Looks great, can't wait to see how it runs and performs. DEFINATELY cant wait to see how WOT sounds. I only suggest you get some video of runs in local traffic, I want to see the looks on peoples faces when that bad boy spools and the twins come alive, definately impressive. QUESTION, do you think it wise that if this going to be a long term investment and plan on using it as a daily driver to invest in a Renntech transmission or do you believe our transmissions, stock internals, driveshaft and gears will be okay with min. boost or under or at 6lbs. My Visa Platinum is waiting your answers
6 lbs and below will be fine for everything. Hell 10 would be fine, but the way everyone would drive it would eventually kill it....
Wow this is impressive if true, traditionally centrifiguals have been most efficient and they had intake temps above ambient. I cant imagine what the instant neck snapping torque is going to feel like on a AWD SUV. When when when ?????
It goes up $100.00 everytime we ask-LOL I think they are working on the final numbers should be out soon
it's going to be tough to decide between this system and the rear-mount turbo from PPP.. glad there are some options!
Have you guys seen this supercharger: http://www.300cforumz.com/showthread.php?t=10803 Same kind of concept, just not nearly as integrated looking. It's from a guy in Australia and I have no idea if it's commercially available at all, let alone in north america. What's interesting is you can see how/where the intercooler would fit. I'm assuming the I-charger is similar.
I missed that part! This statement by GSM kinda defies Boyles law... Usually I allow 10 degree F increase for every pound of boost, so a 6 PSI boost would be a 60 degree pressure side manifold temp increase. It is impossible to attain ambient temp with an increase in pressure. Then further downstream to use around 8 to 1 final compression would be 140 degree increase in cylinder temperatures minimum over ambient. (Minus any decrease in temperature from the effects of the Latent heat of Vaporazation caused by the injection of fuel at the ports) Unless the location of the fuel injectors are ahead of the compressor and the of fuel is used to cool the compressor also . :unsure: J
We will be testing in the next few weeks and coming up with pricing. Target pricing will be in the 6000.00 range on the base kits, look for us at the spring festival with units on the vehicles. Scott
I have been reading this thread with interest, and done some research (takes me back to my school days) Boyles law is defined as P*V=K Where P= Pressure, V= Volume and K is defined as constant. It is also written down as P*V(before)=P*V(After) which means the Pressure*Volume before compression equals the Pressure*Volume after compression. These equations work at a constant temperature. I don't think this will help working out the increase in temperature due to compression in a supercharger. The equation that is more applicable is the Combined Gas Law. Which states that (P*V)/T=(P*V)/T This gives the relationship between the temperature before compression and the temperature after. If you throw some numbers into the following online calculator http://www.1728.com/combined.htm it shows increases in temperature due to increasing pressure but no ware near the increases you were talking about. So it looks like it is possible. Boyles law is defined in Wiki at http://en.wikipedia.org/wiki/Boyles_law Combined gas law in wiki at http://en.wikipedia.org/wiki/Combined_gas_law
Excellent discussion, now you also have to add the Ideal gas law, theromodynamics of compression, and the efficency of the supercharger. In a perfect world, with a 100 percent efficent blower maybe.. My quess is they are using a Harrop blower so that unit as well as any other cannot claim to be 100 percent efficient. Then the heating value also changes with the increase of the ambient temp. Thats why I use the "Old School" figure of 10 degrees per PSI it works out pretty close real world. Until you get to about 2 atmospheres. Unless they have a brand new undisclosed design blower
I did say that it was possible to do! I am a little confused, earlier in the thread some one posted that the charger is a Wipple style. This would imply a more efficient unit but I could be wrong.
I would imagine it would keep the battery warm and per long it's life and improve cold starting. BMW have been doing it for years on their cars, they have a padded cover that encases the top and the sides.
Mine has it Interestingly my coolant tank has a clear top Thats the first 08 I've seen with a black top
