The F1-X V is alive btw sticky...numbers to come soon :) 1xxxwhp

Hey guys, that was my 2013 Santorini Blue E92 M3 at Bimmerfest. The Harrop kit was installed earlier this week, still needs to be tuned which should be happening within the next few days. I will try to keep you updated as best I can.

what did he say about the meth?

This isn't something that will stack up against a 2.9 or 4 liter whipple. It's a 1.7 liter blower, comparatively small. This is something for low 500's at the wheels. Not a big power platform. It's just going to make the car a hell of a lot faster and more enjoyable. It gives the S65 a lot more torque down low. Regarding stacking up against a 4.0 liter whipple V that would be my YSI setup.

That is correct as far as I know. I'm probably explaining what I mean wrong.

It won't cure it. Glad you read what DBFIU said about meth in the thread I created though. You really need to stop talking as if you are an authority. You're making little strides keep going. Do more reading as you have been.

I'm also gonna attempt installing the downpipes at a much more competent shop after to see if the smoking problem is gone.

You can't change duration with VANOS, correct? You can only vary the center line I thought.

Plugs were perfect, no oil whatsoever

i cant wait to see the results....should interesting to see how this stacks up against a V stock, 2.9L whipple, and 4L whipple :)

what pulley do you have on and awaiting install?

Interesting. I don't think a leak down/compression test could diagnose valve stem seals. You would have to pressurize the head port with the valve closed. What do your plugs look like. I would think if all the oil was going through the combustion chamber, your plugs should show evidence of that.

There still is no twin screw and I don't know if there ever will be. You don't seem to understand but that's fine. The technical details for why a positive displacement did not exist and would be difficult to do were all discussed. The reason this works now is due to exactly what I wrote in my post on page two: Those were the two ways to do it. Nobody did it by going to a single throttle body and nobody had a manifold for a positive displacement that would fit behind the ITB's. Well, these guys thought out of the box and made one. Now at no point did you suggest a solution or any reasoning for why it may happen or even show an understanding of why this is difficult. And this is now out yet btw, there is a ton to do. Great thread though for people who want to actually read some technical points.

i dont see anything a small shot of meth wont cure hasnt stopped you in any other thread in which you have less experience..

Results sound really promising! When you post the charts be sure to also throw up a log of boost, timing, and duty cycle for analysis.

i find that very hard to believe, as i had that issue, and no problems shifting.. when it would limp from FP, it would be an engine malfucntion, not trans

I would think that reducing the duration would help, but then you would give up hp. The easy solution to me is ramping up boost pressure. A very popular LSx tuner in my area by the name of Dan Maslic, who has written books on tuning, says hes is a fan of doing this to keep making power in the upper rpm range on engines that don't flow well.

considering it is relevent again with a new option, people may want to see its been discussed before., so what i quoted was personal choice, but it needed to be bumped also, i was going to quote the best information you provided in this thread, but decided not to: in reference to my comment about a TS blower for the S65..

Just bought myself the Porter Cable 7424xp in a kit that included: 1 CCS Orange Light Cutting 5.5 inch Foam Pad This light cutting pad is designed for the removal of mild to moderate swirls and scratches and light oxidation. This is a dense, closed cell foam that effectively levels the edges of scratches until they become flush with the surrounding paint. The orange light cutting foam pad is the most popular pads for the Porter Cable 7424XP and it works on the most common paint imperfections. 1 CCS White Polishing 5.5 inch Foam Pad Less dense foam formula for the application of waxes, micro-fine polishes and sealants. This pad has very light cutting power so its perfect for pre-wax cleaners. 1 CCS Gray Finishing 5.5 inch Foam Pad Composition is firm enough to withstand added pressure during final finishing to remove buffer swirls. It has no cut and will apply thin, even coats of waxes, sealants, and glazes. 12 oz. Pinnacle XMT Fine Swirl Remover #2 Pinnacle XMT Fine Swirl Remover is a blend of mild abrasives and lubricating oils that remove light to moderate imperfections on aging paint finishes. If your vehicle is not new but has no severe paint damage, this is the swirl remover for you. It removes light to moderate imperfections like swirls, mild scratches, and light oxidation without reducing surface gloss. You will not need a finishing polish. 12 oz. Pinnacle XMT Carnauba Finishing Glaze The gentle cleaners blend away minor flaws - like spider webbing, micro-marring, and overall dullness – to increase depth and clarity. At the same time, a layer of carnauba bonds to the paint surface to further enhance the dynamic shine created by the glaze. What can’t be removed with the cleaners is filled in with carnauba to create a smooth, flawless finish. It’s perfection and protection in one! Use XMT Carnauba Finishing Glaze as the finale to your detailing process. as well as a 12oz free sample bottle of another swirl remover. Totalled $192. Im also ordering some CG's soaps/polishes/compounds to go with it

Bump for BrenM3 or M&M

Lol, I was just as confused. It's funny because it's not that complicated. 8000 rpm = 133.3 rps = 266.6 strokes per second = 3.75 ms per stroke. Concerning overlap at high rpms reducing cylinder pressure, wouldn't that be something you could minimize by tuning the Vanos system for your particular high rpm application? This question is basically for my own edification.

Yes, and unfortunately very addicting. When I had my 2003 SVT Cobra Mustang, MPG varied wildly depending on how much I was pressing down on the go pedal. ;) Avg: 16 MPG around town. Best: 26 MPG from NY -> MA @ ~75 - 80 MPH Worst: 7.5 MPG around town. :-D As others have pointed out, as you have a fixed unit in which you are compressing, you are generating a bit of heat. The way to make more boost is to spin it faster, which reduces efficiency, heating things more. A air-to-water intercooler is ideal in these setups, but require custom intakes, which if I read it right, has been done here. It should make the car even more of a beast. -Matt

little update. Code that was being thrown was a fuel pressure sensor. We replaced that and no more limp mode. We yanked the DR's off and tossed my street tires on and zero shifting issues now. ALTHOUGH I have been using the shifter and not paddle for high rpm shifting. We are thinking it may be something related to the paddle/steering wheel some how. We are gonna do some more testing this upcoming wed at the track and see if it resolves the issue.
