hMMmmm................ interesting. I think I want one.... NOW. LOL

Kenny,

I don't know if this has already been asked. With all the additional horsepower and torque, do you feel any torque steer under hard acceleraton?

bigwilliestyle

Also, (I think there's another thread on it... maybe),

are there any other negative effects on your car as a whole?

Maybe long-term durability or faster wear?

Tsx536

First off, let me say sorry for the super long post. It's a slow day at work

Torque steer hasn't been a problem. I haven't noticed any but I'll try to keep on testing this out. I think the amount of power that was added is right along the lines of what can be added to a FWD without ruining the driveability. I will try to do more hard acceleration just to test this out for you Jlukja

I'm very happy with the Supercharger. In the last few days I have been driving more normally and not necessarily trying to push the car hard every chance that I have gotten. The car just drives really smooth and I feel like I have plenty of power on tap whenever I need. The acceleration is a lot more effortless and smooth. Whenever I want to pick up some speed, I don't need to push the engine as hard as I use to. I have a lot of good power in the midrange and don't have to rev the engine as high to get moving anymore. This has helped out a lot around town and on the freeway.

As far as negatives, the only one I can think of is that it is far too easy to go fast now. When I'm going 80 mph on the freeway, I'm only on the throttle about 5%-10% and it feels like the engine is barely doing any work. If I push it to about 50% throttle, I hit 100-100 mph with very little effort. This is a bad thing because I've noticed that I am passing people at 100 mph more frequently now. I always pass safely and make sure there are not cars in the way, but I would still get a huge ticket if a cop were to see me.

I've also been doing some testing with the difference in gas mileage. As of right now, it seems that there is very little difference in my mpg if I drive normally. If I'm at WOT and up in the high RPMs a lot, it definitely uses more gas though. I will let you guys know my results after I've had time to do more comparisions.

I'm not sure about the long term effects, but I've heard that a Supercharged Car can still be very reliable if you don't abuse the engine, make sure to change the engine oil reguarly, and change the oil on the SC blower every 50,000 miles. Other than that there is not really any additional maintenance. Keep in mind that I am running a 5 psi boost which is considered modest.

Also keep in mind that I am only boosting a small percentage of the time. I took the following info from the CTSC FAQ on ClubRSX. Those guys have been running the CTSC on their cars for awhile now and have a kit that is similar to the TSX kit.
Will there be additional stress on my car?
Any performance mod adds stress. However, the CTSC system has a bypass valve that cuts out the compressor when no boost is required, which means that 95-98% of the time you're not boosting and not adding stress to the engine. The compressor uses less than 1/3 of 1 hp when cruising at 60 mph.

How does this bypass valve work?
It is a butterfly valve like the one in the throttle body (see picture). The default is closed. When vacuum is high (idle-cruising) an actuator opens the bypass valve so that intake air bypasses the compressor. When accelerating, vacuum decreases and the bypass valve instantly closes. Intake air now goes through the compressor, building boost.

Great post. Thanks for the update d00d.

WoW, i want to see your car drag with another car like a new TL or rsx type S. MAybe a G35. PLEASE!!!

cArKc

will it keep up with the TL's, rsx-s, G35's, and even the WRX??

Any vids yet?

Hi Bro,

I am kind of interested in this supercharger, but I am not local. I live in Singapore currently driving a CL7 2.0 Auto with a little mod by putting a unichip 32bit and a Apex RSM limited edition. My horespower on wheel now is only 139 before that is only 129. If I am not wrong, supercharger is not available in my country so not too sure how to go about it or what what things I need to do before installing supercharger? Hope to hear from you real soon.

Cheers

Aloylee

TL and RSX-S, maybe, but there's no way in hell it will match the power/weight of a G35 or WRX. It is still a 3200 pound car with a 200bhp 4 cylinder engine.

acuratsxms

do you think its possible to race a stock G35 automatic with a SUpercharged TSX auto with some extras like headers Etc? AND have a good race

PixelHarmony

So the vtec being dropped to 3k doesn't affect the fuel consumption that much?

I'd love to know how easy it would be to swap the pulley and up the boost.

I'm working on it. I need to borrow a camera from someone.

Tsx536

Since you have 2.0 liter engine, I don't think that this is the kit you are looking for. The TSX here in the US is a 2.4 Liter engine. You might want to do some research and look at the Supercharger kit for the RSX. http://forums.clubrsx.com/forumdisplay.php?f=139. Let me know if you have anymore questions. Good luck!

Tsx536

I have no idea man. I'm not sure how I find something like this out. I'm mostly driving on the freeway and whenever I see G35s, they seem to be driven by old guys If I ever have an encounter with one, I'll be sure to post though.

