Actually, my cost numbers are now irrelevent. #1 it was purchased and installed 15 months ago. #2 SLP has modified the heads w/larger valves and I'm sure there's been a slight price change due to that and the passing of time. #3 SLP no longer does install or dyno work at their facility. Thats truly unfortunate as they were just great at it.

You'd be best off if interested in purchasing their parts to call them or a sponsor and have your trusted shop do the install and tune.

Just a quick question. Did they pull the engine to dyno it at the flywheel?
If not then you shouldn't state those numbers as fact because they are just an estimation. The real flywheel numbers could be much higher or lower.

 

good point, yet another reason i steer clear of slp. they have done good tuning on cars at there shop though!

 

Al,

Just a quick answer.

I shouldn't state them? Why? SLP did the parts install and dyno tune. They obtained the results. I received the graphs. Upon arrival to pick-up the car, I received a complete explanation of the car's performance across the RPM spectrum resulting from the work and tune. All numbers and graphs were given to me. Your comment sounds a little "nitpickey." If you're not convinced w/the FW numbers, ignore them and just rely on the RW numbers. What's the big deal in regard to a setup that is now 15 months old and not even offered?

FYI, SLP dropped all engines during H&C install. My engne was dropped to install the H & C & headers.

BTW, the numbers are real and accurate. The RWHP & RWTrq numbers have been verified by additional Dyno readings since pick-up. Sorry, but I can't verify the FW numbers, as I haven't again needed to pull the engine. It's been reliable for the last 15,000 miles.

I don't quite understand why it would be sensible to steer clear of a tuner when they do good tuning? Hey guys, lets not hijack this thread into a "kick SLP" post.

joSShua, initiated the thread and asked for input. It started as a request for info regarding the SLP kit. I have the package, I'm in a position to give actual numbers, and I'm happy w/it. If you're not interested, you're not interested. Why the attitude regarding my results? I should think any Fbody owner would take a certain degree of pride in knowing that a Firebird is capable of embarrasing an M3 or Cobra at Summit Point.

The numbers produced by the present day SLP kit would undoubtedly be higher based upon an improved head design incorporated into their package. My results are w/the original heads offered by them. As I noted in my first post, there are other performance parts houses and tuners who can and do achieve better results. My comments were intended to directly address the posted inquiry and give him the info he requested.

Your mileage may vary.

Steve

 

because they are overpriced but a good friend that lives out on the east coast goes to them for all his tuning..... he keeps pulling more and more amazing times!

 

Unless you pull the engine then you don't know what the flywheel numbers are. Nittpicky yep. I hate to see people make statements of facts that they have no way of knowing.
If you had said should be approximately xxxhp and yyyTQ at the flywheel then fine. Everyone would know that the numbers are not exact.
I have no doubt of the rear wheel #s as they can be measured.

 

As noted above (I'm sure you read it) the engine was removed. The parts installed. The ratings measured.

I hate to see people waste others time on such uninformative issues expecially when it amounts to a hijacking of the originator's thread. It was out, the power was measured. You're wasting everyone's time w/this endless, pendantic, kicking the can around the block.

Thanks guys, I am sure that there are other companys out there that make AWSOME heads and cam packages but I was interested in SLP's 485 HP package. I really don't care about the price because I trust SLP and know that they back up their work...if they didn't then GM would not bother w/ them.

As for asking if a head and cam package (w/ obvious boltons...headers, LS6 intake, etc) could make 500hp, I did not specificy what I wanted. FWHP or RWHP? It does not matter now anyway because it could not be done at the rear wheels w/o NOS, a blower or increasing CI. 500 FWHP would be fine but I still want my car to be street friendly. \

Thanks for sticking up for my original post steve-d! BTW, did you say that SLP does not do work on cars anymore?

 

Steve,
Did you even read the posted quote above before hijacking this thread into a pissing match?
All you had to do is say "yes". End of discussion. If the motor was pulled and dynoed then the rest was moot.
But apparently you felt the need to justify the excess money that you spent.

 

:werd: the crux of everly slp supporters arguement.
