All you guys talking about quads really need to remember that items such as a camshaft, new valve springs, fuel management, engine management, and timing adjustments must be made in order for the equipment to run properly. It's not a "bolt on". It requires some real tuning just like a turbo would.

 

Well according to Vision Imports (Matt) RPW quads don't really need all that unless you want more gains then things like a fpr,camshafts,valvesprings and ported heads come into play for people who want a alternative to a turbo the RPW quad comes with a Haltech ecu and all for 2100 or 2200 for the cold air version and with that you have more tuning leeway then a turbo kit with no ecu upgrade for 3500 or more dollars i see a quad as a alternative to NOS wich is a bad thing in the wrong hands.

All I'm saying is RPW's quad may not be everyones cup of tea but I will be mines in a few months a N/A HP is always more respected then turbo's just my opinion

 

well, quad throttle bodies without fuelmanagment is almost as equally dangerous as Nos in the wrong hands. The dual t.b. setup is probably a little easier to get by with just a new ECU.

 

I'm not knocking on the Quads. You better get a second car.

Locally, a friend of mine is the 1st mirage in the US to use the Quad . . . In the final stages of tuning. Guess what, it has taken him close to 2 yrs, including his project 92 Maxima and 1g GSX.

There are a lot of tuning. A lot!

W/ Quads, you will have to replace the ecu since it doesn't use MAF. A stand alone ecu will have to be used too!

 

It comes with brand new HAltech ECU If your friend did not take that into consideration then it serves him right for taking 2 years you need to get total project time/cost and multiply it times the X factor of things going wrong I am fortunate to have patience with this unorthodox mod as I stated before Quads are not for everyone

 

ok its stupid, but:

1) What is a Quad throttle Body

2) What does it do

3) y cant it use an MAS

 

The latest performance development is the Quad Throttle body which has basically been taken straight from the Super Touring Race car to your road car. If your looking for serious power gains the quad would have to be one of the best modifications you could ever make. With a performance gain of around 40 - 50%, which is extremely good bolt on power gain for a naturally aspirated engine, you are way in front when you compare the price to a Turbocharger and the additional engine modifications that need go with it.
The Quad system comes complete with a fully programmable computer so that the engine can be tuned for maximum performance. The other advantage of having a programmable computer is that the car can be tuned to suit any modification that you make at any time. The assembly is handmade from billet aluminium and incorporates a throttle position sensor for accurate fuel and ignition control.
The induction noise is unbelievable - no kidding it sounds just like a Super touring car. (Utilizing individual air filters instead of carbon fiber air box and single ram pod filter assembly)


Together with a modified camshaft, exhaust, extractors and ported heads you could expect up to a 70% increase in horsepower


. As an example, the development car which is a 1.5L SOHC Excel (12 valve) should produce around 115 kw (153 hp) to 125 kw (166 hp) which is up from standard 65 kw (87 hp). Initial Dyno runs have resulted in 112 kw (150 hp) with continued fine tuning to follow.


This kit can come supplied with either a carbon fiber air box or K&N Large filter, throttle bodies and intake manifold. We can also supply a programmable computer additionally if you don't already have one. It is not really possible to run the vehicle without some form of computer modifications


We supply and recommend the Haltech E6K system. No other system provides as much value for money nor the superior programming ability.

 

Now it comes with a diffrent HALTECH not the E6k

 

so if i understand its a seriously tuned throttle body?? Is alot larger than stock or what?? How is it able to produce that kind of results??

 

no it has 4 butterflies instead of 1 will post a pic in a sec
thx lancer560

 

it's like having four 65 mm tb with four cold air intake.

 

actually they are 40mm x 4 =160mm total

 

WOW!!!!!!

 

oh, ok thanx clears up alot. BTW it looks beautiful, guess im gonna have to save

 

The qauds will work with a standard engine but not as well as it would with other mods. We do recomend it be the last mod done to the car.

Qauds love compression and RPW has for the mirage platform 11.5 : 1 CR pistons which sends a car with qauds ballistic. But as a min spec qauds want a stage 2 cam, tuned length 4-1 extractors (Very important) and of course the Haltech.

We have always used the haltech system but can use either a Haltech E6H system or E6K depending upon the customers requirements.

NOS can be used with great success on qauds especially an individual runner with wet nitrous.

In fact we have just started building a 4G93 1.8 engine for VIsion Imports which is getting

10.5 : 1 CR Pistons
Haltech E6K sysmste
RPW new spec (Still in design) Race Qauds (Shorter runners but more direct air flow)
Stage 3 camshaft, full ported head
RPW Extractors
Modified bottem end, bored and stroked to 1.9 litres
Wet NOS system with individual runners.
Also with soon to be released RPW Mitsubishi specific surge tanks which will be a bolt in item and look origonal.


No you do not have to touch the bottem end of your motor for more strenght for qauds other than a recomedned piston upgrade for more compression, more strength if you plan on running NOS

The Haltech compatibility problems with the 2.0 lancer are being solved as we speak by Haltech direct who are making the appropiate modifications / amendements to make teh compatibility issue disapear.
