Big power stock intake manifold users; How fast have you gone?
#1
Big power stock intake manifold users; Post your times.
Looking to see how fast people have gone on a ported stock intake manifold, regardless of who ported it. Please post a short description of your setup as well... mainly looking for cars that are trapping 140+mph.
Current list in descending order by MPH: (I will add your results if you have gone over 140MPH.)
David@Buschur Racing:......9.0@159 mph on Wilson V2
David@Buschur Racing:......9.1@159 mph on BR ported
Tom Powell:........................9.2@157 mph on Wilson V2
Mike@AWDMotorsports:.....8.9@156 mph on BR Ported
Chris Cessna/STM:.............9.7@155 mph on STM ported/2.0LR/6262
Dan@Buschur Racing:........9.6@150 mph on BR ported
Dragking2189's friend.......9.7@146 mph on Br ported
Hamx0r............................10.0@143 mph on BR ported
Alan Szabo Jr:....................9.8@141 mph on BR ported/HTA86
For those interested, I am switching from the AMS F1i to Curt Brown's extreme ported 70mm intake manifold w/ full blown 70mm TB. Will post overlayed dyno graph of both and will have track times come April 20th with the curt brown manifold. Tscompusa or I will make a new thread in the dyno results section and post the link.

I trapped a best of 132mph on a Fp Red, stock head with just cams and valve train/stock bottom end with just bolt ons pretty much full weight back almost 4 years ago. The stock intake manifold was not even ported lol. Then I went back to the track with a few changes and put a rod through the block lol

Actually.....
Mike@AWDMotorsports has gone 8.98 at 156 mph-BR Ported
David@Buschur Racing, has gone 9.04 at 159 mph-V2
Tom Powell-9.2@157.9-V2
David@Buschur Racing, 9.1@159.x on BR ported
Dan@Buschur Racing, 9.6@150.x on BR ported on radials

I looked at the link, I didn't realize at first why you were asking about the times. I like Curt a lot, we've done a lot of good things together. I'm gonna comment though on it all.
First, I've done a lot of intake testing, more than anyone else I am absolutely sure of that.
The thought of cutting the inlet off to the stock intake and changing to another flange is interesting because it's easy work. Well, I went back and grabbed a flange we had left over from our fab'd intake and grabbed one of our stock ported intakes and took a look. The inlet to the stock ported intake is basically as large as you are going to get it because of the physical restraints of the plenum. You could squeeze a little more size into that area by changing the flange but in my opinion, it's not going to do anything.
I also spent a lot of time testing the differences in intercooler pipe diameters and throttle body changes. Nothing makes more low end power than the stock TB, nothing makes more low end power than 2.5" i/c pipes. The gains down low from stock compared to the Skunk make sense as the Skunk low end lacks compared to the stock intake/TB.
I don't like any of the aftermarket throttle bodies, I think ALL of their idle control sucks.
Also, from my testing, on a 2 liter and on a 2.1 liter no intake out performed our Fab'd intake for top end power. Unfortunately we can't get our intakes to not eventually crack, so we stopped building them. Power department though, I didn't find any that made more power or a better curve. At the Shootout this last year Chris Young had our intake on the car, it cracked. I had bought a Skunk from Emery to test with the throttle body. I gave it to Chris and he swapped it in the parking lot and we put the car back on the dyno immediately after. (proper dyno testing, same day, same car etc.) The Skunk, even with 1 psi more boost didn't beat our intake with a crack in it BUT it was the closest I've seen from any intake and in reality I'd call the test "even".
Just my input on intakes, for the 100th time

David, thanks for taking the time for posting your findings. I have read through a lot of your testing on highboost as well, very good stuff. I am currently on a standard 2.0 with 10.5:1 compression. All my IC piping is 2.5" with the BR race core.
I do agree the idle control on the aftermarket ones are not nearly as good. You can get them to idle decent with more work, but there's nothing like the stock TB for sure. I can only speak for the full blown 70mm however.
My biggest thing is being able to switch to a stock intake manifold, without loosing an excessive amount of power in the top end of the power band. I can deal with loosing 10-20HP. The low/mid gains are definitely a plus however since my car sees more street driving then the drag strip.

the full blown idles like stock, but takes more work of course. its true nothing is as user friendly as the stock throttle body. i don't like the fact the full blown can crack either. but i have had no issues with it personally. this is a video of my car idling with it: https://www.youtube.com/watch?featur...C3GvWos#t=126s pretty much as good as it gets minus it needing a quick afr tweak.
the map rev 3 and Curts 70mm is cut open though and ported out. you don't see any benefit in that David? Cutting it open to port it more?

I have Curts manifold in my possession now. Either Tom or I will post an overlay graph between the F1i and his manifold to show the power/curve/spool changes. Should have that this weekend.
I plan to also hit the track April 20th.
