or, at least as much of the tune we can hold back on a chassis dyno. We made it to 1440 ft-lbs at the wheel during VE map tuning before spinning tires.
This is Lee Sicilio's new car, starting off in A/BGALT at speedweek this year. Engine is a Ray Barton 498cid Hemi turbocharged with a pair of ProMod 91mm units from Precision. Ryan Fain at Brink Racecraft built the entire car.
Anyways, here's a little video from the dyno last weekend:

Bad-azz. :evil:

Sounds stout to me.

Wow, huge turbos. Looks great. What was the horsepower you saw on the dyno?
-
That dog knows when to skidaddle....that's a brutal car, love the intake ,cooler and exhaust work........

Don,
most of the session was used for building good Fuel and Timing maps at part throttle. During one test at 5100rpm and 6.7psi of boost the dyno recorded 1440 ft-lbs at the wheel. Later in the session we tried to make Ramp pulls (what you see more typically in dyno videos, a WOT pull over a set RPM range), but the tires spun on the rollers at 800whp which happens before the engine even makes boost.

Cant wait to see it, Bad arse :cheers: :cheers:

That sounds nasty! I dig the way you have the turbos mounted up front. Gonna tuck right up under the nose, right?

Lee that car looks great good luck at Speedweek. Gary

And yes, I know, the exhaust exits are not optimal for the application, but this year there's simply no room in or under the car to route them out the back. (been told that a few times already) :-)

D A M N that thing is gorgeous.

Wait until you guys see the interior fab. This car is awesome.

I think they look perfect! wink
Fabulous work!

Lee's other car is awsome and this one is even more awsome. He is going to have a ball with it at SW. Scott will give him a great tune that will be driveable.

Dieselgeek:
My budy owns a superflow dyno and we would like to know what system was used to capture that video with the dyno guages superimposed on the screen? Can you PM with contact info for the chassis dyno the Lee used? We would like to see if we could add that video to the dyno here in Tampa, FL
Thanks,
Bill

Bill,
The data does not come from the dyno - it comes from our EFI system (in this case, a Megasquirt-3x). I took a standard datalog, which is a .CSV file (comma separated - you can open it with Microsoft Excel or other spreadsheet programs), and I used a program called RaceRender to sync up the data with the video I took on a standard HD video camera.
Then RaceRender lets you define as many gauges as you have variables in your datalog. The trick for the megasquirt is, you have to edit the log files a little bit by deleting one of the top two rows of data, then saving it and opening in Race Render.
Whtaever system you use needs to have a "Time" or "Seconds" field in the data also, in order to keep it sync'd to the video. It's somewhat of a steep learning curve, took me about 3-4 hours of fiddling before I got it right. but once it's all sync'd up, you can use any field you like or calculate new fields. I have versions of video from that weekend that include Horsepower gauges (based off fuel burn and measured exhaust O2).
RaceRender can be found here, I think it was $45 for the pro version? http://www.racerender.com/RR2/Features.html (http://www.racerender.com/RR2/Features.html)
I plan on adding the same data overlays to our in-car footage from Speedweek this season.
Hope that helps,

Thanks Scott:
I will pass that info along to Matt. When I showed him the viideo he was impressed. He is a former Import Champion and a big turbo guy so he loved the motor but wanted to have a video package to offer his dyno customers.
Thanks again,
Bill
