it seems that the ported throttle body picked up more down low, and carries the gains longer. The ported tbody picked up 20 down low. Makes me think the throttle body you posted is to big for the motor.

 

It might be. But 20whp on your dyno does not equal 20whp on the dyno shown. Gains were made with both.

 

its apples to apples 20 whp before and after on any dyno is 20whp

 

Ah ahhh..

Lets say I take my car to dyno A and put down 260whp. Then I go to dyno B and put down 220whp. Same setup, different results. That means that one or both dynos are giving incorrect numbers.

If I got back to dyno A with a new mod (lets say ported tb) and gain 10whp. Should I expect to gain 10whp on dyno B?

 

what your saying would absolutely be valid in a different conversation. All tests on the throttle body we did were done on the same dyno, same day...within hours. It could very well read high, or low..but that does not matter because we have a constant. So, if you are saying the dyno you posted was done on different dyno's on different days..or the guys at Rebal got bored and started driving around to every dyno in there area to come up with there results on a particular day..which is certainly doubtful, we are both comparing a gain seen, at a certain rpm range and power under the curve.

 

i think you need to read this, and possibly get the sense of humor mod as well

Im still torn about this, i can get either a ported throttle body for 100, or an LS4 for 100. I dont know which would be better in the long run. I was thinking about going TVS

bump

 

id go ported stock

 

just call ethan and he will port one for u for way less than 100 and have it the same day

 

What happened to the pics of his sister...STILL WAITING!!!

 

yeah im kinda leaning towards just porting the stock throttle body

 

i don;t think is tool hard to port the tb yourself? what will it take to do it yourself? i got a machine the can do the kind of job i just don't know what applications to use? any ideas? bump

 

you just gotta watch what your doin, dont take anything out around the blade,

 

I was debating doing this till I found a thread with such a great write up thanks!

 

How much does this cost now and after pnp did you have to retune

 

its $100 including return shipping. and i was only on a stage 2 tune no other tunning.
