bhp/Tonne
Torque/Tonne
Bhp/Ton
Bhp/Litre
Weight Distribution Front/Rear
Tyre Diameter
Mph @ any Rpm u choose in said gears
Even reverse gear
Rev Drop chart so u see how much revs u drop when u change gear.
And at Mph how much Rpm u use in 1 to 6th gears.

Damn

That sounds technical.

Rob. My 34 had given up 3rd gear around March this year but I kept it in until a couple of weeks ago. 33 box was a much cheaper option than another 6speed. Managed Germany etc., with the 34 box but was no good for launches.

Wow seems like I was the first in the UK to break a 34 box :( .

Glen...

Open the Skyline_5_speed chart and change the 'differential ratio' value from 4.111 to 3.545. That'll give you the speeds for a '33 box with '34 diff.

Glen,

May I ask how much power your 34 was pushing when you broke the 3rd gear? How did you break the gear......were you launching the car hard from a dead stop or just pushing hard at high speed?

I like to know because I can't afford a hollinger/sequential box :p

Thank you in advance ;)

Hi Keith,

I was well chuffed with my top speed, I still had my rear wing on so may have gone even faster without it.

My power output i'm not sure about, at 1 rr session I had 515bhp at 1.15bar then at the next with the same boost only 474bhp. I was running at 1.35bar on the run so could be anywhere between 500-540bhp I guess.

Full spec on my website but basically usual induction bits with Intercooler, HKS2530 turbos, PowerFC and 600cc inj. Still running completely stock engine internals including stock head gasket and cams (done over 50k).

I'll get the vid clips from the runs up on my site once my home pc gets going again, should be next week sometime.

Cheers,
Mike
