Interesting. Anyone got any background on this? (OK, I should email the seller, but I'm not about to buy it so don't want to bother him).

Hi Pete,
TBH I thought of keeping it for use either on a properly engineered speed 6 or my old Cosworth 24V which had twin turbos. If I was to run a supercharger next year I'll be competing with LS powered GTFs but with less torque, a lot more weight and smaller rubber. The T350 is more suited to an assault on class B where I'll only need 400ish bhp which we can do normally aspirated and I have a new engine deal based on that. The supercharger would also make the car ineligible for the ProMIL GT Cup which I also want to compete in.
A build like the T350R isn't cheap and I can't afford to hang onto kit I won't be using so the procharger, TKO box, the Cossie engine and quite a few other bits and pieces have to go. If I could find a cash sponsor the situation would be different, sadly it's not.

So did the Supercharger/engine combo work OK? Or did the engine only last 6 hours (thought I'd get a Speed Six joke in before others).
A 100hp poke in the power front would suit my car nicely
I'm hoping TVR Power to a charger upgrade for the Speed Six one day
After busy homework for a year on many options before settling on an n/a upgrade (running well but not yet dyno'd) .... the main issue is that to take the extra torque and heat reliably you need to significantly upgrade all the S6 internals and the transmission, and rather more expensively than the Rover V8.A 100hp poke in the power front would suit my car nicely

That work on it's own can give you rather more torque and power, and depending on spec taking you to the limit of road tyres.
So, though personally I like the U.S. approach of too much is just right, it's a matter of how much extra wheelspin you REALLY want!

Hi Paul, glad your motor is up and running, the dyno figures should be very interesting, particularly torque.
ceejay
Hi Cliff, yes all good in theory, the dyno and more importantly in-gear times will prove it all right or wrong (or even, maybe someone's organising a TVR 1/4 mile next year?) ceejay
Good luck with your own developments anyway; went well with just standard engine so surely has great potential, & driver didn't seem too bad either.
When we were running on the dyno with the procharger we also did some runs with the procharger pipework disconnected (the engine was effectively n/a) but the supercharger belt was still connected up. We saw 380bhp at 5.5k revs when we were still playing with injectors. If you take account of the losses driving the supercharger and getting the fuelling bang on to 7K I reckon 410 - 420bhp was very realistic. To get that I would think a nicely ported head, bespoke map (we were using the Emerald which always seems to work well) and a free flowing exhaust would do the trick.

This raises a question I've been meaning to ask for some while, being has anyone benefitted from changing the injectors on a SP6 to bigger ones. This seemed a fairly standard upgrade route for the RV8, but I can't recall reading anything similar in respect of the SP6 ?.ceejay

I spoke with an engine builder I have the greatest respect for. (He's currently building my 3.0 V6 Essex engine). ceejay
He has a 3,6 engine in his shop at the moment and is rebuilding it to a good spec (steel crank, rods and forged pistons) some porting, cams, balance and a remap etc. He belives 420bhp with good torque is achievable - his reputation dictates that if he says it will deliver that, then it will be there or there abouts.

But as you say he is a practicing preacher.
And naturally aspirated.

That 3.6 ltr speed six you refer to John will be a 4ltr when finished and the projected figure Mr Beardy is aiming for is 430/440bhp with 350lb/ft torque on a nice flat curve. Well that's what I have heard through the vine, how true that is we shall wait and see.
Must be the same one as I think he only has the one S6 at the momentYI8TVR said:

He could do with being supercharged from time to time, but hes a bit old for that sort of thing

P.S. I have a TKO600 CR gearbox, modified SP6 bellhousing, superclutch and propshaft for sale too........... changing to a T5 dogbox or sequential next year.
Fancy a 6-speed Quaife sequential Cliff? Do you know what ratios are in the TKO600 you have?2.87
1.89
1.28
1.00
0.82
Is the quaife any good? Any idea of the torque rating?
