If your MAF, including the screen, is actually a restriction the remedy is a larger MAF, including the screen. Its hard to compare throttle body size to MAF size because the MAF has a screen that reduces its effective size, but the throttle body has its blade mechanism that also reduces its effective size.

Your car should be a little faster. No affense. I wasn't asking if it takes alot to run 11's I was asking him if that's what he was saying. I am only 3 tenths off now with simple/cheap bolt-ons. I get a fast 90 intake and fix my intake setup a little bit im sure I will be in 12.1 territory. Put some slicks on my car And get my 60ft down a tenth and im in the 11's. What is your 60 ft? And what d/a are you running in? What size stall? You should be running a little faster with heads and cam. And your trap is a little low for heads cam. I trapped 110 with a few bolt-ons....

If I ran in 1800 DA my car would run 11.5x @ 11x even with 3.42s as it sits.

No offense taken. I wish I could run in the DA your running in. Where I live I see DA around 3000. Im running a 224/230 cam which is not very big, and Patriot Stage II 5.3 Heads. Stall is 3600 w/ 3.42s gears. My 60ft is usually high 1.6x/low 1.7x. There is alot left in my 60ft & 1/4 mile with a 3.73 gear swap, but the car is primarily my daily driver. My car put down 398whp, so 11.76 @ 114.8 is about where I should be at give or take. This year Ive done more suspension and Im adding an underdrive pulley. I should pull off an 11.6x in my horrible DA conditions.

. I ran a 12.8 not to long ago in like 3800ft d/a. It was horrible hot. Like 100 degrees and so on and I ran a 12.8@106 with a 1.9 60ft. Track prep sucked cuz they were doing drag radial only times....

I didn't get to make it out to the track at the end of the season last year, so I'm hoping I can make up for that this year and get a new personal best time. Should be doable with the new mods.

The fast 90/90 isn't going to be a huge improvement now, but with a cam or heads (or both) it will gain more.
I went from a ls1 intake to a mild ported 90. I estimate based on track times to have gained right at 20hp with a cam designed to handicap poor intake flow.
On your car, hoping for more than 10-15hp is a stretch.

. Actually though upgrading my headers and cai would cost more. I will be getting the fast 90 and tb for $900 and selling my ls6 $300 and my stock tb $50. So I'm really only spending $550 on it. Headers with y-pipe and a cai would cost me $650 easy.
