Doh! Forgot to post the dyno sheet last night... I'll try to remember when I get home tonight.

 

Stock Dyno:


Header Dyno:


Randomn Technologies Cat Dyno:



------------------
2000 Acccord LX V6 Sedan
- Eibach Pro-Kit Springs& Koni Yellow Shocks
- AEM Short Ram Intake
- AEM Tru-Power Pulleys
- Jet Hot Coated CompTech Headers
- Denso Iridium IK20 Plugs
- Forged Racing Hart 17x7.5" CP-035's with 225/45 RE730's
- 15.44 @ 87.87mph (Track)

 

Looks like a kid scribbled on the last dyno sheet...

------------------
2001 Cl-S Black on Black with Navigation
Black Tint all around (15%~45%)
Weapon-R Dragon Filter
Weapon-R Coil-Overs
Koni Adjustable Struts
Comptech Sway Bars
Comptech Headers (hehehe...I got something for you drchang!!)
14.698 @95.977mph....Sears Point Raceway.I think I need a Level 10 Torque Converter!!
Yes, I know I'm going to hell for wasting gas on Civics....

 

that's what I Was thinking...



------------------
Astroboy out...

2001 Acura CL Type S: Comptech: Headers, filter, sways, springs, koni shocks, Volk Racing SE37's in 18", goodridge braided brake lines, AEM CAI (blue), APEXi V-AFC, full kicker system, 13" Brembo's on the way with slotted discs for the rear
1996 Porsche 911 Twin Turbo: H&R Springs and sways, Bilstein shocks, ported and polished, crillo rods, new valvetrain
1995 VW Golf: 1999 VR6 Swap, H&R Coil Overs, neuspeed strut bars, neuspeed sway bars, 2.5" Stainless TT exhaust w/ Borla, 13" AP Racing big brakes

 

That is the worst looking CLS dynos I've ever seen (Is it an Accord or is it a CL/CLS?)

Can you let us know where that was done so we can never go there.

That is the worst header gain I've ever seen. Did the guy buy the:

1. HAI (Hot Air Intake)
2. Lead pully kit with max-overdrive spin-up feature.
2. Exhaust Restrictor (or banana in the tail pipe)
3. Depleted Uranium wheels

That was the same dyno place I took my car, and had shitty results. Both John, and I will be taking our cars to a different location, and get our cars re-dynoed.

------------------
Black/Black 2001 CL-S
Random Technology Cat
RED AEM CAI
Polarg M6 Roadlamps

 

those results are strange. first, a type s dynoing at 191, thats shitty as fuck. second, what the hell is a cat? where do u get it, who makes it, and how much is it? but then his "tork dropped after gaining 20hp. weird ass, oh well, results are good

01' Cl-S Silver/ Black W/ Navi and Spoiler

Comptech Headers, Sways, Springs, and AEM CAI
I've got one of the CLS's from the fast batch.
Lead Foot!

 

The cat is short for catalytic converter. Random Technology makes one for the Accord, which you can modifiy to fit the CL-S. The results of the Dyno is very suspicious. A cat producing 20HP is quite optimistic. 5 HP is more realistic; although I agree with syncivic that the Type S cat is already a higher flow cat than the CL-P. I would await for Spiroh and John to redyno at a more competent shop than the one they were at.

you gonna drive out here after i get my 100 shot of NOS put on my CL? i think that 250>235, don't you? lets do this!

pics soon to come.

 

installed ice man intake and re dyno at 235hp will be re dyno next week at a diff. shop will post it. john

ROFLMBO !

 

I finally decided to do some math on this matter. Assuming a VE od 0.90 for our car I came out to having 350 CFM on our engine at redline.

The flow bench tests numbers I was given showed what would come out to be about 6" - 7" HG static pressue on the stock cat. Going by the somewhat accepted 1 HP for every 1" HG reduction in static pressure the max would be 7 HP.

Now assuming that Randoms cat is not going to be perfect but possibly dropping the static pressure by 50% this could very well lead to a 3 - 4 HP gain.

I'm heading back to Calsonic next week and will try to get the flow bench charts. I also hope to get my car back on their sound analysis dyno to see if the headers do make a sound difference...

 

I gained about 5-6HP. I will redyno, and post the results..then we'll see if the cat is really worth it. To be honest, if I gained 5-6HP, and 5-6Torque throughout the power band, I will be very happy.

how is a sound analysis dyno set up?


------------------
'01 cl-s blk/blk :: comptech headers, comptech springs, comptech sway bars

 

It was a standard dyno but we weren't measuring power. They hooked up microphones, among other equipment, all over the car and made several WOT passes while sampling the sound data at 50kHz. The data is below and a quick analysis is as follows. The 1st order is what you hear. The 3rd order is basically the firing of the pistons. The 6th order is the 1st harmonic of the 3rd order.

The interesting part was why they wanted to run my car. I was there doing a catalytic converter heat cycle stress system (cycling the converter between 800 C and 100 C with 150 CFM flow through it, running like this for days and collecting data). When they saw my car they had just been requested by both Honda and Nissan to perform this test on the car. Honda wanted it for their own reference (Calsonic is one of the premier testing and manufacturing facilities for complete OEM exhaust systems) and to have Calsonic start building them.

But the interesting part was the Nissan request. It turns out that they want to mimic the sound of the Type-S in the new Maxima. I was very pleased and nearly laughed when I heard this.

Anyway, data below.

really? is that common for companies to attempt to mimic other company sounds?


------------------
'01 cl-s blk/blk :: comptech headers, comptech springs, comptech sway bars

 

Not sure, but probably more common that thought of.
