Brenspeed?

[hottcobra]

wanting to know if anyone has or knows anyone that has had a custom tune done by Brenspeed in Indiana? thay said thay did an 05+ GT auto with kooks LTs, TCI convertor, ZEX 150hp shot, CAI, and a SCT custom tune and got 11.58 at 118MPH!!! this just sounds out of the box to me. what do you think?

[bullitt482]

Once you said converter, I'm pretty dam sure that was on slicks with some rear end work done. If it's not, that rear wouldn't last long on slicks.

If you are looking for a tune, I would NEVER mail order a tune. Two cars could have the exact same parts, but still require different tunes. They are kind of like fingerprints. If you are looking for a good respectable tuner, try southernspeed.com - Welcome!. He is in Tupelo mississippi. If you don't want to go that far, check out stanghi performance.

thay said it had stock wheel with ET streets. thay claim with 4.10s & stock rear end parts. I would never mail order the tune.

I would think they would run pretty close though. If you have 2 with all the same parts they shouldnt be that far off from each other. We do system matching at work all the time for customer's(Intel, AMD, TI) when diagnosing issue's for them. I can garuntee you they will never listen to that argument. I'm not necesasarily disputing your thoughts on mail order tune's just saying that matching fingerprints should give atleast close to the same result. If your racing mail order tune may not do the trick but for the everyday clunker it may be just what the doctor ordered. While I dont doubt I could find someone out here to tune my car for me, I dont know that it's absolutely necessary and Mississippi is a little far away

If you are putting a blower on a car and get the mail order tune , it would be close to what you would need compared to a 91 octane tune.It would save money on the dyno.

[PureVenom]

Mail order tunes can get close...with enough datalogging and emailing back and forth. However, unless you have a wideband setup, you will need to get on the dyno with each tune to check the A/F...which is going to run the cost up quick.

As far as every car is different, comparing cars to computers is like comparing apples to picture frames. I have an 03 cobra running 17 psi. A buddy of mine has an 03 cobra running 17 psi. His tune calls for 23* of timing and a good bit of fuel. Mine is calling for 20* of timing and less fuel. If you add fuel and/or timing to my car, it will start detonating and/or loses power. Take fuel and timing out of his tune, he loses power.

Cars are different just like was stated. While made of the same parts, they all react differently to the same changes.

I know every car is different and needs a diff. tune to reach peak performance. what I'm trying to find out is if you think that they can get a car to run that kind of times with the mods i stated. I'm new to the mustang world I'm used to the LS1 and I don't know how much you can get out of the tune.

I'd say it's definitely possible. With the CAI, tune, and longtubes, you're looking at just under (if not) 300 rwhp. That makes around 450 with the nitrous. Add two tablespoons of traction and a crisp shifting automatic, and you should be running mid 11s or better.

I'm not comparing cars to computers I'm comparing machines to machines. While not a direct comparison the basic prinicple is the same. If you have 2 cars or machines that are built the same they should perform close to the same or there is something else going on. A car is a machine using different systems, moving, and stationary parts to produce a certain result or product just as the equipment I work on. There are other factors than just parts. Were they made by the same MFG? Were the parts manufactured in the same lot? Have they been maintained the same? Granted the specs on a car are most likely a lot looser than a CVD reactor you should still see within a certain range the same level of performance. I'm not disputing the argument just saying that you have different applications for different situations. One way may be perfectly fine for Joe A. but not nearly enough for Joe B. or way to much for Joe C. No two cars or machines will ever react exactly the same but they should be within a certain band. The narrower the band the harder it is to match, maybe theres where I have a hard time because cars cost much less( 1 system=$2Mil avg vs 1 car=30K avg) and therefore most likely have looser MFG specs. I may go hunt down a place to have it done but if I dont need to for just everyday driving and some fun(drive to the coast) once in a while

[hottcobra]

well that just shows that the dibalo sport sucks when your not stock I have a ET of only 12.77

[hottcobra]

I mean it shows how much better a custom tune is

[JROC]

And how much better LS motors are.

No replacement for displacement.

[hottcobra]

well it is a little easier to test new tricks on GMs when you work for GM. (a little more resources at hand)

Did you screename get hacked or something, or have you lost it.

Thank you for the backup.




What bbunt said for the expected times .

In the words of the Geico caveman, "Yeah, I have a response. Ummmmm....... What?"

Computer manufacturer's precision and a car manufacturer's precision--FoMoCo's precision no less-- is like comparing a handgun shot by a blind guy and an ex Marine and saying it should be close.

What are you talking about, LS motors are better than any Ford motor ever, or they have the potential to be.

Ford = Better vehicles

GM = Better drivetrains.

Of course these are my opinions.

[bullitt482]

I agree actually about the LS motor being better, and cheaper. But as for GM's drivetrains, 9 times out of 10, you ask them what rear end they are using, and it's a Ford 9 inch.


I want an LS1...

[hottcobra]

well the 9in. is buillet proof. I think that GM makes a stonger auto trans.

Yeah, but it depends what you are comparing. I think the TH400 and the C6 are all but even on power handling capabilities, but the powerglides is the best. Only thing is though, it's not very streetable with two gears IMO.
