Just saw proof that a 502 efi Procharged 280 on 7 lbs of boost will do 88mph GPS. Thats kinda close to 90. haha. I would NOT want to be in it even if i was behind the wheel. I dont like the way mine feels at 67.

Wish u could have gotten a video of that..that would be interesting to see

x2

Thats one dialed in 280....or the speed is a dream meter!!

I didnt see it in person. I saw a video on a buddys phone that used to be a PQ dealer. dont know details on the build or what prop size. The speedo was a digital GPS 88.1 to be exact. What it boiles down to is the guy is trying to sell me a Procharger for my boat. LOL. I must say it was very convincing!!!

Don't forget a lot of your speed is coming from your setup... Not just HP. Try a box and fiddle with your prop along with boosting... Should get results u want

i have a similar set-up - 496/whipple - running 5psi,in a laser...so far,break-in time....eagle rods,wiseco blower pistons +.030''....should be able to touch 80.....cant wait...

Throw the Arneson bravo conversion on there... Then she'd REALLY scream

I guess "TUNING" a boat is more than just about the engine. I like the deal BBLADES has where thay send you props to test so you can get the right combination.

There are several important elements in "tuning" a boat which are well beyond just the cubic inches sitting under the hatch.......
