Steve Brule, sharp guy

Brule has worked at Westech Dyno for seemingly for ever, The Hot Rod and etc msgaxines had used them for long time too. Freiburger worked for thise mags seemingly forever too.

Anyone know of Brules race boat motor building?

The Engine Masters TV series started as a magazine story which became an annual event.

I think in Popular Hot Rodding.

Then its own magazine series.

Was very cool.

Each yr they devised new rules for the season.

I.e., OE iron small blocks, any head, any cam, sgl 4 brl NA.

Anyone could enter.
Saw some cool packages.

Now morphed into the TV show.

Tons of history in that dyno cell.

I just never heard of Brule, or his race boat motor building until seeing him on TV.

The other guys have been around forever.

Very sharp dude.

I believe that to be true,in my collection of 500/525 intakes , one has ribs on top plenum and am pretty sure that is the version aszm personally sold. But the upper normally has a divider and lower divider goes up square to meet the upper, this picture I found off a modified 500 efi lower actually ever being marketed, modified is first Ive seen and I been chasing these mods for quite a while. heres a stock one vs one i modified

stock intake

one i modified

Brule is the brains behind all of that. Incredibly smart guy when it comes to tuning.
Freiburger just retired from the magazines after 30 years.

Our finished 525 throttle body.

Spacer to extend throttle body out to help #1 short radius.

525 liwer ported.

Lower with big injectors installed.

525 stock throttle body.

525 intake top with stock plate cut off.

We were able to achieve 700 hp, 700 lb ft. With these intakes.
565 cu in. 9.3 comp. But they were done. Came to the conclusion it would be much better and cheaper to just have intakes made to what we wanted. The nice thing about sheetmetal intakes is you start with a clean sheet of paper.

This thread has certainly peaked my interest. I have warmed up 500efi's, making 625hp. Aluminum Promax heads, 509ci, cam, bigger injectors and porting to intakes. Wonder if theres any gains left on the table with a tunnel intake? Kwright, really dig your build and read your resto thread in fountain section, well done.

Agreed, eventually you hit a wall and it becomes futile, but none the less you're still 100 hp up from where you started. good thing for boats is they make a ton of down low tq..

Probably some but NA 509’s your nearing full potential (within reason) unless you were gonna turn it 6k plus. Where did you peak with current builds/mods? I’m sure many would disagree however I’d target in on stroking them. Then at least you knew going into it you’d see a 75 hp gain min without spending a bunch more money. Just a guess but cost of the tunnels PLUS some costly porting$$$. Could probably stroke for under 3k a side.
