Raptor Superchargers Project Car VY

[hinterland]

Hinterland

You are welcome to elaborate on the vacuum pump idea, I am sure most people have no idea what you are getting at.

All yours to say ...............

there preaty basic really run of crank and recomended that they are geared to run at 4000rpm max so 2 to1 would be safe setup there aim in life is to create a vacumn in the motor instead of preasure which aids in making the rings seal this is where the h/p is picked up from also prevents oil leaks there only draw back is that if to much vacumn is created you will have to run a blead of valve so that around 3merc is obtained to prevent seal damage and lower oil preasure. most good dry sump setups also do same job as the scavange lines create vacumn as well.old toyota motors used them which will work but arnt anywere as good as the purpose built performance ones.so for anyone interested do search on the net and you will find plenty good info on them and pricing if nothing else it will make a good read.

What's wrong the the old fashioned way of running a 45 degree line in the extractors? and sucking the pressure out that way (apart from being epa unhappy:P )

[Raptorsc]

Sucking AND blowing all good for power!!

Anyways, the Raptor kit has its eye in on the ECOTEC on the VY, its wanting to jump in there right now and sink its teeth in

Need to T up the ECU work with Chiptorque which is going to have to wait a bit longer yet as they are moving shop at present time.

[Tuddles]

Not bad at all can't wait to see what it pulls when the charger goes on (my title maybe under threat)

[VY S P Plater]

Sounds like good work from the guys at raptor s/c.. I cant wait to hear more information on this project as progresses. Will you be selling this set up as a kit or is it just a test? I am really interested getting something similar on my car. Keep up the good work.

[Raptorsc]

This will absolutely be a full line kit for Raptor Superchargers, that means yes you can order one (VY V6 kit) anytime after the tuning is complete.

For everybody's information the VS - VT kit is mechanically the same as for the VY, well proven to make big power and reliably. For the VU - VX -VY its all in the tuning.

[Raptorsc]

Tuddles mate

Things are looking good for a challenge but we reckon the auto won't let us have the last few Kw it will take to beat you. All our systems are tuned as best as possible and consequently you will be hard to beat and its not possible to tune any better than we already do

correct, morroso do a performance vacuum pump, but they aren't cheap. if you are going to run one, i'd suggest getting low tension rings as the vacuum pump does the work to seal the rings. some good hp can be made this way. a better option would be to fit a 3/4/5 stage dry sump system but they are big bucks but lots of benefits, especially on high revving holden V8's which tend to pump all the oil into the rocker covers when kept at high revs for a long time

Youre talking about a 'vac-u-pan' system, they work well in the right application. You are correct about emissions PLUS if you have glass pack mufflers, the oil residue can clog up your exhaust. I prefer the dry sump method. Kills two birds with one stone.

[Raptorsc]

Well just one more sleep and we get to test the gains from the rockers at the strip, thunderstorms are predicted Thursday night but hopefully Friday night is good

Nothing like test and tune to make the rain come down

Facts and figures should be here on Sat morning.

[Johnsy]

Do you guy's have anything for the 3.6L alloytech ?
As my wagon needs more grunt

And what about LS1's ? after my edit with my sedan i will be looking for more kw's...

Cheers and good luck with the VY

[Raptorsc]

SSZ

We very certainly have a system for the LS1, expect us to be saying a lot about this in the next 2-3 weeks and we are also switching from trial mode to full production mode for the LS1 kit.




The thread link is here, looks quiet at the moment but not for much longer

LS1/Gen 3 5.7 liter kits

[Raptorsc]

Well finally the times for the rocker and exhaust combo have been run.

Temp was 27C and Humidity was 70% at time of runs, we feel this took the edge of the car slightly however as the night went on times didn't improve, the time slip shown is close to the cars best. Only a dry winters night would have improved times further. Our prediction of 15.2ish was a touch ambitious looking back after the test and tune

So to recap:

Stock: 15.65
Exhaust and extractors: 15.52
The above mod/s plus rockers 15.44

We ran 3 times and recorded a best 15.44. Total improvement from stock to the modded NA point is .21 of a second and approx 1.5mph improvement.

That's it for the traditional NA mods, the supercharger goes on next. Lets start of buy knocking of a whole second hey stay tuned

[immortality]

i think you also need to keep an eye on track temp as this can also make a big difference in your runs(traction)

[Raptorsc]

Immortality

Yeah good point, our test and tunes are at night time, we suspect the track temp remains fairly constant over the event.

