With the lid option yes. CME AND dual-dual's have the same hp bump (+10hp).

Peace,
Craig.

 

Not any significant advantage....but of course most who have it like to think so...

 

Most of the advantage is in the induction and can't easily be measured on a dyno.

 

^^^ Sorry it CAN be measured. In fact IT has been. Conclusion? ALL LS1 equiped cars HAVE 345 to 350HP at the crank....even Vettes with same engine.....

 

Wrong, are you saying that a lid and cat-back will not yield any more hp? They do.
The dual-dual is a very well flowing cat-back, why do you think people are always buying/selling them? They may not flow the best but they do flow well.
And the lid, waaaay better then the stock baffle set-up.

So yes, I bet you see more hp's on an engine dyno or chasis dyno. To know the exact amount you would need to have the parts swapped out on the same car, same day, same shop.

Peace,
Craig.

 

I still stand by whatt I say....not a SIGNIFICANT difference.

From the JRP's FAQ on THIS site:

Heres the link.....

https://ls1tech.com/forums/new-ls1-owners-newbie-tech/213148-jrp-s-faq-commonly-asked-questions.html

Rest my case.....

 

I understand now what you mean. BUT, by performance package they mean JUST the SS, Firehawk, or WS6 option. The SS and Firehawks from SLP have the option of a lid and waaay better cat-back over the base performance package option.
Hell, Tony (Nine Ball) had a 35th Anniv. SS, BONE stock it did 321rwhp (M6) while most 01-02 M6 cars did 310rwhp.

So, when they say performance package it means the standard option for the ram air cars, not the other options SLP offered. A lid and a cat-back will help period, otherwise why do we buy them?

Peace,
Craig.

 

Is there any difference between a SLP SS and a SLP WS6

 

Yeah SLP did not make the WS6, SLP made the SS and Firehawk. ASC made the WS6.

Crager is right though, lid and catback will show more ponies than just a stock LS1.

Our A4 SS put down 323 off the lot (with the 345 option).

But that was a long time ago...

 

Who in the world is ASC never heard of them the reason i asked that guestion bout the difference between the Slp SS and WS6 was because i saved a pic off of ebay of a 01 Ws6 that had a Slp badge on it in the same place the SS has it i am guessing that someone just put in on there for looks

 

So Azreal, what are you going to do 25 years from now when 'unmolested' NBM 02 SS's are rolling across the Barrett-Jackson stage for $500K?

 

Wonder where they find people that would pay that kind of money for a car, and be glad I had the fun when I was young enough to still enjoy it!

Life is meant to be lived, and cars are meant to be driven. Can't we all agree that "SS" stands for "Stock Sucks!".

 

Yep, or they bought a Loudmouth exhaust or other SLP product. ASC did the WS6 conversions though, not SLP (except the LT1 WS6)...

 

Ask any of the old timers if they ever thought their '69 camaro, vette, hemi or whatever would sell for a million bucks. J/K about your car of course, but, but, but, one day we will all look back and say, "I coulda had one of them there cars for 30 grand"! Don't know what cars will be involved or when the cycle will come around again but it probably will.
And there will be a few surprises!

 

thanx man sweet ride love the colors

 

ASC started out as American Sunroof Company decades ago and is now American Specialty Cars. They design&build show and niche production cars for the OEMs. ASC did the '98-'02 WS6 and engineered the 4th gen vert, did the GNX, and the SSR among many others.

The SLP badge was never put on a production car, they are all owner-added.

 

Also, with the 345 option, the SS betters the WS6 by 20HP (according to the official numbers).
