To a point, yes. Not so much if you are already running pretty solid timing. Retarded timing is where you see greatly increased EGTs due to left over fuel.

unless your at the knock limit adding advance will always decrease EGT, let me see if I can find my source

I didn't disagree with you???

Point is, you benefit from running as much timing as you can run without detonation. This isn't a recent discovery

not sure where that came from. But my point is that the cooled EGTs of ethanol allow leaner lambda ratios to be run and knock iat points to be higher, not that the lower combustion temp allows you to run more timing. which is what you initially had said

Thank you for sparking my memory. Need to order a new bung to weld into my turbo manifold for my defi egt gauge. Couldn't really just cut the old one out of the header when I sold it

Lol I was thinking that but didn't want to say it. People love to read and preach. I am going on personal experience on a car I converted to E85 that has an EGT installed in the dash permanently. Added boost, added timing, added fuel, saw changes. That's what matters to me.

Lol, small hole saw and just tell the guy buying it that it's for an O2 bung?

Well I sold it to my friend who bought my TVS as well so there would have to be some serious convincing skills

If people actually used egt's, they stop the **** and moan about intake temps on e bs.

your searing heat issues I would blame on tuner, and your car warned you prior to it leaning out in a split second and then dead motor, you had other issues. I have pushed my EGTs up over 1600* to decrease spool time (and that is a bone stock LSJ) and when I got the spool I wanted I left it there. 1300-1600* in the mid range run after run after run, daily drove it for more than 6 months that way

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.
I know you arent making me run this fuel, hence I havent bashed any of you guys that are running it, I just simply explain my opinion on the matter and what I would do if I did decide to run any form of alcohol based fuel. I respect all of you guys that make big power on it, I just ask for the same respect for me running pump gas.

keep over complicating things, I enjoy reading and learning exactly how something works instead of "um , I pour it in my car and , um , it goes faster and , um , yea" Learning what works and doesnt work helps to further what we are all doing and keeps us from wasting money on parts that break or directions that are unnecessary.

its got ethanol in it. 10%. o well. car runs fine

egt? I got 'em. I see 1700-1800 on track or at 150 mph continuous. s'alright/s'ok

I'll be putting an egt in my manifold as I learned from diesels on the farm. Monitoring everything is always a good idea

What gear are you in at 150mph? My 4th gear at 7200rpm shows 152mph on the dyno

I wouldnt know how fast mine is lol, I just see it in the logs after, was just getting an idea of what gears you would see on a road course at those speeds
