Hi folks, does anybody know what sort of power can be put through the s1 chassis and running gear? looking at upwards of 300bhp. Are there any examples of high hp elises around and how do you think it would affect the lotus handling? cheers

plenty of vag 18t conversions running around at well over 300 but its not so much whether the lotus can handle the power more can the driver cope, they can be brutal if not treated with respect

Yes thats what im looking at, im pretty familiar with the 1.8t engine and think that could be an awesome combination, i just wondered what the general opinion was on these and whether the rest of the car could handle those figures. Im used to 'lively' cars and this sounds like it could be a lot of fun!

The popular engine conversions for the S1 are the VAG 1.8 lump, one of the Honda screamers either N/A or Supercharged (I'm sure Scuffers can tell you a bit about them) and also the Ford Duratec unit. Superchargers are also available for the 2zz toyota unit in the 111R/Exige with outputs of up to about 450ish bhp (search for posts by Ronin on Seloc). There's also an S2 somewhere known as Esti that has the VAG unit from the Mk1 RS4.

I have an NA Honda converted exige and personally love it due to the revvy nature of the honda
could it benefit from more power ? well probably but how much is enough

300, 400, 500bhp or more has been done....very sucessfully

some with plenty of race wins and other events like Time Attack that Steve G runs in

the chassis, as in the aluminium tub sure can handle it

however all these cars will have had the suspension,brakes,cooling system, etc changed too....

400+ bhp per ton - presumably a driver upgrade is needed for the vast majority of road drivers (apologies if you're a seasoned serious-car racer)...

I feel the need for speed (well, my Exige S doesn't feel fast enough in a straight line, it's good round the bends) and the question is - what's the maximum power-to-weight for an Elise / Exige on road-legal stickies (888s / A048Rs) that is borderline *sensible* for a *ROAD* car. I am (IMO) competent on track but I haven't stepped up to competitive racing so my driving skills are probably only average for this type of (fking fast) car.

How much do you need to be 'silly fast' without being 'insane fast' and needing to race the thing in your spare time simply to get a handle on its performance?

Certainly some of the trackdays I've done in the Exige have been constrained by corner speed - if there were any ultra-powered Honda beasties there then they weren't a liability (as, for example, a bunch of Radicals would be) because they'd be (perversely) safer by blatting past on the straights but not being orders of magnitude faster in the corners.

Of course, the last trackday I did could have been filled with absolute beginners and this could have severely skewed my perception of whether I can drive or not (couldn't keep up with VTECMatt at any point in the circuit, though...) hehe

(disclosure - I tend to drive at Brands - sharing Snett with Honda'd cars (esp. with Scuffers / Randy driving the things, would somewhat make the point)

So if I want my Exige S to be anywhere near as much of a laugh in a straight line as the Scuffmobile, without the option of engine swaps... it's Ronin, Charlie, a charge cooler and a supply of spare gearboxes, right? wink

400Bhp/Tonne is so last year, you need to be over 500Bhp/tonne to have real fun!yum

seriously though, we have got to the point where as a road car, they are silly fast now, you just have more power than grip on road tyres on the road, and the speeds that can be got to in very short order are just insane...

Mine's around 520 bhp per tonne at the moment and it's still easy to drive on road and track. And although I've done a fair few track days, I'm no expert driver.

I think the chassis can still take a fair bit more power, as has already been shown by a few other people. The thing that makes a huge difference to the overall driveability and one's confidence in the car, is the attention to detail on the suspension setup. i.e, don't skimp!!

(I still can't drive the thing for st in the wet though)

Evening Simon, while you're online are there any other goodies etc available to me yet or am I looking at a built engine now.

Oh and by the way, I found out the other day at Brands that my throttle hasn't even been opening fully. Don't know how long it's been like that for, but feels much better now.

If you can't have fun with 400 bhp/tonne (hey that rhymes - I'm sure someone could start a poem / rap with that line... silly ) then I suggest your adrenal glands are somewhat jaded. A bit like the guys who can't get high off heroin anymore and need to IV fentanyl. Let's hope motorsport isn't banned under some spurious environmental argument, you're going to have one hell of a cold turkey going back to 1 litre Micras, etc. hehe

Do you (or have you) race bikes, Simon? Or just play with litre bikes on the road? I'd guess that your Lotus is pretty much the same sort of accelerative rush as a big bike...

at the end of the day, it's all relative...

fast as you think a 500Bhp/tonne Elise must be, jump into a group C or an F5000 car sort of put's it in perspective...

Yes, I agree, my own senses have become somewhat distorted, I have a bog std S1 in the shed at the moment, driving it and trying to come to terms with how I felt about one 12 years ago when I first had the same car is unreconcileable, it feels truly pedestrian and gutless.

Oh, and BTW, yes, I used to be into bikes, but ~10 years ago I sold my last one, it was starting to hurt (if you get what I mean), all that said, I was never that brave on 2 wheels (compared to some I know!)
