Congrats RB! First S550 N/A to hit 9`s! I see your still running the stock heads with no porting is that in the future?

Thanks Stang Racer! This is RB`s dad he works 60 to 70 hours a week so not much time to post. It`s been a long road RB doing his own work from a carport since he is working 500 miles from home but it will be next year before possible head work they have never been off the car yet! Still running stock 2015 heads with over 22K miles and hundreds of 1/4 mile passes the last 5 years.

Well done!

Are you foot braking the car?
Thanks Troy, yes he is foot braking at 1,500 RPMs anything above that he blows the tires away. He is running a small tire now but soon changing to a big tire for a harder launch hopefully a little more ET gain.

Any pics or details of the OTR intake?
Here is a partial pic RB is still testing his home made setup, it is more for racing but he will share more by mod nationals..

Nice, been dying to see one of these intakes paired with the high revving manifolds.

That small tire is working well for him!
Thanks Troy, He did get some 1.38 60 ft with a soft launch bur the problem with that tire now is going through in 3rd is 8,650 RPMS or shifting into 4th before the finish. He is getting ready to test a taller but heaver tire for higher RPM launch and hopefully finish in 3rd lower than 8,650 RPM.

I wish I could add more but it's been a while since I've played with cars and am using RB and the Steeda cars as guides to get my 19 GT up to speed. I personally plan to use the 275/60/15 Radial Pro's for track duty which is a bit taller than what RB has now.
