Makes you think doesn't it, buy a cheap N/a and supercharge it

You might find that the list quickly grows to include uprated clutch, lightened flywheel, 16/17" wheels, Toyo or Yoko tyres, uprated suspension and brakes ...

PS And if you want to go over 250 bhp there'll be engine internals, possibly a new manifold and exhaust ....

Now you've went and spoiled it by being sensible



5k doesnt seem that bad when compared the 10k for Honda'd Elise options

That was my point

That's insane! How much have you spent on the N/A so far? Surely it would have been cheaper to get that kind of performance from a VXT? (Sorry relatively new to all this so still learning, slowly )

Er yes still learning slowly.

Yes the NA owners usually get slated because they bought a cheaper car or because the turbo is more tuneable...(yawn )

Perfect example (that cost doesnt come into the equation) of what can be achieved and I bet it goes like s**t on a preverbail shovel.
I'm still undecided on which route to go although those are mighty impressive graphs and have given me a more informed choice.

Of course there are those of us that dislike the turbo delivery.

Ok I admit it I'm poor!!

(Watch out when mine is finished though!!)

mmm...I have been passed more than 1 VXT on track on more than one occasion; they may have been just standard ones though. Sorry I keep referring to the track, as my car is not road legal. Although, it could be back on the road for about £700. My car, I consider to be a very standard car, it may look more radical, but it’s really no different to all the other NA SC conversions. For the money it’s a steal & I prefer driving around the twisty stuff and not around the M25. Yes, everyone on this site has a great passion for their own cars. The turbo guys greatly outnumber us Supercharged guys. But I wonder why Lotus decided to Supercharge their cars? ...mmm

It would be interesting to get a sorted Turbo on track together with a SC car, each with in car video cameras. On YouTube or similar you could then open two windows up one with the turbo car & one with the SC car, load them into memory by pausing them at a similar point on the track and then play them simultaneously in sync. I have done this several times against Elise’s, Exige's and other cars. It makes for interesting comparisons.

Looking at the gradient of that powercurve the torque going to be flat as a pancake.

It'll be interesting to see what the 4-2-1 will do as the SCVX with a wepon R didn't really produce much more, but that was still using the Miltek u bend and box.

Jim's comments on the Weapon R manifold was that it looked really nice, but for forced induction applications a 4-2-1 is the only way to go, he's proved this on SC Elises & Exige systems.

MAXR

The Weapon R is 4-2-1

Jim's manifold for the Exige S is 4-1

[DundeeVX220]

Actually I wasn't slating the N/A at all I was just thinking on a cost effective basis, i.e. price of the car + price of mods to total performance. I would assume it would cost more to get the N/A up that kind of performance than the T but then you have to take into consideration the relative costs of buying the car? Again, I wasn't having a go at NA owners I was just curious as to which method gave the most bang for you buck so to speak. Either way with those figures that thing must be a beast

I've just made a man-mess!

How much, if you don't mind me asking? (need to know how much it'll cost me to get that sweet curve!!)

About 5k(ish)

Was that from a completely standard NA? or did you already had other mods?

I must have misunderstood Jim, sorry I'm not technically minded when it comes to cars (I admit that openly) But Jim is adamant that his 4-2-1 manifold is better suited than the Weapon R for the SC. When I get hold of him I will clarify the situation and let you know his comments.

now you might laugh but my missus has just bought an slk merc 2.0 s/charged its only 160 bhp and it weighs quite a bit compared to a VX (1350kg) but its s o quick for what it is and the power delivery is fantastic so linear!! this is the 1st supercharged car i have ever been in so i can only imagine in a VX it must be absolutely awesome!!

Sounds very interesting idea, I've owned an Exige S1 and recently driven a Honda'd Exige S1 S/C and an Exige S2 S/C, I can quite imagine how well a VX220 S/C must go.

Now for the VXT's defense, standard VXT's are in my opinon are a really under developed car in standard trim. Don't get me wrong its a nice car for certain conditions, but if were talking track work oh dear.

A modified VXT with upgraded suspension, brakes and reworked engine/turbo say stage 3 will be very close in power and weight to the VX220 S/C so it should be very close.

The track selection will play a part, tight circuit with lots of chicanes and hairpins, the VX220 S/C would have the advantage, bigger circuit longer straights that would favour the VXT.

Or we could just play GT4 Opel Speedster challenge races instead.

2 ways to make a car quicker.

the normal way is to add power but the clever way is to "add lightness".

an na is 100kgs lighter than a turbo, and even when you add on the supercharger gubbins id be amazed if it was anything less than 50kgs lighter. especially when u consider stage 3 turbos need a charge cooler.

so you get a different power curve and a lighter better handling car. excellent!

my car (a lowly tuned na) is fully paid off and I could change it for a turbot tomorrow (or exige s for that matter) but there simply isn't any point imho.

more to life than straightline performance - if there wasn't we'd all be in modded jap boxes.

........in saying all that im still toying with the supercharger conversion but might just get my cbt and buy a crotch rocket instead

Stage 2 (and, when released, Stage 3) SC's also have charge coolers.

Jim links his 4-2-1 manifolds differently to the weapon r, which is better for SC cars.

Some info from Courtenays on pg 2 of this thread clicky

[MAXR]

Just out of curiosity, do any of you know what your cars weigh? A standard NA is 850kg (ish) I think. Mine is 848kg (ish) with 2/3 tank of fuel after the SC conversion inc Charge cooler etc. I would be interested to know what the modified turbos come in at. MAXR

I've owned a few turbo cars over the years, including a VXT and VXR. My Exige is the first supercharged car I've owned and I have to say there's absolutely no way I'd ever go back to a turbo engined car.

I'd forgotten this earlier thread. Great vid with glowing manifold here:

[danger7]

For the VXT modified well there's a big variance in weight depending how big someones cheque book is, but there a few highly modified VXT's weighing 830-850 kgs in road going trim, so track orientated VXT's are running 820 kgs all with around 300-350 bhp. I know Colin Blowers VXT is weight restricted to 820 kg & 300 bhp to comply with FIA GT regs. Mines a portly 900 kgs with all fluids and 3/5 fuel load its achieved without stripping the interior or cutting big holes in the bodywork and not a hint of carbon fibre anywhere. 30 kgs has been shed by changing the alloys, lightened flywheel, big brake kit, ferris wheel for the alternator removed and replaced by an alloy diecast tensioner, precat downpipe changed, installed a lighter drivers seat err that's it. Loads of stuff you can do further and worth probably 65 kgs in total. Cheers Ian
