How do you like your wynjammer s/c? Does it amount to much?

I ran a 16.3 with my 4.3l truck before my tune-up. Since then I have added the bored tb with thinned butterfly, CAI tuned MAF sensor, K&N CAI, underdrive pulley and alternator pulley. I'm curious what it'll do with those add-ons. I'm hoping for at least 15s

that looks tough lol

i like the wynjammer, it boosts about 6 psi i think there buildin a enw pulley for more boost it should be out by summer.. but it helped alot lol i just dont know how much time wise cause the tracks are closed.

I was a bit curious about the wynjammer. I hear that system shreds belts. With such a small pulley to get that compressor speed high puts a hard load on the belt.

i shredded one last nite thanx for the jynx lol.. jus messin but i have 1500 miles on it and thats the first.. i would think it should last longer.. i've talked to quite a few guys runnin wynjammers and they havn't had a problem with it.

No Pics but I have an adjustable reg that came with my TBI from XtremeFI... I'll sell you. Never used it.

They havent credited my core charge yet with ticks me off... I must admit... but anyway- if you want to buy the thing- make me an offer.

hi there the power charger..is that the one that looks like a salad bowl(i couldnt open the pic) if so i have one from jegs and it works too well. it improved air flow so much my 350 vortec was running lean. i also had the thicker injector pod gasket and i inch spacer. i put everything back to stock for now so i could run the proper mix. i will have to modify my fpr to make it adjustable for more fuel....by the way..does anyone know what side to put a fpr gauge??inlet or return side...thanks//lzrd

I want that External AFPR setup

[GreaseDog]

im getting ready to do it to mine, completely replumbing the entire system from the tank forward in braided stainless, and adding the Aeromotive AFPR, is cheaper than buying a set of prebent stainless lines

Newbie - can anyone help me find a link to the "free" tbi mods?

I have a 1995 5.7 TBI - that'd I'd like to get a little more out of while towing my camper this summer.

Thanks!

I looked at a few and most led to dead links. Others are posts that are 5 years old and they are missing pictures and stuff. Is there a place where it is stated and locked and kept updated? Like tech pages or mod pages whereit's just info kinda like this site?

Thanks in advance for the help!

With this would you need a tune as well or can you put the cam in and be fine...Its for a 91' Chevy with the 350

[92SierraTBI]

you will need to tune

What I did tonight



With the rough work done


One side finished. There's a small ridge left, but it's under a thou so I think I should be alright.

[GreaseDog]

looks good. are you going to smooth the radius inside the bore too?
