Re: Lucas 14CUX on a 4.6 ?

The CUX Hotwire ecu has lots of scope TVR used them from 4.0 to 5.0 displacements (yes even the 4.6) if you need it remapping to suite I recommend http://www.kitsandclassics.co.uk/ and wont charge a kings ransom unlike some, lots of satisfied TVR owners 8) dont waste money on a generic performance c...

Re: 3.9 later intermin Serp Engine project

X bolting not necessary IMO unless your building a balls out screamer or aiming for big power numbers , no need to change main caps on many 3.9 int blocks they already have the full width caps fitted block and caps just needing jigging and drilling for X bolting :wink:

Re: stepper motor - alternatives

Bosch 2 or 3 wire get my vote older Volvo Saab BMW GM etc , if you run a big cam ign scatter spark dialing in lots of advance etc wont be enough for warm up so some kind of ICV is essential in some instances, I agree with Dave the Hotwire stepper is a pain in the arse and often erratic in its action...

Re: Fuel pump.flow pressure

Lucas Hotwire stock pressure is 2.5 BAR if your using just 2 BAR that may well be your misfire from an over lean AFR (dangerous for the motor) :(

Re: I've got a chatty engine.

Those bolts should be at least thread locked or preferably lock wired :) witnessed this problem more than I care to remember on the RV8 :? combination of heavy pick-up pipe and engine vibes all contributors to this issue with the result .... oil pressure woes

Vauxhall/GM Sagem 1588 inj's are a good alternative available newer and have a superior spray pattern to the Lucas Hotwire disc style inj's , quite a few TVR Hotwire guys use them inc myself

Re: 4,6 Ltr with quad Weber power output

From my calculation, I'll get 9,75/1 when I fit 4,0 ltr pistons. I've calculated somewhere but can't remember exact, with thin gasket little over 10/1 and I feel about the max for this engine with fast road cams. I was hoping round 260 Bhp and seems like most agree. On the other side, I was in the ...
