Nope just a friendly heads up I know how to make what I do possible and not play in the name of testing. If you want to finish mid pack and call it testing cool. I just like having the work done when its time to go

Guess I'll be clearer, stroking your internet penis isn't going to win you any points with me.

I look forward to your future posts.

Now if it were put into the context that I would be upping boost beyond a threshold simply because of the detonation reduction qualities of a high grade e85, maybe I'd understand. But why would you need forged pistons and rods to run e85 on a boosted application for any motor if the boost would have otherwise worked well on 91?

Edit: under assumption that fuel delivery is more than covered

I assume you switched fuel for more power if not why switch. I have run E85 for over 2 years N/A and never once had a problem and it was a hard 2 years. I would ask the guy that told you because I disagree with his statement.

Some people you just cant reach, so tell me what you have done to help this platform.

This was auto authority, theyre more familiar with the 4G63, 2rz/3rz, and 3tc motors. I want to switch my boosted 2rz to e85 for greater tuning leniency, and we tried translating the discussion across multiple motors including the fa20. His discussion-ending statement is he would never switch to e85 on a tired motor or a NA motor that's been converted to FI without forged internals and rebuild.

I've been a bit confused by this, as we were discussing pauter rods vs. Eagle up to this point

I wish you put the kind of effort you did in this post in the original post. It got my attention.

Sorry my post didn't help you but it was more for the ones that haven't put the work in you did.

My opinion is he is going to tune it all out for max gains with max timing and fuel on the lean side to squeeze everything out of it. That's a recipe for heat, detonation and failure. There's a reason top fuel motors get rebuilt every round. Like I said I don't fully agree with it. As far as Pauter I like them they hold 644whp and I plan to push them over 700whp
Edit: 1 more point is I see a lot of flex fuel Chevy's rolling over 100k on the hwy so why on a older model engine you shouldn't run E85 beats me. If you did switch I would not try for max hp I would just go in the middle and keep the timing at a safe point maybe -5 under max. Just my opinion.

Justin Bieber is also top of his chosen field along with Kyle Bush and Lewis Hamilton, none are particularly well liked at the moment, I am not here to diminish anyone's accomplishments nor claim I am superior.

You're right, some people you just can't reach.

Like I said, I look forward to your future posts.

Now that's funny I don't care who you are that's funny lol

Good points,

but paragraphs... Can you use them?

Maybe in the future if I do this again.
I'm way past worrying about the grammar police.

Just to do the math, to get 300hp out of a 2l engine... assuming you are an amazingly awesome (f1 grade) engineer and can get 210 PSI of BMEP out of the engine (haha), that would equate to a tq of 169 ft. lbs, so to get 300 brake hp you would need... 9300 rpm... hahaha... To get 300whp, with a loss of ~15% you would need... 10,700 rpm... hahaha... since peak hp is usually 15% less of peak tq you would realistically need to rev to 12,300 rpm...

Okay, so not possible on gasoline, so how about e85? I can't find any realistic numbers for e85... some paper claimed they got to 19 bar (275psi) of BMEP, but that's supercharged... In any event, to get down to a realistic level of ~9000 rpm, you would need a BMEP of 287 PSI or 19.8 bar (230 ft.lb of torque!!!)... don't think that's realistic...

Edit: In any event, it's kind of a moot point, the rods bear force, not power. So really, the limit isn't hp, the real limit IS the BMEP. So the reason NA hp doesn't always equate in terms of failures to FI HP is that FI boost TQ (BMEP) WAAAYYY higher than NA, and usually can't rev as high. So if the rods fail at 300 whp FI, you would need to see what their max tq is at, then that is the max tq you can hit on NA, which likely you'll never hit because it's na. In this respect nitrous can be seen more like FI, as it boosts your BMEP to rediculous levels.

Where did you find that formula? I've been looking for it in a online calculator. Thanks


Found it thanks again
