Then why did you get the TSX? You're comparing apples to oranges.

Yes, the TSX Supercharger kit is going to be much better if we reflash the
ECU. But reflashing the Auto ECU's is not going to happen.
We do have a piggy-back box on are test cars ECU that should work on the
auto's but it will not make as much power. So we are planning on releasing
an Auto TSX Supercharger kit.

Damn, well i hope it dont take as long as this one is taking

 

sounds like they are kinda close to releasing the kit sometime soon

 

So... a piggy-back system on the auto and makes less HP than the reflash...

How much $ is this system and what HP/TQ gain to expect?

 

yea, too bad it was supposed to be released back in august.

 

remember Gran Turismo 4 was supposed to be middle of last year (i preordered it June of 2003). So since August isn't too bad. And supposedly the TSX is in the game.

Since they seem to have the cars ready, would they have a dyno for the cars yet? i think they would, wouldn't they?Also from what i read there is supposed to be a reflash when we get the kit? or are they saying that when a reflash is availiable it will have better gains?

 

yeah, I ordered GT4 back then too, but let's not compare the SC kit to GT4; keep in mind that they removed a great feature of GT4 just to get it out in the next few days...online suport.

I would much rather wait a little longer than have it be a poor kit.

 

GT4 isn't coming out until first quarter of 2005.

sorry for hijacking the thread

 

And it STILL won't have online play! [/HIJACK]

 

back on topic.... lol any new news from comptech?

 

i saw comptech ad on a magazine today, showing the RSX, TSX, and TL superchargers!

no pricing...

 

I haven't been following this thread recently.

What is the projected wheel hp for a 6MT with the CT S/C?

Do we know how much boost? It is a MP62 Eaton unit which is good for 10psi. I highly doubt we will see more than 4 psi from this kit off the shelf, but larger (or smaller) pulleys to bump the boost, new injectors, fuel pump, etc.

Also, is Hondata still planning the K-Pro for the TSX?

 

I actually think that 6 lbs of boost is going to be the "stock" setup for the Comptech Super Charger. This has been the case for most Jackson Racing units on Honda engines.

The Comptech TSX featured on Temple of Vtec (pictures there) from 2004 SEMA showed specs of 240 WHP, which means a 55-60 HP increase to the wheels (180-185 WHP is stock). This puts the TSX very close to a stock TL in terms of power. That's a 30% increase in power at low boost. Very nice, indeed, and just what would make the TSX what it should be right out of the Acura box. Crank HP would then be approximately 260.

I realize that this is a repost, from this very thread in fact, but somehow writing about this topic makes me excited, and I don't mind repeating myself at all However, do a search and you'd easily see this discussion a few pages earlier on the thread.

By the way, if the Comptech offers a stage 1 upgrade to 8lbs of boost for 15-20% more power, that would equate to about 300 WHP....time to get serious with clutches and injectors

While it may seem a bit over the top, it is actually fairly conservative when looking at the Jackson Racing line of superchargers. I am certain that the Comptech unit matches up well to the performace of those.

Also....Imagine the torque!! If the JR Superchargers are indeed a good measure to go by, then you also will receive about 28% more torque at 6lbs of boost, making WTQ approximately 199. Go to the 8lb pulley for 15-20% more and you get about 228 ft/lbs. Yummy.....that's 213 crank torque at 6lbs, and 245 crank torque at 8lbs! and all at conservative calculations!

 

YAY! that would be great..

 

Your calculations are pretty far off IMO.

A TSX that makes 240whp is not going to make 260 crank horsepower. Try more like 285.

Also, 6psi is a pretty hefty amount for an already 10.5:1 compression. I wouldn't (and I currently don't) go more than 7psi without intercooling. Comptech usually starts boost numbers quite low on their roots style S/C's. (think 4psi)

What engine are you refering to with your JR S/C numbers? I'm assuming the K20 from the RSX-S. 6psi on the RSX-S will make more power than 6psi on the TSX. The JR S/C kits also only come with a 5psi pulley.

 

The RSX kit makes roughly 235whp with 5psi and I/H/E. The RSX has a 11.0:1 CR.

The TSX with 5psi should make rougly 220-225whp with 5psi and I/H/E. The TSX has a 10.5:1 CR.

 

I use mostly percentage calculations when I look at what a supercharger will do. I based my calculations off of what I read and saw at vtec.net. Comptech's TSX unit is claimed to be at 240 WHP by Comptech themselves at SEMA. So I used the % difference. 240-185=55 HP. 55/185=29.73%. 0.2973*200=59.46. 59.46+200=259.46 Crank HP.

Alternatively, you can take the claimed WHP and multiply it by the assumed driveline losses of the mean of 12 and 15% (for a manual transmission) and add about 2 to 4% for supercharger parasitic loss. So I estimate 13.5%+3%=16.5%. 0.165*240=39.6. 39.6+240=279.6 Crank HP.

You're right that the second method is probably more sound than the first, so in reality I am going to have to agree with you, the crank HP is more like 280 rather than 260.

