E85 has less total energy per unit than gasoline. But with the octane difference you can fuel and spark more agressively.

the other thing that used to be brought up all the time was ethanol vs aluminum. shouldnt matter as the housings have an insert which is also coated. cant think straight now but is the LIM alum? From reading it sounds like older rotaries have had a little issues with high concentration of methanol not liking seals, but i couldnt find anything on what ethanol would do.

 

regarding e85, i have dome some research and found out that you really need around 30% more fuel injected to power the renesis. thus you need bigger injectors and upgraded fuel system. also people do have problems with e85 when it comes down to lubrication. thats why most rx7 owners i have read about premix all the time. with a decent ratio you shoul be fine keeping your seals lubed. there is many more reasons to why switch but i dont feel like writting them down....

also for whoever said there is no customers that have hit this 414whp.. wellgive me around 2 months and i should be there. now if im correct, all you guys stated with your turbo, upgraded coils (bhr) and 380/1000cc injectors and good tune we can reach that right? if so ill be there soon. now im a 19yr old that works hard to do this, so if i can do it, anyone else should be able to.

ps. ny goal is reach that 500 level too. doing custom e85 setup too. now my question is, should i upgrade my seals? and what other mods besides upgraded cooling system and some ai.
thanks

I assume with 30% more fuel needed to achieve similar power, fuel economy is completely down the drain? like <10 mpg?

I too will try to get up there. I dunno though, I might be too much of a ***** to push the engine that high. Everyone has me all paranoid about my 04 engine. First things first though, I gotta sort out a problem, and also get my car fixed up from it's hit and run.

I will say that the base map the Esmeril guys programmed into my Int-X is a thing of beauty. I've been DD on it for over 5,000 miles.

 

Yes most people see mpg go to ****! prob at 9mpg i would assume.
Why don't you get an engine rebuild? and if you dont, try meth injection. That **** cleans your insides up really nice over time.

 

i get fuel mileage in the single digits during track days. totally stock too.

at VIR, both days. first day ~7mpg. second day ~8mpg.

 

my na car only get 9.3mpg on track days.. i think it is a wash.

turbo = better mgp, how odd is that?

beers

 

probably because turbo'd cars are individually tuned

 

turbos were originally designed to make engines more efficient.

as long as you stay off the boost afaik, you are good.

 

So if you stayed out of boost you wouldnt see decreased mileage from E85? I assumed you would because I thought you would need to burn more fuel to make the same amount of power required to cruise.

@Whitesnowflakes - yeah, I'll get a rebuild at some point down the road.

 

You should see a decrease on mpg with e85 no matter what. Now the amount would be up to the tune to decide. This is what i believe.

Also Esmeril guys are coming out with a e85 kit, lets hear from them about it. Im sure they have ran e85 in their car already

 

My mileage changed a little with E-85. MM is right though, if tuned properly your highway mpg shouldn't change that much. Its the city driving, that goes to hell with FI and with E85. I was getting about 14mpg combined on gas with about 60% city 40% highway driving(Compared to about 19mpg combined I used to get with the stock car so take this into account, MN fuel is oxygenated). Under the same conditions with E-85 it only went to about 12.5-13.0mpg combined. My highway mpg barely changed. My city mpg kinda sucks but it isn't that much worst than when FI with gas. And the E85 is usually around a dollar cheaper than 91-92oct premium and it behaves like VP fuel so it makes sense to me.

Wow thats pretty good, i had thought we were gonna go down to like 10 mpg. And yeah this in the city of course. I hardly drive on highway.

 

The mileage I wrote in my post is combined 60% city and 40% highway. 100% city would be worst.

Chris

 

Yeah city sucks.
Now i was planning some trips this summer with the rx8, and if i go e85 i would have to find pumps. So i did some search and came with this good page.

they will map your route by e85 stations

 

Nice NICE NICE WOWOWOWOW

 

Good Work! 414WHP!
As for your customer service wise, from reading some posts, specially the failed turbo AlTitanium's.
I just thought maybe its better to let the customers know what exactly they are buying.
It's more of trust on reliable product and service that matters than time of delivery and waiting of production.
That's just me.
Knowing what I am buying is worth getting to know after-wards and say I should have gone other ways.
Specially buying unworthy merchandise, which I thought would have been worth the price and it turns out bad, I will be very unsatisfied and I will feel cheated.
If you stand by your product quality, I think its better to let them know.
It may be hassle for you to go through all that, but after all they are your costumers, they are paying for what you built and if somethings goes wrong they will get back at you!

 

It'll never happen, and for good reason

 

Im pretty sure they stand by their products. Now if you buy used and from some one else why should they? I doubt if u go to greddy and tell them you bought a used kit and the turbo was faulty they would even offer your some type of help. Of course at ur cost sure.

 

your quite correct.

that doesnt negate the fact that a turbo that was still sealed in its original shipping(from Esmeril) packaging failed right out of the box...

and it doesnt change the fact that Esmeril wont say where the turbo comes from, and considering it looks and has all the characteristics of one thats known to literally split at the seams..

 

Seal or not, a year later is a long time. Many things could of happen that the first or second owner weren't aware of. But maybe it was faulty completely, but that's why when you buy something you tend to "use" it, thus you would know it was faulty out of the box or not. Now do we all know why the guy didn't put it on his car?

 

i totally feel where you're coming from... I'm the guy whose trust has to be earned though, thats all. By nature i dont trust anyone else with anything important unless they've earned it. Especially when it comes to things that are important to me... ie money/car.

Esmeril has not earned my trust, and in fact their methods of dealing with legitimate inquiries and some minor other issues have put them much further into the untrusted category and i have serious suspicions about whether or not they are in fact a shady company selling cheap junk to 8 owners for prices of quality materials. Come up with another explanation for me....

 

This it totally true, it is your money and you can judge them how ever you want. Which is cool. No to my understanding they are offering a "kit" that is capable of what? 400whp for under $6,000 (note kit is 4500+ your choice of coils+ emu) so that's a reasonable number. Now if you want a genuine turbo that would probably jump another 1500?? plus the other parts and what not. So at the end you could probably be paying around $9,000 for the same kit with "good" parts. So i think you should be well aware of what a kit with that prices, comes with parts that might not be SUPER QUALITY MADE.
I just think people expect a lot of things from a 4500 turbo kit.

 

i dont think(hope not) anyone paying attention expects more than what they pay for here...

i just dont like the idea that Esmeril insinuates or states that what they are selling is comparable in quality to what you would expect from Garrett etc... because that would be too good to be true, and you know what they say about that..

 

Yes i wouldn't either. If my turbo goes bad, i will replace with garrett or one with better quality. That's if it ever happens.

 

I concur.
