as in pre-ignition knock?

RT

 

so I've read, yes

Interestingly I compared a whipple oem tune from a while back to one from april of this year and there are a bunch of knock related changes....they are apparently still tweaking stuff....more timing w/o knock (or false knock) = more ponies....!!

Any extra noises can cause false knock possibly?

sidebar: if the bottom of the manifold was shallower, there would not be much room for air to exit the under blower I/C and airflow would be restricted.

I put a 3.3L whipple on my 03 Z06 and fabricated an under blower I/C. At the time, the whipple many was shallower and the IC to manifold clearance was a tough puzzle to solve.

so therefore one reason that the factory insulator has to get the deep six

 

enjoyed your build! keep us updated on any further mods.

 

Sorry for slow response.They dont say nothing about that foam in the instructions that I could find,seemed to me no way was it going to fit.So I left it out.

How far along are you?

 

phase 1 all installed. wideband is defective, so waiting on a new one and in the process of tuning

phase 2 cam, springs, injectors, sc pulley to follow.

 

Do you know how much room you have remaining with the injectors you have now?

 

I'll bet that he has plenty....at his current power level

 

Comp cams suggested this one for me
Keeps afm
PN 624-512-13
.572/.529 lift... 214/226 duration... 116 lsa
(Dont know about fuel lobe)

Vs LT4 cam
.492/.551 lift... 189/223 duration... 120 lsa
(Somebody here said it has larger fuel lobe)

Is the lt4 cam better for the blower on a 5.3?
Anything needed on valve train other than springs and rods?

 

My opinion is the lt4 cam is spec'd for a blower and the cam you are referencing is going to be bigger but I've always thought the min lsa on a blower cam should be 117 to avoid bleed off of boost. Also I wanted a sleeper cam that wasn't to rowdy at idle since it's my daily driver.

 

I should mention I have a 1900 maggie (couldnt pass up the price...) for my 5.3 2016. I have headers on the way (arh)
And im hunting for the right cam. Also the comp cam costs almost $500 (just the cam and phase limiter). Only aftermarket cam I can find that i dont have to do a d.o.d. delete with.

Love your setup by the way.

Whats your boost psi?
