i have a k&n intake will this TB fit on that ?

 

It should, but I dont understand why you need the adapter? It looks to me as if it would mount right up

 

It for the tb blade. It extends outside of the tb and will hit the sc with out the spacer.

 

ok and what spacer is that, that comes with there intake ?

 

with the K&N it might but the K&N Typhoon intake are 2.5"... try to find a couple from 3.5" to 2.5" is impossible... lol

 

ya i got the k&n typhoon

You can order the intake and the spacer with a discount.

 

nop GB is done .. :P

 

how big is the 3.5/3.7/4.2l throttle body??? does the 4.8/5.3l throttle body work aswell???

 

well if you saw the list.. the 3.5L colorado is 3.5" and the 4.2L TB's are 3.5" also and the impala ss 5.3L is 3.5" also..

all tb's in the list i gave are 3.5" which fits on our supercharged with the spacer

 

Would this mod run the car to lean if it had a 2.9" pulley instead of the stock stage 2 pulley. Assuming it was runing on the stage 2 tune with only the Scalar area changed to 4500 as noted?

It said that the test car with the stage 2 pulley commanded a 10 something A/F ratio after 6000rpm?

Do you have a copy of the A/F log to go along with the dyno sheets posted for these runs?

I am sure alot of members are like me and run the stage 2 with a 2.9" pulley and want some additional clarification before installing this

 

The GM tune is very rich up top so the increase air flow will only help while keeping everything still same and in the low 11's.

Sorry we don't have the AF charts but from what I remember it was in the 10's from 5000rpm on.

You have an email regarding your mods

 

Amazing gains

 

hmmm i think this might be my next mod, with my injen intake fit the LS4 TB?

 

asked about this mod over a year ago and got flamed hard about it. I think it went to like 20 pages about how it wouldnt do anything at all. This is exactly what I thought would happen based on the dynos...awesome job, im getting one.
