Re: New book?

Hi Jim , my mates are patiently waiting for the nine copies that Richard ordered from you . I believe you might have to do another run of prints once the word gets out what a good mine of information is in there. Im sure once they have read the books and posted on FB or where ever they will be a ano...

The old trick you taught me :) I will have a blanking gasket which i will use to switch banks ie .. one to left and one to right . This will separate it totally . Will keep you posted...

Re: Project 2 : front mount SA GTV 3.0 - Sei diff

Hi Pieter , I would have thought deflecting noise into tarmac could amplify it. Not sure why I thought that as it could result in destructive interference .. .. noise reduction . I understood the exhaust on the 155 DTM were turned up to reduce noise and keep the power they achieved . I have bought m...

Re: Hello from relocation to UK with my two South African GTV6's

Finally some good weather combined with Classic Alfa Trackday at Goodwood. Unfortunately my GTV6 trackcar failed the DB test even with three silencers on the side exit pipe . I think the big bore “bass” is just to deep ! I was 102 db already at 4000rpm on a 98db day

Re: Project 2 : front mount SA GTV 3.0 - Sei diff

Summer is here ! Cars are out. I have been working on another version of a side exit with two long straight through silencers with twin dual silencer. I think this should beat Goodwoods decibel meter !

Re: GTV6 3.2 24V

Hi Pieter
How did your track day go as you mentioned one was coming up . I see Extreme tuning exhausts also do headers for 24v that don’t come upwards like yours but also merge in one just past the engine mount . Any sound clips ?

Re: Alfa GTV 916 2,0 V6 TB bring back to life after 12 years

How has the final dyno session gone? What type of oil are you using in that motor ? Do you have a reservoir for cold oil to run back into turbo once you switch off . I saw this on a some factory Alfa turbos in SA

Re: Alfa GTV 916 2,0 V6 TB bring back to life after 12 years

That’s a serious amount of work ! Out of interest what is the size of the valves on that head .. not that it makes massive difference with forced induction. We’re all exhaust tappets worn all juts that one ?
