Disappointed with Whipple Stage 2

[schmeky]

Welcome to the myth that has been perpetuated enumerable times in the Mustang/Whipple community. I felt exactly like you do after I had some drive time with the Whipple.

"Makes tons of torque at low rpm".

Actually, no it does not. And please, spare me the dyno charts.

I have a Whipple on my 2024. It drives like stock. Only when you hit it hard does it start making boost, then the A10 (assuming you have the A10) downshifts and puts you in boost anyway.

I can't tell the difference in "low-end" power between my Procharged 2018 and Whippled 2024.

I have no beef with the Whipple, but in hindsight, I would have a simpler, cooler running boosted 2024 GT if I would have gone with a centri.

OP,
what mode are you driving the car in? Normal? If so, give SPORT mode a try, without using the paddles first. It wakes up the car as does turning traction control off and then if you REALLY want to get daring, there is a way to COMPLETELY turn of traction control as well.

I’m a little surprised by this. I’ve found my (gen5 stg2 on a 17 GT) hits full boost (I have a mechanical boost gauge) as soon as I go deep into the throttle, and even my 305 drag radials spin on the street, at low rpm. Just as any PD sc should behave. I’ve also noticed on logs that the timing starts conservatively as engineermike said, on the Whipple tune. Maybe that’s it. Should still massively outperform a centri at the low and mid ranges. I’m not really sure about this but I think it’s a bit less efficient in general than a Roots-type at lower rpm but is more efficient at high. Not sure how it compares in that way to a centri at high rpm.

anyway, for sure the conservative and CARB approved Whipple tune is soft at low to moderate throttle. It doesn’t feel like an NA LT1 just driving around town. I think there’s something called “Performance Enhancement” dictated by CARB that also contributes to the softness at <90% torque demand.

Still, definitely dyno it and see if something’s wrong.

Spare me the dyno charts lol, ok then apparently it’s fake torque.

You're doing it wrong I guess.

There's a massive difference between a ProCharger and Whipple at low RPM. One makes boost the other does not.

Only when you hit it hard does it start making boost

Were you under the impression that the Whipple makes boost at low throttle inputs? No supercharger works that way.

If you drive the M6 version of both cars it's a night and day difference.

You're right that the 10R80 versions of both will downshift etc etc. But you're suddenly not at low RPM anymore...

Hello all,

As the title states, I'm a little disappointed with the Whipple Stage 2 supercharger.

It doesn't have the down-low punch I was expecting. Honestly, it seems to drive like stock until I get over 4000rpms or so.

It's making boost, no CEL, everything is hooked up correctly & I'm running the Whipple tune.

I'm just really underwhelmed, I expected 700whp to feel more powerful. Should I look into an aftermarket tune?

weird. Should feel like a rocket launch, pushing you into your seatback.

how are your 0-60 and 1/r mile times?

I guess feel could be subjective, but times and mph will tell the factual story. If times and mph are what they should be, then maybe your feeler is miscalibrated? But really you know when you’ve floored a supercharged Mustang. Spacex rocket launch typ feeling.

I know very well how both work, since I have one of each. I know when the Whipple is running on the bypass at lower speeds/high manifold vacuum, so there's virtually no additional torque being produced. The Whipple by-pass valve is not really tune dependent, it's vacuum actuated.

I know all that.

I was expecting to feel a noticeable difference at lower rpm, just like BigBrian27, with the Whipple.

It simply doesn't work like that in the real world.

always wondered, never asked…thanks for that

Because you have an automatic that downshifts

Well, Hmm. Not sure about your setup, but I too have a Whipple setup, heck it's a stage 1. It's tuned by Steeda. Yes, I can drive it normally. But I do not "need to get into it." I blip the throttle, and she goes. HARD. The scary part is that she does not feel like she is going hard because it is not a violent "OMG" feeling. She plants, and she goes.

I guess all those Steeda mods really do pay off....even in a straight line. Last thing, I do have a 6-speed. So, rowing the gears here.

that’s cause you were…

Be sure your heat exchanger fluid is fully topped off. If no other issues, consider a throttle controller that will give you the ability to dial in instant torque/response. Aftermarket tuners can increase your throttle response as well. Good luck.

 

[sabtaj1]

Maybe your bypass valve on the whipple isn't working correctly?

 

[Franky16]

I believe the bypass can be adjusted and tuned to coincide with the adjustment

It has to do with how the PCM is programmed to control the engine. You’re expecting it to make more torque during conditions where it’s not programmed to make more torque.

Your tuner could easily adjust the calibration to give you the feel you’re after if they wanted to.
