Rebuilt engine, 1000 miles ago

[nobody important]

I'm picking up my dream Tuscan next Saturday. One thousand miles ago it had a rebuild by Straight-Six. Will the engine need further running in, or can I drive it how a Tuscan is ment to be?

[icraigmy]

If you want another early rebuild then yes, but my advice is to take it easy for the next 3000 miles. I did this and am now coming up to my first 12,000 mile service since my rebuild. I started opening my Tamora up after it's 6,000 mile service and after about 8000 miles have cained it on occasions. Treat your rebuild well and it will reward you with many years of motoring.

I just can not believe that you should drive 4000 miles easy after a rebuild. Normally 1000 miles should be enough for running in and then the next 500 miles gradually increasing the revs and load on the engine. But don't take me for the word I have hardly and experience with SP6 - ( the only one is my SP6 at Str8-Six for the rebuild that should be finished next week- but I didn't do the running in on that one )

But I did the above mentioned running in on my Italian sports motorbike and I never had any trouble with it, although they have a reputation among bikes like TVR among sports cars.

That's basically what RG told me when I bought my new Tamora. If, after 2000 - 3000 miles, you can't cain it you have to ask yourself "why?".

Of course, I don't know the answer to that question as I'm a mechanical know-nothing! AND....I've had a few beers.

[grumbledoak]

1000 miles should be enough. Just don't 'nail it' from cold.

[tobeee]

I'd call Str8-six and ask their opinion. They will know!

Good call.

RG told me that I should gradually increase revs after my 1000 mile service. For first 500 miles only gie it another 500 - 1000 revs, next 500 miles similar increase until about 3k open up fully.

[Tangoed]

I had a rebuild at Power, I was told to run her in for 1000miles and not exceed 3000rpm. But on occations after 500 miles, I was told I could take her up to 4000rpm if I wanted.

After an oil change at 1000 miles and check the valve clearances, I was told shes good to open up at your will. No more poodling around.

[S6 SFX]

Jason (STR8six) told me to keep my rebuild below 3000 for 1000 miles and to vary the revs, etc. I had an oil change and valve clearance check at 1500miles (all perfect) - after that Jason told me I was free to give it some welly. I still keep below 3000rpm until the oil is 65 degrees though, then unleash the fireworks, and my change up lights are set at 5000rpm (my choice). I've had conversations with Jason though about the stress levels in running the engine in the 6500+ rpm range. I don't need to, so tend not to.

[Whitey]

S6 SFX, what did Jason say about running the engine above 6500rpm?

[Jim Green]

CONTOVERSY...............lol


So.......we run our rebuilt engines in for up to 4000 miles not exceding 3000 - 4000rpm and taking it easy. Bearing in mind the average mileage for some people on here is only 3k a year. By the time we actually get to enjoying them, and using them for what they were designed for........and actually opening them up properly, the warranty on the rebuild has ran out ! ! ! ! LOL. Might as well have left the knackered engines in and poodled around posing at 3000rpm and saved 6k.

Sorry, but when mine lets go I'll be going down the V8 replacement route. The RG Finger Follower Free Engine looks to be the answer to most of the reliabilty problems, but at what's basically 9k, I'm sure I could put in a reliable and light V8 that would produce 400bhp plus, with no reliabilty issues. OK....I know it's not keeping the car as it should be, but I want to drive it (Fast) and enjoy it, not molly coddle it for 4000 miles and then worry about if it's going to let go at anytime with no warranty left on it.

You could keep it all pure TVR though if you put in an AJP V8. It would be lighter and tuneable to 400+ bhp with better longevity. Keep your eyes on Ceejay & Trackcar (PH names) who are racing a T350 in the challenge series as next year they are will be running an AJP V8 in the car. If I ever need another rebuild and I'm not satisfied with the longevity of the S6 solutions out there then this is the route I will be seriously looking at.

Nothing that isn't common sense - the highest stresses are put on the balance of the SP6 engine at the highest revs. Running the engine to its max physical potential will dramatically increase the chances of having to have it rebuilt, as most race teams accept, but it is the nature of what they do (rebuilding after relatively short high intensity mileages). If I remember correctly, Jason's point was that for road use, why would you need to be up in that rev range for any sustained period of time? You can prolong the life of your engine massively with simple warming up and common sense, and still get the full enjoyment of the car. If you want to track the car and increase the stresses on the engine, then don't be surprised if your reduce its life. Probably no big revelations, just good old Lancastrian common sense!

Morning, yes he told me the same thing a few years back, I just wondered if his view had changed with I'm sure his continuos tweeking of the engine.

Hi Jim,

You must be new around these ere parts!! le€t us know who will do a properly engineered all alloy V8 engine swap for 9K. The queue will be a mile long! (ok well maybe a handful of SP6 cars long )

I played with the same thoughts, of putting in reliable V8 power (as in a brand new LS7 engine), but in terms of price, it would have come to at least 15k to have the custom exhaust manifolds, engine mounts and everything built...

Totally agree,why should there be a running in period as long ad the warranty. It should be run in before you pick it up so as you have full enjoyment for the warranty period.

There not daft when they dish out 3 year warranties linked to mileage.

I had a rebuild last year from a proper engine builder and it was run in for me before i picked it up.

Come on you "TVR SPECIALISTS" we are not mugs you know.

Same here T450 - before handing over with new bottom end to me, they did 120 miles' bedding in routines for specific parts (for example full throttle high gear middling rpm a dozen times or so, to bed rings in) then straight onto Castle Combe track with instructions to build rpm up steadily each session to max.

For peace of mind, suggest just give STR8 Six a ring and check whether they can advise whether it was run in by them, etc.

You might be surprised at what one of the more well known specialists personal view is on running in.........f@ck all is necessary!

Jason has never said to me that he can make the S6 failsafe - but he has done a lot of work to address areas of known weakness to increase its longevity, hopefully significantly. Having been promised the world by Autocraft, I feel more relaxed now in the hands of a realist and consequently confident that my engine, shown some care and consideration will not suffer any catastrophic failure as all the known areas of weakness have been strengthened or removed. I suspect Jason's view is one of cautious pragmatism - underpromise, then overdeliver. It's a good strategy if you're running your own business.
