Re: EMC 289

Years back, we played with perfomers rpm, which I believe are the same as E-street but with better parts, and vic jrs,. I liked the performer rpms pre 2003' before they changed the casting, on smaller engines. If there is something to be learned from this whole project, what it takes to make 450 hp...

Re: Artificial Intelligence to Design Lightweight Parts

Yeah, because no plane before AI designed parts ever fell out of the sky... What a silly statement, but not surprising. I’d rather not go back to when planes were less safe , louder, and slower. Are they safer or do we only hear about the problem when they crash? I have a few friends, both private ...

Re: Artificial Intelligence to Design Lightweight Parts

Just curious is that what they used to design those cracking parts on the 737NG? I still think the old slide rule dudes in the past had a better handle on stuff. Not even close to true Jet airliner fuel efficiency has nearly doubled since the 1980's Then why do they claim the ever rising ticket cos...

Sadly... made in the good old USA. I do my best to by USA whenever possible.
That should answer your question, the cost to manufacture here is so over priced that corners will be cut to compete with real world costs of production...

Very cool build, any ideas on the strange dip between 5000 and 5600?

Re: bbc oil pump on sbc iron eagle 434

Melway. I have a Moroso with bolt on 3/4 pickup. just peaked my interest is all. Wondering if anyone was doing this and feedback on how it is or was working for future reference. If I remember correctly in the 70's and 80's standard volume bbc oil pumps was popular for use on sbc race motors. Some ...

Re: Edelbrock "Air Gap" clones

It is harder to make a 2 plane manifold that performs well than it looks. Even duplicating within typical casting tolerances often involves performance setbacks that are difficult to find the reason for and fix. This holds true even when a company remakes tooling for a product they already make. Od...

Re: Edelbrock "Air Gap" clones

EMC tv did a test with 4 of them, they said the Dart and Edelbrock were USA cast, i believe in the same foundry, the Professional Products appears to be a knock off of the E AirGap but with no floor texture in the plenum, the Wiend they said was China made but it has a kicked out plenum, no notch i...

Re: Timing Curve

A cpl things that have been noted here over the years is that AFR readings and reality are rarely the same thing, I am not sure if you can gain anything from reading plugs with the exception of a wide open throttle cut, people that have taught on this subject will tell you that just driving back to ...

Re: Timing Curve

Is 25 total? I would increase initial timing until I get the highest idle vacuum at desired idle speed and then limit total to 34 and start there. To do this, I would have to reduce initial timing because idle speed was too high. This was the basis of me starting this thread. you can't reduce idle ...

Re: Camshaft duration vs valve events vs RPM

Let's say that the cubic inch and all other engine parameters stay the same and the lobe profile is the same, how much RPM will the peak power of an engine increase withh more duration? And how much increase from moving valve vents. Here is an example just on the intake lobe: 273@0.050 at 110icl. E...

Just a curious... How many out there are running BBC Moroso billet standard volume wet sump oil pumps on the iron eagle sbc blocks instead of the small block high volume billet pump? Anyone out there using the Moroso professional gerotor pump on the sbc iron eagle? Thanks! I have run stock bbc pump...
