It's kinda odd that Superchargers on Vettes make just about as much power as turbo's do...yet on VQ's they make FAAARRR less to the point where it's even odd. In the vette/fbody forums you can see even 1000whp supercharged setups with more or less the same mods as a 1000whp turbo setup. Here I see a 477whp vortech setup with all kinda of other add ons that the turbo setups don't need to make that power.

Centifugals are very efficient so my question is...why? Is it because the head units that are being used as on the small side to make better low end torque? Why not use an intake restrictor like the Vette/Fbodie guys do to get the best of both worlds with a large head unit ( allows good boost in the lower rpms and restricts extremely high boost from occuring in the higher rpms )?

Considering the lack of engine bay space these cars have...I would think supercharged setups would be more popular than they are.

there is a TT G sedan for sale here with almost 1000 WHP right now.

1000 HP sedan, how did I miss this? Link?

^Yeah, I've seen that one, but its a coupe. I didn't' think any sedan was making more power than Tim.

I think you guys misunderstood me... I know the turbos can do it....but why no 500whp supercharged G's?

Not that I have heard.

Me neither...and I see no real reason for it other than lack of people actually caring maybe.

Heck...I've seen 500+whp Supercharged VW VR6's and those engine suck horribly in comparison to the VQ35DE ( 2.8L V6 172-178hp vs. 3.5L V6 280-298hp ).

I guess the question would be:

What exactly does it take to produce a 500WHP/500TQ SCed G35 coupe/sedan? What parts/work would it take for the engine internals, fuel system, tune, actual SC kit and necessary supporting hardware to safely produce 500+HP/TQ #s?

If someone's done it already, how exactly did they go about it?

After being a member here for about 3 years, what I have seen as "the rules":

FI > 400 WHP you are good with stock internals, clutch, tranny (I really think it's closer to 350)

Up to 500 WHP, and you need a build (bottom end, rods pistons (8.5:1), oil pump, more cooling (water, oil, tranny), Valve body mod on AT tranny, clutch on MT, etc.

Over 500 WHP To the above you need sleeves and special heads cometic head gaskets ARP studs, complete upgrade on AT, or Clutch pack.

BUT.... why has no one done it on a supercharger?

check out Hexxum's thread in the sticky section of this sub-forum. He's compiled a TON of stats on members here with FI and stock internals.

This one claims 440rwhp on the Vortech kit, but I think it's pushing the upper limits. I completely agree w/ Texas ... anything more than 350 and you should consider building the engine.

you def dont need sleeves for above 500rwhp, i've seen plenty of 600+rwhp Gs and Zs on my350z w/ out sleeves


the main reason you havent seen it, is cause the easiest way to get to 500rwhp is by going turbo

I don't think it's possible to create "turbo levels" of boost with a supercharger. The belt slips at normal boost... that much boost would be difficult.

Someone here built a "cog" belt system for their Vortec.
