Pat the Plumber Posted July 30, 2008 Share Posted July 30, 2008 didn't Mike do 161mph a short while ago at another air strip. don't qoute me on this, i'm sure he said it would still do more if he had more road to keep going, or bigger b@lls, not sure which would apply more. interesting that Rob's only does 137mph with 260bhp, mine's on the rev limiter at the same speed. Duratec is the way forward!! Here Link to comment Share on other sites More sharing options...
Mike Biddle Posted July 31, 2008 Share Posted July 31, 2008 Pat, yes I did, at Brize Norton, 161 on the satnav. I think it would do more given a longer run, maybe up to 165, must give it a go someday somewhere very quiet, early in the morning on a Sunday perhaps. The Levante would probably get somehere near it if it wasn't limited to 150. It obiously has alot more power than my car and has better gearing since it's running 15" wheels as opposed to my 13" IF, my car had enough power the rev limiter would come in at approx 195.

rgrigsby Posted July 31, 2008 Share Posted July 31, 2008 Pat mines gearing limited to 137mph, it would easily go faster with bigger tyres or longer gearing, as demonstrated by the fact that I could lift of WOT at 137mph and still stay at that speed. I suspect it will easily do 150mph with the right gearing, maybe a bit more. Cheers Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...
Claire Voyant Posted July 31, 2008 Share Posted July 31, 2008 what about one of those lovely 7's with an 11 type ali body on it Fails to remain a Seven - becomes an imitation 11 or something similar to a 21 and Adam insists that that is not a 7.

Area Representative Golf Juliet Tango Posted July 31, 2008 Area Representative Share Posted July 31, 2008 Fair enough Adam but that makes Iain correct in that a Seven with an aero body becomes something else.

Irrelevant Posted July 31, 2008 Share Posted July 31, 2008 GJT: A 21 is not a 7 with an aero body - the car's totally different. True, some parts are common and many parts are similar - but it's still a different car You can take an aero body off a 7 and it's still a 7. If you take the body off a 21 you're not left with a 7.

Area Representative Golf Juliet Tango Posted July 31, 2008 Area Representative Share Posted July 31, 2008 Adam Remember that I own a 21 - I know how different it is, so we are in complete agreement there. I doubt you can create an aero-kit Seven without loosing the "Seven-ness" of it - what remains under the body kit? Democratic dissent is not disloyalty, it is a positive civic duty.

Irrelevant Posted July 31, 2008 Share Posted July 31, 2008 I doubt you can create an aero-kit Seven without loosing the "Seven-ness" of it I don't know . . .. I'm thinking bolt on stuff, not a complete enclosed body, e.g. 1. Longer nose with smaller air intake 2. Faired in skinny front wheels with integrated fenders 3. No screen/mirrors/lights, a rigid driver's half door and a hard passenger tonneau 4. No cage, just a small hoop behind the driver's head 5. Skinnyish rear wheels and spats with bolt on side pods to cleave the air past the rear wings (which would have holes or louvres in the back of them). 6. Rigid boot cover with a spoiler extending over the rear to reduce turbulence 7. A rear diffuser to aid air flow under the car (works with the extended boot cover) 8. Fully panelled underbelly 9. Inboard front suspension (not much gain) 10. Aero wishbones (even less gain) That's all pretty standard stuff - it's all been used since the 1920s. So you basically end up with a salt-flats looking 7, but still very much a 7. Bung a big engine in that and with the correct gearing, I reckon it might go 200mph given a long enough run. It might not even need that much power. Link to comment Share on other sites More sharing options...
Claire Voyant Posted July 31, 2008 Share Posted July 31, 2008 Butting in. Sounds like that eco/high mileage version here which was made specially a while back (with a big engine) Edited by - Rollbar on 31 Jul 2008 21:02:38 Link to comment Share on other sites More sharing options...
Irrelevant Posted July 31, 2008 Share Posted July 31, 2008 Rollbar: Chuck an Levante engine in that and gear it correctly and I reckon it would have a good chance at 200mph if the tyres didn't explode. Did they test that in a wind tunnel? Any performance details? They'll be ecomony based ones I assume, but it might be possible to do some whizzo maths type stuff and work out what power it would need to do 200mph.

Area Representative Golf Juliet Tango Posted September 12, 2008 Area Representative Share Posted September 12, 2008 BTTT because I spent an entire working day looking after a sound system which nobody used and this topic popped into my otherwise empty head... 😳 Has anyone tested the difference which the existing, easily attached bits make? I want quantifiable data not subjective opinion. So has anyone taken their car out (say around a circuit) in "standard" form then swapped screen for aero, added a rear diffuser and a rigid tonneau then redriven and compared the performance? Similarly has anyone compared the influence of the front suspension components and/or winglets? Surely Caterham Cars have some data on the influence of the CSR winglets? Looking at Adam's list, I suppose you could compare with and without the underskin as well. Democratic dissent is not disloyalty, it is a positive civic duty.

David Lynch Posted September 12, 2008 Share Posted September 12, 2008 I've ran ¼ mile drag strip with and without windscreen (before i bought an Aero). Worth about 0.9 seconds in a lowly 1.4K 5 speed Couldn't dip below 15 with it on, Ran 14.1 without it !!!

Area Representative Golf Juliet Tango Posted September 13, 2008 Area Representative Share Posted September 13, 2008 David 6 to 7% improvement - not bad. Don't worry about your power - it's comparative performance which gives us the information about the aero mods. TBH: the less power originally, the more dramatic the performance increase ifthe aerodynamics are worth it. Democratic dissent is not disloyalty, it is a positive civic duty.
