ENGINEERING AND DESIGN SERVICES AVAILABLE DIRECTLY TO YOU!

Over the last 30 years the one thing that never fails to surprise us in the push to create a better race engine is how often valvetrain design is neglected. When we first started in 1980, it was an accomplishment to get a Pro Stock engine to survive at 8500 rpm all the way through the traps. Back then an extreme engine combination would consist of .800" of valve lift and 900 lbs of open spring pressure. Today, you'll find that those 8500 rpm redlines are now 10,500, .800" lift is now 1.100" and 900 lbs of open spring pressure is more like 1200 lbs. With the technological advancements in machining and engineering, what was once extreme has become common place and yet somehow the valvetrain has for the most part been ignored. This is the result of reactive, not proactive valvetrain engineering. Designs and modifications without the foresight to see the road ahead. The JESEL Custom Shop was created to be a clean slate. To fix what has been neglected, to think ahead, to be proactive.

Our technological and engineering abilities are at your service and available to both racers and engine builders. Contact us today to see how we can help you stay ahead of the competition this season, and the next 30 seasons. customshop@jesel.com

NEW 24° BIG BLOCK CHEVY


NHRA Super Stock customers running BB Chevy heads who complained about changing valve springs on a weekly basis switched over to our solid bar system and never complained about losing springs again. They also picked up a couple hundred rpm along the way! Engine builders ripping spread-port exhaust stands off heads cured their headaches with our extreme-duty one piece mounting system.



NEW B.A.E. STAGE VI

 

Here's the fix for the traditional antiquated Alcohol Hemi® rocker system, a clean slate design featuring individually mounted rockers with a secure and rigid mounting plate. A rocker system that is easily serviceable between the hectic elimination rounds yet durable enough to see you through to the points championship. Currently in development and with an anticipated release for the 2010 season, the addition of this kit to our lineup means that JESEL will have rocker arm superiority in all classes ranging from Top Fuel to Top Dragster.

COMPLETE LS-SERIES REDESIGN. CHEVY LS-7 (LS1 - LS3 - LS6 - LSX - L92)

 

A number of JESEL customers running GM LS based heads designed for 1.200" diameter beehive springs and .500" valve lift want to run close to an inch of lift with a 1.650" spring. This is great to see except for one thing, they're running LS heads. A challenge like this is what the JESEL Custom Shop was created for and although it wasn't easy, the dyno results speak for themselves.
