So how do we think a stock car is going to hold up to the Whipple kit?

[rockstar B]

I'll be close to pulling the trigger on one of these after the first of the year, but I'm wondering about just basic longevity. I know any kind of modifications are going to negatively impact the life of various parts, but I'm I going to be shredding my clutch immediately? Can the MT-82 and rear end hold up without exploding? Any other known concerns with older S550s and kits like this? This is for a 100% street car.

When I went this route in the S550- Better struts, shocks, sway bars and half shafts were necessary. Many with the base MT-82 didn't fair long based on the 6G forum. The 10-Speed held up robustly it seemed. Many upgraded oil pump gears to accompany the SC.

How stock is stock and how aggressive are we wanting to be?

Let's pretend we're installing it with no other modifications with no intended track use.

Everything’s cheap abs plastic ..don’t expect it to last a decade

Haha right? OP should definitely expect it to last for sure the lifetime of the warranty.

How it will do on a stock car depends on how you drive it. But unless you try to kill it I would say the 5.0L will handle just fine. There are tons of Whipple 5.0L stock engines doing just fine.

Mods will depend on what you want to do.

While no mods are necessary. I don't think I would ever install any form or FI on a car without some suspension mods.

I have never done oil pump gears and don't plan to on the Mustang. IMO not needed unless you are looking to run big power and rev the shit out of the car. But if they bring you piece of mind go for it.

I heard stronger half shafts are a must

For an MT82 car being on bias plys is critical, you need the wrap and flex from the sidewall to absorb the shock.

Hoosier QTPs would help the trans, half shafts and clutch have a longer life, a sticky drag radial is just begging from problems and breakage.

Or.. be on a hard street tire and plan on spinning whenever you get on it, free spinning will help extend life too.

I would potentially be tempted to review the warranty exclusions for hints as to the items ‘they’ suspect would be problematic. Although for mostly show and the occasional (light) go I ‘think’ she’ll hold up just fine.

I’ve been pondering and researching this exact question. First and foremost, if you drive aggressively your whole drivetrain is under much more stress with FI. If you plan on doing digs…launching hard, then the half shafts and possibly driveshaft are at risk (ESPECIALLY with manual trans). Clutch and manual trans are also at greater risk doing digs. If you limit yourself to rolling sends, you have less to worry about. On street tires, you are far less likely to pop a half shaft under any conditions, sticky tires create more of a threat. I personally will seriously consider upgrading half shafts for peace of mind even tho I have the 10-speed and will run street tires. I also have a pro street car with 8-71 blown big block that I’ve street driven for 26 years so I’m no stranger to FI lol Tire spin is frustrating, annoying and destroys tires, but is a blessing for protecting the drivetrain.

Here's Igor's 2024 dark horse with the 10 speed automatic. He's been beating on it pretty often and drove it down from NC to put it on PBD's dyno to see how it would do compared to our MT82 GT. His car is 100% stock other than the Whipple stage 2 kit and it was running on pump 93 with no octane booster.
