I know, I was really hoping to get it on that last one, then the tires broke loose and it was over. My centri is probably even further out. Gotta get the fuel system established first! And ideally, the driveline, but I think I will be impatient and do that afterward. I want that boost! Lol.

So for my weight reduction, I got the car down to 3,565 lbs without driver, with:

Skinnies with bias ply M&H in front
Ran with 1/4 tank of gas

Removed:

Passenger seat
Back seats
Front crash bar
Front sway bar
Factory washer fluid bottle and lines
Air filter (remove only at track)
Exhaust system (running open headers)
Engine cover (because LOD intake)
Trunk floor/liner/air pump/styrofoam

And the ET Street R bias plys that I DIDN'T :mad2::brokenheart: get to use were 8 lbs lighter a piece (of rotational mass mind you). I used my old ET Street S/S and with heavy 17x10.5 Racestars, those are actually only 1 lb lighter than stock 20"s with a street radial.

So you did the trunk floor mod and how much did it save?

Wow not as much done to lighten it up as I figured you'd have. I didn't lose that much with my rear Welds as I hoped, but I also have a slightly larger tire on the back. The front lost about 30 lbs a side with the skinnies though.
I also thought about removing my air filter like I use to back in the day. Had a couple worries though track is always horribly dirty/dusty and its tuned with my Vararam so never had the balls to try it. You probably pull more air with your intake than I would and benefit from it though.
Thanks for sharing on what you did for weight reduction. Now get that beast into the 10's next time!:thumbsup:

Congrats Chris!

I didnt weigh the trunk stuff but I am guessing no more than 10-15 lbs. It just didn't seem right to keep it in there especially with all the stuff out.

Thanks Lazer!

I am planning on a 15" Weld with the 275 MT Pro. It seems to be a fast wheel/tire. I think I am all done for the season, so we will see when we'll see!:happy0180:

Still struggling to leave on any power. Car was 3340 and I was just making clean shifts not beating on the trans. Going to make a few changes for the spring. I know it’ll go bottom 10s I just have to leave hard enough.

It definitely picks up plenty of mph

This thread died. Anyone got any updates on their intakes since November?

I remain unconvinced that this manifold really shines with these sub 7,800rpm combos. I think the give up on the mid range hurts more than the gains on the top. With combinations to take advantage of the extreme high rpm performance of this manifold then maybe it's advantage would shine, but I think 9/10 cars that have this manifold would probably go faster with a Holley High Ram or a CID. It get a lot of credit for fitting under the hood - but I think that comes at a price...

Over on LS1tech, Lazer is going back to long runner and "smaller cam." He has done the work and is making the change...

Yea, Phil and I chat a good bit on Facebook. I think, in a perfect world with lots of time (and hood clearance) he should have tossed a Holley high ram on his SS4 NFC setup and I suspect he may have found another tenth and a half. I'm definitely interested to see what his new combo does.

That nice hump in the mid range on the dyno chart of the Hi Ram did look nice, didn't it? The LOD still beat it on peak numbers up top, but the differences in the curve shapes were interesting, Andrew. Its a shame we don't have more track data.

I tend to take note of price point, for what each of these manifolds are and do. What are your options with the Hi Ram and the CID; new hood/no hood/start cutting? Decisions, decisions. I agree, the manifold is meant for either an 8,000+ solid roller NA application, or boost. I still believe that my LOD manifold and overall build with an F1-X is going to be a very efficient combo. Looking forward to posting those results when they come to fruition eventually!

This comparison says a lot. They are within 3 peak hp, but the high ram makes more everywhere under 7400, and really stands up nicely coming up through 6000, where the LOD is a more linear build. The 5600-7600 average is 10hp and 10ft/lbs in the high ram's favor. Under 5000 the LOD really signs off, where as the high ram maintains a more reasonable fade.

But, you call out an excellent point, the high ram requires extensive PITA modifications to use on a 5th gen. The CID is even more of a PITA (and makes even more power!). And, you're dead on, I think under boost the LOD is going to shine - and it makes perfect sense for your combination. If you were staying all motor, you might have more to consider, but with boost, keeping it all under the hood, it makes good sense for you!

Here are the results from GPI all compiled. Got tired of paging up and down when I was looking at intakes so put them all together.
