    Adam - don't quote me on this but I think it's around 500rpm difference.

    Sorry Bill. badly worded question there.

    What i was trying to say is, would an equal length mani collecting at the flang for the turbo provide a more constant flow in to the turbine, and this would then reduce lag ?

    seeing some non equal length mani's, i wonder how efficient they really are at maintaining / directing the exhaust gasses as efficiently as possible.

    But then considering the engine rotatiing @6k rpm, (100 rp/s) im sure gas flow isnt as important as i once thought ?

    nope. 0.82 and 0.86 hotsides will always spool slower then their 0.6x cousins..
    its a minimum of 500rpm slower spool from what I have seen..

    its a balance of power delivery vs your operating rpm range.
    pointless (imho) loosing 500rpm spool when you dont have an engine which can explore higher rpms if its not been built to use them.

    mine, as en example is getting going from 4500rpm, banzaii from 5krpm, but also revs to 9krpm when i let it. 0.82/gt35r. If you loose initial spool, and only have a low 7krpm limit, you need to see if you are likely to fall off boost in any of your gears.

    the octavia I had, had a shocking spec turbo on it which literally would'nt spool until 5krpm and had a low rev limit of 7300rpm which it just head butted.. and you fell off boost badly between gears.. It was supposed to be a GT3071/0.82 and I replaced it with a GT2871/0.63 which drove much much nicer.

    regards
    bill

    When I eventually get round to fitting my 3071 with .82 A/R i will report back - at the mo head work is OEM so limit is also going to be around OEM. Would like to test after doing headwork to see whether or not I want to change the turbo - time will tell :

    On another note Bill I think I'll get the Jetex off you
     
  7. What sort of figures are you hoping for?

    I see you have had a 6235 then? Similar spool, 30bhp more.

    Way too much for the beezer though ! :happy:

    the 35 was more power than traction..
    but in turned down boost its not work very hard (my theory) and I have uber power left to squirt down the straights when needed during the race

    Have read this from start to finish and what an amazing journey you and that car have been on although it has been very rocky at times :(

    Cant wait to see its next reincarnation may even take a long drive to come and see it in action, have you ever thought of doing passanger rides sure you'll be able to recoup some of the costs as i sure would pay for a ride in that beast ;)

    All the best sure it will be perfected in the near future
