usual benefits of quad throttles will be from having the throttles closer to the engine, which results in better throttle response.
when the throttles are wide open, then it is similar to a normal setup, as you have the runners which give velocity etc, but the difference will be the response to throttle opening..

ok cool, i often see quad throttle setup's without any form of air filtation. whats the deal with that? Are people just willing to gamble nothing will be sucked into their engine? or is it very unlikely anything would be sucked in??

Only for show because the trumpets look hornier than any turbo I have ever seen. Most people put 'socks' on (easy), and some will make up an airbox to go over the lot and then use a panel filter and CAI to feed cold air (requires a degree of effing around).

I'm stuffing around using the quad throttles on my 4ag turbo, but won't have it done for a few weeks yet for various reasons, when I do, I'll write something about it stating any differences I noticed.

Hi all
hehe, i guess not many people has done this, besides Bill. Well i can get adaptor plates for 20v qtb to match bigport, but its too expensive at $450... This is first step though. Then another $400 for the actual 20V tb. $20 each for the trumpets. This is the furthest i've been. Anyone care to share their knowledge, as to the other linkages.. fuel lines etc.. ( im so frustrated ) affff !!!!!! Any manual or tech articles would be helpful.

Why is the adaptor plate so expensive? Isn't it just a plate machined up?
I've heard that the stock computer won't run the quad throttles well, something due to the way that the 16v controls the idling etc, I'm not sure.

I would like to know what steps are needed to prepare and install the 20v qtb on a 4age. Anyone know of any articles or something like that.

Do you think this mod is worth the money and the hassel of installation?

With a stock engine - yes for power and sound, no for cost.
With a modified engine yes to both. Especially as it allows you to go a lot further with the mods later on.
You'll also get better fuel economy with a well tuned computer.

Bill: Will the standard 16v computer run with the quad throttles? Or is Club4AG accurate in saying that it won't? If it doesn't, will the 20v computer run it then? Or do you have to go with aftermarket programmable?
Thanks

Bill,
I currently have 4age,big cams (not sure on size),larger injectors,haltech computer and the usual exhaust mods.
Will there be a noticable difference in power with the qtb over the standard throttle body?
Any other info you can give me would help me a lot

all. a set of quads will help with big cams ect due to better cylinder fill/speed - something a big single TB wont' give u.
a std 4AG computer won't run the quads. aside from the injectors being different impedance, you have no where to plug in the map sensor, and depending on what ECU you use, (100kw or early 86kw type) you've got TVIS in the way
re: adaptor plate, something that can be machined up yes, but, will be very exxy this way - go to the wreckers, get an old 100kw or 86kw inlet manifold (depending on your application) - leave about 200mm and chop it across wise and TIG a plate on there, then, bolt the quads to that.
also bear in mind bill runs a motec aftermarket.

I'm just putting the finishing touches on a QTB setup for a mates bigport rally car. The car is using a Haltech and some aftermarket cams (280 I think). With a little head work and the throttle bodies, the engine gained 20% peak power along with a nice spread of midrange torque. I'm expecting a little more with some debugging and fine tuning this weekend.

Demuire, yes the stock small port computer will apparently run with quad throttle bodies. There's a guy in the US that sells a kit where he does that and I've read of no complaints. I can't see how it would work well, but everyone says it does ....
Krayzie, yes, you should pick up a bit more power everywhere, especially at higher revs. Better fuel economy as well.

is it really that hard to get quads to work on a 4ag?
I can understand that the tvis engines may have a fuelling problem,but surely you'd use some form of fuel only ecu,or would replace the lot to get the fuelling correct anyway right?
I don't see how the std maps on either an 86 or a 100kw 4ag would be anywhere near close to correct once you added quads,and exhaust,cams,etc...
the engine would likely run with a 100kw's ecu,but I doubt you'd ever get the best out of it.
as for the maps sensor throwing a wobbly,surely some one way valves and a small vacuum tank linked to each inlet runner would give you a proper signal?
as I see it,the hardest part is getting the things physically on there. once you have a manifold,the throttle cable and such done,your only problems would be working out how to get an idle air bypass rigged up,and getting decent size and length trumpets onto the thing.
bills' engine above runs the 16v's injector setup,so I'd assume his manifold adaptor is fairly simple.
I'd love to get a hold of something to make the Tb's fit,as I already have a set on hand(attached to a complete engine in my garage),and am in the middle of rebuilding a 16v for my daily driver. I'd be keen to give a quad setup a try...

I think you should talk to Zack at Cypher in WA.
http://www.cypherindustries.com.au/front.htm
he makes kits I believe for ITBs for the 16v

Bill, I have all the aluminium plate and pipe. My questions is how the hell do you cut the 10mm plate? Its damn think and I dont know how I should go about it.
Anyone have any ideas?
Also where to get the trumpets and socks for the qtbs?
|
I got a plain electric jigsaw and used a medium type blade and just hacked it out. Then spent a lot of time on with a file getting it all straight.
These days we have a milling maching at home, so I just use a moveable table and a mill head to get the angles & lines I need.
My inlet doesn't use conventional trumpets, they're a 'thing' I made up myself that gives the engine a little more power, and are also made at home.
I got the socks at a motorbike shop.

Bill,
Would you have a pic of your version of a trumpet? Or what you used to make them. Im not worried about the looks the car is not going to be a show car I would rather have performance.

Internet problems for a couple of days, sorry.
My trumpets don't look anything like those ones in the Club4AG threads.
They look more like these -
- Though are slightly different again.

I will probably get some machined up by a friend. I will try a few different design but I dont know wether it will make any difference or not.
I'll keep you guys posted.
