    I won't argue with you on that, but it seems to work fine for the WRC cars...they all use water injection. And short of bolting up a radiator-sized intercooler, it's not gonna happen. The location of the heat-exchanger under the maggie is not optimal, not much one can do to keep it isolated from engine heat.

    And the GTO kit has an even smaller heat-exchanger under the maggie...one would probably be better off leaving the intercooler off and just install the W/I.

    Hey, if W/I can bring intake temps from 180* to under 100* in under a second, its not a bad thing. And it works in traffic, where no intercooler is going to do it's job well. Also, should one mix in meth or alky then octane is bumped-up considerably(a good thing that no intercooler is able to accomplish)...some Vette guys have added 50-75hp with proper tuning....again, not a bad thing.

    W/I = Chemical Intercooling


    And the V not being a street tuner car? I don't understand that...W/I is street-tuner??? That some sort of "Australian-Iron" closed-minded flame on W/I??? It's not a drag car either, hasn't stopped others from going down that strip...

    Not really sure what you mean by this?? Am I just wasting time and money on modding my LS6-driven luxo-cruiser?

    Get a decent tune and make sure you check your boost. With the 3.0" pulley I was running 4 lbs boost. With the 2.8" pulley, boost increased to 6 lbs.

    V's don't run for 30 minute segments or for an evening on the street like WRC/Street tuner cars do. They to spend most of the week running it's owner to work or picking up the kids. The owner is not going to spend time topping off the W/I or be keeping an eye on it.

    WRC probably uses W/I due to high load where the cooling system does not have time to recover. Something V will not see picking up groceries. My C32 AMG with twin-screw Lyschom blower that had a water cooler intercooler would not see over 150F or the DME(PCM) would start to pull timing on the road course. And it was tied to the main cooling system as an overflow when the main system heated up and expanded.

    Does the Predator tune start to pull timing at a certain IAT? What about Stealth's tune? A quick check would be to monitor it or after a spirited run to monitor return I/C hoses or the I/C itself.

    Heat soak was not a problem at 50F on the highway, not unless Seatle CTS-V system is not operating properly.

    But if a SRT-8 traps @ 109-110 and the V with Maggie @ 115 MPH, your not going to see a big difference in 50-90 MPH race.

    Torque spike on the dyno could see 30-50 ft-lbs.

    The SRT-8 is nothing more than a dumbed down AMG Benz. Having owned 3 AMG cars, I can tell you that the AMG Sppedshift tranny gives an unfair advantage from a roll. I have taken many faster cars on the highway when I could just nail it an instantly drop 1 or 2 gears and be gone. Now when running from a dead stop or on the track, things certainly turned out differently. My last 2 AMG cars could drop 1 or 2 gears faster than the latest generation of SMG equipped M3 which is a fast tranny.

    If you're going to race around 50 mph, you NEED to be in second gear, not third. Third gear from around 75-80 mph.

    Chris is going to nut his keyboard at this post. A maggied V no less.

    Good luck with second gear at 50 = zero traction -

    I figured that the time advantage I got from starting in 2nd gear would be negated by the time it takes me to shift from 2nd to 3rd.

    Re: Damn those SRT8's are quick!

    I guess some owner didn't care for their SRT8. When I went to drop the V off at the dealership this morning to get Clear Bra done, they had a SRT8 sitting on the "Pre-Owned" lot. I wonder if I can talk them into letting me take it for a test drive....

    Re: Damn those SRT8's are quick!

    When observing my car on the dyno, which has a LOT of runs of it, heat soak wasn't THAT much of an issue, so I'd probably pass on that idea.

    My first question is the same I ask of all Maggie owners--do you have the 3.0" pulley or the 2.8"? If the 3.0", that is a good place to start.

    If you have the 2.8" pulley, also make sure that you have the most recent tune from Magna. As others have stated, you will gain a substantial amount of rwhp/rwtq with a tune (probably in the neighborhood of 30-40 rwhp/tq). A V with a 2.8" pulley and a decent tune pretty much should have it's way with an SRT-8 without even trying hard. As a matter of fact, the driver would have to be woefully pathetic to lose that race.

    These cars are extremely close when both are stock (although I think the V is harder to drag race). As such, when either car is modded, it's going to pretty much defeat the other.

    And you guys suck--I drove my car for about 400 miles this weekend and couldn't find a SINGLE person driving a car that was "worthy," to say nothing about whether I could find someone to "play." I didn't think it was possible to run into 2,000 mini-vans/grocery-getters and not a single performance-based car, but I was woefully wrong...

    And if Chris wants to get his SRT-8 out here in CA, I'll run with him at pretty much any speed. And if he beats me, at any speed, I will buy the round of beers (then again, I don't drink, so it will be for everyone else...)

    And let's not spread "rumors" of how great maggie is. I love my maggie as much as the next guy, but, unless there is something else at play (i.e. water), there is pretty much no way that a V with a maggie (and no other substantial mods) is going to spin the tires to the extent that traction control comes on at 50+ mph in 3rd gear. I'm probably putting more rwhp/rwtq than most members on here and I couldn't come close to that...

    I definitely have the 2.8" pulley, but not sure about the 'updated' tune. As far as spinning the tires, I think we were saying we could spin them in the top of 2nd gear @ 50, not while rolling in 3rd.

    You gotta remember that cold F1's suck for traction. Here in MD, with cold roads I have no problem spinning the tires when I punch it in Third. Traction control immediately kicks in. Oh yeah, I have witnesses :-}

    Currently, here in MD it's 82 degrees, no spinning in third today !

    Re: Damn those SRT8's are quick!

    I was informed directly from Magna that they had a "new" tune for the 2.8" pulley. Now "new" was many months ago, so it might not be "new" anymore, but there was a definite upgrade to their "old" tune. Being that many Maggie units seem to still be sold with the 3.0" pulley, it wouldn't shock me if the "old" tune was still going out the door is why I make that statement.

    And I will try and spin my tires in 2nd at 50mph today at lunch. That isn't an easy thing to do either...

    EDIT--lol--okay, very cold weather would be one of those "exceptions" in my mind, but yeah, in that situation, spinning your tires in 3rd gear wouldn't be that hard. I could spin the crap out of them in 4th gear sometimes if the weather/wetness was right

    Re: Damn those SRT8's are quick!

    CIWS: What srt8 was there for sale? Charger? I can tell you that I drove the magnum 8 and it did not impress me! I can say that, a magnum, which may be a bit heavier, could not beat my car...ever with minimal things done! The computer is on it's way to Rick at Stealth V and we will see what it is like after that! I looked into the tuning quite a bit and came up with Rick as the most reputable tuner, from long distance at least, and after chatting with him a few times I would say he is the guy for our cars no matter where you are from! He has done it, been there and back and knows this motor and cars as good as anyone. The people who know the most are people who have been there, hands on for themselves! My guess is that I will be quite impressed with his tuning and I do all things to my car myself as nobody can do it like YOU!

    Anyway, I would like to know which car that is for sale there and they will DEFINITELY let you drive it! Give them a story about shifting all the time and rear etc. They will want you to drive more than you want to drive it!
