Xmas in January? Next mod on order (Headers)
Stated gains for M113 N/A engine is 15-20hp, at the crank, if my car was stock. My car is not stock.

Wish me luck as this is going to be a DIY install.
PM Vadim, he seems to be a very good guy and easy to work with. And he's one of the most respected tuners in the industry, from what I can tell.

You've had these EXACT VRP shorty's on for two years? What kind of gains did you see?
For what it's worth, I think adding these headers would complement an E55 airbox quite nicely.
Have fun and keep us posted.
Unfortunately, their printer wasn't working at the time so they couldn't give us our numbers on paper but if I recall, I was putting down 269hp and about 300tq at the wheels which when you account for drivetrain loss you get 269/.82 = 328bhp and 299/.82 = 364tq. Sounds about right, for my mods. I've been bugging the shop to get me the numbers but they're flaking out. At least I have something to go on.
I'll definitely do pre/post dyno for this mod.

ALWAYS bring a memory stick to the dyno. Get it on electronic file.

I have the AMG airbox in hand, just not installed yet. There have only been a few people that have done this mod, but have claimed a SOTP increase. I figure it couldn't hurt, so I'm gonna give it a shot. VRP now offers a slick looking "fang" intake, so I might give that a shot.
Will have the headers in a couple of weeks, then pre/post dynos. But then I'm going to Trinidad & Tobago for 2 weeks so I won't have anything to report until mid-march, if I had to take a guess.
Stay tuned...

Pricing will be good, trust me. You're getting the "Clayton is the mack daddy" discount.



Barry, your eyes are getting worse in your old age.
