Has anyone had this done?

What is the performance like? I assume a much smoother delivery, but what are the 0-60 times, and mid range overtaking power?

I am currently in "negotiations" with the other half about the possibility of fitting a Supercharger..... Well, putting it a different way, I want one, she doesn't.....So is it worth the aggravation?

Wouldn't have though 0-60 times would be affected much. 0-100 however smile A super charger on a 5 would be madder than jack McMad's mad aunt smokin

Hence the reason my better half and I have currently entered into negotiations...biggrin I've thought about it a few times when I had the 4, but got the 5 instead........... But now......

E1, how do you find it? Smooth power delivery? Have you tested the 0-60? I thought I read somewhere (could have dreamt it though - that a 4.0 with a Supercharger was about as fast as a 5.0?)... Is it about 5k?

Am I going to be looking at Ferrari 360 performance?

I only picked my car up on Saturday. The weather hasn't been too dry since then, and i have a niggle with the power steering which has kept me sensible... but the result of the supercharger is awesome yikes

The aditional power, and there is buckets full of it (allegedly 80 to 100 bhp, but i'll hopefully be getting this checked out soon), is delivered in a sublime, smooth manner, hitting its peak between 4000 and 5500 rpm. It is like a different car, and will definately take some taming.

Do it... you know it makes sense biggrin

nono

Chart here:

http://www.sc-power.co.uk/SC%20Power%20Supercharge...

4L is about 50 bhp (at the flywheel) more powerful than a standard 5L (310 v 260 bhp). Per Paul at Austec the charged 4L is about the same as a very highly moded (not Supercharged) Griff 5L.

That figure is based on only a 15% drive train loss which is VERY conservative. If you based it on (say) 18% losses then the flywheel figure for the SC400 is 322 bhp which is 62 bhp more than a standard 5L.

So, if you've currently got a 5L imagine another 50 to 62 bhp being added to it and you'll get the idea of a blown 4L. As has been said the increase in felt most keenly in the mid-range where it just seems to keep on pulling forever.

Of course the 5L SC will be even more of a monster.

I'd certainly be interested in hearing of any performance increases - i.e. 0-62 especially - the 5.0 on the mid range to overtake is already superb. I'd also be interested in how much harder or even easier it is to drive. I imagine with a smoother power delivery it will feel steadier on the roads when accelerating.

My better half is a bit concerned that it will be too fast for her to drive at all.. She's not too keen on the 5.0 as it stands...

I have a big blower on the 5.2 in the purple wedge... clocked 50-100 at Lydden in 2.74s on Saturday. Not mad but a lot of fun. 525 bhp though. However... the more power the more the costs of getting it reliable go up as everything has to be upgraded. I've broken two gearboxes so far before getting the cts quaife t5 box. I also need a 750lb/ft competition clutch.

As I said a few months ago. It all depends on how much power you want and how reliable you need it.

"340 ish - go with the SC power kit. Alternatively get a John Eales special N/A engine that will provide the perfect base to build on. Not cheap initially but saves thousands as the power is upped.

350-400ish - start to find limits with standard ecu, injectors fuel pumps, induction, crank and engine bottom end etc. The engine is on a knife edge and get any thing wrong and it will shrapnel. Special pistons, internal engine upgrades start to become essential. You can risk it but how lucky do you feel? Biggest issue is leaning out which is why it is so important to upgrade and address these areas. Gearbox should be treated as a consumable or upgraded. Cheapest way as it reuses the bellhousing prop shaft etc is the CTS/Quaife upgrade but budget £1500 to 2k for it. Clutches also become consumables unless you go multiplate which usually means a new flywheel. Again budget around £1000 as the different flywheel often requires a geared starter motor. Alternatively declare the clutch a consumable. I did get through 3 uprated standard size ones in a year before switching to a triple plate sintered AP clutch.

450ish - Throw everything away and start from scratch. Hence the starting with a JE special initially. At these levels the engine needs to be built as strong as an OX. The rest of the system needs to be engineered correctly with no compromise otherwise the engine will shrapnel at the least excuse. Be prepared to strengthen everything on the transmission including the propshaft/driveshafts. Cooling, air charge temperature and the whole environment must be kept under control and that requires a lot of work and money. Again if this isn't done, the risk of shrapnelling the engine is increased.

500+ - requires real engineering and resources to get this reliable. Currently my setup has been running for 20 months. Delivering around 470 bhp at the wheel.

Alright I compete in my car so the power gets used and then some but I can't see the point of having 350/400/450 or whatever bhp if everytime the throttle is pushed there is a fear of what will break next? "

I don't want huge amounts of power, but more than she has, and a bit more all through the range. An SC kit I suspect will be more than suitable for my needs as quite frankly I am simply being greedy in wanting that little bit more - the car is really fast enough, certainly in mid range to overtake, shovels and s**t spring to mind..... But I read about the SC kit, and the little bells went off.

So I'd like to find someone who has it on their car, and the real world performance figures that they achieve....

I'm not sure why you would imagine that. With more power on tap there's more chance of breaking traction and things will tend to get frantic a lot quicker.

Jasandjules, if you want "smoother power delivery" then perhaps you should be looking at (custom) mapped ECUs. Emerald is one that springs to mind, but I have zero experience of swapping out ECUs.

I thought that's what I read in the article, a smoother power delivery made for a safer drive?

Biggiles, it's certainly an option - I am also interested in how dramatically, if at all, the fuel "economy" will be....

Unplug ECU box, unscrew 4 screws, open box, pull out ECU carefully, insert new ECU, screw back up, plug box back in.

Oh and ground yourself to be sure.

Takes about 2 minutes.

Yes, and it's a sensible investment and will probably improve fuel economy. hehe

Just thought I would pop in with a few facts about the SC500

8000 hard miles now completed in the car.
Currently running 400bhp and nothing broken.
Enough performance to breeze past a GT3RS round Spa.
Over 30mpg on a run, a bit less on track hehe
A very impressed TVR Le Mans driver saying that the power delivery is so smooth its safe.

I'm more than happy to meet up with people interested in the systems, give them a ride and answer any questions. smile

There is no way on this planet if you put to equally skilled drivers in a Supercharged TVR and a GT3RS - the GT3RS would never lose.

It wouldn't happen, it's too good. I've driven an SC TVR on Spa and done hundreds of miles in the GT3RS is about the best track package you could ever buy, bar none.

SC500 - do you have 0-60 and 0-100 times? (things like 400bhp make no real difference to me, I'm a bit more simplistic).

I assume you have an SC System on a 5.0 (is that the Griff?) - do you find the power smooth enough to control?

30mpg on a run is a bit better than I get out of her now !!

Can I assume it would also be necessary to improve the brakes rather a lot?

Oh, and how much noise does the SC make? I don't want to lose that V8 rumble at all.

Dave, who did you find to insure it ??? And how much did it go up by??? I understand Allianz won't insure a supercharged TVR , so Mannings (and I assume Herrarty) won't quote.
