Vince is working on that tune with another member, but you may not reap the benefits you might expect. There is less energy per gallon in ethanol, so you would need MORE fuel. I'm not sure the knock suppression will all you to put enough timing back in to make up for the overall energy loss when you get to the requirements for a FI application like yours. It would be interesting to try, though.

I was thinking for a few high passes at the track for .10 decrease or more?

I'm following all these turbo builds with great interest. Maybe a dumb question from a novice and it's already been answered.

If running out of fuel at certain higher boost/HP levels and going lean, would a V8 fuel pump deliver the goods?

IPSjeff · 05-25-2011, 02:59 PM

Ethanol will require 25% more fuel min so that won't work until the fuel upgrades are figured out. If this was a SS then you would just have to upgrade the injectors significantly and add a BAP or a twin-pump set-up and you are good-to-go.

Not an option on the V6 cars right now...

Problem iswe don't know which pump is the problem. The V8 doesn't have the high-pressure pump so we can't do a swap there. I'm not sure if the V8 in-tank pump will work with our FCM, but it might.

So maybe the v6 tank pump can't keep up with the hi-pressure pump at higher boost?

Just learning here.

That's one possibility, but it could also be that the high-pressure pump is the limiting factor. Of course, it could be both. From what I've read, our fuel system is rated for 500-550 HP (crank). It looks like we are all getting about there and starting to have issues. You can push it, but then it gets a little dangerous for the motor. I think Jeff mentioned earlier that we could pump meth in and get some more power, but I don't think any of us want to do that (should be used for safty, not become a requirement).

This will all get worked out. Several cars have run into this issue (Mazda Speed 3, Cobalt) and found a way around it. We're just going to have to take a few lessons from those builds and try to modify them for this engine. In the mean time, it's fun to have a ~400 WHP that weighs less than a SS.

Thanks for the info and all the work you guys are doing. I'm sure you'll get it worked out. V8 pump goes for $200, don't know how to get it in the tank though. lol

I read through the instructions on one of the SS upgraded pump threads and it looks like a 4-6 hr. job. That just adds to the frustration if that isn't the problem. But what the hey, at some point that pump is going to become the limiting factor if it isn't already

Fuel pressure readings taken pre and post HP pump should tell the tale.... Ya know, it might be as easy as going with a larger fuel supply line.

I don't have a gauge that will read >2000 psi, but evidently Vince can see the pressure in his logs. He's got the pressure up but it just fades at different points. You are right about the lines, and it is something we are going to try. It may simply be a volume issue and we have plenty of pressure from both pumps. Vince has widened up the injection duration as much as he can without it getting into the combustion phase.

If you can "see" the HP in the logs then it is pretty easy to rig up a "T" fitting and line w/gauge (Granger about $25) to monitor the supply pressure.

If you do a larger line, don't forget to add a high flow filter...

Thanks for the idea. BTW, I started a thread on the "Forum That Shall Remain Nameless" to get some ideas like this. Chime in if you have more.

Will do...

I'm wondering now if the V8 filter is different from ours... I.E. larger/higher flow...?
