2016 GTS, E85 anyone?
Hello all,
I have had my 2016 GTS for almost 3 years now, bought it as a CPO back in 2018 with less than 6k miles on it.
Performance wise, I’ve installed:
Catless DPs
Pure Turbos stage 2
Upgraded Spark Plugs
Go Labworks tune with handheld
My tuner is telling me that to unlock the power from the pure turbos without having to use 100 octane race gas, I can have a HPFP installed, recommending Xtreme DI, and he can send me a new map to be able to use E85 pump gas, and gain very good HP and torque numbers.
Has anyone done this? Your thoughts? Thanks.

What about LPFP? I have seen a few eurocharged vehicles running both e85 and blended fuels on the internet. Never saw one in person though haha. But people have definitely run full e85 on their amg gts. But wow your car is gonna be insanely fast haha

Unfortunately in California we don’t have 93 and the highest we have is 91 and due to this limitation my car is making just under 600 whp. That is why I’m going this route so that I can comfortably make high numbers. There is a E85 station few minutes from my home and cost is only $2.70 per gallon.

Oh yeah I remember your old thread. E85 idea would work but I'd figure out what's wrong with your car before throwing more money at it. It should make a lot more power than it is. Find a local tuner.

Yes! I’m still dealing with the same issue. I was going to take my car to another dyno where I got all my mods installed, SSR Motorsport and have them dyno tune my car with my tuner, go Labworx, but every-time I ask both of them they blame it on the crappy 91 fuel. That’s why I decided to go this route but you have a point.

I ran E85 on my Nissan GTR and it had a flex-fuel monitor on it that fed the ECU software and adjusted boost, timing, etc based on octane content. The issue a lot of the Nissan guys had (but I never had it in 2 years of ownership) was the E85 eating seals. One of my buddies had a bad misfire issue, which turned out to be an injector o-ring that had dissolved. I did a tank of 93 ever 4th fill up, to get the detergents and less corrosive fill up.
I'd be interested to hear how well the GTS tolerates E85 over the long term, but I do continue to be surprised at people wanting such high HP in a RWD car, I run 93 and have downpipes and a tune and the back end likes to get wiggly at full throttle...

I have no idea why Mercedes didn’t use their 4matic AWD system on these cars. Ridiculous.

You’re right, I still have the stock tires and to say they least they do not do well under WOT. I will be looking at tire upgrades as soon as I’m done with the power upgrades. I never open up the car from a start. I always wait till I’m going at least 30mph or in 2nd gear.

Regarding your turbos, are they the Pure 900's? I've been considering getting a set just so I can enjoy a full power band all the way to redline.

Yes I have the 900’s, stage 2. I would definitely recommend against it unless you have access to 93 octane daily. With 91 the tune is too conservative and does not add barely any power versus just catless DP and tune. That’s why I’m going the HPFP route so I can use e85.

I wouldn’t mind the added weight with AWD any day.

I did a dyno over a year ago and was at around 590 Whp. I was told that I should have been around 650. I need to dyno time my car either way. I thought the HPFP and e85 tune would seal the deal.

E85 should make a BIG difference - I'd guess 25-50% depending on how aggressive of a tune you decide on. Best of luck with the build, I'll be watching excitedly

I was making 700whp and it dead hooked in 2nd gear on a sunny 70 degree day.

Is R888R the way to go? Can you easily drive with these? Are they terrible in the rain? It barely rains here in LA anyway. Can you go with 325’s in the rear? Thanks in advance.

My car is lowered and I am running 325's in the rear, but Michelin PS4S (those R888R might run wider or smaller) and I do rub a very minor amount over large bumps at speed.

There's no benefit to going with 325s on stock wheels. 315/30/20. R888R is louder, not good in the rain, wont last long, and follows grooves in the road. But it's the best bet if you want any traction.

which tire do you recommend which is much stickier that stock tires but is not that noisy and does ok in rainy weather?

If you actually want traction with 700+hp, you have no other option. The R888R is still a big improvement over the old days where you had to run a drag radial that felt like you were going to die every time you had to take a turn. It's a little noisy and dont drive over 60mph in the pouring rain.
