Jetting with innercooler
 

Hey guys i am going to be adding a innercooler, it is a 1071 blower. Does this change the jetting big time or not? The water will come from the nose cone so when i am not moving it will not see any cold water. One other thing dont think i have room under hood scoop. Do they make taller scoops or just take scoop off? OR???

Thank you for your help!!

Depends on what kind of scoop you have now. The water from nosecone is good, you dont want anywater at idle. Be sure to put a PSI relief valve on the chiller, you don't want too much psi in it. As for the Jetting, I can't say for sure. If you are upping the boost, you may need to step it up.

Thank you very much i am at 10PSI right now with no chiller. So i dont think i will go up any. So same boost jetting can be close?

A cooler intake charge puts more air molecules into the mix. It will lean out some. Your boost pressures may actually go down 1-2 pounds as well

You think at idle much will change? Idle air mix screw and pump shot?

Thank you Skydog

Idle should not be affected. Might just need some small idle air bleed adjustments.
You will probably have to richen up the jetting a couple sizes, but that depends on how rich it is set up now. If its on the rich side now, you could be fine without any changes.

Thank you for all your help guys! I am running 10PSI u think it would be a very smart idea to add one?

At 10 psi, I would definately add one. If hatch clearance is an issue, you may want to consider a Whipple innercooler. They only add about an inch, but cost quite a bit more.

10 4 buddy i will for sure then! The scoop is a problem, i will look at the whipple cooler!

THANK YOU !!!!!!!!! :) :) P.S. Motor getting torn down right now i think it might be some DETO....But not bad.. i hope... wrist pin??...... power good ...oil psi... valve train all good has alittle clater at idle... Will know real soon.

What mild thunder was refering to..

when you install a inter cooler you have to plump water through it,,you ill want to install low watrer picp ups on the back of the boat to feed the coolers..at the same time you dont want water going through the coolers at adle on efi engines which will make the injectors puddle and you will have a rich condition, also you will need to install a pressure relief valve so you dont blow the inter coolers with too much water pressure,skipping waver will blow the coolers without a pressure reliev valve..15 psi is a safe number for the coolers..

i see your in ill,,contact VFN fiberglass in addison for taller scoops ,if their too tall you may have to go arizona style and leave them off..

Yup got it. It will work great i have a low water pick up on my nose cone going to use.

Thank you U

WOW Wipple looks nice and i bet 1" will work!!! Now does there cooler work as good as the 3" coolers? Not sure with 3 times less surface area?

THANK YOU

i dont like using the ones on the drives,,they are to low and if you get stuck by accident in sand or mud it will plugthe coolers..sorry i failed to mention,,you will also need to install a pair of sea strainers for the coolers to prevent this from happening..their is also a port in the strainer you can plumb the relief valve into then to a hose and to a through hull fitting that you can see while on plane so you can see their working..

Yes i understand buddy. Wow this could be 5gs real fast....:lolhit::lolhit: I wanted to use the drive with a relief valve plumb in to that......but u think no go.:party-smiley-004:

Talked to Dustin at whipple sounds like nose cone is a good feed for there innercooler. I was looking at pics of whipple cooler does it come with intake too?

Thank-you

Yep, they are a combined innercooler and intake manifold. They will cool at least as good and probably better than the standard 3-4" chillers.
They cost more, but if it keeps you from having to modify your hatch, it will be worth it.

10 4 buddy thank u looks like I will go with the whipple. Like u said should drop boost to about 8.5 or so then we will turn the over drive up to get back to about 11.5 boost. That should be a great HP jump!!! Hahaha what is best way to up boost bottom pulley or top? And is there a chart to look at to know about what gear to go with to gain about 4 psi.

I don't know of any charts. The change in boost is also related to CI of the engine. A bigger CI engine, like your yours, will need more of a pulley change than if the same blower was on a 502 to gain the same increase in boost pressure.
Changing only the top pulley will be less $$$ if you can get the ratio right to make the amount of boost that you want.

Thank u for all the help will let u know HP and vid of her on dyno!!!

Sky dog if ya need some help I can give you some help we been through it all on this boat. I would run a thru hull pick up for the motor to with a pop of youncan get here in town not the crazy money they ask for marine they are the same thing. Shoot me a pm some time can shoot you ton the right people whomare running same setups plus I'd like to see this 130 mph run.

Stick that nose cone once in the mud and run hard you will melt her down.

Will do buddy, going to put a sea strainer on the line going to inner cooler. And will be super carefull not to get nose cone in the mud!! We are going with a soild roller cam,shaft rockers, now to get hp to 1100-1150 on pump. As far as water pic ups go, yes i am dieing to know/see some pics of the best set up to get good soild water to the beast!!

Thank you Skydog

We ran jessel but if you need i have billet girdles for the rockers.brand new never used. We broke a rocker stud once and said the heck with it.
