Comptech has a supercharger for the 3g TL's, is it worth the money to get it installed? Does anyone else make superchargers for the 3g TL's?

Yes. No.

Yes it is worth it. The sounds, the linear power, the reliability.

was the surging issue ever resolved ??

Hi speed

Yes, it was a knock sensor that needed to be wired around the Comptech box. Once I did that no more surging.

whats surging?

well it feels like the car is idling incorrectly like when you let off the gas the rpms bounce

surging was solved

22MGA

oh ok....

how was it resolved?

The Comptech computer box was giving bad signals from the knock sensor to the ECU making the engine think it was knocking what it wasn't. This pulling of timing to stay out of knock made the car surge alittle at some RPM.
Once the knock sensor was wired back to stock and not thru the Comptech box, the suging went away.

Interesting. So this was their way of pulling timing? While pretty redneckish, I'm not sure I would want to bypass that box even though the surging was annoying.

My thinking is Comptech felt they needed to alter the signals comming from the knock sensor to make the kit work properly when they were designing it. After testing Comptech found no need to alter knock signals and ended up not using that part of the computer box, but still using the directions that said to wire the knock sensor.

I think the computer box Comptech uses is the same or very close in all of their J32 supercharger kits. In past applications the signals comming from the knock sensor may have needed alteration, hence the input for and instructions to wire the knock thru the Comptech box.
On the 3rd gen or atleast mine the box was causing havoc with the knock signals and making the car buck and surge badly. Once you were over 3k it would stop, but there was something wrong.

I had my tech call Comptech and was told to wire the knock sensor back to stock and the problem would be fixed. I would rather have the knock sensor wired as it was stock instead of letting the box decide when it is knocking.

Since fixing the knock sensor wiring the surging is gone. As far as using the knock sensor to retard timing, once the ECU sees knock it retards too much, making this a retarded way of pulling timing.

I hate cars

The only thing I would be worried about is the best way to control knock is to prevent it in the first place. Once it starts, especially with the blower, it's nearly impossible to stop. It's better to be conservative with the timing than to have it blow up like so many of the supercharged cars are doing. However, if it was bucking and surging it sounds like something was wrong with the box.

I have the surging and like hispeed said, it's okay to wire it back to stock. I just havent had the patience to do so. Any useful instructions on how to rewire??

Tripnbeats

ill do it for u joe.
22 just make sure ur motor is up to par and ready to get boosted.....look up guys who do boosted work in ur area and ask them to run tests to make sure everything is ok.

I'm seriously thinking about getting the supercharger. I have about 65k on the odometer already. The engine runs fine and I love the car and plan on keeping it for a while. Is there anything I should be concerned about with me adding the supercharger at this stage of the game?

Also, any maintenance issues I need to worry about. I read something about having to replace belts...is this a common problem? I'm not much of a DIYer so I just don't want to get in over my head. Any suggestions/comments?

Tripnbeats

u think ur engine runs fine..... because it naturally aspirated...have it all tested and make sure its ok to boost it..... big diff in boost and no boost.

apnorm

iTrader: (3)

Thanks Tripn. What exactly do I get tested? What do I ask them to do?

Tripnbeats

make sure the valves are tightened or ar tight, your gaskets are good and not saturated, pistons have the correct compression ( and acura has a way to test for that with "special tools") but its a pretty basic test so i wouldnt worry, all the rockers are good and not stuck or loose, pulleys also need to be in good condition tensioners as well comptech gives you colder plugs i believe....coil packs may be needed as well, that depends on ur driving style, your O2 sensors should be fine, but at the same time you never know...have those checked as well as your cats. clean the motor out with seafoam a week prior to install to get rid of carbon build up and Id recommend getting the innovative motor mounts as well just as precaution....the mounts love breaking on this car.

listen to tripnbeats, Im lucky and got an entire new motor out of it... others may not be as lucky

Tripnbeats

Id do all this myself to make sure its ready...because i know how... but the mechanic whos installing the blower should do these tests for u and to do the tests its worth the money it'll save u a headache and a motor if its not up to par to be boosted.

Tripnbeats

lol yea man i break everything cuz its so much FUNN!!!!!

I plan on buying this from Josh and having it installed by him.

Josh - I'm assuming this is something you can do? BTW - I'm still waiting for that call back from yesterday!

Any issues with having to replace belts frequently or was that an issue only the the high boost pulley???

apnorm

iTrader: (3)

how much of a vibration will I feel with the mounts? I'm assuming go with the 60a?

Tripnbeats

the belt issue is from the pulleys not being stock i believe its throwing belts because of the UR underdrive....and yea josh is well aware of whats gotta be done....i wouldnt be worried if he was doing the install but id def bring it to his attention to do the tests. 60 or 75 the vibrations are ok nothing crazy mine shake the dash i think i have a blown mount lol. but again thats my fault as usual lol.

Tripnbeats

i think josh will say 75 for the s/c but i dont think its really needed, comptech developed the blower on the stock mounts so 60 should be fine.

Thanks for info Tripn!

Anyone know what size battery I would need to get with the supercharger? Any recommendations?

I generally recommend the 60A bushings for most TL customers unless someone does a lot of track time. The S/C kit doesn't require the 75A. The 60A is more than sufficient if you choose to do the engine mounts.

60a is fine, havent even installed mine, but hang with tripnbeats often.

You have some good advises here. May ask you about the fuel injectors. Do they need to be changed or the stocks are OK. My TL has only 25,500 mi and I bought it brand new. SO I know how the car has been driven all these miles.

7thGenV6

Josh,

How much should I prepare to spend for the installation?

Tripnbeats

comptech made all of their mods with stocks parts on the motor dso the injectors wouldnt do anything .... unless u had a way to program the computer and make them dump...then ud get waaaaaaaay more boost.

That makes sense. Now, with the S/C it is a must to get tranny cooler and later on the meth kit. But would the engine or transmission handle with just the S/C for about 1 year before installing the tranny cooler and later on meth kit.

For the supercharger? If you want an installation quote give us a call at 203-483-6100

I wouldn't do it without the meth. There's a lack of tuning and too many blown TLs. Sure, it might make it a year but the damage is being done every time you hit boost.

The trans will be ok without a cooler for a while. Run a good synthetic fluid. Your driving style affects temps more than anything. If you do short bursts or even long bursts but then give it plenty of time to cool off in between it will be ok. I still recommend the cooler though.

So the tranny would handle the boost but the engine itself would not.

I know you mention to get the meth kit that can hold 100% meth. Wich one was it? Not the snow performance 'cause I know it is 50/50.
