Hey i want to put a supercharger on my 04 lariat with 60,000 miles on it is that a good idea i bought it brand new and have taken good care of it. Would it be a good or bad idea to put a supercharger on it with 60,000 miles or does it not mater if you have tooken care of the engine. I am going to get either a whipple or the roush ic kit from troyer. Witch one should i get. and either one i get what other parts should i get with it.

thanks

rob

 

60k Miles wont matter. What are your goals with this supercharger? If you eventually want built motor and over 8PSI, then I would go Whipple. If you just want to go 8PSI and stay around there then I would go ROUSH.

Whipple 2.3L Twin Screw
Pros:
less heat due to bigger blower
TwinScrew blower (blower makes compresses air internally, making less heat and more power)
with a Lightning conversion pulley set up it can do 20PSI without much effort
04 Kit is $3700 from what Ive heard

Cons:
Stock tune is fine but limited because of stock injectors
need atleast 39lb injectors to get full potential


Roush IC Kit 1.8L Roots Blower
Pros:
Troyer kit is 100% complete with aftermarket good tune.
Troyer kit can also be ported with pulley upgrade to make 400RWHP @ about 9PSI
Dual belt set up for easier boost adjustment (although over 12 on stock block is unsafe, 10 is about max you want to stay safe although FATHERFORD is an example where 12psi is fine with a tune)

Cons:
Roots blowers are inefficient at higher levels of boost and create alot of heat. (Roots blowers create boost by craming air into the intake and causing boost that way)
The ported kit from troyer (~9PSI kit) is expensive at $6-7000.

Finally last MAJOR Con of a ROUSH, most cars that are supercharged from the factory are roots style blowers like the roush, think Lightnings, Mustang Cobras. These guys often upgrade to a Whipple twinscrew blower for more power. Usually a stock Roots blown motor will be upgraded to a Twinscrew, Turbo, or sometimes even a Centri Type supercharger. Why buy what comes stock on many cars/trucks when you can buy what those guys upgrade to?


I went Whipple because currently I'm 10PSI with new injectors and tune and pulley. I plan to go built motor with 20PSI Whipple is the only choice then for me for positive displacement blowers offered on our trucks. Whipple with 10PSI will put out about 420-430RWHP while the ROUSH kit from troyer puts out about 9-9.5PSI and makes 400-420RWHP. Problem is the Whipple will hold power longer as a Roots blower will get heat soaked much quicker.

 

With 8PSI I ran a 14.5 with a 2.3 60 foot, if I had drag radials I would be high 13s. With 10PSI now I havent ran but should be 13.6-13.8 and with drag radials low 13s. I'm 2wd though.

 

My '04 Supercrew 4x4 had 62,000 miles on it when I installed the Roush non-IC'd and that was 21,000 miles ago. I chose the non-IC'd becuase it fit my needs and I was not building a race truck. I picked up an additional 100rwhp with the unit I chose. The most boost I have seen is 6# even in cooler temperatures.
Mike did the tuning on my truck also.
I did manage a 14.93 pass @ 90mph earlier this Spring the one time I took it to the track.

 

by the way the roush maxed out is 16lbs i beleive and you still need a built motor for that

 

Well the Roush Blower is a M112, a M112 is stock on 03-04 Cobra/Lighning (IIRC, both Roush and the C/L use a M112) and well yes you can run a M112 at 16PSI (I have seen Lightnings do that) they are very inefficient, which is why the same Lightnings Ive seen at that upgrade to a twinscrew and push past 16PSI.

A M112 at 16PSI and Twinscrew at 16PSI is a whole different game. Either way anything past 10PSI your pushing your luck, 12PSI you may need a motor on your way to work one day, and past 12psi you may see a rod leave your block externally at a high rate of speed.

 

Where can you get the whipple for 3700 lowest i found it was here http://dagostinoracing.com/index.php...ducts_id=12570

 

I believe Fatherford made a post about it some where, Personally I havent seen it, but Ive seen it posted on here many times that you can get them that cheap!

Word of advice, if you plan to run a boost gauge, do it during install, I did it after install and it was a PITA to reach behind the blower and do it.

 

The troyer roush setup is good, expensive, and limited.

Most of these guys are topped out with just about every mod and ported blower and doing 410-420rwhp.

If that is all you are looking for, go after it.

But as IRONS1N said, the Whipple has great potential, and if you look around deals come up. That $3700 was a Vendor ran special on SVT performance. Overall, I think anyone would be happier investing in the Whipple over the Roush.

As far as boost, I have done 12lbs now for over 3 years. I'm really considering get a 10% crank pulley and upping my boost to 13-14psi.

 

Do it. I've always wondered how much our engines can take on stock internals, you hear about the mustang guys running 14-15# on the 4.6 3v, so if they can do it why can't we.

FF, ATI makes a oversize damper in 6 or 8 rib for the mod motors and so does innovators west. Innovators has 2 sizes 10% over and 18% over.

Sorry for the hijack.

 

So would that be like 470-480 RWHP 500RWTQ ??

 

Yes sir.

 

go 14psi and hit that 11.99 mark

 

I have the roush running 8.5psi from Troyer, good little kit, expensive for the whole shabang but you might be able to score a deal depending on how much work you are having done. I agree that Whipple Twin-Screw is better but some of the statements on the Roush blower are inaccurate. The Roush is a M112 but it's upgraded from the stock ones found on L's and Termi's so it's much more capable than what people think. Also ITONS1N if you ran that on a 8psi Whipple, I ran 8.5psi with my truck about two weeks ago with everything including a 20lb load in the bed, I also have a tonneau cover and audio equipment in there for at least another 100lbs easy, spare tire and the mirrors were open too. Granted we may have other differences than the blowers but I rank just like you it sounds. Doesn't sound like the Whipple is doing much better than my Roush on initial glance, I'm telling you guys it's not the same old M112. I do want a Whipple TS as I said before, lol.

 

The catch with the roush is it's already starting to reach it's peak at those boost levels. The Whipple is just getting warmed up. You need atleast 10-12 for a whipple to really start waking up, and then go all the way up to 20psi. Just our trucks wont be able to take the power.
