ECOTEC V6 kits VS - VY

Drift it

Raptor has access to 4 dyno shops in Mackay, absolutely no problem at all even a 4WD dyno if needed..

I can minus out the parts which you already have, no problem at all. Will work out a rough price and PM it to you.

If you drive to Mackay and are prepared to hang around for the day I will fit it for you for a small sum.

well im not intending on supercharging for a while, as the engine and trans have around 235k on them! which i am guessing is a bit flogged out to be supercharging! and will probably need a rebuild! also im still getting my exhaust made up and saving for a few other mods... (am apprentice mech.) so installing the kit myself will be no worries at all.

thanks for the quick replies!

Mate, ive had the Raptor blower on my car for over a year now, and have 239000km on the clock at the moment and its still going strong. Motor hasnt missed a beat, and although I do have to pick up my car today cos the auto went bust, it was only from regular wear anyway. Just trick up the auto with a stage 2 shift kit (B&M or Transgo seem to be the way to go) and Billet Servo and you'll be fine.

Stage 1.5: NO ENGINE WORK NEEDED OR RECOMMENDED, same as above but including Front Mount Air To Air intercooler 450x300x76mm. 200RWKW+ (depending on condition of car). Manifold boost pressure will fall by 1 - 1.5 psi. Low - Mid 13 second quatermile potential VS and again a bit slower for VT on

hey can u please pm me the price for this? too many pages to look thru to see if posted or not
is it really easy to put on myself?
will be for a vs
cheers

As of yesterday Raptor has committed to design and manufacture of a 20psi system for ECOTEC's, this will be a compound system with 2 stage intercooling and/or VLC options.

Obviously only those with a higher budget will try this or those with a pre existing Raptor system, adding it to an existing system will be approx another $3000.

Strictly for very strongly built engines and definitely still a straight bolt on option, this system has potential to outperform every SC option currently on offer for the ECOTEC.

We do expect these will be very rare and the setup is going onto a stock engine (to set it up) and the superchargers will be geared back to 12psi for the pair.

More to come in a month or two.

is this an upgrade for the raptor v charger or is a completely different supercharger, and how much power on average would the ecotec put out if was running 20psi with a 4.2l stroker kit with a billit steel crankshaft in it to handle the 20 psi

[Raptorsc]

A compound system involves DUAL superchargers, ie 2 x Raptor V with staged intercooling.

As for power output, I will take a pure guess for you. I will run in through my trusty simulator .............. hang on a moment


I dunno if I believe it but its saying around 480 - 500kw at the motor for a 4.2 at 6400rpm@21psi. Torque around 850Nm


As for cost, it will probably end up similar to the turbo kits of around the same power, say $9000 +

[nermal]

whoa! that is an extream amount of power out of a v6, and where would the second supercharger go would replace the power steering pump, i cant imagine what it would look like, the ecotec's look strange enough with one supercharger on the side instead of two

cheers

well i cant afford billet servo so i bought a corvette servo, and i couldnt afford transgo so i bought B&M stage 2!...however i checked my oil dipstick and there are metal fragments in the oil!!! so i'm not sure how much longer it has left but its getting a service kit/corvette servo and a shift kit whether it likes it or not!!!

My apologies mate, i thought i typed billet/corvette servo as i have a corvette servo in mine. I guess i didnt reading it back though...

Sounds as though you have the same as mine then, B&M Stage 2 Shift Kit and Corvette Servo and like i said mine handles the power fine. Last dyno was 246hp at the wheels, should be about 255-260ish hp at the wheels now hopefully...

Metal in the oil isnt a good thing though dude... might as well trick it up seeing as your gonna have it out anyway huh?

Mate, have a flick back to page 12 of this thread and check post 285 and you'll have an idea of what a Twin Raptor Supercharged Ecotec would look like...

Its in a Red VS Ute with a VX Clubby front bar on it...

what sort of mods could i be doing if i pulled out and rebuilt the auto as i havent had much to do with them!! only pulled them out! thats it! lol
would there be performance bands and clutch packs???

how does the corvette/b&m combo go!! obviously harder in your blown beast then my N/A would go! lol

something like this maybe: http://cgi.ebay.com/ebaymotors/High-...Q5fAccessories

Mods: Shift Kit, Servo's, Performance Bands, Clutch Packs, Fully Manualise the Valve Body, & Shifter. Im sure there would be more but thats all i can think of at the moment...

