We have run into a few minor glitches with the car and a ton of unrelated bs that has delayed our efforts, but the intake swap should be finished up in the next week or so . All the hard stuff is done,,,building new throttle body linkage, building brackets for the TV cable and throttle cable, installing a longer cable, and wiring in the Ford TPS. We'll post pics and dyno results as soon as possible!

On that spring topic; here's a tip for those that have never installed aftermarket proformance valve springs, always, always check spring hieghts. Just because they'te Crane (especially so with them) or another maker's high pro springs, that does not mean they are the correct hieght. If they are too high they will wear out your cam in no time at all. Check em and get the boses machined if need be.

It looks like the magic barrier is 150 RWHP, and anything over 200 ft lbs of torque. Can't wait to get my 3.4, with the modified stock intake, dynoed (if I ever get my transmission back). Just wish I had a couple chips to try out as that seems to make quite a difference. Wondering if the 17# injectors will be big enough but with the adjustable pressure regulator I think they will be.

Curious if this ever got done and dyno'd... lost thread or a newer thread somewhere?

Are you saying check them before or after install?

You check them right out of the box. Look in any OEM shop manual or Hayas etc. It's easy to do and important! A lot DIY guys never check, mostly because they don't know they should and lots of times you can get lucky, but not every time.
Yep... its done and tested. Though we want to get some results with a properly tuned chip under our belt before posting any dyno results. The reason for that is the crappy A/f ratio. Check this out...
The best run with the 11- 11.5 ratio was the one where we set the fuel press back to 38psi. When rating these 19lbs injectors, ford uses this PSI. Any lower the fuel would not have atomized properly.
I will say with the A/f ratio so far out of wack the car is following its earlier trend of alot of low end TQ with a severe drop and the RPM increases. The HP is also being held back by the A/F. I will say this... in this thread my TQ number were surprising people... well the TQ numbers I'm getting now... WEll lets say I about fell over when we saw the amazing gain I got. This intake is definately worth it! And its taking full advantage of the mods most thought were just mismatched!
In you alls experience... what does having the A/f this horribly off do to your overall Power bands? Could the A/F be why in the past my HP seems to never really get much better??? Any opinions here would be great. Just wondering what we should expect 2 c with a good tune and numbers in the 13-13.5 range....

Great. So what you got? Could you please share the dyno chart? Tks
PS: Nice engine

Yes I have the dyno chart as well, but I'm holding off on posting them until we can post results with the Trueleo chips. There was a gain in peak hp and a substantial torque gain with the stock chip, but seeing as how our tune is so far off we would be doing Trueleo a disservice to post just the current results. It all will be posted at the same time. I will say this...even considering the horrible a/f ratio, the intake is already BY FAR the single best modification we've done yet, including the 3.4 swap and the exhaust upgrades. With a decent tune, there are going to be a lot of surprised people, esp the naysayers on thirdgen.org! We're planning on bringing the car to this weekend's GA club meeting if anyone wants a closer look, or has any questions.
