I recently read in a preview guide of 2006 vehicles that the only change for the SSR for 2006 was that the LS2 engine HP was to be increased to 395 HP. How is this being done and will it be possible to reprogram the computer in a 2005 to attain the 395 HP? Cleavermodels :flag

It's the same. Just measured differently.

Nothing is different. Look closley. All they did was rate the horse power at a different RPM.

2005 SSR is 390 HP at 5400 RPM
2005 SSR is 405 Torque at 4400 RPM

2006 SSR is 400 HP at 6000 RPM
2006 SSR is 400 Torque at 4000 RPM

2005 Corvette is 400 HP at 6000 RPM
2005 Corvette is 400 Torque at 4000 RPM

It's the exact same engine with the exact same horse power. So, if you want your 390 HP 2005 SSR to match the 400 HP 2006 SSR, all you have to do is step on the gas and take it from 5400 RPM to 6000 RPM.

Whenever you see a horsepower rating, the most important fact and equalizer is at what RPM the HP is being measured at. Chevy Marketing wanted everybody to think that the 2005 Corvette was "tuned" to 10 HP more than the 2005 SSR. But, not true. The 400 HP on the 'vette was measured at 6000 RPM and the 390 HP on the SSR was measured at 5400 RPM.

Oldest marketing trick in the book. They are the exact same engine and are tuned identically.

2006 Hp

Thank you very much for the explanation. Then there is no change other than the way Chevrolet is marketing the SSR for 2006. Cleavermodels :flag

Change your Airfilter

Both the Rush and Green filter claim 5 to 13hp, K&N Air Charger "guarantees" 10%. That should give you 440hp bragging rights. :leaving :leaving :leaving

Careful, guys.

From the 2006 press release from GM CANADA for the SSR:

"
A new intake manifold and revised calibrations helps raise horsepower to 400 (298 kw) at 6000 rpm for models equipped with the available six-speed manual.
"
(The press release copy is courtesy of Dan O'Toole. Thanks, Dan!) :)

As for K&N "guaranteeing" a 10% power increase, better get that in WRITING from whomever said it or put it on a website. The dyno cruve that K&N itself sent me recently for the Aircharger claims only a peak 5.5 hp gain at the rear wheels. Since an 05 SSR with auto makes maybe 325 rwhp and the 6-speed makes maybe 340 rwhp, the gain is more like 1.7%

Remember what I have been saying for a long time now: there is a very small gap between drug dealers and those who cater to horsepower addicts. Both tell you what you want to hear and believe. :)
