OK Guys just checking if any of you guys will be picking up the comptech supercharger. $4500.00 is steep but i would love to have 300 whp

UNCTYPE-S

im sure there will be plenty of people buyin this when it comes out.

flnsx

I am going to buy one for my A/T.

WiLLs TypE S

can the 04TL get 300WHP with the supercharger..coz the CL-S can get around 260-280whp with the supercharger. So I'm assuming close to it?

I am going to buy one for my A/T TL as welll....

I spoke w/ CT thru email yesterday and they said "before the end of the year" the charger will be out. So plan on early to late spring.

I guess there is no need for the extra power during the winter months, so that's a wait I can deal with.

There is no way an Auto TL will ever see that much whp.. that's for darn sure. I'm just looking forward to the bump in torque across the band...

Shinj1EVA

So negative. I'm sure it's MORE than possible w/ a supercharger and possibly a few other minor mods.. 300whp isn't that high that it's unobtainable with the TL engine.

WiLLs TypE S

Hopefully, because if it is...I give the TL props for having a FWD car with 300WHP...but IMO I kinda of think automatic is kinda of hard to push out 300whp IMO. But if it does Props to Comptech!

GaleForce

300whp? That means the Supercharger has to add like 80whp or even more. I doubt that will happen, especially considering they can't go all out on the SC because of the engine's high compression ratio.

Shoot2Thrill

What chapter did I miss that says the M/T and especially the A/T are even remotely robust enough to take a extra 20 WHP and survive in real life.

The 2nd gen CL/TL chapters. They can be found here: https://acurazine.com/

With manuals its possible. Just takes extra time and tuning. Maybe a smaller pulley.
Is Comptech going to recommend a built up tranny to handle the extra power?

It should be a 330-350hp car I would figure.

EmuMessenger

Minor hijack, but I still cannot get used to that acurazine stuff!

caball88

4500 is kinda steep but does the warranty get voided? i know some tuners are associated with the car manufacturer and modding with their parts will not void the warranty. if the comptech S/C can be installed while retaining the warranty then it might be worth a consideration.

1SICKLEX

caball 4500 is very, very cheap for a F/I kit

caball88

yes but this is a supercharger setup which is less complicated then a turbocharger. i realize the prices for F/I and its about where it should be. i came from a bmw forum and 4500 is cheap for F/I. on the beemers it ran like 8K for stage 1 turbos. but it was much cheaper for S/C. especially since the S/C for the 3rd gen is pretty similar to the previous gen TL/CL which share the same motor.

1SICKLEX

MrGQDieselNY

WHP I assume is HP at the wheels? so thats like 80-100 extra HP? for $4,500...hmmm

so what would the BHP be? like 350?

caball88

350 is a little too much. on the previous gen TL/CL it made between 40-60hp. so on the 3rd gen it would probably be about 330hp tops.

JetJock

Don't start whining about your transmission when you put a supercharger on your car. Acura never intended for the engine to develop that much power so kiss the warranty goodbye and start waiting for the tranny to fail....is it really worth it for some extra power??

Aquineas

Hmm.. where is this info coming from? The Comptech Site lists it as still "under development", with no further info available. As others have said, if it's true, it's a decent price for the power, but I'm skeptical until I see results. The tranny worries me a bit also..

Pug

What will the compression rise too? Can the stock pistons handle it?

Nitrotiger

Stock compression will be fine there are many CL/TL owners out there spraying 100 shot of nos all day long with no issues. The auto tranny wil be a nightmare just like the old CL TYPE S unless they made big improvements to the tranny from the earlier years. When i had my TYPE S i went through 1 tranny at 26k I have the 6 speed so im not worrired maybe need a clutch thats all

AcuraVic

Yes I will be getting that !!! However, If it voids any of my warranty the answer is NO!!

I talked to my Acura techs and they will install it because they are a vendor of Comptech parts but they are not sure about the warranty issues to date.

Chemmech

I have an 03 TL-S, I have the S/C with an Intercooler, fuel reg. upgrade, e-manage (on the way) and 9 lbs of boost with the hbp and larger s/c pulley. So far I've had no problems with the car .

Aquineas

But there's a difference between the 11:1 compression ratio of the 2004 vs. the 10.5:1 on the previous incarnations. I don't know that you could make the assumption that they would behave the same under boost, because it would be much more likely to detonate or pre-combust in the 04.

flnsx

I hear you about the tranny problems. I will only buy it if the dealer will cover my FULL stock warranty with the supercharger.

ALSO, make sure you get it in writing.

If they won't cover your transmission then I would think long and hard if I were you. Also check your bank account balance.

caball88

what did you dyno the car at? and did the dealer you get the car from still honor the warranty?

Chemmech

I'm going to have the car dyno'ed this week, I'll let you know soon. Dealer knows nothing of my mods. I will probably put the car back to stock for any waranty work, new transmission etc.

The car is probably making somewhere near 450 crank hp. At the wheels the same setup yeilded 369 whp for a CL-S 6 speed. Go over to acura-cl.com and do a search on Scalbert or Chemmech.

ensley696

Does anyone know if the warranty was voided on previous gen TL/CL's after installing a SC?

