Official V6 HP?

[fierodeletre]

Well I know some guys were disputing D3's claims, and I'm as skeptical s they are, but I did read in I think Road & Track today that had a head-to-head of a bunch of higher-end cars that had been lightly tuned. D3's CTS was rated at 340 BHP and 292 ft/lbs of torque after what the article described as a "custom intake system with a heat sheild" and a corsa exhaust, (no doubt fully encompassing the exhaust from headers to tailpipes). Despite this, they rated the car at 6.1 0-60 and 14.5 1/4 mile. Maybe this was an AWD model? They had also modified the braking capabilities of the car, so maybe it was significantly heavier as well. I also would expect that a tuning of the ECM had been done. But that's still pretty cool to squeeze those extra horses and pound feet in a natty-aspy 6 of just barely more than three and a half liters. I imagine that if you're driving an LS or LT with the 18s, you'd be easily bumping the times to sub 6-second and low 14s with these or similar mods. Now, if only GM would announce pricing on the GMPP intake, not to mention its stats as to flow, etc. Also, I am curious what the exhaust system they plan on selling includes and its stats. A 340 HP LT camaro with full warranty is fine by me.

300 - 304 hp is great either way. I just wish the torque was pumped up a bit more. It would be great to have a V6 feel and perform very close to my LT1 V8.

It should, actually...maybe not outright beat it, but "very close" as you said.



EDIT: I don't want to start a war, again...so I'll just say "V8>V6, etc, etc and all that jazz..."

to elaborate on this more from an LT1 owner, it will feel about the same when moving, but i dont think the lower torque of the v-6 will give you the same take off feeling as the LT1 does. but it could very well feel the same depending on the torque curve of the motor. thats one beneficial thing about the LT1, it makes torque at a low rpm and the stock torque converter engages at a low rpm as well so it plants you in your seat. I imagine that the V-6 will still do the same, but will have to be at a higher rpm to get the same torque

I'm curious, now that you mention that....

Have you ever had your car on a dyno? I'd be interested to see a power/torque map for the LT1.

This car is geared much higher off the line then the 4th gen cars. A4's 1st is 3.06 vs A6's 4.07 or manuals 4.48. Rear end gears were as low as 2.73 up to 3.23(I don't remember if 3.42s came on V8s). 5th gen gets 3.27 unless you get a manual SS. People quickly forget what kind of huge mods gears and converter were on 4th gens. This car pretty much comes standard with huge gears off the line due to the steep 1st.

why not just get a 8 banga yo

not since ive owned it, I was going to get it dyno'd but the trans took a isht on me 2 days before the dyno day we were having down here.

ive got one from when I first got the car from the previous owner tho, peak numbers were 423tq/411hp

but thats just a "little bit" of mods too...lol


as for an LT1 dyno, its about like this.... at about 1800-2200rpms, it kicks in and is relatively flat across the band.

another good point. (and there were 3.42's on some of the manual 4th gens)
but something to keep in mind is that the rear ratio is now partially offset by the steeper 1st gear.

that LLT is one bad lil mofo. id like to have one to play with.... switch to ethanol, slap a couple turbos on that bistach and crank it up.

tho, im with you. I was debating a 6-banger, but after Dragon first posted his pics of Indy, I couldnt let myself settle for anything but an SS.

Yeah that would be great to know, as I don't really know much about engine modding. How much hp would it take to make up for the lower torque of the 6?

not much really, the thing to keep in mind is not peak numbers. trailered dyno queens can keep their peak numbers, id rather have useable power under the curve.

what i mean by that, is that if it makes... say 275lb-ft at peak, but the torque curve is relativly flat at say 250lb-ft from 2500rpm up to say 6300rpm where the peak power is, then you are better off as it has more power under the curve to use at lower rpms instead of having to rev the crap out of the motor and only using the upper 2-3k rpm to move the car.

[kanys]

^ah ok thanks CamaroSpike, so the max torque listed is just the torque at max rpm, and it varies as the rpm varies? And so for just regular driving it would be best to look at which car has the highest area under the torque/rpm curve?

Another thing to keep in mind is that you can't increase horsepower without increasing torque, because torque is used to measure horsepower.
