E40-50 blend - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Surfdog SS · 07-31-2022, 10:17 AM

Guys so my tuner says I have enough left in my current fuel setup 60lb injectors, stock pump, and bap to run e40-50 or a cam. I'm not expecting huge gains cause I want to be in the safe zone and not max out the fuel. he should be able to increase timing some and not get knock like we were. I have a project at the house to do before I can add a cam and fuel upgrade. So I'm gonna go with flex fuel sensor and tune. Any thoughts? What is the extra demand on the fuel system running a blend around 10%?
Also he said my iat are high. Is anyone else running a centrifugal having any issues with iat? If so what are you doing to fix it?

E85 requires 30% more fuel capacity. I would not run FI on E85 with a stock pump.

Thanks, I know but I'm not running straight e85. I don't have the pump or injectors for that yet. So what your saying is no e at all? If I have the room to run a lower percentage of e without maxing out my system wouldn't there be benefits to that?

Surfdog SS · 07-31-2022, 03:11 PM

Flex fuel sensor $275 new tune $200. If i can safely gain 30+ whp wouldn't that be worth it? It would be the cheapest mod I've done.

I ran e60 on my ZL1 for while on a BAP with a 10% pulley, CAI and 90mm TB. Anything more than about e70 and I started losing fuel pressure. It was happy at e60 though. Keep an eye on your injector DC too.

What injectors were you running then? Thanks for the info.

CamaroCracka · 08-01-2022, 06:36 AM

Are you going to check your ethanol percentage every time you fill up? Even with 40-50% you are getting close to the limits. I see guys say they get 650hp out of a ZL1 pump, but mine hit a wall at not quite 600 without the BAP. You could give it a shot and install a BAP if you run out of pump.

As for the injectors, I run the 63ib Siemens at 700hp on pump gas and they are maxed beyond what most people would find acceptable, but they are stable and I have meth injection as well.

My next upgrade will be 1000cc injectors, fuel sensor and an aux pump. I'll get rid of the meth and maybe the BAP at that point.

Risingson05 · 08-01-2022, 09:43 AM

I have a fuel system installed and injectors that can handle 100% e 85 but from what my buddy tells
Me anything after e-60
You start getting diminishing returns

eLeSthree · 08-01-2022, 11:26 AM

Your friend is right. Most people will have their Multiplier VS Composition Table setup like this.

So you'll get %70 of your timing (power) gains from E60. But, how will you know what your Ethanol composition is every time you fill up? Do you have Ngauge? Plan on carrying a laptop every time you get gas? It's probably not a good idea.

I would suggest you address the hot IAT situation before adding more power. The ESS intercooler worked great for me. 108 degrees on the dyno pull making 1100whp+ no meth.

dreksnot · 08-01-2022, 12:45 PM

Then, there are "Burger Kings" that have to do it their way. Since I can only get 91 octane with 10% ethanol around here (no real other choice), I made that my baseline. And, I figure since I've heard anything over E50 runs around the same and my local station pumps out E67, I just figured I'd be close to max timing with that. There may be more right or wrong ways to do this.

eLeSthree · 08-02-2022, 07:58 AM

lol, yup, mine is 75% @ 50, but I dont want anyone following my bad ideas. haha That's why I said "most". I only add 5.5 degrees if 100% is used. (talking about the V here).

Surfdog SS · 08-03-2022, 01:17 PM

So we decided to toss in a zl1 pump and while we are in there to do the cradle bushings. Kill 2 birds with one stone. I'm just gonna see what we can do on these 650cc injectors and E40-50 for now. I'll upgrade them when I do the cam and add an aux pump. I think that will be it for me anyway hp wise. I'm not trying to push this to the breaking point. When it's all said and done if I'm around the 700 mark I'll be happy...famous lasts words! I said that about getting to 600.

dreksnot · 08-03-2022, 01:51 PM

Could throw in a Boost-a-pump for another 50hp buffer.

acammer · 08-03-2022, 02:21 PM

Meth would help with the IATs, and add supplemental fuel. I don't love meth as supplemental fuel as you open the door to distribution problems, but taken in mild to moderate doses it works pretty well. 60lbs injectors and a ZL1 pump isn't gonna take you very far on a boosted setup trying to run ethanol.

Now that you've got the ZL1 pump on board, I'd be looking towards a set of injectors, and then a cam, as the logical upgrade path towards more power.
