Only one guaranteed way to never tear up an engine. Do not work on one and diffently do not push one for every horsepower you can get.

Yep, never listens to anyone here, yet asks for advice, just go back and read his threads and IIRC, he had an issue with Tracy Dennis years ago too.

dyno while helpful it can also induce more wear on an engine than 10 runs. It is like everything else a tool. Hard to see N/A engine with mfi burning anything/ Heck I have thrown a big jet in one just to see if it would burn a piston/ Didn't happen. Now add the blower and yea can burn them up.

If tripple nickel did burn one up and not just hurt few rings or tweak a valve. There had to be more issues.

A few years back, I did a bunch of tests on my engine, including trying to find power by changing the pressure at which the fuel was injected into the intake. I tried low pressure big nozzles and high pressure small nozzles, in each case I was putting the same amount of fuel into the engine and in my tests, one didn't make any more power than the other. I really thought the high pressure would have made more power, but in my NA engine it didn't. I think the reason is because, over 1/2 the time, it is injecting into a closed valve. Now, I have found power in an EFI system by varying the timing of the injector.

Yea I have always wondered how you change. account for or make the closed valve part work better. EFI is the only way I know of. Although not bracket racing related. We are looking at how to keep the a/fuel car from having issues with the same thing.If think a small alky system pumps a bunch of fuel on the valve. Think about it with 40 gpm pump and 28 going into the motor with 2 .055 and one .042 to .050 nozzle setup. two of which are at the valve.

Thanks for info on finding with hi and low pressure systems.

I do not agree, on a dyno you can tell if it is detonating or hurting the motor. You monitor a bunch of variables and usually catch them before it hurts anything. you will not be so lucky on the track. You can learn so much on a dyno that will take months at the track. You are taking traction, wind, weight, track prep, gear ratios, transmission all of that out of the picture and able to look at raw data from the motor.

Darin Morgan on methanol.

Start at 55 minutes.

at 1:02 there is comment that fits a few folks here.

A lot of good info in video

Darin Morgan is NOT the guy to consult about bracket racing nor bracket cars! This is

BRACKET TALK not wanna be heads up talk

Well Eddy, this is the "Tech Talk section" of the "Bracket Talk Forum". Why do you have a problem with asking a technical question about MFI pressure running methanol?

I guess the forum owner/moderator should refer to you for the appropriate subjects in the technical section. Like only gasoline and carburetor related topics. Maybe the forum owner should make you a moderator so you can delete all the post you don't feel are appropriate and clean the place up. It should work out well for them having everything on point.

Yea, we are not a professional pipe rack racers, but my sons and I have a good time racing our car as a hobby.

If that’s the criteria used to evaluate posts, then you should never post again with your two rods kicked out of engines in two years. “Down on power” so run it again and kick the rods out, smart!!! Can’t even keep a professionally built crate engine together.

^^^I'm a Wanna-Be Bracket Racer. I was to Chicken Little to race the Numidia 150 & so was my Firechicken!^^^

and says the clueless broke dyck who's procharged POS that barely accelerates his shyt box into the 9's was broken, a no show, did not compete come the one race he talks about all year, the Spring Fling yet he never goes deep in the rounds, never sniffed a final round at this event no mind won and this shytbox hasn't been on a race track in 5 months!

The whole video referenced is about port size, volume and requirements for different induction systems. While I know little to tech for edna. How in the hell does anyone get that does not apply to a bracket race engine just because the car has a dial in?

Have you not heard? Anyone's car can identify as a bracket car if it ants to.

Now, I have found power in an EFI system by varying the timing of the injector.

Prior to switching from MFI to EFI, I ran the ECU as Data Acquisition to determine a starting point for AFR programming in EFI. Once programmed and in use, I looked at the Duty Cycle to see how well the injector size selection and fuel pressure setting was working at wot and maximum rpm. For mine it was 79% Duty Cycle with 5.30 afr programmed (methanol scale) in the very best air (-700 DA) that I’ve experienced in 2021. Last weekend it was 76% Duty Cycle with 5.20 afr programmed in 4300’ DA. From what I’ve read 80% is good “maximum” number.

You wrote that varying the injector timing could produce more HP. What effect does Duty Cycle setting have on HP, if any? What fuel pressure settings do you prefer when using EFI?

So to use your words…

“If it is not a bracket race related thread why are you here?”

AGAIN TO PISS YOU OFF EDNA. Judging from fact you can not resist reply and being a repeat like your brother mike.

It is working great. now go stomp around and scream little more then get back to us.

again, I'm just trying to help you, our illiterate redneck idiot, who admittingly is NOT a bracket racer nor has a bracket car, find the right forum

http://www.frontenginedragster...x.php/board,8.0.html


for your home built, POS, FED with MFI atop a scrap pile hemi, lit by a magneto so you stop wasting your time here a get the answers and guidance you so desperately need but I have a hunch they will laugh at you too

1st rule of helping is knowing something. Sorry you are not qualified.

Not sure how else to explain. pissing you off is just cheap entertainment.
