I have a quad throttle in my EK4 civic Vit-R for long time, I have been installed 6 years ago, removed for few years due to feel too noise and reinstall back 1 years ago as I missing the racing feel again!!
it is a 4 x 45m OER quad throttle ITB with Microtech ECU
http://cartronicjapan.com/oer.htm
The ITB is very noisy if rev. above 5k, so I always keep it low unless want some fun and sure no cops around. soon I will make a cold air induction and airbox using piper X product for the ITB to reduce the noise so hope I can rev. it more on the street. http://www.pipercross.net/competitio...600_airbox.asp
But ITB give very strong racing feel, response and power, they are Excellent on the track.
I make 110kw on wheels, B16A with spoon cam, valve train, piston, megun header and spoon street exhaust.

wow, havent been busted by the cops yet.
got any pics of the setup?
-
megun header? new brand? wat pistons u using? nicee niceee
-
have once very close to busted, as I full throttle to rush for a traffic light that turning to red. I have full throttle all the way to redline (which is extremely noise), a cop suddently shows up stopped me, have opened my bonnet, lucky may be that cop don't know much about the engine (I have a pair of piper X grey colour filter shocks on the throttle, so not too outstanding) or may be he give me a chance. I didn't get charge.
I have the spoon's high comp pistons, oh and also a 3.9Kg B16A TODA flywheel (the earlier verson of TODA B16A flywheels that I install 7 years ago, at that time TODA flywheel is only 3.9KG but it was too light, so after a while they change to 4.1KG)
I don't have a pic. of the engine, may be take one in the weekend.

giv us ur list of mods mr173...everythin u done to engine...how much power?
-
mr173 was your car in hot 4s about 5 years ago?
-
mm.. ok... AUDM B16A with:
Intake:
OER quad throttle
Exhaust:
Mugen 4-1 header, local high flow cat, Spoon street muffer
Engine:
Spoon valve, Spoon spring, Spoon cam, Spoon cam pulley, Spoon piston, Spoon thiner gasket, Microtech ECU
Cooling:
Mugen thermo stat. Samco pipe, fluline alumium radiator
Drivetrain:
Toda flywheel, HD clutch
110kw on wheel, dyno at crydon motorsport few months ago (the engine now have some over heat problem due to once out of engine oil, at the time of dyno still no fix yet,so I think it can be better if I have rebuild the engine)

Quad throttle bodies are a waste of money unless you have reached the limits of the standard manifold and TB or you need more bottom and midrange punch for circuit racing. The money could be better used on headwork and the bottom end. Multi throttles would be one of the last mods to be done (if required as above).
-
who did the tuning? how reliable have you found it to be with daily driving?
-
I'd prefer not to say who did the tuning. But that person will never tune a car of mine again. But there would be no problem with running them on a daily driver provided they are set up properly (ie linkages) and tuned correctly. They "should" make it a nicer car to drive.
They will help especially when you have fairly big cams. With one throttle per cylinder they tend to smooth out the lumpiness at idle. But they are loud.
-
just asking coz i've seen 2nd hand OER quads dirt cheap around the place and have found it very tempting... even if only for a 2nd project
-
Weezer!! yes, my car was the black one in Hot 4 about 6 years ago!! Oct. 2000 issue of Hot 4, 6 years ago. Wow.. you are as old as me!!! haha.
Panda!! mm.. is that reliable for daily driving? my answer, is no!!! I agreed that Quad Throttle should be the last mod. for N/A, if you mainly on the street, for me now I would rather to spend the quad. throttle money for bigger displacement like 1.8 or B20+.
Grumpy Rooster! But back in to 1999, B16A don't have that much mod. option compared to now, at my mod. stage it was the last mod., I either go for expensive turbo (at that time turbo to B16A is a news, only japanese TopFuel can do it, all other turbo mod. available in OZ are for single cam honda only) I didn't heard anyone famous honda port and polish at that time. The only further mod. is go for 1.8 Kit from Spoon (bottom end) or quad throttle.
At that time no B20, no hondata, no ozhonda, no Toda cam, Toda header, (at that time Toda is still a new name, It still developing it's B16A flywheels, I have it's old version too light 3.9Kg flywheel in my car, no Toda sport injection system yet, so the ONLY quad throttle system for B16A is OER the old school brand name for AE86 years) and absolutly NO american parts for B16A, the state only have single cam, no no no... no Rocket cam, no type R parts (type R just launch), no JDM. ricer this term. Not like now, at that time mugen, spoon and Vision for Honda mod. is the only God! so quard throttle is the last mod. for me at that time!
=) yes I'm old!! haha
Now I just planning for my another major engine upgrade project after 6 years to my last mod. Now my plans is go to Dart B20+ tall block with 2.15L displacement B series engine rebuild, the only engine mod. part that I can keep is the quad. throttle. all cam, valve, spring, piston, ECU have to gone.
so I see quad. throttle is the ultimate intake system for N/A at that time. but untill now it's still the ultimate for N/A, notthing better than it in terms of enigne power and response, it give your car's racing feeling that is no other mod. can give. It is not comfortable for street but It has it's value, not waste of money!
