I agree that the fuel line in this case may not make a difference. The point was that without monitoring you will not know if your changes are making a difference and it is also dangerous to make changes to the fueling system in the blind. Glad you found the problem.

scboost

I agree. I bought this car pretty heavily modded. The fuel pump was out so the kid pit this one in the day I picked it up.

I really appreciate everyone's help and concern here.I have some really big plans for this car and ill let you guys know along the way

C3Duece

glad to see you found the problem and looking forward to your updates. BTW...hows the ole girl pull with that 61mm spinner?

Pewterslk320

Glad you found the problem, it was tricky.

scboost

It pulls great!!!! I test drove a c32 with 65mm and tune prior to getting this car. Let's just say the 65mm pulley car felt stock compared to this one.

Im hoping to p&p heads and kompressor at steigmeirer (the mustang guys) like a srt6 guy did. Hopefully that will lower boost where I can stack with a slightly larger crank pulley.might have to be custom like 172mm or something along those lines to stay under the 25psi mark

Lenin

Why 25PSI mark? The car uses a 2.5BAR MAP sensor which = 21.5PSI at sea level. When you start a new thread, I'll add my input there about running stacked pulleys and the rest.

Lenin,

I think 55K using the same 2.5 bar pressure sensor with 32K, is that correct...??

ZAYED,,

scboost

Stoked

Lenin

Correct

cm60k

Thankss Lenin,

According to the EPC, MB provides many #s of that pressure sensor,

"004 153 31 28",
"004 153 33 28",
"005 153 72 28",
"006 153 14 28",
"006 153 16 28",
"006 153 98 28",
"007 153 00 28",
"008 153 44 28",

do you know if all these #s comes with 2.5 bar...??

ZAYED,,

Lenin

Don't know about all of them but I know that A0061539928 is 3 bar.

cm60k

Good point, "99 28", is for CDI's Engines isn't..?

does anyone with 32k or 55k goes with 3 bar, then tune it....??

ZAYED,,

Lenin

Yes, it is for the CDI Turbo Engine. Don't know of anyone that has a tune for it. RobertAMG installed it without a tune. Not sure of his current results but I think the initial reaction was negative. An SRT-6 guy from Sweden claims that he has a tune for this MAP sensor installed but would not give the name of the tuner. And now he is having problems. CEL P1107.

I see, Thankss for the info...

scboost

Lenin can't we use a voltage clamp??

Lenin

You can but then the signal is not scaled correctly. Both sensors operate at 0-5v. So, the same PSI in the new and old sensor will translate into a different voltage readings and will confuse the ECU. The voltage clamp will only prevent the overboost CEL. More boost is not necessarily a good thing. You need to have the right cooling mods to maintained the ideal efficiency pint for the SC. Look at dragtimes.com and see how many cars are running 185mm pulley and where they are in the 1/4 mile rankings. Car#1 has top mounted intercoolers and car#2 used methanol injection. Car#3 used a 178mm pulley and car#4 used a 181mm pulley.

scboost

Good point..but..... What if you want to go faster then them?? Where did that one guy get the top mount intercooler?

raf12690

I think pansu fabricated some custom parts. Not sure if he did for top mounts, but he made his own headers.
