Fuel injector testing and cleaning
 

Well, that's not good :eek:

Well it looks like you are good to go after cleaning.

Sure are. Since I don't know crap about fuel injectors, I wonder if those low flow rates contributed to my motor blowing? And, I wonder why injector #4 was wide open? Was it stuck wide open?

That was my first thought as well!

That wasn't a lot of miles either. Pump e85 is hard on injectors. I guess I'm going to need to run a tank of pump gas through it more often

Yep, pump e85 can be rough on injectors and fuel pumps. I just received a barrel Sunoco e85-r which is race e85 so it should be pretty clean.

Definitely the way to go. I have Seb on the line right now. I'm going to go over the results with him

That's what got you. Did you have the injectors cleaned before you started using them again? That was one of my worst fears. I had mine cleaned and tested when they put my new motor in. They also drained the tank of the pump E85 in it.

Nope, I didn't. Big mistake. If the one injector that was wide open was stuck wide open, it could have hydrolocked the motor also. Under boost with both fuel pumps going, that's a lot of fuel being dumped into the cylinder. I'll also have the old e85 drained this next go round. It looks like I will probably be going with the stage (Seb) turbos :icon17: instead of the stage 1. Unfortunately, they won't be available until August/September so my cars going to sit a few more months.

See about installing an Injector Dynamic's ID-750 fuel filter. I have one. My injectors were good to go. I attribute it to the fuel filter.

Watch this again. It was posted in my thread.

Good idea, I'll talk to Seb about it

I like that filter. Seb really likes it too. There will definitely be one going on my car. Thanks for the tip :tiphat:

Another great video.

Definitely a great video

Sounds like the guy on Instagram works on diesel trucks. That's a whole new animal. Common rail diesels run a max of 20 to 24,000 psi of rail pressure to feed the injectors.

Yep, he was making the comparison to the diesel trucks he works on

How often did you flush the fuel system with a tank of just gas? Thinking of running ethanol later this summer and rather not constantly pull injectors to get them cleaned. Hoping running gas occasionally will prevent problems.

I only ran one tank of gas in 7k miles. The rest was on pump E85. Run a proper filter and it is not a problem as long as the car is used regularly. If the car is going to sit for several months, pickle the fuel system with Gas.

I only use top tier. Ethanol free typically. It really does, no-**** matter.

I run e85 99% of the time

Makes sense given your tune. Funny thing is when E85 came out, lotta dudes were saying their tear downs were SUPER CLEAN and had pictures and all.

My tuner suggests after a few tanks of e85 to run a tank of pump gas. I think my issue might have been that my car being down for 6 months and then driving it to burn all the e85 out of it to get it ready for tuning purposes. Spooler mentions it in his post.

My car sat for about six months with a tank of e85 in it while I was doing my blower conversion. I then drove it to drain the tank so I could put some 91 in it for my new tune. That tank of e85 might have gone bad. I'm not sure though.

That was your down fall. Sitting with E85 in the tank is not good. Mine sat for a while hence why I had the tank drained and the injectors cleaned just to be safe. I didn't want to damage a brand new engine. The fuel filter keep all the junk out.

They are very clean. I have my old pistons and rods.

And my car's sitting with e85 in it again. I'll make sure Seb has it drained and flushed if necessary. I'm definitely buying the Injector Dynamics filter you recommend
