high compression setup

[IsaacHayes]

Jon, knowing the intake valve closing event is the main # I would need. IVC ABDC. That would help compare with what I have to get an idea. You have slightly more duration but less lift than my cam. (talking about intake side)

I did hear that ONE gas station in my city is putting ethanol in their 91 premium, which tests out at 94 octane on a octane engine. They typically don't put E10 in anything but the 87 grade (which comes out to 89 and is exactly the same as if you selected 89 grade which is why they sell both for the same price). It's required to put 10% ethanol here in the gas unless it will raise the price.

So that would be nice, but since that is a rare exception and may not continue, I hope I can run on 91.

If anyone needs cam specs, please use the contact form on wot-tech. I have the regrind sheets still.

do you mean this http://wot-tech.com/shop/contact-us/info_2.html or is there another form im missing.

they put ethanol in every grade around here and i believe its the same throughout the northeast.

[SappySE107]

Yes that contact page. It sends me emails, which I can keep track of easier than pms and forums.

All of the 7-11's around here do E10. There are a few others around here that do too, but there are still a small hand full that don't (unless they just don't mark it as 10% Ethanol).

[geldartb]

all of the places around here have a sticker on the pump that says the fuel contains 10% ethanol.

They passed so many stupid laws here. First they passed to where they don't have to label it or not. Then they made it so everything HAS to have it. Costs tax payers money is all it does.

indiana, ohio and michigan are the same.

I miss the mileage I got on straight gas. It was almost like an extra week of driving it seemed. Speaking of bad mileage, last fill up was 15mpg with the cold ass sub 0 temps and trying to warm up the car enough to see out the damn windshield. I swear I need to put cardboard over the radiator, that or when winter comes put in a thermostat higher than 195F... My co-works 4 runner will burn your face off in like 5 mins of starting the car... Mine you can sit and rev it for 10 mins and barely get luke warm. And it's not a clogged heater core or anything like that. The car just always runs cool no matter what.

try looking at a truck stop for a small ceramic heater that plugs into cig ltr plug. If you have an old enuf car that has cig ltr that is. they are small and sit on the dash to help keep your w/s defogged. trucks are not well designed most of the time. and they cant put glowing element stlye units inside the cabs. once u can see, just unplug and remove so it dont fly around during your heavy throttle romp to work.

Since people are talking about E10 and high compression, I hope you all know that your cruise/idle AFRs should be 14.1:1, not 14.7:1.

[robertisaar]

reminds me of the chart i made...

E10
Stoich - 14.1
PE A/F - 11.8

shit... That explains alot of my tuning lackingness.... I've been tuning to the quoted 12.5 or 12.8:1 YET I can ONLY get E10 in my area...

Well that's going to help some this summer when I start tuning again.

I guess that also explains why anything below 12.8 I could FEEL a power loss and was always confused on how the low end could be that close to where it should be "happy"

[robertisaar]

keep in mind, those PE numbers are calculated, it WILL vary depending on the motor. but it's a pretty good starting point.

That's a design flaw addressed in the 3900 and 3500 VVT motors. The thermostat appears to be dual stage. It has a block off for water inlet to the water pump and a smaller block off over a passage that allows recirculation of coolant through the engine connected to the heater hose so that coolant directed towards heating continues to circulate through the engine when the stat is mostly closed. That's what I devised from looking at the design when drilling a few by-pass holes into the thermostat base to allow a little bit cooler engine temp and reduce overheat risk in the event of a complete thermostat failure.
