Williams on throttle bodies Pics

[Andy GDI]

Just finished a project car.

Williams Engined Valver with Jenvey ITB kit and Omex ECU and Race loom

Made 45 bhp more than std with Kent cams (not sure which profile as they were already in)

pulls very nicely above 5k revs, redline at 7000 rpm as the bottom end is quite worn (due a rebuild next yr)

Would have made more power as it was making peak power at redline....

 

[Russ_16v]

nice,what was the power mate 205bhp? any wider shots of the engine bay?

 

[Mark One]

nice job, would like more pics/

 

[2 live]

lookin good mate.


wots with the bolts thru the rad tho??


mine had the injectors quite a bit further forward than std hole for em in the head. redline at 8 ish i think. the dodgy webber ecu was giving dodgy readout for the rev counter, was only reading 1/2 , had it to 4.5 but it didnt sound very willing lol.

 

[Fletcher]

any pics of the whole car?

 

[Andy GDI]

uses std injector position

probably make more torque with some better atomising injectors

bolts are holding the race fan in place.

 

[Fred@BTM]

are these no good then?

^^Mines got those plastic ones. How come the manifoldis really long, and the trumpets short? Where have you got the air temp sensor fitted on these?

 

[Fred@BTM]

air temp sensor is cable tied to the fuel rail, use your eyes boyo!

 

[mini-valver]

Behind the breather hose. I see now, lol.


Say I wanted to fit TB's to mine, what do I do about MAP sensor, does the TPS sensor take over?

Yep run TPS as primary load sensing. Idealy some sort of Barometric sensing is handy to take into account changes in air pressure and altitude although you can get away without it if you build a bit of 'room' into the calibration.

Be more like 225ish wont it, my Williams with Kents is pushing 180+ so another 45 on top of that I would of thought, at least thats what it says

So I'd just unplug the MAP hose form the Ecu (running VEMS standalone) and hook the TPS wiring up, and put the air temp sensor somewhere? Other than mapping, thats it, right?

Until the airbox is fitted..... then it obviously goes inside it..

also the breather pipe is just there until the gentleman concerned fits his catch tank.

 

[mini-valver]

Knew about the sensor going in the airbox! Toying with a set for mine.....

 

[Andy GDI]

to change from MAP for load it would need a different map totally as the load values would be different.

 

[mini-valver]

I'd want a complete new map anyway to suit the ITB's. Just making sure I dont need anything massive changing on the wiring side of things....

 

[Andy GDI]

should already have tps wiring, not sure how the vems works, but usually you can switch how the load sensing works..

 

[mini-valver]

Yeah I have TPS wiring there as the Mk1 172 TB uses it. No idea if you can switch the load sensing though. Guess I'll find out if and when I get some, lol.

 

[stan*]

Yeah you can on the VEMS, from speed density to alphaN.

I would ditch the VEMS personally in the process though...

Did you find the spec of the cams Andy? Probably has the part number stamped on the end of the exhst cam.
Sounds about bang on right for a "nice" set of cams, they typically make about 200bhp with them.

ah sorry i read it as 45 over a std willy

That rad looks a bit pikey being 'secured' like that. Would vibration not damage the cores?

well you cant see how its secured in the pics, so i am not sure what you mean..

if its the bolts you refer to, they are holding the Pacet fan in place.

 

[Gaz_]

Couldnt you have done something else? Looks a bit pikey bolted through crushing all the fins imo.

 

[Laine_16v]

Sorry to rake this back up aswell, but isnt that a Renault 19 cylinder head? the little bolt head (thats been used to blank off the CTS hole) suggests so.

Not a full williams engine? fail

 

[cliotoris]

Agreed. And isn't that a Renault 19 head

It's in a valver anyway. And it's definitely a 2 litre head. Might be a 19 stat housing. Prima built it up years ago originally, I just rebuilt the head

 

[Tigger]

Looks really good that

 

[midge]

if it made 45 more than standard then it would be 195bhp.

standard williams engine is 150bhp + 45bhp = 195bhp. hope people understand now!
good result.

Whos car isit? anyone we know? how much that lot cost?

 

[sideways danny]

not a regular off here

cost wasn't straightforward as it came in running on 3 and smoking REAL bad. We'll be calculating a kit costing some time soon though.

 

[D4N13L]

Is this the one in PFC next month?

 

[sideways danny]

nah, that's Bex own RSI. This is a customers

 

[midge]

ahhh this is the one from williams clio that went in a long time ago isnt it, was going to get the at setup?

how much do you charge for the itb manifold

 

[sideways danny]

we dont generally just supply individual bits, so i dont know exactly. About £185 I think
