Well, I was satisfied with the numbers. I dyno'd just a short time ago on this hot and muggy Southern morning, a 6-Speed (I/H/P) with 800 miles on the clock; 241 FWHP. Right about where I expected all things considered. I'll scan the plots on Monday and post them.

I'm going back this winter once I have more miles on the car and with cooler weather but I expect to see anywhere from 5 - 10 more. The one thing that impressed me was the torque curve; it is nearly straight from 2000 – 6500 revs. There are a few small dips but with the peak actually coming in at 206@6000 lb/ft, there is over 95% of this peak from as low as 2000 RPM to 6500 RPM. The peak HP came in at 6500 revs.

Now about the RES plate I made, there was absolutely zero gained. In fact the plots were almost identical except for around 3000 – 3500 where it dropped out some. I'm assuming that this drop and regain is what I felt while driving with the plate previously. The kinda surge I got, it wasn't from a power gain per say but really from a loss and then going back up to where it should have been.

Oh well, it was sure fun trying this though!!!

 

wow so you prolly dyno'd around 217 whp stock. Hmmmm so no gain from the DIY RES. Well, so we must assume that there was a design difference between your's and doug's. Any ideas as to what the differences might be? Could it be that doug's design channels the air?

 

Yea, my guess would be about 215 - 217 stock which should be about right for a car with only 800 miles on it. Not to mention that our cars prefer cooler weather...

But about the RES, I would assume they are channeling some how. Now the question is, will we ever see it??

 

Sweet. Thats a 13second car. I dont think you will have any problems dipping in to the 13s with the headers, and intake.

Thanks for the update, would still like to see the sheet if you are able to scan/takeapic of it.

 

I don't have a scanner at home but do have several at the office, so I'll have it posted first thing Monday morning.

 

thats about 300 at the crank, why doesnt honda jus do that in the first place???

 

cost, increase in insurance premiums for potential buyers could sway consumers to another car, etc.,

 

i have an idea on the zero gain from DYI...im not smart enough to understand the whys,like you would be steve, but i belive it's something to do with the EGR channels he(doug) mentioned a scenerio like blocking them off ,or some of them off, or resrict them ... seemed in passing...but your design makes there paths longer...am i way off here not sure ,mull it over

 

now lets see if you can hit a 14.0. any plans on going to the strip?

has anyone run a 6speed w/ headers at the strip?

 

It could be but I don't see how it would be. EGR is just for emissions. I can't see how the length of the exhaust recirculation would make a difference in power, but I guess anything is possible.

 

Yes, this fall once it cools down a bit...

 

SWEEEEET!!!!!!!!!!!!!!!!!!!!!!!!!

Very impressive!!!! Thanks for keep us up to date!!!


As far as the RES goes, I have said it before, and I will say it again, when I see it, I will believe it!!!! And please don't post the ONE pic of it from that auto show. I wanna see it on a car, and I wanna see the dyno from it. Then I wanna see a warehouse full of them!!! Then I wanna see a website where I can order one!!! Then I will believe it is real!!!

 

 

i dont think it would sway enough, but they should atleats offer it as a dealer installed waranteed item. Liek TeRD. Call it ARD.

 

I’m confused, aren’t these numbers a little disappointing?
I thought stock Auto’s were getting around 200-HP and 232 with Headers.
Stock 6-Speed’s are getting 217-220, so 241 only shows a 21 HP improvement.
And that’s not even counting the Intake and Pulleys.

I know it was HOT out, but shouldn’t you be getting around 250-255 ???

last time i went to the dyno i put

241HP to the wheels
247lbs of torque to the wheels

 

“Funny Gas” doesn’t count.

Shawn S

 

Shouldn't the numbers be higher? I put 231hp to the wheels without headers. Should I expect these type of results with the headers? I was thinking that I would put out around 260hp with the headers.

 

Ppl, apparently you've forgotten how hot and sticky southern mornings can get. LIke scalbert said once the motor breaks in a bit more and once it cools a bit he expects to see 5-10 more HP. Relax

 

dont forget dyno variances

 

Thanks Zapata and typer...

