Grazer Posted August 16, 2004 Share Posted August 16, 2004 I did the true twin conversion at the weekend following these instructions. I quite like the feel of it, although it's odd having to downshift to get decent power at lower revs! At the weekend I was hitting 0.9bar boost when I had been getting 1.1bar prior to TTC (with Nur Spec and CW restrictor ring). Today the boost was hitting 1.0 but with spikes of up to 1.5bar. I checked all the hoses (all 2!) and they were on, but the 2nd hose - from the pressure line to EGCV actuator - is quite tight and may be kinking at the bottom. So I have 3 questions! 1 - should the boost be the same in parallel, i.e should I be hitting 1.1bar 2 - what effects would a this hose being kinked have 3 - I have hit 1.5bar before - when I fitted the Nur Spec without the CW restrictor ring - and both then and today there has been no fuel cut. Does that definitely mean there is a FCD fitted? Where would I look for it? All opinions appreciated Link to comment Share on other sites More sharing options...
Grazer Posted August 16, 2004 Author Share Posted August 16, 2004 I've just swapped back to sequential as I don't like 1.5bar of boost Anyone got any thoughts? Link to comment Share on other sites More sharing options...
tango Posted September 8, 2004 Share Posted September 8, 2004 Hi there, what is the term of boost spike means? cheers Link to comment Share on other sites More sharing options...
Ian C Posted September 9, 2004 Share Posted September 9, 2004 Boost spike is a sudden blip up to a higher-than-normal boost level, and then it returns to normal. What rpm is this happening at? My bet is around 4000... -Ian Link to comment Share on other sites More sharing options...
CJ Posted September 9, 2004 Share Posted September 9, 2004 When I changed mine to TTC I had exactly the same problem. This was despite the fact that I had a CW restrictor ring and had turned the boost controler off. I posted a thread up at the time and nobody could explain why this was occurring.

outatime Posted September 9, 2004 Share Posted September 9, 2004 Originally posted by CJ I posted a thread up at the time and nobody could explain why this was occurring. Same here, I posted up a couple of threads about it... silence Mine is only at 1 bar in sequential, but will easily hit 1.4 in parallel... Link to comment Share on other sites More sharing options...
