Not a chart the downpipe vendors would like you to see?

so, they put a turbo that would be rated about 550 hp on a car making less than 300 hp and that is all they get?
they blame the downpipe for lack of spool but don't mention the effect of pulling the cat and installing a three inch test pipe, nor the effect of apparently running a stock converter?
Nor mention that the stock ic, stock dp, and stock turbo should run in the 12's if one sprays alky, or puts some good gas in the tank....
C'mon, Guys!
-
The dp did pick up 10 lb ft of torque.
I think those guys need to do some tuning.
-
They need to do more than tunning!.. They need to learn how to parts match.
-
That whole thing is fishy.....they need to learn to match parts and they probably need a new engine if that is as week as it is.
-
Big jump when they changed the exhaust...been interesting to see what happened if they had just pulled the old cat off.
ten pounds of torque on the dp change is almost statistically meaningless, but, they rave how fast the car now spooled....yea h, right
-
who knows, what gas, what chip, tires, knock... look at the power when the did the fuel pump. that thing must have had crazy amounts of detonation. who knows how big of a turbo, what if the converter didnt match?
like steve said, does the person driving the car have a clue what they're doing? are they hot lapping the car? i see no t-stat upgrades too.. but some people say the 160 isnt necessary.
