I am not really talking about peak power, but you see 260's 280's RWHP been advertise all the time, with those numbers people should be posting 12's all day long with a car that without a driver weights at 2890 lbs.
I am OLD drag racer, have not done it for 30 + years, but had a dragster and a few other drag cars.
Dyno's are strictly for tuning and not for bragging rights, and that is what happens time and time again on this and other boards.
Our car GXP bone stock with a good set of sticky tires will post 13.4's all day long.
Although this car was made for the race track and not for 1/4 mile strip and that is the way I like to use it, lots of curves .

Why Jack B?.
There has been 13.6 already posted bone stock with the Gs2 tires.

Does anyone out there in "dyno expert world" know why the automatics with exactly the same tune and mods on the exact same day and same machine with the same operator got results that were 40+ HP less? Is it just a function of the dynoing of automatics or is something else going on? Don't get me wrong my car is also "stupid fast" and I am very very happy. I also think that the 1/4 mile times will be close as soon as we can take them to the track. Just looking for an explanation.
It's called parasitic drivetrain loss. Automatics lose about 12-15% power to the rear wheels when compared to a manual. I don't have enough automotive knowledge to tell you why it loses 12-15%, but that's the reason. But a 40hp difference sounds a bit much.
Driver skill has a lot of effect on 1/4 mile time, reaction time and other things too. I think a 13.4 for an amateur is very good way to go Scott. He showed about 260 at the rear wheels on the dyno, and a ton of torque over 300 ft/lbs. I know most average drivers are doing in the low 14"s on stock GXP's. LV you continue to bash this tune and have yet to drive a car with it installed, I gotta ask why? I think most of us got it for the fun factor not to drag race, I don't intend to ever drag mine not why I did it, the extra torque really plants the tires in the curves, and if I want I can know drift the back end with enough power to control it.

Well not to be labor the point, but CAR#544 on my time slips is my brother in law, automatic GXP with the same tune and its just stomp the gas and go! So not much driver error there. Now the track is only 50ft above sea level, air is denser! LOL I am very happy with the performance of this tune. I only went to the track as a means of seeing the difference and to have some fun whomping stock mustang GT's.

You are beating him @ 60ft. and holding through the run. He trapped a little higher speed than you did, you may not be shifting at the right rpm through the run. You also need to practice, your brother in law is eating you on the tree. It is a good thing that auto is faster.

Oh I know I suck on take off on the tree, but I have no claim to be a dragger. It was just time trials at the track so the start the ET clock when you leave the line. I would always catch the Auto later in the run, you see that over the longer run the torque converter slippage verses stick shift with no slip. And you are right, the shift points need to be altered, but until I seen my dyno (the next day) Wasn't sure where to shift and would need to take time trying different things. I am sure somebody that has it all figured out will obtain a 13.2x sometime.

I am not bashing the tune, what I am talking about is the Dyno numbers.
If you all remember when there was only the N.A. one of the things I always postulated was a tune as the 1st thing you want to do to the car.
Same for the GXP, a tune is the HEART of getting your car to perform better.
I'd just wish we could quit posting this RWHP numbers from Dynos that must of the time do not mean much.
I rather see people spending their money 1st and foremost in a tune with the OEM parts that came with the car.
Once you have experience what a good tune brings to the table as far as performance then you can weigh in the other mods vs gain, just my
My point is people should not buy the Westers tune because of a DYNO number of X, they are going to buy it because is the best value for your money when it comes to getting better performance from your stock GXP.

I agree with out the tune, much of the other mods gaines are probably very small. I understand that DYNO's can vary, but you need some way to measure your gaines. We all went to the same dyno on the same day and did 6 cars. At least at that point we could see what the mod difference gave. Its all not an exact science, but at least we had data to use to compare and a ball park to evaulate where we were at. Anyway...I think the point of this thread was for people with the Wester Tune to give there opinion of the tune, and what better way then to just say its good and I like it, but to show hard numbers and facts of what gaines different people experianced. Then we all can share in the data and decide whats best to do to the car. Thats what I love about this forum, is the sharing of information, Ideas, good things, bad things. Bottom line, I am not going back to the stock tune...the fun factor won't let me!

As far as the dyno numbers I agree, I don't believe many of them. I know what the dyno is set for at this shop, and have found his numbers very conservative compared to others. He uses a 9% dynojet equalization most use 12 or 13 %. Deepbluegxp was dynoed not long ago on this same dyno and did a 236 the only mod he added was a tune and did a 280, the numbers don't mean much but the 44 rwhp gain does. That is all a dyno is good for. The dyno dynamics can be placed in "shoot out mode" so that numbers can be compared. This allows no intervention from the operator. We did the dyno runs, for fun, and to give us all a reference point. There was a lot of data that was collected from cars with different mods and it was sent to Westers so he can look at what different mods do to the AFR and other settings. He got HPT scans of every run, and snap sheets from the dyno itself. Dyno's are a very valuable tool in getting a tune dialed in.
