Big Power. What Are The Cons For Over 300rwkw

[Crazy F6]

Ok it is my turn to my 2bob with in.

I have a Typhoon with APS stage 2 kit 300.5 rwkw that was fitted at 3000km

I drive my car hard all day every day it had its first drag outing 2 weeks ago

and it ran 13.5 at 109mph with wheel spin in 1 and 2nd

I will be going again when I get my clutch fix.

The only problem I had was the gearbox crunching in 2nd and 3rd so I told them

That I changed the gearbox oil and the oil I used transmax z

well did I have dramas with the ford and fpv told my dealer that this is is not the right oil so I was on a mission to prove them wrong so with the help of Ben at Mal woods we proved them wrong by the way thanks heaps Ben.

in the end it is the clutch making the gears crunch.

so I have made my mind up thanks I will be going to 330rwkw

but I want to make sure that the rods in the phoon are stronger than standard t ones.

Other than that I have not had any other problems with diff and cv joints.

Does anyone know how much better the rods are in the typhoon.

I have a PhaseII aps kit and mine makes 294rwkw on 11psi.

I do have the 968 injectors and bigger pump.My auto has shown no signs of truama at this power level and engine doesnt use oil and is quite.I know that is no way of telling if I can go more power but I will take the risk and up it to 330 +rwkw.

Also as long as I use 98 ron fuel I have had no detonation issues at all.

Steve ,

While you had it stripped down, I would have put the LP rods in it for future power upgrades. 

Nice little bit of insurance

Hi Macka,

I did better than that

She should be right for my future power upgrades now

Good question. I can only assume that they are. How much better I don't know. I believe they are the LPG rods, so the best question here is to ask why LPG engines need stronger rods (detonation is perhaps more common as well as pre-ignition). Given that the standard rods seem to be able to handle around 330rwkw you would probably be OK but Id look into it and ensure the engine is tuned as well as possible

Hi FPVT6,

If you're aiming for 330rwkw I believe you would definately need to get the phase III system including larger intercooler to ensure the engine gets colder air and that you can control boost (boost kit/actuator is included in phase III). Beyond that you also might find that the 968's don't run 330rwkw at a good duty cycle (ie too high) so you might need to have them adjusted professionally for higher capacity flow.

All the best.

LP engines run higher compression ratio is one reason. There are others but what bearing or extra stress they put on the internals. I do not know. But there would be reasons.

I have the 968's in my car which runs 328rwkw's and have never had an issue with the injectors not flowing enough. I'd reccomend a bigger fuel pump if you dont already have one though.

I'm not sure on what rods the Typhoon uses but if they aren't substantially stronger than the ones in the T I would definately be upgrading them. I know HPF don't like going over 300rwkw's with standrard rods. Also you have Robin (xlnt or similar) who bent his rods at around 350rwkw's and is having a rebuild.

Geea.

I think you are runn a malpassi rising rate regulator though Craig so this would be increasing the fuel pressure to the 968's. I know that APS believe that the 968's are close to done at 330rwkw.

Hi Craig,

I know my 968's are flat out making 320rwkw at decent duty cycle so they will have to be changed for me to move up in power.

As for the rods, yes Robin did have problems although he was running 360rwkw and at a higher RPM limit. I remember reading a post here that stated rods are at their most vulnerable when hitting high rpm under little to no load on the rears then suddenly dropping rpm. This is what happened with his car when he lost traction and hit the rev limiter then bang.

Mine were fine at 317rwkw but I haven't been treating the engine harshly. Either way an upgrade over 330 would be recommended

Ive noticed an increase in rear tyre wear

Ive only had 300+rwkw for a week now, but no problems yet.
