That's excellent for that spec car. I have same but turbocharged, I reckon mine is a lot more than 554kgs! 1 Quote Link to comment Share on other sites More sharing options...

Flying Carrot Steve Posted August 19 Share Posted August 19 So a 420R actually has a power to weight of about 363bhp/tonne. No wonder they are slow 😂 (kidding) We all know Caterham have 'allowed' people to think the car's name/designation ie 420 is the power to weight. Nice sales ploy I'll give them that. I'm hoping to get mine down to around the same figure as yours @Ian Kinder (Bagpuss) - Joint Peak District AO 1 Quote Link to comment Share on other sites More sharing options...

They cheat slightly and use the dry weight (no fluids!), which isn't too realistic! You're welcome to correct any mislabled Caterham products with a sticker should you see any.

Found this in an old Westfield World We have our annual weigh-in at our next Essex meet (8th Sept), so be interesting to see what ours weigh this time around, some including mine have changed quite a bit. 2 Quote Link to comment Share on other sites More sharing options...

You're welcome to correct any mislabled Caterham products with a sticker should you see any. Public service etc. What's the plan? Lightweight Jack Webb Motorsport LiFePo4 battery about to go in, then after that either grp or carbon seats to replace the sport turbo ones I currently have. I reckon that's going to save me at least 20kgs? Possibly a bit more. After that I need to get it properly weighed as I'm not entirely sure what it currently is. I had it on the local council weighbridge which only did one axle at a time. With a full tank of fuel it said it was 670kgs. I assumed it was correct but now am not so sure. I weighed the car myself using a 200kgs scale and equal thickness blocks of wood, one corner at a time. It came in at 644.7kgs. I suspect it may be somewhere between the two so need to get it on some proper scales. Also it would tell me how well I did with my in-garage bathroom scales weighing attempt. That way I'll know if it's worth doing in future with any mates cars. After the seats and battery I'm not sure how much further I will go. My front wings need replacing at some point so no doubt will go carbon but after that I doubt I'll do any more lightening. I'd rather spend money on driver training tbh as the car has more ability than I can handle atm. Some track day driving lessons would be of more benefit than more carbon for me I think. 2 Quote Link to comment Share on other sites More sharing options...

Oh yeah, I've also replaced the large and heavy fire extinguisher with a Fire Safety Stick, that's saved me 3.4kgs. It's all adding up @Ian Kinder (Bagpuss) - Joint Peak District AO 2 Quote Link to comment Share on other sites More sharing options...
GaryH Posted August 19 Share Posted August 19 My factory 2005 Sigma engined car comes in at 549.5kg, within a kg it's corner weighted across the axles with 49:51% front:rear weight distribution. That's with 1/4 tank of fuel (gauge indicated, so most likely a random volume), factory wheels, sport seats and carpet. Gary 2 Quote Link to comment Share on other sites More sharing options...

Gary The sigma engine is a good 20kg lighter than a zetec, so it’s a great choice for weight saving 👍 1 Quote Link to comment Share on other sites More sharing options...
