16v sounds like **** /thread

JohnMc 08-11-2020 10:28 AM

16V and a light flywheel takes a whole hell of a lot of 'tractor' out of a redblock. Whether or not you like that is a personal preference.

I've gone from 8V to 16V to LS in my 240, and I feel that it's gotten better each time.

16V all day long cause I can rev up high and shift where I want, not because the 8V choke line forces me to - and because they look better. The 8V head just looks lacking in a large Volvo engine bay...

Yup, a wide powerband sure is nice.

With just some bolt on parts my 8v runs like that all day long as well. But from the factory Volvo didn't ever give us an 8v like that. Plus back when we got the 16v cars hardly anyone here in the US wanted to enjoy shifting gears, sadly.

there's a lot of different ways to skin a cat. Put me in the "a nasty 8v sounds better" camp. I've never considered a 16v swap; I'd just put a different engine in it at that point.

True, but that particular 8v is an extremely high budget one :-P

Tate Fanning drove my ****pile a couple weeks ago. Despite making half the power that his car puts out, the following words came out of his mouth and stayed with me: "I wish I had gone 16v".

And that, sir, is all I needed to hear!

This is sound logic. Being in the middle of a 16v swap, I can honestly say I wish I'd gone whiteblock. Purely for the sound and the coolness factor.

You will love it. Add some cams and you will **** yourself laughing.

Ahh the glorious 8v at full sing. Listen as I cross the finish line in this quarter mile drag race and then shift into fourth and get on it some more just for fun, after the finish line...

Ohh and no big valves and no big money, stock b230ft with A cam and junkyard 15g..

Now got head resurfaced on the 90 745 550k mile car, gonna put a 19T on it and go draggin ASAP. Wanna talk sheet about your big valve small valve LS BS then lets see your times beeches!

2manyturbos 08-18-2020 03:12 PM

Dude, a stock LS will run those times. Not LM, LQ. LS1-9. Not knocking your build. Just get real.

Mine's a decent argument against it considering the cost, but I also spent a LOT of that money on like the last 10% of improvements.

Yeah but that's Tate's opinion, can we really trust it? Such a dubious character :-P

I can't say anything because I haven't been to a track in a long while... but yeah. 500-ish HP pulls HARD in those top gears.

Real? Where is your real timeslip Bro?? Keep posting sheet and not posting your timeslip and yeah I'll buttleve ya.



My goal is to be the fastest in the West this year redblock, you can be fastest in the west LS all you flucking want. Let's see who actually does anything. I might be just full of it. We shall see..

I'm not even sure if the track is open. Someone told me today only open to real racers.. Me no real nuttin..

Sorry Bro. It's straight forward physics, not magic. Curb weight on a 2004 C5 Z06 is 3116 lb. Factory rated at 405 hp. 12.6 second quarter mile. That Z06 weighs ~ 600 lb more than your 740. A Z06 is not set up for weight transfer. That's just brutal horse power/torque pushing that car set up for handling through the quarter mile that quick. That LS engine doesn't care whether it is in a Corvette body or a 740 body. Aerodynamics isn't much of a factor at the speeds you are hitting drag racing. That time is on street tires, not slicks. You are not going to compete, let alone beat, a properly set up LS conversion. I think Andrew is in the 9s, IIRC. You might just be the fastest redblock on the west coast. I'm rootin' for you.

Right. I did look at the others. I was just comparing the most basic LSX engine. The C5 ZO6 makes 405 hp. The C6 Z06 LS3 makes 550 stock. The LS engines are light weight brutes.

JohnMc 08-18-2020 11:11 PM

yeah, jsut a non sequitur. Imagine what the Z06 and ZR1 C8's will do. If they can keep the rear suspension in one piece (and under warranty).

C6 Z is the 505hp LS7.

LS engines have character like redblock variations too. My dad's had a fleet. 6.2 in the Denali that feels like a big truck motor. Had a C5 Z with the LS6. Just sold his C6 Z with the LS7 (obvious favorite). Likely bringing home next week a CTS-V wag with the LS...A? Right? will be the first charged one.

JohnMc 08-19-2020 09:09 AM

A CTS-V 6-spd wagon just sold on BaT for $55K. Seems like it would probably be fun.

because you're only like $8 into your 16v...right? For it to make less power and have nearly the same powerband as my old ****ty 75.

Harlard 08-19-2020 01:26 PM

I have nowhere near close to 8k on this engine. Let's feed it 30 PSI and E85 and see what happens.
