New to E85. Few questions

[KevinB]

It was nice to get out in the car. We all had fun, at least I did

The roll bar padding is coming. Just got the bar in there. I couldn't say no to them when they wanted to go. Hell, the 2 older kids are dare devils on their bikes, so this wasn't as dangerous ...at least that's what I told myself. My wife would have had me pay the dental bill out of my race money..will definitely get that taken care of bc we plan to use the car more often now.

Here is my last run. Launched too hard and spun. Sounds good on the top end though. Don't mind the major red light, running the pro tree has really messed up my sportsmen tree skills.

What are your plans for a converter?

Bad ass Kev- Very Glad to see the MPH with your fuel system as is. I think I owe someone a "I told you so" (not you)

Thanks! Its cool to see what the stock lines can do. A friend that is going to run his Buick on corn when its together is going to lend me his 160s. Then we will see what is the limiting factor right now. I need to put my 275s back on and run a low ten. These small tires are killing me.

I'm saving up right now for one

You should be able to run a lot faster than a low 10... But then again you say the converter is slipping and the fuel setup not 100% done yet, you have a few factors that leave questions in the air...

Do you and your crew all use similar A/F ratios? Is there a target change with aluminum head motors vs iron head combos in the experiments you guys have ran?

I'm going to send you a pm with some questions. Right now I'm sick in bed for whatever reason. Sucks! But when my head is clear of medicine I have a few questions.

I'm curious too. I hear a million different things from people here locally but all of them have different cars. One guy has a high 9 second evo using stock lines and 2 255''s. He says he runs 12.0:1! Holy crap! Another local tuner that is big into nitrous and turbo mustangs says he runs everything rich and with a boat load of timing. So far running below 10.9:1 for me makes the car lay down up top. 11.4:1 makes it scream. I haven't tried the rich with timing yet though. I'd be curious to see what the 10-9 second v6 buicks are running.

Are you thinking of trying e85 out Jason?

 

[TurboBuick86]

I have iron heads on my car and ran my best (which was a 6.75 and 104.2 mph, not the 103 mph I currently have in my sig, on a hot Miami day ) with the a/f as lean as 12.8 with only 55 psi of fuel pressure which sucked ass. Seems like e85 works better with a lil bit of timing and 11.0-11.5 a/f or even richer.

Yes for sure! I have played around with a 50/50 mix and ran it straight, but with 75lb injectors it didnt allow me to reach my normal boost levels a while back. I have been watching this section, local members, You, and the guys around Gabby R. to learn as much as I can.

Thanks! I look forward to more sucessful passes from you and your crew. Thanks to all the E85 users for sharing!

I'm glad these cars are still going hard and there's still competition out there from all of us, which in turn pushes all of us to make ourselves faster and faster! Even the way the economy is we still find ways to go go fast, thank god for this wonderful corn fuel!! Us down here in Miami are just beginning to get the cars dialed in with this fuel setup

 

[KevinB]

OK, I think I am definitely at a fuel supply problem. Pulled all the plugs. #3 showed some detonation and #1 showed a little more. Being the last 2 cylinders to get fuel, I'm thinking its a supply issue rather than injector issue. I have a -10 feed, probably going to start to install that here soon and use the stock feed as a return. Got a billet k&n fuel filter I was given, but it's a 10 micron which is probably too small. I'm also going to figure out a better fuel pump setup then what I got. It's a homemade double pumper and the 2nd pump t's into the primary pump. I don't like the way it t's in, but I made it using stuff from the local hardware store. The car is down for the moment. Sending the torque converter out to get tightened up.

Pick up a fuel pressure transducer for the fuel rail. No more questions about the quality of the fuel supply then.

I don't have a data logger to use with it though.

Here's what I'm working on now. My homemade double pumper. I was never too excited about the way I t'd the 2nd pump. I'm going to try to find a better way while I wait for my converter to come back

 

[KevinB]

I installed some 160# injectors. For the double pumper, I'm replacing one of the pumps. It was an old reds pump made from an old GM pump. Putting in a gs307 with the relief pushed in. When the converter comes back, I will see if I can go further. I'm holding off on installing the -10 feed for now. By the time I buy a filter and some fitting, I will be way over budget.

Were you able to data log the pass? I'm headed with a dp setup as well with 120's through stock lines and would think its plenty of pump/supply?

Your testing is providing some great info and will help out once my rig is back up and running.

I am told a 9.9 and double pumpers with stock lines is possible

Kevin, there's an easy way to guarantee lower IDC on your current setup, upgrading your feed fuel line. You can add 200lb injectors, there's still a bottleneck which is not maximizing your current dual pump setup, the stock lines (I believe you upgraded the rails, forgot). This will save you the most $ and time, might've gotten away with your old injectors.

Have you and Cliff seen BEATAV8's thread about IDC issues he was having?
Shows what happens with rail volume restrictions and huge injectors feeding off the rail. No water, no drink.

Slap on the #10 and consider it insurance for your investment and time enjoying the car. :wink:
