Raptor Superchargers Project Car VY

[Raptorsc]

We picked up a VY exec today, stock as they come with 54000 km. This car will get a gradual buildup to become an S or SS in appearance. The main aim is to get motor supercharged with Raptor Prostreet and then Intercooled Prostreet at a later date.

Will take some pics as we go, will get stock photos and start from that.

Will also attempt to get stock quartermile and dyno measurements to compare with the improved output. The parts we fit will be typical of what an owner would modify.

Will be likely fitting:

1. FIT 1.97:1 Xtreme rockers COMPLETED

2. HM headers and HSV exhaust COMPLETED

3. Raptor V ProStreet 9.5psi kit COMPLETED

4. S/SS genuine body parts to give the exec a makeover.SS WING AND GAUGE BINNACLE ADDED more to come

5.Billett servo's for auto to improve shifting

Timeframe: mostly complete by June 07


Then there is VY (and VU, VX) Prostreet intercooled

1. Fitting Cobalt Autometer real time intercooler temp gauge and boost gauge in binnacle COMPLETED

2. 75mm MAF NOT NEEDED FOR VY V6

3. 280x300x76mm intercooler and 75mm piping COMPLETED

4. Full retune to balance everything for perfect power and reliability COMPLETED


Should see some pictures attached and there is even a time slip for the STOCK VY as it came straight from ex fleet lease. Don't know if the time is representative of VY exec's generally but we are extremely pleased to see a 15.65sec 400m time. At least we got one with good standard performance

Just a Q, why the choice of FIT and HM?

[Raptorsc]

Extractors


All test results for Raptor kits have so far been developed around both Pacemaker and Genie Extractors. However prior to the Holden kit work we used only HM, we had great service from that company and the product worked well, thought we should give em a go on the V6. The HM does seem to have a bit broader powerband than most other brands and there are a few header options from them which go well with supercharging. Will be ringing them for full and complete information and will let you all know what part number we go with and how it goes.


Rockers

We have had an association with FIT for sometime, some of our customers use YT and some use FIT, again both seem to go pretty well. So since we know Tony and he been good to us in the past we will try his 1.97:1 rockers, it is possible they may not fit due to casting changes in the VY ECOTEC, he has made us aware of this, some motors have it worse than others. If they FIT (pardon the pun) we will use them, if not then maybe we will go with YT as they have a solution to the casting issue.

We don't get too pedantic about all this as customers will want variations for whatever reason anyway, we are just going for a combo which we believe will be great for the Raptor VY

Looks good mate, should make some serious power. Look foward to seeing the results.

Today the sparkplugs have been purchased and installed

For those who have never changed their own sparkplugs before

1. For ECOTEC you need a 5/8" plug socket (long reach socket) and a rachet or T handle to turn it with

2. With motor NOT running disconnect all your ignition leads from the sparkplugs

3. Using socket and drive remove each sparkplug, turn plug in anticlockwise direction to undo

4. Then unpack your new sparkplugs and insert, when tightening them do not use all your strength, just firm is good and all that is needed.

5. Reconnect all your ignition wires making sure the correct wire for each plug is connected

6. Remove all tools, rags, mates and other crap out of engine bay and start the engine, if everything is correct it will run smooth as! The whole job is very easy in the VT - VY models since there is a lot of space along side the engine.


You will see we have chosen Iridium sparkplugs, this plug type allows us a much greater tuning range before we run into detonation issues. The old plugs are just fine for everyday use but will not cut it when the serious stuff cuts in. Most Raptor kits are supplied with Iridium sparkplugs so the owner will achieve his best performance.


Small task 1 completed

I have them in mine and they are great and supposly last up to 80,000kms with them. I think I paid $12 each with a trade discount so its not too bad.

Developments so far this week

Below you will see the recommendation for our VY by HM/Perry. We will be going with this recommendation from the people who know and take it from there.

Once the goods arrive and are fitted we will put some pics up



Recommended system for vehicle

HM8TCSS – Stainless Steel header with 1 5/8” primary pipes to suit twin cat setup.

HM718 – Twin high flow 2½” 1.7 litre Delphi cats with pipework and flanges to suit header and change front muffler flange to V8 position

HM8TIRS – Mild steel dual 2¼” front mufflers converting into single 2½” rear muffler and outlet complete with chrome tip.

I recommend this configuration for the described vehicle to provide good low down torque while maintaining high end performance, in our vast experience in dealing with these vehicles we have found that these pipe sizes have proved a very good package for all round performance.

The stainless steel header comes with a 10 year warranty, we do not recommend using anything but stainless steel in front of a catalytic convertor. The catalytic convertors used are the same units specified for our V8 systems therefore offering more than enough flow for this particular vehicle. And lastly the exhaust system specified merges into a single pipe as we have found that a full dual system on these vehicles will sacrifice low down torque required for a good all round performance

Today was dyno day for the completely stock VY V6 Auto. Numbers appear normal and decent enough for the supposed 152Kw that Holden quoted for this model

We printed out charts in both KW and HP so you should find something which suits your preference

You should find pictures attached.

Hey Tim, did you gap your plugs?

[vyyoot]

Tim,
It's Matt in Sydney. Good to see you bought yourself a VY! Can't wait until you get the kit sorted, so I can finally get it on my ute!!
