Benm,

 

So the R33 N/A ~150kw will crack 250km/h.. :D

 

I don't think it would. :P

I am unsure about the N/A but I can assure you that a 250hp (186rwkw) RB25DET is very capable of pulling 250km/h (and still pulling beyond that altho quickly running out of rpm before the rev limiter).

Lets just say I have a friend that has a flat private driveway to his house/property with plenty of run-off room where hitting 250+ in an RB25DET is very achievable.

Benm,

well I know I also took a stock pulsar over 200 with

but I think things get much harder over 200, thats a lot of air to push out of the way.

A dyno can only tell you the wheel speed of the car at the rev limit in 5th, there is no way you can max out a standard car no matter how long the road

uh?

I agree with Bazelinez, the speedo and real world speed do tend to be out slightly. I know on the private road i use, my PFC reads 180 as my speedo nudges the little "HICAS" light off the end of my 180km/h stock speedo. at 200km/h on the PFC, the needle was just past the HICAS light. :P

well thats an interesting question.....personally I'm surprised a PowerFC would read different to a speedo since they both use the same sensor in the gearbox :confused: I think the main issue is the rolling diameter not being exactly right for the speedo

IMHO GPS or good accelerometers are the only accurate way

Benm,

I miss-understood you. :D

...and im saying you dont even need 250hp to crack 250km/h (and you dont even need 7,000+ rpm).

You then said your friend with a Rb25DET (which is 250hp) cracked 250km/h.

The N/A won't cut it. 250km/h is just too much air to push out the road.

This friends R33.. Was it dead stock? or had the usual exhaust?

How did it go towards around 235-250km/h. Torque would have been dropping off at that point so I would have to assume the last 10km/h were slowish.

Pulling hard is subjective.

Honestly, I really do find it hard to believe a stock R33 (including ride height) would zip up to 250km/h without a struggle, think it would really be pushed to get there.

But its all I think. :D

I believe 230km/h is a fairly easy target but after that things slow down quite a lot and takes quite a bit more time to get there.

Well if a little old corolla can do 8500rpm in 5th (3SGTE, but pretty much stock) then I think a skyline could do better.

BTW, working it back and allowing for the speedo being out, the rolla was doing anywhere from 270kmh+ (sits on about 2800rpm in 5th at 100kmh, but we know its more like 90kmh. So if anyone wants to do the maths)

I have some bits to add to this all done in safety offcourse. I have an apexi digital speedo for my r33 with some small mods to the car. At about 100 on the standard clock but the apexi is reading 105 and the gap increaces slightly the faster I go, but the top speed i have done in safe envronment was 260 on the apexi.

    • Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA
    • All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.      
    • roller coaster of a ride. Alarm system was removed & main harness was repaired where possible. still no fix just random successful starts. moved on to the replacing the ignition switch and relay. well all this troubleshooting & repair has been going on, the car is at a paint and body shop being pushed around. Ive been going down there on odd days after work to get it sorted.     
    • 5th November if you want to come out for a spin wakfield
