I've seen the car.. Absolute Bargain compared to doing the project yourself.
Thanks. Wow....nice engines. So the SC unit in that Chim would be the £16995 one? I guess that is 2/5 of the 48k.

The LS 376 will give a reliable 525 brake and bundles of torque for just under £7k inc. VAT

+VAT!!

so 20,000 engine.. assuming all the ancillaries, run kits, etc are a similar amount between my build (not at Sportmotive) and this.. there is a 14k difference just on the engine.

Correct all LS crate engines come with only exhaust primaries and a flex plate, so you need to add

Flywheel £307

Clutch £320

Starter motor £265

Alternator £400

Run kit = ECU, FBW pedal, engine loom, MAF and O2 sensors £1300

So about £2600 + engine £7000 = £9600 inc. VAT still under top spec RV8 engines with fully mapped fuel and ignition,

There's a bit more to factor in depending on your chassis like exhaust primary and secondaries, engine/gearbox mounts, gearbox change/upgrade and maybe prop shaft

In the past there were a few (builds with a LS engine) like Tamora-Griffith-Chimaera-T350c- with a LS engine, some with new ,some second hand engine, non had the Sportmotive chassis, but most were under 30, from those, most around 25k and even 1, a tamora LS2 for just 15k, that one was in 2015.

so 48k is ofcourse a big step up, also that car is, but I can understand why some think, thats a bit steep, even when it costed perhaps way more to get it that way.

I see that car also for around 35k =ok
but...if you have lots of spare cash to play with and do not want to wait for a newly build, I guess it can sell for that money, it got great specs for sure.

No this car has an LSA: http://www.partsworldperformance.com/lsa-superchar...

Still a mega motor though! The LS9 you were looking at costs a lot more as it has a lot of fancy titanium parts in it though doesn't actually make much more power. That's the one in Paul Black's mental Sag

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?
There is always the option of buying mine. It’s advertised on Facebook and will be on PH before the weekend. I need to book my crossing for Spa next month and it will a simpler decision which car to take if the Chim is sold....

One reason the LSA in the Chim gives more power than the GM rating is the exhausts on the Sportmotive install are less restrictive than the GM "block hugger" ones.

There must be a ton of variance in these type of builds as many say. One build could be with a used engine with not the detail of changes of others. A 'similar' build could easily be half the cost of a FULL detailed build. As always, the devil is in the detail. The spec of the builds can be very very different.

I think the issue for me on the £48k one as there is no doubting it will be a great car but the increased cost over the last couple of years. It was up originally for £40k:
http://bay2car.com/TVR-Chimaera-6-2-V8-LSA-Superch...

Of course, that doesn't mean it was sold for that possibly less though unlikely more. However, if we assume £40k I don't feel this car is warranted to be increasing by 20% in this short period. Unless of course more money has been spent or further improvements/mods as this is unknown. All I know is that £48k is pushing into some real big boy territory.

I'm sure that everybody knows that you don't need to to put a GM motor into an Evolution chassis you could run an RV8.
Or the other way round, I had my LS3 in a standard chassis, (still got most of the modified bits) and then upgraded to an Evolution chassis.
Either way round I think it's a question of power, and ride and handling, and how you balance the two against cost and outcome.

It would be really good to do a back-to-back test of an evolution chassised car against a well sorted standard chassis car, like mine of course!

I think this could really only be done using a track as the sort of speeds that you might notice a difference at, (going round bends of course) would not be able to be obtained on the road!

As much as I would love 600 hp in my car, if I had my sensible head on I would say that is too much for a lightweight road car with such a short wheelbase. Much better suited to a cerb. imo but absolutely wonderful for pub talk!

I agree,.... mine is making about 440 brake with similar torque and that can be a handful without all the electronic aides that modern cars employ

my LS3 is 'only' the 430 bhp version..

yet when installed and on 99 ron, makes 465 bhp.(with a bit more to find, running a bit lean)

Mine is a 430 as well, it also made over 460 brake on a rolling road tuning session but I'm not sure how accurate that is.
I believe that its making more than the advertised power but it seems strange that GM would under rate it by so much.

fuel? 91 -93 ron typically available in USA.. and as they make so many, say on the little conservative side, less they get sued by the off one being down?

my 465 bhp was on 99 ron VPower (Shell) and it was running a bit lean, might get it up to 480 bhp

It certainly feels like it!

If you ever intend to sell let me know (or maybe even trade ;-) )

Good points.......what size throttle and inlet manifold have you got? A102mm throttle and FAST manifold would certainly make a difference.
I've been mulling those over, and a GM hot cam and remap probably good for another 50 - 60 bhp for around £2k in parts.

Not looking to part with it it's way too much fun!
