GFB Atomic Single Stage Boost Controller for Nissan Skyline R33 2.5 250HP Coupe

Product Description

The Atomic has earned a reputation as being one of the most reliable and effective manual boost controllers on the market, boasting a repeatable and steady boost curve, quick rise rate, and great bang-for-buck! The Atomic Boost Controller was tested on a MY02 Subaru WRX (whose only mods were a turbo-back exhaust) back-to-back with the factory controller. A base-line power run was performed with the factory boost control, and the boost level was measured at the same time. The Atomic was then installed and set to the same peak boost level of 0.9bar (13.2 psi) so that the spool-up time could be accurately compared before and after the installation.

Massive gains were noted low down in the rev range, as much as 18kW (23.4hp) AT THE WHEELS! This increase in power shows that the Atomic allows the boost to rise significantly earlier than the factory controller, which on the road represents much better acceleration from a whopping 1700RPM earlier in the rev range. All this WITHOUT exceeding the factory peak boost level, and for pocket-money price!

It is important to note that the MY01-02 (MY02-03 in the US, GDA chassis) model responds very well to this modification, because the factory boost mapping is very conservative in an attempt to keep the torque curve flat and the power delivery linear (which totally kills the feeling that you are driving a turbo!). Note of course that boost can be increased above the factory level for more power gains, but the purpose of this experiment was only to show the improved spool-up potential on this particular model WRX.

About Us

Larkspeed began trading in the early 1970's, starting with a small shop in Leeds, West Yorkshire, selling a relatively small range of performance and motorsport accessories such as Cibie Lights and Spax Shock Absorbers.

Since then we have grown to become one of the largest Performance and Styling Centres in the UK, with a huge and ever increasing website, and exporting to every corner of the globe.

However, our commitment to service and value has never changed. We have enjoyed such prolonged success because we deliver excellent customer service - day in, day out. And because we buy well, we can offer the best prices to our customers.

Our staff are the most knowledgeable and experienced in the UK. If you have any questions about any item we sell, please do not hesitate to contact us on 0113 2643231, or through the EBay messaging system.

Shipping

We ship worldwide. If the shipping charge is not automatically filled in for you, please contact us and we will happily quote you. Note that we cannot send items abroad using non tracked, uninsured mail any more, due to unacceptable level of losses. Quotes will therefore always be for an insured courier, or tracked post, depending on the weight and value of the item.

For items that are being sent within the UK via 2nd class post, please allow 3-5 days from the date of dispatch before contacting us. You will usually be advised when items have been dispatched via the EBay email service.

Please note that when working out how long it will take for items to arrive, you must add together the time to dispatch and the shipping time, as not all items can be dispatched the same day you order them. We will have entered an approximate dispatch time on each listing. EBay should work out the approximate date of receipt for you, based on both the dispatch time and the delivery time.

For all items that are sent via courier, you should be able to track your own parcel using the tracking number that we enter at the point of dispatch

Note that for items sent out via courier, all of the following post codes are classes as premium areas, and as such will generally incur a £20 courier charge, instead of the usual UK Mainland Charge.

Returns

If you would like to return an item that you have purchased from Larkspeed, you must contact us prior to sending the item back in order that we can authorise the return and advise the best address to return it to.

You have 14 days from the date of receipt in which to return your item. Goods must be returned in their original packaging, in perfect "as new" condition, in order to qualify for a refund.

If an item is faulty, or has been sent incorrectly by fault of Larkspeed, then we will reimburse the full price paid including any shipping. However if you have ordered the wrong part, or simply do not require the item any more, then you will be refunded minus our shipping charges, and minus any applicable handling charge.

Handling charges may apply on certain items which are made to order specially for you by our suppliers, such as Piper Exhausts and Clutches.
