Just thought I'd share my dyno graph and a few pics to everyone with my new setup.

418whp/343wtq @18psi on e65

  • MercRacing TVS1900 Kit with Aftercooler Kit
  • Stock motor
  • GearX 1-4, Synchrotech Synchros and Sleeves, WaveTrac LSD

If any of you guys have questions about my setup, let me know.

Looking good!
How is the short ram intake doing? I guess with the aftercooler it might now matter too much.
I switched to a CAI after getting like 140 degree intake temps.
Do you have an aftermarket IAT sensor?

Yes, aftermarket. I believe it's an AEM IAT sensor IIRC: AEM IAT

I haven't played with the intake yet. It has been discussed with MercRacing. I might try and fab up a CAI in the future (got to relocate the battery first).

Also planning on upgrading the water pump for the aftercooler kit. My IATs are usually 20-30 degrees above ambient.

It was cool being there to witness this car doing these number in the worst conditions possible.

Man thats a lot of boost!! Only thing I dislike about SC set ups. The boost to power ratio.

I watched your vids though. You got a nice thing going there(y)

I love SCs for Honda builds! Can the stock motor really hold out on that much boost, even with E65??

We really don't know but, I know @15WhiteSi is trying to find out. Really crazy, but the guy doesn't care if the motor blows as long as we find the limit.

It is probably the one downside to it, but the pros are much more.

yea, I'm kinda curious to see the cfm flow rate. Remember, I can have a smaller blower and push more psi for smaller hp/tq numbers. I would like to do a comparison between a turbo and supercharger with similar cfm to see which makes more hp/tq at the same psi.

Appreciate your support!

yea, same here. I used to only run turbo, but I really enjoy the sc. I mean..... so far i've see a few youtubers pushing more hp/tq and boost on stock more.

Just a few updates. Got some new wheels, added a bigger water pump for the aftercooler, and relocated the battery. Enjoy!

Got my car retuned today. Changes since last tune: 8th gen crank pulley, 3.0 s/c pulley, water pump and reservoir upgrade for my air to water cooling system, and went back to OEM tb.

New numbers: 450whp/356wtq. Same psi but on e75 vs e65. Mods made a huge difference!

i was on the look out for this post. LOL

joking aside, you caught me late night working. This is a huge step forward. It shows that with a few minor mods, and really better weather this setup can put up some serious power and torque.

congrats to you man. I know you've been putting alot of work towards this build. it's a monster

How are you liking switching back to the OEM throttle body? Is the part throttle drivability better around town now?

It's definitely better! Now, with the ethanol and bigger injectors (ECU does background air/fuel calculations), there is still a SMALL bit here and there, but WAY better than it was. IMO, bigger TB is not worth the trade off until Hondata can fix the issue.

It's not an issue that Hondata can fix. It's a circuitry issue. The IC that controls the TB motor is rated for 5A. The stock TB pulls 4.9A which is obvs within spec. Now the ZDX TB pulls 10.4A on that same circuit that's only rated for 5A, which is twice as much current (NOT GOOD).

After reading into this more, I'm really in awe that anyone runs them. I'm no electrical engineer, but that just seems like it's asking for electrical gremlins to run the larger TB. Especially, like you're saying, the juice just isn't worth the squeeze. The gains just aren't there for the potential issues it introduces.

I agree. Maybe just getting a shop to bore out the stock TB will be good. Also, maybe somehow change the circuitry of the TB. We did switch the a few of the components, but nothing helped. Maybe I just have to look into more.
