local dealer : like the C turbo but with .48 exhaust side ( I think its too small )

http://koti.mbnet.fi/hi-po/pics/masterpower/ masterpower vs garrett
on here master power right,left,left,right

Yes, nice pics, but still no compressor maps.

No maps, no idea what to recommend

good product or not if you choose the wrong one you arent going to get the spool up you want or the power you want,thats why looking at a compressor flow map can tell you how the turbo is going to perform-finishes flogging dead horse-just buy it and tell us how it does

good thing is that my car is only summer/hobby car ... so maybe ill do the test and let you know

so, whats your opinion, on garrett turbos ? what should I use ? 400hp-450hp and I m gonna use : 599cc injectors, 3" exhaust, new exhaust manifold, walbro, fmic, etc etc .. kms engine management, or the original one... both are fine .. yes we can

re-read my post from yesterday at which turbo for 400 - 450bhp

http://www.atpturbo.com/Merchant2/mercha...tegory_Code=GRT this is what the local garrett dieler says, with the .78 exhaust side, splitted .

but the costs in Finland are 1449e !! so I can get 2 different master power turbos and still have money left . ... dont know what to do ...

Why not just email MasterPower Turbos, tell em u want to spend your hard earned money with them but will not do so untill you can see compressor maps for the turbos your interested in.

we have now tested masterpower. 58,1mm / 56mm .48 exhaust ( mp 810019 ) side. test car 155 Q4 . boosts very good . 3 gear 3000rpm/ 1bar. soon we get some RR results..

About the spoolup.

According to one of the largest (if not the largest) aftermarket turbosuppliers here in sweden. The exhaust side is what you look on if you want mess with spoolup. Compressor side has very little impact.
Exhaust side, a/r. housing, turbine wheel. etc.
As someone already mentioned. Its the exhaust side wich drives the compressor side.
I asked this because I had the same dilema myself.

yes I know that. before we get any results I was thinking somewhere between 3000-3300rpm spool up. ( looking about same size garrett turbos spool up )
