Thank You and we use a AWD Mustang Dyno. 500SE

 

Never a problem.
We spent a great deal of time experimenting with various setups. First came cam profile. We found out in Oct 2007 that we had come up with a good camshaft and thru the past year we refined it for various applications. Then we refined the turbo selection to fit our street car needs and still be able to exploit it on the track.
The most important component was getting all this to work with some ideas we had and shared with HeadGames Motorworks. Dave and I discussed what we wanted from him and he came up with a great gameplan.
Basically increasing the efficiency of the system by utilizing as much of the volumetric capacity of the engine as possible. being able to "control" flame speed and propagation a bit better, and keeping cylinder to cylinder chamber variances to a minimum. This helped us in other areas such as fueling. The increase in efficiency led to better Brake Specific Fuel Consumption Rates, and better cylinder pressure and temperature control. This all had to work with a cam profile that we designed to work for maximum air flow on two profiles. One on the stock base circle to keep costs down and cores available. And second on billets that could be built to the customers expectations. We have been R&Ding alot of this for some time now on the track only... Its just time to make it available to those on the street.

 

Great work DTM

 

Thanks once again for the explanation!

I was under the impression that it was one of their newer CNC heads but now i know it's not

 

Congrats on the time! awesome runs!

 

Nory, the reason why Im running the c16 is to prevent detinatation. Im still on my pump gas tune. If you were down here it would be a different story, but Nick told me how much of a monster your car is. I honestly dont remember where he said you went, but if you do get a chance you should come back down here and roll to the track with us to see whats up with the questions you had in my other post.

 

nice job guvna

 

Nory, the reason why Im running the c16 is to prevent detinatation cuz its so cold outside. Im still on my pump gas tune. If you were down here it would be a different story, but Nick told me how much of a monster your car is.

I'm down in Bogota, Colombia. I miss my car, It's in my brother's garage in Waco, TX. The car is a beast, the only thing I am going to have done after I get back is larger cams and a dual pump set up. Then I'll have Nick retune it. I just want the same power I have now at 5lbs less :-)

 

Sick Nicely done man I want a 10 sec car one day just like Paul Walker

 

now throw some slicks on her and lets see what happens

 

Unfortunately Ill have to wait till next season for the slicks. Im kinda broke. And my tcase wouldnt last the launch.

 

Awesome result!

Not a pump gas map if it needs race fuel though. I mean if my car was mapped on pump, and my tuner told me before going to the track I better pour a couple gallons of C16 in just in case, I would be like, uhhm, WTF? A 1/4 mile run is not hard on an engine at all so why need C16?

But anyways that is nutz... 10 gallons in the tank, heavy car, low'ish boost, pump gas tune with slow burning race fuel, crappy 60 ft, and a 10.67?

Hell, with race fuel / map, more boost, and a decent 60 ft you will make the Bad Bish look slow for what it did with a 35R (9.5 or so I think).

 

Let me respond to both of these if possible. I was very busy this past weekend and did not see these responses in two different threads. Sorry.

Crcain, Your first paragraph is flawed in many ways. But I think that you read into the story in a different way. Easily understandable. Sometimes people don't come across well in internet dialogue sessions.
His car was tuned on pump gas. End of story. I'm not sure how you came to the conclusion that I tuned the car any differently but I can assure you I am positive to the nature of the base map.
Now the reason "his tuner" told him to put c16 in the tank is because of many variables that I have already explained. But I may need to clarify yet again.
We tuned the car to 23 psi. It was immediately apparent he did not have enough fuel capacity in the system to support any increase in boost. At least not at a point that I would feel comfortable with him running on Pump gas.
The weather at the time was pretty good but ambient temps were in the 50's that morning. Now to be on the side of safety, I recommended he run a mixture of c16 because of the inherent nature of Hallman BC's to spike in the higher gears and hold in 4rth. Running a bit of race fuel helps keep him in a margin that I feel comfortable in considering AFR will get a bit richer on the scale with c16 introduced to the equation. This allows him to run back to back runs all day long.
Now if for some reason you think drag racing does not stress the engine or any component on the car for that matter, then you have not gone fast enough to break anything yet. Kudos to you for building a great machine!
Now one more thing to concider, "race fuel" does not burn slower. Im not sure why that myth still exists, but it is not true and has nothing to do with this topic.

Nory, good to hear from you again man, I hope to see you soon, keep your hed up out there.
On to your post, I think I have answered the race gas question pretty well thus far. If need be I can go into it more if you like. Let me know.

In your particular case, you have a much different setup. First of all with your turbo. You have a bit more compressor than Anthony and require a bit more rpm to manage it. He was revving out to 8k on every shift and holding out 4rth to 8600. That makes a HUGE difference because he was staying in the powerband longer.
Secondly, your tune was extremely conservative, for two reasons. One for the fact that we knew your were going away and I didn't want your brother having too much fun, LOL J/k. I wanted your to enjoy your car for once. You have had a rough history with it. Secondly your induction system is a bit different as well.
We have been able to run quite a bit more efficiently with our IC over the one on your car. He has a different cam combination and turbo manifold design.
Not to take anything away from your DNP setup, But there are stark differences in both of your setups. He is able to run alot more efficiently in both the cold and hot sides of the system.
Either way, when you get back into town we will go over and get you up to speed so that you are in the same boat. You have all the tools in the engine to do it, we just need some little changes to the induction system.
Talk to you soon.

 

Hey Nick,
Thanks for the explanation. Let me know what cams and anything else I need. I am starting to stock up slowly. :-)
