Boss Manifold First Impressions
I installed my Boss 302 Intake Manifold last night, and am thoroughly impressed with the fit and finish as well as the performance!
The install took roughly 1.5 hours, but I could knock it out in an hour if I did another one.
I followed the install write up from Latemodel Restoration found here:
http://www.mylrs.com/blogs/lrs/archi...tallation.aspx
The instructions were spot on. The only exception I found is that you don't need a 3/8" fuel and a/c disconnect tool to separate the fuel line from the rails.
You'll also need to decide how you want to mount the purge valve as it needs to be relocated for the Boss Manifold. You can use the option which is outlined in the write-up linked above for around $10, or you can opt to purchase the $200+ kit from Ford which will give you the OEM hose and bracket, but it will also require that you extend the harness for the purge valve. Latemodel Restoration also carries a kit to do the DIY relocation for $10. I of course ordered the DIY kit from LRS with the Manifold and saved myself a trip to the auto parts store.
The manifold itself sits quite a bit taller than it appears in pictures. It's just about as tall as the Saleen blower on the 3V. Looks **** good too!
I'm running the JLT Cold Air and a JLT Oil Separator. Both fit beautifully in this application. I had heard of others claiming there was a dip in the intake path between the cold air intake and the throttle body, but I have no such thing after spending a little bit of time adjusting everything to fit just right.
I had expected to lose a little bit of power below the curve, but gain substantially above 6500 rpms. At least this is what's come to be expected with mild N/A set ups. I thought my 3.73's would make up for the low end loss, but unfortunately I can still feel a slight loss on the low end.
The power up top is great and more than makes up for any low-end losses. It just keeps pulling way past redline! "How far do you dare to take it" is what this intake has me thinking!
This leads me to where I may be headed next...
4.10's and a 1-piece drive shaft!
I really feel like the two of these mods will make up for the low end loss, and will also aid in keeping those rpms up.
The one downside here is my clutch is starting to slip. I'm thinking of going with Ram or Mcleod. What are you guys running? I will be getting a Procharger in the not-to-distant future, so I'll need it to hold up to 700 rwhp. I don't plan to take it that far just yet, but I'd rather have it if need be.
Cliff Notes: Badass intake manifold! Looks mean and acts mean! Simple install and immediate results! Still has me needing more...

Looks good.
Did you dyno it at all? Whos tune did you use?
I just installed mine last week and do like the extra top end power. Mike @ Bama hooked me up with a killer tune and she screams to 7500 no problem.
Took the car to VIR this past weekend and wooped up on some serious cars. Everyone was impressed.

Awesome post, S197!!
I like where you're going with the lower gears and reduced rotating mass from the driveshaft (we could all use that, actually)...
Keep us posted.
Does it sound any different?

Wow looks great man! That's quote the laundry list of mods you have now.
Made by JLT, check it out here. I wish I had known about it when I bought my car. Who knows how much oil I could have prevented from going into the manifold. Well worth the money!

I love the Powerhouse driveshaft on my '05. Great mod for tightening up the slop in the drive train and freeing up some rotational mass!
It actually doesn't really sound much different.

Dyno should be a few weeks out guys. But I'll at least go to the same dyno as last time.
I put out 425 rwhp and 427 rwtq before the Boss Manifold.
It had it retuned by Jon Lund for the new intake.