There can normally be a 2% - 3% gain once the engine is broken in completely. Not to mention the fact that our cars really prefer cooler air, the ambient conditions were about the following: 86F, 29.21 baro and 72% RH. The IAT was reading 150 at times!!

With a broken-in engine and coolere temps we would be looking at mid 250s. But there is another issue as typer mentioned, dynos vary in their numbers...

 

Below is the image and a link to the full sized scan. The blue is with the plate and red without.

Nice work Scalbert!

Please don't mind the people doubting the low numbers.

Until they have had their car dyno'd on a cool day and then again on a hot day and seen the graphs overlayed, they just can't understand how BIG of an affect the temperature has on our cars.

Also just for the record, which gear did you dyno your car in?

 

We ran it in both 3rd and 4th with 3rd showing slightly better numbers. I was surprised about this as I expect 4th to show better. It was down a few ponies at about 238.

The above charts are 3rd gear pulls...

 

Do you remember the gear ratios for 3rd and 4th off the top of your head?

 

GEAR 1st 2nd 3rd 4th 5th 6th Reverse Final Drive

Ratios (:1) 3.933 2.478 1.700 1.250 0.976 0.771 4.008 3.286

 

I’m not “doubting the numbers” or accusing anyone of trickery.
I’m just somewhat disappointed with the results as compared to the 220 range numbers I’ve seen posted here for STOCK 6-Speeds.

Shawn S

 

LOL, that's what I'm trying to explain! Hot weather KILLS performance on our cars!

I've run .3 to .4 seconds SLOWER in the 1/4 mile during the summer months after I added an intake than when my car was stock in the cooler spring months.

If you took a stock 6spd and dyno'd it on the same day and the same dyno as scalbert did it would probably be putting down 205-210 hp.

That's why there is nothing to be disappointed about. Now if scalbert dyno'd with 75 degree temps and 30% humidity, then we would all have cause to be a little concerned but even then his engine still isn't at its maximum potential until he puts on some more miles.

Also, the stock 6spd that put down 220, did have more or less than 800 miles?

 

I expect my car would have hit 215 in stock form. If so, a 26 HP gain at the wheels is about right. Most automatics dyno'd around 200 stock, then in the mid-low 220's with I/H. There are always exceptions though...

Give me an extra 2% once broken in and the number gets closer to 250 FWHP. With better weather, that number easily climbs over the 250 point.

 

Dynos are supposed to be run in the closest to 1.0 gear ratio correct? Else your numbers will be skewed? Just what I remember hearing/reading.

I ran my dyno in 4th...

 

That is very true, but 5th gear is the closest and would take it up too high of a speed. But I am still curious why 3rd came up higher than 4th, I would have expected it to be lower.

 

Good try Scalbert, I wouldn't give up though, follow some of the advice of typer.

 

sorry to hear the numbers on the RES...I guess it will be a dead issue for the Mystery Mod RES build...nice work on the RES piece anyway...

 

Shoot, I haven't forgotten. Try putting a suit coat on down here!

 

To tell you the truth Scalbert....I dont know if the auto CL even makes 200whp in stock trim....I'm making 227whp with IHP...in about 68 degree weather...not humid.

 

That sounds right where I have seen others. Although Comptech advertises 27 WHP gain, no one has ever gotten that. Most see between 15 - 20. The intake and pulleys may add another 7 - 10 total, bringing the ante up to about 28 WHP; maybe a little more.

Add about 20 - 22 hp for the difference in transmission and that would be nearing 250 FWHP on the 6-Speed. Now I know that once the engine is broken in, Mobil1 is added and there is better air, there is another 2% - 3% to be had (maybe more). Which puts it realistically right where it should be. At or near 250 FWHP.

 

I was at 192hp stock. With all my mods I was at 227. So was Acura Crazy.

Here is something really crazy then, I made more power stock in my '01 CL-S with a malfunctioning IMRC...

 

IM sure it has to do with location. I still get good times at the track.
