400 rwhp LS1  X package  (external bolt-ons)
The X package consists of a combination of components that work in harmony together with custom tuning to produce the absolute maximum power gains without the use of power adders and without heads and cam.  It was first developed on an '01 Z06 Corvette in 2001.  This car ran 11.44 @ 122 mph when most cars with heads and cam weren't running that well.  This was a daily driver with the stock gear and at full weight. The perfect combination of parts and precision tuning is the key to the X package and the X package is the key to getting the most power available from a daily driver.  Some people like not changing heads and cam because it allows them to maintain the factory warranty.  Some people just don't want the "race car" sound or give up the drivability that comes with a cam.  Some people just want to have as much power as a lot of head/cam packages are providing so that when they do heads and cam they will be well ahead of the game.  No matter what you want, the X package gives the absolute most power available from bolt-ons.  We have also been able to modify this package to work on  the LS1 F-bodies and C5 Corvettes. Check out the  LS1 F-body X package - 400 RWHP - naturally aspirated - without heads/cam.   The X packages are available only as in-house turnkey packages.

440+ rwhp LS1  X.5 package  (add Cam only)
The X.5 package is our cam only package.  We take the X package and add a custom ground Speed Engineering hydraulic cam.  RWHP will vary depending on how aggressive you choose to go.  Our original X package F-body with the addition of one of our smaller "stock gear" cams made 442 RWHP, that's a 42 RWHP gain over our all ready impressive X package.  With one of our huge cams you can see over 450 rwhp "cam only".
 

500+ rwhp LS1  XX package  (add ported heads)
The XX package consists of the X package with the addition of heads and cam.  This still uses the stock 346 cid short block.  Only the best heads and cam are used to obtain the 510 RWHP mark.  The cam is a custom grind Speed Engineering hydraulic design that is tailored to each customer's needs..  This cam is as daily driver friendly as any power cam on the market, if not more.  The heads are CNC ported and hand blended to provide the best power possible.
 

580+ rwhp LS1  XXX package  (add 427 shortblock)
The XXX package consists of the XX package with the addition of a 427 cid short block.  This combination gives incredible daily drivable power.  With a huge amount of area under the power curves the XXX package is simply an unbeatable naturally aspirated daily drivable combination.

 

400 rwhp LS6  ZX package (LS6 Z06's only)
The ZX package is a budget version of the X package for LS6 Z06's only. This combo gives incredible daily drivable power.  It is a GUARANTEED 400 RWHP naturally aspirated combination at a bargain price of $4000.00, that includes all parts, labor, and complete custom dyno tuning out the door.
