DYNO DAY at DC PERFORMANCE - Saturday, July 10, 2010

Banzai Ben · July 15, 2010, 11:19:53 AM

Hey Art,
It only had 456 at the wheels >o. Dan C. said the loose converter, auto trans and huge rear end and tires can soak up 30% or more of the power. I guess I should have run it with the nitrous! Seat of the pants feel is very good though, it breaks those tires loose at will and pulls strong. The car is lighter than my Viper so I think the true test would be to time it at the drags.

Ben -
It looked like the Camaro was running pretty rich (I assume because of your intent to use nitrous with it). Leaning it out a bit would have picked you up a decent amount of power, but don't run it leaner with the nitrous.

Banzai Ben · July 16, 2010, 03:21:22 PM

Hey Matt,
Yes, Dan said it was running rich but I guess it's safer that way, especially with the nitrous, like you said.
I was surprised at how much driveline loss I got because the engine builder showed me dyno numbers of 650 hp for the motor.

Yes, with a carb setup you need to run it rich for when you use the nitrous. Did the engine builder dyno it with a leaner tune to the carb? As far as the losses, keep in mind that automatics have alot of parasitic loss in them. I suspect you're losing the greatest percentage in the tranny.

Camaro sounded good.

Like Matt says, Auto trans with high stall converters don't dyno very well.

I'll bet the car runs 10's with a decent 60' time.

I told the engine builder it was rich and he said the same thing, it was safer but that I could bring the car back if I wanted more tuning. It feels really fast so I may not.
I'd be happy if it ran 10's. It would definitely need some slicks on it though.

MoparMan · July 17, 2010, 04:40:35 PM

Yeah, the auto is hurting the dyno numbers but once you get dialed in on a launch RPM the auto will be a huge asset in bracket racing.

NK BREKR · July 17, 2010, 04:57:33 PM

Cheer up Ben, the Camaro is one nasty car and as Dan and Matt mentioned the car will probably run 10s. We might have to start looking for a new nickname for you since you're already fast on the roadcourse and now you have a fast drag car, I see you're aiming for Hugh "Mr.202" Hoard >w

Banzai Ben · July 17, 2010, 05:11:23 PM

Hey Matt, sounds like you've done some drag racing in the past. What car were you running?

Thanks Art. The Camaro is plenty fast enough for me so I have no intention of trying to get to Hugh's level.

MoparMan · July 17, 2010, 06:37:21 PM

I've done a bit of amateur bracket racing in a Dakota R/T I had as well as my 2000 GTS and my 2006 SRT-10. Long ago, I restored a '69 Charger R/T SE that I wanted to run occasionally, but it never worked out and I sold it to get the 2000 GTS. However, I haven't dragged anything that can run the ETs and trap speeds of your Camaro.

I've had a couple of guys ask about doing a "Day at the Drags".

Maybe we could set something up this winter with DC at Fontana? Any interest?

On the drag front, I've run 10's with the Beast on drag radials by just slipping the clutch, rolling into the throttle and "granny shifting". Hard to keep from spinning.

No 9's yet, afraid of breaking things.

Pretty sure the run I had against the ZR1 in my ACR (for the TV show) would've been high 10's in the 1/4. I ran 7.35 @ 108 mph in the 1/8 mile and as you all know, the while the Viper isn't easy to launch, it finishes very strong in the 1/4.

Dan - Are you thinking about a track rental at Fontana? I'd definitely be in.

Banzai Ben · July 20, 2010, 06:27:19 AM

I'm in too.
Thanks

ViperX · July 20, 2010, 06:00:38 PM

Matt and Ben,

Yes. I think we could get DC to come out and bring some cars and if we could get at least 10 cars (hopefully more), the cost per person wouldn't be too high.

It would have to be on a weekday to get the best rate and cooler weather works better for our cars - and most of us!

Wouldn't care to do the Saturday or Sunday deal where you sit in line most of the day waiting to run and get only one or two runs.

Hey Lance,

What do you think?

Any other interest?

Dan

PCH VIPER · July 20, 2010, 06:42:37 PM

I agree with the weekday deal. Last time we went on the weekend, it was pretty miserable....and I was there as a spectator! Took forever for the Vipers to get cycled thru.

DC Perf, could probably rally a bunch of the Viper truck guys to come out too. Maybe a little friendly competition could be set up with the VCTOA group?
