Finished Chris's 96 Cougar, 4.6 NPI, 4R70W trans, IRS. This is an unmodified plastic PI intake and PI cams, no other changes between these dyno pulls. Not exactly the peak difference I hoped to see, but still good. Power is +40 at the top end, fantastic for a $200 investment.
This car has an 02GT stock airbox/MAF/ziptube with paper filter and is tuned by me. Other than that the engine is 100% stock.
either the dyno spiked just a little, or i'd say that's the RPM the factory manifold is 'tuned' to. either way the two intakes are pretty close up to 3600....
well i wanna know how u make 197 at the tires on a stock motor im just curious cause if so that more than jls made he put down 199 with all his stuff beofre cams or anything so please give some info on this hotrod looks good those later
This just further proves that the old style intake is a horrid restriction.
That car picked yup almost identical gains on the top end as my car did with the ported heads,etc,etc,etc...
And that car is doing well to begin with Rob-it's a strong one,like Ms. Tana's car is.

I put down 196 w/ just a Hypertech, pulleys, and mufflers cut off about 1 1/2 years ago. Guy running the dyno kept letting off and trying different "techniques" becuae it kept hitting the speed limiter.
The key with that Cougar I imagine is Kdanners tuning abilities.
Not trying to get you down or anything, but I was wondering the same thing. I know peak numbers aren't the only factor, but how did you your torque go down by almost 30?
I mean from what it looks like to me the hp/torque curves were almost the same, except that your readings for the first run ended early.
Edit: that "spike" at around 3900rpms is where it got the 283ftlbs torque (kind of a confusing chart), but how you would you get a spike gong backwards in rpm like that? Did they let off or something?
Get some drag times and that what help. Dyno #'s don't mean everything
I don't think you're missing anything, I looked at your site, I don't see anything listed that is known to really make power, things like pullies, TB, K&N do very little and in some cases nothing for power. Jerry did teach me how to tune, and the new software is so easy it makes me look better than I really am. I wouldn't even think of the 8HP difference as significant whatsoever considering it is 2 different dynos. Plus it does look like there were some dyno issues considering the backwards squiggle in both of your pulls.
I meant to mention also, the best part about this car is his total investment is only about $4200. This includes installing a whole new center section and trans, brake rotors/pads all around, even the race tires.
The car will go to the track soon. I don't think full potential will be seen, the converter doesn't want to stall any more than 2900. I question whether it can run a 13, but I lean toward saying it won't without a looser converter.
Okay, so two years ago I got the P1443 and replaced all the evap hoses with fuel line and both electrical parts. I should say, all but one hose, the one closest to the fuel tank. I was pretty sure I could get that one off, but not sure at all I could get a new hose on there because it looked...
Hey guys, it has been quite a while but it's good to be back!
I am in need of some guidance regarding a recent engine swap in my 97 bird.
The back story:
It has been quite a while since I have posted, mostly due to the fact that my motor exploded roughly 6 years ago. Since then the car has...
Hey guys,
I'm giving changing my motor mounts another try, and instead of going through the torture that removing the mount+bracket out of a 2x2 inch space was, I was wondering about the service manual's procedure for changing them.
The one thing I wasn't sure about was that it instructs you...
