Help Required- Building Serious Power

[MrBean]

Ok, a few observations:

Get a seasoned block, something with probably 100k + on the clock. Have it sonic tested for uniformity of cylinder walls, thickness etc.

After that, debur the block, remove all casting flash, especially around main bearing webs. Properly chemically glean and degunk.

Same goes for the crank, stock cast unit will do, but same blueprint treatment as block - deburring of counterweights, chamfering of oil holes, would help to add some weight to counterweigths to better assist with balancing a notorious difficult engine - the straight 6.

Otherwise, go billet as Brian did.

For 500rwkw, there is only one conrod I would ude, that is Carillo.

Same goes for exhaust valves, not stainless, but Inconel. Get a decent aftermarket intake, and have a custom branch manifactured for the turbos. Yes, turbos, as in plural. Do something special, go 2x smaller turbos, better efficiency, less lag, bla-bla-bla.

I know you will get heaps of different answers here, but I discussed this specific point with Simon a while back, and he is in agreement.

Do something special, different, and good.

Stay at around 450-475rwkw, this way you will leave a lot less spares in the street. Above that and everything else, except the motor, goes to parts heaven. If you can, go to a decent auto, much lower shock-load on driveline components. But probably to much work.....

Have fun, keep us posted, and use/abuse what you can.

Br,

MrBean.

lol, the mention of sheep has nothing to do with my power, some members maybe... :banghead:

you probably do, but are u aware the T56 is ALOT slower on the 1/4 than the auto's?? ill admit I couldnt picture myself owning an auto... their just so bloody boring!

how could these engines go bolted upto a lenco?

TL I am of the same school of thought as BCL in this regard ( maybe cause we are both old farts- relatively). I want the fully rounded driving experience not just quick times down the strip. I would rather boil my nuts in oil than drive an auto.

Mr Bean, I think you might have missed the part where I said I already had the motor and pile of parts and the machining is finished......?

I would be very happy to make 450rwkw in a nice drivable setup.

As for the twin turbo setup I have to admit I thought about it but when it comes to heavy duty big $ R&D I am definitely not in BCL's camp ( or I suspect, income bracket). I am trying to keep it pretty simple, balance the compromises to suit my taste and not spend mega bucks.

However Í'd be happy to PM you my bank acc details if you would like to fund a nice sequential TT project!

By the way I read a peice you wrote a while back about your plans to get into the hex code on the Capa edit box and sort out a few issues, did you ever proceed with that and if so what was the outcome? Sounds like you know a lot about IT stuff.

[MrBean]

Rofl at Exit We both need some funds in our accounts ...lol.

Re the Capa flash box: I am studying CANbus, which has a counterpart in the Industrial world, ie Devicenet.

I am playing with that to try and get all the info we can on the Ford ECU, I am involved over at Fordmods with Lukeyson.

I will provide feedback on my progress, as things will start to move along now that I have my Carputer complete, installed and running.

Good luck with your engine, I didn't miss that you had an engine prepped, just thought out aloud.

Would be nice to do a TT setup. Jeeshhhh....Would really be nice.

Good luck, keep us posted.

Re the TT setup - don't a lot of Skyline owners pull two turbos off and replace with a single?

Prolly because they don't know better? In terms of lag-reduction, as well as volume for top-end use, you cannot beat 2 smaller units.

They might replace 2 with 1 becuase of cost reasons. Space, piping complexity, quite a few reasons, but performance ain't one of them.

I will play with this type of setup on my UTE when I start with my bullet-proof bottom, I will only go max around 450-odd rwkw, even though the setup would be capable of much more, in a streetcar there's not much point going more power.

I am looking at throttle response too, that's why 2x hairdryers is the route I will take.

Sorry for the off-topic, guys.

[MYWPN]

A single turbo system is capable of more horsepower that's why they do it.

[F6 RAPID]

I am here to tell you from practical experience, 500rwkw's is really useless on the street. You will get done everywhere as you just can't use anywhere near its potential in the lower gears. At around 450-470rwkw's, you still get wheelspin in third on the highway from 130km/hr (Don't you Shazzy).

Stick with your 450rwkw target IMHO - still useless, but not nearly as 500.

500rwkw's is good for two things;

1. Boast value

2. Scaring the beegezus out of people that are silly enough to get in the car with you.

And put at least 275's on the back, don't buy cheap sh!t tyres otherwise you will regret it and take it easy to learn the power. It really is quite brutal.

[turbotrana]

Two turbos are just headache and packaging wise that much harder to fit in and set up.

Nowadays we understand engine tuning alot better, we have complete independant cam control and better engineered setups that twin turbo dont offer that much benefit anymore.

[ZAP]

You can run 2 turbos in non sequential setup, the same as the new BMW 335i.

They run one turbo off 3 cylinders, and are independant of eachother.

I think if this was done properly, it would be faster than a single setup.

It would cost more and more complex, but would look great.
