  5. E85 doesn't have the same knock characteristics...

    E85 doesn't have the same knock characteristics that gas has. Gas will tend to knock, make noise, and set off sensors before something terrible happens. E85 will knock, but does not give as much...

    HKS 8555 is rated at 918 CFM
    Rotrex C38 91/92 is rated at 1205 CFM
    Vortech V3si is rated to 1150 CFM

    Don't quote me 100% on those conversions, both manufacturers use some odd-ball flow rates...
  7. The biggest thing we've found is how much more...

    The biggest thing we've found is how much more efficient the Rotrex is. If you notice on the graph the Rotrex is actually making less boost across the board until you hit about 7000rpm. It makes...

    The newer cars measure EGR/Airpump efficiency by looking at the o2 sensors. If you have a dying sensor it could be warming up slowly causing it to miss the lean running spot when the motor warms up....
  9. M54: The headgasket thickness is different between the...

    The headgasket thickness is different between the two engines. You would have to use atleast a .070 thick gasket on the M54 with those pistons to get a regular compression ratio. I see no reason in...

    We are not, and have not yet looked in to it. I feel that there isn't a big enough market for it yet and the prices would have to be high. I'm also not a fan of hacking up turbo housings and just...

    The stock compressor wheel design looks more modern than their billet wheel. Yea, the billet wheel is pretty but alot of manufacturers are moving towards more blades and cutting out those small...

    Ouch.

    I haven't seen a 335 break an axle yet, which part broke?

    I just wanted to touch on a few points that have been brought up about both kits. I do not say the ESS kit is bad in any way or want to drag them through this mud for any reason. I do however want...

    Do not get rid of the VANOS on the S54. It's an amazing thing, and if you've ever looked at the stock cam profile the car will be dead for 70% of the RPM range, and even then may not be able to...

    The best fix for this would be to run a solenoid as close to the nozzle as possible. Check valve systems have a bleed down delay which will cause the meth to be blown out.

    Different piston design/makeup.

    M52 pistons are made at a height for a headgasket twice as thick as the M54.
