Well thought I would share this video with you guys too. We took Dads chevelle to the "Booze Brothers Racing" speedshop yesterday outside of Harrisburg to have them do some suspension stuff on his car. We ran into Brain at Mason Dixon a season ago after drooling over his 66 Chevelle that was pulling 1.2 60' times at 3200lbs, 496CI N/A motor. That day he was running 10.0s, but we learned that he got it down to 9.6s shooting for 9.4s!

Dad stopped in at their shop about 1 month ago and spoke with the manager, Charle Booze. He is world known for his having the worlds fastest street legal mustang! He cranks off 8.4s naturally aspirated, pulling near 1.1sec 60' times! He is sponsored by nearly EVERY major manufacturer of performance goods, and is a real good guy to talk to.

We took dads car their yesterday and spent till about 5:30pm messing on the dyno and BSing about how to make cars go fast. He said Dads car should be pulling down 9.4 ETs all day with the power we have compared to Brians.

We put the car on the dyno just for giggles and had some fun playing with it. I asked Charle what he thought of dynos and he said its a money maker and a decent, but not all said, tuning tool. It leaves a LOT to desire with what happens in real life. But they are fun to play with and see what a car can do, but can NEVER replace what real world results show. Guess I am not alone in my opinion...

At any rate, the afternoon was fun filled and we are pleased with the way the car performed. Here are the dyno runs.

This is Brians Chevelle and we hope to see Dads doing the same after some components are added.



Hope you like the videos - its always fun sharing

 

tuning tool. It leaves a LOT to desire with what happens in real life.

Wish more people understood that. Can't get the vids to load for some reason...

 

lol, man that thing pulls hard

 

Stout looking "67? Chevelle
In high school my brother and I had a 64 Malibu SS (pulled the 327/Glide out and put in a 454/turbo 350) a "70 Chevelle 454 SS Motion and a 69 Chevelle 396 SS. Wish we still had them we could buy a but ton of C4/C5s with the money. But I sure miss the big block torque.

 

Jesse,

Wow!

What were you guys expecting dyno wise? I've seen the other videos that you've posted of this car and wasn't expecting numbers this high. That's pretty awesome!

If you guys come back to Dragway 42, drop me a line and I'll meet up with you.

Yah after seeing some vettes at a local track with almost 490rwhp run 11.99 and anouther 12.5 at lower mph as mine little 358 RWHP car I give up on the dyno's. Plus the idea that they are hard on convertors..

 

What are these vids encoded with? Can't seem to get them to play on any of my machines

Ski,
Is it a 66 or 67 in your picture it looks like a 66 grill however, in the video it looks like a 67? It is a beautiful Chevelle.

agreed, you cant simulate the bow pressure effect on the car. That is unless your dyno is mounted in a wind tunnel. I believe as low as 120 mph there is about a half psi stackup at the nose of the vehicle. It can be even furthur amplified with a little application of bernoulli's principle (ram Air). 1 Psi at the big end can mean that car that pulled 13.1-1 a/f on the dyno at redline is running more like 13.8-13.9-1 and knocking like hell under the top end charge.

 

It really isn't arguing with Jesse because he simply doesn't listen to what others have to say. I'll just say my piece and be done with it. For basic tuning a dyno is a very valuable tool. Most people do not have a wide band O2 sensor in their cars so it can be very hard to get any reliable information about A/F at wide open throttle.

There is a very good argument in this thread made about the ram air effect that some cars might experience, therefore skewing the A/F ratio on the street as opposed to the dyno. This is a perfectly valid point but not all cars react the same way to this pressure, some might not be affected at all while others are impacted greatly. It is a great unknown that cannot be accounted for without either endless WOT tweaking at the track or a wide band O2 sensor at the track.

If you do a lot of mods and your car is running 15:1 or 9:1 the dyno gives you a very controlled environment to get it into the ballpark before you go and blow your car up on the track. Running lean for one dyno pull is a whole lot easier than running lean through all gears of a hard track pass. Dyno's do have a very good use. If you choose not to use them that is your choice but arguing that they have no use whatsoever is just plain ****.

 

This is a DVD format. If you can't view it, download a mpeg-2 decoder. I used http://www.download.com/Elecard-MPEG...ml?tag=lst-0-1

 

And besides that the afr will not change more than .2-.3 of a POINT hardly enough to throw you in a tail spin of destruction. Which is ALOT less than what the car will change AFR wize per gear.

