the disadvantages of the set up is cost and installation effort and its limititation to 4.5 liter engines and smaller, or more accurately said, 300hp flywheel hp and lower to gain the 4-6% we have seen on most all dyno runs.
You basically, are putting the battery and to a certain extent, the alternator, to work which is dead weight usually, to power something to get some additional hp.
there is really no differnce between a belt or turbo driven supercharger and this device, albiet the eRAM is only in the sub-1psi gain range, and "normal " superchargers are 7-28psi gainers!!
its a bolt on device with a bolt on device price tag. thats really sums it up.
we have seen as much hp gains with the eRAM as we have seen bolting every type of HP gainer on our race car since it was a street car. the list includes:
cams
intake
exhaust,
headers
heads
compression
displacement
fuel regs,
throttle bodies
intake runners,
etc etc.
we went from 175 rear wheel hp to 294 rear wheel hp with these mods and along the way, the eRAM was good for a 7-10hp gain. trust me, for $300 vs some of these efforts, its a good deal

Just to make it clear to everyone in this thread.
Mark Kilbort is associated with E-Ram. He is not an independent voice in this conversation. So caveat-emptor when taking his advice on this product.

People that know me, know that ive been very up front with the capabilities of this product and constantly am providing more and more information to help my fellow porschers to get more performance out of their beasts.
This is just one trick that helped me with my older racer when it was in the 300hp range.

That is great.
I just wanted to point out to the group that you may have an incentive to help sell the product. Your relationship with e-ram, by definition, makes you a biased source of information in this thread.

Understood.
Im not lurking here for sales efforts, as the 930 porsche group is not a target for marketing .
If my efforts help someone on this list redesign an air box, or intake system and they get some gains, im happy.
Here is a recent magazine that took the eRAM to a dyno without any of our help or assistance. notice the divergence in the dyno Hp curves.
the really interesting thing about this kind of mod, vs others comparing baselines and improvement runs. we can do a run that is greater, do it again and pull the plug on the eRAM midstream, and watch the HP curve fall back to baseline.

Thats all from me

Mike,
Thanks for dropping in. I have always been an "Out of the box" kinda guy anyway. I,m pretty close to placing an order.

Thanks for the good idea jhunt. I'll do it if I get the device. Mike is right about the coast if it nets me 300 rpm drop reaching max boost.
