    I took the car to RAF Marham for the 30-130 run by the MLR.

    Now the car quite well to start with...

    Id got the 30-130 time down to 13.5 seconds and a top speed of 166 which is v box timed not speedo (which was off the clock).

    The 166 top speed run had a lot of runway left so I had another few goes starting off with full launch control

    The 30-130 came down to 13.2 which isnt bad for a full weight bus but something gave way at about 150mph filling the entire runway with white smoke

    I drove off the runway toward the pit as at the time I hadnt seen the smoke as the mirrors were shut ( it all helps) . As I slowed down the smoke became obvious so I stopped.
    Suddenly there was then a kingston cop moment as fire engines and marshalls hurtled towards me from every direction after I had stopped on the way back.

    They took a lot of convincing it wasnt on fire or dropping oil
    Because the ashfelt is a special type that absorbs moisture so the planes can land in the wet they are -paranoid about spillage. And it is mega expensive so any fire and the whole car is sprayed.

    Anyway on to the damage ?

    I think it is a piston (at least) The fuel pressure was fine and it had been mapped for the event flat out on boost in all gears is very hard on any engine and my foot had been on the floor for a long time.

    So it looks like there will be a new greanmachine project thread

    Ive discounted breaking it or selling with a stock engine mainly because the rest of the car ran absoluelty spot all day.
    Most impressive was absolutely no judder or at all or movement off the line and at 160+
    The new awd suystem handled the power so well I had no wheelspin even when using the full launch control from standstill on boost

    I also found out what good brakes are . It seemed to stop almost instanly from 160+ with no fade and in a perfectly straight line

    So I just need a motor....

    I have a spare RB26 but it isnt forged so wont take the power of the current turbos and cams.

    For that reason I probably wont use it because I cant see me happily driving it with less power than it has now.


    So the hunt is on to find a suitable engine

    Options are maybe a rb30 short block or there is a virtually new time attack engine for sale on the gtrroc which I know the history and the builder (RB motorsport )Trouble is lots of £££s


    The good news

    A the fastest speed in the world for a gtr was set on saturday 239,1 mph

    The same car also did 30-130 in 4.63 seconds and aside from the first shake down run broke 5 seconds 5 out of the six runs . Only difference was a change of tyres.

    And yes this was a Nissan engine ,yes its overbored , bigger turbos plus a fair bit more. It is road legal but not exactly a good runaround :lol:

    Fastest 30-130 run of the weekend was a scooby on sunday 4.01 , less headwind on the sunday but still mindblowing.

    This scooby is and out and out stripped track car car with NOTHING on the car that isnt needed

    Just to add the 30-130 time are all uphill into a headwind. The runway which is 1.6 miles long levels out halfway.

    I feel your pain sleeper :sad2:

    I really hope that you get a replacement engine soon for the monster :)

    Oh thats a massive shame mate! I hope you get the green machine back on the road soon!

    So with whats happened, have you any reason to rethink anything? Maybe larger turbos? Especially if your trying to source a forged engine?

    That's what i'd call mixed feelings. I feel for you buddy. Hope you get it all sorted out quickly.

    I guess an RB40 is the next engine you'll be creating.... ;)

    The engine was forged
    It was simply flat out for half a mile in top gear on full boost which is a different ball game to a standing quarter or the like .
    And I did it four or five times ,(or was it six :bigsmile: )

    I will probably keep the turbos if they are ok and get some head work done with maybe some nos for santa pod etc

    Looks like the GTR will be coming out more than I had planned

    Treat it with the utmost respect sleeper, that car is truly a valuable classic and totally untouched by a modifiers hands ;)

    Sleeper I too have lost a less than 3000k old forged motor at the track due to a poor /bad dyno tuner so feel for you.
    PS it's "Keystone Cops"

    After further checking it seems that the be st guess isn't a bad map bit a bad right foot.
    The most likely clprit is the cas unit which can fluctuate when flat out for long periods . This only happens on a top speed run so almost impossible to check on a rolling road .
    Any change in timing at that speed can cause det and this could lift the head
    Water goes into the cylinder at full revs hence the serious white smoke . After the run the engine cools down so when started cold the next day there is no smoke

    well I am now a lot poorer but the green bus is happy because he has a new motor.

    I have bought a 2.8 HKS step 2 motor with a special crank , cams , oil pump etc and a fully flowed head
    It will produce between 650 and 850bhp dependand on turbo set up and as all HKS strokers are forged so this should prove indistructable , even for me .

    Current thinking is probably a pair of garrett gt28RSs , better known as disco potatoes which should spool up pretty early and produce circa 700bhp

    plan has changed re turbos

    Current thinking is that it may be better to keep the 2860-5s . On the face of it they will not produce as much power, 630-650 at absolute max which is way less than the motor is capable of.
    But on the plus side they should spool up very quickly with really good torque so the car should be really driveable and I really dont need a lot over 600 very often.

    It is true I have been having therapy .....................

    After 15 sessions I was down to 450 but recently unfortunately I had a relapse and went on a bhp binge and bought the stroker.

    My therapist will no longer see me as I am apparently a hopeless case.

    :lol: You'll have a lot of scope for a power hike should you need it and with the smaller turbo the whole engine should be indestructible (unless you do something silly!)

    Just go with the higher power option, having it there will ease the mind, running short in the future may cause irrepable mental disfunction and you may end up a lunatic for life...

    Ive had some correspondance with a fair few people on the oz stagea forum including someone who has a rb28 with 5s . He has some dyno readings. showing 650 has been acheived so that the way I will go especially as I think my engine spec is a bit higher.

    So keeping the 5s should make close to 650 with really fast spool up and I will then only need to add an inline fuel pump .

    I would only really need(want) more for drag events and things like the 30-130 and this could be acheived by running e85 with a second switchable map which my ecu allows.

    This will also be a much cheaper option than changing the turbos and will cover pay the cost of the second map especially it can be done right after the one it will be having after the build.

    SO all the more for other bits :bigsmile:

    And on that subject i now have a Quaife ATE (tourqu bias) LSD in the front. It works the same way as the diff in an rs focus so should help the handling a fair bit ,

    It is supposed to be indestructible and has a lifetime guarantee .................time will tell .

    The engine is in . A few cosmetic changes (was getting bored with red)
    Just need to make a cosmetic blanking plate to replace the CAS unit.

    An update
    I was a bit worried when the car first started up as it was smoking quite a bit . I know the engine is not the problem but there was a possibility that the turbos had been damaged .
    Fortunately everything is ok in tht department.
    It went to be mapped but the existing tomei fuel pump cant keep up with the new engine on boost. It w as fine at 1bar but at 1.2 the ecu closed things down as the afr ratio wasnt right. At least i know he closed loop system works .
    Current plan is to fit a walbro 450 which can run 700+ bhp which is well above what he turbos can make.

    On the plus side it made around 500bhp at 1 bar so this could be entertaining as he turbos should esily manage 1.7

    I may have to think about buying my own pump at the shelll station at the bottom of my road.

    Sounds like things are moving in the right direction ;)

    The personal pump at Shell sounds like a good idea :)
