  1. Hey Zentex, So, I might be able to help. What you are looking for may have nothing to do with being US spec or not. It might have more to do with the version of the interior that you have. Try searching for the 2006 G35 coupe interior instead. Personally, I have a 2004 G35 (left hand drive) and have owned it since that time, so I know of the clock surround you speak of since I have that particular one. Hopefully, this will help.
  2. Hi Dr. Factory, just curious about your power numbers...is this bhp or rwhp? The reason I ask is that I am used to the rwhp as this is what is used in the US. Here in the UK they use bhp most of the time. If 360 is rwhp, then your bhp is certainly higher. This may help your claim with your hp numbers and might help with you ad as well.
  3. Bullen, that is one thing I like about the twin turbo set-up, is more torque down low. I always thought with these cars that you had to stay away from twin turbos if the engine was stock. Seems like Jez has sorted it safely. Must be nice to drive. Zmanalex, if you have been running turbos on you Z since 2009 then I wonder why reputable garages were giving me different information. Here is the kicker, I have a left hand drive G35 so the whole issue with the supposed issues and turbos on right hand driver vehicles has no argument in my situation. Dynosty is one of the top US shops for the 350z and G35 and they are churning out 600hp twin turbo built Zs and Gs as standard. I'm just a bit disappointed that I could have had more with my car being that its been built and had much more potential.
  4. Hey guys, Just wondering if anyone has any experience with the new HKS supercharger kit? I thought I saw something a short while back by Abbeymotorsport. Seems like this kit has more potential than a Vortech, especially with a built engine. Here is the link: http://www.hksusa.com/12001-an008-gt-s-c-system-pro-z33-vq35de-ver-2/
  5. Thanks again for the added information. GM, thanks for the links. I remember the thread for years ago way before I did my build and supercharger and it was quite helpful at that time. Futhermore, I think I wasn't that specific in my last post as I was addressing the root cause of why someone would want to upgrade pulleys for a supercharged system. I'm already running the upgraded 3.12 pulley from the standard 3.33. I would have gone with the 2.87 but I'm already pushing past the max impeller speed with the current set-up. My engine is built with Cosworth pistons, Eagle rods, and supertech valves and I'm also running the larger Fluidamper crank pulley which is 6.125 I believe over the stock 5.75. This was recommended by the builder when my crank was balanced. Because of this upgrade I'm also pushing close to the same impeller speeds as one one get running the 2.87 pulley with a standard sized crank pulley. Additionally, I was able to push the engine up to 7100 rpms on VQ35DE non-rev up engine since the internals are forged. Abbey did not do the build but they did do the initial mapping on the dyno and mapping after the engine was broken in. Since it was being supercharged, I was going to stick with a 10:3 compression ration like stock, but instead Mark at Abbey suggested going with 10:1. Needless to say, I made 423hp on Marks dyno at the hubs which he said is around 455bhp. Later I went to Horsham and had a remap and made 452bhp. I have owned this car since 2004 and been running on a built engine with supercharger since the fall of 2013. All the other things that most people do I have already done as well to include a CJM Stage 1 Fuel system, Injector Dynamics injectors, oil cooler (although I found it unnecessary), and the list goes on. Can't remember everything since it was 3 years ago now but I have several upgrades in my build internally and in supporting mods. The reason I posted this message is because it seems that most people are making power in the same power range, so regardless of having a built engine or not I'm not really making any more power than anyone else, I just have an engine that can handle those numbers safely. If all the supporting mods are there and if the engine can handle it, then the limitation to me is the supercharger itself. I could be wrong, so please chime in if you have another opinion. On the Vortech website there is a part on there where you can put in information to determine the impeller speed based on the vortech unit being used, the crank pulley size, and the supercharger pulley. It seems that page is not there anymore since Vortech changed their site and another site I used seems to be giving me different numbers. With a Turbo I could just turn the boost up, but on the supercharger we have to upgrade the supercharger pulley. I just wish I was advised about the other trims before I bought my V3 Sci. I knew I didn't want the T-trim, mainly due to being loud but the Si looked more promising. I believe a shop called 928 motorsports does upgrades for superchargers, but not sure if anyone here has used them or even bothered trying to upgrade the supercharger. Jumping350, it would be nice to make over 500 to be honest. But, really, I'd rather have useable power instead of a high peak hp. I'm not too concerned with belt slip as I have the GTM pulley mod and the Timrod radius bar kit for the supercharger bracket.
  6. Hi ZManalex, these were my thoughts exactly. Before I had my engine built I was really leaning toward a turbo, but since I was having the mapping done at Abbey, I wanted to go with what the tuner would suggest as that is what the tuner would feel comfortable with. I was convinced that a supercharger would be a better route. The US shops that it didn't make sense to have a built engine with a supercharger, but that is what Abbey suggested. In fact, the suggestion was to buy the GTM kit over the Vortech since the Vortech was more agricultural. At that time, I couldn't understand how a shop would have no problem mapping Skylines and GTRs with over 1000hp run on turbos and suggest I run a supercharger over a turbo set-up. This would come a bit more clear as to why later though, but at that time (late 2012-summer 2013) I went with the suggestion of the tuner. Also, I can't remember if SYVECS was around at the time, but I'm running Uprev installed by Abbey. I ended up going with the Vortech, which I'm glad I did since GTM does not exist, and pushed a bit more than standard numbers on a built engine. Since that time, I've had my engine remapped at Horsham and have been going there ever since. I had an alignment done this past summer and brought up the whole supercharger turbo dilemma as I was wondering if could still go the turbo route with a built engine running a 10:1 compression ratio. Jez explained that at that time, the only turbo kits available for this car was for US models therefore, a lot of people did not have experience mapping turbos on these cars as that time as the turbo kits did not fit the UK spec zed straight out of the box.. After I heard that, it made sense as to why I was swayed toward a supercharger back in 2013. Again, not to take away from the original post, Bullen I'm assuming your compression ratio is standard 10:3:1 and if you are running a twin turbo set-up, what turbo kit do you have and what type of torque/hp numbers are you making and peaking at which rpm range?
