The GSXR 1000 bike used for the F1 and Senior races is nearly ready. We were hoping to get the new Yosh ems system, but i understand from JeffW that it will not be available in time. So we are going with a PC-3r to get the fuelling right. it is being set up by Hobbsport Racing in Keighley, West Yorks, UK, on their Dyno.
We have recently taken delivery of a QB carbon large capacirty air box to go with the QB carbon 24 litre tank. Once Hobbsport have finished the bike will be race prepped, with virtually everything being lockwired. The only other thing to sort out is the quick release rear wheel system as we will be changing the rear wheel during the F1 and senior races. We have a trick brembo rear caliper and cresent suzuki hanger to install as part of this process. I will post some pics when we have done this. I will also post the dyno chart of the finished bike, once Hobbsport have set it up.....we are hoping for 180 rear wheel bhp
For those that dont know where we are up to with the bike this is the lastest position for the main F1 bike............
The formula 1 GSXR 1000 bike is now almost finished. Just waiting on the PC-3r arriving to go with the QB carbon air box, now that the ems system has been ruled out due to non availablity, then were ready to roll. The bike currently makes 172 rear wheel HP and 94 lb/ft of torque, so it should make about 180 rear wheel HP once the PC3r and air box are added. All the engine work has been done by Hobbsport Racing in Keighley, West Yorkshire, UK, including race wiring loom, kit yoshi 32bit ECU (revs to 13,000), new valves, collets, and springs,Yoshi head Gasket, kent stage 2 cams, fully blueprinted with gas flowed and ported head, 3 angle valve seats, raised compression, manual cam chain tensioner, secondary throttle bodies removed etc. Currently just been set up on the dyno with fuelling tweaks with a Yosh Box, awaiting the PC3r. Now running a set of OZ race wheels as well as a full PFM narrow track superbike conversion brake kit with AP racing adjustable master cylinder and the bike looks STUNNING.
We are running an Ohlins rear unit matched to the new Yosh shock linkage, with Ohlins internals in the front forks which have already been revalved by Ohlins. We also have an Ohlins damper. Still to go on are some Q racing rearsets, race subframe, fairing bracket, clipons etc from steve at www.overthetop.ca .
During the race we will be using Pirelli rear slicks with Pirelli supersorsa fronts. There is probably loads of stuff i have forgotton but will add more when i remember !!!!
We have a Yoshi Tri oval system on the bike and some NRC engine cases
we have also been donated some Promach yokes for the bike, much stronger than stock to cope with the stresses and strains of trying to keep the front wheel on the deck over the bumps on the public roads!
The F1 GSXR 1000 has now been dynod and we are very pleased with the results. It now makes 178 rear wheel horsepower and 98 lb/ft of torque
. When we started out on this project, i bought an ex UK superstock bike and had it dynod at 143 RWHP see graph. There was some wheelspin at peak HP due to a shagged tyre!, hence the squiggly line at the top
We then had all the engine work done and were then awaiting the new yosh EMS system to control the fuelling. in the mean time we had the opportunity to attend the European Superbike school at Jerez in Spain, so the bike was set up with a few fuelling tweaks with the Yosh black box. This gave us 172 RWHP see graph;
Although the bike ran very well, it was very thirsty. We knew we could control this with the yosh EMS, so we were not too bothered. Anyway, the TT was getting nearer and nearer and still no sign of the new 32 bit EMS system, so we had to plump for the Powercommander PC3r. This has now been fitted and the bike fully set up on the Dyno. It now makes a consistant 178 RWHP and 98Lb/ft of torque. See graphs for RWHP and engine HP.
I was hoping for 180 RWHP, on one of the runs, the dyno showed 179.9HP, but all the other runs were consistant at 178/9 with oodles of torque.
A big THANK YOU to Hobbsport racing and a big thanks to Mark (the owner) for sorting the engine and building us a strong and hopefully reliable engine
All the dyno runs were done on the same dyno with the same operator, so apart from weather conditions, which were pretty much the same, everything else was consistant.
the bike feels bloody fast even when on its stands. it revs Sooooooo quickly, more like a 600 than a 1000 and with the new QB carbon air box you can hear the air being drawn into the engine. sounds more raw than before, but you know it means business.
when we were at Jerez, it felt extremely "rideable" if there is such a word. i never felt scared of the bike, like it was some evil beast that was going to spit me off at any point. just very controllable. the front still starts comming up in 4th at about 140 mph though.!
I have got some pics from today, will post shortly. spent all day sorting the bikes, starting to get there now. been trying to sort the gearing on the 1000. with so much torque we have decided to start out running a 17 front and a 40 rear, should be good for nearly 200 mph and help stop wheel spin.
the 600, awaiting the forks returning... with pics of dave the rider at previous TT's on the wall
daves replica trophies from previous years
the QB carbon air box and tank.....
Carbon tank and air ducts, plus promach yokes..
awaiting bodywork for the 1000 and forks for the 750.....
the bodywork for the 1000 is staying in the yellow and black colour scheme as per the previous pictures from Jerez, just got to paint the number boards white for the F1 race. The bodywork for the 750 is still at the painters. will be in metalic blue along with the 600.
i will try and get some more pics later in the week, but we are rushing around now, trying to get everything done. we are on the ferry in 5 days.........
the finish on the air tubes is fantastic and they are top quality. they are from QB carbon in the uk and you cut them to the length required. We cut them slighlty longer than stock for the new air box.
I cannot remeber how much, i think they were about £200, so would be about $300 i am guessing, but i cannot remeber for sure.. much better than the original brittle suzuki ones
