Back where she belongs . Heading to the track for the weekend full report to follow . But briefly this is what I can say so far .
1.) engine : Much more midrange power and faster response ( must have had significant cylinder leak down ) . I'm sure the response is the result of the lighter rods and Pistons combined with faster rise of boost levels in each cylinder due to the tighter seals . The top end 7-8 k in gear is faster than my tuned TT M6 , you can see feel the head work here as it pulls hard to fuel cut now . Just a massive improvement in driveability and performance of the motor . 2 . The Diffsonline rebuilt Transmission Again a major change . I can now shift 1-2 as quickly as I like , the grind is gone , all the syncros were rebuilt as well and I am very happy with the results. 3.the end result is a much more enjoyable car to drive on the street and I'm looking forward to getting it back on track this weekend !

George, what 1 part had the biggest affect on lowering oil temperatures? Or was it the tune. Did the Zion radiator really make much difference? I have found that stock M radiators are efficient for race use. What are your findings for FI?

So I have been reading through several posts on here, as well as other sites, and I am interested in doing a similar build. I had a couple questions regarding your setup. First off, I will start by saying that I am by no means a mechanic so my technical knowledge isn't quite as high as some others in here.
I currently have about 75k on mine and I need to repair/replace a few things too. I have read all your posts regarding the clutch/flywheel combo and figured I would stray from the lightweight flywheel too. However, currently I am getting some really bad jerking, usually while in reverse. After talking to a local mechanic who worked for BMW for 20 years, he seemed to think my DMF could be bad. He said the springs that hold the tension and keep it from going in the wrong direction can go bad and actually allow the wheel to twist the wrong direction, then spring back and forth causing a perpetual jerking motion until I push in the clutch and let it stabilize and reengage it. I was curious if there are any upgraded DMF options to go with the clutch you recommended? Also, I was curious how much the tranny polish and rebuilt was, if you don't want to share openly would you mind PMing me. I ask because I stumbled across the Samsonas gear box on VAC for $7500 and was curious how it would be in comparison to your rebuild. For my build, I am planning on the usual SS v2 headers and sport cats and the VF-570. I was also looking into the VAC stroker kit. I found one forum where A guy talked about doing it, but never posted results! I'm curious how the pistons and rods in the stroker kit would compare to the lighter weight aftermarket setup you ended up with or if the stroker kit is even a viable approach as part of the engine rebuild. Perhaps it would be money better spent to just upgrade the internals alone? Also has anyone ever confirmed that the 288 cams will NOT work with the SC? I stumbled across these that say "for supercharged, and they appear to just be the same as factory 280. Is there any difference what so ever in these vs stock cams? I was already planning on doing all new lifters and such too. I was also considering cylinder sleeves and perhaps the stage 3 head setup, but wasn't sure if it was really necessary or if I could get away with just upgrading the springs and what not. I don't want to waste money, but at the same time I want to build the engine so it is fully capable of handling the abuse. I fully intend to track the car regularly but want it to still be streetable. Again, I am not as technically knowledged as others may be, but I am trying to learn as much as I can, so if I said something that is dumb or doesn't make sense I would appreciate tutoring rather than ridicule. Thanks, Brian |

Thank's for the timely response and the advice. My plan is to track the car. That's very unfortunate about the tuning issues with VF, is ESS having any better luck with the extensive tunes like FI with stroker and/or increased psi with cylinder sleeves? My goal was some where around 550-600whp and an engine that can maintain consistently higher rpms. I saw some videos where HPF built a 1000hp daily driver s54! How is it that he E46 is capable but ours cant?!
