hello,i have CTT 05 with these aditional parts :Gemballa exhust,fvd catbypass,ipd plenum, upgrade intercoolers,evoms intake and ecu software and i want to fit turbo chargers. what turbochargers can i fit,how many hp will upgrade with no problem these and how many cost?Thank in advance.

 

That's the question...how much are you willing to spend?? if money is not an issue...name your horsepower.....just my imho. ..and before you do all that reseach and see the max capability of you stock turbo first..

I believe EVO Motorsports has some HP options with upgraded turbo's for the Cayenne... up to 700HP I think! Check with Alex from Sharkwerks, he can give you some ideas on how to spend money.

 

While we're talking about it, anyone have some specs on the stock turbos?

 

hello, the oem turbos are rhf5 and i want to fit bigger with no other modification to take 600+ hp with the other parts that i have allready change easily.

Which model are the OEM turbos? RHF5?

 

Can i use abigger rhf with no other mods.?

 

The stock turbos are k16's, why not upgrade to billet k16's?

 

Tell me the different between billet and the oem ! I am afraid that if I will have many problems if i willupgrade my turbos I will have problems in the oil,water, so I have already order a primary catalytic 200cell, upgraded intercoolers,ipd plenum, evoms intake , and I have already fit fvd cat bypass, gemballa exhaust and when I will finished the fittings I will play with the ecu flash a lot.I believe that all these parts will be my final with no other problem fitting

 

Sorry no fitting tuning

 

I am afraid that if I will have many problems if i willupgrade my turbos I will have problems in the oil,water,

then just do a hybrid(bigger compressor sides).....

 

With upgraded(hybrid) turbos these cars can get around 600-620hp and 800-850nm to crank maximum, for more power modification on fuel system is must and thats not so easy on these cars, but of course can be done

 

RHF5 on 4.5 cars. 381 CFM
TD04 on 4.8 cars. 529 CFM

Looking at the amount they can flow 381 CFM each I would say you will be lucky to get much over 530-540bhp on the standard turbos, unless they have an hybrid compressor wheel??

 

This thread died. Let's resurrect!

1. Are the turbo manifolds different on the 955 and the 957? I imagine they are, but if not, just swapping to the TD04s would be an inexpensive upgrade.

2. If different, it should be fairly simple to have the RHF5s modified to flow better. A brand new turbo is only $850 from Suncoast. Does anyone have any ideas on that or someone who has already modified or "hybrid"ized?
