SLP Performance Pac's, has anyone ever used one?

I looked at these on the SLP website a few minutes ago and for my 98' Z28 they make pac's with between 50-75hp gains, all through air intake and exhaust, so instead of putting flowmasters on, or swapping out my muffler, what about one of these for around $700?

Re: SLP Performance Pac's, has anyone ever used one?

way overpriced...and net even the best parts that are available.

their CAI is a waste of time, if you want ram air...go SSRA

the bellows are a waste of time..99.9% visual mod

stock maf is more than sufficient for 400+ hp

list of mods to start with:

SSRA - $200
Lid - $100
coated headers w/ ypipe - $600
either put a cutout behind your ypipe or get a cheap catback (TSP rumbler catback - $300)
LS6 intake manifold - used for $300
mail order tune (www.madz28.com) - $225

then worry about suspension

What is SSRA? And the cold air intake pac from SLP sounded like a pretty good deal if it adds the 25 HP to the wheels like they say. I mean it replaces alot of stuff, like the lid which you suggested doing. What makes it crap?

It's overpriced for one thing, and I don't think you will get 25 rwhp for this. You can get a whisper lid. The SLP CAI is not as good the FTRA. Take a look at both, the FTRA extends further down to get more air into engine, the CAI is too short. The bellows will give you 0 hp, it's an appearance mod.

Keep the paper filter. It's a $6 replacement every 7-10K miles plus you won't risk getting oil on your MAF. A clean filter will flow just as good as a K&N in our cars because it isn't a restrictive point. As mentioned earlier, the SSRA (Super Sucker Ram Air) aka the Austin Ram Air is a much better kit than the SLP or FTRA setup because it extends down far enough to be effective. And, the bellows is really a visual mod. I got it for looks. 25rwhp with the SLP pack? I don't think so. With the SSRA and a lid at speeds over 70mph, maybe. Don't believe everything you read. Marketing is everything in the aftermarket. Like my boss says..."In God we trust. Everyone else bring data."

In a recent test, SLP's lid came in second out of 4 or 5. Texas Speed & Perf. came in first. To find a SSRA, try Yahoo!/Google using "Austin Ram Air" in quotes.

Well, the SSRA looks like the best CAI to get but it's VERY expensive. Wouldnt it make your filter get dirty realy fast as well? But i would agree that it looks like it would give the best horsepower gain. And does anyone else think that Texas speed lids are the best?

Re: SLP Performance Pac's, has anyone ever used one?

If your car is a daily then dont get the SSRA. You run a higher risk of hydro lock. Thats why the SLP one is shorter to not pick up as much water. An LS6 intake is pretty much useless unless you are running a cam. Its a part that works in conjunction with others. You will not see a 15hp gain on a stock motor more like 5. If 400 dollars for 5hp sounds good to you then buy it. Also you wont need a tune unless you have some internal mods done like cam head etc. You will not need a tune for LT headers. My advice is this:


SLP Loudmouth flows the best for the price. ( or cutout)
LID is a Lid is a LID
LT headers
SFC's
Heads and cam depending on what size cam you want to go with.
Stall, or clutch
then suspension mods.

Our cars already make 345 at the fly so dont believe all those power pack crap. My car makes 380 to the fly but you dont see me with a 380hp sticker on it do you?

Re: SLP Performance Pac's, has anyone ever used one?

If you do go the heads and cam route then you will def. want the ls6 manifold I agree on a bone stock motor you wont notice much but if you get to the cam or h/c then you will want to upgrade the intake manifold

there are many routes you can take but basically like stated above it all starts teh same

lid,catback,headers,then id go with ls6 intake,cam,underdrive pulley,ported t/b, and of course suspension mods any where in there, if you do start taking it to the track alot itll be good info for you to know that the rear end in fbodys doesnt agree with sticky tires very well and that should be another point to address

Re: SLP Performance Pac's, has anyone ever used one?

i disagree on the power gained from the LS6 intake. it's been dyno proven time and again, both by members here and magazines. on bolt on cars (not h/c) it's showed a solid and consistent 8-10rwhp. and realize that is just peak, not to mention what it gains across the power band, which is what really counts.

used they sell for $300, plus $30 for the coolant tubes and plugs. pricey for 10hp...maybe...
but LTs gain you about 15hp and those run $600+ depending on brand

on cammed cars the intake has shown nearly 20hp according to some, but those are rare i think.


but..
for the most part i agree with the listed mods...good starting point


and as for the SSRA sucking up water
you have to be driving like an idiot through REALLY deep water to do that. in the past 2yrs i have only heard of ONE actual incident first hand (not..."well i hear you can hydrolock with..."). and that was in orlando area, some guy doing roostertails through deep puddles...

there is a bracket in the middle of the scoop that has room around it, meaning it is not a 100% sealed scoop. not enough to hurt purformance, but it will keep water out in most real world situations.

you realize the amount of suction it takes to pull water up that scoop? and even heavy rain, i've driven in hurricane storm rains....pulled into a garage and checked my lid....no water

Re: SLP Performance Pac's, has anyone ever used one?

What kind of HP gains do you think the SSRA gives, over other cold air systems?

Re: SLP Performance Pac's, has anyone ever used one?

at slower speeds...nothing...it acts just like any other cold air kit.

but at highway speeds i would say close to 10hp. it's been shown to yield .1sec increases compared to removing the lower scoop (making it just like the other brands).
