Jeff from EP that makes the good limited slip diffs ran his Bonneville that is twin charged, T67 on it, with a 4t80 in it.. Ran a 12.8.....that was on slicks too and he could definitely launch that thing

Typical response from an internet "badass" who has nothing educated to respond with. Go be uneducated somewhere elseOriginally Posted by Fivefingerdeathpunch
Fair enough. When my 5-speed swap is done, she'll be hitting the track in September at a friend's track rental.

Yup I'm uneducated.
Being a badass is tough work these days.

On the LSD:
Very quick 60' times are there with stock HD diffs.

So why use a clutch based diff that will add more clutch material to your trans system if the place where you'd notice the biggest difference would be the autocross or road course?
To the OP of this thread: If you have to ask, you probably won't do it. Pretty much the standard with this platform. Anything worth doing is more worthwhile doing in a different platform.
To ls1camino: To claim that the blower isn't a restriction is rather interesting.
The rotors were not designed to move compressed air, many different paths of logic would suggest many different things. Until we see some test results of the blower on a blower test rig, claiming one thing or another is kinda pointless.
Dyno results or track slips do not count as evidence to support claims such as "the blower is not a restriction".
To claim you'd destroy other cars with similar internal mods is also an interesting claim.
A stall is not an internal engine mod thus the larger turbo car could have a larger stall and thus spool the larger turbo and theoretically have similar torque/power available to it throughout the run.
Tires will not solve the inherit issues with launching a W body. Chassis has numerous flaws such as the weak LCA design and FWD layout. Plenty of time can be shaved off of your ET by focusing on suspension, even if the car is otherwise stock.

well im planning on going all the way with my build, hence why im asking these questions now, you have ot make up your mind where you want your build to end up, and then plan the best way/order to do all the mods.... and without wasting money, i dont want to buy **** im going to wish i didnt later on... and if your worried about wheel spin yeah get some 15 inch steelies with some slick on them and throw them on when you get to the track... and my current project is replacing the entire suspension, sway bar, trailing arms, poly end links strut braces etc. i just wish coilovers for w bodys cost as much as the ones for a civic, that **** is like 12.99 at walmart for a 12 back in assorted color

if i were you i'd go with a turbo build. if twincharged was truly superior don't you think all the japanese 4cyl rockets would be twincharged?
no, they are all turbos

4 bangers make no power till higher rpms, it takes power to make power, a honda b motor has like 12 horsepower at idle, i dont think they could turn a blower AND a water pump lol

I would think it would just depend on what you plan on doing with the car. For full throttle runs I would think that you could properly tune a turbo only setup to work better than a twin charge. For something like autocross, where the RPM range is all over the place, the twin charged setup would probably keep your boost levels up without running a high stall converter and sacrificing driveability. Personally I am intrigued by the idea of twin charging, even if it is not the most practical way to go. Probably because the combination of the engineering gets me happy in the pants.

Wow is all I can say. Lots of non-research here.
I would sequentially twin turbo a car before I ever twin charged with an M90, but that's just me.
As far as the argument of twin charging being better than a single turbo.... It's so relative its ridiculous to ever ponder without citing specific build sheets with track times to back them up.
There is a reason most people have NOT done twin charged cars. I am actually surprised that Darkhorizon hasn't added his 2 cents yet. lol
TVS1320+ twin charged?!

Look at Parish's truck, he did both (twin and single) and made the most power single. I guess the application could change things, but I think more and more people are finding better results in single turbo setups.
I've been thinking about the how twincharging works for some time. For twincharging to work best, both power adders would almost have to be paired perfectly to peak around the same rpm. If the suprcharger is a restriction, there will be excess pressure releived through the wastegate or blow off valve preventing damage.
One thing that would be a necessary precaution I can think of would be head studs, as in any high boost application.

The subject has been beaten to death and there are pro's and con's to each setup. The M90 does not become a restriction. That is all.

I'm suddenly embarrassed to be a member of this forum.
