Ok, so I have a 2005 Supercrew FX4. I have a Roush intercooled supercharger, dynatech headers and high-flow cats, and a corsa exhaust.

I raced a Nissan Maxima this morning, and I figured I'd be able to beat him! He got a jump on me as we started out of a dual-lane left hand turn. Anyways, I started catching up to him in second at around 70. I just figured I'd be a bit more competitive. Granted, I don't have my Troyer tune yet, and i'm in Tucson, with crappy 91 octane gas, but I would like to hear what I should expect from my truck. Thanks!

 

I feel your pain.
The Maxima has a DOHC 3.5, and weighs maybe 3, 500 #. If you were catching up at 70 mph your truck was pulling real strong. Your new tune will help.

 

Sweet truck man!

Weight is killing you, plus, you prolly have 3.55 gears in it... maybe 3.73 if your lucky, and on stock tires.. it's pathetic... Shame on you ford!

ALso, you spent alot of money on exhaust.. getting air in and out is the key... but after you long tubes, you're still bottle necking the exhaust.. Maybe look into getting an "Xpipe" after the headers and running a true dual muffler setup. That'll free up a couple ponies.

The tune will help out because it will raide your shift points to help utilize that boost.

Good luck.

Sweet sleeper too.

 

I have a 3.73 limited slip. I really thought about 4.10s, but that will be something later down the road. I like that I can still get descent gas mileage on the highway. Any other thoughts on my situation from anyone would be appreciated!!!

 

Cars are fast these days. The Maxima is a high-14 sercond car (in the quarter)....about 6-seconds 0-60. The new Hyundai Azera is about the same. Sorta sux that a Hyundai can beat our trucks...but that's how things are these days. And the d@mned Toyota Avalon and Camry V6 are even faster.

You need a blown truck just to keep up with a lot of cars these days.

Your truck is running great. It's just that everything else has gotten so much faster.

 

He's right! My wife has one and it is wicked quick. You'll do better when you jump a Hemi.

 

Yeah my truck with the Roush is very quick for a truck but I dont expect it to take fast cars. ITS A HEAVY TRUCK not a light sedan or sports car.

 

I realize it's still a 6000# truck I'm dealing with, so I think I'm being realistic. It seems like there are a few people on here claiming to smoke some pretty quick cars with seemingly normal upgrades (i.e. no new cranks/pistons/cams). I guess I'm wondering if I should expect more, that's all.

How much difference would going from 3.73 to 4.10 make in acceleration? And, how much difference will the Troyer tune make? Wrong questions for the supercharger threads, I know.

 

4.10s will make a nice difference but not a hugely significant one.

What people "claim" they do versus what they actually do are often vastly different.

A 6,000-lb truck that runs with a 3,000-lb sedan is making twice the power. That's impressive in my book.

I seem to recall a thread where someone with a tune/intake/exhaust claimed he smoked Dodge STR-10s.

It's tough to "win" if the guy in the other lane doesn't know you're racing

 

You are right. The way some of these people on hear talk I expected a supercharger would allow me to take anything on the road

Well at least we know our trucks can take most trucks on the road including hemi and powerstroke powered trucks as well as many cars. Is my truck Roush S/C mustang fast no. Do I care No!


Good question re the Troyer tune. I assumed the sending the PCM to Roush would have given us the best tune avail. Will the Troyer tune do that much better for a Roush intercooled S/C truck?

 

Well put

 

The reality of the situation is that you learned a few valuable lessons.

1. Don't ever assume or figure that you can beat anybody in a race or sport without some basic information about your competition.
2. Know what your truck can and can't do
3. If you are going to street race someone, always move first, let them catch you.
4. Learn how to pick a race.
5. Last and most important, when and who not to race.

 

Someone has been watching too many Fast and Furious movies! It's a truck. The intent of my post was to see where other people stand with a similar configuration and get their opinions. Not to get into the Vin Diesel level of street racing knowledge. Thanks, though

 

I was just trying to help based on what you said in your post which focused mainly on your loss to the Maxima. Blame the gas, no tune whatever you want since the truck is not the problem.

 

It was stated you need boost to run with many of the cars these days. Sometimes that isn't enough. With my L ,even at 14psi I expect different outcomes in many of my races. Many times I see a post about "smokeing this or that" and assume my L is slow. I start thinking, "How is this guy with 100 less hp and a heavier truck smokeing the same cars I do?! Then I come to my senses and laugh because most of the cars getting "smoked" are only by a fender. Point being the overexageration of races.

I would expect your outcome. I'm assuming it was hot and since he got the jump, don't be discouraged. Blowers are affected much more in the heat/cold than N/A cars. Who had the inside turn lane? Find a Maxima, set up an even off idle race and you'll see a much different outcome with you out front.

Intercooler, tune and at least 10psi will be your best bet.