ITL

Well, that's probably because, according to your profile, you're only two years old. It's hard to abuse a car if you're not even old enough to drive it.

1SICKLEX

Having met Scalbert and seeing him work on his car at a dyno day, the dude knows his stuff. He does not have a stock kit. He has done many upgrades himself. And acknowledged he is at the limits for traction. His CL-S is one of the fastet and highest rated in terms of power. A real beast. But he did too upgrades to the stock S/C.

In both Car and Driver and Sport Compact Car, they have tested the S/C CL-S and stayed in the 14s for the 1/4 mile and 0-60 times barely dropped.

1SICKLEX

Here is what he wrote on my website concerning his custom set-up and a dyno graph. Scalbert is the coolest guy around.

or those of you that know me and the process I have been trying to build up this car, I thought it might acceptable to mention this here. Although this is not concerning a Lexus, my wife does drive one and so does her father.

Anyway, I finally got to the dyno last Friday with my blown CL-S6 and the numbers came out to just about where I had anticipated:

369 WHP
310 WTQ

This was with my custom upper intake manifold/intercooler that some of you have seen. It was done with about 7.5 PSI boost.

The red line is a plot prior to installing the IC which was done last winter. This was with 5.5 PSI boost. I will be doing a bit more tuning with it and maybe a bit more boost. I'll probably wait until fall/winter to go back though for a bit cooler temps as it was almost 90 out at the time. I believe 400 WHP is in reach and the final goal as this is already too much for this platform. The gearing of the 6-Speed and trying to send it through the front wheels makes traction difficult.

Thanks everyone, it has been a fun project. Particularly since most of it has occurred since the birth of our twin daughters who are now 10 months old. In other words, it has all been mostly a blur.

The details of what is on the car:

Comptech SC with a pulley combo which nets about 7.5 PSI mean.
Comptech Headers
King Motorsports Ported TB
Greddy E-Manage with a Custom PnP Harness
Lastly, a Custom Upper Intake Manifold with an Integrated Intercooler using a Spearco Core.

I do have the TechEdge Wide Band A/F monitor in the car which has proved to be invaluable.

I am going to try and hit 400 WHP as there is still some room left. At this point though, it is really just academic as the power is worthless with this FWD chassis. But the car is smooth, comfortable and easy to drive with one of the best manuals I have driven and an absolute ball on the highway.

I really need to get to the track though as I'm itching to get some times in. I'm not expecting blistering ETs but decent traps should be possible.

1SICKLEX

Thanks, the upper intake/intercooler was custom. I did the CAD work and had a local machine shop do the work. This took me about 7 months to complete starting with rough drawings, moving to card board prototypes and then on to the AutoCAD work. I did get lucky though, the base plate which mounts to the stock runners matched up perfectly the first time. This was the most critical point and after that it was a breeze.

The SC kit is the standard Comptech system but with modifications. In base form it only made about 4 PSI boost. They had an upgraded pulley with raised this to 5.5 PSI but supposedly will void the blower warranty. Knowing where I was going and knowing these blower well; that did not concern me. I had another shop then make a custom pulley to get me the boost I am now seeing.

The only other custom piece was the GReddy E-Manage. They have no specifications for the Honda/Acura J-Series so it was all new territory. I tested it on the bench with a scope first. Then, with the addition of the custom PnP harness I made (the connectors were next to impossible to source in single piece quantities) it was just a matter of trial and error to get it to work. Right now I am extending the injector pulse width directly; taps into each injector signal. It also has the ability to retard timing (intercepting each coil signal, 6 in total) which is currently installed but no retard is applied.

As for the VTEC change over, the only thing that occurs is a slight surge in power. You can actually see it on the chart occurring at 4800 RPM. I am not using the VTEC control of the E-Manage as I felt the engagement point was ideal. I drop down to about 5k revs after a shift which is still above that point. Plus, there is still plenty of torque below that point to motivate the car. The VTEC in this car is a three lobe system or five lobes per cylinder since this is a SOHC engine.

1SICKLEX

Of the CL's in the various forums and from what people know, yes, this is currently the most powerful including those running nitrous.

However, this will be short lived though. Ramanan (allmotor_2000) out in California is finishing up his second turbo kit, this time using a bigger compressor and more attention to detail (not to mention the GReddy E-Manage which I made the harness for him). I suspect he will make about the same numbers as I did on less than 6 PSI boost. When he turns it up I can see him easily cranking out 400+ WHP.

That is about all we can expect to do on this engine considering the stock 10.5:1 CR. With some engine work and lowering the CR we could potentially make 500+ or more. But it is pointless on this car; there are better platforms to make massive power with.

The one part I love about my car right now is the torque curve; I couldn't have hoped for a better one. This is what makes this car such a joy to drive on a daily basis; the power is there whenever and wherever you are in the rev band without any surges, etc.

I should have been more clear -- there is no way it'd see that power to the wheels b/c it'd first have to go through an automatic tranny that already has a poor history of reliability.
