Stealth Cam Fitted Today
Discussion
Today I had the pleasure of meeting Rob Robertson who fitted one of his Stealth cams to my Chim.
For anyone considering a new cam I can thoroughly recommend the Stealth.
To be honest I was surprised how good the low rpm drivability is on this cam, the car pulls without any hesitation from 1500 rpm no problem.
As the revs rise it just gets better & better.
From 3,000 rmp on it really starts to sing, 4,000rpm to 5,000rpm is awesome
Top service from Rob & Ray too

Hey Quinny, your right thats exactly where Rob put it, uncanny.
Rob told me it was you that christened the cam "Stealth", never knew that.
Your previous posts on how happy you were with the Stealth, plus Rob's advice helped me make my decision to go for this cam.
To be truthful I still had a little concern in the back of my mind it would be a bit too radical for my taste.
I really needn't have worried!
I can honestly say there would have been absolutely no need to have gone for a milder grind, the Stealth has proved to be surprisingly tractable.
And it really delivers in the top end too
In fact I got up at 6.00am this morning so I can go for another blast, well I'm sad like that

Not yet Dom, but that will come.
I do have a before graph that showed the car was seriously under performing, I just need to get it on the rollers now the Stealth is in and I will post the before & after results for all to see.
But just driving the car its obvious the difference the cam has made is dramatic, but you must temper this with the fact that my car was a bit sick when I arrived at V8 Developments.
Rob & Ray sorted a few other bits on the day, including putting right my abysmal effort at fitting the slightly shorter Vauxhall Vectra injectors.
When I say a few bits, what I really mean is lots of bits!
They didn't just fit the cam, followers & timing chain kit like you would expect.
They did all this too:
YES, THAT'S £600.00 CHEAPER FOLKS!
I can't recommend the boys at V8 Developments highly enough.
I did 120 miles in the Chim today just because the sun was shining and visiting my clients in a Toyota Prius is so dull.
The car is transformed, it runs so smoothly, fuel economy seems improved & best of all it revs like hell
Getting Rob to fit his Stealth cam is the best thing I have done with the car so far.

They did all this too:
- Steam clean inlet manifold
- Remove & refit all eight injectors that were badly seated (engine running on 7 cylinders when I arrived in the morning, that's another story)
- Steam clean timing cover
- Remove seized bolt from timing cover (required a lot of heat to free it)
- Replace various corroded bolts, free of charge
- Check oil pump for wear (all good)
- Uprate oil pressure, double relief spring fitted
- Clean, polish & deburr oil pressure relief valve plunger & seat
- Oil pressure increased from 35 psi to 40psi on the TVR gauge (probably more like a true 50 - 60lbs with a decent gauge)
- Rockers stripped from rocker shafts, rocker end faces deburred, flatted & polished on a surface plate
- Rocker shafts deburred & polished
- Fit missing cam retaining plate £15.00 (TVR had not fitted one to by car from new)
- Steam clean rocker covers & secure loose oil trap plate screws
- Drill out old snapped off stainless screw in rocker cover (hard as hell) & fit new dip stick retaining bracket
- Lots of other bits I didn't see because I was on tea duty (best not to get in the way of the experts)
YES, THAT'S £600.00 CHEAPER FOLKS!

Have your poor cold running issues gone now, or are you still trying to sort that out?
Hi Ribol, the cold start issue is much improved thanks.Its not what I would call completely perfected, the car is still very slightly fluffy for the first minute or two (really nothing to speak of) but most importantly the threat of stalling has completely gone.
I have replaced the ECU coolant temp sensor, injectors, fuel temp sensor & as we know the cam.
The injectors definitely helped but biggest improvement to the cold start over fuelling issue seemed to be when I changed the fuel temp sensor on the fuel rail.
The car starts & idles perfectly as it always did even when the fault was at it's worse, but I can now drive off on a frosty morning with out fear of stalling and the subsequent flooding issue that many suffer from.
The cam has only been in a week and as we haven't really had a very cold morning start since its hard to say if it's improved the situation further, my gut feeling is its made no difference to the cold start issue.
It has however transformed the performance
For anyone suffering the cold start glitch I would say its well worth replacing the fuel temp sensor, replacing the ECU coolant temp sensor made little or no difference for me.
The original Range Rover fuel temp sensor is ridiculously expensive at anything from £70 - £100, so I took a punt on a pattern part at £23.00 from Dingcroft Land Rover, worked for me
For anyone needing one just quote the RR original part No: ETC6661

I guess that would explain why I and so many people I know don't have the problems you were experiencing, there was something wrong.Its not what I would call completely perfected, the car is still very slightly fluffy for the first minute or two (really nothing to speak of) but most importantly the threat of stalling has completely gone.

As I posted somewhere before, these cars are never going to start and run like a 2010 Lexus but having said that if all is well they will "work".
Sounds like mission accomplished to me
