Noz Posted April 13, 2012 Share Posted April 13, 2012 Evening all, was wondering what highest figures people have had with 69mm turbo's. I know it depends on A/R's so I was looking at turbo's with .68 A/R's though I know thats not a big housing for tall figures. Know a few guys run T61 turbo's with similar exhaust housings.

V8KILR Posted April 14, 2012 Share Posted April 14, 2012 I have a T4 MasterPower T70 (69.1mm compressor with AR 1.00) and I have made 450rwkw (603rwhp) on a dyno dynamics dyno with the Getrag 6 speed on 98 octane pump gas with Nulon octane boost. This equates to around 710hp at the engine. I'm pretty sure that with more tuning (and getting the boost to hold) it would have made 500rwkw. The turbo is rated around 800hp. I would expect you could get 400+ rwkw on the 0.68 AR. Link to comment Share on other sites More sharing options...
Noz Posted April 14, 2012 Author Share Posted April 14, 2012 Sound's like 600bhp would be pushing its limits then. May have to consider a different housing for the future. Thanks mate Link to comment Share on other sites More sharing options...
