supercharger acceleration

[mercurymarauder]

Just bought a Trilogy equipped Marauder...
it has dyno-ed at 430 hp but most of that
is in the high rpm band. Is there a way to
get supercharger boost at less than half throttle?

It seems as if my supercharger only kicks in after
second gear or past 3000 rpms. I really want
the car to take off from the stoplight (to beat
the import econoboxes) without going crazy and
losing control. Someone told me there was a
bypass valve? Another mentioned an Accu-Fab
throttle body? I must not be the only one that
wants a little pull into their seat with a blip of
the go pedal.

Oh yeah, the car has a PI 3000 torque converter,
4.30 gears, stainless steel works long tube headers,
racing fuel pump in the fuel tank, larger fuel filter,
magnaflow mufflers, and a few other goodies like a
driveshaft and trans level II mod. I would love to
spend a little more to get exactly what I seek.
It is a 2003A with 16,000 miles.

[usafsniper]

Not sure what the issue is, but mine is Trilogized and I had absolutely no issues with bottom end grunt. I routinely scare people with the neck snap they get from a cold start. I have the stock tranny, stock gears...only mods are flowmaster mufflers and a JLT.

[Marauder]

Most of the roots s/c guys complain about the opposite...less top end than a centrifugal s/c. The centrifugal tend to have a little more top end, roots have a little more bottom end.

With all those mods and 4.30 gears, you should launch like crazy so you may have another issue.

Maybe someone had it detuned?If your close to michigan you may want to have the man Lidio fix it for you.:up:

[teamrope]

When Carfixer and Tallboy did Bruteforce's install a couple of weeks ago they recommended that he swap the 3000 stall for a stock TC from an 04. The 3000 stall is hurting you off the line.

+1 on the stock converter.

That is the first time I have EVER heard that.

Would you happen to have a Dyno Graph Printout from when your car was Dyno'd?

Perhaps we MAY be able to figure this out.

That's probably it.

It's part of what Jerry Barnes was talking about years ago when he said people just needed the Supercharger, and didn't need to change plugs, stats, gears, etc.

Nah, its a roots vs centrifical thing. Like I said, we've been over this. In fact it was done before I came around. It was one of the desiding factors for me in my research into blower choices. I found the info by searching around.

Bulls**t. What line are you talking about. I just pulled a 1.668 60ft last Sunday with a 3.4 pulley.


That's probably it.

Again more bull and old information.




Call me on my cell phone (248)877-2792, I am out of the office a lot these days. That's the best way to get a hold of me.

My recommendation, go slowly. Install the S/C and see what the performance difference is. Determine if the installation is working properly and there are no problems. Do your dyno runs, check mileage and driveability.

Next, widened wheels and Nitto's. This helps avoid tire spinning into 2nd ear, then down shifting back into first once traction is achieved, which can hurt the transmission.

After driving the cars for 3-4 months, call Lidio and buy a 3.0 pulley and an upgraded tune. It's cheap, reliable and worth the money. Take the car back to the dyno, check the mileage and driveability again. If the upgrade meets with your approval you would have spent your money wisely, Grasshopper.

Next, talk to MikesMerc about his dyno data and get some of his advice. He has some very good data to share.

Next, Balance drive shaft.

Next, Metco control arms and wats linkage.

Next, Metco drive shaft loop.

Next, replace stock differential with EATON or Auburn unit.

Next, if the car starts to produce more then 500 RWHP, rebuild the bottom end of the motor and rebuild the transmission with drag pack pieces.

Next, start with a 100 shot of Nitrous.

Welcome to the 11's.

We are up to S/C # 160 or 161.

mercurymarauder:

The main operational difference between a Roots blower and a centrifugal is that the Roots makes most of its boost down low, but starts to run out at the top end. The centrifugal blower starts off a little lower, but builds boost as RPMs rise and eventually (generally) makes more boost than a Roots.

If you didn't install the unit yourself, you should contact the installer and tell them of your concerns. It's definitely not "a Trilogy thing".

No Teamrope is right. I was there. What's the big deal?
He's not talking about pulley sizes.

So am I right. and yes the information is old, very old, but shouldn't be before your time here. there is no big deal in that either.

Your quoted thread of Jerry's is newer, has nothing to do with what I posted.

I included the pulley size as a reference. I have a PI converter and a 2004 Stock converter. The PI is not slow off the line at all. I just happen to strongly disagree

[mercurymarauder]

Is this a characteristic of a Trilogy supercharger, or more
specifically the "bypass valve" which I never knew about?

The Marauder accelerates like a Grand Marquis until about
3000 rpms...or past second gear...no torque off the stoplight
at all...a lot of building up to rpms (makes me think maybe the
3000 PI torque converter is at fault?)

Does the Trilogy kit have a bypass that prevents boost at low rpm?
Can the bypass be bypassed" Is it there for a good reason?
What about the AccuFab Throttle Body kit? Some people here
have said that it gets you into the (torque) power band sooner.

Like I said all I want is to burn rubber at the stoplight when taking off.
My old big blocks did that in the 70s from Ford and GM.
What mods would you recommend?
How do you know if the transmission/torque converter are slipping
(cause the tires sure ain't until past 3000 rpms and not unless you
floor the accelerator). Is this the way it is SUPPOSED to be?

I would agree with "Marauder" - roots S/C's kick azz down low - My guess is it's a trans. issue.

I am not a "TROLL"...I own a 300A which I bought without a test drive based on Ford's reputation...and a cool poster of a Marauder smoking it's tires in front of a bunch of leather jacketed James Dean look-a-likes leaning on their old Marauders

I was just hoping sometime in the near future to have a hint of smoking rubber or muscle car testosterone...

My only problem is 0-30 acceleration...I wanted pull off the line...no spooling/reving/hard shifts...I hate getting beaten off the stoplight...

I am leaning larger displacement replacement motor (it is just against my better judgment to change the engine on a car with 8000 miles on it) or a roots supercharger...

Just for fun, do an internet search on the police interceptor Crown Victorias with V10 engines being installed...

What you need to do is stop asking us these questions and start asking whomever installed your Trilogy kit...or contact Trilogy directly. If you can't light up the tires from a dead stop, then there is something seriously wrong with your installation.

[OneBADLsE]

Just to chime in for a second...Even my 239 hp Marquis (albeit its not a locked rear, though still has 3.27s) can lite up the tires right through half of 2nd! I have to use a squeeze technique to get all of the power and none of the spin.

A BONE STOCK Marauder will not lite'em up off the line at all. I have driven 3 stock ones (all 03's), and i can say from experience that it will feel like a HPP Merc up until around 30.

Conclusion therefore is if you really did all of this work to your MM, you have a serious issue/s.

I was at Bruteforce's install party and was there to hear Carfixer and Tallboy tell him the 3000 stall was hurting him off the line and he would be better off with a stoker from an 04.

I don't have 1st hand experience with the Trillogy other than a test ride in Trillogy II with the Mrs at the wheel for a quick ride. My apologies for taking their words at face value.

Sorry to come on so heavy. Within the Marauder performance community there has been conversations about the benefits of stock vs. aftermarket converters. In the early days the PI was a must have item to achieve sub-13 second times. I read threads claiming performance gains of .5 tenths of a second. As the community progressed we are seeing a variety of engine/transmission combinations. I talked to Lidio about the subject and he prefers the 2004 MM converter. I yield to is wisdom, but disagree with his findings. You need all you can to push a 4400 pound car down the track. Lock up schedules is the key to getting the best out of an aftermarket converter. Engine tuning is one thing, but working the transmission is another.

[Blackened300a]
