Rock Grate vs Ramp loader vs Top Loader

[396_WAYS_TO_SPIT]

Ok so I noticed a post from 67weimann. He stated that his boat picked up 4 mph when going from a ramp loader(angle iron style) to a rock grate.
Here is my question. Weimann, did you do any other changes? Did you refreshen up the pump? Did you do a tune up to the motor? Please explain to us.
396

not 4 but .4 (half a MPH)...fresh pump no tuning. Now I have a true baseline to go off of. Haven't posted anything since I want to get more data. My HEI coil took a dump on me on that trip so I don't know what really is going on.
BTW nothing was in the intake no grate or loader. It was WFO...
Now I need to put a loader in and see what happens. After, I replace the coil, I'll go and take another GPS reading with the loader.

You only gained .4 froma fresh pump:confused: I built tyros(460 jus getn it) pump this year and he went from something like 65 to 74. Here is what I did. I added my old ramp style loader(a long one), straightened the vanes in the bowl on the entrance and the exit, added a detailed impeller and shouldered ultimate wearring courtesy of (hi-tech) and squirting thunder, set the clearance to .030, detailed the suction housing and added a little speed coat. The motor hasnt been touched since new(2 seasons). Oh and the pump was built on top of a thrash can:D Thats the funniest thing. He and I were both impressed with the results.
Who did your pump weimann? What was the clearance set to? What impeller cut? What impeller brand? Not trying to bash one bit. I just want to help you;)

Yo Michael, take a chill pill. He gained .4mph by removing his loader and not running one at all. And that was baselined "ON" a rebuilt pump. He is not going to see huge gains on this boat with a worn out 327sbc.

Hey, slow down hotrod:D Ok so he already had the pump fresh. THen he did the test with/without the loader after the rebuild? My bad rod, I guess I misunderstood the post. My apologies;)

i was there too!!!!!

i was there too!!!!!
Ok and.......

[squirt'nmyload]

just stating that i was there and can verify his .4 difference....geez

.4 means absolutely nothing. Differences in water conditions, air temp, humidity, and many other things could explain that little of a difference. All those things can change in a very short period of time.

water conditions......glass
air temp....maybe 65-68
humidity.....very little
yes, i agree .4 is nothing but it wasn't slower than what he was running with the loader.

I was going to say that but my back hurts after being jumped on:D

okie dokie;)

yeah, it was nothing of a gain. But back to the "Is this Trash" thread where everyone was saying that the loader is going to help me. I took the old skool one out and didn't lose speed...so...look at it as you will but EVERY boat is different and wants different things.
Hope to get out again soon after I fix the coil issue and slap a hitch on the new whip...
And as HotRod said, it's a worn out 327 and maybe pushing 160 hp on a good day. low 50's is cool with me...

I would've been the odd ball and said I doubt just any loader would do your boat any good. There's also the thought that a boat with stock power doing 55 to 60 mph doesn't need a loader either.
