Default I have a question

Does it mater whether an engine is a V8, V6 or I4; if it makes the power you want. I ask this because some of the newer V6 and I4ís make more power than recent V8ís. If there were a Turbo V6 that made the power of current V8ís would there be any reason not to choose it. Recently Iíve seen valley mounted Twin-turbo V8ís from Germany N63 , but to my knowledge there are no valley mounted Turbo V6 engines.
If GM were to build Ė say a 420 HP/420 lb-ft 3.6L valley mounted Turbo V6 based on the LFX engine for various new platforms, would this be a good thing. I think the Grand National GNX was just ahead of its time.

I take it that your friend is very pleased with the upgraded performance of his V6 Mustang and does not care that it’s not a V8.

If your happy with the power then its all good!!!! V6 turbos will be the wave of the future for sure.... some racing teams will even be going to them... .... and i have a weird feeling you are trying to share something your not supposed to say........

i would surely buy a v6 turbo....... the first sports car that i drove was back in 87 and it was a GNX to the prom...(my big boss lent it to me for the weekend...).. my girlfriend was a bit embarrased cause she thought i told her the car was cool...... but was disappointed till every guy at the prom swooned over the car and she didnt stop hearing about it for weeks.... needless to say... i might have got lucky... ....

v6 turbos have so much potential.... and i dont think they have tapped into it fully as of yet... but they will.... i am sure of it... it is the future of sports cars.... imo....

I'll take a 400hp V8 over a 400hp V6 every time. A naturally aspirated engine just gives better power delivery through the rev range, is probably more reliable overall, and just sounds better. I just think overall its a better way to go than forcing a smaller engine to make more power.

IMHO, the V8 has more torque and capabilities overall......power by itself isn't everything......

OK ! I did a post a while back suggesting a 4L V8
http://www.g8board.com/forums/showthread.php?t=57609
twin turbo would be nice-some thought maybe too much. But to me more is better.

AMG is currently looking to replace their 6.2L with a turbocharged 4.0L V8. I know their motivation is different than ours, but it's exactly the trend you're talking about.

Sure there is, it's called boost...piew piew lol.

I will say coming from imports to a v8 platform; simple mods are alot beneficial. I had a 2.7L V6 Tiburon and it took i/h/e and a tune to barely break 200WHP. And with my SR Swapped S13 I had to turn up to boost for the real fun to start. Now v8 with boost....mmmmmm

But then you get into the arguement about "if a larger displacement engine has the same psi of forced induction..."

That said, Santa forgot to bring my tvs2300.

It has taken me some time to get back to you because of XMAS, I really liked your story. Don't suppose you had a chance to flex the GNX's muscle back then.
I was trying to stir thing up and talk about the future of the SB, but it appears GM has opted for an update SB instead. The new engine (LT1) will have direct injection, variable valve timing, and cylinder deactivation. The new engine can run in V4 mode ( 3.1L ) - now theres a thought, valley mounted turbo V4 ( which should be inheriently balanced ). I've never seen a V4 on an automotive application, but it would be interesting. Change dose not necessarily mean advancement, but without change there can be no advancement.

i looked at ecoboost f150's, but could not consider one because of the sound... either no sound or a terrible sound with exhaust... the way the car sounds is a big consideration point for me. I like loud muscle... and I am not a fan of the sound of loud 4/6 cylinder cars.

This. And look at it like this post below that original post

I4 NA=150 hp
I4 turbo=250hp
v6 NA=220hp
v6 turbo=300hp
v8 NA=350hp
v8 turbo=450 hp

Therefore there is no replacement for displacement.

I just got a car put on me not too long ago by a stock 4.6 Mercedes Benz.
2012 S550 4.6 Bi Turbo. 400+hp/500+lbft with all wheel drive- as fast as older AMGs.

The new Corvette LT1 engine makes 450 HP NA, but power is not intirely what this is all about. After market mods for power are just that-for power.
Production engines must also be able to make power and have good fuel economy. IF you just want power, that can be done many ways, but power with economy is more complicated and costly.

Agreed, I hate these little "Tuner" cars with their flowmasters and the garbage can sized exhaust tip. Nasty, nasty sounding. There is no comparison to the sound of a large displacement big block.

I love the kids that want to argue that a 4 cyl can be made to destroy V8's and then get pissy when someone mentions the V8 can turboed/supercharged as well.

IMHO theirs a place for all of it the world of hot rodding. Small displacement turbo 4 cylinder engines are great in small light weight cars while larger cars require larger engines to begin with. Neither are right nor wrong just better for different applications.

I've had both and I prefer V8's, I love my G8 its 1 of my favorite cars I've ever owned but my other favorite was my modded 2004 Cavalier.

I totally agree, I like the fact that "they" mod their cars, I just think they sound horrible.IMO
