I just cant understand why someone would go from a TTV8 after spending $22k on it to a powerdyne spec supercharged 6 and say how much better it is than its turbo equivalant.
Surely you have your reasons for doing this, if you explained your situation and why you changed then surely other people might understand what you are on about. |

How much are you guys getting paid?

No one is trying to force Raptor products on people they are only excited about there new found power adder thats all.
I tryed to realisticly price every thing for a single turbo v8(for my ebxr8) and i simply couldnt see it being less than 6 grand, unless i could weld but i cant so no savings there. The centri supercharger maybe a compromise but it doesnt change the fact that they work and work well they do, obviously badcooky loves his damn POWERDYNE ( read Raptor but as dan states ). Im trying to understand why there is bad blood between these differing types of power adders, each and every single type works. Some people preffer there setup over (substitute for your fav power adder here) for there own reasons, if setup correctly it will/should be a weapon. No doubt that a well setup turbo application should produce better times but why compare a ba ute with a raptor to a fmi turbo xr6 ?, i have never seen nor heard of a T to have over 190rwkw STOCK. Please noone try to take this the wrong way but understand we choose what we choose for our own reasons. Peace Brad |

How much are you guys getting paid? I'm not defending rapture, in fact I haven't said anything defamatory nor defending any particular product. more neutral on the subject sort of speak. as I recall, the subject was about PD. But you lot prefer to pay more attention to a newby with a big mouth who appears to be doing a good job baiting you lot. 
Just ignore him for now until he has solid proof {dyno printout} As for getting paid? I'm getting the full raptor kit send down as a gift/incentive to organise a group buy. ROFL I think you should all read raptor_xr8 post, maybe some of you will snap out of it & get back on topic. LOL

You can "aircool" them, you can run tricky belts, whatever. It still happens. And I think it's wrong to push them without highlighting that. I'm pretty sure Tim Staier is well aware of this fact, as one of the other things he does is repair & upgrade Powerdynes with better belts, bearings & impellor. IIRC he exports his bearings to the USA. So he knows a thing or two about the potential shortcomings of centrifugal SC's. I could well be wrong, but I doubt that the design criteria for "the first all-new centrifugal supercharger designed from a fresh sheet of paper in more than 20 years" (according to http://www.928m.com/parts/raptorsuperchargers.php) would include the Powerdyne's out-of-the-box levels of quality and reliability as a benchmark.

Also Raptor clearly state that the blower will boost to 14psi BUT no warranty after 10.
Up to 10psi (warranted operation) and up to 14psi (no warranty if used over 10 psi) See for yourself. http://www.raptorsc.com.au/products.php What i would like to see is people getting behind an Australian product, also ask youself why has capa now lowered there prices for there sealed head units? Another thing to consider is belt slip which the capa brackets do seem to get a fair bit of I personally cannot vouch for Raptor brackets etc as i have made my own system. Look i think this has all gone off topic for far too long i will no longer contribute to off topic post's after this post No harm ment Brad |

That's what I was inclined to assume until I found this info --> http://www.928m.com/parts/raptorsuperchargers.php about a test installation on a Ferrari in the USA. I don't know whether it'll do anything like that on an I6, but the 2000rpm mark is significant to me. That's the stall speed of my converter. That's why I'm taking the time and trouble to run some objective tests for myself, no-one else can truly say how much effect it has on launch times and back it up with figures. When my numbers are in, I'll post them up, good, bad or indifferent. And if anyone misconstrues that as "pushing" the product, they can go f**k themselves.

Theres nothing wrong with raptor. just some punks trying to slander whats Australian made & owned. they should be supporting it. who knows, maybe in a few years they'll become the most sort after go fast bits world wide plus a more efficient model to keep up with todays fussy demands. it'll happen anyway regardless of scepticism because there are people out there who prefer a package thats easy to fit & forget. that brings us to the next objective, those who are greedy for boost, go for the "R" Tim has said he'll look into it for the 6's. centri blowers will become more efficient & reliable as technology progress. all you need is to package it & target the right market
its not going to help the situation if the cookie monster keeps coming on here stiring s**t
Who knows. in due time, raptor could become sponsors! has anyone thought of that? sly, go f**k yourself. LOL

"When fitted with a 2.5" pulley, our test Raptor produced 2 psi of boost at only 2000 rpm on a test Ferrari installation fitted with a 6.5" crankshaft pulley. At only 4500 rpm, the Raptor was already producing 6 psi! (Results vary depending on the engine the supercharger is mounted to). " this is obviously pushed to the limit of the design. They have selected a specific engine and a specific crank pulley to pull the best figures available. Still it sets a benchmark as to how far it CAN go. I highly doubt a 4lt i6 would achieve the same results, as experience shows with those who have them fitted, the powerdynes usually dont have significant gains until 3000 rpm give or take a few hundered rpm. which depending on your aplication may be entirely what you want! Horses for courses yet again... enough on the centri supers now... does anyone have a price handy on the PD setups? and ideas on where you could get brackets made? How hard would it be for an engineering joint to machine a CMC aluminium adaptor for say a whipple? These are just a few of the questions needed to be answered when considering a PD supercharger.

For short stroke engines as the Ferrari, of course they'll produce boost earlier.
CNC? kostecki comes to mind but I think they'll use their reputation as cost leverage I reckon. the only place I could think of is your local engineering firm. most of them would be happy to take on the challenge. after all, its engineering! got some ideas on sliding rails which can be use to align the s/c pulley square with the crank.................

They dont call them Kostastacki for nothing! They wouldnt touch it unless it was Cylinder heads anyway.
Obviously Boost would depend on the RPM the motor can produce to find its limitations. On a 4ltr I6 with a rev limit of 5500rpm you can calculate it out so you get Maximum boost (safe) at maximum rpm( again limiter). On my setup I get around 2psi boost at 2100 rpm and 8.7 psi at 5200 rpm. Thats on a dyno with a Manifold Pressure Gauge hooked up. Within Vortechs safe Limits I can step up to 15 psi, but that would be asking for trouble and belt slippage without a cogged belt. Regardless if the motor is a Ferarri or Datsun, the Rpm of the motor with the gearing of the crank pulley and blower drive will determine the boost. If I didnt have a couple of cars Im working on I reckon I'd have a crack. Id be using the XF manifold as it would be a good starting point as distribution would be better than working with a BBM manifold. Id be alos mounting the whole lot up and getting pretty close with the original pulley before I'd go with sliding rails for the PD. Id get the blower pulley machined to suit as well. If it were Carby I'd sit the carb on top of the blower with an adapter plate, EFI is easier though for tuning.
