Re: Radical/Ground Breaking Builds ?

I mean, considering how the oil industry is subsidized here and overseas by their respective governments, I don’t think the argument has merit considering we’re likely not paying the real unsubsidized price for a gallon of oil or gasoline. Also, let’s be frank, cars exist entirely because of the ro...

Re: Performance improvement from reducing rod journal size

2.100" journal - Circumference = 6.597" - Square Area = 3.464"^2 1.889" journal - Circumference = 5.938" ( -9.9% ) - Square Area = 2.806"^2 ( -19.0% ) I imagine near 20% of the journal's mass is a pretty significant weight reduction (relatively speaking). It may be more when accounting for oil passa...

Re: Performance improvement from reducing rod journal size

We tested this way back when, before piston guided rods and even smaller rod journals became common. SBC, small journal crank was worth 6 hp over large journal. Honda size rod bearings were worth an additional 4-5 hp. What was the build? Are we talking 6 hp on a 700+hp NA small block turning 8000+ ...

Re: Radical/Ground Breaking Builds ?

Haha a good cam will blow you away and be tame. Of course. That's not the point. So what is? The only problem I see is the cam. I know what you said Butttt :D To see how far I can push bolt-on parts without opening up the engine. The current "bolt-on" record for this engine is 11.41 @ 116 mph. I'm ...

Re: Radical/Ground Breaking Builds ?

I'm doing something somewhat different. I'm trying to go low 11s but without a cam. Trying to see how quick I can go with a Gen 2 LT1 5.7L with a stock 160k mile bottom end, stock compression, stock cam, stock heads, and stock intake manifold in a '93 Camaro. The AC, PS, and alternator are deleted ...

Re: Burst oil filter,22re

Can you get pictures of the failed filter? Fram went through a rather major rebuilding after they were acquired by Rank. I've cut open 65 of them in the past 5 years, from dirt late models to truckers going 100k mile OCIs, and not a single failure found with them. Purolator has been the problem bran...

Re: Used Oil Analysis, 5 year old oil in a KA24E

I have considered a header for it. I just don't know how useful it would be as this engine will rarely see over 3000 rpm.

Used Oil Analysis, 5 year old oil in a KA24E

Earlier this year, I decided to pull my grandfather's old Nissan pickup out of the barn and start restoring it. It had been sitting in that barn since he passed away in March of 2016. Out of curiosity, I decided to sample the old oil that had been sitting in it all of those years. I have no idea wha...

Maybe concentrate enough of them near the counterweights and actually help rev acceleration like a magnetic pendulum. :lol:

Magnets from old SATA hard drives works well also.

Re: Magnet on oil pan?

It's a good idea but note that it will only catch ferrous metals. Bearing material, typically made of lead, copper, and aluminum, will typically pass right by it. I say this because some people will hear a rod knock, look at the magnetic drain plug, and think it must be fine since there isn't much m...

Re: Lowering octane

I tested the mpg thing with my wife's 2012 Mustang V6 3.7L without her knowing it. I'm always the one to fill it up. I checked the mpg of her commute over 5 tanks of 87, and again over 5 tanks of 93. The averages were 0.2 off with the favor going to the 87, which is well within a margin of error. Th...

Re: Sunoco EXO2 Fuel

A fuel recommendation cannot be made from the information provided. Your hardware list contains no useful data. What is needed is data relating to inlet air temperatures, IVC, inlet pressures, timing curves, torque curves, etc. And weather conditions. In the absence of the needed data, almost any 1...

Re: Sunoco EXO2 Fuel

I'm interested in knowing more about this fuel. There's a place somewhat local to me that has it. According to the Sunoco rep I spoke to, it contains both methanol and ethanol. Octane (R+M)/2 = 107 Research Octane = 114 Motor Octane = 100 Specific Gravity = 0.750 RVP = 7.3 psi 10% = 139*F 50% = 160...
