New dyno numbers/pulley comparison
Just thought I would share my latest dyno numbers with everyone. The graph shows the dyno that was done in December and the one that was done today. Previous mods were Borla x pipe, green drop in filter, catless down pipes, and a 2.31 upper pulley. I decided to buy the 2.175 upper pulley from Kong Performance to get an extra pound or so of boost and get it retuned to make sure everything was still safe. Previos numbers were 622 hp and 680 tq. Then just with the switch to the 2.175 upper pulley the numbers went to 654 hp and 732 tq. I can honestly say I didn’t expect to pick up that much, especially the torque. Very, very happy with the results and I would suggest anyone doing an upper pulley to just use the 2.175 over the 2.3. So 654 hp and 732 tq with super simple mods and tuning.

Thanks for sharing. I have the 2.3 upper now and have the 2.175 sitting on my work bench. Can you confirm that the 2.175 will bolt right on to the hub without any modifying or machining of the snout. Greg from Kong says it will bolt right up but it seems like lots of guys say the snout needs to be modified?
Congrats on the killer numbers! |

If anyone is interested I have a brand new 2.175" pulley, never installed that I'll let go for cheap, PM me for details.

So just Borla x pipe, drop in filter, catless downpipes, and a 2.175 pulley and you're making that power? No E85? 650+whp is impressive with just those mods.

Correct. The car was completely cooled down in between runs, so it was a good pull, but 650 whp on a manual car with my mods is about right. I know with just an intake people are seeing high 500's and with a tune into the 600's. I think the 2.175 picks up 3-4 pounds of boost so that combined with the downpipes should make another 50 pretty easily. Most other dyno's I've seen on here with similar mods are making similar power. I was expecting to see 650, I was more impressed with the torque though.

What was the reason you went with the catless downpipes instead of long tube headers?

Can I ask why u did the upper pulley instead of the lower ?

$400 is what i paid for lower pulley install, and $550 for parts.. |

Most of the time people do it because its cheaper, and labor is cheaper too, but the lower is better IMO becuase your getting a ATI Damper which is better than OEM!

Because they work, cost less and are a lot easier (less expensive if you pay) to install. I made 742 HP & 803 TQ using the Norco pipes.

Thank you for sharing - great comparison! Congrats on the nice gains

What belt are you using? I assume you can use the same belt for either the 2.3 or 2.175 pulley?

Interesting. I'm using the Gates HD 080855 since that is what Joe at Cordes recommended. Thx man. Have you taken yours to the drag strip?
