2009 Corvette ZR1 LS9 Engine

[bruxell]

The LS7's redline is 6.5k, which i round up to 6k and most of the power hunched up at low rpms,

What? The damn thing doesn’t even make it’s peak torque figure until 4,800RPM! That’s low for a 7.0???

… add a supercharger where efficiency is usually restricted to a small rpm range and it is just a drag racing engine. Plain and simple.

Because superchargers restrict breathing, that’s what they do… For example, look how restricted the CCX is, it’s a 4.7 that produces 806bhp. It could certainly do better NA…

Have you had a stroke recently???

I doubt that it could go past 180 without 7 or more gears, or you would have to wait for eternity to come to reach top speed.

Strangely, it’s not at all as you say… Look, I don’t actually like referring people to them, but if you need a visual confirmation of how fast this car is, go on Youtube and watch the Top Gear segment on the Z06; it’s an eye opener.

Where is the flaw in my logic!

Weight: 3132
CU/CC: 427/7011
RED: 7,200
Power: 505/6,300
Torque: 470/4,800
LB/hp: 6.2
MPG: 16/26
0-60: 3.7
TOP: 198

Right there…

Someone definitely ate their Stupid-O's this morning.

All i see there is a 6k redline, and by the way that is the twin turbo lingenfelter which is not supercharged. I fell for that trick too!

WTF are you talking about???
Heres the link:

Click the dyno sheet link. If you think that superchargers will make the power band more narrow you clearly don't know anything about them.

and it is close geared too, thats why corvetteres top out at about 150

This guy has to be joking, there is no way someone is this dumb.

oh my god...
The only thing Im going to comment on is the supercharger statement. Adding a supercharger will give a WIDER powerband if anything.

It does 186 with 5 gears and 400hp, 198 with 5 gears and 500hp.
Here watch this video and stfu:

You know, it isn’t often that Slicks, Canuck, 2ndclass, and I all see eye to eye on… well, anything (seriously, if Slicks says the sky is blue, I look up just to check. ). Thanks kiango123; your dumbass, ignorant, incomprehensible, vitriolic ranting has injected a little togetherness into our forum.

I agree with slicks also WTF, Kango definetley got it wrong there, the beauty about big capacity V8's and FI is plenty of torque, although the LSx do have a habit of splitting bores if you get boost hungry( Cast block FTW, stuff the weight).

Slicks originally posted

Narrow gears? You do realize that the Corvette (and most other t56 equipped cars) top out in 5th gear right? A stock C6 Z06 can take 1st gear to 60mph, how is that a close ratio???

Slicks why are you assuming that a close ratio g/box wont have a high first gear, think your mixing up short geared with close geared.

Close ratio boxes usually have a high first and closer 2-3-4-5, 5th is usually a
1:1, they are designed to keep small capacity engines in the fat part of the toruqe-power curve

Eg T 50 standard box

Nah mate, its just a standard Australian delivered KE25 Corolla, it may be getting some Levin flares once I find some more HP though . It only runs a 4age20v 1600cc at the moment and we all know 4 cylinder = grocery getter or so Ive been told

The TE27 Levins are getting quite popular with restorers now

I've looked all over for an SR-5 -The US equivilent of the Levin, or Corolla Sport, or whatever it was in so many markets... they're expensive as hell for what they are, if ou can find one. And one importer over here wanted something like $15,000 for a true Levin; that's when I stopped looking for one. Great car though! And a 20V? That's what I have planned for an the MR2 I'm now looking for. Good taste! And yeah, you can get groceries in one, but then, I'm pretty sure the 'Vette has a big enough trunk-space for a weeks shopping.

yeah a good imported one costs the same here, I love the little cars but 15 grand, dont think so

I had a quick peek out the window because I thought I saw the 4 Horsemen of the Apocalypse, but I was wrong.

Weird though...
