but the engine is now in and running.....but whats the offical power at the wheels ???

[j3ned]

wanna see this go at the pod - cant wait to beat him :wink:

[northy]

lol....i carnt wait to see if nick reads old one has any potential left in it.....12.5 ??? pah :wink:

[J o n]

I dont think Yoz's will beat Mehdi's time, think it may equal it at best, but it would be nice to see an NA Clio break into 12's

[FlamingMonkey]

I'd imagine the car is setup for track though not 1/4 mile, look ace though

[northy]

that empty engine bay looks really clean for yoz's car :wink:

[j3ned]

It is a work of art and i wish Yoz2a well on his path to fame and fortune - just watch were your standing though in future mate - lol

[Fred]

229bhp BTW (done on an engine Dyno, so as gospel as it gets i guess)

178lbs/ft i think too

i think it pulls 140 lbs/ft from 3000rpm!!!!!!!!!!!


its quick

[northy]

at the fly mate ?

[Fred]

yeah (i'd say from the picture, thats quite an accurate measurment!!!)

[northy]

class.....whats the reading at the wheels then ?

loving the colours of yozza sport.

[Andyvalver]

Id say it will lose a bit of power when the full exhaust goes on and when its in a hot engine bay :wink:

[skipp123]

that thing is ****ing insanely loud anyone who has seen the vids on cliosport will know what im on about!!! id like to have seen the invoice for that lol any one have a rough idea of cost? when i get me V6 itl have the tb conversion there producing!!! :twisted: :twisted:

[Fred]

we actually"gained" 4bhp when it was fully assembled in the car

don't quote me on this, but i think it made 178 at the wheels

[northy]

lol thats good.

mine is producing 177.5 at the fly :(

[J o n]

mine must be 200bhp then ;)

[northy]

lol...not at the min its not pal.

well done GDI and yozzasport.

[BenR]

thats class.

No problem, but you'll need a megane head.

I can do one for the williams head, but its not as good overall.

[northy]

sorry ben

Megane heads are cheating.

I WANT FULL WILLIAMS POWER.

U fancy making a conversion kit ?

[2 live]

lol...if u want full williams power...why bodies/cams etc.

full williams power is what u started off with..before all the mods

[northy]

lol....williams head, internals and block i mean mate....

megane is cheating.

[2 live]

y?

same block



heads required for port shape more than owt else with bodies, as iv explained to ya b4 numerous times lol

not cheating by using diff manifolds etc ?? lmao

[BenR]

like i said, i can do a kit for the Williams head no problem, but they just dont make as much power.

The williams ports are so big that tapering from a 45mm dia hole to the monstrosity that is the williams inlet port leads to some very unfavourable flow characteristics. But you can certainly still run bodies on a williams engine.

[northy]

whats the comparrions ben ??? williams over megane ?

[northy]

y?

same block

I know.... :lol:

[BenR]

whats the comparrions ben ??? williams over megane ?

comparisons?

bottom end is essentially the same performance wise, so ignore that.

The cylinder head on the megane has a much better port design, and the throttlebody system you can fit to the megane head is much much much better than those you can fit to a williams large port head.

Thats the only reall diff on this matter.

[GDI]

thanks for the comments chaps.

it was several weeks of hard slog.

The engine dyno was used to provide accurate power figures and give us the best chance of mapping it as accuratly as possible.

the dyno showed peak power of 225 bhp at just under 7100 rpm

this engine is still very much in road trim and provides 140ft/lbs from 3000 rpm rising to 173 ft/lbs peak at about 5500 ish... cant remember exactly.

its odd to drive on the road as it pulls with such linear power that you almost dont notice until you see the speed...

with different cams in it would make more as these cams are very much based on the road going version of this engine...

we are pleased with the result, and are currentlly working on a similar project but without individual TB's but a single Jenvy body and a kinda kunky air intake system... run on Omex and the same cams as in the orange engine.

more info about that fairly soon.

its aimed to be ready for the TunerGP later this month


Great site lads, if you guys need anything please let me know
