Mongrell, as in signature 226 rwkw auto.
when you have done plenty of klm's then get yours on dyno they seem to take a long time to fully loosen up...
mine, rays 229 rwkw man, rodderz 240 rwkw man, and rods 290 pursuit auto has 268 rwkw have all been on the same dyno..

Just be wary of the dyno figures, some places will read high, some low, usually high as thats when the customers are happy. Those who attended the APS tech day were shown just how easy you can get a higher kw output and fudge the figures with nothing to do with the car, only correct/incorrect dyno practises

the flange plates are all pretty much standard...

So is ray running standard cats then??

Does it make any difference performance wise running the 2.5 inch collector into a 3 inch pipe or vice versa???
no Ray is not running standard cats they are aftermarket cats.
i am not sure what brand you might have to ring Tallah made zorsts in Melton Vic..

Mate you got yourself a beauty, :hy: it would be good to see another dyno in about another 10,000k's would be up there with a couple of gt's.

How does it compare with the last ute?
