Dyno: CT Supercharger 3.3 pulley and K-Pro dual
Hey guys,
This was emailed to me by Doug from Hondata. It also appears on one of the other forums. I figured I should pass along the info
Preliminary results from testing this morning.
04 MT TSX:
- 06 TSX intake cam
- 06 TSX TB - 64mm
- 45 Degree VTC cam pulley
- Hytech headers & exhaust
- High Flow cat
- Injen intake with (very) dirty air filter
- CT supercharger
- 3.3 pulley with 1920mm belt
- VTEC point 3000 RPM
- 7 PSI boost
Notes:
- Torque is wheel torque not engine torque. Engine torque is 225 ft pounds
- Red line dirty air filter
- Green line velocity stack no air filter
My TSX will be at the dyno day tomorrow where I might try a 3.15 pulley if there is time.
I now have a good base map for those interested. The car is very smooth and very fast. This is not surprising as it has 75% more power than stock.

I wondered the same thing:

I thought to get the most accurate whp reading on a dyno means pulling in a gear with the closest ratio to 1:1. For the TSX, that would be 4th gear (1.088:1).
I've done a few dyno pulls in both 3rd and 4th in the same session, and my numbers in 4th were always higher by about 10%.
Very nice numbers, Doug . Correct me if I'm wrong but you're also still running a stock clutch/flywheel, right?

Doesn't the CT SC drop the vtec enguagement point to 3K? Can you use k-pro or something similar to raise that to 4.5Kish or are you stuck with it at 3k? That's one of the things that's been keeping me from getting a SC for mine.
#32
Yeah, the CTSC does drop Vtec to 3K. However it is a Vtec window based on how much throttle and manifold pressure there is.
Below 3K, you are always Not in Vtec
Above 5K, you are always In VTEC
From 3K-5K RPMs you will be in VTEC depending on how much you are on the throttle.
And with K-Pro, you can set VTEC where ever you want. From what I've heard, having it at 3K produces the most power though. So you could change the Vtec engagement point, but you will probably make less power.

I second that. I did not know it was a window. I have the kit (may put it on in 2 or 3 weeks) and do spend alot of time on the highway. I am typically under 3K even at 75ish mph.
#38
Yeah, with the gearing on the Auto. 3K RPMs will be about 87-89 mph on the freeway. That's my cruising speed if there is no traffic.

For the VTC machining, I'm not sure about that one. Ideally, it would be nice if someone ended up with an extra VTC. That way you could get it machined ahead of time and then do the swap without the vehicle having any down time.
Then that person could sell their unmodified VTC to the next person.
1) 06 TSX intake cam (Most aggressive Honda OEM intake cam) This is stock on the 06 TSX, but not on the 04/05
2)Modified VTC to allow 45 degrees of CAM advance on the intake
