- - 500 efi upgrades (https://www.offshoreonly.com/forums/general-q/318360-500-efi-upgrades.html)

We did a 500 EFI package with Bob Madara last year that made 650 HP.

How much is a 500HP or 525HP anyways?

Forget it... I found the price... Thats crazy...

Mine were about 510 and 515

not really, that plenum wont flow much more air, heads and cam is where the power is made, if your not going to put a huffer on it.

With that plenum different heads and cam will offer very limited results. I spoke with a very irritated individual at a poker run about $20k+ upgrades to his 500efis. Dart Pro1 heads, motors hit a wall at 4500rpm. A well respected builder/tuner built and dynoed them, it was the owners opinion that they should have never made it to the boat as they hit a wall on the dyno as well. Owner also talked with sterling and they had seen similar results.

I like the 34 Viper, considering one for my next ride - whats the word with the Hull?

We like ours,look for a late 2001 or newer. (Faster hull)
