On a weekday!

Re: Twin Whippled Smallblock Y2K
 

How many hours do you think can be expected out of a 6.2 (377ci.) compared to a monster Blown BB ???

Re: Twin Whippled Smallblock Y2K
 

Whipple claims that adding their system does not change the longevity of an engine. Now I gotta think that is BS, but even if it cut the life in half.
So 200-250 hours for a Whippled 320HP/6.2L Merc.
I would guess a 1000HP supercharged BB could last the same if it's built right.
The question I'd be asking is how much $$ either way?
Whippled Merc 6.2s would be around 20K each.
1000HP BBC ???

Well our 1300 was 50k in 1999 so its somewhere around there now.

Re: Twin Whippled Smallblock Y2K
 

Pat all you say is so true :D but we all know the WEAK LINK. I really like the XR on the 6.2.................Like a # 6 on a 700= BULLETPROOF !!!!

Re: Twin Whippled Smallblock Y2K
 

Pat,
I would think that the life span of a 6.2 is alot longer then 400 hrs. Afterall, it comes with a 6 year warranty. The duty cycle of the Merc. 600sci is 400 hrs. That was told to me by Scott, the Merc Racing rep. And that has a 1 year warranty.

Re: Twin Whippled Smallblock Y2K
 

Rick, I wonder how they ( merc...who ever, the industry ) figure the average yearly hours ??? I have heard any where's from 50 to 100 per year ??????

Re: Twin Whippled Smallblock Y2K
 

Marine engines really need proper matinence to live there duty cycle. I haven't seen too many factory engines that made it 400+ hrs trouble free, I would think that warrenty gets used more then not. Quoting the article in Powerboat on the 1500 sterling 50-200 hrs before rebuild depending on how its abused... I mean used ;)

Most of the 500's that got a whipples slaped on them lasted about to the 200hr mark before rebuild w/ normal boost. The motors I have seen and builders I have talked to kinda agree that a motor built for supercharging from scratch will last longer then a stocker w/ a kit.... but It all comes down to how you use it and your matinence schedule.
