Is 300 N A WHP feasible for the V6?

[SIXJAK]

Seeing BBK's youtube thread claiming an 18 HP peak gain from an already base 255 (250-260 seems typical for base) WHP stock got me to thinking. That's 268-278 whp. Worst case scenario you're 32 HP away from 300. Best case 22 hp away from 300. Is there enough left in the remaining aftermarket parts to squeeze another 22-32 hp? CAI, x pipe, axle backs, tune, throttle body tricks, whatever else.

What is the most HP anybody has seen so far on a naturally aspirated V6?

Absolutely...it's completely feasible....

It'll take some work, but yes, you could do it..

This has been asked before, mostly in one thread in the V6 section started by member "bmwdon". I suggest you find the thread called " LLT V6 stock flowrates....simply sad!".

But it is a long thread. This guy (between working on other threads) is building a pretty powerful NA camaro V6. Typically, most guys with exhaust, cold air intake, long tube headers, and a tune are seeing in the 260 to 270 + range...and those are automatics. (by the way, bmwdon's car is an automatic). Manuals dyno a bit higher because of the less drivetrain loss, but honestly I don't know if there are many, if any manual dynos around here with all of those mods listed above. I would think those mods with a manual should get you in the 270 to 280 range easy.

But he is also doing custom ported TB, intake, and heads....he has yet to have the heads installed and a tune done, but I think during his last dyno he hit in the mid 270s. I believe he should be able to hit somewhere in the 280 to 290 range once it is all said and done, but I'll be suprised if he hits 300rwhp. But still...for the automatic, assuming the dyno is accurate (take most of em with a grain of salt) at 280 rwhp....that equates to roughly 350 - 360 crank horsepower. Now that is impressive if you ask me.

Do the same to a manual which we see typically dyno at least 10+ HP better than the auto, and yes I think 300rwhp NA IS POSSIBLE.

Thanks for the heads up. I'll check it out.

I can't speak for the 3.6L V6 in the Camaro, but I've seen several NA 3.8L V6 motors in Grand Prixs/Monte Carlos pushing anywhere from 300-350hp....

Right now, the market's probably a little soft on parts, but with the right time and configuration, anythings possible.

KMPrenger stated it pretty well, you're going to be looking at extensive mod work to make it work....but shoot...350hp at the crank is nothing to laugh at on a V6...especially if they never see you coming

I'm not sure if a cam is out yet for the V6, but adding that along with some decent upgrades would push you into an area usually reserved for V8's

Some good mods listed there, and the thought of getting 330-350hp/270-280rwhp is pretty tempting for when the warranty goes away in a couple years. Unfortunately the whole emissions-legal issue kills any possibilities for me - this is my only car. I wonder what you'd be able to make with shorties instead.

I'll have to read that thread myself, I'm wondering what that mods list does for 0-60 and 1/4 mi. times.

Alot of stock manuals dyno at 250 and up so I think 300 is very achievable.

I think making the V6 Camaro as light as possible and with a lot of good suspension parts, that would crush a heavy V8 camaro around a autox or track would be cooler than a V6 that could keep up with a V8 in a strait line

ditto, gotta look at the weight savings from the headers on down w/ AM, also dropping from 20s(RS) to 18s, etc...

[bmorecam]

another thing you have to consider is gear upgrade.. although, you wont actually see any increase on a dyno but the change in time and feel will be dramatic. Just a 3.73 gear upgrade on a manual v6 is seeing something equal to almost 50lb tq according to apex.
Not there yet but I can see from couple month of lurking on v6 that the upgrades are getting better by each day.
I currently have a manual and have a long tube but as soon as I can get my hands on one of those vararam intake I will most likely get a tune and have it dynoed, so we will see.

[DarkneSS]

Keep in mind these cars have only been on the market for a couple years, thats not that much time...

Id say in a maybe two years 300 wheel horse power will be quite feasible, full bolt ons, a good tune and maybe even cams should do the trick.

And like bmorecam stated above take advantage of the gear options! From the import tuner crowd I came from I can tell you right now they would drool knowing they could upgrade to 4.11s!

[KMPrenger]

Didn't mention gears because the topic of this thread was strictly power talk, but yes, 3.73s would make a very nice different in "seat of your pants" feel.

Not sure if anyone will ever do cams for our car since we have 4 of them, and it would likely be super expensive...but who knows!?

[whitetiger777]

Noob, confused here. I thought the v6's were rated at 304 to 316 hp anyways...Was that at the crank then?

[Lazerbrainz2k3]

Wouldn't changing the gear ratio help with the torque which, from what I'm reading, isn't going to be helped all that much by all those hp mods in the other thread?

312 at the crank. Though I'm confused about whether that's for the manual or the automatic now - I didn't know there was a difference.
