Thanks

Gotballs,

The performance gain of the downpipe itself on an S60 isn't very much because the downpipe makes the turbo overboost a lot.
So much that it runs in to the ECU's safety mode so a modified chip which DP adjustments is almost a must. The combination brings a lot of torque over a very wide band but below 2500 rpm with the 16T turbo there's not much to gain.
If you follow the "exhaust" link and click on the DP/Exhaust pictures you can see a highres image.

Hey Johann,
Nice site, glad you finally got more update on the car.
I wish I could have some time to do something up for my C70, too. Almost done now....just need to get the FPR thingy resolved, and if that works out and no glitches......But in the meantime, I'll just enjoy the IC upgrade and the car as a whole.Do some more write up about the car soon..we are running outta interesting Volvo enthusiasts' web site nowadays.

I think with FPR you mean the fuel pressure?

How about looking at parts from the S60?
The injectors of an S60T5 are 395CC vs 350 for the C70 so I guess the fuel system has higher output also.
I think I read something like 125 Ltr a minute but to be honest I don't have a clue about what it means

The fuel rail has what looks like a pressure regulator situated between the 1 st and 2nd injector but the problem is that I can't find a return line.....(Bwhahaha)

Yup yup

No need, I already got something aftermarket and a lot better of course.
No faith in Volvo parts.

Exactly, there's no more return line setup from 70 series up and newer. However, it looks like the fuel rail from the 70 series and the 97 850 is still the same...unless I seriously ordered the wrong one, long story. But yes, I'd have to put a fuel return line in the system to make my Aeromotive FPR work. And hopefully that will solve the problem with car running lean at high RPMs. We'll also check if the fuel pressure is indeed dropping.
It's funny how you ask most of the volvo ECU tuners, they'd simply tell you that everything is controlled by your ECU and if you are running lean, it's always software issue..never caused by small injectors and other misc hardware. Only if it was that easy...

But with the standard turbo's you do not have to worry about that to much.
I think the older T5's can handle up to ~315 EHP with the standard fuel system and the newer ones up to ~345 EHP
while I think the standard 16T can't reach that high without modification.
I think your mods are going outside the normal perspective of a "chip tuner" and outside the RPM range with which they calculate.

Johann,
Nice site, I am waiting patiently for my bov to be installed. Instead of using the stock pipe, I have my guy to make a stainless steel replica of it, so I can weld the HKS SSQV valve on it, should look pretty good. I will have some pics of it when it is done.

Well Johann,
You're a bad man.
And you have created a bad car.
Nice job!

Did you have to boost fuel psi? If so, how and to how many psi?
It really looks great. Those big wheels could use some big brakes...
What's next on your list?

Those are aftermarket types and do not come with the correct Volvo turbine flange.
You can't mount them to the exhaust manifold 1:1.
You could let them port and adapt the original turbine housing but I think this makes it more expensive compared to the original Volvo parts.
The 19T is a lot bigger capacity wise compared to the 16T but it's outside dimensions are the same.
The XXG compressors do not come with the integrated recirculation valave as far as I know so you have to mount a separate recirc. valve or a free to air type BOV.

Johann,
Maybe you miss my post in the S60 on Ebay thread, anyway, I want to know what kind of problem you experiencing with your Blitz? Slight bog down between shifts? Maybe because of the rich A/F ratio right at the shifts, hope I am "right on the money" regarding to your blow off valve problem.

Anyway, I came across some of the threads that some people, like me, want to have that nice wooosh sound when you shift, the loudest audiable valve on the market today would be the TurboXS Type-H RFL valve. With that, I am sure you can hear the sound in our pretty quiet Volvos.

The S60 is very sensitive on it's MAF and reacts to the air which goes out.
The "bog down" is not constant and when I have the BOV set to a setting when things feel ok it's just working to slow.

The "green" filter gives a good whoosh sound with the standard BOV.

I see, but it doesn't trigger the check engine light right? Hope not. I didn't know the MAF on our cars is that sensitive, smart Volvos shall we say?
On a side note, installing my HKS SSQV valve on my V tomorrow, going to weld it on a custom stainless steel pipe going from the turbo to the intercooler (the pipe abopve the engine.). Will let you know tomorrow night or Saturday morning on how it goes.
