Hi...

Is there any HP or spool up difference between these two turbos ?
6262 billet bb vs 6265 billet bb ?
same A/Rs

Thanks,

 

Probobly a little more hp up top on the 65 vs. A little loss
In spool. Not a big difference but the 6265 will make
More over all power.

 

Your butt wouldnt be able to tell the difference between the 6262 vs 6765 so certainly not a 6262 vs 6265

 

The difference between a 6262 and 6765 is huge.

There is a difference between the 6262 and 6265, not that bad but unless the car sees the track all the time, stick with a 6262.

 

Two threads I have seen a few times and quickest I could put together in a timely manner. Now one is a 6265 and roughly makes 700 by 6600, then 6765 is around 700 at 6800!! Thats about 2-400rpms (because I cant tell with the other graph very well) with 2 pretty similar setups. I mean look at the 500whp mark. 6265 makes 500 around 5800, and 6765 around 6100. Your butt will never know the difference of that few hundred rpms. Of course until the bigger 67mm wheel kicks in and says hello to the 800whp

 

Hi Guys

One thing that I have been picking up more and more of late with regard load simulation on Dyno results:

We Dyno all our cars in 3rd gear inertia run to get our Dyno Graphs... (Consistant and repeatable results)

Lot of other Tuners try to simulate load and dyno in 4th gear this allows the car to spool quicker and make more boost (Not always Consistant and repeatable results)

If you compare power and spool on various loaded runs the results are very dependant on the dyno operator so somtimes spoolup can be misleading...

65 will be the larger heavier exhaust wheel and on the street there will be a difference especially wrt boost recovery during gear changes etc and spool in lower gears. There is also an optimal size exhaust wheel for a 2L 4Cyl street car with limited rpm band and I believe the 62 is pretty close to the limit of that...

.

 

Could be what the Dr. ordered for a 2.4 litre though Wonder what a/r sizes we're looking at...

 

The AMS dyno graph is on what turbo?

 

must be the 67 for the hp

 

^^thks mate

 

i would say 6265 since there isn't much difference in spooling, but 6265 makes more power in top end.

 

better off with the 65
