SLP Performance package
Vette magazine on line has a good tech article on their performance package. This is a good bang for the buck. Dyno proven 50 crank HP for about a grand and torque to boot. Best thing about it is the roller rockers are basically hidden and the other parts are driveway bolt ons. The driveability of the car will remain good. Maybe a slightly lumpier idle but thats all.
There's lots of talk about getting HP and everyones got their ( I can do better than this) but IMO this is a good package, one I will consider next year.
Read the article. Dyno sheets don't lie. I'm impressed. Lots of other ways to do it but they usually have side effects. Heat, detonation, finicky. I think this one is pretty good.

Magazines don't make money by giving honest reviews on their vendor's products.
SLP claims "up to" 20 hp on their cat back, "up to" 7 hp on their air foil, and "up to" 20 hp with the slp cold air intake I bought..
Now the early c4 cold air kit is a legit cold air kit.. but no way in hell it gives 20 hp.

Well, that was my car they used. Their dyno is different than the dyno at ECS where I had my car dynoed a few years ago. A few years ago I made 285 to the wheels with 309 lb/lbs.
That was with a Corsa catback.
The numbers in the article are way lower than what I'd previously done. With the SLP exhaust the car made the same power as with the Corsa.
The full package was this:
1.6 roller rockers
shorty headers
AFPR
air foil(hey it was for free)
the triple cone intake
catback exhaust
I don't know if they tweaked anything in the PCM and I've not had a chance to visit the track to see if in fact there is any difference in power, though I'm sure there is some small gain.
I'm not one for seat of the pants reviews, but the car pulls just as hard if not harder than it used to.
The timeslip will tell the story, if I can run better than my best of 12.97(when the car was stock) we'll know if this is all worth it.
It was worth it for me since I didn't spend a dime.

Okay so now I'm confused Mojo. Are you saying they installed shorty headers as part of the package and didn't report that? Or was that part of a previous package you had on the car?
I think the 1.6 rockers are a given improvement. It seems by what the guys are saying is that corsa exhaust is the way to go and just about any reputable cold air intake system, and forget the airfoil.
So with the above three inprovements
- cold air intake
- corsa catback
- 1.6 rollers
............ what kind of HP improvements and torque would you guys think you got. 15- 20 HP?

I don't remember them saying the car had headers on it. That makes sense now when they claim the HP numbers when the changed the exhaust and intake filter. More air in + more air out= HP gains.

Wait a second here. Some of you guys shouldn't be beeking off here without a clue.
No one said these numbers were achieved. SLP got 8.3 crank HP and 9.8 Torque out of the ram. I don't think thats unreasonable. 7.7 HP out of the catback is right on IMO.
Another thing about SLP. They have been around a long time building systems and factory endorsed systems for GM camaros birds and corvettes. Their not about to lie about numbers and ruin a lot of credilbility they've built up over many year. Vette magazine is quoting SLP's numbers. Not inventing their own. In case no one actually ready the article that provides the dyno sheet the numbers are:
cold air- 8.3hp and 9.8T
exhaust- 7.7hp and 7.6T
1.6 rockers- 11.4 and 10.2T
RWH before 277hp and 265T
after 304.5hp and 292T increases of 27.4 and 27.6
FHP went to 350 and 357Torque.
.....cmon I've been in and around racecars and racing for near 40 years. I don't take this **** lightly. I asked for honest opinions not rapping off the top of your heads. Never mind, I'll make up my own mind. Sheesh.

Ex. and correct me if I'm wrong:
Cold air intake might produce 3-5 hp w/factory headers, but with aftermarket headers it will do 5- 10hp? I'm basing this on the theory "more air in and more air out" based on flow.
