Time for E85

Well, I've decided I am going to pull the trigger on this and start gathering parts together to put Big Red on E85. I have a multi-bank SCT chip so my idea is to have it tuned for regular pump gas and a separate tune for E85.

Quite frankly, I need to be spoon fed and I don't even know if this is even necessarily the best place to ask since I really don't know of too many other Mark8s that are on E85. I have figured out what pump I need but I really don't know where to look for injectors but I think I need 80# injectors? I basically at this point just have a mash of ideas in my head from 3 separate people in the community on where to start. One guy told me a single 465 pump will be sufficient with -6 line. One guy said I need teflon coated line. The other guy said I need 80# injectors.

So at this point all I know is I need -6 teflon line, a single 465 pump, and 80# injectors. If anyone can point me in the right direction on where to get what I need I would appreciate it. I was also told an Aeromotive regulator, filter, and I either need a new pump hat or re-do my basket setup in the tank.

So yeah, basically I'm clueless. BUT I have money to buy parts and I can pay someone who is not clueless like me to put it in. :eek:

I have one goal. I want to push the limits of the stock block and go as fast as I can in the 1/4 mile ON STOCK BLOCK. This is a challenge that I want to have fun with.

OK... I just don't know if the return on the investment would be practical on the limits of a stock block. You have to ask yourself how close to the limit are you willing to go?

To be honest, low 11s on stock block. Whatever it takes to get there between corn and my other weight ideas. I've seen some impressive dyno nbers on stock block cars that have held together for a long time. Some at 500+

Not to rain on your parade Kirk, but I have seen first hand stock block/head 4.6's fail - punch a hole in the block, with no prior warning at way less than 500 on the dyno - one being a low mile centrifugal supercharged Mark VIII owned by John Temple. That car had perfect numbers all the way up until it let go around 450.

My opinion, be happy with what you got and hope it stays together, or take that e85 money and spend it on building the bottom end of the motor. Good luck on whatever you decide to do!

Don't worry Mike. You're not raining on my parade as I'm sure John Temple's Centri Mark which blew up was not on E85. Not many Mark VIIIs have gone this route yet. That's why they blow up at 450rwhp. This is the exact reason why I want to go to E85. These cars can be pushed further, more safely, and run quicker than its pump gas counterpart with the same setup. There are several people I know who are familiar with this block and the crappy cast pistons and I-beams inside that have told me they were surprised I didn't go to E85 a long time ago. Now it's time. E85 is going to make this machine.

was that the same mark viii that went from tooner to tooner with terrible knock issues until it finally let go? as i remember, quite an episode.

Yes. John had a startup tune from a associate of his loaded, and brought in Ray from California to tune it. They did a plug change, and whatever else the car needed prior to tuning it. This car had a manual trans conversion. It sounded great, and from what Ray said, there was absolutely no indication from his laptop prior to it failing. John replaced that motor with a forged Terminator motor.

My car was strapped in right after John's blew up. You can see John's oil stain from his motor all over the floor in this video.

Before you do anything Kirk, figure out who and how the car will be tuned to make this all work. This is the most important thing I see missing from your plan.

We've been running low to mid 400 power levels for years on stock bottom ends. Internet hates it, but talk to people who drive those cars. All smiles.

E85 will help you definitely, but don't look for it as the ultimate fuse. It won't do that. The tune, proper fuel supply components, and extensive logging will.




Temple car was hurt before it even hit the dyno on that day. You can bet on that. Sad it happened to them, but that's what happens when you play with fire.

Sct hand held.

Maybe I'm missing something but I'm still thinking its not more HP but what your doing with what is made
I still cant understand the whole ET chase... the risk isn't worth the reward to me.

My thoughts are sct..IRS fixin....short runner intake....cams degreed...then look at the all mighty corn.

In hindsight, it is easy to blame it on a hurt motor. My take on that - What if Ray stopped at 400? Would that motor still be together today? Who knows. That said, I agree Kirk is stoking the fire.

Stoking the fire I am.

I started piecing together the fuel system and made some purchases today.

I have a 465lph walbro turbine style fuel pump, 20ft of -10PTFE line, 30ft of -8PTFE line, and an Aeromotive Pro-Series EFI #13110 regulator on the way.

Up next, rails and injectors.

One piece at a time.....

Kirk, definitely go with 80# injectors. I'm at about 470rwhp and have maxed my 60# injectors. You can probably stay on the stock fuel rails if you want. I measured 1.7 gallons per minute flowing through my entire fuel system (2 Ford GT pumps, -8 feed, -6 return)

If you have any questions, feel free to hit me up anytime.

Now that's what I'm talking about! Real life experience and real life answers. Now I have no question about the injectors.....because I was stuck between whether I needed 60s or 80s. Geez crash, it has been so long bud. I remember seeing your car at Car Craft back in 2010 and thinking to myself man, I'd love to have something like this someday and here I am! I would be very curious especially about your fuel pump setup as that has me stumped right now. I have a 465lph walbro that I recently bought but now I am reconsidering what I want to do there. I'd love to talk with you over the phone or even in person sometime about what you did. It sounds like you have a very similar setup as mine. I'd also be curious about the fuel rails as well. Injectors and rails are 2 things that I have not purchased yet. I lost contacts on my old phone so you should PM me and give me your number. :)
