PZR Posted August 13, 2006 Share Posted August 13, 2006 I'm sure this has been asked before, But I had a look and couldn't see anything. So here goes, I'm having a hard time finding superchargers online, in the UK. So far all I can find is http://www.tdi-plc.com/350Z.html Which isn't really what I was after. I won't be buying it for sometime, so it's not really urgent. But it'd be nice to see what I can get my hands on in the UK. Quote Link to comment Share on other sites More sharing options...
M13KYF Posted August 13, 2006 Share Posted August 13, 2006 You can get Forum Discount though with TDI. See forum discounts for more info. Presience probably be able to give you the best advice on superchargers. Think he got his at Abbey but 100% on that. Quote Link to comment Share on other sites More sharing options...
Guest prescience Posted August 13, 2006 Share Posted August 13, 2006 Mike, Nice of you to mention me in this but really this is a difficult one. PZR I think you really need to think this through and identify what it is you are after and when - then I am sure with more details, help will be available Quote Link to comment Share on other sites More sharing options...
Removed Posted August 14, 2006 Share Posted August 14, 2006 true as there's a few different superchargers on the market Quote Link to comment Share on other sites More sharing options...
PZR Posted August 14, 2006 Author Share Posted August 14, 2006 I'm after a twin-screw supercharger really, but so far I've only found one, which isn't suitable. I want to take the engine up to 380 to 410BHP, I don't really want to go over 410BHP for the sake of the engine, and the fact it'll need more internal mods if I go to much over 410. But all I seem to be finding is the HKS centrifugal kit. Like I said, it's not urgent, it's more research for the moment, of who supplies them, and where, for how much. I've got some other mods lined in mind first before I get to a supercharger, but I thought I might aswell look for them early Quote Link to comment Share on other sites More sharing options...
Guest prescience Posted August 14, 2006 Share Posted August 14, 2006 Thee are no twin-screw superchargers available for the Z (to the best of my knowledge) You are resticted to Centrifugal: HKS, Vortech, ATi Roots: Stillen The Vortech is the most tuneable and is one of the cheapest. This has been used fairly widely on Euro cars The ATi has suffered more engine failures than the others since it does not incorporate timing adjustment as part of the kit - you need to add it; this has rarely been used on Euro cars The HKS is perhaps the best manufactured but is expensive and less tuneable than say Vortech. This has been used fairly widely on Euro cars The Stillen is available in about 4 stages (Stage 4 requires a built motor and Stage 1 has no intercooler for example) but is completely non-tuneable but does benefit from a engine warranty. This has been used only infrequently on Euro cars All of the above (except the Stage 1 and 2 Stillen) should achieve the power levels you wish for Quote Link to comment Share on other sites More sharing options...
Guest prescience Posted August 14, 2006 Share Posted August 14, 2006 In terms of supply. Vortech is best imported from the US HKS is available from at least TDI PLC (a member on this board), Abbey Motorsport and Middlehurst (St Helens) Stillen is available from Mr.F a trader on this board ATi would be best imported You can reasearch all of these on any of the following US Forced Induction forums http://www.my350z.com/forum/forumdisplay.php?f=182 and http://www.350zmotoring.com/forums/foru ... rune=&f=44 and http://www.350z-tech.com/forums/index.p ... owforum=80 Quote Link to comment Share on other sites More sharing options...
PZR Posted August 14, 2006 Author Share Posted August 14, 2006 From what I gather, you need to use a modified bonnet to fit the Stillen supercharger in the engine bay? Which I think looks awful, unless of course I can find a bonnet that suits it, in which case I'd go the Stillen route. But it's the boost throughout the RPM range that I want really, which a centrifugal can't seem to deliver, and is essentially just a belt driven turbocharger, so there would still be some amount of lag, so they seem to be the worst of the lot. Or am I wrong? Quote Link to comment Share on other sites More sharing options...

Guest prescience Posted August 14, 2006 Share Posted August 14, 2006 Its OK - perhaps I was peeved that you dised my S/C as the 'worst of the lot' LOL I think you are not quite right, there is not really lag (cf turbo lag) with a centrifugal S/C as such but it is true that the boost builds higher in the rev range. Its a bit like stock but more so, without a kick in the back as per the turbo. For the Roots style, this is certainly the most inefficient in terms of power delivery (because of how it works - wikipedia is very good for this BTW) but is does get peak boost as early as 2000 rpm. Other than the bonnet, which I'll come to, there is another disadvantage with the Stillen - it suffers more from heat soak due to where the S/C has to be placed (centrally in the engine bay); this is ameliorated somwhat by an intercooler which is essential for Stillen (and is included with all the other kits BTW), but it will be more of an issue than say with Vortech IMO. The bonnet is a problem, if you don't like it (and neither do I) nothing will persuade you. Some guys in the US have been experimenting very recently with longer hinges to raise the stock bonnet up, but this must leave a gap somewhere surely?

