after my last dyno (330rwhp) I was told my stock injectors were @ 100% duty cycle or close to it and that I was running rich due to the fact that they were running wide open. Their suggestion was to get 1300cc secondaries and maybe a pfc. My question is, are my stock (ported wastegate) turbos done as well? and should I do a single or try M2's twin setup? suggestions would be appreciated



Thanks

 

What boost are you running?



The stock turbos can be taken to like 18psi... Though they don't last that long...



You can run them on the street at 12-14lbs pretty easy...



I would look into a port job on the motor, injectors, and the PFC.



Don't be a rikki makes 11 second passes at 11-13 psi on the STOCK twins. You don't need upgrades...

 

Oh, and 100% duty cycle...



If you are 100%, and running rich, you still have life in the injectors. Turn down the fuel. Get a standalone, and get it tuned. At 330, you are prolly close to the max on the stock injectors, but if you are rick, you are fine.

 

stock turbos are good enough.... keep under 15psi and they should last a while. just get the bigger secondaries and a PFC and you should be set!

 

motor was ported and built @ KDR. From what I've been hearing it sounds like the pfc is the way to go (as opposed to the AEM unit.) Would you agree?

 

the PFC is a great unit. just need somebody to dyno tune it for you......... its awesome for the stock twin turbos and even when you go single turbo. quite a few of my friends have PFC's without any complaints. i like mine before i sold it to turbovr6

 

Go with the PFC. It's very popular now, and should be easy to get tuned...

 

If you get a PFC you HAVE to get a Datalogit. Without the Datalogit the PFC is very hard to tune. You can get a Datalogit for $299. If your running tight on money I'd get the PFC with NO controller which will save like $250ish then use that money for the Datalogit. Its much more important than the controller.

seeing as how I've only heard of the datalogit but never used one, does this mean I wouldn't need a dyno to tune it. And if so would I eventually need the pfc controller to make changes?

 

i believe that you would use the datalogit in conjunction with a tuning session on the dyno. it is a more advanced viewing and source for the capabilities of the PFC>>>>
