Random Ls question

Not open for further replies.
My car ran 11.53@118 and I wanted to run high 10's stock appearing so I tore the motor down to pocket port the heads. When I got the heads off, I couldn't believe the car had gone 12's let alone mid 11's. The heads were full of ridges of casting flash and mismatch and the port shapes were 1960's. awful.

I also have a TTA so I figured while I was porting stuff, I buy a set of those heads to pocket port and put big valves in. Someone on TB.com was selling NOS TTA head sets for like $200 shipped, so I bought a pair. Those heads (basically FWD 3.8L heads) are WAY better. They were designed by someone who kind of knew what they were doing and cast by someone who gave a crap.

Only 3 years was a huge leap and 3800 is way beyond that.

The Buick V6 was a pig off an engine that responded well to boost and EFI, but you cannot change a pig's nature.
And this is why I sold my Turbo T back in the Spring and am focusing on LS-stuff going forward. The LS platform in its worst confirguration is a fantastic starting point for a performance build.
 
When pigs fly.
I got a pig sty instead of a stable.🙂
 
Bzzzt - the turbo does spin when the crank does not.

Cost the same? I can put a turbo onto anything for less than a grand. SC or blower for the same? I'd like to see the receipts.

Done here and good luck.
 
Not spinning means no boost. And I supercharged my 3800 for a couple hundred bucks total lol.
 
And with the bbv open there's very little spinning resistance on my sc
 
I'm seeing a whole passel of misinformation in this thread along with the OP's original question....
To the original question, Not a chance said guy has pulled that off without some seriously deep pockets. Anything is possible with enough money though..... In all seriousness, I could throw a D1SC and a 300 shot on a seriously tweaked 6.2 and do it. Might not last to long but hey it can be done.

In regards to some of the misinformation though:

Yes, an Iron block can support over 1K for much more than a few pulls. Over 1500hp though and you're pushing your luck on a stock block with no mods. (FWHP not RWHP)

No, tuning for a water/ meth system is not a pain, just takes a knowledgeable tuner.

No, a larger sized turbo doesn't have to have a long lag time before boost. An anti-lag system provides the ability to spool up drastically faster than a car with a smaller unit. DISCLAIMER--- Very few cars on the street will have an anti-lag system. Just sayin'.

Yes, hp loss is higher on a supercharger than a PROPERLY sized turbo and accompanying parts. HOWEVER, improperly sized turbo systems will create high backpressure which can surpass an SC in terms of parasitic loss. Which, in all reality, is most of the turbo setups people have on their rides.

In regards to which is better? Neither one, it's personal preference. Btw, some manufacturers have used both on the same motor. A turbo pushing into an SC. Crazy huh?

Not starting static, just clarifying some things I saw were incorrect on both sides.

Take your "science" and get out of here, newb!