PZR Posted August 14, 2006 Author Share Posted August 14, 2006 Its OK - perhaps I was peeved that you dised my S/C as the 'worst of the lot' LOL Heheh, sorry I think you are not quite right, there is not really lag (cf turbo lag) with a centrifugal S/C as such but it is true that the boost builds higher in the rev range. Its a bit like stock but more so, without a kick in the back as per the turbo. Do you by any chance have a dyno reading from your Z before and after your supercharger? It would be nice to see what sort of power gains it gets lower in the rev range, since that was an appeal of a blower/twin screw type, having the boost much earlier, all the way to the top end. Other than the bonnet, which I'll come to, there is another disadvantage with the Stillen - it suffers more from heat soak due to where the S/C has to be placed (centrally in the engine bay); this is ameliorated somwhat by an intercooler which is essential for Stillen (and is included with all the other kits BTW), but it will be more of an issue than say with Vortech IMO. Yeah I noticed that on the links you gave me, it's putting more stress on the engine aswell then. The bonnet is a problem, if you don't like it (and neither do I) nothing will persuade you. Some guys in the US have been experimenting very recently with longer hinges to raise the stock bonnet up, but this must leave a gap somewhere surely? Yeah the bulge in the bonnets just looks wrong on a Z, if I could find one that suited it, I would possibly go the Stillen route. From what I gather, a blower type would be the most reliable, but would it be the most reliable in terms of the engine aswell? I want to get the most reliable system I can really.

Guest prescience Posted August 14, 2006 Share Posted August 14, 2006 No I don't have a before/after dyno. Stephen G may have though. With a large displacement motor I don't think its such an issue low down; you really would need to drive one IMO - all the charts in the world won't give you the full SP. The Vortech is a nice system and overall the best of the S/Cs in my opinion due to its cost, tuneability, ease of install/de-install etc As I say Stillen give you an engine warranty with their system, so if that is important to you, that's a big plus. Contact them and ask if they extend that warranty worldwide and what it covers etc Quote Link to comment Share on other sites More sharing options...
PZR Posted August 14, 2006 Author Share Posted August 14, 2006 Cool, thanks for the help. I'll look into the Stillen warranty then, since depending on what it covers, it might be the way to go, if I can find a decent bonnet. Quote Link to comment Share on other sites More sharing options...
Golfer Posted August 16, 2006 Share Posted August 16, 2006 Has anyone got any thoughts on the Nissan GB GT-S concept car with the Novidem supercharger. Has any one heard of this supercharger? This might come with a Nissan warrenty if it sells to approved centres. Quote Link to comment Share on other sites More sharing options...
Removed Posted August 16, 2006 Share Posted August 16, 2006 which apparently it won't Golfer PZR, I wouldn't bother with a Stillen: MrF has the stage 4 (Iirc) and still can't do faster than 13.8 at the 1/4 mile, that's about 0.5 seconds faster than my NA Z. His kit keeps overheating and heat soak is a real issue. IMO I'd go with either a Vortech or a TT kit like the APS Quote Link to comment Share on other sites More sharing options...
Guest prescience Posted August 16, 2006 Share Posted August 16, 2006 A Stage 4 is only available with a built motor - has Mike had that done Much more likely he's running Stage 2 (which is the only one with the warranty, I've checked) Quote Link to comment Share on other sites More sharing options...
Removed Posted August 16, 2006 Share Posted August 16, 2006 nono he was saying he's got all the newest bits for the latest stage! definitely extra stuff, quite sure he mentione the latest stage available (4) and no don't think he's gone internals Quote Link to comment Share on other sites More sharing options...
PZR Posted August 16, 2006 Author Share Posted August 16, 2006 Hmm, looks like stillens aren't to great after all then, and like prescience said, on their website it only mentions Stage 2 having a warranty. Shame really, since most of the reason I want a supercharger was because of the twin screw and blower power delivery over a centrifugal, I'm sure a centrifugal will still be nice though What would you say is the most reliable of the centrifugals then? I'm taking a guess at HKS? Cheers. Quote Link to comment Share on other sites More sharing options...
Baptist Posted August 17, 2006 Share Posted August 17, 2006 I thought they had stopped making the HKS supercharger. Nothing but trouble that thing, rubbish. Dont know why people bang on about HKS so much, totally over hyped, most of their stuff is rebadged gear made by other people anyway.

Removed Posted August 17, 2006 Share Posted August 17, 2006 yeah HKS TT due out this month afaik. I haven't heard issues bar from very few people in the US about the HKS SC tbh Quote Link to comment Share on other sites More sharing options...
