Great review. Sad for the tires though.:icon17:

550-570whp on stock internals? Wow that is hardcore, what are your feelings on the long term longevity of running that much power on stock internals Phunk? I know a few others have done so but not with e85 and don't have your experience on the matter.

well i cant quote any figures, since the highest recorded dyno was 523rwhp at 7.5 psi... i am just assuming its higher since the air flow to the intercooler is much better in this cool weather and i have been running higher than 7.5psi boost.

As for the longevity, Ive got to say that if it holds up for me, I cant imagine how it would break for anyone else. I say that for a few reasons. For one, I have a serious problem. I have a hard time not constantly flooring it everywhere I go. I have a hard time not giving it a run with any car that wants to. I cant go more than a few minutes at a time without at least giving it half throttle away from a light (half is enough to wag the tail around 1st and 2nd). I really just boost it, a LOT.

Most guys I know are much easier on their cars. One close look at my car and you can see its been through it, and driven hard.

I would never, say, ROAD RACE the car at this power level on a stock engine, I do not think the engine would make it more than a few laps (but maybe im wrong, maybe it would never break). But I wouldnt hesitate to run the boost at like 4psi and road race it.

Another reason is, I still have a LOT of tuning to do on the car. While it runs and drives really well, I would never have given a customer back their car how it currently sits. There is way too much refinement to put into the tune. I think the car will only get smoother and more powerful from doing so, but its already good enough that I am being lazy about it since its my own car.

Since my highest actual dyno number so far is 523rwhp at 7.5psi... I will say that I would have no reservations what so ever running the car at 525rwhp turbocharged. Definitely well within the safe-zone there.

Great results!

:shakes head: lol, if funny how many of us are victims of the same problem, im guilty as well. Great review, thanks for follow up. BTW, how's the oil temp treating you since the last post and for some of us average tuner, how much dedication will one need to invest with such a set? Can someone that daily drives his Z cruise around without worries, or will the hood be prop most of the time?

e85 on a TT Z, damn the simple idea gets me hyped.

Personally, I took it a little beyond in terms of the mechanical installation and preperation in the engine bay, and light modifications of many parts just for better fit or long term reliability. Just from working in the field for a long time and seeing what lasts and what doesnt, I am left unable to simply attach any part someone gives me without having to go over it all first, usually picking at a few things to change, or upgraded/swapping the hardware or plumbing, etc.

I am not sure if I mentioned it earlier in the thread or not, but I put over 200 hours into the install. I could have tossed it in with probably 50 hours work, but to spend such little time on my first rodeo with the 370 would result in a half *** job. I think I could do it again just how I did or better in about 80 hours now, and probably 50 the next time.

The engine bay is different enough from the 350z that I had to learn new tricks, angles, custom tools, for working about the difficult spots.

With all that time spent, I would be rather upset if I had to open my hood for anything at all! I am proud to say that the hood has only been opened to either show someone the install, change/check the oil, and, well, thats it. I have not had a single mechanical problem requiring any attention. Nothing has needed any adjustment.

I believe this setup can be very reliable for DD. Key points for reliability being:

1: tune quality
2: oil/fuel/etc fluid quality and maintenance
3: high quality plumbing (this means quality hoses, no crappy fragile T fittings, no crummy vacuum hoses, proper heat and abrasion protection to all OEM and added hoses).
4: quality hardware and gaskets. i dont usually use anything given to me in spots where i expect it to last. i can expand on this if anyone needs.
5: keep it simple, dont over complicate. some people tend to just buy everything they can find.... part A doesnt fit right with part B, or you overwhelmed the installer and they rush through the last of the stuff, etc. use what you need, get it tuned and done. if you need something else later, add it then.

In regards to oil temperature, I for sure need a larger or a second core now. The last few days have cooled off significantly, we are in the 60s/70s, oil temp for street use has been no concern. However, last week and labor day weekend it was high 80s low 90s. I could keep the oil around 200 degrees if I drove it like an old man all over the place... but within about 30-40 seconds of hard driving, I was at 220 and climbing. I really dislike passing 220 because I believe that is when power reduction begins in the ECU tuning. I swear I used to feel it when NA, and I swear I still feel it now.

il tell you what, its cheap as hell. usually costs me 58-59$ to fill the tank from when there are zero LEDs left and the distance reads --

I love it. The 100 octane I used to run in my 350z was twice as much.

With the E85, you do definitely notice the reduction in gas mileage, there is no denying it. But its not so bad, it doesnt bother me. Only one thing about it sucks... my 370z, the fuel level reading is a lot more sensitive on the lower end then it is on the top end. I can drive forrrrrever on the first half tank.

the second half tank... not so much. I can barely get anywhere. If I leave my house with 5 dots on the gauge, seriously 20 min later I am at 2 dots and need to get fuel ASAP because I am almost out.

Last week I actually had a hilarious close call, my car ran out of gas 5 feet from the E85 pump. I know I was going to die any second I actually blew 2 stoplights and a stopsign on the way.. The car died a half block from the station but I was goin 50 or so, I was able to coast in and navigate all but the very last turn up to the pump. LOL a lady at the pump next to me helped me push it up!

How complicated is it going over the e85? Thus far you're the first and only one, is it as simple as running the right injectors, fuel pump and lines and tune?

You pretty much just need to make sure you have enough fuel pump and injectors, then fill the tank, and retune.

While the 370z fuel system isnt "rated" for E85, there is nothing about it that is going to have a significant reduction in lifespan that will you notice except maybe the fuel pump itself. While walbros and aeromotives and DWs seem to do OK with E85, I have been told that none of them are actually rated for it, and lifespan is reduced.. but supposedly not enough that anyone would care.

All of the factory plumbing is fine for E85 though, its all coated steel, teflon, and nylon.

We will see, this is my first E85 ride!

Rep for you Phunk thanks for taking the time to answer all my inquests.

clearly a lawyer in the making... :roflpuke2:

Phunk are u using a boost controller. If so, which one? Sorry if it was mentioned before, I missed it

Almost, in my final year of school....ever. Though I can't lie leaving a college campus and the college girls will be a bit sad. Hopefully I'll be starting my own Z power overhaul post law school.

currently i am using an HKS EVC5 i think it is. its the one with the silver housing and blue backlight with white digits. i like it a lot. I yanked it from my 350z lol.. i installed it in that car when it was the latest greatest.

I dont know if any of the newer model controllers can hold boost better or not, I havent played with them. Just like in my 350z, if I want i can make the boost have a rapid spike of a couple psi if i mess with the throttle just like, like stabbing it on/off when its already at full boost... that will usually make it spike to 10-11psi just for a very brief moment, like a tenth of a second, but enough for the peak hold to catch and save it. I dont worry about it.

buuuuuut i am sort of eye balling the new EVC. i need to compare the dimensions on it and see if it will fit in the holder i just busted my *** making for my old EVC. let me post a pic of that in a moment
