High Performance Engine Tuning Videos

We spend lots of time tuning cars at the V8 Speed & Resto Shop, and have learned a few things to help make dyno shop tuning sessions go smoothly.    If you need help with a custom tune for you car, be it fuel injected or carbureted, feel free to contact our shop at 314.783.8325 or at http://www.v8speedshop.com/tune and we’ll be happy to discuss having our technicians tune your car on the chassis dyno.    Read More to watch the videos for some tips from our crew!

Watch the video, guess the power of the 2006 Dodge Charger in the V8TV Forum, and you could win a Predator Hand Held Flash Tuner from DiabloSport! The DiabloSport Predator is a hand-held tuner that can help you modify the tune of late-model cars, and it can now tune the Mopar Hemi powered cars. We recently shot a dyno session on a 2006 Charger at Finish Line Performance. Watch the dyno pull video, then log in on the V8TV Forum to guess the power level it made and you can win your own Predator Tuner!

 

 We recently visited Finish Line Performance in Naperville, IL, to check out their open house and see some killer cars. Finish Line Performance is not only a very reputable 2 and 4-wheel dyno tuning facility, but they also build everything from custom mandrel-bent exhaust, turbo, and intake systems to complete engines and restorations. We take a look at their turbo Dodge Magnum and the LS2 427 cubic inch Solstice... it's an animal. The grand total for the open house was over 240 cars stopping by to check out the action. Between pulls on their 4-wheel dyno, Dan Bills gave us the skinny on his new Mustang race car as well.

 

Weve come to realize that the sum of parts on Mike Riochs 1995 Pontiac Trans Am LT1 350 convertible is in need of a performance tune to make them all play together nicely, so we headed out to Finish Line Performance to meet with Dan Bills to get the job done.

 

After the Dyno tuning was completed at Finish Line Performance, Nick Scavo and Mike Rioch headed out to the drag strip to shave a few tenths off the 1995 Trans Am's quarter mile time.

 

When it came time to plan the engine in our 1965 Chevelle project, we tossed around a couple ideas, but decided to modify the 350 that came with the car. It's a parts-store remanufactured 4-bolt 350 V8 with less than 10000 miles on it. The bottom end is ideal for a mild street engine, but we didn't like the crappy lo-performance cast iron heads and weak camshaft. So before we turned a single wrench, we turned to our handy copy of Dynomation engine simulation and dyno software to help us build a smooth 400 horsepower version of our engine. Dynomation helps you select cams, heads, compression ratios, exhaust.. all elements of engine design and then simulate dyno pulls and evaluate parts changes, all without buying a single part. It's a great way to hone-in on your ideal combination without having to spend extra money and time doing things twice.

 

1000 horsepower used to be a huge deal... you needed and extremely large displacement engine with and insane compression ratio and a monster power adder to pull it off. And when you did it, you basically had yourself a temperamental race-only motor that was only good for 1/4 mile passes. Not any more, thanks to combinations like this 540 cubic inch Chevy V8 built by Fast Times Motorworks.  

 

There are those who think the 2006 Ford GT is fast enough from the factory. Of course, we're firm believers in maximizing performance, so we installed an upgraded supercharger pulley, exhaust, and air filters to this modern supercar.

 

After logging some miles on our 1955 Thunderbird "CoyoTBird", we felt the car was running pretty well, but it suffered from a couple of things that we wanted to fix. First off, the car would backfire on deceleration, which we did not like but also signaled a problem. Secondly, the variable cam timing on the Ford 5.0 Coyote engine felt like it needed calibration. The car accelerated smoothly up to 4000 RPM, then the cam timing changed and it took off like a rocket. We wanted to see if that timing could be adjusted to bring on stronger acceleration at a lower RPM and not feel like such an on-off switch. We enlisted the help of the High Performance Racing program instructor Jason Gann at Ranken Technical College , as they have a chassis dyno and access to the latest SCT Performance tuning software to smooth out our 'Bird.
