what size exhaust tube/elbow etc for my setup?

[CNHSS1]

in between melting turbos and blowing engines, yeah it was quick. i think they got a bit disillusioned to be honest, they ran an SS1 like mine but with about 230-240 brake and that was good, but all the time and effort not to mention money that went into the Sabre didnt really pay off. I think it was just a lack of development. There was so many 'urban myths' as to power out put, but some just didnt add up to my mind. Ive heard 400bhp bandided around although around 300-340 with the T34 was the last figures i heard before it was sold. i suspect it was running 280-300 reliably but the T4 turbos and big boost were killing engines and parts left right and centre. Not a problem when a car dealership and factory was backing the car i suppose.
It was finally retired about 6-7 years ago and has passed thru a couple of owners since, before being sold to a current sprinter who blew it up testing it a month after buying it! a new modern spec engien should see it more reliable and quicker tho.
The only track i have data from that ive raced at and it did, my car was quicker ound the lap although slower max speed over the start/finish line. Rumours of when it ran full slicks and big boost, it ran 1.5 secs quicker than my best time so ive got summat to beat i suppose ;-)
