420 RWKW with standard engine internals?

[Falchoon]

Probably is possible to make those sort of power figures but I dare say engine life would be decreased dramatically.

[Trumpy]

APS have already answered/addressed this question HERE.

Chris, Just to clarify the power figures.........what you are quoting is WRONG, the power measurement at the show is Horsepower not Kilowatts, so the additional power we are generating over the stock Phase III system is approx 70 kW's.

The stock Phase III power is approx 330 to 340 kW's on a manual trans XR6T (on 98 RON fuel) and the APS phase III + car is generating approx 411 RWkW's (550 RWHP) there is nothing to difficult to understand regarding this power level other than poduct development is always ongoing at APS. 

Now I have said a number of times that this APS XR6T is a Phase III +..................... and that there is another component added to the Phase III system to generate the additional power. Power is a by product of air and fuel combusted efficiently and APS is doing the best job possible to assist this this process, with a stock engine other than improved valve springs. 

You wont have to wait much longer to read about the APS XR6T and the additional APS component and or components which we will release in the APS Phase IV system.

With regards to the C and V XR6T that ran the 10.9 pass.......... there is no rule against using better/higher octane unleaded fuel that I am aware of in drag racing..........all SERIOUS drag racers that I know utilise higher octane fuel........what's strange about that.............your a racer Chris and I'm sure you are aware of this.

PS Spiro my apologies that your thread has gone way off topic, I will do my best to keep it happy. 

Obviously they are not going to detail the extra components until they are ready to be released. Instead of the constant barrage, why not wait until details are released, and then contact APS to ask questions to your hearts content?

love your work hoon :lol: :lol:

im2qk is slow at answering questions .......

hi all,

Yes engine life would be umm interesting

As for a Phase IV component adding 70+kw .... that's some component

Everyone knows the block core shift with these engines is bad and rod integrity no better sooooooo a 400% increase of boost pressure = what

Remember stock boost is 6PSI

cheers

If APS has achieved 420rwkw then I think it's pretty obvious that it's possible.

There of course would be an increased chance of failure. But the same can be said for putting a phase 1 on to a stock engine. But that's the chance the owners of modded cars take and accept.

IM2QIK,

I agree it is interesting to see that they've done it... however, that's more from reading what people have done with their cars on these forums and the power levels at which they start modifying internals.

Do you have more experience than that on which your asking this or are you in the same boat as me??

Cheers

Hi Jteal,

Thanks for your concern also ... much appreciated!

If you think I'm comparing pen*s sizes all well and good; for you need to stop being an true believer and question some of these claims.

Yeah it might be possible to produce 420 RWKW with a stock XR6T engine on 98 RON fuel soooooooooooo you try it and get back to me 

Cheers

Mmmm... maybe I will :lol: (tongue firmly in cheek)

Please Note ... I neither believe or disbelieve in APS on their claims of 420RWKW ... I am happy to wait and see ... comments like I am some sort of APS disciple is the problem with this sort of posting ... especially when clearly you have a competitors mods on your car ... that you may or may not have an axe to grind was the point I was trying to make ... I was just not sure of the posts motivation!

Please this is just my opinion and I am very often wrong

Have a good day!

is that it ???

block core shift .... inline six .... huh ... wtf .... explain that one more

rod integrity ..... everyone knows what ??

facts are very important ..... what are they and where do we find them ??

can anyone help ??

[ktford]

Be interesting to know everyones thoughts

I for one hope it is possible, will make my intended 300 rwkw's a walk in the park.

Wasn't this 420rwkw motor built at this stage for dyno days....dyno motors aren't supposed to last are they..I was of the understanding they were rebuilt fairly often

Probabaly off track a bit

I've heard of a XR8 running 420rwkw with stock internals.....do they have stronger pistons, rods than the turbo motor???
