So I bought a wrecked 95 with a DASC and I am getting ready to put it on my 98. I have talked to DA and they are willing to sell me the brackets cables and pieces that are different, but to get the car running this weekend, I need a throttle cable. Does anyone know of a readily available throttle cable that will work?
Also, what are the effects of altitude? I am in Denver at 5,200 ft. Does the supercharger make less boost at altitude? If so what pulley should I get to compensate? |  |  | | 01-25-2007, 07:22 PM | #2 | | Senior Member Join Date: Jan 2007 Location: Ireland Posts: 382 |
i think air is thicker the higher you go up....
thicker air is better......
(i may be wrong my knowledge on this is limited)
you can get a smaller pulley that brings it up to 10psi read around the forum theres a few threads on it.............. | | | | | 01-25-2007, 08:58 PM | #3 | | Senior Member Join Date: Aug 2005 Location: Florida Posts: 2,525 |

Oxygen content is lower in air the higher you go away from sea level. I probably wouldn't worry about it though. You could run a pulley to get more PSI out of the charger but that will also cause the charger to run hotter. I'm sure if you ask DA they would be more than willing to help you if you are buying stuff from them. | | | | | 01-26-2007, 01:46 AM | #4 | | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 |

Yes, and as you get up above the atmosphere, there is no air. We like to call that area..................space  Quote: Originally Posted by 318iS actually i always hated science.... so air is thinner as you go up then.... | __________________

You will need a longer cable and the one I ordered is for the 318ti UK version (with the steering wheel on the right side). It took 4 days to get it. __________________

I'm also at 5000 ft and I run a 9psi pulley with no problems. If you bought your car from a lower altitude, you should release the pressure inside the supercharger's nosegear. I bought mine used off a guy at low altitude, and always wondered why the input shaft seal under the pulley leaked. I opened the fill plug to add some fluid and a hiss came out and a few droplets sprayed out. And this was with the engine cold. So there was a few psi inside the gearbox causing oil to weep out. | | | | | 01-26-2007, 02:59 AM | #11 | | Member Join Date: Apr 2005 Location: Broomfield, CO Posts: 46 |

Do you have any other engine/exhaust mods or are you running 9psi with stock components? | | | | | 01-28-2007, 01:13 AM | #12 | | Senior Member Join Date: Jan 2004 Location: Fort Collins, CO Posts: 290 |
