272/272 will make you more power in the end.

 

how far in the end?

 

how can you say 264's are the best for the stock turbo? We both dyno'd on the same dyno. Pretty much the same boltons according to you sig unless that dyno chart was with different mods.

Here is my graph with 280's:


Here is marks03evo with 264's:

 

that's a big difference

 

You guys have 2 different setups. Marks is good for stock turbo. You would be surprised how well the stocker does at the DRAGSTRIP on 264's. The 280's are for dyno queens and street pulls. I think CBRE used 272's for his 10.9@124.

 

i am sure the 264's would do good but the 280's are better

 

bump

 

I say 272s on the stock turbo.......you'll reep more benfeits with the 280s when you upgrade the turbo........280's for the stock turbo in my opinion are overkill......although its been done.

 

soemthing's definitely different between the two cars. At around 8000 rpm, just before both cars let off the gas, the 264's look like they're actually making more power than the 280's. That's backwards for sure. The 280's should rule the top end, not the mid range as the dyno sheets show. The 280's start to decline in hp at 7000 rpm while the 264's don't peak till about 7500 rpm???? If you want to claim the 280's are better for the stock turbo, then you also need to concede the point that the 264's will outpull the 280's from 7000 to 7500 rpm. Not sure you can draw any conclusions based upon this unusual data.

 

what about the 272's

 

reason for that is because I did not have ARPS installed when they did that pull. The flash bumped up the rev limiter to 8300 but it was not WOT till I hit redline. We lifted throttle at around 7800...

 

272's are the way to go. There is no loss of torque in the bottom end. Search the Buschur Dyno Thread and he explains it.

 

Go big or go home. 280's
