I expect to have some new power charts for this kit very shortly, really need em so people get a good cross section of power results people are getting.

Hopefully will have em in next 48hrs, will come from a customer who is going to a Bris Comms dyno day today.

Stay tuned

Long awaited for information that I needed from an independant source.

Check the chart, the low readout was a test run prior to the full power runs.

The ute is STOCK apart from extractors and exhaust, tune is generic Raptor manual tune.

We have another customer with 330rwhwp on a generic chiptorque tune .... not supplied directly by us tho.

This is HUGE bang for the buck and still easy bolt on. If you got a stock 5 and its got extractors etc but still not going hard, then this will wake it up big time. Really we are seeing gains of 100rwkw + here and tats decent, like sideways 3rd gear action.

Drink up the info, its been a while coming and this is from the ProStreet kit with the Raptor V supercharger unit

It made 242 rwkw. thats an auto with a stall that goes to about 3100 or so. was meant to be 2800 but the whipple makes a bit more torque then the cam i was planning lol. still with original motor never opened. does have a decent exhaust, pacemakers twin 2.5 inch.

I believe the power run was done when the car was hot. It is a great drive now great down low power and just keeps going. does not seem to run out of breath at all. best thing is it still drive close to stock when you want to but instant throttle response. I even let the other half drive it in the rain.

Looking to get it intercooled soon, putting electric fans on it soon, and have already opened up the intake which made a fair bit of difference.

next big step is to start building a 355 to handle alot more power.

Must say i've never been in anything with a raptor or similar kit so can't compare the two. except the whipple was not cheap at all, but i decide for me it was worth the money.

Yes horses for courses, how far one allows their budget to run will determine whether they can step up to the Whipple level. Thats reasonable enough power tho, what psi? Once you get a cooler on it engine strength will be the only thing holding it back from crazy stuff.

The 255rwkw from the unintercooled Raptor package puts a mark in sand on power per dollar and the ease of fitment for the DIY person is very attractive as it saves them a lot of coin.

i could search back posts but can't be bothered, so, how much is this raptor kit?

weedo_86 · #**131** 19-02-2008, 06:11 PM

$5400??? from memory with tune

Raptorsc · #**132** 20-02-2008, 08:10 AM

about 8-10 psi i think, i'ld have to check that to be sure, but yeah that start fairly low in the revs right the way through. real nice power curve (almost a straight line) to go with it.

when i saw the dyno results i was happy and worried at the same time. love the power but don't like gambling to much on the motor. I need a bit of time to get the money back together to build up what i want. Its scary when you start adding things up. intercooler, motor, gear box, diff, drive line, brakes, tires, etc. etc. plus trying to keep it all 100% legal.

Yeah money is everything. I had it at the time and i was always keen on PD supercharges and the whipple from my research is very efficient. Just so you know i didn't post about my car to try and convert the masses to whipple just that i saw my car had been mentioned and i don't mind chatting about it. The other things too think about it is for what its going to cost me for an intercooled whipple, people could build a motor and put one of your kits on it. it comes down to the desired end result and power level.

your kits where second on my wish list and i'm still reading up on them

looks like you guys have got this one sorted! id like to see a FMIC power, 15.4 is about right for a stock HSV anyway, anyone whose been to the track in a 5L will know this :P

i ran 15.3 stock, then just with a retune 14.96, and last time i went after my cam it was 14.9 (45 deg heat)

question, have you had time to run this kit down the track with the 220rwkw power figures?

Raptorsc · #**136** 02-03-2008, 01:44 PM

No we haven't had it down the track at 220 rwkw, only tried it at 188rwkw and that gave 14.2, and I will tell you right now that I cannot actually find that timeslip ..... just had a good look for it.

Anyhow we will start again with the 220rwkw and see what that makes. The local track here was damaged in the floods (Mackay) and hopefully in a month or two we can all race again

I would like to race a couple of customer cars with our kits on, they all made more ...... a lot more ...... power than we did. But that will never happen as the closest of them is 1000km away. I know in the winter one of them is going to try it.

Timo · #**137** 04-07-2008, 08:24 PM

Ive been considering blowing my 5L VQ stato for a while now and just stumbled across this. Very interesting stuff, am seriously considering the kit.
Just a few questions:
Whats the weak link in the 304 engines? Is it the rods, pistons, crank? Or a combination of all the above.

Secondly, while the power figures are pretty good i wasnt blown over. My N/A 5L has been dynoed at near 200RWKW. Its had some work done to it (not sure exactly as i bought it as it sits) including extractors, cam, headwork etc.
What would i expect if i bolted your system to it?
Note that its getting a full rebuild before being blown as its put over 100,000 on the clock since its last one
Cheers
Timo

Can you get my car into the 11's, just ran a 14.6 with a catback,cai and tune. 4 bolt main 5.0L HSV VP GTS 200kw stock. It does have roller rockers and a tiny cam from factory, 9.0:1 compression, will this work with or agaisnt a blower?

"The black motor consisted of VN Group A 4 bolt block, VN Group A "D" port heads, VN Group A crank and rods, flat top pistons with a revised compression ratio of 9.0:1 instead of the normal 8.6:1, double row roller timing chain, VN Group A timing chain damper, crane "gold" roller rockers, larger diameter lifter bores (like the Grp A) to accommodate the cleveland lifters etc.
