Update on some recent upgrades
Discussion
Hi All,
Just wanted to give you a bit of feedback on some upgrades recently had done to 'Burt'(1999 4.5 63k)
1. Emerald ECU
2. Intrax suspension (plus poly bushes all round)
3. Quaife ATB diff
Had these in for about 3 months now and they have completely transformed the car, whilst the remap didn't produce anymore power (still stuck at 375 bhp) the delivery is alot more progressive and smoother as you press the 'fun' pedal, which helps me not to make so many mistakes!
The Intrax I know are expensive but they are amazing, car feels more balanced and poised, you get great feedback and has really increased my confidence in driving the car at speed around bendy bits.
The Quaife ATB diff was a nightmare to get fitted requiring being sent back to Quaife for them to tinker with it before it would fit housing. I also needed new drive shafts so I was waiting for about 6 weeks to get it in the car. Was it worth it? Definitely! This is an awesome piece of kit. On a full bore run, red lining at each gear change the grip is incredible, not the slightest hint of a rear end wiggle, granted in the wet this may be different but we don't like the rain so we don't play out on those days.
In essence then IMHO 3 upgrades that really do work together to transform the cerbera.
Can't wait for my next track day to see how much time I can now trim

Funnily enough, my car goes by the name of Bertie The Intrax I know are expensive but they are amazing, car feels more balanced and poised, you get great feedback and has really increased my confidence in driving the car at speed around bendy bits.
Ive had the INTRAX on for 2 and a bit years now. They really are a classy piece of kit. Absoulutely convinced that on a couple of occassions they have been the difference between an "OMG I got round the corner" moment and an "oh s
t, I hit the barrier" moment

Whats the difference between the standard diff in a 4.5 and the one you have fitted??
I'm not the best at explaining technical stuff but there's an interesting link about the Quaife ATB differential and how it works here http://www.quaife.co.uk/What-is-a-Quaife-ATB-diffe...The reason I change it for the hydra trak was mine wasn't working very well and thought well its 10 yrs old technology, there's got to be something better and boy there is!
Regarding whats best Nitrons, Ohlins or Intrax, there all pretty much the same Ohlins where 30 quid more expensive but I liked what I heard about Intrax particularly their performance and reliability have a look at http://www.intraxracing.nl/?lang=EN. Incedently I did have nitrons fitted to car originally but they where tired.
FUBAR I did read your comments about them when you got them so that helped lots cheers

Our Hydratrak (11years/80k miles old) had also given up... though we reckon it may have given up a few years ago, so we cant really do a fair comparison, so its interesting to hear your thoughts on standard vs ATB. 
very interesting to hear about your experience with the Quaife. Some of the early Cerbs just had a standard limited slip diff, sounds like as our cars get older even the standard LSD diff is better than the hydra track, or at least more predictable.
How much was the Quaife, couldn't find it listed on the website?

Think I paid just under £800 plus fitting, but you may also need new drive shafts, apparently there are lots of different types and lengths and can be pot luck what was factory fitted. If you interested Scole Engineering went through the pain with me. Quaife don't manufacture these as standard for TVR but I believe they did a bulk tool up sometime ago for some TVR owners (do a search on Quaife ATB in all TVR forums).
It's a pain but its worth it.
