Frequently Asked Questions

Who developed the tune?
The tune was joint effort using CharlieX Monkey Tuna Reflash and our
in house Research and Development Team.

How much Boost pressure does the kit run?
This kit runs a base pressure of 7.45 psi.

What is the Pulley size?
All base kits are designed to use the 3.2 inch pulley

Is there a cooling fan on the intercooler?
The kit was designed without the need to use a fan but if you choose
one can be added to the kit at an additional cost.

Can I change out the pulleys for higher octane gas?
It is highly recommended not to change the pulley without having your
vehicle tuned for the added boost pressure. A lean condition can cause
knock events and lead to piston ring damage or worse complete engine
failure.

Is there a track tune?
We will be offering a higher peformance packages that will allow the
use of a smaller pulley for added boost pressure and higher power
output.

Who are you?
Vision Function is a sub division of TurboXS.

How many test miles have you had on your tune?
We have countless test miles on base kit as this products has been
under development for 2 years now. We have also have plans to run
the car at a few track days to shake out any problems we may run into while
developing a street car kit. Beta testers have been supplied a kit
throughout the US for street car testing as well.

Where can I get it installed?
You can have the kit installed at our Location in Gaithersburg, MD or
you can use one of our Approved Install Centers. throughout the US. It is highly
recommended to have a qualified shop install this kit or your warranty
coverage will be denied.

Does the clam need to come off for install?
No, removing the clam is not a necessity. I would probably recommend that you don't due to the additional rattles you are bound to make trying to get it back together.

Is it just a greddy kit?
No, this is not a Greddy Kit by any means. The only comparison the
kits have is that they use a MP62 Supercharger and that's where it
ends. We do not use the same SC cone configuration nor the same bypass valve placement.

Will there be a chargecooler upgrade?
We have had great luck with our standard air to air intercooler setup thus far. This is just a start.

Does the charcoal canister need to be moved?
Yes, it does need to be relocated we included a bracket to allow
secure fitment in a new location.

Is there a 06-07 kit?
Yes, we have a 06-07 kit.

Does it come with an A/F gauge?
The kit does not come with an A/F gauge but one can be added.

How much power?
See Performance Tab

What if I use 87oct gas?
It is very important not to use 87 octane in your car. You will be
required to run the highest octane level available to you. We have
maps for West Coast 91 octane and East Coast 93 octane please be
specific where you will be driving the car so we can supply you with
the proper fuel mapping for your ECU.

What about heat soak?
Heat soak is only an issue when a car is sitting still for prolonged
periods of time. Even with that being said, the ability to have an
intercooler made from aluminum and the porper fin density this allows
you to radiate heat greatly reducing heat soak conditions. The
advantages of an intercooler becomes multiplied with the slightest bit
of air flow over the fins. Exponentially reducing the air density
being injested into the engine. More Dense Air = More Power!

Do you sell the tuned ECU separately I have a BWR kit?
No!

Can I buy the manifolds separately?
Yes, we will have a Supercharger Intercooler Upgrade kit that will be available.

Is it the same supercharger as the Lotus S?
Yes, we use the Eaton MP62.

What are the discharge temps at sustained full boost?
On the dyno we saw a max of 230 degree Farenheit pre intercooler and
130 post intercooler at redline after many successive dyno pulls.
Keep in mind that the dyno is a worst case scenario with some of the
best fans available you can get a max 50 mph wind but we can top out
5th gear doing a power pull. The dyno is a less than ideal condition.

Will it work with UK fuel?
Yes, when ordering please specify your location so we can give you the
proper mapping to go along with your Supercharger Kit.

How come I haven't heard of Vision Function?
We are a new division of TurboXS, which you may or may not have heard
of in the past. TurboXS has been around since 1999.

Will it work with my CAI?
No, the Supercharger Kit includes our own Cold Air Intake System
designed to fit around our Intercooler.

Will it work with my headers?
Yes! But, it is recommend you have your vehicle custom tuned for any additional modification beyond the base kit.

Will this kit relocate my AC?
No, we do not move or alter your AC unit to install our kit.

Does the kit come with any type of Injection System?
No, we do not include a Alchohol, Water, etc. Injection Sytems. We do
offer the ability to use one of these types of systems as an optional
accessory.

Does this kit have a CARB E/O?
This kit is currently not CARB exempt. We are looking to go through
the carb exemption in the future.

How much does the Supercharger Kit weigh?
MP62 - 22.5 lbs.
Installation Parts & Accessories - 34 lbs.

Will I need to upgrade my clutch?
It is highly recommended that you purchase an upgraded clutch package
upon installation of this kit. We recommend the ACT Street Disk with a HD Pressure Plate.

Does this kit use a TMap after the intercooler?
No, the kit does not. It is simply not required. The use of a Mass Air
Flow Sensor gives you the best solution of metering air into your
engine as most of your fuel decisions are based upon the reading this
sensor relays back to the ecu. If inlet temperatures are high, less
air will be injested into the engine and less air flow will be read by
the Mass Air Flow sensor. If inlet temperatures are low, more air
will be injested and it will reflect in the Mass Air Flow sensor
voltage.

What are the demisions of the intercooler?
7.75 x 10 x 14
