Killer Ported MINI S head

These used Heads are reconditioned to Performance Specs by: "Thumper Performance of Orange Park"

Both the Intake and Exhaust Bowls have gone thru extensive Bowl re-work. Opening , smoothing, blending, modifying the Valve boss to direct and increase air flow, with attention to the short radius.
Intake Ports are matched to gasket size, Ported and smoothed into the Port to the bowl. Exhaust is Ported to gasket, then opened to allow more air flow from the Supercharger, with port blending and reshaping deep into the Bowl, and then Polished.
To maintain Port Velocity, the stock valve size is retained with a Performance valve job, and a " Flow" back cut on the valve to increase low lift flow at the valve and seat, for higher velocity and faster cylinder filling. This keeps the low and increases mid-power range!! ( no flat spots here !)
The Chambers have the "hot spots" blended to prevent detonation. Head is surfaced flat to insure seal, and will allow 18- 35 HP at the wheels, depending on mods!!
$1595.00 PAYPAL OK!! Price includes: Head/ Exhaust/ Intake/ Valve cover Gaskets !! FREE* Shipping !!

*** Refundable Core Fees of $600.00 will be ADDED to the cost and Happily REFUNDED when your Good core is recieved within 30 Days!

We took our head, and for testing we used cars off the streets.. guys like you and I , no tweeked out "test mules" with all the bells and whistles.

First is an 04 MCS, the usual bolt ons, Shark inj, cat back and 15% Pulley 2%, with a STOCK I/C, Cam, and Header . It pulled 222 Real WHP ( SAE 211 WHP) or 240.7 BHP!!

Another pull was on a 06 MCS, this MCS has a Schrick/ Header/ pulleys/GP tuning and cat back.. His was SAE 215 WHP or 245.1 BHP !!

We do have a HEAD on a MC, however his dyno results are NOT avaliable at this time. Some time the middle of this month! And yes, the head for the MC is worked and modified for the N/A engine .

Dyno sheets avaliable...

Have a JCW Head ? Send that and we will work it up to where you will have the better enhanced power and still have your own " JCW Head "!! Usual turn around is 10-14 days!!
