the supercharger for this car does absolutely nothing in my opinion for $4500. what is every1's opinion on a shot 75hp? what company makes something good? will the engine withstand that shot?

bklynpanman

does absolutely nothing? ha.. what are you smokin bro

lookinco

Nitrous for sure will be the best bang for your buck and our motor will handle a 75shot as long as you supply enough fuel. However it really depends how you run your car. If you only drag race at the strip, then sure nitrous will be okay. However on the street there are too much to worry about. First you would have to open the bottle, turn up the heater to warm up the nitrous, purges the line, etc etc. Unless you are prepared to race everytime when you drive on the street, chances are if someone started to race with you suddenly you woudln't have the time to open the bottle and engage your nitrous.
I like the Nitrous Express wet kit or direct port kit. They run about $1000 to $1500 depending on what options you get.

As for the comptech supercharger that I currently have, I believe $4500 for a well engineered and reliable kit is more then worth it. Of course there is also that beautiful supercharger whine. Many members here with SC and a few mods have dynoed over 300whp.

If you shop around, you can get the SC for under $4000. I got mine for $3750.

I think what he is actually trying to say is...........I cannot swallow paying for +1 HP@75$ each, can I get them for 25$ per? and the answer is .........yes kinda, its just a different kind of HP, not one that is on tap all the time!

mo's a-spec

will spraying on an automatic tranny bad for it? has any1 ever sprayed and happy with it?

pohljm

^^^^^^???????you mean like a skunk or a cat????

mo's a-spec

no. i mean will shooting nitrous on an automatic hurt my transmission inbetween gears while it shifts?

lookinco

Obviously with more power going through the transmission you would definitely put more stress to it, but most people seem to be fine with their trasmissions whether they are N/A, supercharged, or supercharged + nitrous.

Since you don't lift off the gas between shift in an automatic, I don't see how nitrous would hurt the transmission more as in the case of the supercharger. With a 75shot, they make about the same power.

BukvaMan

there is so many guys that have problems with that supercharger and having a hard time to get it to run the way it should so dont say its reliable and so on.....
for that much money it should be flawless

Atrain

LOL...if you add up all the bottle refills and the system, the costs will start to even out. Plus a supercharger is on tap all the time. I don't have to get out, turn the valve on the nitrous bottle and then race.

Bang for the buck is obviously nitrous, but they both have their pros and cons. You have to be very careful with nitrous oxide.

On the TL, the compression ratio is NOT supercharger friendly. With nitrous oxide, you'll do much better with a high compression ratio.

Better yet, use the nitrous to cool the supercharger air...now you're talking.

The only problem (if you want to call it that) is the surging. My s/c has been nothing but reliable.

lookinco

lol....what is the problem that people are having? Supercharger blowing up? Don't fit? Blowing up the engine? NO........ people who are having problem are the ones that have trouble modifying the stock fuel pressure regulator which is clearly shown on the manual.

Others who had problem with the fuel system such as bad injector or bad fuel pump is clearly not the problem of the supercharger.

Clearly, you haven't read any of the threads. Most of the faults were due to user error or vehicles with issues before installing the S/C. The only minor "problem" is the surging as dan....k mentioned.

chaperoah

what about the '07 TL S-Type? Can it take a super and make good use of it? Are there other mods that woud be essential and/or recommended to keep the car from blowing up or not making good use of the super? This is more of a curiousity question...

BustedJack

well said


first off, if you wanted serious performance and HP... then why the hell did you get a TL? Expect good gains but not too extreme when you buy the s/c... most of us here are old enough and mature enough to say "our S/C produces ENOUGH power on the street"
at 300hp to the wheel, it isn't what you called "does absolutely nothing"...

you want some serious HP, get yourself a mustang GT and go from there...........

BustedJack

WRONG. The supercharger itself is fine, the kit itself is fine. Those who have "had" problems either

1) defective FPR
2) bad installation


Those who had Ryan97812 install the s/c, never had any problems, myself included.

It's been 15,000 miles since the installation and it still runs like a champ.

meowCat

woah.. cool. I'm sure you're loving the performance of it. You got 6spd MT? With the supercharger can you get to around 5 sec in 0-60? Is this do-able for a TL 6spd MT with S/C?

ubnpast

No, I believe the engine pulls timing between shifts.

ubnpast

Its actually fun when you get a bottle opener, I had my bottle heater connected to my rear window defroster, so when I pushed the button up front it came on. It kinda sucks, I sold my zex kit, heater and opener for $410 on ebay, wish I would have kept it... You dont have to use the purge, I have found it to be a waste of n2o, anyway the air comes out of the lines within a split second when it kicks in.

pohljm

I dont understand this? what does this mean?

