Rebuilt Power!
Discussion
I stripped my engine down to find a oil leak and ended up taking it out! I still have nightmares about the manifold bolts! I then decided to get some upgrades!
I contacted V8D and sent them my heads for stage 3 upgrade and inlet manifold, trumpet base, plenum for opening up and shorter trumpets. Their work was first class and plenty of great advice as well.
I replaced the cam with the std TVR Power one as Dom convinced me to do this to keep good torque from low down (this was a great reccomendation.
For various reasons I ended up contacting Warren at TopCats to collect all the bits and rebuild and install the engine and they did a great job and again some great advice. I then ran it in and had the torque flow kit from Eann.
It was running lean and the injectors were maxed out so I changed these for Ford Motorsport 24lbs. When it was running lean it was actually faster but as I track the car I knew it would be a short engine life running lean!
Been to the RR and its kicking out 334 HP and 352 torque and well pleased with this as its smooth and pulls from low down.
When I add up all the bills, time spent it may well have been a better option to run it up to Dom at TVR Power for one of his upgrades but at least I know that car a lot better now.
I have to say we are lucky to have some great people at different TVR specialists who give great advise and many thanks to everyone who helped me, now just need to get it on the track and show some of those modern machines what a traditional piece of engineering can do.

Well done Paul 
!
Similar work just completed on mine with very similar results.
Let me know when you're doing a T/D, it would be good to compare.
I am doing Snet on the 29th.

I have tended to stick to Silvertsione so far as I live 30 mins away and I mainly go to evening sessions from 5.30 - 8pm in the summer. I will let you know when next going up. Where did you get your roll bar from as this is on my list!

Cool. Good power there!
I bought my Chim from TopCats! Warren is a great bloke and their rate is very reasonable.
Venture park is interesting isn't it!? Think it used to be an RAF base
Yes top bloke and they always have great cars in there and run some top spec cars for different race series. They also put on some Gaz Golds and didnt charged to reset it when the suspension had settled down. I bought my Chim from TopCats! Warren is a great bloke and their rate is very reasonable.

The venture park was a rocket testing site for many years and was one of those sites where no one was supposed to know what was happening there behind closed doors!

Where did you get it on a rolling road? I have just had my engine rebuilt (just standard 450) and after it is run in I am keen to see what power it is putting out.
Cheers
I went to Surrey RR in Chobham, They are on a former weapons testing site (What is it with TVR people and military sites!) What have you done to your engine?Cheers
Cheers

From a 4.6l..?Those are fantastic figures - the torque is astonishing for a 4.6....
Cheers
Hi Paul, I wondered when you were going to post these figures.
I had the pleasure of following this car onto the rollers and I was very pleased when it didnt disgrace itself.
It would be a lie if I said I havent thought about doing some engine work on mine since seeing your resluts. Very tempting, especially as you have both got good results with this persons work on the heards

Hi Graham, Your 240 bhp from a 4 ltr was a great result and the boys in the jap cars that were at the RRoad looked impressed with the noise and the BHP our cars kicked out!I had the pleasure of following this car onto the rollers and I was very pleased when it didnt disgrace itself.

Hi,Cheers
Mine was just a full rebuild (done by Str8six). The heads had warped a little (possibly due to overheating when Otter switch failed) and water was getting into oil, plus Cam was very worn (my car has done 79k and i think it was on original Cam), Valley gasket had bad leak, various other oil leaks so just went with a full rebuild - Just with a standard 450/500 Cam which they recommended as being best for the driving i want to do (keeping torque low down and asy to drive through town etc).
Had lots of other work done at same time, but nothing that would affect power really. Will be interested to see what power it puts out with everything standard. Wonder if it will be 285 or better? (think that was original TVR quoted figures)

The roll bar is a TR Lane item.
He made it bespoke and now has a template to make others.
Be aware of other bars that are not high enough, these fit right under the top of the roof.
Let me know when you are doing a T/D.
