Our pal Scott Clark is an EFI tuner that lays his hands and lap top on lots of different cars across the country. There are high performance street cars, drag cars, and land speed cars as well. The car featured in this video is an LSR machine that will be running at Bonneville this August. The car is a 1969 Dodge Charger Daytona that has been hand built by a group of extremely talented craftsmen. With a twin turbo 498ci Ray Barton Hemi providing the power, there are some very lofty expectations for this car. We’re not going to throw any stupid numbers out there, but this car is being built with the intention of laying waste to existing records by a wide margin. 300mph is one of the targets. We’re OK in saying that this is the wildest Dodge Charger Daytona in history.
What you’ll see in this video is some footage of the car in the shop and then the car making several dyno pulls with Scott Clark in the driver’s seat. He makes several pulls in the 2000-5000 RPM in order to tune the EFI in that range. Clark is tuning the VE tables and making sure the air fuel ratios are where he wants them. The dyno pulls were stopped when one of the guys saw a few drops of coolant hit the floor. As it turns out, a cap was loose, but it is certainly better to be safe than sorry.
Scott has not thrown a horsepower number at us from this engine, but is has to be in the range of 2,000-2,500 if we were guessing. We’ll keep you posted on their progress as the thrash for Bonneville 2012 reaches a fever pitch. For now, watch this video and gawk at the hairy chested awesomeness of this Charger Dayonta from hell!
Lee is the nicest guy in the world. His Daytona was stock-bodied for the longest: all steel. Not sure if that’s true anymore. In previous years @ Bonneville, he’d set a record and come back next year with a different combo and set a new record. If you ever meet him, you’ll be glad you did.
His other Daytona is still all steel (so is this new one). We had to replace the glass with Lexan in both cars per the new rules.
His N/A #1001 car broke eleven records at Bonneville and still holds a number of them. He plans on running that car in the future to hold onto as many of those records as possible.
The car in the video has been blown apart now for powdercoating and paint. Should be putting it back together in the next 6-8 weeks.
Wow..that car is so mean, the fuel pump alone can scare away a Doberman!
How many wires were bad? Definitely didn’t want to rev at WOT. Definitely impressive!!
It’s not supposed to rev at WOT, we had the dyno programmed to hold a fixed RPM. So we tell the dyno “lock at 5000rpm” and it adds braking force whenever we open the throttle. That’s how I load the engine to tune it (EFI). Notice that we started at 2500rpm, and moved up in roughly 500rpm increments until 5500rpm. At each RPM point we go from low throttle to WOT slowly and adjust the fuel for each RPM band.
That’s how you tune EFI on a chassis dyno. Most people are used to seeing WOT “pulls” but we weren’t interested in a HP number, we instead were more worried about making sure the engine had a good tune at all possible Load / RPM combinations. Hence, what you see here. The engine won’t rev because the dyno holds it back.
