Racing Dynamics Headers
Does anyone have any experience with these and can comment on build quality? I saw Datastream18 has them on his car w the ESS package but is there anyone else?
I was thinking of selling my car but now decided to play with it a bit more. So I am considering the full TS2+ package (cams, +0.5 psi boost) but this requires headers according to my conversation with ESS. Given their response on the Supersprint stepped headers (in other threads) in regards to their tune, I am looking for other options. The price point of RD headers vs SS's make me pause on this purchase and ask around. I am dropping a 3.46 limited slip in next week and I am sure that will help wake the car up a bit more. |

Where did you get your 3.46 LSD? I'm looking at options for my 3.0i.
http://www.my330i.com/essreview3.php Under "Power" the author talks about swapping back to a 3.07 gear set because he felt his 3.38 was too much. I have a 3.64 open diff I'm going to swap in to my supercharged car (VF 6 psi centrifugal) to see how I like the ratios, and then have a diff built from performancegearing.com with an ideal ratio. The Supersprint Step Headers are an M-only thing AFAIK. You'll want to budget for a new clutch, and perhaps a lightweight flywheel for a little more performance.

Dan @ Diffs Online - he came highly recommended and by my experience justifiably so.
I already have TS1 installed with TS2 upgrade on order. Now I am thinking that I should just go straight to TS2+. |

I've heard great things about Diffsonline. They are a bit more expensive than Performance Gearing, but everyone seems very pleased with them. Congrats!
From what I've been able to dig up, headers + cams will net ~30 whp on their own. The cams are where the power is (20 whp) while the headers net about 10 whp. Headers and cams will be my next performance upgrades.

It's going to be difficult to make it through the differential break in period - limit of 85 mph and no hard shifting for 1200 miles, but I think it will be well worth it.
According to ESS headers are needed with the TS2+ due to the increase in air flow...however I am asking ESS if I can do TS2 and the Cams and forego the headers. Should be a nice result of around 345 hp (DIN) and 330 lb ft (my estimate). |

I would expect more like 365-370 for a TS2 with cams. Very jealous!

Well I spoke with ESS and if I read the response correctly I can only do cams w TS2+ which requires headers. Doesn't make much sense to me, but they are the experts.

So basically suck it up and fork over another 2k or just stick with the TS2 kit and headers. For me an extra 50 hp isn't worth 2k, but I'm a cheap bastard. IMO just stick with the TS2 kit, you will absolutely love it! I do!

Understood. ESS says their HP number need a 15% loss correction factor. I have the 2.5 not the 3.0, so I will be a little weaker than yours....but still fun! How do you like the headers???
The cams are on backorder |

VAC and possibly Schrick make FI cams too.

FWIW, I stumbled across a post about the history of Racing Dynamics over on e46fanatics. Apparently there are two companies called the same thing.