Tsx536

Well it's a Vtec Window from 3k-5k. So you're not necessarily in Vtec above 3k. You'll only be in vtec if you're giving it a lot of throttle. Anytime you're above 5k you're definitely in Vtec though.

It wouldn't be too hard to swap the pulley. It would take about 1 hour for someone who is experienced. This would up the boost, but without a new reflash you're car will not be tuned to properly and safely make use of the extra boost. You would also need new fuel injectors that will deliver more fuel to the engine. Comptech will most likely release a Stage 2 SC kit at some point which will include a different pulley (smaller for more boost), high flow injectors, and a ECU reflash with new turning.

rmpage

Do we know what duty cycle the stock injectors are at during WOT right now? Normally I think they're already around 70%.

Also, this is becoming an appealing option to me considering that, as an AT owner, I may not be able to use a Kpro when it becomes available for the 6MT models.

Tsx536

Yeah I'm not sure what duty the stock injectors are doing at WOT. That would be a good question to ask Doug at Hondata though. I'm sure that he would know. I do know that the stock injectors start to max out at 7200-7300 RPMs. That's what the rev limit for the SC is set around there.

I think the SC is a great mod. If you ended up getting it and then K-Pro is released, I think Hondata would give you a reduced price since your already an owner of the reflash. I believe that in the past Hondata has given a discounted rate to people going from one of their reflashes to K-Pro.

Take a look at this link for the RSX. They charge RSX reflash owners $500 to upgrade to K-Pro instead of charging the full $995.

Huh, cool. I'll probably figure out what I want to do in a month or two. My shop said they'd be able to put together a turbo system for like $2500 or so, but I've always preferred supercharging with autos, especially now that DBW makes it that much more difficult to modulate boost.

It's only money.

Tsx536

Here are a couple of short video clips. Keep in mind that I have an 5AT. With an auto I have one less gear than a 6MT. I stay in each gear longer so my tach doesn't move as fast as a 6MT's does. I reach a higher top speed in each gear than a 6MT does though.

Here's a quick comparison of the longer gearing:
At the top of 1st I'm at 45 mph, a 6MT is at about 30-35 mph
At the top of 2nd I'm at 75 mph, a 6MT is at about 55-60 mph
At the top of 3rd I'm at 105 mph a 6MT is at about 80-85 mph

In these videos I'm only pushing it hard in 1st and 2nd gear. By the time I hit 3rd I'm going pretty fast, so I let up on the throttle. These videos were done on some country backroads to make sure no other cars would be around. The sound level is kind of low, so you should turn your sound up. My car is pretty quiet though.
My mods are Comptech SC, Icebox, DC Header, OEM cat, OEM Exhaust.
Enjoy!

I'm actually holding the steering wheel and camera in one hand and shifting with the other. So that made it a little tough. Hopefully I can get 2nd gear to move even faster with a little practice in finding where the sweet spot on the throttle is. What I've found is going full WOT doesn't necessarily make me accelerate the fastest. Hopefully changing my CAT will help out with that.

That's some tall gears and your car is so quiet! Are you running stock exhaust?

HONgDA

iTrader: (1)

so what's the top speed you reached filming this video?

jiggaman

if only the TSX came like that from the factory...

joerockt

Nice vids...Those are some pretty quick trips to 90

ryanhook

Ummm... yeah... I want one now. Wow.

Tsx536

Yep stock exhaust.
My ride is pretty quiet actually. Silent but deadly
I'm going to probably put on the Random Tech Cat next.

Tsx536

I shut it down right after I turn the camera off. So whatever speed you see in the video is the top speed.
Probably like 105-110 mph. And that's in 3rd gear too

Tsx536

I just pee'd in my pants...AMAZING!

ACCURATEin

I almost wrecked the first time i tried to film the gauge cluster and hold the steering wheel. So i came up with a camera mount that hangs down from the visor and it worked pretty well.

I just got done comparing your video clip to the one i made. Both cars seem to get up to 100 fairly quick.

Nice job man!

GSGOMEZ

Damn, that's awesome!!!!!

yuhoo22

i just creamed my pants.....too bad I can't justify the mod

savage

damn that is sooo sick... more temptation...

Tsx536

Yeah it's pretty dangeous trying to hold the camera and steering wheel at the same while shifting. I don't think I should do that anymore. I thought about a mount off my visor too. How did you do it?

Do you have a link to your videos? I'd like to see yours.

Tsx536

Found a couple of kind of cool pics I took recently.

observer

I don't know how exactly to read the dyno graphs, but are you guys saying that my 5AT really doesn't have 200hp (and not even close) like Acura advertised?

This graph is also bothering me immensely. I feel cheated.

observer

Okay, I do understand that there are different ways to measure horsepower. But even so, if you compare the 5AT and 6MT dynos (presumably measured the same way), there's still a ~25hp difference between the two.
