Ferrino Posted August 15, 2004 Share Posted August 15, 2004 Seems that other live-axled BECs are using the Ford axle with a 3.54 diff successfully...... Link to comment Share on other sites More sharing options...
Violet Elizabeth Posted August 15, 2004 Author Share Posted August 15, 2004 Wonder what sort of top speed a 3.54 ratio would give ? Link to comment Share on other sites More sharing options...
Mike Molloy Posted August 15, 2004 Share Posted August 15, 2004 A 3.54 diff would give a Blackbird a top end of about 125mph at the 11250rpm rev limit. IIRC this is the setup used by Barry H.

Violet Elizabeth Posted August 16, 2004 Author Share Posted August 16, 2004 An R1 engine (11000rpm max ?) with a 3.54 ratio on 185/70/13 gives a maximum calculated speed of 128mph in top. Drops to 120mph with 60 profile. My planned GSXR1000 with a 3.27 ratio-ed live axle has a theoretical max of 137mph on my existing 70 profile A021's So thinking about some tyre changes !

Badger Bill Posted August 16, 2004 Share Posted August 16, 2004 Yes, about 120 in 'blade with 3.54 on 185x65x13 a539's. It works out round about 10 mph per 1000rpm, in top. BB Link to comment Share on other sites More sharing options...
barry.h Posted August 16, 2004 Share Posted August 16, 2004 Yes, spot on Mike. In fact 120 mph is a truer figure as 11,250 is somewhat beyond peak power. But it gets there very quickly 😬 😬 😬 Barry Link to comment Share on other sites More sharing options...
Ferrino Posted August 17, 2004 Share Posted August 17, 2004 Can anyone suggest any other places which would be able to fabricate engine mounts and make chassis modifications for an R1/Blade install into a 7? Currently contacting Arch, Stuart Taylor, Kitcarworkshop, Seven Workshop. Any others I could try? Link to comment Share on other sites More sharing options...
Irrelevant Posted August 17, 2004 Share Posted August 17, 2004 Ferrino: You've probably seen this but just incase......FWIW, I'm just going to make a pattern and get some made - try and do as much as I can myself rather than pay £3K or something stupid for the installation. Force Racing will do a full install for £3K, or so I've been told. Accumulating bits . . . Link to comment Share on other sites More sharing options...

Paul Thompson Posted August 17, 2004 Share Posted August 17, 2004 Please can you tell me what is so special about the R1 engine. As a matter of record my Ital axel with slicks has done 4000 track miles running a Fireblade engine - perhaps I drive too slowly Link to comment Share on other sites More sharing options...
Irrelevant Posted August 18, 2004 Share Posted August 18, 2004 Paul Thompson: There's nothing special about the R1 engine other than it makes more power than the Fireblade for not much more weight. From memory, approx std power figures: Fireblade: 135 bhp R1: 160 bhp Hayabusa: 175 bhp There are of course other engines such as the ZX12R, GSX1100R, GSX1400, ST1000 . . . . Accumulating bits . . .

Violet Elizabeth Posted August 18, 2004 Author Share Posted August 18, 2004 And the GSX-R1000 The R1 *is* special in that it is fairly square and upright (pre '04), has a cable clutch, the drive sprocket is fairly central so prop angles are good... and particularly special is a built in oil cooler. It also can get away with not being dry sumped. An all round good egg This months Kit Car magazine has a section on mad BEC's including a 180bhp Gixxer in ...

Ferrino Posted August 18, 2004 Share Posted August 18, 2004 Redlining at 11,750 makes for a beautiful soundtrack 😬. Gear linkage is also in a good position for a BEC. Have seen some good prices for this engine too. No need to dry sump . Link to comment Share on other sites More sharing options...

dogvet Posted August 19, 2004 Share Posted August 19, 2004 I had a Westd1eld blade car IRS, sold on the guy now runs it on slicks (track days) no problem at all. There is a race/road Striker LA out there, hill climbs on standard tyres , track days on slicks with standard honda sump, been in car for 4 years, again no problem. The Stirker will handle as well as a Caterham, and will generate the same forces. It appears with the bike engines under 1000 cc no need to dry sump, over 1000cc more of an issue. Contact Andy Griffiths as he has just built a Busa Caterham which ran rings round the R500evo at Oulton at the Cat CClub day, having said that Andy is a very good driver! Fitting the bike engines into these cars is not difficult as the engines are light and manageable, IRO 60 kgs Link to comment Share on other sites More sharing options...
Violet Elizabeth Posted August 19, 2004 Author Share Posted August 19, 2004 Bit dangerous to invent the GSXR1000 needs a dry-sump. Think the ZX9R does too. Link to comment Share on other sites More sharing options...
Morls Posted August 23, 2004 Share Posted August 23, 2004 A 'Blade engine in my little se7en feels pretty quick, but having ridden my old R1 back-to-back with a friends 98 'Blade, The Yam made the honda feel like a 600, so if the packaging stuff could be sorted an R1 would deffo be the nicer motor. Still very happy with my 'Blade tho, especially since I got sensible (150lb) springs on the front and can go over 90mph without it bouncing off the road. If anyone does get an R1 fitted in their Badgerum, would they please do the decent thing and paint it with a Kenny Roberts 'Yellow with Black squares' paint scheme 😬 Mark Look it's Mavis here and Jubilee 7 here Link to comment Share on other sites More sharing options...
DanB Posted August 24, 2004 Share Posted August 24, 2004 Noger, ZX9R doesn't need a dry sump IMHO. My Striker ZX9R 'pisspot-mobile' with AO21Rs doesn't suffer surge with a wet-sumped ZX9R C2 engine. Dan Link to comment Share on other sites More sharing options...
dave1968 Posted August 24, 2004 Share Posted August 24, 2004 anyone ever heard if anyones stuck a bike Vee Twin engine in a 7? (Ducati 998/ Honda SP2 etc?). Not the ultimate high rev / power but lots of grunt... sorry I know this is probably daft but work is just soooo dull today Link to comment Share on other sites More sharing options...
vinnie m Posted August 24, 2004 Share Posted August 24, 2004 blimey Ducati 998, in a Caterham, mmmm that will be a clutch every 1000 miles then!!!!!! ZX12R seems the best bet from a biker owning Caterham driver point of view type thing! vinnie Blue & Silver Supersport-R Link to comment Share on other sites More sharing options...
Violet Elizabeth Posted August 24, 2004 Author Share Posted August 24, 2004 Not that many ZX12R BECs about, so could get expensive. Sounds fun though. I am not that sure that the V-twin approach is the best thing, lovely though the sound would be. The low-ish RPM and gearing would be mean having to go for quite a long diff ratio, not sure that anything is available for the Live-Axle, would need the Quaife 3.14. With a 3.27 ratio, the max potential speed of an LA 998 on 032R's is 109mph ! Even with the 3.14 it is still only 114mph.

greg Posted August 24, 2004 Share Posted August 24, 2004 Sounds like a fun way to get to 114mph. Following this with interest Noger. Link to comment Share on other sites More sharing options...
Violet Elizabeth Posted August 25, 2004 Author Share Posted August 25, 2004 The noise would be fantastic ... but it is not the fastest way, grunt or no grunt. With the slightly lower bhp at slightly lower rpm, longer internal gearing, and the requirement for a longer diff .... a 2002 998 R powered Quaife de-Dion is 90 ft.lbs (at rougly the same mph) down AT THE WHEELS on a 2002 GSXR1000 powered Live Axle. One day i will get shorter/longer gearing right Edited by - Noger on 25 Aug 2004 10:37:28 Link to comment Share on other sites More sharing options...
