I finally got to the track to run the car.
I babied it off the line(i got the 5s tranny) and i am only running 13 psi with 18" tires but overall i had good times. 1/4 mile times were at 14.4 and 14.5 the whole time top speeds were 97 and 98 mph i think if i run it again i am gonna put the stock 15" rims on and turn the boost to about 16-17 and see what happens! I think 13's are easily within reach! DG -------------------- |

Shid air pressure and CFMs are 2 totally different things. The bigger the turbo the more CFM (cubic feet per min) they can push, the more efficient. Its not really a question of pressure, its a question of at what pressure does the turbo stop producing usable air flow and pressure. The CT26 does this until 15lbs just fine, after that it really cant produce the CFMs at a low enough temperature for the engine to use it effectively. At 15lbs a good intercooler should be used. The reason people upgrade turbos is because a bigger turbo can produce more CFMs across the RPM range. If you have a CT26 pushing 15lbs and have a T4 pushing 15lbs its still 15lbs, its still producing almost the same power at the lower RPMs. But if you get the CT26 to around 5000 RPMs where the turbine isnt pushing enough air the T4 can produce more power because its still pushing just as much air and now the engine is working harder producing more power. Thus the gap between the turbos can be seen. This post has been edited by Supersprynt: Aug 29, 2004 - 11:25 PM -------------------- |
