Multiple Throttle Body / Turbo
I emailed this company (vision imports) and asked them about there turbo setup and see if they had anything and this is what they replied.
John,
We have a couple of different options for want to go
race with the lancer, of course you can do the turbo,
but I find that the mutiple Throttle bodies are much
more effective as they do not put constant stress on
the motor. Not to mention the price of a MTB system,
headers, fuel pressure regulater and everything you
need to run it, would still be way cheaper than a
turbo, and will create just a much power. Hope that
helps
Matt
I just wanted to know if this is ture and how does Multiple Throttle Body work?

could be true......
the RPW quad throttle body setup, with all the necessarry parts to run it, will be just about as much as RRM's
the claims they make from this throttle body are going to be tough to sustain though. 50% power increase could make it as effective as a turbo with less wear on your engine. However, if you wanted to go turbo route, you'd have to change out pistons, header, and almost anything else you did to the car to make room for turbo. something to keep in mind

if you think a throotlebody is gonna make as much power as a turbo...then I want some of what your smoking

we ALL want some of what I'm smoking, but there can be only one J-Roo.
seriously, for a turbo that only does 60-90whp I believe a quad throttle body with fuel regulating system, intake and exhaust should be just as much hp

If you can prove me wrong, hell i'll buy quad throttlebody setup.
I've only seen people use this on HIGHLY modified engines that already make a ****load of horse power. I highly doubt it would be any good for daily driving.

Just another update from the guy over there at vision imports.
I have a mirage 1.5. I Have MTB with haltech computer,
Port and polished head stage 2, headers,Fuel pressure
regulator, valve springs, cam shafts stage 2, cam
gears, pistons and conrods. stock hp is 92, my car is
currently putting out 167 hp, with more fine tuning on
the dyno to be done. RPW made all the products i have
on my car. It is farley easy to install and can be
fitted in around 1:30 - 2hrs. As far as pricing, just
make a list of parts you want and i will tell you what
the pricing will be. Thanks for your time

RPW Qaud & Twin Systems
I wanted to clarify this a little more as there is a lot of unknown info on qaud systems.
To start with I agree 100% with one of you there.
A qaud system on a stock motor will never produce a massive horsepower gain.
A lot of people think qauds create horsepower - wrong. Dead wrong.
Qauds and twin throttle body systems provide unlimited air flow to the motor in an unrestricted form. It is up to the motor to use that air, add fuel and then horsepowe is created. On a stock motor with stock cam it has no idea what to do with the extra air and hence minor gains only.
The min specs you need to run with a qaud system is
(A) RPW Race Designed 4 - 1 extractors
(B) Stage 2 camshaft
(C) 2 1/2" exhaust system
(D) Qaud system with FPR and programmable computer.
This setup would provide around a 30% gain over stock as a general rule of thumb. This is nothing to be sneezed at though as it would have a tremendously strong midrange and top end performance.
The twin throttle body system on the lancers would also require a computer, but would provide more midrange power with a little less top end performance.
To finish off - a well designed motor with qauds will basically produce teh same level of improvements as a turbocharged stock motor with 7 psi boost. The main difference is the qauds do not prematurely wear the motor out and are less tempermental and many other benefits.
Turbo's are great - RPW designed the first bolt on turbo kit for the Mirage in Australia which would also fit the Lancer vehicles so I am very aware of the benefits of at urbo and they are amazing to drive.
All I am saying is that people tend to go to extremes with qauds systems and they are a real race style application to the vehicle There main benefit is you can slowly build the car up to suit qauds and have a real road killer without worrying about detonating your motor to pieces.
The ideal qaud system is the above plus
(A) Ported and polished cylinder head
(B) Higher compression (Qauds love compression)
And then you are getting into the 50% power gains.
Anyway thats my $2.00 worth - I am more than happy to answer any questions no the qaud systems. But they are certainly not to be ignored as they aer very effective.

OK...I know this post has been six feet under for some time now, but I need info. I want to go completely NA with my car, but I do not want a quad. I've done a thourough search for the twin/dual throttle body and this is the one post that had the most info on the dual (I think). First, mitsiman, how's the r&d on the twin for the lancer coming along? Have you made any progress? Second, how much less difficult would it be to tune your car with a twin than a quad? Or would be about the same?

On the lancer to run the twin throttle body you will still need a programmable computer as the twin TB system will run two air cleaners which means that you would only be running a single MAF sensor on one side which would not work.
There is really not a lot of development to be done as the twin system is very straight forward and well proven on other cars in australia (Very commen on the Hyundai accent range and V8 cars).
The main thing is it will obviously increase the air flow into the motor tremendously in a staggered system so that the car does not lose the low end driveabiluty or torque until a present rpm point, then it gets a lot of air and makes a huge difference.

thanks for responding dave someone should have just done a SEARCH and read the million threads there are abut this!!! one is entitled 300hp and the other that is very usefull is called NA Stages do a seach next time and save people some trouble oorrr post this in the newbie forum if you ganna act like no one has heard of vision imports lmao
