Your numbers are giving me goose bumps. I’m so ready to see what mine will do if it will ever get finished.99 Cobra
1. 4V stock displacement

3. 9.7:1
4. Stock heads
5. Bullet Racing custom blower cams, PAC springs/retainers
6. Stock intake
7. Treadstone 1245-28 Air to Air intercooler
8. American Racing 1 3/4" long tubes, 3" x-pipe, 3" Magnapack catback
9. Using House of Boost renegade bracket setup (Stock diameter ATI damper, 8" crank pulley for blower), 4.385'' 8-rib Griptec blower pulley
10. Seeing 20-21psi boost
11. Custom fabbed 3.5" piping
12. 902/810 at 16.5* timing on E85 (Perfect dyno weather, started with a negative DA, and stayed around 0)
Ran out of injector (FIC1000 as I was planning to be on 93 oct when build started) and started going lean around 6500rpm, stopped pulls at 6800. Switching to FIC1300 and will try again.

This really makes me wish I had my 01 dynoed. I had my F1A at 19psi with similar timing. But I had a ported intake and a big bore stroker.99 Cobra

Hes a NT car. I doubt he’ll post numbers. He doesn’t need a Dyno to tune it since he has a holley. But it would be cool to see. Super cool guy I chatted with him a bit a few weeks agoDamn, 8k rpms on stock heads, that's awesome!! Can't wait to see these numbers.

Went back last week to try again after swapping to 1300cc injectors and a 4R70 swap, made 850/745 at 6500rpm on first full pull. Second pull was to 7000 and it flatlined on power and boost after 6500. Threw a new belt on and tried again and same thing. Not sure if I have maxed out the intercooler, or maybe getting all I will get out of the stock intake. I went back and watched videos of the pulls and once it hit 22psi around 6300 it just stayed there, so not sure there was much if any belt slip.
Here are both 7000rpm pulls
I'm not sure at this point. Going to work on some cosmetic things now and will circle back around to this later lol. I didn't think I would enjoy the auto as much as I do, it is a lot of fun!some pretty good numbers for switching to auto. So you thinking of porting the stocker? Going ported short runner? Going all out like a Sullivan or other aftermarket?
I bet that power feels good

That is good info, thank you. I suppose it could be belt slip. In the past when I've had slip, the boost would drop significantly. The blower should be able to make 25+ of boost with ease, so I don't think that is the issue. I have it pullied to where it doesn't reach max blower RPM until 7500rpm.if your boost flatlined you’re either out of blower or belt slip. If boost kept climbing and intake temps were skyrocketing likely out of intercooler. Through the auto that’s a lot of power you’re likely around 950-1k to the tires on a manual depending on if you have a locked converter or not.
The boost flat lining is weird though f1a blowers can be spun hard.
Another option is your intake can’t flow any more but I know of a lot of guys making insane power on a 01 style. Personally I’d switch to a Sullivan.
