WhiteOut Posted December 15, 2003 Report Share Posted December 15, 2003 Okay, I was just doing some looking around on the net and I ran across another W-Body page which says that RSM is now selling a supercharging kit for the LQ1, for a mere $5,100. Anyone else heard anything/have any experience with such kits? It sounds like its a tab bit on the pricey side, and the company has yet to contact me back to say exactly what the kit includes. They've got my attention though. Quote Link to comment Share on other sites More sharing options...
Redfox340 Posted December 15, 2003 Report Share Posted December 15, 2003 Well, first that RSM racing has an extremely poor record on customer communication / satisfaction. But, it's true that the supercharger kit for the DOHC [LQ1] is available. But since they know it's not in too high of demand, it is not posted on their website. Compared to other supercharger kits, yes, it's a tad higher (about $1000) than other vehicle applications. The way I found out (and posted it on W-Body Performance) was that a local enthusist from Ontario e-mailed me the details. I asked the guy who contacted me if he knew if there were any testing / specs / numbers to show... never got em'. - Erik Quote Link to comment Share on other sites More sharing options...
patgizz Posted December 15, 2003 Report Share Posted December 15, 2003 from what i heard you need to drop your car off for them to do the R&D (and pay full price) because they havent had anyone buy it yet and havent even really made the kit yet - unless they found a guinea pig with deep pockets who would actually let them touch his car.

94SLSDOHCUTT94 Posted December 16, 2003 Report Share Posted December 16, 2003 Vortech makes a supercharger for the LQ1 for $4100 and I dont even think it comes with an intercooler(I might be wrong though, dont really remember) Quote Link to comment Share on other sites More sharing options...
jeffcanada Posted December 16, 2003 Report Share Posted December 16, 2003 Who would be nuts enough to spend that kind of money on a w-body upgrade (don't get me wrong, I am a big w-body fan)? You can buy an engine for way less!!! Quite frankly, I wouldn't spend $5000 on a W car period, especially if that is $5K US (and hence sig. higher CA). For $5,000 you can probably find a nice trans am, or a very decent starter muscle car (ie. running well, but not restored). For ex. in the fall I saw a 70 Buick GS for $4500; not restored, but the paint wasn't bad, and it ran very well. Only reason I didn't buy it was that I didn't think Buick torque would fly too well in the Canadian winters, and I couldn't afford to have even a winter beater if I had bought it. Just my two cents [or since I'm a canuck, my 1.5 cents ] Quote Link to comment Share on other sites More sharing options...

And I fail to see a LQ1 supercharger kit on Vortech's website; where'd you hear that from? Who would be nuts enough to spend that kind of money on a w-body upgrade (don't get me wrong, I am a big w-body fan)? You can buy an engine for way less!!! Everyone has their own nitch to modify... Some people have the 3.1L Turbo... Others like the L67, and still seem others can't put away their DOHC... - Erik Quote Link to comment Share on other sites More sharing options...
94SLSDOHCUTT94 Posted December 16, 2003 Report Share Posted December 16, 2003 I cant remember where I saw it. I'll look around to see if I can find it, Im positive it's out there. Unless it was a dream, JK Quote Link to comment Share on other sites More sharing options...
topless94style Posted December 16, 2003 Report Share Posted December 16, 2003 I wont put away my DOHC until it dies. Then i will spend some money on a L67, but until then this powerhouse will dominate all ricers. Quote Link to comment Share on other sites More sharing options...
94SLSDOHCUTT94 Posted December 17, 2003 Report Share Posted December 17, 2003 Im pretty sure this was the page I was talking about seeing before. Turns out it was an RSM site but they claim the supercharger to be "Vortech". The application is on an alero but looks like it would work(space-wise) on a early to mid-90's 3.4 cutt, gp, lumina, or what have you. And it says something about 250hp@5200rpm's? I hope they're kidding, what do the new 3.4's like the one in the alero picture come with for hp, 160? 170? to only have 250 after the supercharger they're about worthless without one if you ask me. I wonder if it would work? anybody know for sure http://webhome.idirect.com/~rsm1/gasc.jpg http://webhome.idirect.com/~rsm1/alero.htm Quote Link to comment Share on other sites More sharing options...

RSM fabricated the rest of the parts. No, the 3400 motor RSM is talking about is the 3400 SFI pushrod engine. That's not the same as our 3.4L DOHC MPFI V6; and space for the LQ1 is an issue. What's pictured will work on the 2.8L / 3.1L MPFI and the 3100 / 3400 engines. Agreed though that the power increase would be sweet! My old Beretta would be a street king... kinda... :gone2far: - Erik Quote Link to comment Share on other sites More sharing options...
94SLSDOHCUTT94 Posted December 17, 2003 Report Share Posted December 17, 2003 so.....you're saying even if you can free up the space to install this thing on the LQ1, and assuming it is able to be installed, it wont work? It wouldn't supercharge the motor? Quote Link to comment Share on other sites More sharing options...

It wouldn't supercharge the motor? When you look at it like that, yes, it'll work out for you. But, you'll need more than just the supercharger. Intake piping, MEMCAL / ECM / sensors, oil lines (if applicable), fasteners / brackets... you see the issue? - Erik Quote Link to comment Share on other sites More sharing options...
94SLSDOHCUTT94 Posted December 17, 2003 Report Share Posted December 17, 2003 yeah......I do see the issue. I just found it hard to believe that it just "wouldn't work" and I assumed some custom work would have needed to be done anyway. Im not planning on buying it and trying to make it work, but if someone did, it would technically be a supercharged DOHC 3.4L right? and would it retreive the same % of increased HP as one that was made for the DOHC(assuming there is one in production somewhere) Quote Link to comment Share on other sites More sharing options...

However I don't know if you'll see the same power gains compared to the pushrod kit. Since research and development hasn't commenced from RSM, no one really knows what the LQ1 is capable of holding. And for that matter, no one outside of RSM probably doesn't know the S/C specs or exact details on fabrication. To my knowledge, RSM has been the only one (as of now) that has offered to create a S/C application for the LQ1. - Erik Quote Link to comment Share on other sites More sharing options...
jeffcanada Posted December 17, 2003 Report Share Posted December 17, 2003 Another thing to keep in mind too is that GM detuned the 3.4L DOHC from original design and testing so that you wouldn't be breaking trannies every few months. I know, there is some untapped performance that you can pull out of it, but I don't think your tranny would last very long above 250 hp. A 5-speed might take it, but surely not an auto.

As you can kinda see, they were (and maybe still are) wanting to monut the S/C on the passenger side of the motor. Relocate the coolant resivior and the push back the ECM to make way for the S/C. From there, the intake piping would weave itself down next to the bottom of the radiator and up to the throttle body. Still, many details haven't gotten off the drawing board yet to finish the project. - Erik Quote Link to comment Share on other sites More sharing options...
GrandPrix34 Posted December 17, 2003 Report Share Posted December 17, 2003 http://redfox340.tripod.com//sitebuildercontent/sitebuilderpictures/gtp_sc.jpg The deserted research project at RSM Racing:the entire 3.4 liter supercharger setup. It would inlcude upper intake manifold, reprogramed ECM/PCM, Mass Air Flow sensor, stainless steel piping / rubber gaskets and the Vortech supercharger (est. 9 - 15psi boost).
