I know you don't want to hear this , but get rid of the Pro Charger. It will be much more reliable, but not nearly as fast. I know there are lots of guys running them with sucess, but a blown motor goes through a lot of stress. I feel your pain. High performance engines and drives are expensive.

not sure of injector size or if the pick up was replaced. i would hope so between tunning and first 525 im about 30k into it not including the new 525 lol. all tunning and rigging was done by gary grimes at twister motor who from my understanding built the 900hp motor for merc and is also on the 1350 team. just to give you a back ground on the guys working on it.

should i just for go the blower?
Where in Tn are You? i will gladly bring it to you. ive read nothing but good reviews. i just need it to run with out costing me 20k everey 4 hours

as far as the lines are concerned i believe they are 1/2 or 3/4 inch. they are metal now aswell

Thanks reved up. i agree i thought i could have both with low boost but i guess not.

Sorry about your troubles, but..........the engine being blown up probably saved your life. That boat should never be powered with 700+hp and turned into a 100mph boat.

i agree, but 100 mph boat wasnt my goal. my Porsche will top out at bout 189 but ill never see that.
i wanted a 75 to 80 mph boat without having to strain and run wot all the time. that being said im worried about selling to someone who might not be as reserved.

Im in Nashville. I would love to fix it for you and have no doubt that we can make it work. No offense, but 700 hp is not exactly rocket science. Unfortunately, I couldn't do it any time in the immediate future. We are overbooked as it is. I have more than I can handle at the moment. It would be at least a month before I could even look at it.

You mentioned that you have all metal fuel lines? Are they SS braided hose, aluminum or steel tubing? IF they are hard tubing (either alum or steel), they could be contributing to the problem. You could be having at least a partial vapor lock where the fuel is starting to boil in the lines and become aerated.

First, have a look at the pickup and filter head. They need to be large enough. You also should have the fuel returning to the tank. Make sure those items are correct first, or you won't keep any of them together. Give me a shout if I can help. Good luck. I would be glad to look at it if you can wait a little while.

They are deffinitley hard tubing not ss braided hose. Could that really be my problem? could i make the supercharger reliable?
There is a return going back to the tank

A little off topic but what was the pitch of the prop and how fast was it turning when you hit 98 mph.....was that on gps ?

fixx
 

and on another note stay away from oxygenated fuels like shell 93,,it will also cause you a ton of problems..

Yes that could be part of the problem. And yes, you can absolutely make a supercharged engine as reliable as an NA engine. Us, along with quite a few builders out there, do it on a daily basis.
