what is the top speed?

 

arnt they restricted to 150 ish?

 

if so whats the top speed when de-restricted?

and how do u go about doing it?

restricted to 155, derestrict and 170+ no probs

unless you're called Mac 1, then only God know yours topspeed lol

y poor zed is derestricted to 130mph. When it those hit this speed its at low revsand then shuts the power off till it goes belowand then revs up again really need to get it removed.

my poor z is restricted to 130 mph. when i reach this speed the revs seem low but the engine power seem to cut out until the revs drop to a certain level and then it picks up again. i really need to get the limiter removed..

 

 

HTH

 

GAZ ;)

glad you understood :cool:

Unless his gearbox has been modified, it will be 186mph at red line.

My redline is now 8200;)

Theoretical speed of 211mph then. But I think the gearbox would blow up before then. It would be producing massive heat spinning that fast. :confused:

OK ONCE RUN IN WHATS YOUR ESTIMATE TOP SPEED MAC...

FECKIN FAST IS NOT AN ANSWER LOL

 

to slow! :(

The JUN car used a stock box & hit 262mph!

i really dont think a couple of 200mph+ runs is gonna be too much trouble, its not tho it gonna be a sustained speed over hours or so

All I want to do is break the 200mph mark will be keeping every thing crossed.

Jun did not use a stock box. They used a stock crank.

260mph is possible on a stock box, but the engine would bet turning at over 10,000rpm, and considering the box is only good for 600-650bhp and the bonneville one was over 1000bhp

Mac if yer gonna try and break 200mph take a crash helmet and a new set of underwear mate !! :D :D

My 300ZXTwinTurbo with 340bhp and manual box has shown an indicated 270kmh = 168mph on the derestricted german autobahn and that still wasn't maxed out.

 

I was cruising for miles at 155mph. Passed a 911GT3 and that upset him so much he just had to speed up and pass me – just before his turn-off! I just let him or he would have had sleepless nights... :))

You can borrow mine then Mac.

Maybe the engine and aerodynamics will do it but the Trust car suffered double front tyre failure when it was doing 211mph in the US way back in the day. I have the article somewhere. If you plan on doing it get some serious boots on it as at those speeds tyre / wheel failure becomes the main factor

Listers,

 

Managed to find the article re: 1991 Bonneville top speed challenge

(jap tuning houses introduce themselves to america)

 

Turbo magazine January 1992.........(note I did some editing to make different sections of the article - was about more than 300's - hang together but all the numbers and specs are bang on.)

 

The 2 Trust cars ran stock blocks std body, std spoiler, std wheels

 

car 1 reffered to as the dark blue car ran a stock 2.9 litre block, and completely stock bottom end, rods and pistons!!!! :bow: It had trust headers,exhaust, intercoolers and turbos. Fuelling was via a single bank of six 720cc injectors. Power was quoted as 'around 800hp' but unfortunately as the car approached 230mph it suffered a simultaneous failure of both front tyres (even though z rated 200mph+) This car is labelled as trusts high tune road car !!! spec.

 

car 2 refered to as the light blue car ran a stock block bored out to 3.096 litre, heat treated std crank, forged crower rods and forged pistons, trust headers, exhaust,turbos,wastegates, intercoolers and fuel injection computer pumping the juice through two banks of injectors six 550cc main and six 370cc secondary. Power is quoted as 'in the range of 830hp and posted a 246.642 one way :bow: but failed to make the return due to a toasted turbo. :( Labelled as a development version of the high tune road car spec brought over to test reliability. Both cars were there to demo performance gains achievable using off-the-shelf items........... :bow: On the other hand

 

The Jun / Blitz car :bow: :bow: :bow:

Jun / Blitz was using a full nissan race engine, :bow: trick aerodynamics but stock spoiler. It posted a two way average of 260.932 mph :shock:

Under the hood where some very trick items:- Special Air plenum, very large KKK turbos and a fully set up race machine pit crew complete with EPROM burner to do the maps

 

To put all that in full perspective it was 14 years ago and a fully tuned 5.0 litre V12 ferrari testarossa owner was left feeling very sour when his Colani-Strasburg tuned exotic only managed 230mph :tongue:
