Boosted s550 mileage

[Zrussian13]

As the title says I'm curious what mileage everyone's at with their boosted GTs. I know there is 100 mileage threads already but havent saw one for boosted cars yet. Really looking to see how many guys are hitting the 100k mark on the stock engine but open for all replies.

I hit 82k this weekend but I didn't boost my car until 48k so I was slow uping the boost to make sure the car would live for a while on the stock motor. Started at 6lbs.l, then went to 8lbs and at new years up'd it to 10.5lbs. Motor and trans is stock but I use boostane and meth to help octane on our shitty 91 out here.

I have another shoulder surgery scheduled next week and that got me thinking. I won't be able to beat on my car for a few months because I'll be forced to shift left handed for a while. My worst fear is blowing it up right before surgery because I'd be forced to pay someone else to do the work. A responsible person would say just take it easy until I'm healed but I can't go a day with out beating on this car so I guess I'm looking for reassurance lol.

My set up is hellion sleeper kit (base turbos) on pump with booster. Lund KR tune at 10.5lbs (now). Stock pump with bap and dw95s. Other than that it's just bilstein shocks, steeda braces and drag wheels in the back (sometimes). Not a wild build but a good combo for a fun DD street car.

5800 for me ! But I’m semi retired for the moment and when I was working I literally worked across the street so not to many miles on mine.

Yeah I wouldn't daily mine at 17lbs either! I do 50+ miles a day. I used to have my work truck as a backup but my 17 year old son had grown quite attached to it and him driving it makes my life much easier.

Original owner procharged it, basically brand new. At approx 15k miles, swapped it for a Whipple. I bought the car at 19k and now it nearly has 40k.​

​

Car is a 17 with the MT82. As far as I know, original tranny and clutch. Has a fuel system too but like you, living in AZ has me running the standard pulley for approx 10# of boost. I'm also at 5k feet but when heading down to the valley, will throw some octane booster in even though it does have a Lund 91-93 tune.​

​

OPG/CS done a long time ago. No digs for me and rarely go above 5k RPM because I'm boring and terrified of tickets.​

How much boostane are you running at 15lbs?

How much boostane are you running at 15lbs?

16 oz to a tank =approx. 98 octane

Boosted at 500 miles, went 9.9@142 with 740whp. Turned it up at 5000 miles and went 9.3@153. Daily driver in the summer (Wisconsin....) and its 28 miles round trip to work. This is my third boosted coyote and they are all good machines.

15lbs is nuts on pump + boostane! I love it. I run the same mixture in every tank plus meth but max boost I've pushed is 11.2lbs and that was an accident. (Hit the boost button one too many times when it was cold out) I've considered taking it to 12lbs but I'm running a tune with my knock sensors desensitized because I have some false knock on shifts and would hate to get real knock at that boost level with 19° of timing.... Maybe once my shoulder is healed and I'm back in a place to throw a new engine in myself I'll push the limits before switching to E.

Meth on every tank for me. Don't trust every pump I go to

Bought at 32k, boosted at 37k (then 12lbs now 16lbs), currently 85k. Daily stock engine.

I've got 10k on my boosted gt350r, running E-85 w/ 22lbs on a built engine. Yeah my mileage sucks 12mpg but e-85 is cheaper than 93, it's a fair trade off for 1023rwhp.
It's about the same w/ my gt500 24lbs on e-85 w/ 1263rwhp.

Finally someone with more miles than me! I was starting to feel lonely up over 80k!

Im at about 52,300 miles, its a 2015 thats been boosted since jan 2017 at which point it had just shy of 19k miles. so roughly 33,xxx miles boosted.
