i guys my name is scott berry I aquired a global gt last year with the intention of doing a few run what ya brungs with it and a few trackdays. So after doing a few little jobs I fianly managed to get the car up to santa pod and have a few runs.It didn't quite go as planned but thankfully no major dramas but that was to be expected. I managed to do a run of 12.7 on a set of old scrubed wets bellow are some pictures video and times. If anyone has any advice or suggestions on how I can improve these times please post them as I think I am addicted now

its a global gt light.Made for a one make series that still runs in ireland.The car is runnig a 1999 yammaha r1 engine.The engine is fairly standard as far as i am aware the only modifications are a k+n air filter,omex rev limiter and smaller sprockets.These cars run a chain drive system were the engine cradle is moved to tension the chain.As for the suspension it is a full inboard setup with double wishbones large ohlins shocks all round with ajustabel dampening.The chasis is a tubular spaceframe.Fully fueld with me in it weighs about 480kgs.I think the first upgrade will be an uprated clutch.Other than changing the tyres the suspension has been full setup by aurock wich is handy because the previous owner is about the same weight and build as me

i dont think it would fit inside the spaceframe its fairly cramped in there i think i want to keep with the current engine as there relativley cheaply and car engines are heavy in comparison and probally more expensive to tune
here is a picture of the engine bay

love the photo centeral

tet the roll hoop is currently msa logbooked for hill climbing so hopefully it should be okay.

justin i have a set of slicks ready to go on next time.As for the stiffening the rear its not really an option.I am currently looking into fitting a flatshifter as well.

been reading up on barnett racing clutches.im going to order one of these

i have been recomended to use standerd friction plates thoe does that sound right to you turn 7?

[metro1]

rev limit is 11,500 rpm, im currently looking for a spare engine to rebuild.

it went pop yesterday nocked 500ths of my best time before hand so im hopping to have a new engine put in and be back out within the month there was definatly more performance there

[metro1]

were not 100% yet but we suspect one of the shells has gone but it could be anything in the bottom end im hopping to strip it down and take a look in the week if i get chance. i may have found a new one so hopefully i can swap them round and be back up and running within the month.

yeah i put new oil in before the first trip to the pod hasn't done much inbetween.The oil was genuine yammaha stuff from a main dealer.

hi guys its been a very long time since I last posted but I have now begun making headway with the global and im hoping to take her out again next month. I have fitted a new r1 engine with uprated carbs and a better induction set up, heat wrapped the exhaust and had the front clamshell repaired and re sprayed along with getting a couple of sponsors. I have come to the conclusion that I want to fit a bigger bike engine either a hayabusa or a zx1400 but I am unsure of which and im still working out the details of what would need changing to make the project work however my target is clear a 10 second pass it was something me and my granddad wanted to do sadly he's no longer with me which is why I am more determined than ever to do it. that with said I have just hit my first theoretical hurdle to get to my target I was planning on using forced induction but to get the most out of it I am going to need to drop the compression ratio down which will mean new pistons and rods so how would you guys recommend I run in the new engine? so how do you run in a drag engine?

been a long time since I posted anything but to be honest I haven't made any real progress, the car has been rather unreliable. every time I have fixed a problem I have found another mainly electrical but I have not managed a single pass this year. Things are on the up though, I had a passenger ride in an ab performance arion at sneterton last week, to see if I thought the engine would be a good fit for my project. So ever next month or the month after the car is going in to have an 09 cbr engine fitted. After mapping on a stand alone ecu I am hopping for about 180bhp.In between repairs the car has already been converted to a cable gear change and had a rear wing delete kit made up so I can run without a rear wing while keeping the rear clamshell attached
the jobs that are going to get done all being well are
hard mounting the cbr1000rr engine
custom manifold
rear axle mods
complete re wire
new water pump
removable bulkhead
cut down fuel tank and modify into twin tanks so I have a 5 litre drag tank and a 20 litre circuit tank to reduce weight

haven't spoken to a scruitineer yet as i'm trying to keep it fun and get the thing reliable as for wheel spin I don't have that trouble at the moment but I have shredded one chain so far. I don't think it was that great to begin with but I have managed to blag a new renthal chain to try for free and I am looking for a used set of slicks on rims for the front the main problem I have is that without reliable seat time I cant progress and I cant get that without reliability which just isn't there
