Super Jet More Brap

[superjetchet21]

Hey guys I have an 06 sj with as followed.. Looking for more hit I want to continue to run pump gas so I didn't go crazy with a stroker or high compression domes.

-Ada aluminum couplers -771 decked ported and polished top and bottom end
-Delta 3 v force
-Dual 44 bns
- Ada carb manifold
- lightened flywheel
- Msd enhancer
-Ada griddled head custom cut domes (175psi)
- b pipe
- tbm pump stuffer
- impros 9/16

what did the running problem end up being?

Different ski haha I share this account with my brother he's still trying to figure his out

Looks like you are pretty much maxed out. Unless you want to spend the money for more Stroke/CC's or total loss. You could also raise your compression up to 185.

i would say mag pump, bored nozzle. What is b-pip manifold diameter at? x-metal waterbox. you are pretty much maxed out though it sounds like. Play with tuning, unless its perfect now (which they never are) gains can be had with tinkering with tuning and pipe tuning temperatures.

I was going to say are you asking if you can get more grunt from your engine with this set up or telling everyone what gives you more brappery? Confusing post.

also, you can run a stroker on pump gas.

It's tuned right, chuck tuned and set up the motor for me it runs awesome just looking for more.. Like always hah. Talked to a bunch of ppl about going to a mag but they said don't waste the money if your under a 800. I heard the water box doesn't do much but make it sound louder and I'm running the blowsion tilt nozzle on it now.

as for the mag pump, i guess it depends on how you ride; its awesome in surf and it throws a more conformed jet (not sure i'd drop the money on it again). I agree that the waterbox doesn't add power, but the grunt is at least 5 horsepower on the beach.
I am in the same boat with mine, 771 JM motor with all the bells and whistles...no where to go but $10k in the hole now. IMO, you get above a 61x big bore, the next step is 900cc+, then you need a powerfactor pipe, powervalves, full spec carbs, then you need a 148+ pump by that time your neck deep. I decided to stick with the big bore, chop my hull and start going for it. I still enjoy it, and i like that i can still do a submarine to the bottom of the lake, hood tricks, turn subs and stuff like that. I can't do those tricks on most aftermarket hulls.

Sell bpipe and waterbox for 800 and pick up a pfp for about 1300. I heard pfp is a great improvement. I love mine, never rode with bpipe so I can't vouch but looks like that's the next best thing for ya

What size engine are you running it with? There are a few posts on here saying it isn't worth it unless you have a BIG engine.

781. I believe you feel the power alot more up with the big motors but if pump is right then It should work fine. I've been using a stock ware raider prop but my 9/15 just got in so we will see what that does. Pump is everything in these things to an extent so I guess if you want more bottom yiu could repitch for bottom and lose some top end power. Or if you want to feel the power more get into an AM hull and you will feel a change. Otherwise your going to be going to a bigger motor package soon if the 771 doesn't make you happy enough ha

Any guesses what the max hp these ported 771 engines are capable of with all of the bolt on's?

I know you don't want to use race gas but could always get domes set for 185 and use 93+ octane. That's how I'm set up @190psi. If you don't have 93 like me I do 5 gallons of 91 mixed with a gallon of 110 and has worked fine so far. Besides that you can:
Dual 46s?
Pfp
Mag pump

New domes and a good tune probably the cheapest and best option besides pump

I am also at 190psi running 4 gallons of 91 with 1 gallon of 100ll, and have no problems holding her WOT.

[Quinc]

Well did you figure out a way to get more brap?
