135k Miles on Engine. 110k boosted miles; still going strong
 

I think the longevity test was passed. I drive 100 miles a day to and from work with it. lol. I'm 284whp (mustang) which is about 370 crank hp or 310-320whp on a dynojet. I think at this power level, it will last as long as stock. To note, I have been using almost nothing but e85 the last 3 years.
So I deem 300-350whp the safe DD limit.
I full throttle redline it multiple times everyday. I'd say I probably have maybe 5-10k miles of full throttle events.
Which brings me to my next point; I the the FA20 is unique that is can handle double its power on stock internals reliably. I just got an evo x and to run 400whp, you need aftermarket cams. FA20 seem to be able to run 400whp with little issues if you don't have a bad engine.

Now that you've smashed out the "safe power" discussion

You can double down and put the "ethanol corrosivity" arguments to rest :)

A solid tune and e85 has also been fantastic results for me. The car is also far less temperamental during hot days and my exhaust tips self-clean. Even not driving WOT all the time I also feel a huge difference when I was forced to add 93 octane in the my car because no ethanol gas stations were around. When you are ready to do a tear down or internal engine upgrade pictures of the inside of your engine would be greatly appreciated and added to the internet community concerning ethanol. So many rumors concerning e85 needs to be put to rest.

Yup, 110 miles, conclusive, nothing else to say:thumbsup:

Awesome thanks! Pushes me that much closer to FI

How is the blower doing? Ive only got 30k on mine and always wondered how well it would hold up the way I drive

Oh have you upgraded anything else? Intercooler? Fuel pump? Injectors? All the shops I talk to seem very keen on adding them to the package and it really ups the price.

I've always hear my muscle car buddies talking about vortech blowers outlasting the life of the car. One reason why I went with them. lol. So far it's holding true.

Fuel pump and 700cc injectors. Yeah, these components will throw up the price maybe $500.

But that's only because you're running E85 correct? I don't have that around here so I'll be sticking to 93-94 octane

Good work, thanks for reporting this. What oil and weight do you run? Any time on track?

Aren't you going back to NA since you got the evo?

Well this gives me some peace of mind when i supercharge

Correct. If you are running pump gas, no fuel mods are needed. Just don't run you car hard near empty. That's one good way to kill the fuel pump.

I use mobil 1 0w-30 full synthetic. No track time with this. I use it as purely a DD. But, I think it will survive track pretty well.


Maybe. Or I'll just drive around 2 modded cars. lol
With a boosted frs, there is the joy of catching people off guard, which adds to the fun factor.
With the evo, everyone expects you to be fast by default. lol

Might I ask what your clutch experience was, and if you ran the stocker how long did it last while boosted?

Next goal, 200k miles!!!

85k and an intake valve broke, guess I am just unlucky.

One of the biggest joys I get myself, it never gets old haha.

I ran stock, but switch to an excedy stage 2 before they had an update. Miserable experience. I switched back to to the stock clutch and have been running it for a year now. Holds the 250wtq well.

That's good to hear! Been on the stocker myself for a year now, running just a bit more power than you are. It definitely is losing it's bite but I'm hoping to get another six months out of it. A lot of people had bad luck with the 1st Stage 2 design from Exedy. When the time comes I'm going with Exedy Stage 1. Never heard a complaint, I spoke with Toan @ PTuning and he told me he put down almost 290 wtq on the Stage 1.

30k and a rocker broke......

Are all you rocker eaters 2013?

People who aren't on E85 are just missing out. :D

Last time I filled up on E85 I got 100 miles for the tank..

Any details ok kit running? hp/tq? Tune and fuel? Mods?

Yea I'd be interested to see what mods/tune caused that too. So many variables at play when you go aftermarket HP, any little thing can cause a failure.

I'd consider an intake valve failure to be a freak accident that is independent of mods (assuming there are no valvetrain mods and stock rev limiter).

OP thanks for the update, definitely gives me peace of mind about my engine since I'm running 9psi vortech on 93. What supporting mods do you have?

Only mod is an ESC so I have about 200-210hp at the wheels. I don't think it had anything to do with the mod just a fluke, sucks though. I would have been boosted for real if I knew I would have to replace the motor before 100k.
