Mods hp?

[00ls1bird]

Ok...sorry for the boring how much hp thread but I have searched the forum and can't come up with a good estimate. I am hoping for 10-15rwhp. Sound reasonable?:thinkin:


Here is what I will be doing this weekend:

FRA mod
SLP Lid and K&N filter
ported MAF housing

PS: Havent picked up the filter(50bucks), will this yield enough hp to justify itself?

sounds reasonable.those are some of the first mods i did and i noticed a good seat of the pants feeling.yes the k&n filter is worth it. i descreend and cut the maf halfs and polished it out, shortly after that the car started pinging on the top end. i had a spare maf housing that was just descreened so i put it in the car and it stopped the pinging. i would personally recommend not doing anything to maf housing aside from maybe just polishing it out but thats just mho. good luck!

7-10rwhp sounds about right...especially over the stock system. I noticed a stronger pull up top when I did the fra and a lid. Do a good tune up while you're at it if you haven't already. Wouldn't do anything to the maf if I was you....descreening shouldn't hurt unless a big piece of debris gets in there

I won't buy a K&N, You won't get a gain for the money spent. I could search and give you all the math with surface area formula's. + oil on the mass air. My .02

Well I got the lid on today. Dont really feel much different. Looks nice. I decided against the MAF porting. Holding of on the FRA mod. Still thinking about the K&Nfilter.:thinkin:

You likely won't notice the difference until you do the FRA mod. That will enable your LID to go to work for you.:drivin:
Oh yeah the Holley "Hole Shot" filter is just as good ( if not better) than the K&N and is cheaper.

Wish I did a baseline on mine before lid / catback / filter.

When I did a lid and filter, I noticed better throttle response down low more than top end or actual accelleration.

I had my K&N off the first time I put it on the dyno. I did try a dyno pull with no filter at the time and gained less than 5hp. The last dyno we did several pulls two w/o a filter, the highest number in in the sig and was with a Fram paper filter installed. I still have the K&N somewhere in the shed but have no future plans to use it.
