Supporting mods needed when boosting a Mustang GT

[gcadorette13]

How about some better diff bolts / mounts ?

Wouldn't be the worst idea. I have snapped mine.

Is there a need for a bigger radiator if he’s going FI and to the racetrack? What about driveshaft?

I’ll be going FI soon and have been wondering myself…

Upgrading the driveshaft is never a bad idea. Carbon fiber is stronger and safer, but also more expensive, than aluminum. But one piece in either aluminum or CF will be a good upgrade. If you plan on running a sticky tire and will be doing a lot of launches, upgrading the half shafts is a good idea too. Probably not as necessary on a street tire

I wonder about making a 2 piece out of CF and using a hard urethane center bearing support?

It would be strong but street driving would suck, imo NVH

 

[TrackMustang]

What are the benefits of a one piece over the stock one, is it just strength? Are there downsides?

All my race/track experience is two wheel, I’ve never had to worry about a driveshaft before

I don't see why one would need a driveshaft upgrade for track duty (road course).

So are the benefits mostly seen from a stop to putting heavy horsepower down on a tacky drag strip?

Mostly strength and the with the two piece there’s another potential point of failure. Downside would be potential NVH. Some say there’s higher NVH with a one piece (CF seems to be a particular issue with some) whiles others don’t really see much of a difference.

I'm looking at the Roush Max Cooling kit next year. Assuming Meadowvale can solve the issues with the stalling and I don't end up throwing up my hands and selling the car.

Probably be worth more to get the driveline angle at optimum angle. Iirc the s550 engine is up too high, and the drive shaft to pinion angle is too steep.


I just recall reading something to that effect..

A Centri benefits from a torque converter too if you’re look for max ET

Keep boost down to 9-10 max, Cats can fail with boosted cars, they clog and kill engines….

- Indy 500s tires (275 front, 305 rear on 20' wheels)

Start off with better tires. Those will get smoked even at modest boost levels.

With all that money and effort you put into the car, it would be disappointing to hinder it with crap tires. Those are decent budget oriented summer stuff, but they won't hold up to boosted power.
