Well i just did two street tricks with the coil and the plug gap increase and added 4 mph and over 400 rpm. The manfold isnt all about hp its gaining 50 lbs in torque below 3500 rpm according to the dyno graph they sent me. Hp and tq is the same add and what ever your applying it to will go...
So got back out with just my wife and I again back to same conditions or as close as possible anyway to the first few prop tests prior to carb coil and plugs. So 2 people 1/2 tank and moderate chop not smooth at all. 46/47 mph at 4800 rpm. I checked my plugs no signs of detonation at all and...
Sorry forgot to post last results. So last time I worked on it I put new gm 43 marine plugs gaped to .045 not factory .035 the ones I pulled the ngk were more like .030. Also cleaned and threw a edelbrock kit at the carb. Set floats and idle to 19 inches vacuum 650/700 rpm.
I also installed...
When I get other off I’ll do a direct compare on it all for everyone to see. Design wise it’s just newer better technology vrs what they ran when the iron intake was designed and then never changed for any of the newer motors. So the cast iron is truly 80s Marine technology and really built...
Boat was realy slow to get up on plane with that prop on it. If you just nailed it the prop cavatation was terrible so had to roll on it slow.
I see your point on all that for sure why I wanted to see if cleaning up some things I could get a little more rpm from this prop as its so good and...
So here is a quick shot on edelbrock. Runners are all the way up to plenum. Stock has one open larger runner no divider to the cylinder head. This design is to build more torque proven on any v8 engine combo. It’s also taller I think 2 inches so will add to peak rpm hp. It’s a proven design just...
Mine pulled fine to 5000 rpm with the 14/19p so that tiny 15p I’d hope at least that which they do say is too many rpm. Affective range is 4500-4800 rpm. Since going to a 19p 4 blade prop I’ve lost more rpm then expected. I also tried a 13.25/24p 4 blade stainless steel as on my bass boat and it...
I did think about doing the spacer but found the edelbrock intake on amazon as a return for 280 bucks vrs 350 most places so saw that as good enough deal to just give it a try.
This one I have comming is a ton different then the one I showed on the top in the pictures with the open plenum...
This thing has that thunderbolt IV on it and what I have found is a point and shoot for setting up timing. I found 8 degrees btdc if someone can verify this for me great.
So as I had posted before I just added some on the water and was alot better on my last run home for the day. i couldnt get...
I did a ton of research on the vortec heads vrs this casting number on this boat. These are not the swirl port heads that cannot flow air but the heavy duty gm castings that were marine specific. They flow way better then then the earlier castings and what I found were specific to 94/95 only...
bottom end isnt the issue at all. It screams out of the hole I am actually impressed with how fast its up on plane. It struggles with higher rpm some. Changing to this 4 blade I lost 700 rpm and seems to struggle at 4300 trying to maintain top speed. To me thats something going on up top. My...
That is one of the issues on upper rpm. I am on a hustler 4 blade 14/19 now 44 mph was only 4300 rpm where the old solis 3 blade 14/19 was 45 at 5000 rpm prop was beat up pretty bad so probably a little more slip then it should have been. Hole shot is excellent on this 4 blade was poor on the 3...
Short runner single plane iron intake. It has a slight divider not very tall. But not a true dual plane long runner made for torque and lower rpm like this motor.
I called edelbrock they claim 18 hp from the tech department. Took a 180 hp 95 down 4.3 and made 202 I guess the original intake...
Right now the holeshot is just about 3 seconds I don’t see it get any better then that. Lol it comes up so fast on this new hustler prop and lost no wot at all. But rpm is lower from 5000 rpm on the 3 blade rubex to now 4300 on this 4 blade. Same 44/45 mph depending on water conditions. So was...
