and as far as messing with the tune all the time, screw that. June 2012 is the last time an hpt cable touched my car haha

 

Damn has it really been that long

You don't count though, you probably haven't put 2000 miles on the car since then you queer.

 

just over 7000 miles. just got my neutral balance shafts. only thing i'm missing now is the cams themselves

 

this and you wont have to worry about RD fabs heat soak IAT issues.

 

Are you dense? I dont have heat soak issues. reading>you

All metal intake manifolds heat transfer. E85 will not increase or decrease my IATs anyways.

 

it won't decrease IAT's but it will severely lower your cylinder temperatures. e85 burns much cooler and considering you have to use so much, were talking several hundred degrees at WOT

 

It's amazing what you can get away with safely on E, the fueling and timing would have EGT's melting stuff on gasoline.

 

your gonna have some tuning ahead of you sir

we're gonna have to crank the fuel pressure to get it to keep up for another 1000rpm

 

Whatever, your car is easy enough to tune now, I have all the MAF tables down pat. From there I can make straight adjustments and just log for fine-tuning.

You also have realistic expectations, and know that the idle may not be perfect with firehose injectors, etc. Car will make rape-tastic power though, that I can guarantee

Hopefully I don't pop another axle logging

 

Im ok without e85

 

lol i agree, greedy fuel with not a lot of btu in it.

 

what's funny is everyone who is currently on e85 would never go back to regular pump fuel we're not all crazy

 

orly?? lol

 

Ysrly

 

wrong

 

I leaned out once on gas, melted valves instantly, rebuilt my block, leaned out again and popped my cylinder.

Leaned out on E85, after my third engine build, pull after pull and never had the searing heat issues I did with gas. Its just safer if you plan on tinkering and testing.

 

I havent tuned since I got off the dyno in July. 6 months without using my HPT.

 

E85 does not cause an iat different that we can measure unless you put a thermocouple by a valve.
However, ethanol does vaporize in a similar manner to meth, so post injection, It DOES cool iat's.
there's guys on the bullet, and my dyno shop guy has seen in person, blow through carb guys on e85 that the manifold is below ambient temp after a pull on the rollers.

The biggest thing here, though, is that combustion and eg temps are what do the damage. E burns so much cooler that you can "get away with" much higher inlet temps than on gas.
Johnson motorsports is running a non intercooled pump e85 procharged drag car that runs 40+psi and inlet temps approaching 300*F. Been torn down each season with no abnormal wear.

Many many turbo guys are ditching their front mounts on e in favor of greatly reduced spool time, with less than a 1% loss in whp. Picking up both trap and mph.


There's SOOOO much more to it than most of you realize.

 

We aren't making anyone run this fuel, just have an open mind about it. I spend too much time on cruise night pleading my case convincing the older local car guys about it because they say "that **** will dry out your engine, yep your just ruining your motor". Now I just drive by and smile and pat my car on the door when I see them. 4+ years on E85 and 3+ years on a small pulley TVS not being easy on her.

On another Black Friday related note, I made some purchases from ZZP for my Red car F40 6-speed setup and s259et will be on its way! Snagged an oversized radiator as well.

 

F40... drool

And I thought I was hard about my cams and ATI!!

 

I am not saying its cooling the IAT like a shot of Meth would. Its hard to state something so simple on this site cause everyone over complicates things. I am just stating that I wouldnt waste money and time researching intakes and for the 5 degree drop I might get from an intake spacer, mod, etc. Simply put the extra cooling and octane from e85 takes care of many worries that scare guys from turbo builds.

 

It's simple: It's alcohol. Doesn't have the energy density of gas so you need more, but it burns cooler so it's safer and easier on components. That's all.

 

Well, it's not that simple. But I guess I better let that one go since I'm apparently "over-complicating" things..

 

I mean, people are here arguing that it cools better because it evaporates. Gasoline evaporates, that's not a difference you will notice in the real world. The much cooler EGT temps you will notice, in the form of the ability to run a **** load more timing and such. Two realities of it are you need more because it's not as efficient at storing energy, and it runs cooler. Yes there are more differences, but not relevant ones to this discussion.

 

increased timing advance cools egts
