Well guys and girls, the time has just about come! I have been doing some research on some serious performance/power upgrades. I am within an inch of supercharging the V6. The kit i am looking at is the Raptor Pro Street centrifugal supercharger. I have read some decent reviews about the kit, and have seen some pretty impressive results achieved with this kit. The kit will bring the car to around the 200rwkw ball park. Anyone familiar with this kit, and if so, what do you think?

They're good.
But I don't think you'll be seeing 200rwkw. Maybe 185, at most. |

| The bottom end will require work, which makes a cam more appealing to me now. |

if you do your cams you will get an extra 40kw from stage 3 crow cams and you already have the 1.8 yella terra roller rockers, if you supercharge on top of that you will be unbeatable.
but yeah it's pretty easy to spend someone else's money lol. |

| I was speaking with my mechanic last night about the supercharger. He was saying that the motor would withstand 8-9 psi boost without requiring the work to the bottom end. So much food for thought! |

yeah u don't need anything massive like 16psi for srteet use but you wanna take it to the tracks don't you?
my brothers mate is turbocharging a non-genuine VL (stupid choice) which is okay the most it will handle is another 6-7psi but i just know if he as a boost controller he will wind it up and blow everything to pieces but it's his choice.
the Buick 3800 is a better motor and a supercharger will do nicely.
have you spoken to vnsvle? |

| My mechanic said the same thing crazybiker. He said that if i keep it under 10psi, i wont have any problems. The occasional run at the track would be fun, nothing crazy though. $4600 for the supercharger kit versus $3700 for the cam package, what do you boys think? |

| I like the sound of a big lumpy cam! I had a conversation with the guy i got the quote for the cam, and he said after a live dyno tune and the cam upgrade that i would be looking at around an extra 30rwkw. Thats not just the cam, but a combination of the cam and the tune that will bring this power increase at the rear wheels. |

I did read your post crazybiker. Thanks buddy! The problem with the cam is the drive-ability, due to the lack of low down torque with the power coming on in higher rev ranges. How will the drivetrain cope with the supercharger? I have a stage 2 B&M shift kit fitted to my TH700, which Raptor recommended a stage 1 change at the least. Is the TH700 the same box that was fitted to the VS and VT V6's that were supercharged? |

crazy biker is right in the performance side of things cos the supercharger will increase everything alot evenly.
the supercharger is making more power off what the motor normal does in it's cycle. so the motor is force feeding itself without knowing if that makes sense. |

I'm really not sure how the drivetrain would cope. Sorry. |

here's another thing to consider (or make more complicated) if you spend the Money you have ATM on cams it will leave room to for a supercharger on top of that. easier now then later on if you want the cams done at all.
just adding that to make sure you make the best choice for u not others. |

Standard engine with low boost the drive train will be fine especially considering the kilometer's on the car. The supercharged ecotec's all ecotec's for that matter ran the 4L60-E which is the same box as the vn's only electronically controlled.
Bit of useless information the VR commodore ran the Buick motor with the 4L60-E transmission |
What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

Low boost would be under 10psi wouldnt it VNSVLE? Thanks for your reply to my email on the weekend too buddy! I have said it before, and i will say it again, i really appreciate all you guys and your feedback. Not useless info either, as it answered my question dude.
And thanks for your advice in your last post leebo. Kind words that are appreciated. |

| I would be saying more around the 6 psi. I believe that the supercharged ecotecs run about 4 psi and i am not sure what internal differences they have over the N/A engine. |

| Thanks VNSVLE! I have read a bit more about the Raptor, and the tune has its problems, which is provided on a memcal from Raptor. The motor will repeatedly hit the rev limiter before the box will change gears (automatic). A few things have helped make my decision, and i know it has taken time, and i am thankful for this websites members and the forums on street commodores for helping me make an informed decision. I am laying a deposit down for a cam package tomorrow! |

By no means let me turn you off superchargers or cam packages for that matter. Both options if done right will reap a decent reward but only if done properly.
Chip and cam packages aren't to bad but you will get the most out of your cam with a proper dyno tune instead of the included chip tune.
Are you planning on any further engine mods??

| 6psi is as far as you would want to go with out getting a full rebuild ,, things tend to go bang at 10psi with out spending some decent coin.. |

Im getting a custom ground cam, valve springs, lifters, retainers, microtech ecu with all the necessary sensors, and a dyno tune. All of this work is being done at the same time, in a proper performance workshop. Paying the decent coin to get quality work done and strong results.
The street commodores forums are littered with stock motors that have been charged, and eventually something goes pop! |

| these engines will take 16-20psi of boost no problems stock .after that the head gaskets blow into the valley,good MLS gaskets and some good headstuds is all you really need.no need to upgrade the ecu the stock ecu is more than capable of handling upto 30psi of boost and is much better to drive on the street than aftermarket ecu's and doesnt require lots of tuning to get drivable.I myself would go turbo like T3/T4 and intercooler flag the cam or get a proper turbo cam as the hot lumpy NA cams will loose boost out the exhaust valves killing power output.check out clinto1's vn wagon here in members rides www.delcohacking.net he runs 16psi all day every day in his daily driver does 200km a day to and from work and hes running a $57 dollar ebay engine.goes extremely hard.the reason most die is way to much timing nothing to do with the engine not liking boost. |

| I have done the cam, but the supercharger is still part of my future plans. I won't be running over 8psi though. In saying this am interested in knowing more about the T3/T4 set up though delcowizzid, and i would greatly appreciate your input champion |

| most things are in that thread its a nice simple way of doing it only requires the one passenger manifold to be made and a crossover pipe from the driverside stock manifold to be made |
