Power dilemma - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

gmanvilla1@gmail.com · 01-04-2016, 11:31 PM

Dilemma; I purchased a new 2015 FRS back in May. Like most of us in this forum... I would like more power however I don't want to risk blowing the engine. IMO turbo is too risky, Supercharger is also risky and pricy and there is only so much this motors can take. How much of a risk is it to run E85? I do hear many guys are happy with the performance from E85.How much power would I really gain and is it worth the risk? I am not looking for huge numbers, just want to get rid of the dip and a little more torque would be nice. Here is what I have done to the car so far: Borla exhaust, drop in K&N air filter, coilovers, wheels. I understand headers would help a lot but since I am already running an exhaust it might be too loud for my taste. If I sell it, I would lose my ass since I put a lot of money down and already invested on wheels and coilovers, I tried that route and I was offered $20k when I paid $27k.. which included exhaust and leather. Any advice would be greatly appreciated. Please no "smart ass" comments from the "kids" in the forum would also be nice. Thank you.

That sounds great. Glad to hear. Thank you.

Yeah, 85 tune is all you need. I ran it for a little over a month and a half. Only down side is I had to drive 40+ miles to refill. MPG was lost by about 8-10 (city/hwy mix) and I just got sick of the drive+$4.17/gallon.

It was fun while it lasted.

I got my e85 stuff from Visconti. Bought it from a member here for a little less than $700.

Not worry about the loss of MPG as long as there is a fair gain in power. Thank you.

In alot of cases it's not so much the modification that puts the car at risk, it's the tune. With a bad tune even something as simple as E85 can ruin your car. Same goes with FI. Running too much boost and bad tuning will see your engine out the door quick. Low boost and safe tuning will see your engine last a lifetime. The problem is people always want more. They get a taste of what these cars are like boosted and they start winding up the boost, to hell with the fuel map and to hell with the engine! If you run with the manufacturers specs and get the right tune you'll be ok

I run e85. 200hp at the wheels, instead of the crank. I use flex fuel to guarantee my timings and stuff are right(turns out no one actually has 85% ethanol here. Usually 80 but some stations run 70% year round). Totally safe to do. There is the Phantom electric supercharger you could look at too. I think headers are the only way to really get rid of the torque dip. Just keep your stock parts and swap them back before you sell it

You want to mod and tune, yet you don't want to blow the engine.

Makes sense.

Be yourself! Don't let one person deter you from your dreams!

At least thats what my parents told me when I was a kid.
