it never ends for me ..

 

looks like a may of blown a piston ...

 

soo its forged time looks like

but gonna be off the rd for a little time and going to

miss some shows looks like :(

 

any one got a good bottem end with forged parts they want to sell ?

been doing some cleaning and painting today .. De oiled/greased

 

Painted all external items Black and Silver .. the Main Block is going Red to match the plenum

 

 

Now i Read somewhere that its wise to Tig/weld the 2 nuts on the counter weight on the crank as these tend to come loose ... what u guys think ?

 

 

Hi Mark,

A lot of stuff is belt n braces with these cars,unless your engine is cammed and will make crazy rev limits its pointless mate.

thanks for that ... i did wonder just thought i ask about it

 

the way it was said on the page as if its quite common for them to come loose and all so some thing about drilling out the oil way hole that has the pushed in bearing

tapping it out and using a Grub screw to block the hole instead

all so i'm thinking some new injectors in there .... 750 or 850's ?

any thoughts to this

 

will be looking to get around 600hp there about once i have finished

Im speechless

why ?

maybe i missed it but i thought you was doing a cheap rebuild and using stock rods which you said were good for 500 now you wanna top the dyno leader board.

 

You will need a considerable amount more done to the engine to achieve that a set of pistons and injectors isnt going to do that.

was .. but if u look on my last list got eagle rods down ..

 

my total Parts bill is £1577 to door

 

Total Engine Rebuild bill with Machining work and some used bits

and new Injectors

 

 

£2107.39

With the amount of time and money that Bob has put into his zed to achieve his dyno i think you are crazily optimistic if you think 600 is possible.

why ... if the engine is good for that power and more ...

tubs are good for 700hp there about

Mapping and injectors to flow the fuel

why not ?

 

May be a little optimistic but where would get/be if we wasnt

i would like 600 (Crank) but lets see

Marty Mr negative today lol!

lol well i see so many claims of big power and things are good for this much and so on and so on

 

However i know by simply looking at specs on other zeds that are running 600+ exactly how much work you do need. Simply building a engine and chucking it in isnt going to do it.

 

You ask whether to use 750 or 850 injectors well things like air flow starts to come into the equation and then mapping and so on. Not just put 850 enterprise`s in and get an extra 50 brake. A bit of relaistic management and full car planning rather than just the engine is in order.

750cc injectors should be ample for 600bhp Mark,I think the cc rating is the the amount of fuel the injectors will flow for the same bhp give or take a bit. DeatschWerks injectors are frequently recommended as being reliable, closely matched and flow what the rate they should. You will have to look into whether those particular injectors require any modifications/adaptors to fit the fuel rail or whether you are better off getting a new fuel rail as well.

 

What is the standard crank good for power/torque wise?

i do understand what your saying

just trying to sort out what injectors will flow right for that type of Power

i know sticking the big'st injectors in there isnt going to do the job right unless other

items are sorted first

and what i have been reading/told/advised its possible

but even if its 550fwhp ... still bloody good and not to far off my target :)

Quote ... of web sites 700>800hp before looking at getting mods done to it ..

aprently its a Forged crank anyways

and the only thing that can be found as a problem is the center weight is bolted on ( coming loose )

just had a little thought .... Exhaust Headers .....

 

are thay both the same design ?

AMS Max Flow $495 http://www.z1motorsports.com/product_info.php?cPath=6_19&products_id=3696

Mike Smiths MSP $695 http://conceptzperformance.com/Cart/description.php?II=1443&Car_Type=300&UID=2012052811501980.1.103.33

Mark... Step away from the computer before your mrs divorces you!

lol shes gave me the go ahead .. :) ... she has her hobbys and things i got mine she knows i'm spending 1700 whats a few more quid lol

AMS pretty much ripped off the MS design - supposedly porting them further to give slightly more flow - but essentially they are the same!

if you believe it here are the flow results:

i did wonder but there is a Mega saving to be had .. the only problem is all my order is from conz as Z1 are crap on there prices

way more on RRP ... and no discount what to ever ...

 

just trying to work out the cost ratio item plus postage z1 ...... or cost as postage is all ready done just need to speak to conz see what price

thay can do the headers for

thats a lovely chart but what does that actually mean in real life.

thats a lovely chart but what does that actually mean in real life.

 

its the flow rate of each port on the manifolds. There are other factors but basically the higher the flow the more capacity to run more power as you are removing restictions on the gas flow in & out of the engine

Yeah I meant in terms of percentage gains.

Brand of Oil ... Just Spoken to Opie Oils

 

and they have recommended Fuchs Titan Race Pro 10w/50 6lt for £60 delivered ... any good ?
