I run pump E85 99% of the time. By me it is 85 % in the summer (still 84% a week ago the last time i filled up), and usually 75% in the winter but can go down to 70%.

Alcohol doesn't have any/much lubricating properties. Gasoline does. The more gas, the more lube. The lube helps the injectors and fuel pump. I know Marvel is good, just don't know how it is with alcohol. Don't want to take any chances and find out lol. The lube below mixes well and doesn't separate in the fuel.

Most will say 60% ethanol will give you very good detonation resistance. I personally start pulling boost and timing under 70%. I'm not afraid of running 30lbs of boost on E70 (9:1 compression).

This is the lube I have been running for 15 years. It used to be around $9-10 a bottle. THANKS JOE!!! https://www.summitracing.com/parts/plu-19769-37

People also say Lucas ethanol lube works well. I was going to try that when my stock runs low.

This is the machine I have; https://www.ebay.com/itm/17476177321...BlBMUOCVz6nyYg

This machine can not be compared to the $10k machines. I have had good success with the one I posted. Just keep in mind it is designed for stock size fuel injectors. It can not keep up with larger injectors and the Fuel Pressure will drop/pulse.

Over this winter I am going to install a larger pump/lines/fuel rail/regulator. I run 210lb injectors and flow them 1 at a time right now. I am hoping I will be able to run 4 (or at least 2) at a time with the new setup. It is very interesting to see how each injector flows. The larger injectors have a much larger variance on the lower pw's. Even the $2000 matched Injector Dynamic injectors were only match at 3ms and above. I was told by Injector Dynamics if they tried to match them any lower, they would never get a matched set across the ms range. I can definitely see that when I flow them. I can make individual cylinder adjustments over rpm/load. Helps trying to even them out especially at low duty cycle.

At Bosch we evaluated dynamic flow at 2.5ms/10ms. We evaluated a statistically significant quantity of 30 and applied statistical analysis to to make assumptions on production total volumes.

We delivered less than 3% variability and also found that measurement capability and repeatability made taking that number lower quite challenging.

Densos, which had a machined main body, could beat our deep drawn body injectors by a little. I think the magnetic circuit performance was probably a variable on repeatability.

This was was for production low pressure ev14 port injectors from 15-20 years ago. Not sure where they are now. Probably nothing that did much more than 50hp/cyl size wise.

Amazing effort and fairly unparalleled attention to detail Dan, it’s been a while since I checked in. At one point you were considering selling and going to a cruiser; I think everyone is thankful you stayed on this path. I think you set the bar for the benchmark of Flatdeck restomods! Hell of a nice job. Have a good Thanksgiving.
PS, tattoos on pretty ladies make me feel kinda funny like when I use to climb the rope in gym class…

This has to be one of my favorite builds. I followed it on the Flat Decks page on facebook but there is some awesome info on here. The boat looks perfect and hitting the 100 mph milestone is awesome. Not sure if it was talked about or not but i wonder how much benefit a notched transom would get you. Although I'm sure you'd hate to cut the back of the boat up just like I would. Regardless super impressive and seems like you're enjoying the hell out of it. Congrats!

A notch is a lot work but doable. I did it to my 1985 Kevlar flat deck. There is
a thread on here called How to put a notch in a flat deck if I remember correctly. I did it a number of years age. Rick G

Rick, I miss you buddy , where you been!?

Nick, thank you , I never really put a whole lot of info on there .. Correct me if I`m wrong but the purpose of a notch is to get the drives into some clean water and to be able to raise the drives?
I`m 4' away from the transom, my drives have plenty of fresha water lol . I don`t think a notch would do much except a shorter running surface.

I think you're right about the notch and to be honest for the amount of work it would be I doubt it would be beneficial. Im just going off of what the 41 apache hull design is like. Although the one we run with staggered 1250s and #6s only runs in the low 100s maybe 110 on a good day with some chop, and thats a 6 pack boat with no real cabin. These hulls were more meant to take a beating at 90 than hit triple digits.

Hi Dan as always your ride looks amazing. When are you coming to Canada for a visit Didn’t run the flat deck this year lost my mother this
his past May and before I knew it the summer was over. Dan is right though with the sixes on those big boxes a notch would serve little benefit. Back in the hay day even most of the apaches ran number 3 or 3A drives where the notch was beneficial given little set back. I put the notch in so as to run number 5 drives without boxes. Cheers RG
