Another ESS thread.

[cbrtrx]

I figured I'd post up my results with the ESS G3 because I see some people would like to see some more numbers. 10r80 car with 3.15 gears.

The kit arrived fast and was very easy to install and went together very well. Mods are the following.

ESS G3 blower on 120mm pulley exactly 10 psi at 7600 rpm.
Longtube headers with custom corsa catback.
ID1050x Injectors with boost a pump and Lawn racing rail mod.
Ford racing m50a ngk spark plugs.

I'm self tuned running 17 degrees on an approximate E30 blend simply because the 93 in my area isn't the best. My next upgrade will be to go full E85. I've found it still to be very knock limited on a blend.

The car is currently full weight and on 19 inch nitto drag radials, weighs 4100 pounds with driver. There is some tire spin with the 19s between the shifts you can see in the dragy. It ran a 5.69 60 to 130 in humid air posted below. I used a seperate DA calculator and it was showing the DA was closer to +1400, the dragy is often wrong with DA. In much better DA I'd expect a low 5 and with a full drag pack I'd expect it to run a high 4 second pass from all my past experience and tuning with data. Again that would be with the 120mm pulley and in good DA. On a 110mm pulley and full E85 I'd expect a low 4 second pass in good DA. As it sits now though it would be a great street car at this power level. Just wanted to give some times for people that may be interested in an ESS for their s650.

IDK what suspension mods you have, but if you are looking into some aftermarket parts, give me a shout. We have just about everything you could need to get the car running faster times with some upgrades.

That is really fast, wow.

I know you are going to 110, but I am insanely curious what the 120 pulley would do with nothing but a change to E85, especially since you are getting a knock retard still.

You mentioned 10psi at 7600. At what rpm is the car shifting?

That run was shifting at 7650. I'm going to try different setups over the winter, right now in Florida though the humidity is too high to run a decent time. My fuel system is pretty much at it's limits, I'm still on the stock fuel pump. Pressure is fine now but I have to leave ample room for when temps drop.

The car will pick up substantially in better DA. With a 120mm pulley on a drag pack in good DA meaning close to 0 or even better if negative it will drop into the 4s. Even in positive DA though now this can provide some good data for some people.

I know this info because I have over 500 logs and runs with centri blowers on coyotes. I've repeated these results dozens of times now. I can see where everything is projected to go.

Nice!!! Mine is at Brenspeed now getting a G3x installed with catless longtubes, 1050s, OPG and the ford racing plugs with a BAP as well and with Wengerd tuning it. Im gonna keep it on the 120 pulley and 93 for a while. Next steps will be a trans and a fuel system

Yeah 17 is too much. 15 is the sweet spot. 17 is what i'd run for full E85 cars. Maybe 18. But 14-15 for 93-e30. Ive tuned several ESS s650s so far.

@cbrtrx Im local to you as well.

The knock sensors are adding up to 17 everytime. My base timing is 15. With the blend it seems to be happy right at 17 peak. This also has full 3" exhaust and I worked on the cam timing which helped with knock.

Id have to see a log. But your set up on quality 93-e30 likes about 15*. You'd have to put it on a dyno and see if that extra 2* is doing anything. You might be on the edge of knock, but thats still too close for boost. On an NA set up, its not a big deal. But with 12:1 compression and 10psi, its a gamble. And on top of that without some low side fuel system, e30 is pushing the pump as well. Every single one I've done or looked at logs for on the 120 pully trying to be full 93 or e20/30 was seeing low side pressure droop.

Some people are ok with that on newish cars with newish pumps, but I wouldnt be. You are one small hiccup away from starving the rail, then popping it with bleeding edge spark. All my opinions here its your car and you're tuning it. I wouldnt run it that far tho. I'd be happier with wengerd's dual pump kit on there running a bit more spark to see how far it would go. But then at that point you'd just go straight to full E85. Be done with it lol.

I understand, in testing the car would actually add up to 18 at times but I have it capped at 17 with a base of 15 like I mentioned. Like I said the free flowing exhaust and cam timing all played a role. Fuel pressure is not an issue at all right now either. The lawn racing rail mod gave me back just over 15 psi more fuel pressure and I have 1050 injectors and a bap. I also made some di injection changes as well which all help. Lift pump fuel pressure is very stable in this weather but yes I wouldn't push it anymore because I like a large enough safety margin for cooler weather. Fuel system is the next thing I'm working on.

Since you got the lawn rail mod, just get his dual pump plug and play kit. Similar to Wengerds. They are both quality and will provide the tune file data you need to make them work. I'd like to see this car make some runs at some point. I go to BMP quite often. I have a new project car Im taking there soon for T&T.

I'm trying to hold out for the new dw550 fuel pump but they keep pushing back the date. If it lives up to it's specs it should be enough for what I'm trying to do on e85 and a very inexpensive alternative. Probably though I'll put something together though before that if it doesn't get released soon to test.