  7. Thanks for the information. Ebized, I've already ready through the link posted a while back and did my oil catch can set-up with Bennett's info on positive crankcase ventilation. Thank for the refresher on the link though. GMBallistic, I see what you are saying about upgrading the pulleys but I think that the reason for this is to affect impeller speed in the end thus creating more air flow and more power. The only change I've made regarding a pulley was the crank pulley and that is because I have a built engine and when building it I used a Fluidamper over the OEM one. Regarding a tooth pulley, which pulley are you referring to specifically? I'm still convinced, but I could be wrong, that all these mods are to get the Vortech to spin faster or to spin faster sooner, thus affecting more power to come in sooner. Regardless, there is a max impeller speed and when this is reached I'm sure there is a threshold for over spinning the blower which is why I'm concerned. I don't see a stock engine running into this issue so much with standard pulleys and what not as I'm sure Horsham and Abbey know the limits of the engines with the Vortech on a stock motor. With a built engine, the capabilities are much higher, but if the blower is impeller speed limited, those capabilities would not be attainable.
  8. Hello, With an NA engine this is probably not ideal, but with a built engine, the supercharger seems limited due to impeller speed of the unit. Just curious if anyone has had their supercharger rebuilt to spin faster? If so, was here a noticeable gain and was it cost effective? Thank you.
  9. Hello, just wondering if you are completely set on running a turbo? The reason I ask is because I went through the process a few years ago an ended up with a supercharger and a forged engine. I was really set on getting a turbo, but at that time here in the UK, a very well known garage that alot of forum members use suggested going the supercharged route. Most US shops were confused when I was buying parts from them I told them I was going to use a supercharger instead of a turbo on a built engine as you can get more power out of a turbo set-up. The reason is that even if I had the engine built and a turbo installed, I needed somebody to map the engine. If the garage doesn't feel comfortable mapping these cars with a turbo, I would be out of luck, so I opted for the supercharged route. Fast forward to today and maybe garages here in the UK are more comfortable mapping these cars with turbos now. Not sure.
  10. Hey Connor, I too was running a Motordyne TDX 2 with ART pipes. I put the ART pipes on after I had my engine built and Vortech installed. Since I don't have a comparison besides stock I couldn't really tell if it was too loud or not. In a way, I just got used to it...until....I went to Germany. I spent alot of time on the German Autobahns when I was working there push the 150+ mph range on a daily basis. After going back with a built engine, vortech, and full MD exhaust, the experience wasn't as pleasant. Exhaust was extremely loud, that even people at rest stops were looking at me flying down the autobahn. With a modded vehicle was afraid to keep it above 140mph to be honest. Anyway, that is another post it itself. Agreeing with Connor, the MD exhaust has a very unique sound a bit like an exotic. Cruising speeds are pleasant and droning is cancelled out. Above 3500 it becomes a monster though. Without a supercharger, I was probably pushing the limits on the loudness of the exhaust anyway.
  11. Whitevanman, Good to hear you are enjoying your new car. Definately a good choice, but I would like to see it in person at some point, hopefully soon. Tarmac, How well does the Milltek system work with the Motordyne Y-pipe with resonator or HFC extension and ART de-cat pipes? Does that set-up drone or sound raspy at all? How loud is it compared to stock or a full blown Motordyne set-up? Thanks for your help.
  12. Hey Jetpilot, thanks for the tip, I'll try to find the video. Whitevanman, nice to see you here. Are you happy with your 370? Are you running the Fuji on your new car or was it on the other one? Is there a certain RPM range that the volume increased? I may post another thread about this, but is drone inevitable for every aftermarket exhaust in the 2200-2900 range? The Motordyne TDX2 was pretty good in this department actually. Wasn't really any drone at all at this cruising range speed. Above 3500, everything changed though.
  13. Thanks for the input so far. I'm was actually running the MD TDX2 for a while. I can't complain about the exhaust itself as I didn't notice much drone at all but it is very aggressive (in a good way) above 3500 rpms. I might be selling it soon, but since I'm still using the Y pipe part, I'm looking to get a new MD Y pipe so I can sell the set complete. Anyway, I've heard the Milltek is good, but I have not heard it in person. How does it compare to a Tanabe Medallion or a Fujitsubo? I've heard those two are toward the quieter end of things. Also, and this may be a rumor, but I also heard something about the Milltek quality decreasing recently for some reason. Were they made in a different factory before or is that just false rumors? Thanks for all the help.
  14. I use mine as a daily driver and I'm using Mobil 1 0W-40. I remember coming across a thread on the US 350 forum and there was data collected on various types of oil samples and Mobil 0W-40 seemed to have decent results. I want to say the Castrol 0W-30 green bottle made in Germany yielded the best results. Additionally, this was for standard N/A engines. The Mobil 1 is fairly easy for me to get and priced decently as I'm over 230K miles now with a oil consuming engine so I need it regularly.
  15. I thought the V3 was actually pretty reasonable sound wise. I feel it's more the exhaust that is loud. Actually, I'm running my V3 with a Vortech filter at the end of the piping so it may be quieter because of that. Since I've been running it from the beginning it seems standard to me, but from other threads I've read, it is not standard as it does not come with the kit. I wish I knew the part number, but it's a small filter that is attached where the air is released when not in boost.
