Can't see numbers but with that setup I'd expect you to top out around 300hp/325 torque at 24psi and 85% duty cycle

Put some 2-stroke oil in the tank? I do that occasionally to make sure everything is lubed.

Anyone have base fuel pressure drop with e90?

8 year old (15000km) walbro 255, that’s been running E for 5 years (12000km) with id1000’s. My filter is a fuelab 818 6 micron micro-fibreglass element and I have a turbosmart mechanical gauge after the filter on the supply to stock fuel rails with a stock FPR.

When I start the engine the fuel pressure is at 33 psi and with FPR disconnected 43 psi. It stays like this until well after it’s warmed up(engine oil at operating temps), but at around 15 to 20 mins after completely warmed up my base fuel pressure drops from 33 to 28 psi and 43 to 38 psi with the FPR disconnected. No change in idle AFR or trims. My fuel pump duty cycle is set at 74.90% to 14.41 psia.

Can the degradation of e85 cause this type of base fuel pressure drop?

It’s not a daily and sits for months sometimes and I’ve only just fitted the filter, gauge and started a Carberry rom tune. Had been running the stock fuel filter and changing it every year.

Do you guys use e85 treatments?........such as lucas, vp or nulon

All thoughts welcome.


Merry Xmas

Im trying to sort something out with e85 and spark plugs.

while doing research on here the info i came across was with e85 you should do one step colder plugs. with a modified motor making more power over stock plus e85, its two step colder plugs.

but, i came across instances where people running one step colder plugs on e85 in cold climates like the midwest had trouble starting their cars during the winter until they went back to oem plugs.

the reason i ask is because im running a jdm ej205 with avcs that uses NGK PFR6G as oem plugs. im not sure if i should replace with the same plugs, go one step colder and which plugs would be the one step colder for the jdm ej205 w/ avcs, or go two steps colder since the engine received an upgraded brand new 16gxt, sti tmic, aps inlet, zerosports elbow, id1050x , iag rails, upgraded lines and FPR, full tbe, uppipe, etc. this motor is going into a DD which will see chicago winters.

I run bkr6e with a vf34 set up with over 300 whp.

When I was running pump 98 before switching to e90 I was running bkr7e.

I run 1 step colder on my EFR 6758 @ 26 PSI. I originally put them in while on gas and a TD05 20G. That said, I wouldn't have an issue running a stock plug on this setup (E85).

As far as cold starting for referenced cars, I'd need to know way more info on said car and tune.

one step colder is a good idea at this level as others have noted, the cooling effect of E85 may (relative to a built motor on pump gas only), somewhat negate the need for a colder plug though at least from the perspective of preignition from a relatively hotter OEM plug. On the other hand lots of renouned builders use the OEM plugs.

Just fitted a fuelab 818 6 micron micro-fibreglass inline.

Don't know if they are any good as I'm yet to test drive.

Any thoughts on these filters and my fuel pressure drop I mentioned a few posts back would be much appreciated.

I use the same filter and seems to do what it is designed to do.

As for your pressure drop, what pump and injectors are you running?

Stock plugs it is.

Hopefully I won't have that issue so won't even need to address it

hard cold starts in cold climates with E85 or higher is completely normal. Its just a characteristic of high Ethenol %. ITs still a quirk WELL worth putting up with for the power gained with E85.

It's not my car, just a customer car that I tuned. I have never really tested really cold starts on my car as I don't drive it in the extreme cold. My car also does not sound like a Subaru, so the video doesn't sound "good" to me other than it firing right up.

Is your pump hardwired? If you're getting a pressure drop like that, I'd probably start with the factory FPR. I've seen quite a few fail over the years... Two in the last couple months with customer cars, and I do this as a side gig. They also made things like hot starts seem more like a -20 cold start with constant cranking.

No my pump isn't hardwired. Hot starts are instant.

Only noticed this since flashing carberry rom as I fitted the filter and under bonnet gauge at the same time.

Did you replace the stock FPR's that failed with standard or go aftermarket?
