30 rwhp? Am I dreaming?

The heads have consistently shown about a 30rw gain by themselves. They have also needed about an extra point of fuel as well. I would have to think about it but I am sure it has to do with the new flow ratios and it takes the MAF and VVE table to places GM probably never paid a lick of attention to in the tune since there was no need. I am actually going to have to extend my MAF curve again since I am pegged out right now. With all the extra flow available I am not sure how the stock manifolds or shorty headers would handle all of it.

Thank you sir!!

Are those stock run-flats on those wheels?

Yes sir

And did you beat that Corvette?

Hell no!! To my knowledge its built ZR1 H/C on dope with 15" rear conversation. He lifted and went a 10.0 against me

I was looking at my first trip to the track when the car was stock.

And since the difference in DA was mentioned I figured it would be good to also compare this slip to the Pray Ported IM/TB.

STOCK.......................AFTER
1.96...........60FT........2.02 <------ .06 slower
8.06...........1/8..........8.08 <------ .02 slower
89.9.........1/8 mph.....90.5 .6 mph gain
12.35..........1/4.........12.34 <----- still gained .01 with .06 slower 60ft
113.1........1/4 mph....114.9 <------1.7 mph gain

DA stock was 1956 and corrected to a 12.13@115.1
DA after was 2089 and corrected to a 12.04@117.8

Again I did not fight traction in stock form. After the port it was pretty azz happy.