My Supercharger experience does come admittedly from my last car, a 1991 CRX Si with the stock D16a6 SOHC Non-VTEC engine. It was a Jackson Racing unit, and it ran at 6lbs of boost, later at 8 with the stage 1 upgrade. I simply assumed that JRSC's all ran at that boost level. With my engine I saw 45% gains in horsepower over stock (with I/H/E) with the base setup, and 20% on top of that with the stage 1 upgrade. I also had the Zdyne Super ECU and their injectors, and had my car running at 215 WHP. Quite an amazing little car to drive. And a very reliable 215 WHP I might add!

But that sucks I hate talking about my old car, I sold it to save for a TSX, and I will miss it every single day until I am in my new ABP 6MT w/Navi....

 

240 WHP... Hmmm I wouldn't want to complain about that one. I rememebr the RSX with the Kpro was producing 212.5 at wheels? And it wasn't even properly tuned. Put those two together and I'm sure 250 WHP is more possible. And that I like

 

The RSX makes 230-235 whp with the Comptech S/C. I wouldn't expect much more horsepower than what the RSX makes. It is basically the same kit. There might be a little more torque, but top-end should be very close.

 

my girl has a rsx-s supercharged with jackson racing race kit 7psi 550 injectors hondata and ik24 plugs and she is pushing down 280whp 330 crank hp .I personally think i will go with the sc for easy install and reliability and no tapping of the oil line.I know turbo has more power to be made but id rather mine be a lil slower and still run then be faster and blown up in a month , david

 

What I would like to know is what kind of 0-60 and quarter mile times we will be looking at with these speculated gains. Anyone have any calculation for that based on these numbers?

 

since the tl weighs about (i believe 200 pounds diff) the same and the tl has about 235whp so i think that looking at what the tl runs is somewhat in the same catagory as a 240whp comptech tsx....

but i could and usually am wrong

 

A 240whp TSX will run close to 13.8 @ 102 MPH based upon its weight, gearing, and horsepower. As long as there isn't much wheelspin off the launch. Stock tires + 240whp =

0-60 with high hp cars is so dependant on a good driver it isn't even a meaningful statistic. Quarter mile is a much better way to calculate an increase in performance.

For instance:

On my CL-S, I dropped roughly 1 second off my 0-60 time with my modifications. I don't know the exact time, but based upon my quarter mile experience, it is roughly 1 full second.

But, in the quarter mile, I've dropped 2 full seconds and increased my MPH by 16. A gain of 16 mph is HUGE and really shows the increase in horsepower.

 

The stock MT TL 0 to 60 is 5.2 seconds, and it outweighs the TSX by 200 lbs. The TSX with CT Supercharger just might smoke a stock Z and definitely a G35. I cannnot wait to break out my sleeper TSX on those f#%@ing Mustangs, Camaros, and most of all Bimmers.

 

Muhahahaha, that would be sweet.. but u guys really think a comptech tsx could hold its own against sthose v8 mustangs and camaros?

 

Maybe a bone stock one, but with a few basic bolt-ons, prepare to get eaten alive.

 

no way.

 

It's actually 5.8 Seconds. That half second can make a world of difference for some people.

 

I'll find out where I saw this, but can anyone back this up? That thing smokes, but it does not handle nearly as well as the TSX. Imagine your car with an extra 200 lbs, but an extra 60 to 80 horses. It will make a big difference. With the right driver and tires, a bone stock TSX under the right conditions can hit mid to high sixes. Sauceman, where are you?

 

I agree, and thank you for the clarification. Is that the official Acura time? I have seen some pretty bad numbers for the TSX in different magazines and websites, and numbers that vary quite a bit. I think the TL time was on the Car and Driver website or Consumer reports. It was an online comparison somewhere, but the number sticks in my head. Whoever got that time obviously knew how to drive that car. Needless to say, I think it is safe to say we all can't wait to find out firsthand just how much of a difference the CT SC is going to make. I think the TSX will be just about perfect after that.

 

Man - if the price is right on this thing ... I just might jump on it. I am not big in to mods, but if this thing can make my TSX a sub-6 sec 0-60 car that's the real deal Time to starting saving my coins

 

You're right on times varying from source to source, but I thought those were usually between AT and MT and usually 1/4mile times. I got that from C&D or Edmunds... I forget.

Just don't race a GT or SS. Other than old school muscle I'm not really down on domestics. Though our Dodge Grand Caravan has 275,000 some miles, it's broken down continuously since 20k miles.

 

if i were to throw this supercharger on my TSX post 100K warranty period, would an engine with that many miles on it be capable of taking the additional stress of SC?

 

I would think you'll be fine. Honda motors last FOREVER. The only real wear on the engine with a S/C (as long as you have proper fuel delivery) is the valves and the rest of the top half of the engine. The amount of boost is fairly low. I installed the supercharger on my CL-S after 78k miles. 5k miles later zero problems to date.

 

how much weight will the super charger add?

 

Maybe 50 pounds. Not enough to make a difference, especially given the horsepower it will add.

 

So what do you guys think ... does this thing get the TSX around 6 sec in 0-60 type speed? I just have no idea what 240whp would be like in the TSX. Is this assuming other mods like I/H/E as well?
