I wasn't questioning the desire for supercharging a speed six. Or that a genuine 480bhp wasn't a great achievement in itself. It must be utterly ballistic with that and the chassis will have its work cut out for sure.

I was only wondering if 600bhp is a step too far?

Don't get me wrong, I've long been one of the 'too much power is just enough' brigade. I have a 200bhp motorcycle and a 250 bhp Caterham 7. But I also know you can ruin a car by overdoing the power. The bike is really there as my own personal roller coaster. The Seven is completely over the top for road use now but relative to its size and weight it has very big, very sticky tyres at the back. If I put the equivalent of my tuscan's tyres on the back of the seven it would be quite a handful.
Unfortunatley the best person probably to answer that question is Speed Eight but I believe he no longer frequents PH due to the attitude of some PH'ers to his Chevy V8 conversion frown

The last time I went on a group hoon with Speed Eight his Mk1 Tuscan was running a 650bhp Chevy engine & he felt that amount of power was close to the maximum the chassis could handle. His conversion worked out 2% weight differance between the front & back of the car so was fairly neutral when cornering.

I've no problem with 600bhp in itself. I'm only interested to know what other mods pascal and RG have suggested/done to get that power down on the road. The traction in my tuscan is pretty good at coping with around 380bhp (at the wheels) because the suspension allows a bit of dive and squat. The Sagaris offers less of both and under hard braking it's more stable on the track but ultimately has not quite as good traction off the line. (I used to own a Sagaris in case anyone's wondering). But the Saggy's wider track helps make the car overall more planted and as a result always felt like it could use more power.

I wouldn't say no to a genuine 400bhp, maybe 420bhp in my Tuscan but anything more than that I'd be looking at suspension, brake, diff upgrades, wider wheels and wider, stickier rubber. Anything near 600bhp and equally enormous torque and surely gearbox and driveshaft need looking at too.

Otherwise that Pirelli ad with Carl Lewis wearing stilettos comes to mind.

600 is not a problem with regards traction but you need to be carefull in first and second especially (i am talking about a Sag of course here).

A brake up grade is sensible, the diff needs changing - I am running a 3.08 and could do with a 2. something. The prop shaft needs some work to make sure it can handle it and the drive shafts need to be changed especially if you are going to run sticky rubber.

I ran the car with the standard suspension for a while and then had Nitrons put on and the car needed them though it may just be that the car needed setting up right.

Engine mods: a whole shopping list basically.

In terms of suspension: better shocks, new suspension triangles, AP brakes (as per Red Rose spec) still at the front for now ( thinking of upgrading these later on if these don't cope with the power, but for now they seem to work fine).

Diff has been upgraded to a Quaife differential, clutch is a triple plate clutch now.

Stickier rubber will be a part of the next "upgrade", for now it's running on Michelin Pilot Sport at the back, and they seem to cope with things pretty good too.

Gearbox: brand new one, if it isn't able to deal with the extra power, I'll put in one of those high torque gearboxes.

Not that much, there's a lot of grass that keeps the sand in place. Personally one of my preferred tracks, after the Ring, Spa...

I took from you doing the conversion you had already done your gearbox but of course it is the same engine- I can not see how your old one is going to handle it.

It all looks good to me.

I agree Dom that the M3 has a more tuneful note to it whereas pascal has just gone for nothing but noise, but shouldn't you be posting vids of one of your S6's? I guess you're allowed to like other people's engines. But one of the things I like about my Tuscan (Spitfire) is that it's not an M3 (M for Messerschmit) so maybe I was hoping that TVR Power was run by a blinkered xenophobe like me!

I still think M3s are a bit limp wristed compared to a TVR (that supercharged one excepted).

On the subject of noise I'd love to get rid of the tuscan 'rattle' (or metallic rasp) sound. You know the one.

What do you advise?

My Saggy didn't make it and it masks that lovely V12-like gurgle that you get in a Tamora or T350.

Just as a remark: the "silencers" on the car right now, are the ones delivered with the custom exhaust system, and are nothing but straight through pipes.

The actual ones should be arriving today, and from what I've heard so far, they'll be a lot nicer to listen to. It's indeed a lot of "noise" now, and for me personally there is too much metallic sounds in it, due to the high pitch. I always liked the low bark of the engine before, which I hope to get back with the custom made silencers smile

I'll post up videos as soon as they're under the car smile

I will post a video on my forum within the week, im not into silly loud exhausts, street sleepers are the best

If you mean the "sewing machine" noise from the finger followers then you'd need Racing Green's "Finger Follower Free" head. The difference is remarkable.

No, not the sound from the head. It's the rasp from the exhausts rattling at a certain frequency.

Not at all interested in getting rid of my finger followers but thanks anyway. I was amazed how ordinary the S6 sounds without them.

I'm firmly batting for team TVR Power.
