How much power did you gain from just installing the headers?

From what I have heard the gains are in the higher rpm range.

Anyone else?

I have VRP's headers but I couldn't tell exactly how much power it added because it was part of the VR600 package. You might want to pm Blueknight (Nick), he installed the headers alone and could tell you his input. I'm positive that he definitely felt gains with it though. If you have any other questions please feel free to pm me.

I've got them installed on my W209.. definitely felt the power boost in the higher RPM range.

E-Diddy: My 2006 E55 was a test car for the original Floored Fab Shorty Headers that Victor began selling. The deal was a "great price" on the headers if I let them keep my 06 E55 for a couple of weeks for both Fabrication and testing & Dyno runs.

The net gain was 27 RWHP after the installation and runs on the Dyno.

Chris over at Floored Fabrication put the deal together for me. We did this back in 2007 and I was very happy with the results. I also added the 80mm TB and the Floored Fab intercooler kit.

so these headers dont add power in the lower rpm range like the AMS shorty's due? i hear the AMS adds about 15hp both in the lower and upper rpm range.

I have them. I would have to say that the power is across the rpm range. I added them along with a bunch of other mods so take this with a grain of salt, but when I compare my modded dyno chart to my baseline chart, there torque and hp lines are almost parallel from 3500 - 6400 rpms.

I designed VRP HEMs and now they are also available from us at FEDOR DEZYN.


As you can see they add 25-30RWHP. Due to boost being all across the power band, so are the gains.

Look for special pricing coming up later today.

I think the HEM will be my next mod.. just need to save up for them.

I like that they are easy to install.. and very easy to remove if needed.

I just ordered mine along with larger CAT inlets! Theres a guy with a 360WHP R32 coming down in a couple weeks gonna see how my little girl holds up!

Vadim,

The results on the dyno charts - is this with or without an ECU tune?

Vadim @ FD

Without tune.
