With my 5L the Raptor is always pushing enough air to overcome this LOSS associated with turning it, it has more push off the line but its mid range and top end are just awsome.
Any way its crap that ppl say centris are crap for street use as when you need to over take let me tell you, you will have more than enough power to get up and go. Its true that you can get away with out a proper ecu tune on the turbo but id doubt as to running anymore than 6 psi intercooled.

Thats Wes with the Eb v8 turbo from street fords dvd.
A higher stall converter will fix its slow leaving the line ness, for me it was alot easier to fab up my brackets from scratch and out source all the little bits such as fuel pump ect.
Either way the car will be quicker.

Raptor_xr8, there are people here that will argue this to death. theres no difference between holden & ford. the Holden nut will always say they're better because they can make more boost. I combare turbo's as reliable as holdens. fast for a short period of time before they f**k up.....
theres no difference between the two when it comes to parasitic lost. one looses power due to exhaust flow restriction, the other through direct drive.
I ask one question. which setup has broken the quarter mile more then the other?... ay ay!
SUPERCHARGER!!!!!!!! |

In general, centrifugal superchargers will make more power (all other conditions being equal) than a PD supercharger, with less heat generated.
I was speaking to a guy over here today who has a Raptor V on his 3.8L V6 VX Commo..
He absolutely loves it, he's making 235 rwkw.
He hasn't noticed any parasitic losses whatsoever, and his car is perfectly streetable, with boost easing in at around 3000rpm and pulling smoothly all the way to redline.
The Raptor also emits a nice whine at idle that increases with rpm.
The Raptor V chucks in about 9 psi in standard kit form, which is perfectly safe for most stock motors ...the VX dude is going for 13 psi with a pulley change and some moderate engine work.
I'm sure Brad can post a video link to his XR8, while I dig up the video of the VX. |

True, what most people don't realise is the mass lost they're referring to is the older bulky roots & twin-screw blower. the more modern belt driven turbo{centrifugal} is a free spinner. it requires less energy to drive it, making them more efficient due to their design & lighter weight.
Not to long now before you'll see centri generating boost up to 20psi or more. I also read through raptors home page that the raptor "R" is due out which is good for 17psi. that stage would see you forking out on some heavy engine internals & blueprint work, gearbox & drive line.
man, I'll be more then happy with a straight forward bolt on 9psi centri kit that would only take you 1 to 2 hours to install & flash tune, then f@rt assing around with a turbo, roots or twinscrew charger. |

| I drove home from down the coast yesterday, I had a mate in the car (actually he drove the last leg home), my dog (65kg), a wagon boot full of junk, and we were towing a boat and both he and I were impressed with the torque from the Powerdyne when we were overtaking (and his car is a BA XR6T which my wagon is not as quick as). |

Heres a little clip it was done the day after install and couldnt rev it past 3000 rpm. ( due to running the blower in)

Im going to add some more photos to my thread in the forced induction section later.

Just hooked up speakers to my PC to watch your vid RAPTOR_XR8..
That's a mighty loud whine you got going on there ...I take it the whine dies down during the 'run-in' period?
That's what the VX dude told me anyway. |

Number 3 is also a little misleading, in that the supercharger is STILL turning and robbing crank power with the throttle closed, it also makes a fair bit of heat. Bypass valves generally help in this area but the supercharger is still using power directly from the crank while your idling, cruising etc.
well an engine with a roots/lysholme supercharger will make back the power its robbing by lifting diabetic efficiency when idling. motors are generally accepted to run around 70-80% DE, but will be closer to 100% with a properly fitted and setup screw charger. Pretty much breaks even at idle and builds instantly and very very hard.
Im sure someone could fab a bracket to sit a whipple where the BBM is. Then look out you turbo boys... I hate the exhaust note of turbos, give me SC for grunt and growl. dyno figures FTL. |

| if a roots psi blower is so power robbing old fashioned or turbo technically so boring , tell me why top fuel world champion drag teams use them only!!!! |

| The power it produce outweighs the power it looses people. it does lose power but it makes more by as much as 100%. the only thing people should really fuss about is: will my engine cope? |

The reason why it was loud is because i need to clean the isc in neutral it sits at 1000 rpm, i do think its quieter since run in but you still get looks from ppl and they keep asking is that a gear drive ?.
I cannot feel a loss in power from running the charger, everyone says these centri blowers dont make any power till 3000 rpm. Well my car has so much more power off idle compared to stock its not funny, you get a fare amount of wheel spin and when she does get movin it FLYS.
I have been in my mates 180 sx and it is an animal putting out 255rwkw i wish oneday to hit that figure and his car is an animal but the manual makes it feel more animal, how my car is now i would have been able to beat his old setup... to bad he is running 20 psi/
In my opinion any type of forced induction at the same power level should produce close to the same times as each other its just that some make more power than others. |

Piece of cake!!! You wouldnt have a spare one u could lend me 'eh??...lol. Not sure how the bonnet clearance would be though, but it would sure look like sweet action!!!

I definately have not lost any down low power, but off the line the car feels no different. But then I'm only currently running 6psi, bump it up to 9 and I reckon it'll give me some more ooomph a bit lower.
However, when rolling up to a Give Way sign etc and then booting it it definately pushes me back into my seat. |

Piece of piss.
Probably easier to make a manifold up. This is Keedlez. Awesome car. |

The E-series kit is not fully developed yet ...Tim from Raptor needs about 6 weeks to confidently release it.
Things to consider are your compression ratio (the Raptor needs about 8.6, so a decomp plate and head shaving are likely to be needed if you have a big cam) ...and the size of your extractors (primary pipe needs to be 40 mm diameter minimum). |
