The whipple has no lag at all. It is instant power. The moment you start mashing the gas it goes.

I know it starts building boost but you arent instantly at peak boost are you? From the whipple and radix trucks Ive ridden in my observations were that the radix built full boost within 300-500rpm but it fell off up top, the whipple took about 1000-1500 with a small ass pulley to net 10#s of boost on a cammed 6.0 and carried it all the way to the shift and maintaned full boost after the shift. I imagine your boost comes on a little quicker since you are running a smaller motor and stock cam but throwing a bigger cam in there and more displacement means the charger has to breathe harder to fill the cylinders. And remember boost is a function of resistance so a bigger motor with a better flowing cam shaft has less resistance then a stock cam 5.3. Just my observation on what Ive seen and heard from first hand people.

Good purchase Zeake!!!!
Ok..now for the mods...a cam kit is definitely the first thing to do. You can pick up a custom grind Comp cam and accessories for about $699 shipped from TSP. Like I said at the top of this page--I would go with a 218/224 .563/.581 114+3 LSA.

Well I just thought my boost came on quick.

Another thought considering the LQ9 has 10 to 1 compression. Sell the whipple and buy some heads or keep the whipple.. . . . . . . .. . . Hell I am not sure.

It is a good cam and is a proven performer in his truck. The gt2-3 is similar, they definately have some weird grinds but they perform. I would keep the whipple if it was me. A set of heads isnt going make as much hp as a whipple on stock heads.

Zeake sent me a PM asking for my advice and also sent a link to this... I sent this to him before i ever made it to this link ..... I almost put a GT2-3 in my 410" motor... but i went alot bigger... I know your dont want to spend money but .... your cam choices are limited because of the whipple... huge cam will kill your boost on a big motor... RUNWALK on PT.net made the most rwhp of anyone with a whipple being 504rwhp... You could stand to put that whipple on a high compression lq9 then install a decent cam.. Dont start out with low static compression then you have to have tons of boost to make it make power... Lq9 and all the boost that whipple will make with a 218/224 or something close... Better thoughts Sell the whipple while its off and Jump on that D1sc for 2600.00 install a 228/234 cam and jump 100+ hp... best you will see with that whipple being 500s tops... I will bet only 440-460... that D1 will push you over 550 I had a whipple Cody and i think Runwalk might have made 550 but that was on Nitrous also??... I remeber 504... LQ9 is a good Choice for keeping the whipple !!.... Get a set of Pacesetters Cat less Y Pipe 550.00 I dont see a reason to waste money on 1000.00 headers/exhaust install a G2-3 spring,pushrods... and give the whipple a try... Ditch the Electronics and give the whipple another try ... After that ditch the whipple and Get a Procharger

depending how many miles are on the truck id personally just fix the head and spend the money on a set of headers.. i know the 6.0 had more potential but there isn't much improvement for the time and money hes gonna have to put into it.. he could run one more psi and make up for the difference between the 5.3 and the 6.0 or close to it. fix the head ... cam and headers and a nice tune you'll be cooking .. also think about going up to 4:10s or maybe bigger (depends what you do with the truck) 3:73's are decent ... i just went from 3:23's to 5:13's its nuts to say the least.. I have a t56 tranny though that the only reason i can go that high with the gears (.5 final drive) without slaughtering my mileage. just set it up right and you'll have to change your sig i promise

I was thinking some time next year upgrading to a Trick turbo. The whipple won't be around forever.
