Any V6 with 300whp?

[KMPrenger]

If the CEL could be avoided without a tune, the biggest bang for the buck would be a set of BBK long tube headers in my opinion....but thats not really as viable of an option for most folks so after that I'd say a CAI is the next best thing.

But in reality, if you can only do one mod on this car, it would be exhaust all the way for me. Would rather have the great sound than just adding the power that a CAI gives.

I'm sure the "Dynojet Correction" shown on Abygale's post in this V6 Dyno thread is optimistic, but it's definitely showing impressive gains even on the uncorrected dyno run. I'm new to all of this; but, it sounds like you could get close.

------------------------------------------------

On the subject of headers, I've been reading some good things about the Doug Thorley shorty headers for the V6. A California member posted some impressive gains using them, they don't appear to create a CEL condition, and they're pending CARB approval. I just wish I noticed them before the introductory price elapsed ($325 woulda been sick).

I want to combine my Injen Intake (which gives me an awesome interior sound during acceleration, btw) with some Doug Thorley shorties and a nice exhaust. It won't get me to 300; but, it'll be a fun ride. That's what we're all here for, right?

Looking at the exhaust on the V6 cars, I personally can't see there being much gains to be had from it. Actually to be honest it's the best looking factory V6 exhaust system I've ever seen.

Longtubes may fetch a little bit more but I can't see the gains being very high. Then again I didn't expect to see the gains we saw from the CAI's but we did.

Yeah..mufflers alone don't do much. But LT's (with high flow cats) seem to do great work. While the sound they tend to produce may be a bit much for some, they typically seem to dyno an extra 15 give or take a few HP at peak, while getting 20 to 25 HP/TQ around the 5,000 to 5,400 RPM range.

300 rwhp N/A is possible, one will have to go further then standard bolt ons. Long tube headers, hiflow cats, catback/axleback exhaust, intake and tune will get you close. Again, I've got those things, I'm floating around 280rwhp.

To finish it off, add an underdrive pulley (if belt length was ever figured out), and then do what bmwdon has done, port and polish a set of heads, intake and throttle body. I'll wager over 300rwhp will be realized.

The downside? That ~50rwhp is going to cost you close to $5k. It's easily been about $100 per hp. And that's an auto car, I think it'll be faster to reach in a manual one!

Or, do what ROD1 has done. Grab the basics, toss in a 100shot, and run mid 12's!! That's still freaking awesome, and should have made you COTW.

Really? All of that and you're only around 280? Do you live at a really high altitude or something? Stock is around 250rwhp I think. I would imagine that you should have more than a +30rwhp gain with all of that.

About 700ft+, southern Illinois.

Yeah, location is going to play a part, and my car didn't dyno 250 baseline, lol. Low 240s. That's why a manual car, with my same mods, in my location, would probably be at or near 300. They typically dyno in the 260s stock.

A 30 HP bump is HUGE on 250. Why do you all think that some bolt ons are going to give you crazy HP gains. These engines are not that inefficient to begin with. Adding 30whp to a V6 and 45whp to a V8 is damn good for bolt ons and a tune.

Listen to the people who know what they are talking about. adding 50 HP with bolt ons is NOT going to happen on a V6. You barely get that on a V8 with all the bolt ons!


As said over and over again. You can get close. Start with the M6, do all the bolts on and a pulley and get as close as you can. I am betting you WILL NOT get 300 without cracking the engine open and if you have to go that far and spend that much... Why not just start with the V8... you'd be well over 300 right out of the gate.

Because some of us like a challenge? Cheaper insurance, better gas mileage?

I still think a M6 car, with my mods, will be at or near 300rwhp, they typically dyno 20hp more then autos. And, with what bmwdon is doing, will be well over that. Again, that's all without opening up the engine, just adding some port and polishing to what's already there.

All this arguing is making me think a CAI isn't really worth as much as I thought it was in the end. I'd rather just get LT headers and a cat back exhaust to gain power, improve sprung weight and get the sound better. If a CAI is only going to add 5 HP with those other mods, it doesn't seem to be a priority.

We might be able to hit the 290s, but without some work on the inside we wont hit 300.

For anyone interested. I'm more interested in the tuner.

Good morning Tony,

Thanks for your inquiry!

Our engineers are working on getting a 2011, ZL327 developed and it will have 327HP. Cannot say for sure exactly when it will become available but know it will be soon. Keep checking back!

Have a good day,

I will give you the challenge... a challenge is usually fun but in the end leaves you wanting more or something else. This was a perfect response. Now the other two... well...

The insurance is dependant on lots of things besides 2 cylinders... age, sex, credit score, maritial status, income, location... etc. None of which has anything to do with the car. I am 33, married, live in BFE Ohio, have really good credit, a good steady income and I bet my insurance is lower on my SS than a lot of people with a V6...

The gas mileage... come on, save that for Al Gore. If you REALLY cared about gas mileage, you'd drive a Prius, and you would not care about adding HP. Don't try to kid yourself into thinking you got a V6 to reduce the amount of fuel you consume. If you mean better mileage as it is cheaper to drive... not so much. Say you get 27 mpg and I get 22, thats 5 MPG difference. If we both drive 10,000 miles .. You use 370 gallons, I'd use 450. A difference of 80 gallons of fuel per 10,000 miles... @ $3 a gallon you talking a savings of $250 every 10,000 miles... big deal.

There has to be some other reason, and I agree the V6 is an AMAZING machine, i am not taking that away from it... Just looking at the other side of the coin... throwing good money at bad.

The most I've seen from a M6 V6 was about 269rwhp.
