biggest bang for your buck
 

In ya'll experiences whats the biggest bang for your buck on a merc 454?

Stick of dynamite? :stooges:

In regards to a 46' Skater? Are you going to put two on the transom, and one in each sponson?

Put a psi on it :evilb:

600 shot of nitrous?

Psi on top of a 14-71

I'd put a Turbo Encabulator on it and hang the F on:cartman:

nitromethane??

Perfect post of the year! How do you beat that comeback? Bikini thread doesn't count!!! Haha

I was really drunk the night I got 'the BIGGEST BANG' for my buck. A couple buddies have told me that it is not something I EVER want to brag about :(


.:poopoo:

OH........ on a 454....

......Please disregard the previous post:whistle:

Wow, you guys are ruthless.
To OP, what Gen 454?

Stroke it to a 496.

496...497... whatever it takes

Mag, or the 300 Hp?

I would say Heads if it has the peanut port

Sounds like your bang was a 454...lbs...

I think you guys ran him off

i think he is buisy towing a boat crosscountry.

Nope fixing up the cig that has 402s with 496s

if its a cast internal stroke it to 489/496, if its a gen 4or 5 loose the heads, if its a gen 6 the heads can do more than you might think and if its a mag boost it

I'm not a big motor guy that's why I ask. It has 420hp that is supposedly "stroked to a 496 with big port heads" as the sellers mechanic told me. I know the boat as is should run low 60's but I want to get as much out of it as I can with not going to blowers or EFI motors. I know I can pick up a few MPH with bravo's and about 1-2 mph with sanding the last 6-8' with 180 grit but I didn't know like maybe swapping the intake or carb set up would do anything big and if so like what intake and carb. Etc

Motors are from an 89 cig

That would depend entirely on how many bucks you are ready to spend.
You need to know what internals you have in them before you formulate a plan to increase hp.
If you're not tready to spend 3k an engine minimum then its a waste of $$$

He picked up the 89 Cafe Racer with a 420/TRS package in it. There are posts on it in the Cig section

Make sure you throw all the trash, corn cobs, aluminum cans, and other items out of the boat. That ought to ensure you pick up a few MPH.

man, dont yall have jobs or something? you really have too much time on your hands...

and Griff, what about upgrading a carb/intake set up?
or what drive/ratio/props could i expect to pick up a few MPH from?

Griff was telling you straight when he said 3k a side for any noticeable gains. Gonna need another 20-30hp minimum for every MPH gained not going to get that on an intake swap.

Look who has to much time on their hands.

lol it was a boring friday night, too many beers with my buddies, who hasnt haha besides the point

you wont find much performance gains from drives or props without adding hp first. these are areas that are typically tuned to a specific engine. most bigger heavy V's run 1:50 drive ratios and thats most likely what you have. props, you have to play with but B1's are a good place to start unless you have an old school deeper X dim.

good to know. thanks. dave clear your inbox about your motors

should have been fine but I just cleared a few out anyway.

Mechanic looked at it and said it had 454 stroked to 496's lol he must be able to see inside.....

The 420's already have good carbs and intakes and exhaust. Unless you want to tear the engines down, there really is not much to do.
It will take 15-20hp per engine increases to see a 1mph gain
Test the boat in the Spring and get accurate gps speeds and rpms and then talk to BBlades about having the props labbed.
You have to have good baselines before you start changing stuff.

If I'm not mistaken ,the old 420 mercs had just regular cast iron crap for exhaust. Good exhaust and a cam swap will wake up a 420. Preferably hydraulic roller with true headers

35 Cig TRS with 420's will run 60-62 if engines run good....

420's had Gil exhaust.

The 420's i have seen had giant iron castings that flowed better but weighed a ton, this boat appears to have Stainless Marine castings.

All great info. Thanks guys. I really want to do arnesons on this cause I haven't seen a cafe with surface drives before. Might be doing big motors in it but we'll see. I will be happy if I can get the boat to 65

You want to put arneson's on a 60mph boat?
