SFPH - Dial_Ur_Boost Pulley Units for Cobalt SS!!
21 - 40 of 50 Posts
No kidding. Blowing hot air into the engine will kill power..considering dyno's don't have blowing air on them (other than fans, which don't work like real air). I'd still like to hear from SFPH tho about this, as they seem to be ignoring the question on the redline forum, which is why I posted it here too.

If I were to upgrade my SC, I'd go with Psi-Fi's "piggyback" system. It re-tunes the computer, has new injectors so more fuels goes into the system so it doesn't run EXTREMELY lean with the extra boost, and a new pulley. And it has been testing for about 2 months now I believe. Tonight they are having a public showing of it and demonstration (I live like 5 hrs away by plane tho ). I would trust that set-up much more than a simple pulley swap as it seems to me they have done no research into the engine and the problems that may occur by using a smaller pulley (if they can get anything to happen in the first place).

I would trust that set-up much more than a simple pulley swap as it seems to me they have done no research into the engine and the problems that may occur by using a smaller pulley (if they can get anything to happen in the first place).I believe someone on the RedlineForums.com website posted that they gained 3mph in the 1/4 with no other changes besides the pulley. 3mph is nothing to sneeze at, thats a decent gain for this price (3mph equates to roughly 30hp at the wheels)
I tend to believe track results over everything else. Granted, one test is not the end all, be all of tests... but I think it shows that the product deserves some more testing from other individuals before going overboard condeming it.
Also, most Lightning guys get HUGE gains from simply a pulley change. I dont think the S/C on the Cobalt/Redline is huffing past its efficiency post at stock boost levels, so this pulley _seems_ to be a decent modification.

I have no idea what their website is. www.psi-fi.com maybe? I just read the www.redlineforums.com forums. Granted the info may be a little out to lunch at times, but occasionally you get some decent info.
XeroState, normally on any Forced Air Induction engine , you must first take the necessary precautionary measures against excess heat intrusion into the engine , by making a few changes. One of them is changing the factory restrictive air intake system, to a less restrictive system, to let the added air flow into the engine.XeroState said:
Secondly, you should either (dependant upon size of smaller SC pulley) change the stock sparkplugs over to one range colder and close the gap, to lower cylinder temperatures. Thridly, is is like I mentioned in the Redline Forum, you must check your Air/Fuel Ratio numbers to make sure they are well inline of not being pon the Lean side ( 11.5 to 12.0 )
If after making these changes, then no increase in boost pressure is present, then a Boost Bypass is needed to allow the boost to increase (but at a safe level). Anything over a 2 lb. increase in boost, should have a Safe Computer Tune, to make sure the vehicle is not leaning out, that could cause, not only excessive knock retard, but also severe detonation and grenading of the engine.
However, a couple of people out in Texas have already done these modifications to attain 2 to 3 more lbs. of boost and are not having any problems so far. Also, we do not have any Dyno Results to report , but there are a couple of companies who have already purchased our pulleys that are having Dyno Tune Sessions in the next couple of weeks.
As soon as these results are in, we will post them accordingly. Hope this helps, as we are certainly not selling "Snake Oil" to the Supercharged Engine owners, just to make a "Quick Buck". Instead, we are offering a quick solution to making the needed horsepower levels, each Enthusiast desires to have.
For the past 7 years SFPH has been coming out with newer products for all Foreign & Domestic Supercharged Engine Owners and we have not failed in our quest, for them to achieve the horsepower produced by our smaller supercharger pulleys, with the proper tuning etc. to make this happen.
You might be limited in running higher levels of boost at this time with the ECU limited it, but shortly there will be several companies offering a solution, as to how to overcome these barriers and give everyone the performance they want.

Well we will see and i would like to get more info on your stuff and i will be looking for some more data and with a dyno read out. O and will you guys doing a long term test on a SS or Readline to see if there are a problems that may ouccur? Thanks.