We were reading a thread on Ford Forums of a lad who has done exactly the same sort of mods on a Falc 6 and with the heat of last week his times after mods were .1 slower than stock, if anything it serves to high light what the summer air/tracktemps do to track times.

I guess we could take the RAYTEK (infrared heat gun) along and monitor surface temps ........... next time maybe

[Raptorsc]

Just incase anyone thought we were joking about testing Pacemaker headers back to back against HM headers we thought putting up pictures of the Pacemaker header set we have here should assure all that it WILL happen

We are making a slight change to the intake pipe to the supercharger, it won't be noticeably different to the VS - VT pipe, just a couple of hidden changes so the engine cover fits back on better.

Otherwise trying to find a time slot to get the tune etc completed.

[Raptorsc]

Warning ....... the following motor image does not belong to the Raptor VY, the motor shown in image is a full on ECOTEC stroker.

Since the VY will be running same Raptor system we thought you would like to see an out of car motor with everything mounted, this way you can appreciate the quality of the Raptor system.

ECOTEC with Raptor system fitted, the belt is only loose because the aircon compressor is refitted when motor goes back in car then the belt will be all tight and nice

Enjoy

[1991_Vn2nV]

So whens the back to back test due for the Pacemakers vs HM?

[Raptorsc]

The back to back on the extractors will be at some point down the track after the blower is fitted.

The car is booked for tuning on December 6/7 maybe the /8th. Standby for more news

[tbblitz]

raptor got a few questions for you. I have a vs commodore 3.8 ecotec and i have these mods, pacemaker extractors 2 1/2 exhaust system with a podfilter. Stage 2 shift kit with 3,9 diffgears and minispooled and bigger throttlebody.
Now when i try and do burnouts in second gear it stuggles to hold second gear and slowly dies down and hits first again. this is with 15s on. im using normal unleaded fuel. Now ive been told to try the new bp racing fuel 100 octane with 5% ethanol and that might give me the extra punch i need. If that isnt the case im thinking about getting a chip and cam or even just a chip. All i want is to hold second gear then ill be happy. what do you think? any idead would be great.

[Tonsta V6 S/C]

A Supercharger would definitely help

In the meantime you may also want to try the FIT 1.97's, as you can see in the Raptor Project Car in the video and from the dyno how much incredible mid and top end the 1.97's bring. This will allow you to hold 2nd gear burnouts as the 1.97's keep the power in the revs strong as well as adding a heap more torque ... just what's required for those 2nd gear burnouts

Regards

You have same situation as 90% of all V6 commodore owners when a burnout is called for, you have plenty good mods there but you need high lift rockers as mentioned above to fatten the power curve, use in conjunction with BP ultimate 98 and you will should have joy Rockers proven and recommended for making some extra grunt.

Should that fail to provide enough smoke then we would have to suggest the Raptor ProStreet kit, this will allow you to play with throttle in second gear while watching the tyre smoke rise, you and mates will be impressed We will demonstrate this with our VY in the near future.

Hey there raptorsc!!

I just read through the 3 pages of posts, and may i say im very impressed with the results from the VY.

I was just comparing your before and after outputs, stock and then after rockers and exhaust. My VS v6 has very similar mods: YT1.8 rockers, Advance extractors with a single full 3inch exhaust setup. Stock, she pulled 109rwkw and recently (with mods.) she pulled a PB output of 129.4rwkw. I was a little devoed that your VY made fractionally more power, but VY has a little more from factory right? (147 VS, 152 VY?) So do you reckon my car is doing ok in comparison?

Great work on the VY, i'll be sure to keep reading on!!

[Raptorsc]

Yes you are right about the power difference between early and later models, the other thing to consider is (regardless of rocker brand) we are running a higher lift rocker than you thereby admitting more air into the engines cylinders to which more fuel can be added for more power output. You might be suprised at the difference between the power developed by an engine with 1.8 compared to 1.97 rockers.

Are you doing ok, well by our estimation ..... YES

For all the people following this thread the update on the VY is as follows, the software that a vendor had promised to supply our tuner did not arrive for direct flashing of the ECU. We will be going to Chiptorque as originally planned, timeframe ......... we were hoping before Xmas but that is looking so unlikely. Will bring these results to you ASAP. You may all wonder what we are so busy at, well this week we completed some kits for the darkside products, there is now a BA - BF 6 cyl Falcon kit with 203 RWKW @9psi. The VS V8 5.0 kit was tuned also yesterday, will attempt to put up charts for this ASAP.

[galahs]

So have the high lift rockers effected fuel economy?