Im very happy with the B&M Shift Kit and Corvette Servo upgrade. Definately made an improvement in the shifts in N/A form. Definately shifts hard with the blower on too, but the blower was done after the tranny so i dont have any comparison for you on the difference pre-post blower sorry. I can however say it easily chirps 1st to 2nd and 2nd to third as it is...

Something like that i think yeah, but have a search through the forums for as much intell as you can first. Im not too sure about ebay for some things though, and trans stuff is on that list for me. thats obviously my own opinion, but just be careful...

ok cool thanks im only new to this site and have not yet gone through all the pages so im a bit behind

For sure it is there as quoted and I guess from the front it won't look a lot different to that, the images I am going to post up in a couple of days time show in a basic fashion how it all hangs on the motor. The install of the chargers themselves will be quite basic, the intercooler systems will be more involved

Hi RAPTR6, I e-mailed you 2 days ago and still don't have a reply, so I'll posting here. Where are the dealerships in Australia, How do I contact them?

If I install FIT 1.9 : 1 rockers do I have to perform any other engines mods?

I own a 2000 VS Ute(manual) that I would like to supercharge. The motor has done 150 000km and is stock. However, I have fitted pacemaker extractors and 2.5 inch exhaust.

Do the kits come with everything I need to complete the job? If not what else is required?
Cheers

DJAA : half way down page 19 there ar stage 1 and 1.5 prices posted by raptor

[djaa]

Cheers, I found that after the post. Still can't find where to buy them from or how to contact them though. (New to forums, so I'll keep looking. Any help would be good though)

[djaa]

Cheers mate, Found it after I made the post
I am a newbie to forums, but I am learning a lot quickly.

Mate sorry I missed responding earlier, if you have any specific questions let me know and I will sort them for you

This afternoon we had a bit of a comparison between a customer with VT and my VY

Both are intercooled, both run the same blower pulleys but the results over a set distance are quite different

The VT makes 13psi and sometimes 14psi on the gear change has standard rockers and reverse plenum. VT dynod recently at 208rwkw, tune is non intercooled tune. The VT runs a 450 x 300 x 76mm intercooler core

The VY makes 11psi and never more and has 1.97 FIT rockers. Not dyno'd recently and runs the Raptor stage 1.5 generic chiptorque tune. Raptor VY has a small 280 x 300 x 76 intercooler core as is sold with all the Raptor intercooled kits unless customers ask for a bigger item.

Exhaust systems on both are pretty much identical, the VT is probably a touch better.

First thing is why the pressure difference, well the VT has the 4.0" intake and a huge filter, this simply feeds the supercharger much better, this is confirmed by the removal of my airfilter on the dyno showing a 6rwkw gain. This brings up the pressure another 1 - 2 psi.

Out on the road the VY was clearly more powerful and the only things we could put that down was the high lift rockers and the tune. The VY was around 8kmh faster over approx 400meters, which is a few MPH for sure.

Intercooler size seems to have no real influence on the power, just so long as there is an intercooler of some sort and the intercooler in this case has no influence on system pressure. The reverse side plenum probably helps too as pipework is shorter, always a good move.

So now the quest should be to fit the VY with 4" intake and see what we get, also the VT is copping a set of 1.98:1 MACE rockers and I am interested to see if there is any drop in boost pressure due to additional air flow. Of course we will be looking to see if the mid range is getting stronger on the VT (after rockers) to match the VY which feels very torquey.

I did play with a bit of blue printing on my VY charger which made the bottom end response sharper than it had been.

[drift-it]

the vt is a bit heavier then the vy isnt it??? i know there heavier then the vs! what sort of torque are ya getting from your vy?

[Raptorsc]

Drift-it

I believe the VT - VT all much the same weight, the VT was the first of the wider body type after the VS and continued on to VZ.

I will give you a torque figure again soon when I give the rollers a spin. Used to be around 475Nm on the engine at 9psi, should be nicely into the 500's now

[djaa]

No worries. Got everything answered except. If I install 1.97 : 1 roller rockers do I have to change springs, push rods or anything else? This will also be installed with the raptor V series intercooled supercharger.

I also read on a thread a couple of people installing a second bypass or a BOV. Is this neccesary with your kits or have they just set them up incorrectly?

Cheers

[Raptorsc]

djaa

I am not sure which brand of rockers you want to use but normally there is no need to change springs, push rods or otherwise. I certainly never have anyway and nor have most other people.

The second valve is always necessary, system users/home manufacturers are advised to have a second valve if they have overlooked the fitting of it. It is necessary.
