What is your Vtec set at? You should be able to smooth the band out some more.

The numbers themselves are low, especially for a Dynapack. BUT...I was thinking that unless we know what mods the Type S has or another car on that dyno, there is no real comparison. You've never been on a dyno before, so we have no real way of comparing your numbers yet.

Perhaps you are losing compression with the Type S heads? On a Dynojet, I'd expect you to be in the neighborhood of low to mid 280s. But again, every dyno is different and there are still unknown variables. A full bolt on/Tuned Type S made 287 on Jeff Evans dyno IIRC, so don't jump to conclusions yet.

I am going to email Derek and see if he remember what that car had.

Dom going to work with me and see what happens when we raise vtec up to 5500rpm. Maybe that will make the power keep climbing instead of doing a drop from 5000-5250rpm.

Really? I think the higher you go, the more you will dip. Mine is set at 4650 and it's a smooth transition. Obviously every car is different, but I don't think there will be such a huge variation in a similar bolt on car. Did you try lowering it from 5000 to 4900 to 4800 to 4700, etc?

Dom map was set At 4800-
4850. We tried 460-5200 range. While on the Dyno. The car lost power. My car has mdx camshafts. So that could be why ?? Who knows what going on.

I set mine higher (5200) due to dip at 4800. Even that high there is still like a 5hp dip

I think you and me share a similar problem. We are using different heads with larger combustion chambers. So it doesn't act like a normal j30,32, or j35.

For now I think I am done. Just don't feel like adding more parts to it. I will be working with Dom since he wants to tweak the car a bit. But I am going to start saving up for an nsx for my graduation present

I'll have to check you build thread for all your mods. I made 268/225, with a 90mm CC and overhang. If my heads were milled, then they still have a hell of a lot of room to go. As yourself, I'm happy. Car feels good and is quick (I do spray . Still have my J32 sitting in the wings.

Did you look to see what the factory vtec setting is on the mdx. Maybe that could be where the cams like it.

Also Sonnick I think you benefit the most with the lower vtec engagement because of your final drive. You never drop out of vtec

Per acura

The MDX's VTEC® (Variable Valve Timing and Lift Electronic Control) operates the 12 intake valves in two distinct modes. Operation of the intake valves changes to optimize both volumetric efficiency and combustion of the fuel-air mixture. At low engine speeds, the intake valves have low lift and are open a comparatively short period of time during cylinder filling. At high engine speeds where breathing is critical, the valves switch to high-lift, long duration mode to deliver the best volumetric efficiency. The VTEC® changeover point is virtually undetectable to the driver and occurs at approximately 4500 rpm

I've never dropped out of VTEC on any shift since I've had the car. The stock ratios and VTEC point were adjusted spot on in this regard.

Any more info for the mods on the Type S?

The OP never replied. I know his on acurazine since someone recalled his name and said his car had the yellow tinted fogs. I have no idea what his fully bolt on was

Also at the moment I don't really care. Getting married so play time going to be over pretty soon.

Oh **** congrats man.

Like I said before don't sweat the numbers. You got great gains from the dyno time and are only a little bit off of a J35A8. I'd be happy in your shoes.

Let me know when the misses forces you to part out that car :P

Yeah we are going to try to get the marriage license and then just do a simple ceremony right now. Real wedding is next year.

Also looking at cars for her too. So no more modding and probably shift the time table for that nsx.

As a married man, my advice would be:

NSX > Marriage

My personal situation is heading the other way, but congrats Ken! I got a beautiful little girl out of the relationship and wouldn't change a thing.

Sorry still new to understanding our accords, but why does a TL-S have so much more power than our V6? I thought its the same car with just stiffer suspension and luxury interior. From reading I understand it has different heads, but how does that make that significant of a HP increase?

The TL-s has a 3.5L compared to our 3.0L, among other things like higher compression and slightly better cams.

TL's also have a weight issue, they need to be on diets, thus needing more powerl. No replacement for Displacement. Don't worry, these J30's hold their own

They do, but I really wish they came with the J32. Man, these cars would've been on another level.
