wondering what guys are running for a intake set up. Have LE2 heads & intake custom cam 239/241 range. seems like its starving for air

Whats your MAP readings at WOT?

Why you need to read a map?? It's a straight line...

LS1 lid is the best breathing by a good margin. Solid 1 tenth for me going from 4" aluminum pipe and a monster cone filter. IATs were similar with both.

IDK, they never mark the damn exit ramp well and it comes up so fast.

Solid .1 and 1 mph over the LS1 lid and that was with the old 350 cam/heads combo. But you can't have a stock hood. I use a Suncoast WS6 on my Formula

lol that is interesting; you would figure that they would paint the barriers a different color or something after the mark... Or maybe a set of lights at the very end of the track that light up when you cross the beam.

I am running, 3.5 inch with high flow MAF sensor. Does it take much fabrication to install on a LT1 T/A?

I am also Leary of my stock but ported 95 intake, any ideas?

You have any installed pics?

Ive made a ls1slp lid fit on a stock z28 hood with ls1 radiator support on mine.

I do not believe the LT1 MAP accurate at WOT on modded engines, given the location I think the Bernoulli principle causes higher than true MAP reading once moving much more than stock airflow.
Seen a 355 with dual cone filters 3.5"pipe no MAF, monoblade register vacuum, not a snowballs chance it was legit.

Interesting. I'm reading 87kPa MAP at 94kPa Baro. So, you're saying that actual MAP is higher? I'm running a stock LT1 48mm TB and untouched intake manifold, K&N CAI intake, homemade elbow, and Spectre Cone filter 4".

Relocate the MAP reference to a different vac port and see if the readings differ.

hrcslam

I'll give that a go.

I was thinking about adding the Chris1313 ram air to my SLP lid setup. Thought about adding some aftermarket bigger MAF ends but some people say they are more of a pain then they are a gain. Decisions decisions.

When you change MAF cross section it needs to be completely recalibrated in the PCM.

Are you referring changing diameter of pipe with a card style MAF or changing diameter to say a 100mm MAF tube (LSX style) from the stock ~3inch MAF (LTX style)?

CamOnlyJabroni

Yea I get what you are saying there. I am just wondering if I have a 383 that is over 500 crank would it be worth going to a bigger diameter MAF since that is the bottleneck in the setup. The car picked up quite a bit with the lid setup from the BBK intake. Those RPM speed MAF ends seem like they could be a easy swap and with a TUNE be cheaper then spending more money on a maf. For example a C5 ZO6 MAF or another 85mm MAF plus getting a tune. The higher power LSX cars pick up power with a bigger MAF so I don't see why a bigger cube opened up higher compression 383 would not benefit. Even though the LT-1 is sooo inferior.

Here is a link to those RPM SPEED MAF ends.

Ed Wright claimed single digit gains on his little over 500rwhp car by eliminating the MAF.
On the MAF calibration I am saying if you reuse the electronics with larger ends it changes the calibration.

CamOnlyJabroni

I am following you. From what I have been reading it really skews the low rpm flow more than anything un tuned. That may be the reason why I also read tuners don't like to tune with the bigger MAF ends. The calibration being thrown off makes them a basket case to tune. Check this out though. Some of you might already know but I just found this and ordered one since I still have the original smaller 75mm or so stock MAF. Part number AF10056 Delphi MAF. I talked to my tuner Solomon and he told me he is running this MAF and it has similar flow characteristics and was told I would not need a re tune. I got one off of Ebay for $75 shipped. 10mm or so bigger in diameter and should not need a tune. I call that two birds one stone. Love it! Had to share this
