The blue lines are for my Prelude after the motor rebuild. The red lines are for my TSX after the Hondata reflash.

 

i'll smoke your lude

:troutslap

jk.

nice power on the prelude man.

 

Cool dyno Vwong....what mods do you have on the prelude?

 

The TSX powerband seems much more efficient. to that!

 

I bet you can really feel that vtec switch in your lude.

 

Oh yeah...

The mods in my Prelude are:

- JDM TypeS OS pistons (bump CR from 10:1 to 11:1)
- JDM TypeS camshafts
- new forged rods
- new crankshaft (of course...after the original one split in 2 pieces)
- new exhaust valves
- ported cylinder head
- milled cylinder head a little
- removed balance shafts
- bigger bored TB
- port matched IM to TB
- JUN lightweight flywheel
- Mugen header
- AEM CAI
- Tanabe G-Power Medallion exhaust (removed bottle neck)
- Carsound high flow cat

The motor isn't tuned now. I'm pretty sure I can make more hp if I get something like a Hondata s100/s200 (with OBDII to OBDI conversion) so I can tune the motor. If I go that route, I'll lose the ATTS function which I'm not ready to get rid of now. When I'm ready to convert the car to a track car, I'll swap out the SH tranny with a Base tranny with an LSD, then I'll go with the Hondata to tune the motor.

 

The low end torque in the TSX is very noticeable as compared to the Prelude. Every time when I drive the Prelude, then switch over to the TSX in the same day, I would ask myself if I have changed something in the TSX because it is so responsive in the low end. It'll be best to have the low end torque from the TSX combined with the high end power from the Prelude in just one car. This way I'll be unbeatable on the track.
