hi guys new member and just thought i would share this info that i got from Alert Motorsports in NZ. The guy name is Armand...anyway, i have been doing my research to find out what mods i can do for my new 206 gti 180 that i bought (love it by the way ) and i was interested in the air induction and throttle body kit...and when i email Alert they sent me this really informed tech report that you will find (all gti 180 owners) is quite suprising. i want to say thanks for having me and will post tech and pics as i acquire them...here is the email that Armand sent me...
Good question on the induction kit as we have done a lot of research and testing here in New Zealand on the 206 GTI-180.
The reply may be lenghty, but it warrants it as the system is quite well engineered:
We have tested the VFC263 Viper Cold Air Induction System on a demo-car, and found the original airbox to be more effective (!) with the addition of the PP1585 Panel Filter.
It has a rather complicated system, obviously well engineered by the people at Peugeot, with regulated Twin Air Intakes before the Airbox itself.
A vacuum actuator on the seconday intake pipe (operated by a solenoid and vacuum booster) opens the valve when required and lets more air in,.
The principle behind this is an old one: a slightly Restrictive Airflow can produce better torque with a certain plenum chamber set-up. However, as the rpm is increased, so is the Air-requirement. To lesson the increase in negative pressure and balance this, the computer regulates the second intake to optimise the airflow/pressure before the filter. Very clever though: The pressure is sensed from the actual Plenum Chamber itself, to lesson the effect of the Air Cleaner Element status.
Although there was a gain in Torque, and 0-100 Km/Hr was 0.9 seconds better than original when using the VFC263, the best gain in Torque and BHP was made by replacing the ORIGINAL filter Element for a Pipercross Vortex Foam Panel Filter (Part No: PP1585).
This bettered the 0-100 run by 1.2 seconds, and found an overall increase of 6% in BHP.
Changing the Throttle body for a larger size butterfly type, would merely increase induction noise levels, not the actual performance.
The only other option for greater power from this well-engineered system, would be by adding a Twin Helical Screw SuperCharger, with intercooled heatexchanger.
The PP1585 is available ex our stock at $ 100.00 including GST.
We also have the VFC263 in stock at a reduced price of $ 500.00 including GST.
(Both prices exclude Freight)
if you guys get any infor on any more of this kind of tech stuff, let us all know
