That would be really interesting to see what figures come out of the sim..
Are you able to send a PM, then when I reply to the email, reply with the latest dyno graph? (I have a Dyno Dynamics one from the engine in 2014!)

Also, do you know the model of the gearbox?

That would be interesting for me as well. Real better though

465bhp, 1160kg, T56 magnum gearbox, standard T350C diff.
No problem, will add yours into the mix. Do you know which Magnum variant you have? (0.63 or 0.50 6th gear ratio)

Anny updates of owners with that lovely Sportmotive Evolution chassis?

how is the difference, can you feel it? does the car feels more planted like the more modern TVR's?





That's my chassis, ...........it's hard to give an accurate comparison of the standard chassis to the Evolution chassis.
I think you would have to drive both chassis on the same day, same road, etc. which of course was not possible,
The car does drive really well, it's very positive at low speeds (although I think I will soften the front a couple of clicks) and is very stable at high speeds and handles bumps well.
The turn-in is pin sharp and so far I have not detected much if any understeer, it accelerates in a straight line and it's not tail happy,
but then I don't provoke that, the more time you spend sideways the less you go forward and with an LS3 under the bonnet sideways is not difficult.

:-) good to hear, a lovely chassis and pictures, makes me want one :-) thanks for trying to explain the differences, good to read.

I see you have that under a Griffith carros, cool, I owned a Griffith 4.3 BV long long time ago, and indeed, they could be a handful especially the first day you drive it haha, the powerband was like a on of switch like, a tip of the toe and of you went, but not that long, say 1.500rpm or so massive and then a bit less, not as smooth liniair? like say a BMW V8 over the rpm range.

and ow, that first day, I attack'd the road to the highway, like I used to with my BMW M cars, shifted back before the corner (still straight line) and ow, rear wheel blocks for a short moment because of the lighter car and the torgue haha, the first and only time, after that I adjusted my driving style to the TVR :-)

What I was thinking about such lovely chassis/engine/etc combo, the wheelbase is the same as some classic pre '80 TVR's like Vixen etc, so I asked Sportmotive a few months ago, is it possible (because I like the say Vixen models) to put that under a Vixen carros?

They answered, yes, they could make that possible, would not be to difficult they think.
So...Vixen looks, supercar power and handling, with say a LS3/484/525 hahah

Best is then to find a Vixen with a rotten chassis and bad motor and interior etc, for not to much and then make it 'your' car, still classic looks, but wit more modern underpin or how you name such, and a lovely interior etc.

GTRENE it may be cheaper to do that to a S series car as they have the 'looks' and I think the same wheelbase. I have previously changed the old v6 for a cos worth version and now in the process of fitting a Jaguar S type v6 using a refreshed original chassis.

Its about the 2286 mm wheelbase (which it shares with the Griffith/Chimaera), see in this overview how many TVR's use that wheelbase :-)

a lot of pre 80 classics to choose from.

indeed, don't wake up those people, it seems to be a great/better chassis, so who would complain,
if I was in the market I would order a complete version, so chassis/engine LS (minimum 480hp) etc and new interior, maybe a bit like this for example.



great wheels and brake set etc, then you have a as new TVR but then 'better'
What a great idea that would be whistle

Yep

you will probably find the S is the cheapest and has oldish looks

true, then the S finally gets another better chassis/suspension set up :-)
I didn't thought about the S version, because of the different chassis/suspension set-up and in my case also because of 'cabrio' and they are not pre 87 just in case of a very low road tax (but then no driving in december-januari-februari) even better when they are 40 years old, means no road tax in NL and you can drive (if you want) also the whole year.

I am sure this is a great car and the upgrades would have been costly. Also it is a rare and unique car but isn't 48k an awful lot of money?

What else can you get with that performance for the money?

I agree it will be pretty rapid and in the grand scheme of things is not a ton of money compared to what you can spend. However there are options. Around £50k buys a massive amount of 2nd hand car these days.

I recently bought a 2010 Jaguar XJL SuperSport for less than £17k. Granted not quite a lithe small 2 seater sports convertible but fast and comfortable. It drives very well and with 510bhp is no slouch. Handles pretty well for a big limo!

What kind of 0-60 and bhp would something like this be?

Given the amount of 4WD twin clutch or auto box mass produced cars with 7 or 8 gear ratios a TVR isn't going to out 0-60 such a car unless you have everything spot on and go to a drag strip!

Not trying to disrespect the Jag, but it is still only about 300bhp/ton(?), with the Evo Chim being 530bhp/ton, a figure higher than say a used 570s which is quite a bit more expensive....

I've still got to post the (simulated, but based on lots of collected data over years) acceleration stats, but here is one for now.

60-100mph in 3rd - less than 3 seconds.

Thanks....very interesting. Of course the Jag doesn't come close and not remotely similar. Just really a highlight as to what you can get for about a 1/3 of the price. I agree the raft of £50k or less sports cars are not quite the same as this Evo Chim

I'm toying with the idea of moving out of my current Chimaera into a later T Car or something a bit more interesting that a stock 400. There were a couple I came across:

https://www.ebay.co.uk/itm/TVR-Chimaera-450-Turbo-...

https://www.autotrader.co.uk/classified/advert/201...

Or something a bit off the wall:
https://www.autotrader.co.uk/classified/advert/201...

My plenty nice enough Chim 400 owes me £12k so was thinking of something upto £25k with the Chim 400 going the other way. Thought of Tuscan's and Tamora's and there seems to be plenty of options. Or I could spend some cash on my, maybe Turbo charge it or do some mods.

Is the Evo Chim your car?

Not my car, I jumped in as I've done a lot of calculations for a few TVR PH'ers in the past, noticeably a couple of guys who have done less than 11 secs for a 1/4 mile (at more than 130mph too), with one of them doing 202mph on a runway.

Agree on how there are lots of options out there. Personally I'd not be comfy with regards to complex old cars but that's just me.

You describe plenty options and imho what is correct is what you fancy, whilst being suitably pragmatic doing so. Some people like regular variety in their cars, others like gradual improvement over the years for a single vehicle smile.

Thanks for confirming. Looks a cracking car and a great job by Ian. I bought my current Chim 400 from Ian and he is a top man and am content with what I have for sure. Always that dangerous longing for improvement though! To turn content into happy or even more!!

After a bit of digging around on this car a bit more info is easily found. It seems the original build completed by Ian @ Sportmotive was for a PH member on here. Obviously he spent a stack of cash on the build and like all these things it often doesn't make total financial sense.

It was up for sale just over 3 years ago for £40k:
http://bay2car.com/TVR-Chimaera-6-2-V8-LSA-Superch...

Maybe the current price is pushing the boundaries a little. At £40k or mid to late £30's it might make sense for more. I just don't see too much value at £48k personally. We are all different of course.

Looks like it has only done less than 1k miles since it was sold circa 3 years ago which seems a crime. Not bad if you can buy a car for £40k or less and not use much then sell for £48k 3 years later though wink I could do with a few of those cars smile

the engine alone costs as much as some Chimaeras (more even)

I've seen the car.. Absolute Bargain compared to doing the project yourself.
