What did it cost you buy and to fit? How much power is it making?

As good as all the new people on this site say they are I refuse to believe they can outshine a well sorted turbo system.

Prove me wrong.

It's all horses for courses. He qualified what he said... "for what I need it to do". He doesn't have to prove anything.

Having said that, what I'd like to put on my car is a well-sorted turbo or positive-displacement blower for the big torque from idle through to top-end power. But realistically I can't spare my daily driver for the length of time necessary to get it all sorted and the driveline upgraded to make it daily-driver reliable.

So I've gone down the path of mild mods to improve the bottom-end response and will add a centri blower to fill out the midrange to top end. I can do that in my shed in a day. It'll be immediately driveable and the only major issue to sort will be the LPG system.

Will it provide more performance than a well-sorted turbo? Probably not. Is it more practical and powerful enough for a daily driver? Definitely. How do you define "better"?

BTW I have a turbo and 6boost manifold in the shed, awaiting the right project car... probably an NU Fairlane in dark metallic grey for a mafia staff car... one day!

How is that qualifying something when we don't know what he needs it to do?

Back in the day if someone compared a powerdyne kit to cheap turbo setup they would get shot down. I dont see the huge difference between the raptor kit and the capa stuff other than the bunch of new people on here pushing the product.

Are you saying that just because people are new here that somehow their opinions are less valid than yours? That sounds more like an exclusive club than an open, public forum.

He's just excited about his new toy. Haven't you ever been excited?

Thats not what Im saying at all.

I just think if people want to promote something or inform others about how good it is then they need to be more descriptive than just saying it does what they want and its better than any other option out there.

But he didn't say (in absolute terms) that it was better than any other option, just better for what he wants.

So maybe we should ask cooky just what it is that he was wanting when he chose the Raptor kit.... your turn cooky!

BTW I'll try to be a bit more descriptive and informative when I fit mine. I posted in another thread that I was particularly interested in seeing what (if any) gains were to be had between 2000 and 3000rpm so I'd posted some NA 0-60ft times for my car on AFF to do "before" and "after" figures. I just realised that not everyone here has access to AFF, so I'll repost the numbers here too.

A daily driver that won't overheat in traffic or on a hot day,big long torque curve,seamless power from the get go,something under the bonnet that you can show your friends that you don't have to show where it is,no plumbing to the unit that can s**t itself,a cool noise that sets it apart from everyone elses terdbo,uniqueness of set up as i have some ideas like plumbing air conditioning through the Super gearbox,and finally something that can run a 70K FPV something or other as it's already done this without dyno time to sort out and fine tune the system as it's on the GENERIC edit tune that came with the Raptor kit.
Turbo fit the bill? No way on earth,don't get me wrong terdbo's are wicked but you have to drive them wicked i know i've had a few.
They basically saved the diesel from going the way of the Dodo and for a younger bloke they're great but for me i need what this guy at Raptor said it would do and it did it damn well.
I rang dealers for every brand of forced induction in Australia and OS for a unit to fit my needs and i'm a very happy little monkey to have stumbled across this set up..
Feel free to sqeak up my friend.

Have you driven a well set up turbo falcon?

If someone builds a turbo falcon and it cant do everything you say your raptor can do for cheaper and with better results then they have done it wrong.

Ive had 3 and not one has overheated in traffic, not one didnt have a long torque curve, not one was not responsive from under 2k rpm.

Opinions are great but spouting them as gospel misleading others is just wrong and a bad way to sell a product.

The only thing I can see the raptor has over a turbo setup is underbonnet heat which isnt hard to overcome and the ability to fit it in a few hours. tapping a sump and making a custom dump pipe kills the install time on a turbo setup.

Get some dyno graphs up when you get some.

all this talk of boost /psi has anyone heard of effective compression ratio????? it a math formula that can be applied to an engines static comp + boost = effective , now unless you want to run methonol on the street , you better not have to much effective comp because the only way to stop an engine with to much effective comp from detonating itself to death is to flood it with fuel and or retard the timing heaps , neither of these options make power, take my au2 motor 9.6:1 stock add 7 psi and now my comp is 11.3:1 thats all the boost i want because it runs 98 street gas

Yep, lots of handy little calculator on the net that'll culculate the recommended compression!
matter of fact, last time I done a calculation, it worked out to be 14.3 or something. thats 9.6:1 running 7psi at a altitude of 10ft. can't bloody remember the link to it.

Some dodgy calculators on the net too. I've seen one that works out boost given engine and charger capacity, engine revs and charger drive gearing, that's more than 30% out.

Those 2 examples above for 9.6:1 static comp and 7psi can't both be right if one says 11.3 and the other says 14.3 LOL.

Easy to see how 14.3 comes out. 7psi is a smidgin under 0.5 bar. 9.6 times 1.5 is 14.4, so that calculator is just multiplying static compression by absolute pressure. I didn't think effective compression was that simple, but I'm open to be proved wrong.

Nonetheless, the same inputs shouldn't produce answers of 11.3 and 14.3. One has to be wrong.
