280 what super charger to buy?
 

Im looking at whipple or pro charger.are they worth the money and will i see big 15 mph they claim.

What engine do you have, the 502 whippled will get 700+hp

I have the 496 ho with 80hrs on it

wipple,wipple :cool-smiley-011:

Well, the 496 ho will need some work before the charger is installed, crank / rods / pistons and might as well slap some AFR heads on there. To bad you don't have a 502 and just install a whipple on there. You can put a whipple on a 496 like it is but a matter of time and you will be replacing some parts. Raylar make a kit to run the whipple. http://www.raylarengine.com/

looked at raylar heads that was on a gm 8.1 at a machine shop,cant beleave the junk they are,there not even worth scrap,the guy that owns them put a ton of money in them after he bought them and raylar did nothing for him,springs,rockers,valves,sends head bolts with just plain flat washers,whats with that,

I know a couple of guys that have put superchargers on stock 496s with good success; 1 Whipple and 1 Procharger.
From what I’ve read, the internals of the 496/8.1L are good for about 600HP but the pistons are casts not forged. You definitely need to change the head gaskets and the fuel mixture had better be right or the engine will melt down quickly.
For me the 3.5PSI kit from Procharger is the best bang for the $$ on these engines. You’ll gain 100-125HP so probably 8-10mph.
No way I’d put more than 5psi to a stock 496/8.1L; that would be a ticking time bomb.
I have not read much negative about Raylar prior to your post.

Me neither. I gotta feeling we'll be hearing from Ray soon. :party-smiley-004:

I think wipple can help with re-mapping your ECM .Supposed to be ok with a base engine if you don't get to aggressive with the boost levels . Good Luck :cool-smiley-011:

pull the 496 and put it in the corner to go back in if you sell the boat and find a 502 or get a motor built that has the parts in it that will hold up under a blower. then get a whipple and hang on. with a good motor and heads and a 3.3 liter whipple you can make from 700 to 1100 hp trust me look at my avatar

Save your mony use the boat and enjoy it!! Once you screw with it, you always will. Leave it stock. Trust me Im on my 3rd 390 I learned the hard way. Once you **** with it and you want to run it something will brake. I had the blower boats and had nothing but head aches. Do you have hyd. str. and tabes. something you should have with any more than 400 hp.

I'm not used to someone giving good advice on here.:drink:

The more i here i think i will leave it alone,yes it has tabs and hyd steering

Hey, No one mentioned fuel. I was going the way of a 871 with 2 carbs, I turned back when I relized that the 1.8 mpg at 55mph would drop by 1/2.

my 80 gallon range is about 130 miles. It wouldn't be with a blower.

Hey ask Hyper about it if you don't believe me.

Come on guys, half the fun of this sight is helping someone else spend there money...:drink:
I am actually in agreement that you should leave the engine stock so long as it is running well. I too have learned the hard way that modifying a stock engine can, and in most cases, does lead to frustration. The only "add on" that just about always works out is a good aftermarket exhaust system, but the gains are minimal.
I’m running a basically stock 502MagMPI with Stainless Marine exhaust and have been able to resisted to date the erg to swap the cam, heads, and intake for the 500EFI stuff I have sitting on the shelf.
If you have the expendable cash and a real need for more speed, the advice to build another engine up to the task, is the way to go...:cool:

Why Pat, "whatever do you mean?"

Id say whipple to the question. Also blower motors are a kick in the n*ts. Both of mine have been blower motors. But i can tell you this the power is well worth it. Im happy with my 10-71 blown. I had a lot of help from MikeS so keep that in mind toy.

As far as cutting your MPG don't believe everything you hear, if you drive them the same way it will not be that much different. Besides you will be able to cruse at the same speed as before with less RPMs. More HP= larger pitch prop. This is mine.

Just my .02

What good would that do? Hyper doesn't know his range. :D :D :D




Some things you just never live down!

Tom has good advise , if you have big power be prepared to pay more and boat less . I have had an expensive education on that .Stock is nice , but I know I hear voices !!! :evilb:

I have blown up and tore up more zhit than most people. Call Steve S. he will say the same thing. ( As for as me tearing stuff up I DID NOT BLOW THE TRANS ON THE BIRD BOAT!!!) Save your money and trade up. Kenny just got hold of a 05 290 sc with a 525. He wants to move it.

I have to say I am giving my engines the best chance in the world not to break.

VV i know where ur coming from

If I could just keep them on the engine stands I'd be OK.:ernaehrung004:

Yup its the safest place because behind my arm its a problem

they last longer if you play nice ! :angry-smiley-044: and don't beat on them to much :cool-smiley-011:

I be glad when I grow up to be like you:doggy::drool::
