big bhp engine question

[ady]

any details on this 600hp one ?

[g11ary]

Any one have any pics of GT42 installs that have made this kind of HP please?

Hope its not another snide comment, most people probably only know of 2 in the uk, Gary Goodings and Clives, so probably no install piccys available.
Plenty have been worked on in Auz.
So although not been done here in the uk its is possible with this turbo, or do we think otherwise?
For those that want info on GT42\'s just go on here and search for them.
Search hard enough and there are some 700 bhp ones here, one talks of a 600 in a 12a.
Im sure if searched there would be lots on rx7.com as well.

Thanks Gary,

I can\'t believe I wasn\'t already registered to AusRotary!

Seems to me that this turbo is easily capable of some very powerful figures, but to get the most out of it, you need a fortified engine to take the boost - perhaps that\'s what is putting people off going for Clive\'s, knowing they\'d have to shell out another £3k for the engine work?  Or is it feasible to run low boost through such a huge turbo?

Here\'s a pic for the lazy This engine has produced 409 @ 14psi: -

No Gary, a straight question - there are A LOT of different GT42s available, I have one (below) simliar to clives and the one ross ran - but the only ones I\'ve seen on \'high horse power\' cars on the wonderful tinternet look more like the TA-style GT42 (bottom) compressor cover. 400 at the hubs at 13psi is indicative for sure! But I have no idea of the differences between them (not used the turbo yet to be in a position to wonder), hence the question...

AusRotary, they sure know how to do it over there dont they, :rollin Good old Pete!

Chris running low boost on a GT42\'s no problem you just need a decent wastegate/controller to keep boost down, only running 10psi myself at the moment.

Thats prob ok on 20b but might of thought that the tub wont be operating at no where near opt on a 13b, being a smaller engine it might be off before its on.
