TurboXS Dyno Exhaust Dyno Plots
Here are some dyno plots from our exhaust testing. These show the middle runs with and without our exhaust components installed. Nathan will post more plots next week showing the high and low runs when he returns from LA.
Stock run vs. TXS Catback Exhaust:
Stock run vs. TXS Catback and Catless Race Pipe:
We only have this one crappy pic of the CBE to show you right now. We'll have better ones next week:
Thanks,
Mark

Exhaust looks fine, would like to see a side pic if possible of the tips. Or even better, mounted on the car and a back picture of the car.
The Dyno though... hmmm....

Remember guys this isn't a dynojet or a mustang dyno its a dynapack,
Measuring your horsepower depends on whose yardstick you use.
Mustang dyno's get the lowest numbers 140-160 Dynojets are more optimisitic 170-189 and since this is the first dynapack on the forum that i know of i really can't do a comparison, but it would seem to be even more optimisitic than dynojets. ITS JUST A NUMBER not anyway a real world value, tune tool not true statement of what your car puts to the ground
Nathan/Mark do you have a machine to meaure AFR as well?

I do not believe in the whole "limp mode" hub-bub and even if it does exist, which it doesn't, the way it would be doing it is by retarding timing and it would be retarding timing for when you get a baseline and when you put the new exhaust or whatever comparative part so its a constant so IT DOESN'T MATTER, mainly because it doesn't exist!
Good luck on your runs, if they can fit me on thursday i'll see you there.

Stockish RX8 (it did have a REVi intake) made 170-180whp. The graph shows the middle of 6 stock runs where it made 177whp. With the catback and catless race pipe installed it made 199-205whp. Middle run was 201whp.

In any case, however, I agree that a dyno is a tuning tool and a tool for measuring relative whp gains. Do not try to compare our absolute numbers to anyone elses. However, you can compare them to other cars on this dyno.
We not only have a wideband, but we make them. We did not hook it up for any of this testing, however. Frankly, until we have a device to control fuelling, there's not a lot of point in measuring what it is. The car was running rich as hell though as evidenced by the backfiring and occasional flame out the tailpipes. We can hook one up on your car if you like when you come in next week.

it's not really necessary though since the pipe size is staying the same, which cuts the flow in half for each leg, I'm willing to bet that a straight tee in this location won't show any measurable difference on the dyno

EDIT: Keep in mind the reduction of about 21bs off the stock system

Im just curious to see how much the lamdas will get much leaner with the addtion of a racepipe. If its not to much trouble to take the stock one out of the CAT then lets do it, i know that the threads in there might be pretty difficult to get out.