I also had mine installed at a local speed shop (Joe Demaree did it from SSC, well qualified NDRA driver) and have had NO problems whatsoever. Its all about the install I think...and the fuel pressure reg like you stated. From looking at the tool to modify the regulator (have in my hand right now)....I truely dont know how you could do it wrong...but I am sure there is a way!

MichaelBenz

iTrader: (2)

Its always best to purge INSIDE the car during off times...lol. (we use medical quality N2O around our parts) j/k....about purging inside....they do use med qual though...not that crap with the additive making it uninhalable...basically because most of the domestic guys spend a fortune on their cars...and wont put foreign substances into em after building that are not necessary....ie...the additive...I think its sulfer or something.

ubnpast

hehe, my shop uses the medical stuff too

ubnpast

I ment that timing is pulled between shifts, which means the engine slows down for the trans to shift .

bklynpanman

little hint.. someone on this forum blew up their 3g motor on nitrous... though it was out of stupidity..

MichaelBenz

iTrader: (2)

Oh...do tell do tell.....or lead w/ link? Was wondering about the application of N2O to the supercharged application and if it was a big deal or not.

bklynpanman

there is no thread.. check engine light came on.. bad knock sensor and he sprayed anyway.. not sure if it was a 50 or 75 shot.. and ka-boom...

BustedJack

wasn't Paul (againstallodds1) was it?

bklynpanman

ding ding ding

MichaelBenz

iTrader: (2)

WOW....so one would NOT recommend supercharger with nitrous...or was it just because he sprayed when the sensor was bad. Meth is the only other option I guess? Any known problems there yet?

BustedJack

wait a minute.........
the story he told me was he bought a mustang GT (remember he posted about getting a californian edition 2005 GT) and he was selling everything

S/C, crank pull, etc., and was leaving the TL for his mom?????

so that was a lie????????????? he actually blew up his motor? WTF

ubnpast

If were thinking about the one where the check engine light came on, he used a 100 shot...

Teddybear

uh... i think it would. ur adding a LOT mroe compression to the engine.. more than what a s/c would. mroe than what a turbo would too. engines arent made to handle nos period. it puts so much strss on the engine.. and all in one "shot" too.

n dont go on about how drag cars use nitrous n all that crap.. they replace their engines on a regular basis.. or at least engine parts... they do a complete overhaul every, 2 races is it?

RYAN97812

iTrader: (2)

Wrong there teddy bear, look at my avatar. I spray that motor all the time w/ a 250 shot and have almost 100 passes on it. And its a $13,000 motor. The motor before that was a STOCK 305 that i ran 175 shot for OVER 250 passes and 30k street miles without ever having to rebuild it. If youve never run nitrous speak to someone that has PROFESSIONALLY run it and dont go about misleading info for others.

ubnpast

This is how people get the wrong idea about n2o... The people that have never used it, get the unclear idea of what happens, and they spread the word that it is no good...

meowCat

Hey is adding a $4500 Comptek Supercharger on a 3rd gen TL make a lot of noise? Is it louder than stock? I like the way factory engine sound, nice and quiet. What does it sound like after you put this on??

MichaelBenz

iTrader: (2)

Just keep the stock comptech airbox on instead of going custom CAI like most of us do...and you will be quiet for the most part...except at WOT.

MichaelBenz

iTrader: (2)

I have used it...but it was on a chevy v8 that was built....is it ok to use like a 50-70 shot kit on this car though...without having the need to build the bottom end first? (of course...I was using a bit MORE on the V8....so maybe a 50-70 would be just fine on this motor) Ryan....any thoughts? So its all good? Just checking....I was looking at one of those nitrous express kits.

ubnpast

zex says a 20 shot for every cyl. is the max you should do, I think the tl would take a 75 w/o any problems, just as long as you use good gas, not regular or mid grade.

meowCat

Thanks for the reply. What's a WOT? is it like when you push the car to a full acceleration?


How much does it usually run for a certified place to have the S/C installed?
