Question for guys who actually have the the Roush Kit

[engineermike]

I think it will in the midrange.

I think it will in the midrange.

Makes 14.5 @5600 on a 2.7 now. Then drops to 13.2ish. At 7500.

is there any way to utilize the factory traction control to improve safety/help keep the car on the road? If so, does it depend which year car?

This is interesting. I reached out to DRP Motorsports for the info, after seeing this YouTube video. 88mm pulley. 3.4 inches. .4 inches larger than stock. With porting and larger 103mm TB they are seeing 11-12 psi boost on an 88mm pulley. Porting and larger TB must free up 3+ psi of boost.

@Autopart101 we may see some better numbers from them soon as I hear a smaller-than-stock pulley is on the car now. I can’t imagine less than 850…

Porting is my next move. I was going to test 2.5 pulley. This video tells me all I need to know. I did also speak to Joker Porting. They claim 2.5 psi boost gain on stock pulley. This kit may well be able to push 900+ with Porting and 103 TB.

Isn’t that your old car engineer Mike?

No, the first and only Roush I’ve owned is my current 2020 truck.

How do you like it? I’m considering getting one.

The truck is great, but the Roush tune totally neuters is much worse than the cars. I’ve modified the cam timing, shift character, and shift points and the truck just came alive. I went even further and made a flex tune utilizing the stock injectors and pump and it’s even more impressive. I’ve clocked 0-60 times in 3.3 seconds, almost a full second quicker than stock.

Egad...this thread is still active. Stymee must be proud. I haven't been on here for ages since I sold my Mustang over 2 years ago. However, I am now looking for another one....maybe a '20 or '21 model. We have moved and there are no dragstrips close by so I want a 6 speed manual this time. No plans for supercharging but would likely get a tune.

Still here! Enjoying the cooler weather and back on a Wengerd tune. Car runs strong! Still hate having Cat's back on the car but they go away in July!

On the street I don't take it off. TC is always on. I run 20" DR's and they hook on the street if I leave the nannies on. On the strip I have run an 11.4 @ 125 with TC on. I have also ran a 10.7 @ 135 with it off. If I turn it off on the street i'm not hooking til 65mph or better.. By that point, I've lost...

You lowered at all with those 20" rims?
