looks tidy, get some vids when its done!!

I will when done

by **lucasdemoley** on Sun Jun 25, 2006 4:01 am

Only just botherd to read this thread, and lets just say i'll be following it from now on! I love it when people go a different way, and it will be well interesting to see how far the zetec can be bored out!

top work!

awesome car mate, that injector set up looks amazing, are the secondary injectors placed there so the fuel/air mixture is improved before it goes into the head? love to hear it mate

Thanks mate thats what i was out to do to make it different as i was sick of seeing zetec turbo conversions been done, don't get me wrong i would love to do one for the orion and would of been able to build a 400bhp one with the money i've spent on this engine.
I've looked into how far a zetec can be bored, Mine has a bore of 86.5mm and know it can go out to 88mm with the help of liners or the use of a CGI block but thats just the bore as it can been stroked out aswell but i wouldn't want to do that as it wouldn't rev aswell. The best thing would to bore it out to 88mm and reduce the stroke to about 80mm from a 88mm keep it a 2.0 so it would be a higher revving engine.

Yes

They aslo add about 10 bhp without stressing the engine

looks very smart m8

ride height is just rite too, not too low..

by **freak power** on Sun Jun 25, 2006 12:05 pm

Its a drop of about 55mm

What kind of rpm would you think you would get with this? Thats nutts though, and pornography to the heavy footed!

That would depend on the custom cams that the engine would need

Such a clean car, loving the wheels, and those tyres! :aviator:

Its taken some work to make the manifold and the rest of the setup but it needs a few tweeks to get it right

Strut brace will be going to the power coaters and i also need to lower the engine to clear the brace

It'll be interesting to see how efficiently the secondary fuelling is drawn into the trumpets from such a great distance...wouldn't want fuel just spraying out into the engine bay! :lol:

When's it going on the rollers?

by **freak power** on Sun Jul 16, 2006 3:01 pm

Thats not a problem with the 2nd set as i've already sorted that problem :wink:

thats what im thinking!!

will be a beast when its running :devil:

by **rich_frst** on Sun Jul 16, 2006 3:15 pm

just looked at the whole project, fooking cracking motor mate.... like it alot :wink:

by **Mikee_RS** on Sun Jul 16, 2006 3:22 pm

crazy fool

by **freak power** on Sun Jul 16, 2006 3:24 pm

Thaks mate

The new inlet will flow much better than the other one and with the 2nd set of injectors it should give it a few more bhp than i hoped for when it comes to the mapping

by **rich_frst** on Sun Jul 16, 2006 3:25 pm

quality, bet it will fooking fly....

by **freak power** on Sun Jul 16, 2006 3:26 pm

Thanks Mr T but i'm not crazy :lol:

Are the pics of the first or second set you've done? What's the difference, and what problems did you note?

Usually, the second injectors (the ones far away from the valve) will only open at WOT and at high rpm. When this two conditions are met, airflow is really high and the sprayed fuel outside the trumpet will be sucked in with no problem.

Injecting fuel far away from the valve will cold down ACT's better and the air mixture will be more homogeneous which will help since problems can arise (fuel droping out of suspension) when loads of fuel is injected.

All F1 engines have injectors like this, and the "cloud" made by the spray on them is massive! No fuel spills out the trumpet.

I know that you know the reasons mate... or you would not go that expensive route

Hope that everyone can understand why another set of injectors should be used far away from the inlet valve.

Actually there is also other reason:
- When the injector near the inlet valve is too big, it will hurt low airflow mix (fuel will drop out of suspension and the injector injects too much fuel at low ms openings). Use smaller injectors and get another set far away to only help high rpm fueling.

Alot of people get it wrong when they see 8 injectors on a N/A engine as they think that all 8 will be running all the time.

by **BUTRE** on Tue Jul 18, 2006 9:46 pm

freak power :Alot of people get it wrong when they see 8 injectors on a N/A engine as they think that all 8 will be running all the time.

It all dependes were the extra set of 4 injectors are placed on the inlet. You can have 2 injectors spraying at the same time right at the back of the inlet valve(s), but this would only be aceptable if the injectores were really small and top-end will hurt on the mix due to the two injectors not flowing enough.

Only if you go above 500cc or so that you'll start having problems with low airflow speed and small injector cycles.
Ok, this is just a rule from where to start because there's alot more involved than just saying "500cc is the max for any kind of inlet manifold design".

This aplies to any engine, NA or turbo charged/supercharged.

freak power, I'm keeping my eye on this topic of yours. Very good tech knowledge on how to go for more power the right way! Congratiolations mate!!!

by **freak power** on Tue Jul 18, 2006 9:56 pm

We are going to have a play with the placing, bleeding of the 2nd bank in, and pulse tuning but i think i've go the length right for that.

Im loving this Freak its going to be a beast! :aviator:

by **Swanick** on Wed Jul 19, 2006 7:45 pm

looking quality pal, loving it

by **freak power** on Wed Jul 19, 2006 7:49 pm

I hope so

looking good fella, very good actually!

when do you anticipate it being on the road fully mapped?
