That kit seems to be a good package but it's stupid expensive.

A generic Eaton blower would work but it would be lotsa fun to adapt it to the motor.

 

I don't understand how B&B can make an exhaust for the prowler and not the Xfire. The prowler had an even lower production than the crossfire is expected. Where is the logic? B&B makes incredible systems. If I had the dough I would have threw one on my SRT-4.

 

I am more than likely going to be doing a super charger or preferably twin Turbos on my X fire this winter. My wife bought hers on a monday and I kept talking about boosting it and she said no, so that Friday I got my own. I am spraying a 125 hp nitrous shot on it now for the summer, then when it is parked for the winter, I will tear into it and go boosted. I was planning on doing the plumbing and all now and running ~6-7 psi to get the bugs worked out, then next winter, I'll probably pull the motor and drop compression and such and crank the wick up then. I refuse to buy from many of the MB tuners as their prices are ridiculous, so I will be doing it mostly on my own.

I have a request in to Squires Turbo Systems (STS) regarding potential for one of their remote mount systems on the Xfire. I stepped out of a 300 hp SRT-4 and into the Xfire. I certainly want to go turbo and STS has received numerous SEMA best product awards. My HEMIsport Ram will get one of their systems in the near future. With the right package, water/alky injection, you can make some serious HP for far less (like half) of the current supercharger prices. If you are interested, start bugging STS to come out with a kit.

I thought about the SRT-6, but my dealer gave me too good of a price on a new 2004 white limited coupe. I figure I can do a lot with the almost $20K difference between what I paid and would have paid for the SRT-6.

STS is probably the most likely candidate to come out with something, they have already figured out how to make it work with the 5.7 HEMI ECU which is one of the worst to mess with. The HEMI kit is like $3,500 complete, the Xfire couldn't be that much more.

Are you referring to the rear mount kits? Never interested me for some reason. Great for bolt on and make more power applications, but never seen "big" numbers out of them. Pretty clever though.

Joe

 

I agree about your comments about the rear mounted systems. I think the concept is brilliant however, like Joe said, the numbers haven't really been all that impressive on the applications that I have seen so far.

 

You are correct, the rear mount system. I was off on the Ram price a bit, I guess with the final changes to the production kit, it is up to $4995. Still not bad though for what you get. No they don't make huge increases, but they are designed to live within the capabilities of the engine. The 5.7 Hemi makes the following numbers with the base kit:

Boost: 7 psi
Rear Wheel Horsepower: 417
%'d increase: 59%

Rear Wheel Torque: 460
%'d increase: 62%

I would be happy with the same percentages in a kit for the Xfire. I invested about $2K on my SRT-4 to go from 235hp to 300hp (w/race fuel), and I had to install a competition clutch also so that was another $750. My best time was a 12.7 @ 112 mph. Stock was like 14.3 @ 99 mph. If I can get to 330 hp or there a bouts with a remote mount turbo for even $5K, I would be very happy and still have $7K left over versus the Supercharger. Do me a favor, even if not interested, bug them anyway!

For your goals, that is obtainable with a rear mount kit, should they make one. You can even get creative and do it yourself. There is a nice "hole" under the rear of the car (where the Borlas resonator sits) where you could EASILY stuff one. I would go that route if I could bring myself to do a rear mount, but I would prefer to do twins off the manifolds (still have to get measurements to see what kind of room there is) easier to plumb and much more responsive than one larger turbo at the rear of the car.

Wouldn't hurt to stir some interest with them though.

Joe.

 

No doubt. I too have been kicking around the idea's of Twin Turbos, as well as a single large Turbo in the rear. You will get some explosive numbers if you run a Twin Turbo Set up. I have torn the front and rear of the car apart. I have gone through the whole shebang. As far as space goes, it is really tight up top in the engine bay. However if you remove about 50% of the plastic crap, that does virtually nothing, but get in the way. You have some pretty decent space for a large or a couple of med. sized intercoolers and plumbing. For the Turbo housings themselves, that's going to be a bit tricky, but I will say this much. My Intakes will sure make it a lot easier for me to get that forced air to that manifold.

Stir, Stir, Stir away my friends.

How about up front where the cats are right off the manifolds? Looked like you could fit a small turbo in place of them on each side. The car was jacked up from the rear, so I couldn't get a good look, but I am going to take a closer look at that area before I make any decisions. As for plumbing and such, I will have to take it as it comes, looks fairly easy actually compared to some other cars I have worked on. There is plenty of room for a front mount IC- especially if you make custom brackets to move the radiator back 1-2" towards the engine . I plan on coming up to the motor with a single 2 1/2"-3" pipe (depending on the turbos I use) from across the top of the drivers side of the bay (basically right over the coils) and use a silicone elbow to attach to the intake there. We'll see what happens.

Joe

 

Oh yeah- my biggest concern is ECU tuning and finding someone to do a custom tune. Upsolute can make some changes to their tune, but without them being with the car to tune it, I wouldn't trust a "custom tune". Renntech may be able to- but those guys get $1000 to reflash an ECU- lol, I guess the Mercedes name= foolishly spends money . I have done lots of tuning from ECU flashing on LT1 and LS1 F bodies to full standalones on various cars and to charge $1000 for a flash is absurd! The only thing they have above Upsolute in my book is they remove the speed limiter- Upsolute said they won't . Any ideas on who to turn to here?

 

You Can Fit 3" Across the top. Reason Why I know this is because, my intakes are 3" OD. You just have to make sure you have a descent bracket to hold the tubing, because you don't want to have one of those coils arch.
The other thing about placement. You have a lot of electrical running right behind the heat shielding sheets right there. From O2 sensors to tranny harness. These cars already run high temps, You may want to think about better insulation as well. I'll kick it around some more, and like you say. We'll see what happens.

don't doubt sts turbo's. the only reason dyno numbers don't look to crazy is because most people are running 5-8 psi. check this out and see if you have doubts...

right click, save as...

 

"unable to open site". Oh well. Anyway, 130mph in the 1/4 is fast- but far from big numbers . Again, these kits do not put out "big" numbers, but they do make more power than not running any turbo at all. I was running 130 mph traps with a stroker small block and small shot .

Joe

 

130 maybe not to great, but its an auto, but how does a 10.6 sound. its a 10.6 at 130

 

Shows he hooks well, I was running 10.9@130 on street tires- spinning the hell out of them lol. Not saying the car is slow, just not a wild turbo car. I know of a twin turbo early 70's Z28 putting over 1400 to the wheels. That is a nice number. Like I said, the STS kits are GREAT for the typical street guy looking for more power, but not a "serious" setup by a long shot. All depends on your goals. An STS kit on an xfire would make it an impressive, fun daily driver, but nothing wild- like I usually shoot for. Heck, my talon 5 years ago was 487 to the wheels on race fuel- and *that* was my daily driver for a while lol.
