were back LOL throttle body zs
 

just a little tease

2-7k rpm in seconds? er.... what a project

that sound evil haha, whens test day?

sounds good.

Drew

Looks and sounds like a caged animal bursting to get out!

i bet you wished you had a grey zs now :whistle:

cheers all we are getting there (well G is LOL)

LOL looks awesome Ste

cheers alan

i here you wont a go in it

try and get a proper mounting for the ecu.

Drew

Its not finished yet, awaiting some parts from WSR however, Mr Bennets is in Shanghi so wont be this week.

G

Deffo m8 but only after you have driven it

i was saying to steve he needs a mounting for the ecu sorted, something for him to look out for.

Drew

obviously the best colour ;)

you going battery to boot? give you some space for the inlet pipe.

Drew

Got a slim battery for under the hood.

Hows your zs projects going Drew?

G

Yeah I do like grey, but I'm more of a hatch man myself

very well.

Drew

Talking to MG or on holiday?

What are the throttle bodies off? I remember reading about a throttle bodied v6 years age, is this the same one? Looks bloody awesome!

Hes running a car in WTCC there.

Mr Bennetts definitely wont be talking with MG again..

G

They are from the WSR v6 touring zs.

This project was started in late 2009. But there were many issues which hindered its progress which doesnt need to be brought up again.

Im sure Steve will post the final results shortly.

G

any updates ?

Only to say the cam belts have been changed before it gets a hammering on the rolling road shortly.

G

good to hear , when are the rollers booked for ?...cant wait to see the graphs.

I'm curious to know how this is running?
That's an airbox which replaces the OE inlet manifold, still looks to be running on the stock 180 throttle body so not an ITB set-up per say.

interesting point, its basically a plenum with no vis....which kind of makes you think it will lose all its torque...but still a great project and it will be very interesting to see the reality of the roller graph. Will answer a lot of questions.

some pics off xpf..

single throttle body into a plenum.

Drew

i never said it was itb or did i ?? thread was throttle body zs
we have tryed a zr and a zs TB and we have been told theres no or little difference between the two and may be going for a TOCA TB 60mm but will have to see

think it might lose a bit a torque but may gain this back due to the way it picks up the rev range
the magic graph shows all :)

yes i agree, might lose low down but if you gain some back up the top then grins all round :yes:
is the need of a correctly fitting throttle body holding it up then, it seemed to be running ok in them old videos :question:
I cant see a bigger throttle body helping it to make more power tbh but you never know till you try.
Hope your soon enjoying it anyway.

whats the size of the inlet on the plenum?

Drew

not sure drew

i think there are two options on the neck ???

ahh nice, hadnt seen the extendy piece before. you thought about doing a 90dgr to replace that, might make fitting the TB easier?

i just measured my zs TB at 55mm but its fookin long. if you cant fit that in id look at a T series TB @56mm.

toca tb sounds good but tbh its more money for little gain imo.

Drew

yeah looks good are you looking to pipe a cone down into the inner wing?

it looks like the strut tower gets in the way, as well as the dta.

Drew

will let G play with it and see what would be best for it anyway
the TOCA tb was not that much good price i thought thats if we get it but thats anther option if others dont work out as well

p.s i dont think the DTA will get in the way just a rough fitting

i know what G was going for but is a bit pricey

you cant leave the filter in the engine bay, piping it to the inner wing is £50 at the most.

Drew

The shortest route to the inner wing would be to the gap between the chassis rail and the inner wing under where the battery normally lives. You'd struggle to get an enclosed filter in there in a direct run but you could fit an open cone just the otherside of the hole, just watch out for deep puddles.

no not in the engine bay that would be silly

Maybe look at something like the ZT V8 70mm TB, have a simple adaptor plate made up.
If it's running DTA I've seen a KV6 with the VIS system de-activated and the flaps locked open, in fact I think Drew has the car now. It made very good low end torque even with all the stock inlet and it's flaps still in place, so with DTA you can map the torque curve.
I think with the increased flow from the inlet the the stock cams and valve train will be the limiting factor, to make the most of the new arrangement it would benefit from a compression hike and some nice cams.

What size exhaust manifold and secondaries are you going to run?