How else can you find timing that makes more timing at at specific points like 4000 4500 5000 5300 rpm??

 

Charlie's a good dude... We actually do cryo-processing on some of his engine components for his NMCA Pro Stock Mustang; which are built in Arkansas by Jim Kuntz & Co. racing engines. Charlie KNOWS how to run the little tire cars; he and his brother stand a good chance of getting your dad's Chevelle way deep in the 9's where I've always believed it should be.

Thanks for the INFO!
Great Video, its going to be a thrill to drive that down the track Jesse!

 

Yes, thanks for that. I was able to get a viewer that played them. Odd, because I have practically a professional DVD studio that wouldn't open them...

Where are the pics of the sheets?

 

That didnt sound or pull like a motor of that HP should, IMHO. My 454 LS6 Chevelle, pulled 503 hp and it rapped up allot quicker than this Chevelle did. It had 3.55 gears and a 3000 rpm stall.
Maybe the video was decieveing.

 

I want to see Dyno sheets or is this

 

Nathan, before you start making rude comments, its probably best to read again what I wrote.

The comments I made about the dyno were not that of mine, but rather from a guy that is published in more magazines than you have probably read and holds SEVERAL world championships.

I have a realistic outlook when a car of mine goes on one - its merely a reference point, and needs to be validated with OTHER measurements. I view it no differently than if I would go to an autocross event for fun. I would have a blast doing it, but I might be the slowest car there. Not because I don't have the power, but rather cause I did not build the car with that intent.

As I have said before, if you built your car for dyno results then knock yourself out....Charlie doesn't have several world championships by racing on dynos, hence I believe that is why he answered my question the way he did.

My feeling is I could care less if people want to believe dyno number and that is it. My cars perform well on both track platforms and dyno in every case I have encountered. Therefore I have plenty of backing to ensure my power is there. It seems to me, that the only people that get super touchy about keeping the credentials of the dynos as something valid, are those that only have dyno number as credibility.

As for A/F ratios, one would be MUCH further ahead to go out and buy a WB02 sensor for their car for ENDLESS monitoring of fuel, rather than wasting the same amount of money on dyno pulls. I would rather trust a new sensor such as innovate or tech edge, than one that has been abused in a speed shop by guys running leaded gas over it or kicking it around on a shop floor. Hell you might be the one pulling onto their dyno right after Dad is done making 10 pulls with FULL Leaded Race gas.

------------------------

Sorry about the codec....not sure why it did that sorta getting familiar with the software version I have for capturing the videos.

Steve40th - not sure what to tell you....that is what Charlie said it made....but I take it with a grain of salt. I figured before going down there it would make between 720-750hp based on the weight and MPH at the track. It pretty consistantly runs 135+ MPH in 2000 DA weather and weighs in at around 3650-3700lbs. It takes a LOT of power to get a car that weights that much down the track at 135+ MPH.
I would bet your car if it weights about the same as Dads would only trap at about 123MPH. I am not knocking your setup, I am just saying that if your at about 500rwhp, that is where about you will be at. As you may or may not know, to gain 13MPH takes a LOT more power when already going bottom 10s.

Charlie called dad today and we are going to put a fuel cell in it and charle said it should EASILY go sub 9.5s! They played with the exhuast and other things and it picked up 10hp, and the DA was a little worse today. So on a better air day the exhaust will probably yield a little more. Again though the proof is in the pudding.

Jeb. We know the car should be going MUCH MUCH quicker ETs than its been going. For garsh sakes its been tuned back a little to 32* timing so it will consistantly hook better, but it usually turns 10.1s or 10.2s on very high 1.5 60' times! If they get it to pull 1.3 60' times we instantly will be around 9.7s, and you know it will probably yield more than .3 at the end ET if we gain that much in the 60' times. Hell my car is a 2.25 ratio. If I loose .1sec in the 60' it usually comes out to .225 slower overall. And if I gain .01 it usually alway will decrease the end ET by .0225. If that holds true which I doubt it will on dads a .3sec gain in the 60' would be .675sec quicker! Or 9.5 sec 1/4 mile times! That would be incredibly fast for that tank to be covering the 1/4 mile in! Charle told dad today on the phone that if he got it down in that range he would be nearing some records for his weight! Not sure which ones he is talking about, but it sounds cool.

again though the proof is in the pudding, we'll have to wait and see how the car works after we get it back.

 

I am with you...Dragway 42 when it cools down and lets see if we can make some killer runs this year.
