I would be interested to know what 'drive in drive out' costs are SC vs Turbo, if anyone could share?

Depends on where you are starting from.
Has your engine been tested? Is it strong? Compression low? Cam in good nick and not huge overlap?
Are you already running an aftermarket ECU? If yes to the above, then turbo is around £3,000 in stalled, plus bigger injectors if needed.

Coco79, that is one amazing garage you have Are you sure you need ANOTHER TVR?

Great figures from this 4ltr after it had gone aftermarket ecu.

I``m assuming its low boost 5psi or so due to no intercooler.

Looks nice n neat as well.

I've been following this thread with interest, my head is telling me 'turbo' given the fact that there are well known specialists to supply and fit.. my concern is whether it would 'mute' the V8 growl. I can't seem to find any details of companies that supply and fit a supercharger..I have to say I quite like the supercharger sound though..

My decatted car used to be 102-105 decibels at track days. Last week at Snetterton it was 95 decibels with the turbo. On a sprint day last month I was accused of driving a hybrid, the car was so quiet compared to Phazed's. So it is not only quite a lot quieter, it is more muted.

Anyone handy with the spanners could fit the s/c kit, it's that straightforward.
It would benefit you if you had aftermarket engine management first but I'm told it will happily run on the existing set up.

Do you have details on who supplies the complete SC kit? Thanks

Secondly, you don't seem to be talking about torque.... You do know what torque is? There's nothing to be ashamed of if you don't... I mean, you do know, that when you floor it from around 2k rpm it's the torque that spins up the rears, punches holes in your kidneys, and causes you to apply varying degrees of opposite lock....???

You have around 370 torques from your fastest ever N/A 5 litre? My titchy wee 4 litre has just got 481

FI is for girls.............. it might make you look good in a straight line, but it won't make you go round corners any quicker

Ah but, dear chap, we're so far ahead we can stop for a picnic while you catch up

Now off to open another bottle OF MERLOT

Thought I'd help out with some little corrections. All the best

Internet speak...... keyboard bravado...... straight line pub talk..... Not seen you on track yet Iain.....

[N7GTX]

Ha ha, and you wont, Chilli. I hate tracks and all that jazz. Last one I did around 4 years ago was in an Atom. Just found it soooo boring

[Engineer1949]

sc power supply all the supercharger needs i am fitting one for a client at the moment watch for the new thread once the gear arrives.

You will have to excuse the wind noise...I'm sure there are some more talented uploaders than me who could get rid of much if it with other software and playing around with frequencies, but I'll have to shield the microphone better in future. Might (or might not) give you a feel for the sound on acceleration so you can decide if its too quiet for you...its only on a standard exhaust at the moment.

I'm going to try and get something better as Chimaera Turbo's are not that well represented on youtube although a couple of guys have posted some good stuff recently.

Also worth noting is mine is modest power and torque compared to some on here.

What do you mean by the 'sound'. You may be confusing the supercharger 'sound' with other forms of SC.
I have no business to promote here

Well, I did manage 610 lb torque from me ickle 450

Tut, is that all :-) You must be gutted.

Very interesting thread.

I've spent the last few years pondering what to install in a '72 Rangie to give it the same overtaking ability as my previous 5.7 Overfinch.

The target is pretty much 330x330.

The costs seem to work out pretty much in the same ball park whether I go for the turbo, the SC Power or a 5L V8D. And they all have their merits.

I've discounted the LS route as I really wanted to keep a RV8 in the collection having always had at least one since I was 21. I just like the little old pushrod lumps.

In addition I have a criteria that is probably notably at odds to TVR requirements, I don't want the extra power below 2k rpm. I want the power for over taking but don't want to be running 10 mpg when just pottering. My Overfinch pottered around at 4.5mpg and while it was fun I see no upside in returning to that.

That ruled out traditional SC solutions and big CC NA. I was left with the turbo option but needing to have bespoke manifolds made. Then I read up about the Rotrex and decided that this would actually give me what I want.

It won't be a wear on the drivetrain in general use and will give a really good boost above 2k to about 5k (the car is an auto!). As such I don't have to worry about beefing up the drivetrain beyond high torque parts that are readily available. I've had a Disco diesel turbo radiator re-cored for better cooling so that gives the intercooler. I've refurbed a 4.0 and it's just in completely standard Rover form. Tuning is going to be via Mark Adams and an Omex piggyback as a cost effective way to get it up and running.

Sounds like a sensible plan if the engine is a fresh rebuild.
Im still 50/50 at the moment.
Just bolt on the s/c kit to a 79k mile engine or rebuild my own engine to 4.6 spec with change for nice heads, aftermarket management, and maybe even a suspension refresh if im careful.
5k is a lot to spend and id rather only do it once.

I can't see how adding forced induction to a 79k mile RV8 engine is going to do anything other than put you on very borrowed time.

When things go bad you're going to be in for a engine rebuild, so that means spending £5 - £6k on the SC-Power kit just to bring you rapidly to the point of spending a similar sum on an engine rebuild, So unless you've got £12k in the kitty I'd be inclined to do the sensible thing and reverse the process, ie start with that nice 300hp V8 Developments 4.6 with decent heads.

Enjoy the 300hp V8D engine or perhaps a little less with a lower compression build designed specifically for your future plans to go forced induction, then when funds permit add some boost. The engine will be built for it and will still be nice and fresh, doing things this way ensures you'll enjoy unbroken service while spreading the costs.

Rather than boosting your way into unplanned spend that may well put you out of the game while you save up for that engine rebuild, you'll be starting the forced induction journey with the engine you'll inevitably need to build anyway.

Planning and common sense aren't as exciting as the prospect of adding forced induction to your well used lump and having a much faster TVR within weeks, but there's not a blower in the world I've ever seen improves engine longevity and when you add one to a higher mileage engine that was never designed for FI, well lets just say "Good Luck".

I think this is by far the most sane route in terms of budget protection.

It's also the route least likely to end up a royal pain in the arse and ruining your relationship with your car. As mentioned earlier, people rarely post about what's gone wrong with their FI route.

Im awaiting a reply from V8D regarding a drive in drive out 4.6 or 5.0 conversion.

[Boosted LS1]

It is sensible to start with a good engine and so long as it's not worn it should be fine. Turbo boost won't cause an increase in mechanical risk unless you over rev. Boost is more about heat management and especially about detonation avoidance. If your engine's a 3.5 or a 3.9 then a switch to a later engine would be a benefit but only because the designs better and the pistons are stronger.

I'd compression test your engine and see if the readings are healthy.

I took a high mileage 4.0 from a late one lady owner Disco. On stripping it there was no carbon, just golden oil as hoped from the incessant servicing through the car's life and we just replaced the obvious bits. The hole for electronic timing was missing so that was drilled out. Being able to control what happens to be enth degree is going to be instrumental in making the engine last in my book. It's a while since it was all planned but I believe I insisted on knock sensors, will need to check that. I wasn't going to run an intercooler as my application really doesn't need it but a conversation with one of the old Land Rover Dakar engineers educated me that a deeper cored Disco diesel rad gives better cooking efficiency over the standard Rangie rad and has an integrated intercooler that saves you from an very ugly and messy integration means that we will now have this.
