TESTIMONIALS:



Rich Koffel - Koffel’s Place (Michigan)
E/T’s CNC Sport Porting program took our mid-compression 471 ci package from 617 hp to 688 HP and
Torque from 582 to 674 lb/ft. Very Impressive!

Scott Koffel - Koffel’s Place (Ohio)
Our archives showed that the high compression 471 ci package did a best of 756 hp and 620 lb/ft. With
E/T’s CNC Sport Program, we got 794 HP and 650 lb/ft off the first engine build. Not too bad, hey!

Budget Sportsman Package w/CNC Ported B1 BS Cylinder Heads
Koffel’s Place(s) have been building many types of High Performance and Racing Engines for everything from Street to ProStock and Bracket Car to Marine over the last 25 years. “Our popular Mopar 471 cubic inch “Budget Sportsman” with B1 BS heads has been a real winning performance package for many years. We considered these changing times and understand that CNC Ported Cylinder Heads are here to stay. We tried the machining technology offered by the crew at E/T Performance for CNC porting our B1 BS heads and the dyno results say it all. We know a winner when we test one. There has been no disappointment with these CNC Ported B1 BS heads from E/T Performance that now allows us to offer this value added enhancement to our 471 Budget Sportsman’s package!”

Ted Pelech - Driver/Partner
Several #1 qualifing positions. Several Regional Event Wins. Several National Event Wins. Two-time
NMCA Super Modified Elapsed Time Record Holder. All of this happened after we bolted-on those
heads from E/T Performance. The biggest problem became how to hook-up that newly found power.

Short and Sweet – race winning performance!
The crew at E/T Performance looked at our existing heads and asked if we wanted to go faster? Dumb question, right! They agreed to engineer a cylinder head that would suit our 420 c.i. BB Chevy instead of handing us the “cookie cutter” head that fits all. What we bolted-on was quite simply, more airflow and more power in our useable RPM range than we had ever experienced before. Our initial performance results were outstanding. Once we got our set-up refined to this power increase, we have consistently run faster than ever. In fact, we have got this 3,100 lb. Camaro to go 182.21 mph and hit a low e/t of 7.623 sec., which of course allowed Pelech Bros. Racing to be a Two Time NMCA Super Mod Elapsed Time Record Holder. The technology from E/T Performance certainly helped our e/t performance!

Jeff Nowicki - General Manager, Specter Werkes
We strive for consistency with every engine package we offer. E/T suggested we try their
CNC Sport ported cylinder heads to get that power and repeatability. With their heads and
a cam change to accommodate the improved airflow, we achieved that consistency and
gained over 50 HP. Show me the downside!

Design, Passion and Performance – the working philosophy!
Like the Great Master Leonardo and his Mona Lisa, the Corvette specialists at Specter Werkes/Sports exhibit that same descriptive 3-point philosophy in every one of the automotive works of art they build and race. Unlike the one and only Mona Lisa, SWS produces the Matrix One, Matrix Two and the GTR 24/7 engine/car packages for their customers time and time again. Their naturally aspirated and super-charged Corvettes have been featured in numerous publications like Road & Track, Vette Magazine and Super Chevy just to name a few. “Good looking cars always get attention, great performing cars leave an indelible mark. Since we have used the technology from E/T Performance, it has been easy to achieve that goal of repeatable power and performance from our specialized engine packages leaving that indelible mark you can’t forget. Kind of like a moustache on the Mona Lisa.”

Kelley Longwish - General Manager, Wheel to Wheel
Our latest back-to-back dyno testing showed the CNC Ported LS-1 cylinder heads from
E/T Performance making more power than the CNC ported Z06 cylinder heads from other
vendors we have tried. That’s awesome!

Custom PPV’s – Mild to Wild!!
Wheel to Wheel is a prestigious builder of “ Personal Performance Vehicles”. Included among their impressive customer list are such notables as Jay Leno, Tim Allen and Greg “The Shark” Norman. They have produced everything from Nostalgic make-overs and Custom Corvettes to Custom H2 Hummers, Golf Carts and even all out Race Cars for drag and road course competition. The latest LS-engine from GM is the most often used powerplant for many of the W2W special PPV’s. That engine has created a big competition for producers of CNC ported cylinder heads to “strut their stuff” and W2W has tested them all. Our customers demand high quality and high performance. E/T Performance has delivered what we need to exceed those quality and performance demands. Give us a call to find the right Personal Performance Vehicle we can build to make your driving experience more notable!

We put those E/T Performance CNC ported heads with the 1.900” intake valves on our
V-95 Road Glide with a 203 HD cam and a header. Wow! Stood it straight up in 2nd and
3rd gear. I have never seen that before. Just unreal!

A Real American Performance Motorcycle Dealer
Wolverine Harley-Davidson has built one of the largest, most beautiful and well-equipped motorcycle dealerships anywhere in the country. They have taken this same pro-active approach to every facet of their operations, from the latest equip-ment used in the service department to the quality of suppliers of after-market parts they offer to the performance side of their business. E/T Performance is one of those suppliers. “They have taken the “factory” castings, for both Twin Cam and EVO style motors and have made CNC porting programs that out-perform every one of the other after-market brands we have tried. That includes those complete kits with pistons, cylinders, rods, cams, carbs, intakes, and ported heads. Our V95 kit with “stock” pistons, a 203 cam, header and E/T’s Twin Cam CNC Program with a 1.900” intake valve produced 93.4 HP @ 103.0 lb/ft. Using E/T’s program for the HD-SE factory casting with a 1.940” valve for the bigger 103 c.i. stroker motor with a 211 cam and 45 mm carb, we pulled an amazing 110.7 HP @ 118.7 lb/ft of torque! These are numbers measured at the rear wheel. On top of all that, we have built a lot of these packages and the power report off the dyno is so repeatedly predictable it seems we keep looking at the same result over and over! We have been told there is a 2.00” (intake valve) version available with a 2.02” and 2.08” full race versions in development. We are looking for that adventurous soul who wants us to build that Power Bike for him."
