Dynoed the 300c srt8 today

[Gymratt]

Dynoed the srt8 300 today at wbd. I was using my diablo handheld with the 93 cai tune. First pull was 368@5400 361tq with a superfat 10.7af. My wot fuel was 8.5, 15.5, 14.5 with my custom street tune lol.
I had been playing around the last few weeks on the street trying to adjust fuel and spark after datalogging. With no wideband it's damn difficult.

Next pull with 8.5, 10.5, 9.5 fuel netted 388.6hp@5500 & 378.5tq. St kr was only 2.5* for a split second or 2 and a af of 11.6ish.
Third pull with 8.5, 7.5, 6.5 was 405hp@5874 381.6tq with max St kr of 3.0 and a af just under 12. I did 3 more pulls with -1* spark from 5-7k and slightly leaner at 12.1 and 12.2af's before i left. I couldn't do any better than the 405 pull on those last three pulls.

For just a afe cai, tune, 9db reso delete I am surprised by the numbers. ambient was 86*, ect 190-201. I was pressed for time so no cool downs between pulls or ice tricks etc. It's still pretty fat so there's more hp on the table. The guys at wbd couldn't be any cooler. Thanks a lot wbd!
Ps..For those unfamiliar with wbd, they use a mustang dyno with innovate wb

those are nice numbers, but just numbers. But a great example of how any owner can use the Diablo to help his power.

And there's a reason these cars are set up pig rich from the factory. Better log that thing carefully on the street.

Let's see that girl run at the strip!

Thanks, I am looking forward to running at he track in a little cooler air. I have never run in a da less than 2200+ so going in september to try and join the 12 sec club

they are only numbers, but at least you know where you started at and where you ended up...which is AHEAD!

thanks, thats the best I've done, so with good gas, good weather and all the cards right, it may keep it's power.

i run non-ethanol gas, so im pretty sure she's running strong almost all the time.

what's impressive to me is how much difference those small predator changes made...makes me want to run out tomorrow and get a CMR tune. I've been holding off until I can get a cam.

I too was shocked by the gains with such small changes in fuel enrichment. I'm thinking my tq
#'s would be better had I remembered to turn ESP off before all the runs. Thinking tm may be reason for the lower torque. I totally spaced out on the ESP part.
