how big of a gain did u notice when you ported your tb?

 

Stock MAF for me here at over 500 rwhp. FWIW...

 

 

I wish I was there, it's driving me crazy driving a stock car right now

 

Then later down the road a 90mm tb and street warrior intake !!!

 

I did not get it on the dyno but it was noticable. I put it on and i was like damn i wasted more money. Because driving normal around town i didn't feel anything. But late that night after a car show i ran a lightning and i almost hit the rev limiter because it pulled harder up top. I could really feel the added pull in the upper rpm's. And of course i won the race
