Whipple question

[Whipple SC]

Currently putting 586 to the wheels

Our kit makes 650rwhp+ with our 7500rpm limit and 132mm TB so you should be in that range on 93 once you change TB and raise the limit.

How terrible that I will get to drive it back from North Carolina to Ohio only to put it away for 4 months. Guess I will just have to look sit in it and act like I am driving a 650rwhp monster

Yeah that sucks! I put mine up a month ago. No whipple for me until next November's sales. This is my first mustang and this is the first car that I have ever parked through the winter... Really bums me out. On a positive note, keeping the miles off!
Good luck

If you upgrade form stock throttle body to 132mm does the Whipple tune need to change.

Certainly does

I also just talked with someone a Whipple tech today. I was told the 132mm TB will offer better drivability over the stock throttle body. This is some what counterintuitive as usually larger throttle body is harder to drive and creates less tractability, more like on off switch. It was explained to me by whipple that more time was spent calibrating the large 132mm TB and therefore it drives better than the stock. Did I understand this correctly.

With the 132mm TB I was also told the larger 72 lb's are needed, but only for above 700 whp becuase at that power level the 58 lb injectors would be at 100% duty cycle. The 58's with the standard pulley at 640-650 whp would be around 92% duty cycle.

The stock TB settings are essentially the same using the stock TB, we didn't spend much time enhancing it. A little, but not a lot. The 132mm TB was flowed in the lab (giving highly accurate numbers) and we spent extensive time developing. By having accurate numbers, the PCM can the throttle very well. We worked on the pedal map to be somewhat aggressive, but not aggressive enough to be out of control. This in the end has better feel, control and also makes more power. Traction control, airflow limiting, etc are all based on throttle airflow therefore it is essential to have it correct. The day's of big throttles not being controllable is somewhat non-existent as each TB is pre-flowed to match stock standards at idle.

For fuel, the standard injectors are fine for the TB and 3.75" pulley with stock exhaust. With LT's, 3.625" pulley, etc and no BAP, the fuel psi falls drastically, causing the inj to go to 100%, but this is also a varying number as temp, humidity, fuel pump flow, voltage, baro all play a factor in what fuel is demanded. The higher flowing injectors gives us more margin and more potential even when the fuel pump flow doesn't keep up. We have safely made 800rwhp on a stock engine with our high flow injectors and stock pump (race gas).

Excellent and thanks you for your very detailed response, just what I was looking for.

I just upgraded to the 132mm TB from the stock TB a few weeks ago. I can't believe that I didn't do it sooner. With the 132mm TB, my car drives better than when I drove it off the dealers lot. I haven't had a chance to dyno my car again but you will be able to feel a big power difference. After 2500 my car screams!!!

Hey quick question @whipplesc

Just need to clearly some things was in a discussion with a friend today that has 2011 mustang & a 2.3l roush supercharger with 12.5 psi he has an Manuel that's putting down 540tq the discussion was that his car has more torque then mine I told him of course you have an maneul and I have an auto an my power will translate on the street and not on the dyno... The million dollar question is should I have more torque then him when I have a 2015 Mustangs 2.9l whipple supercharger with stock throttle body and it's an auto only on 9.5 psi putting down 586 rwhp and 454tq on a conservative tune with the rev limiter set to 6800

Well torque sounds right for only 9.5 and an auto, but you have 3psi less boost which is significant. An auto is 5-8% less rw than a manual on a typical chassis dyno, we use 15% loss for manual and 20% loss for auto. Pulley down and watch the torque increase.
