Can i get the same results if i port the stock TB? or should i just skip the hassel and buy a new one?

 

You can have people port them out to 52 or 58mm, and essentially it is the same.

 

52mm is the biggest you can safely port the stocker. Yes, it works just the same. I have a ported stocker right now, and it worked awesome! But, my motor is telling me I now need a 58mm, as the dyno showed I flatlined at the top end.

 

so for my mods, I would be fine with porting the stocker? where can i take it to get that done?

 

Guys.. This dude has a LS1... Not a lT1. The numbers and info you are giving him is for LT1s.

 

thats what i thought. Cause i have seen 80mm TB's.

 

a ported stock throttle body ...on an LS1...is sufficient for most decent h/c setups with minimal sacrafice on power.

for your bolt on mods...just stick with a ported one.

only reason to upgrade these days is if you are going with a FAST 90/90 setup.

check out the vendor list, alot of the big online vendors offer ported TBs for reasonable cost.

 

only mods are in the sig...future are headers, puleys, and a S/C.

how much can i get out of a ported stocker (size)? HP gains?

also, how much can you get out of the TB bypass mod?

1 more thing...what is a FAST 90/90 setup?

 

I see.

what about these ones:

how much can i get out of a ported stocker (size)? HP gains?

also, how much can you get out of the TB bypass mod?

 

ported tb is minimal hp...nothing you'll feel hp wise, but i did feel a difference in part throttle response.

info on the bypass...even though it's for an LT1

 

in the middle of my TB project. Port & polish, bypass, and bump stop.

when i went to do the bump stop, pluged in my scanner, and it is readign 100% at full throttle...do i need a different scanner?

 

well, with the exception of the bump stop...i finighed the porting & polishing, as well at the coolant bypass.

gonna go for a drive in the morning cause its 2 am now.

time for some jameson and sleep.
