Re: Superbabi !! Heres your pics of your Y2K
 

Johnny, he put the 496/375 HP in her, top speed about 68 mph. Bottom line................it's still a Y2K !!!!!

Re: Superbabi !! Heres your pics of your Y2K
 

:D :D :cool: :cool: :cool: Still faster than the avanti!! :D

Re: Superbabi !! Heres your pics of your Y2K
 

Got the new 29" B1 Labbed 4 blade on this weekend, only got 10 mins on the prop when RAIN RAIN RAIN came, we will see what numbers I come in with next weekend.

Re: Superbabi !! Heres your pics of your Y2K
 

:cool: :cool: :cool: Lez see her SCREAMIN!!!

Re: Superbabi !! Heres your pics of your Y2K
 

Who labbed it Gary?

Re: Superbabi !! Heres your pics of your Y2K
 

Tom, this was done by Merc. Racing Props. I will send the 5 blade 27" maximus back to Merc. Racing for a little tweaking. She needs 100-125 RPM'S more to the Rev limiter.

Re: Superbabi !! Heres your pics of your Y2K
 

how much is she truning right now and where the rev limiter

Re: Superbabi !! Heres your pics of your Y2K
 

4 blade is at 5240 rpm's. The 5 blade is at 5150. The limiter is at 5275-5300.

Re: Superbabi !! Heres your pics of your Y2K
 

hmmmmm... You could push that motor to 5500. 502 right?

Re: Superbabi !! Heres your pics of your Y2K
 

Not sure ??

Re: Superbabi !! Heres your pics of your Y2K
 

I dont think the rev limiter from merc is adjustable... You would have to reprogram the computer to bump it up.

Re: Superbabi !! Heres your pics of your Y2K
 

Hi Gary,

Mercury topically sets the rev limiter 150 to 200rpm higher than the maximum recommended rpm for a given engine.
The max recommended rpm for your engine is 5200rpm correct? Likely the rev limiter is set at 5350rpm... :cool:

Yes, the components used to build the 600 would likely work without failure to 5500-5600rpm. It is a bit more complicated than just changing the rev limiter in the computer though. The fuel mapping would also need to be changed to allow for the proper mixture at high rpm or the engine would run lean.
Another thing to consider are the valve-train components used. Even if you did spin the engine faster, would it actually make more power? Probably not, because the cam shaft used was likely designed to make peek HP at around 5200rpm in this 502 cube engine... :cool:

I maintain that the best way to get more HP out of your 600 is to turn up the boost... :D

From speaking with different prop gurus, I would say prop your boat to reach 5200-5300rpm with a vary light load. And I would define a vary light load as 1 person and 10 gal. of gas... :drink:

Re: Superbabi !! Heres your pics of your Y2K
 

yes we would have to mess with the map but we have the mefi stuff to do it and a lot of performance shops do.

Re: Superbabi !! Heres your pics of your Y2K
 

My thoughts also Pat !!!!!! :D

Re: Superbabi !! Heres your pics of your Y2K
 

BOOST=FRIEND!!! :D

Re: Superbabi !! Heres your pics of your Y2K
 

Boost up to 700-800 and the NXT-1 drive. :D :evilb:

Re: Superbabi !! Heres your pics of your Y2K
 

:evilb: The only issue with mucha boost (other than getting an nxt1 drive :rolleyes: )is no more running hard on pump gas. :( You can stay out of boost and run on 87-89 but for boost at 7-9lbs you need octane in the 90's. :( :rolleyes: :chick:

Re: Superbabi !! Heres your pics of your Y2K
 

What octane would I need ??? I am using 93 with the 600 sci.

Re: Superbabi !! Heres your pics of your Y2K
 

Hey Gary,

Has anyone cracked the code on the 600's computer yet?
Well, I guess what I'm asking, is there a reasonable upgrade for the 600 yet?

I know you like Merc Racing stuff but I believe Maxwort and Bmax have Bravo mods that will handle 750-800HP. Got to be a lot less $$ than the new Merc drive and you can get one. Go to the Bravo Shop web page, I think they will even warranty their modified Bravo drive for 750-800HP.

Re: Superbabi !! Heres your pics of your Y2K
 

Your octane is fine. You just need timing control.

Re: Superbabi !! Heres your pics of your Y2K
 

Pat all lips are sealed with reguards to the 600sci up grades for boost. :( I may have to go to plan " B " :D

Re: Superbabi !! Heres your pics of your Y2K
 

Quad Rotor? 5.0 liter? :D

Re: Superbabi !! Heres your pics of your Y2K
 

Johnny, what ever it takes to get to 100 MPH !!!!!!! Are you guys racing in PP on the 25 th ???????

Re: Superbabi !! Heres your pics of your Y2K
 

We hope soo!! :cool: Going to try anyway...

Re: Superbabi !! Heres your pics of your Y2K
 

I checked over on the Whipple web page yesterday and they don't advertize anything for the Merc 600sci as of yet.
There will be something out there soon enough... :cool:

Re: Superbabi !! Heres your pics of your Y2K
 

I may have to exerise another option !!!!! :D

Re: Superbabi !! Heres your pics of your Y2K
 

we talk to dustin everyday and ask a lot i would let you guys no if there was :D

Re: Superbabi !! Heres your pics of your Y2K
 

SuperGary !!!
Finally got a few minutes to get on the puter.
What would happen if you got hold of a whipple ecu for a 502?? would it make 750 HP ???

Re: Superbabi !! Heres your pics of your Y2K
 

Rick, how you doiing ???? As I understand if you put the whipple on the 502 with full boost she should make 750-800 hp. If all goes well the rest of this year ( $$$$ ) there may be a new project for next year. !!!!!!

Re: Superbabi !! Heres your pics of your Y2K
 

Be easy on the hp (750) with a stock gm 502. :cool:

Re: Superbabi !! Heres your pics of your Y2K
 

As I understand the Power Upgrades from Whipple charging Merc 502cube engines with 5-6lbs of boost...

415HP/502Mag + Whipple = 650HP
500HP/502EFI + Whipple = 700+HP
525HP/502EFI + Whipple = 750HP

Now these start out life as 8.7:1 compression base engines.

The Merc 600SCI starts out with dished pistons and 7.5:1 compression.
I would guess the boost would have to be increased to 8-9lbs for the base 600SCI engine to make 700+HP.

Re: Superbabi !! Heres your pics of your Y2K
 

We have our whip hp500 making 750... tops with 7lbs boost. Thats about right for a 600sci...
